Referring to fig. 1, an embodiment of the present disclosure provides awiring device 100. Thewiring connection device 100 includes: theconductor bar assembly 110, theswitching roller 120, the first conductor (not shown), themounting box 140, thefirst harness 151, theplug 152, and thesecond harness 153. Theconductor bar 111, theswitching roller 120, and the first conductor site are disposed in themounting case 140.

Theswitching roller 120 is provided with a plurality of sets ofconductor bar assemblies 110 arranged in the circumferential direction, and each set ofconductor bar assembly 110 includes a plurality ofconductor bars 111 arranged in sequence in the axial direction of theswitching roller 120.

Specifically, as shown in fig. 1, thewiring connection device 100 further includes amounting bracket 121. Themounting frame 121 is fixed to the bottom wall of themounting case 140. Theswitching roller 120 is installed in theinstallation case 140 through theinstallation frame 121. The switchingroller 120 and the mountingframe 121 may be rotatably coupled by a rotating shaft (not shown), so that the switchingroller 120 can rotate about its axis by the rotating shaft.

The plurality of sets ofconductor bar assemblies 110 are disposed on the outer circumferential surface of the switchingroller 120 and arranged at intervals in the circumferential direction of the switchingroller 120. As shown in fig. 1, theconductor bar assemblies 110 in the present embodiment are three groups, which are, in order, the first group ofconductor bar assemblies 110, the second group ofconductor bar assemblies 110, and the third group ofconductor bar assemblies 110 along the clockwise direction. It is understood that the number ofconductor bar assemblies 110 may be other numbers such as two, four, etc. Each group of theconductor bar assemblies 110 includes a plurality of conductor bars 111, and the plurality of conductor bars 111 are sequentially arranged in the axial direction of the switchingroller 120 so that each group of theconductor bar assemblies 110 is aligned in a row. Different sets ofstub assemblies 110 may include different numbers ofstubs 111 and may include the same number ofstubs 111. For example, in the three groups ofconductor bar assemblies 110 of the present embodiment, the first group ofconductor bar assemblies 110 includes fourconductor bars 111, the second group ofconductor bar assemblies 110 includes threeconductor bars 111, and the third group ofconductor bar assemblies 110 includes five conductor bars 111.

The first conductor is disposed opposite to the outer circumferential surface of the switchingroller 120. The plurality of first conductors are arranged in order in the axial direction of the switchingroller 120. The switchingroller 120, when rotated about its axis, can selectively engage any one of the plurality of sets ofconductor bar assemblies 110 with a plurality of first conductors. When theconductor bar assemblies 110 are mated with the first conductors, eachconductor bar 111 in the set ofconductor bar assemblies 110 is electrically connected with a corresponding first conductor.

In particular, the first conductor may be a conductor block, a conductive contact, or the like. As shown in fig. 1, in the present embodiment, thewiring connection device 100 further includes a mountingportion 180, and the mountingportion 180 is fixedly connected to an inner wall of the mountingbox 140. A plurality of first conductors may be mounted to the mountingportion 180.

When the switchingroller 120 rotates around its axis, the plurality of first conductors are fixed, so that the switchingroller 120 drives the plurality ofconductor bar assemblies 110 to rotate relative to the first conductors. Since the plurality of first conductors are disposed opposite to the outer circumferential surface of the switchingroller 120, different sets ofconductor bar assemblies 110 can be engaged with the plurality of first conductors by rotating the switchingroller 120 by different angles.

The number of the first conductors is greater than or equal to the number of the conductor bars 111 in each group of theconductor bar assemblies 110, so that when each group of theconductor bar assemblies 110 is matched with a plurality of first conductors, eachconductor bar 111 in the group of theconductor bar assemblies 110 can be respectively contacted with the corresponding first conductor, thereby realizing the electrical connection. For example, the number of first conductors may be five. When the first group ofconductor bar assemblies 110 are engaged with a plurality of first conductors, the fourconductor bars 111 in the first group ofconductor bar assemblies 110 are respectively connected with the corresponding first conductors, so that the fourconductor bars 111 are electrically connected with the four first conductors, and the remaining one of the first conductors is not connected with the conductor bars 111. If the third group ofconductor bar assemblies 110 is matched with a plurality of first conductors, fiveconductor bars 111 in the third group ofconductor bar assemblies 110 correspond to five first conductors one by one.

In the present embodiment, thewiring device 100 is used to connect the secondary terminal box of the capacitance voltage transformer with a testing apparatus 11 (such as a dielectric loss meter) so as to perform a preventive test on the capacitance voltage transformer through thetesting apparatus 11.

