Description

Technical Field

[0001] The invention relates to the field of transformer wiring, and in particular to a wiring fixing device for connecting components of a transformer integrated power distribution cabinet. Background Art

[0002] The transformer integrated distribution cabinet is a kind of equipment used in the power distribution system. It is usually used for the comprehensive protection, control and distribution functions of the transformer. In addition to the transformer, the transformer integrated distribution cabinet is usually equipped with connection devices such as circuit breakers, contactors and controllers. The connection devices of the transformer integrated distribution cabinet play an important role in connection, power transmission, safety protection, wiring and maintenance, and are an indispensable part of the electrical system.

[0003] Since multiple connectors usually need to be installed in the transformer integrated distribution cabinet, multiple wires need to be connected in the transformer integrated distribution cabinet. At the same time, thicker wires are often used to ensure that they can carry larger currents and prevent overheating, circuit breaking and other problems caused by overload of the wires. Therefore, when wiring the connectors of the transformer integrated distribution cabinet, a wire clamp is usually used to fix the multiple wires first, and then the wires are manually taken out of the wire clamps in turn and connected to the connectors. However, since there are many wires in the transformer integrated distribution cabinet, they are easily entangled with each other, which makes the wiring in the distribution cabinet messy and inconvenient for later maintenance.

[0004] In response to the above problems, a Chinese patent with publication number CN220172595U discloses a wiring bracket for a distribution cabinet. The patent allows the wires to pass through the branching port and, under the action of a reset spring, move the clamping block downward to clamp the wire, so that the branching port of the branching frame can place each wire separately, effectively preventing many wires from being entangled together, facilitating the maintenance of the distribution cabinet by maintenance personnel in the later stage, and at the same time using a height adjustment component to adjust the height of the branching frame so that the branching frame can better adapt to the height of the wiring.

[0005] The above technical solution still has the following problems when wiring the transformer integrated distribution cabinet connector: 1. Due to the space limitation inside the transformer integrated distribution cabinet, the wire ends need to be connected to the connector from different angles when connecting the wires, but the existing wire clamps cannot adjust the access angle of the wire ends, and the wire ends need to be manually bent, which reduces the wiring efficiency of the transformer integrated distribution cabinet connector; 2. The wires may be twisted when connected to the connector, which makes the insulation layer at the twisted part of the wire easy to be damaged, resulting in a reduced service life of the wire; 3. When the transformer integrated distribution cabinet connector is connected with thicker wires, the wires are easy to sag due to their own weight, which makes the connection between the wires and the connector easy to loosen, resulting in an unreliable electrical connection.

If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product instructions shall be followed.

[0034] See also Figure 1 and Figure 2 A wiring fixing device for a transformer integrated power distribution cabinet connection device comprises a U-shaped plate 1, both left and right ends of the U-shaped plate 1 are equipped with a clamping mechanism 11 for clamping against the inner wall of a matching cabinet, an adjusting unit 2 is installed in the U-shaped plate 1, and a plurality of clamping units 3 evenly arranged on the left and right are installed on the adjusting unit 2, and a support unit 4 for supporting electric wires is installed at the lower end of the plurality of clamping units 3, and the support unit 4 is connected to the adjusting unit 2.

[0035] The present invention can clamp a plurality of electric wires and adjust them to be at equal intervals. At the same time, the present invention can also adjust the angles of the ends of the electric wires, thereby increasing the wiring efficiency of the connecting devices of the transformer integrated power distribution cabinet. The present invention can also support the electric wires to prevent the electric wires from sagging due to their own weight, thereby preventing the connection between the electric wires and the connecting devices from loosening, so that the electric wires and the connecting devices can be securely connected.

[0036] Specifically, first, the U-shaped plate 1 is placed at the position corresponding to the connector in the transformer integrated distribution cabinet, and the two clamping mechanisms 11 are controlled 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, the lateral end of the U-shaped plate 1 and the connector are aligned left and right. Then, the end of the wire is stably clamped by the clamping unit 3, and the wire is supported by the support unit 4. 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 end of the wire. Finally, the clamping unit 3 is controlled to insert the end of the wire into the connector, and the wire and the connector are connected manually.

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

[0038] The clamping 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 at a position corresponding to the connecting device, and the two clamping screws 113 are screwed to drive the two fixed blocks 112 to move away from each other through their corresponding square blocks 13, so that the two fixed blocks 112 drive their corresponding clamping plates 111 to move away from each other and clamp against the left and right inner walls of the transformer integrated distribution cabinet. At the same time, the lateral section of the U-shaped plate 1 and the connecting device are aligned in the center left and right by controlling the movement amount of the two clamping plates 111 respectively.

