The change-over plug for travel of safetyTechnical field
The present invention relates to a kind of change-over plug for travel, it is also referred to as " travelling converter " herein.Using this converter,The attaching plug of a certain (country) standard can be inserted into the power outlet of Reiseziel.For this purpose, the travelling conversion plugHead needs the socket of the first standard and the attaching plug of another standard.In this application, more precisely, be related to it is a kind of can insertEnter the change-over plug for travel of at least power outlet of the first standard and the second standard.In addition, can in the change-over plug for travelTo select an attaching plug for using the first standard and the second standard.
Background technique
When global tourism and trade increasingly increase, such change-over plug for travel is just more and more usedOr travelling converter.It is therefore desirable to which the travelling of the power outlet for being suitable for several various criterions that is small-sized, being easy to carry about with one turnsInsert head.
101872911 A of Chinese patent application CN discloses a kind of travelling converter with substantially round shell.Power supplyPlug is placed in the enclosure interior and can remove the shell.In this way, can be used at least three kinds it is different types ofAttaching plug.It can choose required attaching plug at opposite lower housing section rotatable top shell part.The upper housing portionDividing has an outwardly projecting driving sliding block.The driving sliding block can be made to engage each attaching plug element.For this purpose, being revolvedGo to the position above the attaching plug, and when being rotated to position below the attaching plug, the power supply is insertedHead will be removed from the shell.
The change-over plug for travel has many purposes.But the relatively described lower housing section machinery rotatable top shell partAccurate shell production process is needed, to allow the rotary motion of lower resistance and guarantee that the driving sliding block is reliably made to existEach shell position engages attaching plug element.In addition, round itself is also a kind of limitation.In many cases, for example, it is blockyChange-over plug for travel perhaps can be considered as more easily transporting.It, cannot be from a certain also, on round change-over plug for travelAngle sees all selectable attaching plug elements.
10 2,011 014 920 B4 of German patent DE discloses another change-over plug for travel, is referred to as " general turnInsert head ".In this change-over plug for travel, multiple groups pin is provided in external shell.Every group of pin connects a control element,It can be mobile from outside by every group of pin described in those control elements.Guide the control member on the housing by sliding slotPart.Additionally the control element is guided using the baffle being arranged in external shell.The baffle has guide rail, andThe control element can pass through groove thereon.The guide rail provides upper end position and lower end position.To the baffle elasticityGround prestress, so that control element can be firmly held in the upper end position or lower end position.The control element and rightThe pin group answered can be released from the end position, and be moved up or down, this is because except the control is startedThe selector for being also disposed at outside is also started outside element.The baffle confrontation spring force can be moved by pressing the selector.WithThis method, can be from thereon or lower end position is shifted out by using control element pin.
In this scheme, external control element had both been used to for pin group being moved to from the first end position (standby position)The second end position (uses position), is also used to lock those pin groups in these positions.Its existing drawback is to makeOperating status necessarily also is in selector during the mobile pin group of control element.Comfortable singlehanded behaviour is not can be carried out thusMake.In addition, the control unit cannot move freely in the sliding slot, this is because flexibly pre-add is answered in moving processThe baffle of power continuously squeezes always the control element.And when operating the selector, faulty operation can also make two groups to insertFoot is moved to using on position, or at least towards using position mobile.
Summary of the invention
The object of the present invention is to provide one kind to avoid insufficient improved travelling converter in the prior art.The travelling turnsParallel operation should be able to save cost and reliably be manufactured, and be easy to transport and operate, and electricity aspect is very safe.
Change-over plug for travel of the invention has shell, which can have various shape.For example, in general, bulk is to fortuneIt is very practical for defeated.But the function mode of change-over plug for travel of the invention be designed to can largely freelySelect the shape of shell.It is advantageous when shell has at least one flat face, but function mode of the invention is also suitable forCurved surface of shell.The shell may include one or more pieces.It has been proved that it is useful, tool that the shell, which includes two parts,It is lower housing section and upper case portion for body.It is removably connected to each other, such as using mechanical means, is madeIt is useful with screw connection.
