Description

TECHNICAL FIELD

[0001] The present application relates to the field of transformer wiring, in particular to a wiring fixing device for a transformer comprehensive power distribution cabinet connector. BACKGROUND

[0002] The transformer comprehensive power distribution cabinet is a device used in the power distribution system, which is usually used for the comprehensive protection, control and power distribution functions of the transformer. In addition to the transformer, the transformer comprehensive power distribution cabinet usually also installs circuit breakers, contactors and controllers and other connector devices. The transformer comprehensive power distribution cabinet connector plays an important role in connection, transmission of electric power, safety protection, wiring and maintenance, and is an essential part of the electrical system.

[0003] Since multiple connector devices are usually required to be installed in the transformer comprehensive power distribution cabinet, multiple wires need to be connected in the transformer comprehensive power distribution cabinet. At the same time, thicker wires are often used to ensure that they can carry larger currents and prevent overheating and circuit breaking caused by overloading of the wires. Therefore, when wiring the transformer comprehensive power distribution cabinet connector, the existing method is to first use a wire clamp to fix multiple wires, and then manually remove the wires from the wire clamp one by one and connect them to the connector device. However, due to the large number of wires in the transformer comprehensive power distribution cabinet, they are easily entangled together, which makes the wiring in the power distribution cabinet messy and inconvenient for later maintenance.

[0004] In view of the above problems, a power distribution cabinet wiring support is disclosed in Chinese Patent No. CN220172595U. The patent allows the wires to pass through the branch port and the card block to be lowered under the action of the return spring to block the wiring, so that the branch port of the branch support can place each wire separately, effectively preventing the wires from being entangled together, facilitating the maintenance personnel to maintain and maintain the power distribution cabinet later, and adjusting the height of the branch support using the height adjusting assembly to make the branch support better adapt to the height of the wiring.

[0005] The above technical solution still has the following problems when wiring the transformer comprehensive power distribution cabinet connector: 1. Due to the space limitation inside the transformer comprehensive power distribution cabinet, the end of the wire needs to be connected to the connector device from different angles. However, the existing wire clamp cannot adjust the angle of the wire end, and the wire end needs to be bent manually, which reduces the wiring efficiency of the transformer comprehensive power distribution cabinet connector; 2. When connecting the wire to the connector device, the wire may be twisted, which can cause the insulation layer of the twisted part of the wire to be easily damaged, reducing the service life of the wire; 3. When the transformer comprehensive power distribution cabinet connector uses thicker wires for connection, the wires are prone to sag due to their own weight, which can cause the connection between the wires and the connector device to be loose, resulting in unreliable electrical connection.

The present invention can also support the wires to prevent the wires from sagging due to their own weight, thereby preventing the connection between the wires and the connector from loosening, so that the wires and the connector can be firmly connected.

[0036] Specifically, first place the U-shaped plate 1 at the position corresponding to the connector in the transformer integrated distribution cabinet, and control the two clamping mechanisms 11 to press against the inner wall of the transformer integrated distribution cabinet to fix the U-shaped plate 1 in the distribution cabinet, and at the same time align the lateral ends of the U-shaped plate 1 and the connector left and right centers.

Then, the adjustment unit 2 is controlled to adjust the distance between adjacent clamping units 3 at equal intervals, and at the same time, the angle of the clamping unit 3 is adjusted to adjust the access angle of the wire end. Finally, the clamping unit 3 is controlled to insert the wire end into the connector, and the wire and the connector are manually connected.

[0037] See Figure 2 and Figure 3 The U-shaped plate 1 has two symmetrically arranged square grooves in the transverse section. The tightening mechanism 11 includes an L-shaped tightening plate 111 slidably installed in the square groove. A fixed block 112 is fixedly installed at one end of the rear ends of the two tightening plates 111 away from each other. Two symmetrically arranged square blocks 13 are fixedly installed at the rear end of the U-shaped plate 1. Both square blocks 13 are installed with tightening screws 113 in the direction of threaded engagement, and the tightening screws 113 and their corresponding fixed blocks 112 are rotatably connected.