[0039] See also Figure 1 and Figure 4The adjusting unit 2 includes 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 passes through the U-shaped plate 1 and is fixedly installed with a rotating disk 22. The outer side of the adjusting shaft 21 between the left and right ends of the U-shaped plate 1 is evenly slidably sleeved with a plurality of sleeves 23. The outer sides of the plurality of sleeves 23 are rotatably sleeved with adjusting plates 24 of a U-shaped structure. The rear ends of the plurality of adjusting plates 24 are jointly installed with a control mechanism 25 for adjusting the distance between adjacent adjusting plates 24 at equal intervals, and the control mechanism 25 is connected to the U-shaped plate 1.

[0040] See also Figure 1 , Figure 5 and Figure 7 The clamping unit 3 includes a square plate 31 rotatably sleeved on the outside of the sleeve 23 and located on the inside of the adjustment plate 24. The front end of the square plate 31 is slidably mounted with two connecting rods 32 symmetrically arranged up and down through a return spring 37. The front ends of the two connecting rods 32 are jointly mounted with a connecting plate 33. The front ends of the connecting plates 33 are slidably mounted with two synchronous plates 34 symmetrically arranged up and down. Both synchronous plates 34 are jointly mounted with a bidirectional threaded rod 39 through threaded matching, and the bidirectional threaded rod 39 and the connecting plate 33 are rotatably connected. The opposite sides of the two synchronous plates 34 are fixedly mounted with a clamping block 36 of an arc structure through a transmission rod 35. A twisting mechanism 38 for twisting the end of the wire is installed on the synchronous plate 34; the synchronous plate 34 below is provided with a square hole penetrating the right end of the synchronous plate 34, and a supporting roller 331 is distributed in the middle of the front end of the connecting plate 33. A fixing plate 332 is rotatably mounted on the left end of the supporting roller 331, and the fixing plate 332 and the connecting plate 33 are fixedly connected.

[0041] The clamping unit 3 can stably clamp the end of the wire, and the adjustment unit 2 can adjust the angle of the clamping unit 3, thereby realizing synchronous adjustment of the access angle of the end of the wire, thereby increasing the wiring efficiency of the connection device of the transformer integrated distribution cabinet; specifically, first, the end of the wire is passed through the square hole of the lower synchronization plate 34 and bypasses the support roller 331 and is placed in the torsion mechanism 38, and then the two-way threaded rod 39 is screwed to drive the two synchronization plates 34 to move in a direction close to each other, and the synchronization plate 34 drives the two clamping blocks 36 to move in a direction close to each other through the transmission rod 35 and stably clamps the wire.

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

[0043] When the access angle of the wire is adjusted, the clamping block 36 and the wire are driven to move along the axial direction of the wire end by pushing the connecting plate 33, so that the clamping block 36 inserts the wire end into the connector, and at the same time the twisting mechanism 38 can twist and straighten the wire to prevent the wire from bending or twisting, and manually connect the wire and the connector together, and then screw the two-way threaded rod 39 to drive the two synchronization plates 34 to move away from each other, so that the clamping block 36 no longer clamps the wire, and finally release the connecting plate 33, so that the reset spring 37 drives the connecting plate 33 through the connecting rod 32 to return to the initial position under the action of the reset spring 37, thereby completing the connection between the connector and the wire.

[0044] See also Figure 4 , Figure 5 and Figure 7 The right end of the U-shaped plate 1 is provided with a plurality of locking holes 12 evenly distributed in the circumferential direction, the right end of the rotating disk 22 is slidably installed with a locking spring rod 221 for cooperating with the locking hole 12 to lock the rotating disk 22, the right end of the square plate 31 is provided with a plurality of limiting holes 311 evenly distributed in the circumferential direction, and the right end of the adjusting plate 24 is slidably installed with a limiting spring rod 241 for cooperating with the limiting hole 311 to lock the square plate 31.

[0045] When the access angles of multiple wires are the same, the access angles of multiple wires are synchronously adjusted by pulling the locking spring rod 221 to the right out of the locking hole 12 and rotating the rotating disk 22 to drive the adjusting shaft 21 to rotate. When the access angles of the wires are adjusted, the locking spring rod 221 is inserted into the corresponding locking hole 12 to fix the rotating disk 22. When the access angles of multiple wires are different, the access angles of the wires are individually adjusted by pulling the limiting spring rod 241 out of the limiting hole 311 and rotating the square plate 31. 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 wires, further increasing the connection efficiency of the connecting device and the wires.

[0046] See also Figure 4 and Figure 6 The control mechanism 25 includes a control plate 251 slidably mounted on the front side of the transverse section of the U-shaped plate 1, the control plate 251 is installed with an adjusting screw 254 by threaded matching, and the adjusting screw 254 is rotatably connected to the U-shaped plate 1, a plurality of guide grooves 252 are opened on the front side of the control plate 251, a guide column 253 is slidably mounted in the guide groove 252, and the front end of the guide column 253 is fixedly connected to the corresponding adjustment plate 24; the lower end of the guide groove 252 located on the left side of the control plate 251 is arranged to be inclined to the left, the lower end of the guide groove 252 located on the right side of the control plate 251 is arranged to be inclined to the right, and the guide groove 252 located in the middle of the control plate 251 is arranged vertically.

