In addition, spacing distance between the two terminals location rib 109,109 is made into to approximate the size on above-mentionedbattery side terminals 120 fore-and-aft directions, and twoterminals location rib 109 roughly on the direction to the right, the right side edge of the battery side terminals after connect partly extends, and being shaped on littleoutstanding bar 110 integratedly at the left end place ofbattery side terminals 120, they extend in the opposite direction.Built near thebattery side terminals 120, such as the jut of little outstanding bar 110,110 and above-mentioned terminals location rib 109,109 etc. be used as difference label 111,111 ..., be used to distinguish the type ofbattery pack 100, hereinafter will be described (referring to Fig. 7) this content.

Whenfore shell 105 andback cover 106 combine, theright part 109a of above-mentionedterminals location rib 109 overhangs outoutside back cover 106 1 side direction, and whenbattery pack 100 is loaded into battery on thecamera body 2 and packs in thepart 10, theright part 109a ofterminals location rib 109 just becomes upside and treats a part in thelock portion 112, be encased in pack into the content of part aspect of battery about battery pack, will be described (referring to Fig. 8) hereinafter.

Rear-lateral corner atback cover 106 upper surfaces is partly located, be provided with a less relativelyconcave part 113, this concave part upward with the rear opening, whenbattery pack 100 was loaded into battery and packs in thepart 10, this littleconcave part 113 had just become upside and has treated a part (referring to Fig. 8) in thelock portion 112.

In addition, on the 106b of the bottom surface ofback cover 106, be shaped on one in front and back upwardly extending bar shaped recessedtreat lock groove 114,lockable mechanism 40lock pawl 41 can be locked in (described below) in this lock groove on thecamera body 2, and treats that lockgroove 114 is also as the lock portion 112 (referring to Fig. 6) ofbattery pack 100 downsides.

By this way, be provided with by each position and treatlock portion 112 at battery pack one rear flank shell 106 (promptly at a device), beright part 109a, the recessedportion 113 of terminals location rib and treatlock groove 114, the positioning accuracy (referring to Figure 15) in the time of just can improvingbattery pack 100 and be loaded into battery and pack in thepart 10.

That is to say, along with theback side 106a (left surface) ofback cover 106 contact with a bottom surface 15 (referring to Figure 15), and meanwhile, along with battery pack one each position of side treat lock portion 112 (beingright part 109a, recessedportion 113 and thelock groove 114 of terminals location rib) by pack into corresponding lock portion (overhang 17 that promptly hereinafter will be described,small embossment part 20 and the lock pawl 41) locking ofpart 10 1 sides of battery,battery pack 100 just has been installed into battery and has packed in the part 10.If being set, each treats lock portion 112,112... on a plurality of devices, for example onfore shell 105 andback cover 106, these are set and treat lock portion, so, as accurately being assembled into a time-out inadequately whenshell 105 andback cover 106, then play can when locking state, occur, and problem also can take place in the connection status between battery side terminals and the mainbody side terminals 30.

Thereby, for the situation onbattery pack 100, by with the above-mentioned a plurality oflock portion 112 centralized systems parts (being back cover 106) therein for the treatment of that are used to position, positioning accuracy in the time of just can improvingbattery pack 100 and be in installment state, the required precision in the time of so just can reducingback cover 106 and combine withfore shell 105.

In addition, infore shell 105 and above-mentionedbattery side terminals 120 corresponding front upper part offices, made a sunkpart 115, its highly basically withback cover 106 onconcave part 107 contour, and be shaped on aterminals pressurization fin 116 at the left side edge place of sunkpart 115, it is used for from the right sidebattery side terminals 120 pressurize (referring to Fig. 7 to Fig. 9).

Terminals pressurizationsfin 116 the length on the fore-and-aft direction be made into above-mentionedback cover 106 on twoterminals location rib 109, spacing distance between 109 is roughly the same, that is to say, almost withbattery side terminals 120 measure-alike on fore-and-aft direction, thereby, whenfore shell 105 is assembled on theback cover 106, terminals pressurizationfin 116 will be positioned at two above-mentionedterminals location rib 109, between 109, and carry out roof pressure, twoterminals location rib 109 on theback cover 106 from the left side to battery side terminals 120,109 than stretching out (referring to Fig. 8) slightly to the right as the twoterminals pressurization fin 116 for the treatment oflock portion 112.

Battery pack 100 for the normal capacity model, the battery unit 102,102 of two rectangle stereo structures is encapsulated in the battery case with forming a line, and above-mentionedsubstrate 104 is installed in the top of battery unit, and above-mentionedbattery side terminals 120 and IC chip 103 then are installed in the front and rear (referring to Fig. 4) ofsubstrate 104 respectively.

In such a manner, because there is skew the position that is provided with ofbattery side terminals 130 in one direction with respect tobattery pack 100, so just can form relatively large space in its opposite side, thereby the electronic unit such as IC chip 103 grades just can be set in this space, and then improve utilization of space.Specifically, when thebattery unit 102 of rectangle stereo structure is set in thebattery case 101, do not leave any dead-space volume, thereby battery unit 102,102 can be arranged in thebattery pack 100 effectively.Although it is inconvenient reserving installing space forbattery side terminals 120 and integrated circuit (IC) chip 103 etc. from the outstanding element of battery unit onsubstrate 104, but by as described abovebattery side terminals 120 being arranged on the position with respect tobattery pack 100 skews, just effective utilization (referring to Fig. 4 and Fig. 7) of energy implementation space.

In addition, becausebattery side terminals 120 are set on the position that is offset with respect to battery pack, so can prevent frombattery pack 100 is installed on thecamera body 2 mistakenly.

Meanwhile, hereinafter will be tobattery side terminals 120, as admitting therectangular slits 108 and the assemble method of side to be described in detail on thebattery side terminals 120.

Below, will be explained in detail the battery ofcamera body 2part 10 of packing into.

Pack into the upward and downward size ofpart 10 of battery is made into to be slightly larger than the thickness (i.e. thickness on left and right directions) of theback cover 106 of above-mentionedbattery case 101 on the camera body 2.Thereby, to be installed to battery inbattery pack 100 and to pack under the state on thepart 10,back cover 106 is located in pack into the inside ofpart 10 of battery, and the nearly all part on thefore shell 105 all fromcamera body 2 outstanding (referring to Fig. 3 and Figure 15).

Be provided with mainbody side terminals 30 in the position relative with above-mentionedbattery side terminals 120, that is to say: mainbody side terminals 30 are arranged on the inner surface (being its lower surface) of upperledge support body 13 and the office, bight between thebottom surface 15, perhaps also can say it is the position, oblique angle (referring to Figure 10) that is positioned at the front upper place.

With aforementionedbody side terminal 30 corresponding zone, position is set, made a part that overhangs 17 downwards, wherein said zone is the open side edge (right side edge) on upperledge support body 13 inner surfaces, and the size thatoverhang 17 and battery are packed between thebottom surface 15 ofpart 10 is designed to and theback side 106a of above-mentionedback cover 106 and the distance identical (referring to Figure 15) betweenterminals location rib 109 right parts.

The result: whenbattery pack 100 was loaded into battery and packs in thepart 10, the right end portion ofterminals location rib 109 will be blocked byoverhang 17, and does not have play between the two.Correspondingly, just can realize locking with such state: the front region onbattery pack 100 tops is interior without any play (referring to Figure 15).

Integrally make an outstanding bar 18 (hereinafter being referred to as " blocked portion is given prominence to bar ") from the rear portion ofoverhang 17 to pack into the bottom surface (left) ofpart 10 of battery, and the end portion of theoutstanding bar 18 of this blocked portion extends to the position (referring to Figure 10) that separates suitable distance withbottom surface 15, thus not with above-mentionedbattery pack 100 back covers 106 on above-mentioneddifference label 111 interfere.

Can theoutstanding bar 18 of this blocked portion be loaded into as blockedportion part 19,decision battery pack 100 with near thekick part 18a that hereinafter will describe, be arranged on the main body side terminals 30.Meanwhile, since above-mentioned blockedportion part 19 be made into not withbattery pack 100 on 111 interferences of difference label, so allowing thatbattery pack 100 is encased in battery packs in thepart 10, although at certain equipment, for example in flash lamp for photography 150 (battery pack 100 of the low capacity of will not packing into this moment), thisbattery pack 100 of can packing into does not allow the situation of packing into but exist because the capacity ofbattery pack 100 is different.