[0038] The tightening mechanism 11 is used to fix the U-shaped plate 1 in the transformer integrated distribution cabinet; specifically, the U-shaped plate 1 is placed in the position corresponding to the connecting device, and the two tightening screws 113 are screwed to drive the two fixed blocks 112 to move away from each other through their corresponding square blocks 13, and then the two fixed blocks 112 drive their corresponding tightening plates 111 to move away from each other and tighten against the left and right inner walls of the transformer integrated distribution cabinet.

[0039] See Figure 1 and Figure 4The adjusting unit 2 comprises an adjusting shaft 21 rotatably connected to the left and right ends of the U-shaped plate 1, the right end of the adjusting shaft 21 penetrates through the U-shaped plate 1 and is fixedly provided with a rotating disc 22, a plurality of sleeves 23 are uniformly and slidably arranged on the outer side of the adjusting shaft 21 between the left and right ends of the U-shaped plate 1, a plurality of adjusting plates 24 in U-shaped structure are rotatably arranged on the outer side of the sleeves 23, a distance adjusting control mechanism 25 for adjusting the distance between adjacent adjusting plates 24 is arranged at the rear end of the adjusting plates 24, and the control mechanism 25 is connected with the U-shaped plate 1.

[0040] Referring to Figure 1 , Figure 5 and Figure 7 , the clamping unit 3 comprises a square plate 31 rotatably arranged on the outer side of the sleeve 23 and located on the inner side of the adjusting plate 24, two upper and lower symmetrical connecting rods 32 are slidably arranged on the front end of the square plate 31 through a reset spring 37, a connecting plate 33 is arranged at the front end of the connecting rods 32, two upper and lower symmetrical synchronous plates 34 are slidably arranged on the front end of the connecting plate 33, two-way threaded rods 39 are arranged on the synchronous plates 34 through screwing, the two-way threaded rods 39 are rotatably connected with the connecting plate 33, arc-shaped clamping blocks 36 are fixedly arranged on the opposite sides of the synchronous plates 34 through transmission rods 35, and a twisting mechanism 38 for twisting the end of the wire is arranged on the synchronous plate 34; a square hole penetrating through the right end of the synchronous plate 34 is arranged on the lower synchronous plate 34, support rollers 331 are arranged on the middle part of the front end of the connecting plate 33, fixed plates 332 are rotatably arranged on the left end of the support rollers 331, and the fixed plates 332 are fixedly connected with the connecting plate 33.

[0041] The clamping unit 3 can stably clamp the end of the wire, the adjusting unit 2 can adjust the angle of the clamping unit 3, thereby synchronously adjusting the access angle of the end of the wire, and increasing the wiring efficiency of the transformer comprehensive power distribution cabinet connector device; specifically, first, the end of the wire is placed in the twisting mechanism 38 after passing through the square hole of the lower synchronous plate 34 and bypassing the support rollers 331, then the two-way threaded rods 39 are twisted to drive the two synchronous plates 34 to move towards each other, the synchronous plates 34 drive the two clamping blocks 36 to move towards each other through the transmission rods 35 and stably clamp the wire.

[0042] The distance between adjacent adjusting plates 24 is adjusted by the control mechanism 25, the adjusting plates 24 drive the square plate 31 to move through the sleeves 23, and finally drive the corresponding clamping blocks 36 to move, thereby adjusting the distance between the two adjacent wires at equal intervals, so that the wires can be aligned one by one with the connection of the connector, then the rotating disc 22 is twisted to drive the adjusting shaft 21 to rotate, the adjusting shaft 21 drives the clamping blocks 36 to rotate through the sleeves 23 and the square plate 31, thereby adjusting the access angle of the end of the wire.

[0043] When the access angle of the electric wire is adjusted, the clamping block 36 is driven by the connecting plate 33 to move along the axial direction of the electric wire end, so that the electric wire end is inserted into the connector, and the twisting mechanism 38 can twist and straighten the electric wire to prevent the electric wire from being bent or twisted. The electric wire and the connector are connected by manual operation, and then the two-way threaded rod 39 is screwed to drive the two synchronization plates 34 to move away from each other, so that the clamping block 36 does not clamp the electric wire. Finally, the connecting plate 33 is loosened, and the reset spring 37 drives the connecting plate 33 to return to the initial position under the action of the reset spring 37, thereby completing the connection of the connector and the electric wire.