The shell should have at least one socket.The socket is effectively arranged on the housing upper face.The socket canWith different shapes, this depends on the type of the attaching plug to be assigned thereon (hereinafter referred " plug ").For example, such asSchuko plug is assigned on the fruit socket, then just there is basically cylindrical depressed section on the socket, additionally haveFor assigning the female connector (female connector) of the Schuko plug.For other kinds of plug, do not need to haveRecess or groove.It is useful, settable multiple female connectors (female contact) on the face that flat upper casing dignity, which is arranged,.In general, at least two female connectors should be arranged, the female connector pair for assigning standard plug is formed.In order to assign it is multiple notWith the plug of standard, multiple female connectors are set to being useful.If plug also has earth conductor, and socket meaning will mentionFor the chance of ground connection, in general, setting third female connector, or the plug to be assigned of foundation provide third connector, and necessary's.
The change-over plug for travel should also have the plug of at least one the first standard and the second plug of the second standard.(these plugs are also sometimes referred to as " plug-in type pin group (plug-in pin sets) ").The plug of first standard can be withIt is, such as EU European plugs that the plug of the second standard can be the American plug of US.These plugs can have there are two pin, that is, itIt is earth-free；Alternatively, they can have, there are three pins, to provide grounding pin.Therefore, change-over plug for travel of the invention is suitable forIt is used in more than one country.
Usefully, in general, select one using being also necessary to first plug and second plug.InstituteStating change-over plug for travel may also include three or more plugs.It has been proved that band there are three or four plugs travelling conversionPlug is highly useful.At least one of which plug (but usually all plugs) can by from standby position (in this position,Plug is placed in shell substantially) it is moved to using on position.Position is being used, plug is placed in completely or at least partially usablelyOutside shell.Regularly, when plug is back to standby position, plug can be moved back in shell completely.Plug can be moved back in shellIt is useful for not interfering other plugs as far as it enough.
First plug is connect with a driving sliding block, which is used to move first plug from standby positionTo using position.Second plug is also connect with a driving sliding block, is used to the second plug moving to use from standby positionPosition.Therefore, the change-over plug for travel at least has the first driving sliding block and the second driving sliding block.Those driving sliding blocks can haveIt is designed to button-like mode to effect, it is mobile with a finger to make it easier to.It, can be on shell in order to accommodate the driving sliding blockSliding slot is set.Those sliding slots can also be connected with each other to form the guide rail for the driving sliding block.It in general, is each driveA sliding slot is all arranged in movable slider, and these sliding slots are arranged parallel to each other, and is useful.
Slide selector can be set on the change-over plug for travel, which can at least be moved to first positionAnd the second position.In its first position, which discharges first plug；Alternatively, in its second position, the slidingSelector discharges the second plug, thus, it is possible to alternatively move to first plug or the second plug using on position.
By this method, the slide selector provides the additional advantage of practicability for the change-over plug for travel.By tripIt is not repeatedly uncommon that row changeover plug, which is brought to same destination country,.In a destination country by required plug at itIt by it from using position to be moved back to standby position is also very common when being not needed.Therefore, when can be selected in the slidingIt is highly advantageous for selecting when adjusting corresponding type of plug on device.It is very simple that the slide selector, which is marked, canUnderstand destination country easily to distinguish and can be adjusted on it.Once the slide selector moves on appropriate location, then onlyThere is corresponding plug that can be moved to using on position.Usually, it means that be only possible to a mobile driving sliding block.
Due to change-over plug for travel should always be configured to it is compacter, the driving sliding block is usually within close proximity each other.So such as finger is not precisely placed to inadvertently move neighbouring driving sliding block on driving sliding block simultaneouslyThe case where will be easy to occur.However, thus (usual) also only allows to drive since the present invention only allows to drive a plugOne driving sliding block, so the driving sliding block accidentally touched will not move (or it will not at least move associated plug).This can make the operation of the change-over plug for travel become more fault-tolerant.