In such circumstances, above-mentioned blockedportion part 19 is designed to like this: its battery pack intopart 10bottom surfaces 16 near on extend, thereby with above-mentioneddifference label 111 interferences, stopbattery pack 100 thus and do not allow it to pack into.Whether allowbattery pack 100 to pack into to be to determine hereinafter detailed description to be arranged to this by the form of position relation between thedifference label 111 of above-mentionedbattery pack 100 1 sides and the above-mentioned blockedportion part 19.

With the littleconcave part 113 corresponding positions of above-mentionedback cover 106, be shaped on asmall embossment part 20, it can accurately combine (referring to Figure 10) with littleconcave part 113, this position is pack into the position, turning of inner surface 13a (being its lower surface) andrear frame body 12inner surface 12a (being its front surface) of upperledge support body 13 ofpart 10 of battery, andsmall embossment part 20 on battery is packed thebottom surface 15 ofpart 10 into be provided with position and littleconcave part 113 onback cover 106back 106a that the position is set is consistent.The result: whenbattery pack 100 is loaded into battery and packs in thepart 10, can be without any the posterior region on locking battery pack top, play ground.

Be shaped on the hole 21 (hereinafter being referred to as " go up push pedal the hole is set ") of a rectangle in pack into the central position of 15 bottoms,part 10 bottom surfaces of battery, and be shaped on a kerf part 22 (hereinafter being referred to as " locking rod is provided with the hole ") on the inner surface (being its upper surface) of lowerframe support body 14, thisnotch portion 22 is made into above-mentioned lastpush pedal hole 21 to be set and extends for one (referring to Fig. 2).

Lockable mechanism 40 comprises: a lockingrod 42, and it has alock pawl 41, and it engages with thelock groove 114 for the treatment of onbattery pack 100 bottom surfaces; Pushpedal 43 on one, and it is used for, and thebottom surface 106a tobattery pack 100 exerts pressure on the direction thatbattery pack 100 is thrown off; Oneanti-bouncing pin 44, be used for when utilizing above-mentionedlocking rod 42 to remove locking tobattery pack 100, prevent thatbattery pack 100 from popping up, these lockingrods 42, go up pushpedal 43 andanti-bouncing pin 44 is supported on rotationally by abase plate 45 on the same axle, base plate wherein is positioned on the inboard of 15 corner parts of lowerframe support body 14 and bottom surface (referring to Figure 11 and Figure 12).

Like this,base plate 45 just is in the inboard of lowerframe support body 14, and be fixed on the lowerframe support body 14, the above-mentioned locking rod that above-mentionedlocking rod 42 is set at lowerframe support body 14 is provided with in thehole 22,last push pedal 43 is arranged inpush pedal hole 21 is set,anti-bouncing pin 44 then is in the rectangular slits 46 (hereinafter being referred to as " anti-bouncing pin is provided with the hole "), and thisotch 46 is provided withhole 22 with locking rod and is connected as a single entity.

In addition, suit thewind spring part 48a of ahelix torsion spring 48 in arotating shaft 47, rotatingshaft 47 is being supported lockingrod 42 rotationally, is being gone uppush pedal 43 andanti-bouncing pin 44, anarm portion 48b ofspring 48 acts on the lockingrod 42, its another arm portion 48c acts in thepush pedal 43, impel lockingrod 42 on the direction that makes progress, to rotate thus, and impelupward push pedal 43 on direction to the right, to rotate (referring to Figure 12).

Lockingrod 42 is suitable for having such face shaping: the global shape of its side is alphabetical L type, and oneupper surface member 49 is made into to become the part of above-mentioned lowerframe support body 14 inner surfaces (being its upper surface), cross sectional shape is that leg-of-mutton lock pawl 41 is formed on the fore-and-aft direction, and extend to such position: it departs from the center of rotation ofupper surface member 49, be shaped on anoperation part 50 in the bottom of right flank, be used for lockingrod 42 is operated (referring to Figure 11 and Figure 12).

Thereby, lockpawl 41 just has been made into like this: its slightly on the direction to the right (front side) from pack intobottom surface 15 skews (in the front side) ofpart 10 of battery, and equal the distance of thebottom surface 106a that treatslock groove 114 of the above-mentionedbattery pack 100 of distance apart from the size ofbottom surface 15, thereby, whenlock pawl 41 and when treating thatlock groove 114 engages,battery pack 100 can be pressed onto battery pack into (referring to Figure 15) on thebottom surface 15 ofpart 10 naturally.

In addition, left and right sides part at theupper surface parts 49 of lockingrod 42, be provided with twolittle projections 51,51 respectively, they contact with the two edges part that the locking rod of lowerframe support body 14 is provided withhole 22, and the edge part phase-splitting card that these twoprojections 51,51 are provided withhole 22 under the actuating of above-mentionedhelix torsion spring 48, from inboard and above-mentioned locking rod hits, thereby is lived by blocked portion.Under such state, the upper surface ofupper surface parts 49 is concordant with the upper surface of lowerframe support body 14.

Be shaped on twowidgets 52,52 in thelast push pedal 43 integratedly, they stretch out downwards from center of rotation, and these two widgets are subjected to the effect of describedhelix torsion spring 48 and contact with above-mentionedbase plate 45, thereby are lived by blocked portion.Under this state,last push pedal 43 is in such state: it is provided withhole 21 to right-hand projection (referring to Figure 12) from last push pedal.

Anti-bouncing pin 44 has aspiral compression spring 54, and it is compressed between the lower surface and aprodger 53 of a pivoting end, therebyanti-bouncing pin 44 is just similar with described lockingrod 42, is also upwards pushed up (arriving Figure 16 referring to Figure 13) rotationally.Explanation in passing: in Figure 16, describedbattery side terminals 120 and mainbody side terminals 30 are not all drawn at Figure 13.

Be shaped on aclaw part 55 on the rotation end ofanti-bouncing pin 44, this part is shaped on one integratedly at the bottom part of preventing bouncingpin 44 and rotatesblock piece 56 to upper process, and it is forwards outstanding.Utilize arotation block piece 56 and a locatingpart 57 onsubstrate 45 to hit and be stuck, just stopped thatanti-bouncing pin 44 rotates under describedspiral compression spring 54 effects.Under this state, above-mentionedclaw part 55 projects upwards (referring to Figure 13 to Figure 16) from the upper surface of lowerframe support body 14.

In addition, theclaw part 55 ofanti-bouncing pin 44 is formed than thelock pawl 41 of lockingrod 42 more keep right (referring to Figure 13 to Figure 16).

In such a manner, whenbattery pack 100 is in when not being loaded into battery and packing state in thepart 10 into, thelock pawl 41 of lockingrod 42 and theclaw part 55 ofanti-bouncing pin 44 just project upwards from the upper surface of lowerframe support body 14, and go up pushpedal 43 and be in from pack into the outstanding to the right state (referring to Figure 13 or Figure 16) in bottom surface ofpart 10 of battery.

Like this, will be installed to battery when packing on thepart 10, will carry out a process in such a way, and will be encased in thebattery pack 100 that battery packs in thepart 10 by above-mentioned lockable mechanism and remain under the lockup state whenbattery pack 100.

At first,battery pack 100 is inserted into battery with the attitude of its upper angled packs in thepart 10, and battery side terminals 120 (comprisingterminals location rib 109 and the pressurization of the terminals on thefore shell 105fin 116 on the back cover 105) are slided into pack into the inboard ofoverhang 17 ofpart 10 of battery.Thereby, as mentioned above: because thedifference label 111 that is positioned atbattery pack 100 1 sides do not interfere with pack into the member (blocked portion part 19) ofpart 10 1 sides of battery, so thebattery side terminals 120 ofbattery pack 100,terminals location rib 109 and terminals pressurizationfin 116 just can slide into (referring to Figure 13) in theoverhang 17 dearly.

At this moment, three wiring element, 31,31,31 (not shown)s of three of above-mentionedbattery side terminals 120 terminals members 122,122,122 and mainbody side terminals 30 just are together with each other respectively.

In addition, as will be described in detail, bybattery pack 100 1 side settingarea distinguishing labels 111 and battery pack intopart 10 1 side settings can with the difference label blockedportion part 19 of interfering mutually, above-mentionedbattery side terminals 120 just can not slide into battery deeply and pack in theoverhang 17 of part 10.Thereby theterminals member 122 ofbattery side terminals 120 just can not combine with thewiring element 31 on the mainbody side terminals 30.