[0044] Referring to Figure 4 , Figure 5 and Figure 7 , the right end of the U-shaped plate 1 is provided with a plurality of circumferentially uniformly distributed locking holes 12, and the right end of the rotating disc 22 is slidably installed with a locking spring rod 221 for cooperating with the locking hole 12 to lock the rotating disc 22.

[0045] When the access angles of the plurality of electric wires are the same, the locking spring rod 221 is pulled out of the locking hole 12, and the rotating disc 22 is rotated to drive the adjusting shaft 21 to rotate, thereby synchronously adjusting the access angles of the plurality of electric wires. When the access angle of the electric wire is adjusted, the locking spring rod 221 is inserted into the corresponding locking hole 12 to fix the rotating disc 22. When the access angles of the plurality of electric wires are different, the limiting spring rod 241 is pulled out of the limiting hole 311, and the square plate 31 is rotated to adjust the access angles of the electric wires individually, and the limiting spring rod 241 is inserted into the limiting hole 311 to lock the square plate 31, thereby quickly adjusting the access angles of the electric wires and further increasing the connection efficiency of the connector and the electric wire.

[0046] Referring to Figure 4 and Figure 6 , the control mechanism 25 includes a control plate 251 slidably installed on the front side of the transverse section of the U-shaped plate 1, and the control plate 251 is installed with an adjusting screw 254 in a threaded cooperation manner, and the adjusting screw 254 is rotationally connected with the U-shaped plate 1. The control plate 251 is provided with a plurality of guide grooves 252 on the front side, and the guide grooves 252 are slidably installed with guide columns 253, and the front ends of the guide columns 253 are fixedly connected with the corresponding adjusting plates 24. The lower ends of the guide grooves 252 on the left side of the control plate 251 are left inclinedly arranged, the lower ends of the guide grooves 252 on the right side of the control plate 251 are right inclinedly arranged, and the guide grooves 252 in the middle of the control plate 251 are vertically arranged.

[0047] The control mechanism 25 is used to adjust the distance between adjacent adjustment plates 24 at equal intervals, thereby achieving equal interval adjustment of the distance between adjacent wires, so that the wires can be quickly aligned with the connection points of the connectors, thereby increasing the wiring efficiency of the connector devices; specifically, screwing the adjustment screw 254 drives the control plate 251 to move downward, and the control plate 251 drives its corresponding adjustment plate 24 to move synchronously away from the middle of the control plate 251 through the guide groove 252 and the guide column 253, and the adjustment plate 24 located in the middle of the control plate 251 will not move. At the same time, under the action of the guide groove 252, the distance between the two adjacent adjustment plates 24 is always the same, and the adjustment plate 24 drives the square plate 31 to move through the sleeve 23, thereby achieving equal interval adjustment of the distance between adjacent wires.

[0048] See Figures 7-10 The torsion mechanism 38 includes a sliding plate 381 that is mounted on the side of the synchronous plate 34 near the middle of the connecting plate 33 for sliding movement forward and backward, and the sliding plate 381 is located on the front side of the transmission rod 35. The end of the sliding plate 381 near the middle of the connecting plate 33 is slidably mounted with a sliding block 383 through a connecting spring 382. The end of the sliding block 383 near the middle of the connecting plate 33 is fixedly mounted with a shift rod 384. The end of the shift rod 384 near the middle of the connecting plate 33 is slidably mounted with a torsion plate 386 through a buffer spring 385; the front ends of the two synchronous plates 34 are both slidably mounted with a yield plate 342 through the extension spring 341, and the two yield plates 342 are relative to each other. The front ends of the opposite sides are fixedly installed with roller parts 344 through square rods 343, and the rollers of the roller parts 344 are set as I-wheels, and a gear rack branch chain 387 is connected between the square rod 343 and the sliding plate 381. The gear rack branch chain 387 is used to drive the sliding plate 381 to move in the direction opposite to the moving direction of the square rod 343; the right end of the sliding block 383 is fixedly installed with an L-shaped rod 388, and the lower end of the synchronous plate 34 is fixedly installed with a corrugated plate 345 for cooperating with the vertical section of the L-shaped rod 388 to drive the sliding block 383 to move left and right, and the corrugated structures of the corrugated plates 345 corresponding to the two synchronous plates 34 arranged above and below are staggered.