However, setting, which can only discharge a plug and the slide selector of a driving sliding block, also has important safetyAdvantage.If removing more than one plug simultaneously, electric current will be not used to the connector flowing of this standard by those.Change-over plug for travel can be damaged in this way, in the worst case, can also damage equipment connected to it, or even cause to hurt to userEvil.
The plug can be moved to using on position using the driving sliding block.Safe handling for change-over plug for travelFor, even if remaining at when the plug counter pressure is inserted into power outlet using being critically important on position.At thisIn the system of invention, settable stop or locking member with ensure the plug be maintained at using on position and by they prevent inThis.The locking member can prevent at least one plug of the change-over plug for travel；The locking member can also effectively will be moreA or all plug is prevented using on position.
Usefully, the locking member is designed as the component independently of the slide selector.Reality as individual componentsApplying mode, it has the advantage in production.The slide selector is the component that need not be transmitted or be subjected to more energetically.However, due toThe property of its own, the locking member must apply enough power being maintained at the plug of every kind of standard using on position.
It is useful when the locking member is also independently of the component of the driving sliding block based on similar reason.In the case, when there is the locking member at least one to be not belonging to a part of the slide selector or driving sliding blockWhen component, the locking member should be construed as individual components.In general, whole components when the locking member are designed to bothIndependently of the component of the slide selector, but independently of it is described driving sliding block component when, be useful.
When the locking member (if if being provided with) Connection Release button be it is useful, which is set to shellIt is driven outside body and along release direction.When by a plug by using position to be moved back to standby position, such release button canKeep the locking member intuitive and safely discharges.Such design is compared with those by driving sliding block or slide selector, even slottingCertain movements of head itself seem safer to discharge the design of plug, also more reliable.So that the release button will not be by nothingIt is driven between meaning, it can also be equipped with warning indicator or design warning coloration, such as red.The release button can be the one of shellPart, for example, when a part due to suitably designing the shell can be pressed.In general, a recess is arranged on shellAnd the release button is set in this recess as the part independently of shell, it is useful.Usefully, the release button canIt is positioned opposite with the slide selector and/or the driving sliding block.
Against the release direction, to the locking member, flexibly prestress (typically: spring biasing) is useful's.To the locking member, flexibly prestress can make the plug be reliably caught in locking shape using position once entranceState.When the spring is accurately acted against the release direction, it is also advantageous in mechanical aspects.
The effective embodiment of the one of the locking member is that the locking member has at least one locking supporting leg, and the lockSupporting leg is determined with sliding surface and locking projections.It can be slided on the sliding surface with one by the element that mobile plug is connected.LaterThe element may be stuck at the locking projections, to lock the plug being connected with the element.
Such change-over plug for travel is useful: its at least one plug have slide protrusion or mechanically with it is suchSlide protrusion securely connects, and the slide protrusion runs and can present in the locking projections on the sliding surfaceLock state.
Such change-over plug for travel is also useful: its locking mechanism have multiple locking supporting legs, such as 2,3 or4 locking supporting legs.The quantity of the locking supporting leg is identical with the quantity of plug.When the quantity of the locking supporting leg is less than slottingIt is also useful and enough when the quantity of head.
Especially later in the case where, when each of at least two plug is connected with slide protrusion, and the twoSlide protrusion is all useful when running on the same locking supporting leg of the locking member.Since the two slide protrusions existIt is run on same locking supporting leg, therefore, this means that the two slide protrusions in same sliding surface and same locking projectionsIt is run on (lock state can be presented in two slide protrusions on it).Because two plugs on the change-over plug for travel are notIt can be simultaneously displaced and use on position, so this locking shape can be alternatively presented in the slide protrusion in the locking projectionsState.However, if two slide protrusions, such as two slide protrusions of adjacent header, a shared size suitably lock branchIf leg, then the quantity of locking supporting leg can be reduced, thus the change-over plug for travel can be configured to more succinct.