And, even pack in thepart 10 if alsobattery pack 100 is encased in by force battery under the condition of the blocked portion part on battery is packedpart 10 into 19 anddifference label 111 interferences ofbattery pack 100, owing to pack into the upperledge support body 13 ofpart 10 of battery can bend along with the extruding of 111 pairs of blockedportion parts 19 of above-mentioned difference label, so exist battery pack to be loaded into pack into accidental possibility in the part of battery.

But in such circumstances and since blockedportion part 19 anddifference label 111 be formed in twoterminals 120,30 near, drop back on its direction of being oppressed so mainbody side terminals 30 are understood, thereby cause two terminals in fact not to be bonded with each other.Thereby wiringelement 31 andterminals member 122 can not be in contact with one another, and avoid thus electrically contacting.

Then, as rotating fulcrum, the bottom ofbattery pack 100 turns left with the top (being thatbattery side terminals 120 are by the part ofoverhang 17 lockings) ofbattery pack 100, and like this,battery pack 100 has just installed to battery pack into (referring to Figure 14 and 15) in thepart 10.

At this moment, theclaw part 55 on theanti-bouncing pin 44 of above-mentionedlockable mechanism 40 is pushed up under the lower-left side direction ofbattery pack 100, and clawpart 55 engages (referring to Figure 14) with treatinglock groove 114.

In addition, along with the bottom ofbattery pack 100 is pressed towards thebattery part 100 of packing into, theclaw part 55 of above-mentionedanti-bouncing pin 44 will be treated that the marginal portion oflock groove 114 pushes open, and meanwhile, thelock pawl 41 of lockingrod 42 is by the lower-left lateral edge portions of battery pack (being the angle part of bottom surface one side) institute's ejection, then, lockpawl 41 just engages with treatinglock groove 114, has finished the loading procedure (referring to Figure 15) ofbattery pack 100 thus.

In addition, before lockingpawl 41 and treating thatlock groove 114 engages, thebottom surface 106a ofbattery pack 100 makes onpush pedal 43 direction left and rotates, thus make thelower surface 106a ofbattery pack 100 almost be Face to face with the batterylower surface 15 ofpart 10 contact (referring to Figure 15) of packing into.

Thereby, these lockingrods 42,anti-bouncing pin 44 and go up pushpedal 43 and rotation has taken place with regard to the elastic force effect that overcomes above-mentionedhelix torsion spring 48 orspiral compression spring 54.

At this moment, theterminals member 122 ofbattery side terminals 120 just with mainbody side terminals 30 onwiring element 31 dock together mutually, meanwhile, theright end portion 109a that is arranged on theterminals location rib 109 onbattery pack 100 tops engages withoverhang 17, and thesmall embossment part 20 that the concave part on thebattery pack 100 113 (treating lock portion 112) and battery are packed on thepart 10 engages.

The result, top inbattery pack 100, theright part 109a of terminals location rib 109 (treating lock portion 112) engages withoverhang 17, little concave part 113 (treating lock portion 112) engages withsmall embossment part 20, and in the bottom ofbattery pack 100,lock pawl 41 and treat that lockgroove 114 engages so just has been fixed onbattery pack 100 battery pack into (referring to Figure 15) in thepart 10.

Thelock pawl 41 of lockingrod 42 and theclaw part 55 ofanti-bouncing pin 44 roof pressure on the direction that makesprogress battery pack 100, therebybattery pack 100 is pushed up upwards framebody 13, have so just realized the location (referring to Figure 15) ofbattery pack 100 on above-below direction.

The result:battery side terminals 120 are pressed onto on the mainbody side terminals 30, thereby have guaranteed stable bonding state betweenterminals member 122 and the wiring element 31.Especially:battery side terminals 120 and mainbody side terminals 30 are set on the position that is offset forward with respect tobattery pack 100, and, becauseanti-bouncing pin 44 is set at the position that is offset forward from middle position on fore-and-aft direction, that is to say,anti-bouncing pin 44 is set at the position relative with twoterminals 120,30,battery pack 100 is by upwards ejections ofclaw part 55, thereby can guarantee thatterminals member 122 andwiring element 31 stably combine (referring to Fig. 2).

In addition, because the bottom ofbattery pack 100 is bylast push pedal 43 roof pressure to the right, and lockedpawl 41 and treated that the engagement relationship between thelock groove 114 blocks, so realized the location ofbattery pack 100 on the direction of packing into (being left and right directions), in addition, becausebattery pack 100 is subjected to the restriction of thelittle fin 16,16 on theinner surface 12a offront frame body 11inner surface 11a (being its back side) and rear frame body 12 (being its front surface), has realized the location (referring to Fig. 3) on fore-and-aft direction thus.

Thebattery pack 100 that the battery that has been loaded intocamera body 2 is packed in thepart 10 is to split out fromcamera body 2 according to following mode.

That is to say: at first, by just carrying out release (referring to Figure 16) to lockable mechanism with hand or finger pressesoperation part 50.

When lockingrod 42 was operated, it overcame the elastic force ofhelix torsion spring 48 and rotates on downward direction, thus withbattery pack 100 on thelock groove 114 treated throw off.

Whenlock pawl 41 was thrown off withbattery pack 100, the bottom ofbattery pack 100 will be bylast push pedal 43 to left translation, thereby, rise (referring to Figure 16) from pack into thebottom surface 15 ofpart 10 of battery.

At this moment, when the bottom ofbattery pack 100 from thebottom surface 15 when floating high slightly, theclaw part 55 ofanti-bouncing pin 44 engages with treating lock groove 114.Result:, caught because theclaw part 55 ofanti-bouncing pin 44 treats lockgroove 114, sobattery pack 100 can't eject inadvertently suddenly althoughbattery pack 100 is given prominence to from battery is packedpart 10 into.Especially: whenvideo camera 1 is in above-mentioned orienting station (when the attitude of normal photographing), evenbattery pack 100 is carried out release, theclaw part 55 ofanti-bouncing pin 44 can be treated that also lock groove 114 catches, thereby,battery pack 100 can't be deviate from from battery is packedpart 10 into, thereby can prevent thatbattery pack 100 from dropping down.

Then, by catching the bottom by thehigh battery pack 100 of bullet, and (to the right) pulls out with the handgrip battery pack on the direction thatbattery pack 100 is thrown off, then owing to theclaw part 55 ofanti-bouncing pin 44 is thrown off with treatinglock groove 114, so can easilybattery pack 100 be split out from battery is packedpart 10 into.

Below, will at length introducebattery side terminals 120 and be assembled into process on thebattery pack 100.

As mentioned above,battery side terminals 120 are made of aterminals housing 121 and three terminals members 122,122,122,terminals member 122 is that the method by embedded mold pressing is installed in theterminals housing 121, the face shaping of terminals housing 121 is rendered as a flat cube entity, and is shaped on upwards and five grooves 123,123,124,124,124 of opening (referring to Figure 17 to Figure 19) left.

In five above-mentioned grooves, the width of two grooves 123,123 of both sides is greater than the width of other three grooves 124,124,124 before and after being positioned at, and their length and the degree of depth are also greater than other three grooves 124,124,124,groove 123 is used as the guiding groove (referring to Figure 17-19) that positions with respect to mainbody side terminals 30, hereinafter will be further described this.

In addition, three grooves in the centre of above-mentioned five grooves 124,124,124 are provided with groove 124,124,124 as terminals, and be provided with in this each groove a pair of mutually over againstcontact 125, and at terminals groove 124,124,124 inside are set and have formed the spatial accommodation 126 (referring to Figure 17,18) that is used to hold above-mentioned contact 125,125.Incidentally, in Figure 17 and Figure 18, only dotted out aterminals member 122, other two terminals members 122,122 then have been omitted.

In addition, the edge that these two guiding grooves 123,123 and terminals is provided with groove 124,124 open side has carried out chamfered, for example edge chamfer is processed into shapes such as R angle, fillet, cone angle.Thereby, as hereinafter will as described in, the guidingpiece 32 of mainbody side terminals 30 andwiring element 31,31,31 can be easily inserted in these grooves 123,123,124,124,124 (referring to Figure 26 to Figure 28).

Eachterminals member 122 ofbattery side terminals 120 is by being made into integration as lower member: a pair of mutually over against contact 125,125; Thebase component 127 that twocontacts 125 are coupled together; An and lead elements and production method thereof 128.Lead elements and production method thereof 128 wherein is soldered on thesubstrate 104 that is arranged on thebattery case 101, and extends (referring to Figure 21 and 22) frombase component 127 along the direction opposite with contact 125,125.