[0049] It should be noted that the gear rack branch chain 387 includes a driving rack, a transmission gear, a driven rack and a rotating shaft, wherein the driving rack is arranged as an L-shaped structure, and the right end of its transverse section is fixedly connected to the left end of the square rod 343, the rear side of the right end of the driving rack is meshed with the transmission gear, and the transmission gear is connected to the rotating shaft rotatably installed on the synchronization plate 34 by a key fitting method, the right side of the transmission gear is meshed with the front side of the left end of the driven rack, and the driven rack is fixedly installed on the left end of the sliding plate 381, wherein the driving rack and the driven rack are both slidably connected to the synchronization plate 34.

[0050] The twisting mechanism 38 is used to twist the end of the wire and straighten the end of the wire, thereby preventing the insulation layer at the twisted part of the wire from being damaged to reduce the service life of the wire. Specifically, first, the end of the wire is placed between the two upper and lower arranged roller members 344. When the bidirectional threaded rod 39 drives the two synchronous plates 34 to move towards each other, the two synchronous plates 34 drive their corresponding roller members 344 to move towards each other through the square rod 343, so that the I-shaped clamps of the roller members 344 clamp the end of the wire, and the synchronous plates 34 finally drive the twisting plate 386 to move towards each other and adhere to the wire through the sliding plate 381.

[0051] When the connecting plate 33 is pushed to insert the end of the wire into the connecting part of the connector, the displacement plate 342 moves towards the synchronous plate 34 under the blocking action of the connector and compresses the top extension spring 341, and the I-shaped clamps of the roller members 344 do not block the end of the wire from being inserted into the connecting part of the connector, and when the displacement plate 342 moves towards the synchronous plate 34, the displacement plate 342 drives the sliding plate 381 to move towards the end of the wire through the square rod 343 and the gear rack branch 387, and the sliding plate 381 finally drives the twisting plate 386 to move towards the end of the wire through the sliding block 383, so that the twisting plate 386 straightens the end of the wire.

[0052] Meanwhile, the sliding block 383 moves left and right under the cooperation of the L-shaped rod 388 and its corresponding wave plate 345, and under the action of the connecting spring 382, the vertical section of the L-shaped rod 388 can always adhere to the wave structure of the wave plate 345, thereby making the sliding block 383 drive the twisting plate 386 to move left and right through the lever 384, and the wave structures of the two wave plates 345 are staggered arranged, and under the action of the buffer spring 385, the twisting plate 386 can elastically twist the end of the wire, thereby ensuring that there is no twisted part in the end of the wire.

[0055] The supporting unit 4 can support the lower end of the electric wire to leave a certain amount of electric wire, prevent the electric wire from sagging due to its own weight, cause the connection between the electric wire and the connecting device to be loose, and enable the electric wire and the connecting device to be firmly connected. Specifically, first, the two clamping plates 43 clamp the lower end of the electric wire by rotating the synchronous screw 44, when the connecting plate 33 is finally driven to rotate by the rotating disc 22 through the adjusting shaft 21, the connecting plate 33 can drive the matching rod 47 to move backward under the action of the L-shaped plate 45, at the same time, the matching rod 47 and the inclined groove 46 cooperate to drive the matching plate 42 to move downward, so that the two clamping plates 43 can always clamp the lower end of the electric wire, when the connecting plate 33 inserts the end of the electric wire into the connection of the connecting device, the connecting plate 33 drives the matching rod 47 to move forward under the action of the L-shaped plate 45, at the same time, the matching rod 47 and the inclined groove 46 cooperate to drive the matching plate 42 to move upward, thereby enabling the two clamping plates 43 to drive the lower end of the electric wire to move upward, so that the two clamping plates 43 can support the lower end of the electric wire and always leave a certain amount of electric wire, thereby enabling the electric wire to be firmly connected with the connecting device.