In the context of the present invention, the slide selector can be set to any suitable form.In general, mechanicalOn should only allow a plug to move and inhibit other plugs move.Usefully, the slide selector may act on the driveMovable slider, each driving sliding block are connected with certain plug.And it is connected when the slide selector is acted on the plugIt is when another element and useful.
The slide selector can have slide selector ontology, which can be placed in the travelling conversionInside plug casing.Furthermore be arranged on shell a groove be it is useful, which can make to grasp the slide selectorMake.For example, an activation button (hereinafter also referred to " slide selector button ") can be used by the groove.The slide selectorOntology can also be placed in outside the shell, act on the driving sliding block outside shell thus, or thus by a through-holeThe driving sliding block is acted in inside.
At least one plug or whole plugs can connect a joint element, which cooperates with the slide selectorTo prevent the plug from being moved to using on position.Usefully, which may be designed as a convex block or substantially one convexIt rises.The movement of the joint element can be prevented by a catch elements of the slide selector, such as be hindered by strip, card convex etc.Only.Those card convexs are effectively continuously arranged, so that those card convexs form the cassette tape (blocking strip) of pectination.According to selectionThe position of element also should can not prevent the movement of joint element, but it is allowed to pass through.For this purpose, advantageously, the locking memberPart can have multiple grooves for passing through the joint element.For example, can be arranged in the slide selector a series ofProtrusion and recess.
It is useful when having sliding slot on the shell of the change-over plug for travel.The driving sliding block can be in these sliding slotsInterior operation.It may also set up a sliding slot in the slide selector.These sliding slots can be such that sliding block is moved while being directed to.Therefore, a kind of advantageous and cost-effective mechanical conceptual is embodied.Since multiple drives being usually arranged on change-over plug for travelMovable slider, so being particularly advantageous when multiple driving sliding blocks can be guided in the sliding slot in a simple manner.In the background of the invention, the driving sliding block must only cause the movement of the plug, movement usually up and down.The plug need not be locked in using on position, need not also ensuring primary a plug only to may be selected by the driving sliding block.CauseIt is only allowed for the driving sliding block in background of the present invention and executes a kind of function, it is possible to easily and reliably to it in sliding slotIt is guided.For example, guiding in sliding slot to it will become less if loading onto spring to the driving sliding blockHandy, this is often as such sliding block and tends to tilt, and runs meeting " as hook ", just has bigger resistance certainlyPower.
It as already described, is to have when cannot change the position of selection element again when plug one is moved to using on positionBenefit.Thus, it is possible to provide a latch component.The latch component is effectively arranged in the slide selector or coupled.Latch component and slide selector can be integral component or at least one connected whole parts.
With the first function element for cooperating with first plug and for cooperating with second plugThe latch component of two function element is useful.In order to make the latch component be simple to manufacture and it is cost-effective, when first functionElement and the second function element are useful when constructing in the same manner.First function element and the second function element can be allIt is obtained from identical component or similar components.
It is special when the latch component has the finger that can be bonded in the receiver member being bonded with shellIt is not useful.The function element can effectively be designed to finger form.The latch component also can have protrusion or convexBlock, rather than finger.The receiver member may be configured to, such as raised or recessed on latch guide member (latch guide)It falls into.The receiver member can be also configured to groove or hole on the component being connected on shell or with shell.
It is useful when the latch component includes spring element.The latch component even can be all by a springElement is formed, such as is formed by plane spring (flat spring) (or flat spring).It can be used such spring to the latchThe flexibly prestress of the finger of element.The direction of spring force is directed to the receiver member on shell.As long as allPlug is all on standby position, then the spring will be prevented from advancing by leaps and bounds in corresponding receiver member.
As soon as a finger of the latch component is at once towards the spring when plug is moved to using on positionWhen elastic force is pressed into a groove, it is advantageous.