Contact 125,125 has root and hemisphericbump contact part 125a, the 125a that is embedded in the above-mentionedterminals housing 121, two contact parts are on the tip position ofcontact 125, and at mutual close direction upper process, twobump contact part 125a, 125a do the time spent not being subjected to any pressure, are in the state (being so-called zero contact condition) that is in contact with one another.When the terminals tobattery side terminals 120 are provided withgroove 124 and observe, can only see twobump contact part 125a (referring to Figure 20 and 21).

Thereby, when acontact portion 35 is inserted into terminals when being provided with in thegroove 124, can only touch with twobump contact part 125a, 125a.Nomatter contact portion 35 is that direction from both direction (being left and right directions and above-below direction) is inserted into terminals and is provided with in thegroove 124, because the spring performance of contact 125,125 is identical on both direction, touches together reliably so can both guaranteeterminals 120 and 30.Certainly, although in the above-described embodiments, when installing tobattery pack 100 on thevideo camera 1, just insert on left and right directions, this effect is confined to only to dock the situation that the structure of line end designs.

Base component 127 exposes in a certain position, in this position, base component is connected on the right flank ofterminals housing 121, and lead elements andproduction method thereof 128 is bent into rectangular-shaped, and the lower limb along to the right direction frombase component 127 extends, and basically with thebottom surface 121a ofterminals 121 mutually concordant (referring to Figure 20 and Figure 21).

On the two sides, front and back ofterminals housing 121, be shaped on two in the upwardly extending slide protrusion part 129,129 of right and left, slide protrusion part the 129, the 129th, the edge, the left and right sides of therectangular slits 108 of above-mentionedback cover 106, and with two sliding trays, 117,117 slip joint built interminals location rib 109 downsides, therebybattery side terminals 120 are supported to (referring to Fig. 9) in theback cover 106.

The left end of the sliding tray 117,117 ofback cover 106 is cecums, so whenbattery side terminals 120 and slidingtray 117 slip joint, can carry out the left-hand location to it.That is to say, adjusted position from theback side 106a ofback cover 106 to the battery side terminals.

Two groovings 130,130 have been made, they are respectively at position, turning between right flank and the leading flank and the corner part between right flank and the trailing flank, and adjoin mutually with the upside of above-mentioned slide protrusion part 129,129, grooving 130,130 engages (referring to Fig. 9) with two projections 118,118 built in the left side of above-mentioned terminals pressurizationfin 116 rear and front ends.

Thereby thesebattery side terminals 120 have three lead elements and production method thereof 128,128,128, and they are soldered to the pre-position (the left corner segment position of front side) of above-mentionedsubstrate 104, and are installed in the front side left comer portion of substrate 104 (referring to Fig. 4 and Figure 17).In addition, electronic device part (referring to Fig. 7) such as integrated circuit (IC) chip 103 etc. has been installed inpre-position substrate 104 rear sides, thatbattery side terminals 120 are not installed.

Thereby, battery unit 102,102 arrives together according to the combinations of states that front and back are aligned to row, and connecting above-mentionedsubstrate 104 at the top of twobattery units 102, devices (referring to Fig. 4) such as describedbattery side terminals 120, IC chip 103 are installed onsubstrate 104.

Then, the battery unit 102,102 that has connectedsubstrate 104 on it is inserted into theback cover 106 from the right side.At this moment,battery side terminals 120 just are inserted into therectangular slits 108 of back cover 106 (referring to Fig. 7) from the right side cunning.

Then, as described above, the slide protrusion part 129,129 ofbattery side terminals 120 is inserted in the sliding tray 117,117 of back cover 106 (referring to Fig. 7).

At last, by being combined,fore shell 105 andback cover 106 sealed two battery units 102 (referring to Fig. 8).

At this moment, projection 118,118 on thefore shell 105 engages with grooving 130,130 on theback cover 106, and meanwhile, terminals pressurizationfin 116 is pressed on the right surface of terminals shell 121, is exposed at base component 127,127,127 at right surface on eachterminals member 122 thereby sealed.Then,battery side terminals 120 are carried out the orientation of left and right directions, andbattery side terminals 120 are remained betweenback cover 106 and thefore shell 105.

The method of utilizing ultra-sonic welded connects together the opening periphery offore shell 105 with the opening periphery ofback cover 106, thereby finished combining of fore shell and back cover.In addition, also can be that method with bonding agent rather than ultra-sonic welded connects two and half housings.

As described in just,battery pack 100 is by three parts, andback cover 106, battery unit 102 (comprising devices such asbattery side terminals 120, substrate 104) andfore shell 105 constitute by this way: three parts are assembled into together along a direction.

Below, will describe combining of mainbody side terminals 30 and above-mentionedbattery side terminals 120 in detail.

At first, mainbody side terminals 30 are set on the above-mentioned position and (promptly are positioned at the position, preceding turning of bottom surface one side), and it comprises: three wiringelement 31,31,31, and they are from thebottom surface 15 and the inner surface 13a projection of upperledge support body 13; Two guidingpieces 32, they are being clipped in threewiring element 31 between them on the fore-and-aft direction; Be arranged on the baffle on the upperledge support body 13 rotationally, it covers the upper surface (referring to Figure 22 and 23) of eachwiring element 31,31,31.

When fore-and-aft direction is observed,wiring element 31 is the flat plate of rectangle, and its top edge and left hand edge are embedded in the upperledge support body 13, onelead portion 34 is outstanding (referring to Figure 24) from upperledge support body 13, the part of exposing from upper ledge support body 13 (being lower limb and right hand edge) is ascontact portion 35, thiscontact portion 35 is clamped between two contacts 125,125 of above-mentionedbattery side terminals 120, and the end edge chamfering ofwiring element 31 is handled.

It is identical with the interval that is provided with between the groove 124,124,124 of terminals on the above-mentionedbattery side terminals 120 that interval between three wiringelement 31,31,31 is designed to, and the thickness of eachwiring element 31 is made into to be about half (referring to Figure 22 and 23) that the terminals that are formed in thebattery side terminals 120 are provided with the width ofgroove 124.

When fore-and-aft direction is seen, guidingpiece 32 is a rectangle, and is similar with the shape of above-mentionedwiring element 32, and and theupper frame 13 of battery loading station andbottom surface 15 form as one (referring to Figure 24).

In addition, be provided with two guidingterminals 32,32, when when fore-and-aft direction is observed, guidingterminals 32 are greater than thecontact portion 35 ofwiring element 31, and the plate thickness of guidingterminals 32 is also greater than the thickness of wiring element 31.In addition, it is identical with interval between two guiding grooves 123,123 made on the above-mentionedbattery side terminals 120 that the interval of guiding between theterminals 32,32 is made into, the thickness of slab of each guidingpiece 32,32 is formed less than the width of the last guiding groove 123,123 of the terminals housing 121 of above-mentionedbattery side terminals 120, and (referring to Figure 23) handled in the end edge chamfering of guidingpiece 32.

As mentioned above, because guidingpiece 32 is made into to be slightly larger than thecontact portion 35 ofwiring element 31, so when mainbody side terminals 30 will soon combine withbattery side terminals 120, beforecontact portion 35 entered intoterminals groove 124, guiding piece entered in the guidinggroove 123 of guiding piece 32 (referring to Figure 26) first.

The Support Position ofbaffle 33 is close to the open side edge (right side edge) of upperledge support body 13 inner surfaces (being lower surface) leading section, thereby can freely rotate (referring to Figure 24 and 25) on above-below direction.

Specifically; be shaped on theprotection framework 13b of a convex in the front end of upperledge support body 13 inner surfaces (lower surface); and the place, both sides of the edge, front and back atbaffle 33 is shaped on twoledges 36,36 as back shaft integratedly; be used for engaging rotationally, arranged awind spring 37 around backshaft ledge 36 with the left and right sides two end portions of above-mentioned protection frame part 13b.When from the back when observing, baffle 33 is actuated (referring to Figure 24 and 25) in the counterclockwise direction.

Partly locate to be provided withrotational stop part 38,38 (only having represented one of them stop portion in the drawings) at the rotating fulcrum ofbaffle 33; it contacts with upperledge support body 13; be used to stop above-mentioned rotating counterclockwise; whenbaffle 33 was in left the state of below deflection (being essentially 45 °), baffle was in the end (referring to Figure 10 A, 24 and 29) of the rotational travel when rotating counterclockwise.In addition, the rotational travel end whenbaffle 33 clockwise rotates is positioned at such position: baffle 33 is accommodated in thebaffle holding portion 13b place of upperledge support body 13, and is in horizontal attitude (referring to Figure 10 B) basically.