Specifically, as shown in fig. 1, one end of thefirst wire harness 151 is located inside theinstallation case 140 and connected to the first conductor, and the other end is connected to theplug 152 and located outside theinstallation case 140. Wherein thefirst wire harness 151 includes a plurality of first wires (not shown). Theplug 152 includes a plurality of pins. When one end of thefirst harness 151 is connected to the first conductor, the first harness is electrically connected to the first conductor through one end of a first conductive wire, and the first conductive wire and the first conductor are in one-to-one correspondence. When the other end of thefirst harness 151 is connected to theplug 152, the other end of the first wire is electrically connected to the contact pin, and the first wire corresponds to the contact pin one to one. Theplug 152 is adapted to be inserted into a receptacle of a secondary terminal box of a capacitive voltage transformer. And, the pins of theplug 152 correspond one-to-one with the secondary terminals of the secondary terminal box of the capacitance voltage transformer.

One end of thesecond harness 153 is used for connecting the conductor bars 111, and the other end of thesecond harness 153 is used for connecting thetest instrument 11. Thesecond harness 153 includes a plurality of second conductive lines. When one end of thesecond wire harness 153 is connected to theconductive bars 111, eachconductive bar 111 is electrically connected to a corresponding second conductive wire. The twoconductor bars 111 of theconductor bar assemblies 110 of different groups may correspond to the same second conductive wire or different second conductive wires. When the other end of the second wire is connected to thetest instrument 11, the other end of the second wire corresponds to the terminals of thetest instrument 11 one to one.

Since the first wires are in one-to-one correspondence with the first conductors and electrically connected, and the conductor bars 111 in theconductor bar assemblies 110 are respectively electrically connected with the corresponding second wires, when any one group ofconductor bar assemblies 110 is matched with a plurality of first conductors, thesecond wire harness 153 can be electrically connected with thefirst wire harness 151, so that the secondary terminal box of the capacitance voltage transformer can be electrically connected with thetest instrument 11.

According to the difference of the test items, aiming at the wiring requirements of different test items, various different wiring modes can be set. In the present embodiment, different wiring patterns can be formed in thewiring device 100 by matching different sets of theconductor bar assemblies 110 with a plurality of first conductors, and therefore, each set of theconductor bar assemblies 110 can correspond to one wiring pattern and one test item, respectively. When a certain test item needs to be performed, the switchingroller 120 can be rotated to drive the plurality of groups ofconductor bar assemblies 110 to rotate, so that theconductor bar assemblies 110 corresponding to the test item are matched with the plurality of first conductors, thewiring device 100 can be switched to the wiring mode corresponding to the test item, the secondary terminal box of the capacitor voltage transformer can be electrically connected with thetesting instrument 11, and the wiring mode is rapid, convenient and accurate to the corresponding wiring mode.

Thewiring device 100 is used for connecting the secondary terminal box of the capacitance voltage transformer with thetest instrument 11, and is used for inserting theplug 152 into the secondary terminal box and electrically connecting thesecond wire harness 153 with the terminal of thetest instrument 11 when performing preventive test items on the capacitance voltage transformer. When a certain test item needs to be performed, the switchingroller 120 can be rotated to drive the plurality of groups ofconductor bar assemblies 110 to rotate, so that theconductor bar assemblies 110 corresponding to the test item are matched with the plurality of first conductors, thewiring device 100 can be switched to the wiring mode corresponding to the test item, the secondary terminal box of the capacitor voltage transformer can be electrically connected with thetesting instrument 11, and the wiring mode is rapid, convenient and accurate to the corresponding wiring mode.

Compare the mode of connection when carrying out the test project in traditional capacitance voltage transformer,use termination 100 of this application to carry out the wiring, need not carry out a lot of and tear open the wiring to be difficult for causing the wiring mistake, and can use manpower sparingly and time. And only oneplug 152 is required to be inserted into the secondary terminal box, and excessive plugs do not need to be arranged.

It is understood that thewiring device 100 can also be used for connection between other electrical equipment and a test instrument, and is not limited to the capacitive voltage transformer and thetest instrument 11 in the present embodiment.

Referring to fig. 1, in an embodiment, thewire connection device 100 further includes adriving mechanism 161 and a deceleration mechanism. Thedriving mechanism 161 is used for driving the speed reducing mechanism to move, and the speed reducing mechanism is used for driving the switchingroller 120 to rotate.