When the spring element of the latch component is in the storage member for accommodating the finger and being connected with shellIt is useful when flexibly preloading its finger on the direction of part.Later, as long as plug is on standby position, so that it may makeThe finger is effectively prevented with the element connected with the stabilizing plugs to be bonded in corresponding receiver member.For example, working asIt is useful when the component of the driving sliding block undertakes this work.For example, the driving sliding block can connect the sliding surface, whenWhen the driving sliding block is moved to using on position, the sliding surface slides in the finger, but works as the driving sliding blockIn when using on position, the sliding surface then discharges the finger so that the finger for distributing to driving sliding block falls into distributionTo in the groove of the finger.

Fig. 4 shows the bottom of same change-over plug for travel, and other details can be more accurately seen from the figure, becauseThis, will be described in detail these details in conjunction with this figure.The bottom view shows driving sliding block 22-28 and sliding select button 20Without much stretching out lateral surface of shell.Succinct and convenient to use arrangement is allowed in engineering design of the invention, in this arrangementIn, driving sliding block is within close proximity to each other.It slides select button 20 and is slightly higher than the driving sliding block, therefore stretch out ground and be slightly distal toThey.
The haptic element of European plugs 34 is guided in header body 32, the haptic element of other standards plug is by from shell bottomPortion's export, and it is not provided with additional header body.Every two haptic element (i.e. a pair of of haptic element) is for being inserted into country variant standardIn power outlet.Haptic element is used for Britain, the English haptic element of hereinafter also referred to as UK to 36A；Haptic element is used for Australia to 36B, underAUS Australia formula haptic element pair is also referred to as in text；Haptic element is used for the U.S., the American haptic element pair of hereinafter also referred to as US to 36C.It is additionally provided with and connectsGround terminal 36D, the ground terminal are used for Britain, therefore the English ground terminal of also referred to as UK, can be grounded using this connector.SoAnd in general, such connector can also be provided when no ground terminal is available.It that case, this connector is for being inserted into UKThe first pin (opening pin) of English power outlet, the first pin make it possible to be inserted into other two connector.
As can be seen that release button 40 is oppositely arranged with the driving sliding block and the sliding select button just.At thisIt is quite useful in a housing side by the sliding select button and all setting of driving sliding block under the background of invention's.It for safety and intuitively operates, in general, release button 40 is arranged to corresponding thereto to be also useful.
Fig. 5 shows the component of the selected collaborative work of the change-over plug for travel in exemplary embodiment in perspective view,It illustrates lower housing sections 14.The header body 32 for belonging to European plugs is placed in below shell.The position of corresponding plug ontology 32It sets, the first driving sliding block 22 is illustrated on lower position.On the front face, the shell has sliding slot 42.It can from figureTo there are four the sliding slots 42 being disposed adjacent, wherein each sliding slot can receive a driving sliding block.However, rising for ease of understandingSee, depicts only the first driving sliding block 22.It can be seen that slide selector ontology 44 is located at the top of the sliding slot, for accommodatingThe recess 46 and slide selector ontology 44 of the release button are opposite.
In addition, the slide selector ontology is illustrated in position when it is used in complete change-over plug for travel, but do not haveHave and shows the component for maintaining it in this position.Description that this simplifies is also for being easy to understand.By slide selector ontology44 are set to above the driving sliding block, i.e., relatively with housing bottom (haptic element can be exported by it and moved to using on position),It is useful.
Fig. 6 essentially shows the component shown in Fig. 5 from one side visual angle, depicts lower housing section 14 againAnd slide selector ontology 44.Slide selector ontology 44 is illustrated in its position kept by other component (not shown) againOn.What is be also shown as is the second driving sliding block 24 of neighbouring first driving sliding block 22.First driving sliding block 22 is illustrated in lower portionAnd armed bit it sets, i.e., with the use position corresponding of plug, the second driving sliding block 24 is illustrated on upper position, i.e.,Set corresponding position.
In this view, it can be seen that the back side (its inside towards change-over plug for travel) of slide selector ontology 44 hasThere is card convex 48.It can further be seen that the first driving sliding block is connected with guid arm 50.The guid arm 50 can be additionally by unshownedComponent support, and ensure to drive the position of sliding block 22 and movement not only to be limited by sliding slot 42.However, in general, only in instituteIt has been enough for stating the guiding driving sliding block in sliding slot.The upper end of guid arm 50, which has, combines convex block 52.