Baffle 33 is in the distance of the undersized on the fore-and-aft direction between above-mentioned two guidingpieces 32,32, thereby is made into can rotate between two guidingpieces 32,32 all the time.With above-mentionedwiring element 31 corresponding positions, be shaped onslit 39,39,39 on thebaffle 33, these slits are to the rim openings of rotating end one side.As a result, whenbaffle 33 upwards rotated, eachwiring element 31,31,31 will be inserted in theseslits 39,39,39, thereby made thatbaffle 33 is rotatable, simultaneously, madewiring element 31,31,31 expose (referring to Figure 10,22 and 23).Incidentally, what Figure 10 A represented is the state of baffle after rotation, and Figure 10 B then represents is the state of baffle when not rotating.

Then, when applying external force in the counterclockwise direction on the rotation end atbaffle 33 not, the corner part between two guidingpieces 32,32 just is in such state: they are blocking the both sides (referring to Figure 25) that baffle 33 rotates end margins.In addition, under this state, the turning of thecontact portion 35,35,35 of above-mentionedterminals 31 is in the state (referring to Figure 25) that engages with above-mentionedslit 39,39,39.

Then; as will be described in detail; whenbattery pack 100 is installed to battery when packing in thepart 10; the terminals housing 121 ofbattery side terminals 120 will the above-mentionedbaffle 33 of roof pressure; make it overcome the elastic force ofhelix torsion spring 37 and clockwise rotate, and finally be positioned at the position (referring to Figure 29) of thebaffle receiving portion 13b of upperledge support body 13.

The result: thecontact portion 35,35,35 of mainbody side terminals 30 is exposed, and the terminals that relatively enter into terminals housing 121 are provided with groove 124,124,124, thereby be sandwiched in each between the contact 125,125,125, set up thus and electrically contact (referring to Figure 28).

In the above described manner, whenbaffle 33 is in the state that is not subjected to the external force effect because it coverscontact portion 35,35,35, thus contact portion do not expose, thereby can prevent that foreign matter from bonding to (referring to Figure 25) on the contact portion.

In addition, when on mainbody side terminals 30 parts, any type of collision having occurred, for example, whenbattery pack 100 is packed into the location of mistake (mistake is packed into), then just have such possibility: other member impacts outside thebattery side terminals 120 is to mainbody side terminals 30.

Even under these circumstances,, act on the guidingpiece 32 so external force is actually, but not act on thecontact portion 35, thereby can prevent thatcontact portion 35 from deforming because guidingpiece 32,32,32 is made into greater thancontact portion 35.

In addition; when less relatively foreign matter strikes on the mainbody side terminals 30; owing to be provided with above-mentionedbaffle 33; so foreign matter is clashing intobaffle 33 earlier before mutually with wiring element 31 (contact portion 35) collision; so external force has been subjected to buffering, thereby contactportion 35 can directly not be subjected to very big external force effect.

In addition; as mentioned above; since when whenbaffle 33 applies the external force with fore-and-aft direction component, baffle 33 is in the state that is sandwiched between two guidingpieces 32; because guidingpiece 32,32 is in order to supportbaffle 33; and because three contact portions are inserted in threeslits 39,39,39; so external force acts on threecontact portions 35,35,35 byslit 39,39,39 respectively, thereby can prevent thatbaffle 33 is shifted on fore-and-aft direction.Therefore, owing to external force can not act on thecontact portion 35 all the time, so, in this regard, can prevent thatcontact portion 35,35,35 from deforming.

Incidentally, in the above embodiments, mainbody side terminals 30 have: be formed on the guidingpiece 32,32 on the upper frame body portion; By integrally formed threewiring element 31,31,31 of embedded mould pressing method or rotating baffle 33.Perhaps, mainbody side terminals 30 have in the substrate of reservation shape molded or form the various piece of another element, thereby this substrate is connected on the upperledge support body 13 as terminals.

Next will describe: whenbattery pack 100 was loaded into battery and packs in thepart 10, howbattery side terminals 120 were connected with mainbody side terminals 30.

At first, thebattery pack 100 that has battery side terminals 120 (it comprisesterminals location rib 109 and terminals pressurization fin 116) is located by deflection, thereby can be driven intooverhang 17 belows of upperledge support body 13, like this, mainbody side terminals 30 andbattery side terminals 120 each other over against.

Next, whenbattery side terminals 120 are driven into the below of above-mentioned overhang 17 (referring to Figure 13), the guidingpiece 32,32 of mainbody side terminals 30 is just relatively inserted in the guiding groove 123,123 of battery side terminals 120 (referring to Figure 26).At this moment, because the chamfering processing of the open side edge of guidinggroove 123, and the also chamfering processing of the end edge of guidingpiece 32, so be easy to the two is combined.

Under this state, guidingpiece 32,32 is in the state that is inserted into slightly in the guiding groove 123,123, and the result has realized the location ofbattery side terminals 120 with respect to main body side terminals 30.As mentioned above, before contact 125,125 andcontact portion 35,35,35 came in contact, the guiding piece of being made up of moldedcomponents 32,32 engaged with guiding groove 125,125, so just can finish the location by making accurate member.Therefore, before the contact 125,125 of twoterminals 120,30 andcontact portion 35 are in contact with one another, the location that just can accurately finish twoterminals 120,30, the result,contact portion 35 is contacting with very high precision subsequently withcontact 125.

From this state, the lower part ofbattery pack 100 rotates, and packs in thepart 10 thereby be encased in battery.Caught by above-mentionedoverhang 17 by the lock portion for the treatment of that makes backcover 106, and distinguish as rotating fulcrum, carry out the rotation (referring to Figure 14) ofbattery pack 100 with this.

Then, the terminals that thecontact portion 35 of mainbody side terminals 30 is insertedbattery side terminals 120 relatively are provided with (referring to Figure 27) in thegroove 124, contact portion contacts with twobump contact part 125a, 125a, and they are pushed open, thereby make contact 125,125 that elastic bending take place, and clamping contact portion 35.As a result, betweenbattery side terminals 120 and mainbody side terminals 30, set up and be electrically connected (referring to Figure 28).

In addition, position relation betweencontact portion 35 and the contact 125,125 is as follows:contact portion 35 is relatively moved along its surface direction, and, since two contacts 125,125 take place the mode of elastic bendings end portion (beingbump contact part 125a, 125a) is open and mutually away from and the power that acts between two contacts can be not excessive, socontact portion 35 and contact 125,125 can not be out of shape all the time.

In addition, because it is as follows that the position betweenbattery side terminals 120 and the mainbody side terminals 30 concerns: at the terminals of the both direction upper shed ofbattery side terminals 120 groove 124,124,124 is set and contacts with the flattabular contact portion 35,35,35 that the bight is approximately the right angle, sobattery side terminals 120 can combine with mainbody side terminals 30 in the direction scope of 90 degree, direction scope wherein comprises left and right directions and above-below direction.

That is to say, when only considering the structure ofbattery side terminals 120 and mainbody side terminals 30,battery side terminals 120 can be from left-hand, below or the left side that comprises above-mentioned direction tiltedly below and mainbody side terminals 30 to combining, this means: the former can roughly in any direction combine with the latter in 90 scopes of spending, in addition, in any combination of carrying out with these directions, can not act on too big power oncontact portion 35 and contact 125,125, the result is thatcontact portion 35 and contact 125,125 can not be out of shape all the time.

Certainly, in the above-mentionedbattery pack 100 and the battery ofcamera body 2 are packed the relative position relation ofpart 10 into, becausebattery side terminals 120 will combine with mainbody side terminals 30 along direction substantially left, so, we can say that thebattery side terminals 120 and the structure of mainbody side terminals 30 can not play one's part to the full.

But, owing to above-mentionedbattery side terminals 100 are packed in the mainbody side terminals 10 by rotating, thereby, twoterminals 130 and 30 combination are not only to be a durection component on the direction, by adopting terminal structure, just can think that twoterminals 120 and 30contact portion 35 and contact 125,125,125 are subjected to too big active force at the Shi Buhui that mutually combines, so can not produce distortion.