[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 connectors; 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 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 also Figure 7-10 The torsion mechanism 38 includes a sliding plate 381 slidably mounted on one side of the synchronous plate 34 near the middle of the connecting plate 33, 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 lever 384. The end of the lever 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 yielding plate 342 through the extension spring 341. The two yielding plates 342 are mutually connected. 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-shaped wheels, and a gear rack branch chain 387 is connected between the square rod 343 and the sliding plate 381, and 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; an L-shaped rod 388 is fixedly installed on the right end of the sliding block 383, and a corrugated plate 345 is fixedly installed on the lower end of the synchronous plate 34 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 arranged in an alternating manner.

[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 synchronous 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 synchronous 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, which would reduce the service life of the wire. Specifically, the end of the wire is first placed between the two roller members 344 arranged upper and lower. When the two-way threaded rod 39 is screwed to drive the two synchronous plates 34 to move toward each other, the two synchronous plates 34 drive their corresponding roller members 344 to move toward each other through the square rod 343, so that the I-shaped wheel of the roller member 344 clamps the end of the wire. At the same time, the synchronous plate 34 finally drives the twisting plate 386 to move toward each other through the sliding plate 381 and fits on the wire.

[0051] When the connecting plate 33 is pushed to insert the end of the wire into the connection of the connecting device, the giving way plate 342 moves toward the direction close to the synchronous plate 34 under the blocking action of the connecting device and compresses the extension spring 341, and the I-wheel of the roller member 344 will not block the end of the wire from being inserted into the connection of the connecting device. When the giving way plate 342 moves toward the direction close to the synchronous plate 34, the giving way plate 342 drives the sliding plate 381 to move toward the direction close to the end of the wire through the square rod 343 and the gear rack branch chain 387, and the sliding plate 381 finally drives the torsion plate 386 to move toward the direction close to the end of the wire through the sliding block 383, so that the torsion plate 386 straightens the end of the wire.

[0052] At the same time, the sliding block 383 is driven to move left and right under the cooperation of the L-shaped rod 388 and its corresponding corrugated plate 345, and under the action of the connecting spring 382, ​​the vertical section of the L-shaped rod 388 can always fit on the corrugated structure of the corrugated plate 345, so that the sliding block 383 drives the torsion plate 386 to move left and right through the lever 384, and the corrugated structures of the two corrugated plates 345 are arranged in an alternating manner, and under the action of the buffer spring 385, the torsion plate 386 can elastically twist the end of the wire, thereby ensuring that there is no twisted part at the end of the wire.

[0053] See also Figure 7 and Fig.11 The support unit 4 includes two guide rods 41 fixedly mounted at the lower end of the transverse section of the adjustment plate 24 and arranged symmetrically on the left and right sides. A U-shaped matching plate 42 is slidably sleeved on the outer sides of the two guide rods 41. Two clamping plates 43 arranged symmetrically on the left and right sides are slidably mounted on the front end of the transverse section of the matching plate 42. Both clamping plates 43 are jointly mounted with a synchronous screw 44 by means of threaded matching, and the synchronous screw 44 and the matching plate 42 are rotatably connected.

[0054] The support unit 4 also includes a matching rod 47 hinged at the lower end of the connecting plate 33, the upper end of the matching rod 47 is arranged as a telescopic structure, an L-shaped plate 45 is provided on the outer side of the fixed end of the matching rod 47 for front and rear sliding sleeve, and the vertical section of the L-shaped plate 45 is fixedly connected to the adjustment plate 24, the left and right inner walls of the matching plate 42 are provided with inclined grooves 46 with the front end tilted downward, and the lower end of the matching rod 47 is slidably installed in the inclined grooves 46.

[0055] The support unit 4 can support the lower end of the wire so that the wire has a certain margin, preventing the wire from sagging due to its own weight and causing the connection between the wire and the connecting device to become loose, so that the wire and the connecting device can be firmly connected; specifically, firstly, the two clamping plates 43 are driven to clamp the lower end of the wire by screwing the synchronous screw 44, and when the screwing rotating disk 22 finally drives the connecting plate 33 to rotate 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, and at the same time, the matching rod 47 and the inclined groove 46 cooperate to drive The mating plate 42 moves downward so that the two clamping plates 43 can always clamp the lower end of the wire. When the connecting plate 33 is pushed to insert the end of the wire into the connection of the connector, the connecting plate 33 drives the mating rod 47 to move forward under the action of the L-shaped plate 45. At the same time, the mating rod 47 and the inclined groove 46 cooperate to drive the mating plate 42 to move upward, thereby causing the two clamping plates 43 to drive the lower end of the wire to move upward, so that the two clamping plates 43 can support the lower end of the wire and allow the wire to always have a certain margin, thereby allowing the wire to be firmly connected to the connector.