So as to engage engagement protrusion 52 with card convex 48, so that the downward movement of the second driving sliding block 24 is suppressed.
In another side view, Fig. 7 shows the cooperation relation of known elements in Fig. 5 and Fig. 6.It, again can be in Fig. 7It is seen in the lower housing section 14 and slide selector ontology 44 of its appropriate location in complete change-over plug for travel.SlidingThe back side of selector ontology 44 is engaged with the guid arm 50 of the second driving sliding block.At its back side, the slide selector sheetBody has multiple card convexs, card convex 48A, 48B, 48C, 48D and 48E.Groove (groove 54A, 54B, 54C are equipped between each card convexAnd 54D) form channel.Although in position shown in the figure, card convex 48C is engaged with the engagement protrusion of guid arm 50,When the slide selector ontology is in another location, the engagement protrusion of guid arm 50 is just no longer engaged with card convex.On the contrary, movingHolding slide selector ontology 44 can be such that the card convex 48 of the guid arm is placed in above a groove.Thus position, can be towards using positionIt sets and moves down the guid arm and entirely drive sliding block in turn.
Fig. 8 is the side view similar with Fig. 6, but in this figure, depicts an additional component.Under being shown againHousing parts 14, second drive sliding block 24 and slide selector ontology 44.Front has illustrated, and drives sliding block 24 (also like otherDrive sliding block the same) there is guid arm 50.In its end, guid arm 50 has engagement protrusion 52, can be caused and card convex 48Engagement.
Other than component already shown in Fig. 6 and Fig. 7, latch component 56 has also been shown in this view.LatchElement 56 substantially with the shape of flat spring, is bonded the inside (side towards the guid arm of slide selector ontology 44Face).It holds on it, latch component 56 has the finger 58 for stretching out 44 top of sliding selection ontology.The latch component also hasPressure-bearing surface 60 also includes a height (elevation).
The function mode of latch component 56 is as follows.When driving sliding block 24 to be located at the upper position shown, engagement protrusion 52Pressure is applied to pressure-bearing surface 60.When slide selector ontology 44 is located at position appropriate, one moves down the driving sliding block,Engagement protrusion 52 (alternatively, when necessary, another component of guid arm 50) just no longer squeezes pressure-bearing surface 60.Flexibly to finger 58Prestress, so that it is mobile (left side i.e. into Fig. 8 is mobile) towards the center of change-over plug for travel due to spring force.
Once there is no pressure to be applied on pressure-bearing surface 60, which will generate effect, and finger 58 will be moved toOn latch position.In this latch position, the engageable element for fixedlying positioning connection with shell of the finger, which usually may be usedIt is described as finger receiver member.Slide selector ontology 44 can be caused to be also held at the position fixed relative to shell in this wayIt sets.
Fig. 9 is the perspective view of slide selector ontology 44 and latch component 56 (or, being more accurately its finger 58).Latch component 56 can be fabricated by for example curved flat spring.The upper end of slide selector ontology 44 has recess.Latch memberThe finger 58 of part 56 can be inserted by four recesses shown.Firstly, which ensure that latch component 56 and slide selectorOntology 44 is also connected in upper area well each other；Secondly, these recesses make four finger 58A of latch component 56,Movement is possibly realized after 58B, 58C and 58D come between latch position and selection position (or standby position).
Figure 10 is the perspective view of the other direction of slide selector ontology 44 and latch component 56, again can be with from the figureIt is one can easily see finger 58 and its function mode.Latch component 56 should firmly mechanically connect slide selector ontology 44.For this purpose, slide selector ontology 44, which can have, can make that company is easily inserted or engaged between slide selector ontology 44 and latch component 56The groove connect.The contents of the section can be seen from the lower part of slide selector ontology 44.