In addition, becausebump contact part 125a, 125a are arranged on the portion slightly of contact 125,125, therefore, bumpcontact part 125a, 125a can contact withcontact portion 35, also have such possibility: two terminals are bonded to each other in 90 degree direction scopes, and this direction scope comprises above-mentioned both direction.

That is to say,contact portion 35 enters between the contact 125,125, and they are promoted to sidepiece, thereby make they mutually away from, but, because 35 of contact portions contact withbump contact part 125a, 125a, thus though two terminals the 120, the 30th, any direction in 90 degree scopes is carried out combination, thebattery part 10 of packing into can both be admittedbattery pack 100 in an identical manner, and 90 ° of direction scopes wherein comprise above-mentioned both direction.

In addition, becausebump contact part 125a, 125a are set on the taper of contact 125,125, so even contact 125,125 andcontact portion 35 have displacement slightly in the position of fore-and-aft direction, also can guarantee to have firm annexation between two terminals (contact 125,125 and contact portion 35).

Below, for the marriage relation betweenterminals 120 and 30, the material and the width that can influence theterminals member 122 of contact condition betweencontact 125 and thecontact portion 35 are discussed.

In addition,wiring element 31 usefulness brass are made (thickness t=0.35mm), and its contact portion has been plated the thick gold of 0.76 μ m.In addition, select brass to be as the reason ofcontact 31 manufactured materialss why: brass, phosphor bronze and beryllium copper are used to make the contact usually, and have also considered the requirement of cost and machinability aspect.

In addition, gold-plated for wherein, with one deck nickel as basic unit, and considering needs to improve safety ratio, and the thickness of setting nickel dam is 0.75, wherein, the reason of considering safety ratio is: under the user mode ofbattery pack 100 andvideo camera 1, need insert and extractbattery pack 100 continually.

Thereby even above-mentioned design is used on the terminal structure ofvideo camera 1 andbattery pack 100,bump contact part 125a also can during normal use tolerate the abrasion of Gold plated Layer fully.

In addition, mainly be in contact portion, promptly the thick gold of 0.76 μ m has been plated atcontact portion 35 places, and inlead portion 34, the thickness of Gold plated Layer is recommended as 0.1 μ m.This is to have stable electrical connection in order to ensure the two.

Thereby, forterminals member 122, can after testing, from four kinds of samples, choose a kind of.As mentioned above,, considered three kinds of materials (brass, phosphor bronze and beryllium copper), but also considered the elastic force of contact 125,125, because the characteristic of phosphor bronze and beryllium copper is comparatively favourable, so they are tested for the material that will test.

1. sample adopts is phosphor bronze (thickness t=0.2mm), and on contact portion, electroplated the thick gold of 0.76 μ m, the material that 2. sample adopts is a phosphor bronze (thickness t=0.2mm), and on contact portion, electroplated the thick gold of 0.76 μ m, the material that 3. sample adopts is a beryllium copper (thickness t=0.2mm), and electroplated the thick gold of 0.76 μ m on contact portion, and the material that 4. adopts of sample is a beryllium copper (thickness t=0.15mm), and electroplated the thick gold of 0.76 μ m on contact portion.Incidentally, as for gold-plated, under the situation of above-mentionedterminals member 122, also adopted nickel dam as basic unit.In addition, the reason that why golden layer thickness is chosen as 0.76 μ m also is identical.In addition, the gold plating thickness on the contact 125,125 is identical with contact portion, also is that 0.76 μ m is thick, that is to say, the gold plating thickness of bump contact part 125,125 also is 0.76 μ m, and the gold plating thickness on the lead-inwire part 128 then preferably is no more than 0.1 μ m.

As for method of testing wherein, execution be the durability fatigue test, this test in,wiring element 31 by fromterminals member 122 plug 7000 times.

Test event relates to contact impedance, total engaging force, total tearaway load and visual examination, and first three test event is represented as the numerical value when pre-determined number, and number of times wherein is from 1 to 7000.In addition, visual examination is after having plugged 7000 times endurance test, carries out with the method for visual observation.

In addition, utilize four-end method (4-terminal) to measure contact impedance, in this method of measurement, open circuit voltage is set as and is not more than 20mV, and short circuit current is set as and is no more than 100mA, and the setting of resistance is 20m Ω_Max

Byterminals 120 are engaged (combination), engaging force is measured total engaging force withterminals 30, this engaging force is set to 10N (newton)_Max

As for total tearaway load, be the active force that records when being thrown off that engages betweenterminals 120 andterminals 30, this tearaway load is set to 0.3N (newton)_Min

The result of the test of above-mentioned three pilot projects is illustrated in Figure 31 in Figure 33.

For sample 1., the dispersion degree of contact impedance little and stable (referring to Figure 31) is inserted, withdrawal force is also very stable, thereby has obtained good numerical result (referring to Figure 32 and 33).In addition, visual examination shows that thebump contact part 125a of contact 125,125, the wear extent of 125a are suitable, and does not find any phenomenon that goes wrong.

For sample 2., in number of times was 7000 endurance test, the dispersion degree of contact impedance was big, and total engaging force also weak (referring to Figure 32).In addition, a spot of scraping vestige has been found in visual examination.Be also noted that: total engaging force is attenuated to a certain degree, makes that contact pressure is very little, thereby contact impedance has been caused influence.

For sample 3., contact impedance and total engaging force be without any problem, but tearaway load alters a great deal, so when throwing off, the so-called sense of beating will occur.In addition, visual examination is found: tearaway load changes more greatly, and the abrasion scraping that takes place onwiring element 31 is just serious more, and wearing and tearing have taken place thebump contact part 125a on thewiring element 31.

For sample 4., total engaging force is very weak, and contact impedance is relatively stable, but is implying such possibility: the numerical value of contact impedance can go wrong.In addition, visual examination finds that total engaging force is more little, and the quantity of abrasion scraping vestige is just few more.

The result shows: in these four kinds of samples, 1. sample is only.

In addition, for beryllium copper, carrying out on the beryllium under the gold-plated situation, having only so-called back depositing process (promptly carrying out plating after making reservation shape again) is feasible (and other technology all is difficult), and why Here it is will selectsample reason 1..

That is to say, beryllium copper normally is being difficult to after gold-plated process and be shaped (for example bending and compacting technologies such as crimping), thereby, in the situation of above-mentionedterminals member 122, at it processed and be shaped after, its shape makesbump contact part 125a, 125a be in contact with one another.The result: when any object with such contact portion being carried out when gold-plated, by the back depositing process, contact portion when contacting with each other by gold-plated.

Meanwhile, for four kinds of above-mentioned samples, they all satisfy above-mentioned setting (is contact impedance: 20m Ω_MaxEngaging force: 10N_MaxTearaway load: 0.3N_Min),, thereby, as select in these samples any one, any problem can not appear.But, if consider worse situation, because the 1. resulting result of the test of sample is fine, so preferentiallyselect sample 1..

In addition, 1. be the material ofterminals member 122 if select sample, then to consider the contact pressure that elastic force produced (referring to Figure 34 to 36) of wiring element 125,125.

Before this, the terminals of at first describingterminals member 122 and this member place are provided with the parameters such as size (referring to Figure 34 and 35) ofgroove 124 with will be clear that.

As mentioned above, the thickness of the wiring element 125,125 ofterminals member 122 is 0.2mm, width is 1.2 millimeters, and the length of the part that exposes outside from inlet part is 3.9 millimeters, and radius r=0.3 of above-mentionedbump contact part 125a, 125a, its position is: its center is offset 0.45mm (referring to Figure 34 and 35) from the edge ofbase component 127 to base component 127.In addition, wiring element 125,125 extends to close mutually from inlet part, and they are bent into: longitudinally approximately center position become and be parallel to each other, and between from the bending part to the marginal portion, the spacing distance of the two is always 0.6 millimeter.As a result, zero contact (referring to Figure 21) each other between twobump contact part 125a, the 125a.

The A/F that terminals are provided withgroove 124 is made into 0.45mm, and the thickness of slab t of above-mentionedcontact portion 35 is 0.35mm, therefore, whencontact portion 35 is inserted into terminals when being provided with in thegroove 124 with standard attitude (centre position), inward flange and the gap between thecontact portion 35 thatgroove 124 is set at terminals are ((0.45-0.35)/2=0.05mm) (referring to Figure 34 and Figure 35).

At this moment, the flexural deformation that two contacts 125,125 take place is basic identical, and displacement is 0.175mm.In addition, Ci Shi contact pressure is 1.0091N (referring to Figure 36).