Specifically, in the present embodiment, thedriving mechanism 161 is a motor. The speed reducing mechanism is a worm and gear mechanism. As shown in fig. 1, the speed reduction mechanism includes aworm wheel 162 and aworm 163. The switchingroller 120 is controlled at a low speed by the deceleration of the deceleration mechanism.

Referring to fig. 1, in an embodiment, thewire connecting device 100 further includes acontrol device 164 for controlling thedriving mechanism 161 to drive the switchingroller 120 to rotate.

Specifically, thecontrol device 164 may be a single chip, a microprocessor, a controller, or the like. The rotation speed, start, and stop of the motor, and the like can be controlled by thecontrol device 164, so that the rotation speed, start, and stop of the switchingroller 120 can be controlled.

Referring to fig. 1, in an embodiment, thewiring connection device 100 further includes a mountingportion 180 fixed to the mountingbox 140. The mountingportion 180 is provided opposite to the outer circumferential surface of the switchingroller 120, and the plurality of first conductors are mounted to the mountingportion 180.

Specifically, as shown in fig. 1, in the present embodiment, the mountingportion 180 is fixed to the top wall of the mountingcase 140, so that when the first conductor is mounted to the mountingportion 180, the first conductor can be positioned above the switchingroller 120, and the first conductor can be conveniently disposed opposite to the outer circumferential surface of the switchingroller 120.

Referring to fig. 1 in conjunction with fig. 2, in an embodiment, the mountingportion 180 has an inner surface and an outer surface opposite to the inner surface, and the inner surface is attached to the outer circumferential surface of the switchingroller 120. The inner surface is provided with a plurality of switchinggrooves 101 arranged in order in the axial direction of the switchingroller 120. Each switchinggroove 101 extends in the circumferential direction of the switchingroller 120. The first conductors are installed in the switchinggrooves 101 and correspond one-to-one to the switchinggrooves 101. Theconductor bar 111 is located in the switchinggroove 101 and can rotate along the switchinggroove 101.

Specifically, as shown in fig. 1, in the present embodiment, the mountingportion 180 is a housing that extends in an arc shape and has a circumferential direction extending in the same direction as the circumferential direction of the switchingroller 120. The inner surface of the mantle is fitted to the outer circumferential surface of the switchingroller 120 and is attached to the switchingroller 120.

Referring to fig. 2, the plurality of switchinggrooves 101 are sequentially arranged along the axial direction on the inner surface, so that the first conductors can be respectively installed in the respective corresponding switchinggrooves 101, and the conductor bars 111 are respectively located in the respective corresponding switchinggrooves 101, so that the first conductors can be isolated from each other. When the switchingroller 120 rotates the conductor bars 111, the conductor bars 111 rotate along the respective corresponding switchinggrooves 101.

Because the inner surface of the housing is matched with the outer peripheral surface of the switchingroller 120 and is attached to the switchingroller 120, the switchinggrooves 101 are formed in the inner surface of the housing, and the first conductors and the conductor bars 111 are respectively positioned in the corresponding switchinggrooves 101, the first conductors and the conductor bars 111 can be sealed in the switchinggrooves 101, and the first conductors are isolated from each other, so that when the switchingroller 120 drives theconductor bar assembly 110 to rotate to be in contact with the first conductors, the arc can be prevented from overflowing from the housing, and an explosion-proof effect can be achieved.

Referring to fig. 3, in an embodiment, thewiring connection device 100 further includes elastic clip assemblies corresponding to the first conductors one by one, and the elastic clip assemblies are mounted on the mountingportion 180 and are used for being clipped to the conductor bars 111. Theconductor bar 111 can be electrically connected to the first conductor when it is engaged with the spring clip assembly. The spring clip assembly has aclip cavity 102 for receiving astub 111. The clampingcavity 102 has openings at both ends, and when the switchingroller 120 drives theconductor bar 111 to rotate, theconductor bar 111 can enter theclamping cavity 102 from theopening 103 at one end of theclamping cavity 102 and can leave theclamping cavity 102 from theopening 104 at the other end of theclamping cavity 102.

Referring to fig. 3, the elastic card assembly includes a firstelastic latch 191 and a secondelastic latch 192. The first and secondelastic snaps 191 and 192 may be respectively mounted to the mountingpart 180. The firstelastic latch 191 and the secondelastic latch 192 are oppositely arranged so as to enclose theclamping cavity 102.