Figure 11 depicts the cooperation relation between latch component 56 and upper case portion 12 in bottom view.The view directionIt is the bottom that upper case portion 12 is directed toward from lower housing section 14, it is possible to see female connector 18.Before latch component 56 is close toShell wall；In functional change-over plug for travel, also kept by slide selector ontology 44, however, for visual simplification,Slide selector ontology 44 is not shown herein.
On the upside of finger 58A, 58B, 58C and 58D fitting shell of latch component 56.All fingers are showd that in awaiting ordersOn position.As soon as moving into the associated driving sliding block of finger and corresponding plug and using position, which moves into latch positionIt sets.In order to which the finger to be locked on the latch position, locking guide groove 62 is provided on the downside of shell.The locking guide grooveWith groove.In the embodiment being shown here, the groove is separated with adjacent grooves by rod.Locking guide groove 62 shares fourA groove: groove 64A, groove 64B, groove 64C and groove 64D.
Other various forms of locking guide grooves are also possible to useful；In general, the locking guide groove should have phaseTo the finger receiving element of shell firm position.As soon as finger 58 enters groove 64 associated with it, latch component 56 is inThe state of an existing opposite shell firm position.The latch component just can not be moved with slide selector ontology 44 again as a result,It is dynamic；This uplink and downlink movement on view direction can be all blocked.
Figure 12 is the perspective view of other two component to cooperate of the change-over plug for travel.Two components also all showFor under its " nature " position, that is, it is presented on the position in complete change-over plug for travel.Showing is lower housing section 14And locking member 66.In a known manner, there are four sliding slots 42 parallel to each other for the lower housing section tool.Locking member 66With known release button 40.Locking member 66 also has frame 68.On frame 68 equipped with can make locking member 66 with it is describedThe fixation clamp (it is not described in detail) that the other component of change-over plug for travel is connected.Locking member 66 is locked there are three also havingDetermine supporting leg: the first locking supporting leg 70A, the second locking supporting leg 70B and third locking supporting leg 70C.
Figure 13 illustrates how the locking supporting leg operates.In the figure, locking member 66 not with lower housing section14 show together, and show together with the header body 32 for European plugs.Locking member 66 also with other header bodies andHaptic element cooperates, but is only retouched herein with function of the example of European plugs and corresponding plug ontology 32 to locking supporting legIt states.The header body is securely connect with the first driving sliding block 22, and the first driving sliding block 22 has guid arm 50.Header body 32 is alsoConnect slide protrusion 72.The slide protrusion can slide along the first locking supporting leg 70A and in the lower end of the first locking supporting leg 70ALock state is presented.
Figure 14 shows the component in Figure 13, but is shown in a manner of side view, can be more preferable from this viewSee accurate function mode.In this view, it can be seen that the first locking supporting leg 70A (the same also like other locking supporting legs)With sliding surface 74 and locking projections 76.The slide protrusion 72 of header body 32 can slide on sliding surface 74.In order to startThe sliding, locking member 66 can transverse shifting, can move and (scheme in the release direction that limits of direction by release button 40In direction from right to left).To the flexibly prestress of locking member 66, so that slide protrusion 72 squeezes sliding surface 74.When slottingWhen head ontology 32 reaches it using on position, slide protrusion 72 reaches locking projections 76.Due to flexibly pre- to locking member 66Add stress (so as in this figure, being therefore pressed towards right), thus slide protrusion 72 can move on to the lower section of locking projections 76 simultaneouslyThus it is stopped.This prevention is mechanically very favorable, this is because along the principal spread direction of supporting leg 70A is locked to thisLocking supporting leg is loaded, and thus locking supporting leg 70A substantially need to only absorb compressing force.However, by pressing release button 40,This stop can be certainly discharged, also, the header body can be moved back on its standby position along sliding surface 74.
In a manner of more specifically being described in be broadly described and attached drawing, can production operation as snug as a bug in a rug and hardlyThe travelling converter for thering is operating mistake to occur.However, interestingly, the travelling converter and inexpensive is produced, and even if bigMust be allowed in batch production it is larger it is fault-tolerant in the case where, can also inexpensively and reliably produce the travelling converter.