Then, whencontact portion 35 is inserted into terminals when being provided with in thegroove 124 with the state that is offset on certain direction, it is maximum that the displacement of acontact 125 reaches, and the displacement of anothercontact 125 then is minimum, causes the contact pressure of this moment to become 1.4416N and 0.4609N respectively.

Thereby, adopting saidsample 1. under the situation of material (being phosphor bronze), whencontact portion 35 contacted withbump contact part 125a, the maximum that can observe contact pressure was that 1.4416N, minimum value are 0.4609N, as contact pressure, these two values are all enough.

Carrying out under the gold-plated situation, 0.0981N is enough usually to the contact pressure of 0.1961N, but saidsample 1. in, the contact pressure that is applied is greater than this above-mentioned value, this seems, and some is unnecessary.

But, because this terminal structure is based on such prerequisite: betweenbattery pack 100 andvideo camera 1, electrically contact, thereby be easy to estimate that it is very big to insert/extract number of times, so Gold plated Layer is worn.

Thereby, under the situation that Gold plated Layer is worn,, must guarantee that the numerical value of contact impedance is in the setting scope even expose as the nickel dam of basic unit.

Thereby, when the contact pressure of nickel dam is generally 0.5884N, owing to can guarantee contact impedance value up to specification, thereby, although the contact pressure of acontact 125 reaches above-mentioned minimum value 0.4609N, can reach maximum 1.4416N by the contact pressure that guarantees anothercontact 125, even just can under the situation that Gold plated Layer is worn, also can satisfy the numerical value (referring to Figure 36) of regulation.

In addition, also with insulation impedance and withstand voltage test event as other, the test result of above-mentioned four kinds of samples and is not observed any special difference all in the setting scope.

In addition, as for anti-environmental performance, launched the test of electric property and mechanical performance at moisture resistance, temperature cycles and the situation that sprays salt solution, the result does not find to exist between each sample special difference.

Subsequently, in the above-described embodiments, be as example with the battery pack 100 (device to be installed) that hasbattery side terminals 120 and video camera 1 (body side equipment) with mainbody side terminals 30, but also can be with thedry cell batteries 140 that also hasbattery side terminals 120 as battery pack 100 (device to be installed), and flash lamp for photography 150 andbattery charger 160 and video camera be 1 the same, also have main body side terminals 30 (referring to Figure 37 to 40).

In addition, forbattery pack 100, there is multiple model, and forvideo camera 1, also is divided intopermission charge type 1A and do not have the not rechargeable type 1B (referring to Figure 37 to 40) of charge function with charge function according to the difference of capacity.

If all various devices (multiple battery group 100,dry cell batteries 140 etc.) can both be loaded in the equipment (video camera 1 (comprise and allowcharge type 1A and non-rechargeable type 1B), shooting etc. 150 and battery charger) with main body side terminals, then will go wrong.

For example,dry cell batteries 140 can be loaded among the video camera 1B (non-charging type), but dry cell batteries definitely can not be encased invideo camera 1A (charging type) and thebattery charger 160, in addition, for flash lamp for photography 150, in the situation of high-performance tailored version flash lamp for photography 150A, the high-capacity battery settype 100H in the battery pack of can only packing into 100, and do not allow to pack into the low-capacity batteries group 100L of other model, thebattery pack 100S and thedry cell batteries 140 of normal capacity.

Herein, allow on the chargetype video camera 1A direct current electric jack joint (DC in jackterminal) to be housed, if the DC jack is connected, then just can be by charging with actuated cameramain body 2 to being encased in thebattery pack 100 that battery packs in thepart 10, and described non-charging type 1B is the equipment that does not have charge function.Incidentally, the video camera of enumerating in the foregoingdescription 1 belongs torechargeable type 1A, and above-mentioneddry cell batteries 140 does not allow to be encased in thisvideo camera 1.

Thereby, just need judge whether battery pack 100 (although it has battery side terminals 120) can be loaded in the equipment with mainbody side terminals 30, thereby judging when not allowing to pack into, can prevent to pack into mistakenly.

Thereby, near above-mentionedbattery side terminals 120, being provided withdifference label 111, near place, the corresponding region mainbody side terminals 30 is provided with above-mentioned blockedportion part 19 simultaneously, is used to stop packing into ofbattery pack 100 devices such as grade.

Hereinafter will the concrete example of the blockedportion part 19 of thedifference label 111 ofbattery side terminals 120 and mainbody side terminals 30 be described.

As for the various difference labels 111 on thebattery side terminals 120, there be four types on L type, H type S type and D type, Ltype difference label 111L is applicable to thebattery pack 100L of low capacity, S type difference label 111S is used on thebattery pack 100S of standard model, Htype difference label 111H is used on thebattery pack 100H of high power capacity, and Dtype difference label 111D then is applicable to dry cell 140 (arriving Figure 40 referring to Figure 37).

In addition, various blockedportion parts 19 for mainbody side terminals 30, there be four types on I type, II type, III type and IV type, I type blocked portion partly is applicable to and allows chargetype video camera 1A (and battery charger 160), II type blocked portion partly is used on the video camera 1B that does not allow to charge, III type blocked portion partly is used on the special-purpose flash lamp for photography 150A of high-performance, and IV type blocked portion part then is used in low performance flash lamp forphotography 150B and goes up (arriving Figure 40 referring to Figure 37).

The S type difference label 111S that is used on the normalcapacity battery pack 100S has above been described, it has littleoutstanding bar 110, outstanding bar is made into from the left end ofterminals location rib 109, extends along opposite direction (on the fore-and-aft direction), andlocation rib 109 is formed in the position (referring to Figure 37 to 40) that is offset from theback side 106a ofback cover 106 slightly to the right.

The Ltype difference label 111L that is applicable to low-capacity batteries group 100L is made into such structure: the littleoutstanding bar 110 onterminals location rib 109 left ends of above-mentioned S type difference label 111S extends to the back side ofback cover 106 106a, thereby the little outstanding bar L of Ltype difference label 111L is made into theback side 106a one (referring to Figure 37 to 40) withback cover 106.

The Htype difference label 111H that is applicable to high-capacity battery group 100H is such: as above-mentioned S type difference label 111S and Ltype difference label 111L, be not shaped in the opposite direction (fore-and-aft direction) and go up littleoutstanding bar 110, the 110L (referring to Figure 37 to 40) that extends.

The Dtype difference label 111D that is applicable todry cell batteries 140 is such: as Htype difference label 111H, do not make little outstanding bar 110,110L from the left end ofterminals location rib 109, but make adifference fin 141 that extends integratedly to the right from the central part ofterminals pressurization fin 116,pressurization fin 116 wherein (arrives Figure 40 referring to Figure 37) onfore shell 105.

Below, will partly be that the process how to combine with above-mentioned various difference labels 11 is described to the structure and the various blocked portion of each blockedportion part 19.

At first, an I type blocked portion of mainbody side terminals 30 partly is used among thevideo camera 1A (rechargeable type 1A) of the foregoing description, this blocked portion partly is to be made ofoverhang 17 on the upperledge support body 13 of mainbody side terminals 30 and the above-mentionedoutstanding bar 18 of blocked portion, andoutstanding bar 18 wherein is made into to extend (referring to Figure 37) left from the rear end ofoverhang 17.

In this I type blocked portion part, because thedifference fin 141 of the middle body ofoverhang 17 and Dtype difference label 111D interferes, the D type power supply so can not pack into, but for other L, S and H type difference label, because the eaves shapepart 17 at place, their middle parts can not interfere withdifference label 111, so allow to pack into.

Therebydry cell 140 can not be loaded among the chargetype video camera 1A that has I type blocked portion part, thereby, just can prevent the trouble of being packed into and bringing by mistake owing to dry cell resistance 140.On the other hand, no matterbattery pack 100L, 100S, 100H of having adoptedother difference label 111L, 111S, 111H their capacity height then all can be loaded into battery pack into (referring to Figure 37) in thepart 10.

Under the situation of II type blocked portion part, be shaped on one in the central position ofoverhang 17 and cut part 17a, the result, becauseoverhang 17 can not interfere withdifference label 141, so allow the difference label to insert, meanwhile, do not have on the overhang any and other typearea distinguishing label 111S, 111L, 111H interference part, sodifference label 111L, 111S, the 111H of all these types can both be inserted into (referring to Figure 38).

Thereby all low-capacity batteries group 100L, normalcapacity battery pack 100S, high-capacity battery group 100H anddry cell batteries 140 can both be loaded among the non-charge type video camera 1B that has II type blocked portion part (referring to Figure 38).