When theconductor bar 111 rotates along with the switchingroller 120, theconductor bar 111 can enter theclamping cavity 102 from theopening 103 at one end of theclamping cavity 102, and at the moment, the firstelastic clamping piece 191 and the secondelastic clamping piece 192 can clamp theconductor bar 111, so that theconductor bar 111 is clamped with the elastic clamping piece, the position of theconductor bar 111 can be stable, and the conductor bar can be well connected with a first conductor. The switchingroller 120, which carries theconductor bar 111 to rotate, can overcome the clamping force of the firstelastic latch 191 and the secondelastic latch 192, so that theconductor bar 111 can leave theclamping cavity 102 from the other end opening 104 of theclamping cavity 102.

The first conductor may be disposed on the inner wall of theclamping cavity 102, i.e., the inner surfaces of the first and secondresilient latches 191 and 192, so that when theconductor bar 111 is clamped by the first and secondresilient latches 191 and 192, a good electrical connection can be maintained with the first conductor.

The firstelastic jaw 191 and the secondelastic jaw 192 may be made of elastic material to facilitate the clamping force of theconductor bar 111 and to easily overcome the clamping force of the firstelastic jaw 191 and the secondelastic jaw 192 when the switchingroller 120 continues to rotate theconductor bar 111. The first and secondresilient latches 191 and 192 may be made of, for example, a rubber material.

Of course, in other embodiments, thefirst spring catch 191 and thesecond spring catch 192 may be made of metal, in which case the first conductor includes thefirst spring catch 191 and thesecond spring catch 192, respectively. When theconductor bar 111 is clamped by the first and secondresilient latches 191 and 192, good electrical connection can be maintained with the first and secondresilient latches 191 and 192, that is, theconductor bar 111 is kept in good electrical connection with the first conductor.

Referring to fig. 1 and 4, in an embodiment, thewiring connecting device 100 further includes asensing contact 172 and a plurality ofsensing contacts 171. Thesensing contacts 171 are disposed on the switchingroller 120 and sequentially arranged along the circumferential direction of the switchingroller 120, and thesensing contacts 171 correspond to theconductor bar assemblies 110 one to one. When the switchingroller 120 rotates thesensing contact 171, any one of thesensing contacts 171 can be engaged with thesensing feeler 172. When the switchingroller 120 stops rotating, the selectedsensing contact 171 can trigger the switchingroller 120 to stop rotating when thesensing contact 172 is matched with thesensing contact 172, and when the switchingroller 120 stops rotating, theconductor bar assembly 110 corresponding to the selectedsensing contact 171 can be matched with the plurality of first conductors.

Specifically, thesensing contact 172 may be installed in theinstallation case 140 through the fixingbar 173, and thesensing contact 172 is disposed opposite to the outer circumferential surface of the switchingroller 120. As shown in fig. 1, in the present embodiment, the number of thesensing contacts 171 is three, and the first sensing contact, the second sensing contact and the third sensing contact are sequentially arranged in a clockwise direction in fig. 1. The threesensing contacts 171 correspond to the three sets ofconductor bar assemblies 110 one-to-one, the first sensing contact corresponding to the first set of conductor bars 111, the second sensing contact corresponding to the second set of conductor bars 111, and the third sensing contact corresponding to the third set of conductor bars 111. The threeinduction contacts 171 are disposed on the outer circumferential surface of the switchingroller 120 and are sequentially arranged along the circumferential direction of the switchingroller 120, so that theinduction contacts 171 can be driven to rotate when the switchingroller 120 rotates. By rotating the switchingroller 120 by different angles,different sensing contacts 171 can be engaged with thesensing feelers 172.

Specifically, as shown in fig. 1,different function switches 165 may be configured for thecontrol device 164, different wiring patterns may be set in thecontrol device 164, and the function switches 165 may correspond to the wiring patterns one to one. Since the connection pattern corresponds to theconductor bar elements 110 one by one, and theconductor bar elements 110 correspond to thesensing contacts 171 one by one, when acertain function switch 165 is pressed, the connection pattern corresponding to thefunction switch 165 can be selected in thecontrol device 164. When the connection mode corresponding to thefunction switch 165 is selected, theconductor bar assembly 110 corresponding to the connection mode and thesensing contact 171 corresponding to theconductor bar assembly 110 are selected.

For example, a certain wiring pattern of thewiring device 100 corresponds to the third group ofconductor bar assemblies 110 in which the third group ofconductor bar assemblies 110 mate with the plurality of first conductors. If theconnection device 100 needs to be set to the connection mode, thefunction switch 165 corresponding to the connection mode can be pressed. Since the wire connection mode corresponds to the thirdconductor bar assembly 110, and the thirdconductor bar assembly 110 corresponds to the third sensing contact, thecontrol device 164 controls thedriving mechanism 161 to drive the switchingroller 120 to rotate, so that the switchingroller 120 rotates until the third sensing contact is matched with thesensing contact 172. The third trigger signal can be generated when the third sensing contact is mated with thesensing contact 172. When thecontrol device 164 receives the third trigger signal, thecontrol device 161 stops driving the switchingroller 120, and when the switchingroller 120 stops rotating, the third groupconductor bar assembly 110 can cooperate with the plurality of first conductors, so as to accurately switch thewiring device 100 to the wiring mode corresponding to the third groupconductor bar assembly 110.