Electronic equipment 300 is provided with a housing 301, it has a spatial accommodation, the size in this space is measure-alike with above-mentionedbattery pack 201 basically, and on direction backward, has a perforate, on the edge of this back side perforate, be provided with a blocking element 310, be used for preventing that thebattery pack 201 of packing into from deviating from from the inside of above-mentioned housing 301, the inside of housing 301 is as the battery part 302 (referring to Figure 44) of packing into.

On the battery of housing 301 is packed the inner face (front end face) of part 302 into, be provided with main body side terminals 303, its with above-mentionedbattery pack 201 oncell terminal 206 corresponding (referring to Figure 44).

In the lower right-most portion of housing 301 back side perforates, be provided with a blocked portion jut 304, it is made into to be substantially equal to or to be slightly less than the cross-sectional structure (referring to Figure 49,50 and 51) ofmistake proofing tankage 210 on the above-mentionedbattery pack 201.

Like this, whenbattery pack 201 is packed battery into when packing in the part 302 according to normal orientation, above-mentioned blocked portion jut 304 will be arranged in themistake proofing tankage 210 ofbattery pack 201, allows the sliding battery pack into (referring to Figure 51 and 52A) in the part 302 that is inserted into ofbattery pack 201 thus.

Blocking element 310 is made of a locking rod 311 and an actuation gear 312, when when the angle of overlooking is observed,shank 31 be shaped as the L shape, actuation gear 312 is used for locking rod 311 tops to locking direction (referring to Figure 49 and 50).

Specifically, locking rod 311 comprises one a long-armed 311a and a galianconism spare 311b, wherein long-armed is the part of the openend of housing 301 right flanks, galianconism spare then stretches out left from the rear end of locking rod, the leading section of long-armed 311a is supported on the housing 301 rotationally by a rotating shaft, and rotating shaft is extended (referring to Figure 49 and 50) at above-below direction.

One sheet metal member can be bent into the U type and form above-mentioned actuation gear 312, and parts of actuation gear 312 are fixed on the member of above-mentioned housing 301 1 sides, another parts then with the right surface elasticity of long-armed 311a of above-mentioned locking rod 311 contact the result: on the direction opposite, impel locking rod to rotate with clockwise direction in Figure 49 and 50.

In addition, be actuated and the locking rod 311 that rotates is stopped by a rotary stop device (not shown) and no longer rotates, under by the state of blocked portion, the part (referring to Figure 50) of the back side perforate of the galianconism spare 311b covering shell 301 of locking rod 311.

Thereby, for the battery thatbattery pack 210 is encased in electronic equipment 300 is packed in the part 302, the effect that need overcome actuation gear 312 makes on above-mentioned locking rod 311 clockwise direction in the drawings rotates, thereby make galianconism spare 311b avoid pack into the back side perforate (referring to Figure 49) of part 302 of battery, then the sliding battery that is inserted into ofbattery pack 201 is packed in the part 302.

As mentioned above, at this moment, be in conventional orientation inbattery pack 201, promptly mistake proofingtankage 210 is positioned under the situation in the lower right corner (referring to Figure 52 A), and above-mentioned blocked portion jut 304 is arranged inmistake proofing tankage 210, inserts thereby allowbattery pack 201 to slide.In addition, when battery pack slides into battery and packs the bottom of part 302 into,cell terminal 206 is connected with main body side terminals 303, and locking rod 311 rotates on the direction opposite with clockwise direction, make its galianconism spare 311b be pinned, thereby prevent thatbattery pack 201 from deviating from (referring to Figure 50) from battery is packed part into by the rear end face ofbattery pack 201.

In addition, whenbattery pack 201 was not in conventional orientation, pack into the blocked portion part 304 of part 302 of above-mentioned battery interfered withbattery pack 201, thereby stoped the insertion (referring to Figure 52 B, 52C, 52D) of battery pack.

That is to say, for example, when the fore-and-aft direction ofbattery pack 201 is located correct but is turned upside down (referring to Figure 52 B), owing to mistake proofingtankage 210 is not set at the position, the lower right corner ofbattery pack 201, the blocked portion jut 304 of part 302 will be interfered with this lower right corner part so battery is packed into, thereby,battery pack 201 can not be inserted into battery and pack in the part 302.

In addition, in that the above-below direction ofbattery case 201 location is correct but under the situation that fore-and-aft direction is put upside down (referring to Figure 52 C), perhaps (referring to Figure 52 D) under the situation that all put upside down the location of above-below direction and fore-and-aft direction, becausemistake proofing tankage 210 is not positioned at the place, the lower right corner ofbattery pack 201, the blocked portion jut 304 of part 302 will be interfered with this lower right corner part so battery is packed into, thereby,battery pack 201 can not be inserted into battery and pack in the part 302.

By this way, whenbattery pack 201 is not in conventional orientation, because being capped pack into the blocked portion jut 304 of a part of part 302 back side perforates of battery,battery pack 201 stops, sobattery pack 201 can not be inserted into battery packs in the part 304, even insertion very slightly also is impossible, this just can point out the user immediately: the wrong court of thebattery pack 201 that will pack into.The result is: packed in the part 304 evenbattery pack 201 can slightly be inserted into battery, can prevent that also the user from packing battery pack into by force under the directed incorrect situation of battery pack.

In addition, in the battery pack relevant 201 with the foregoing description, illustrated is with pack into thebattery case 202 of square box shape of thebattery unit 203 of square rod shape, but the present invention is not limited to this, and this just means: the columned battery unit of can packing in thebattery case 201 of square rod shape.In brief, as long as the shape approximation of battery case is the square rod shape, promptly just can use the present invention.

In addition, in for the battery pack relevant 201 with the foregoing description,mistake proofing tankage 210 is formed in the total length setting of glide direction upperedge battery case 202, but the present invention is not limited thereto, this just means: the mistake proofing tankage can be made and extend to the end face that inserts a side, but the length on glide direction differs and is decided to be the total length of battery case.In the case, when battery pack was packed into mistakenly, the blocked portion jut that is positioned at electronic equipment one side can prevent to insert battery along pointing to pack into the direction of part 302 bottoms of battery.

In addition, in for the battery pack relevant with the foregoingdescription 201, illustrated is with the bight office ofmistake proofing tankage 210 built inbattery case 201, but the present invention is not limited thereto, and this just means: can be withmistake proofing tankage 210 on the side of battery case 201.In such a manner, by makingmistake proofing tankage 210 in certain position, even then the battery pack that will pack into both turned upside down, also put the cart before the horse, also can prevent from battery pack is packed into mistakenly, position wherein is meant: from the center width position of the side that will make the mistake proofing tankage thereon to the position of end side skew.

From above description as can be seen, according to battery pack of the present invention battery pack so: it has the battery electronic equipment of part this electronic equipment of packing into of packing into by sliding to, this battery pack is characterised in that: it has the battery case that is roughly the square rod shape, and on an end face on the glide direction, be provided with cell terminal, and on the part of battery case one side, make a mistake proofing tankage along the glide direction extension, side wherein is the surface of other the both ends of the surface on glide direction.

Thereby, according to battery pack of the present invention, owing to be asymmetric when glide direction is observed at a plurality of location points, thereby, utilize this feature just can be limited to the relative battery of the electronic equipment one side unique orientation partly of packing into.

As a result, when battery pack was in the orientation different with this routine orientation, it can not be inserted into the battery part of packing into, thereby prevents that battery pack from being packed into mistakenly.

In addition, owing to be under the situation of normal location cell terminal packed in the battery part of packing into, the problem of bringing so can prevent the terminals mistake of the terminals of electronic equipment one side and battery pack one side from must contact with each other.

In addition, in the present invention because the structure that is contained in the battery unit in the battery case is designed to the square rod shape, thus for square battery case, do not have the space to be wasted, no matter thereby overall size how, can both make battery pack have very big capacity.

In the present invention, since above-mentioned mistake proofing tankage by along the glide direction of battery case built in the office, bight, thereby can between battery case and battery unit, form predetermined space, and this space can be used to arrange the negative side butt strip that extends around battery unit, thus improve space availability ratio.

In the present invention, owing to be set on the side from the extended negative side butt strip of the battery tube bottom of battery unit, and on this side, be shaped on the mistake proofing tankage, butt strip has been avoided the mistake proofing tankage, so do not have space waste, no matter thereby overall size how, can both make battery pack have very big capacity.