Similarly, if thewiring device 100 needs to be switched to another wiring mode, thefunction switch 165 corresponding to the other wiring mode is pressed, so that thecontrol device 164 can control the switchingroller 120 to drive thesensing contact 171 corresponding to the other wiring mode to be matched with thesensing contact 172. When thesensing contact 171 corresponding to the other wire connection mode is engaged with thesensing contact 172, thecontrol device 164 can be triggered to control the switchingroller 120 to stop moving. When the switchingroller 120 stops rotating, theconductor bar assembly 110 corresponding to the other connection mode is engaged with the first conductor, and thewiring device 100 can be accurately switched to the other connection mode.

It is understood that in other embodiments, the plurality of function switches 165 may not be provided, and different wiring modes may be selected in other manners, such as by way of display screen input.

In one embodiment, eachsensing contact 171 is connected to an output of thecontrol device 164, and thesensing contact 172 is connected to an input of thecontrol device 164. Different voltages can be output todifferent sensing contacts 171 through the cooperation of the additionally configured circuit and thecontrol device 164, and thesensing contacts 171 correspond to the voltages one by one, so that whendifferent sensing contacts 171 are matched with thesensing contacts 172, different voltage signals can be received by thecontrol device 164.

When afunction switch 165 is pressed, and a connection mode corresponding to thefunction switch 165 is selected, theconductor bar assembly 110 corresponding to the connection mode and thesensing contact 171 corresponding to theconductor bar assembly 110 are selected, that is, a voltage signal corresponding to thesensing contact 171 is selected.

When thecontrol device 164 controls the switchingroller 120 to rotate until thesensing contact 171 is matched with thesensing contact 172, thecontrol device 164 can receive a voltage signal corresponding to thesensing contact 171. When the voltage signal received by thecontrol device 164 matches the selected voltage signal, thecontrol device 164 can determine that the selectedsensing contact 171 is engaged with thesensing contact 172, so that thecontrol device 164 can timely control the switchingroller 120 to stop moving, so that theconductor bar assembly 110 corresponding to thesensing contact 171 can be engaged with the first conductor, and thewiring device 100 can be accurately switched to the wiring mode corresponding to theconductor bar assembly 110.

Referring to fig. 1 and 4, in an embodiment, thewiring connection device 100 further includes aspring 174. One end of thespring 174 is connected to the fixingrod 173, and the other end is connected to thesensing contact 172. When thesensing contact 171 is engaged with thesensing contact 172, the restoring force of thespring 174 is directed toward thesensing contact 171.

Specifically, when thesensing contact 171 is engaged with thesensing contact 172, the restoring force of thespring 174 is directed to thesensing contact 171, so that the restoring force of thespring 174 can make thesensing contact 171 abut against thesensing contact 172, and further make thesensing contact 171 and thesensing contact 172 maintain good electrical connection, which is beneficial to accurately triggering the switchingroller 120 to stop moving.

Each of the conductor bars 111 is electrically connected to one end of a respective one of the second conductive lines. The other end of the second conductive line is electrically connected to thetest instrument 11, and the second conductive line corresponds to the terminals of thetest instrument 11 one by one.

Thetesting device 10 is used for inserting theplug 152 into the secondary terminal box when performing preventive test items on the capacitance-voltage transformer. When a certain test item needs to be performed, the switchingroller 120 can be rotated to drive the plurality of groups ofconductor bar assemblies 110 to rotate, so that theconductor bar assemblies 110 corresponding to the test item are matched with the plurality of first conductors, thewiring device 100 can be switched to the wiring mode corresponding to the test item, the secondary terminal box of the capacitor voltage transformer can be electrically connected with thetesting instrument 11, and the wiring mode is rapid, convenient and accurate to the corresponding wiring mode. Compare the mode of connection when carrying out the test project in traditional capacitance voltage transformer, usetesting arrangement 10 of this application, need not carry out a lot of and tear open the wiring to be difficult for causing the wiring mistake, and can use manpower sparingly and time. And only oneplug 152 is required to be inserted into the secondary terminal box, and excessive plugs do not need to be arranged.
