Technical Field

[0001] This utility model relates to the field of wiring device technology, specifically a wiring device for high-voltage switchgear. Background Technology

[0002] High-voltage switchgear consists of indoor and outdoor AC switchgear operating in power systems. It is primarily used for the control and protection of power systems. It can be used to put into or take off certain power equipment or lines as needed for grid operation, and it can also quickly disconnect faulty parts of power equipment or lines from the grid when a fault occurs, thereby ensuring the normal operation of fault-free parts of the grid and the safety of equipment, operation, and maintenance personnel.

[0003] A previously published patent (publication number CN218275548U) discloses a wiring device for a high-voltage switchgear, including a junction box. The junction box has an input line connection port and an output line connection port. The junction box has several fixed seats, and an arc-shaped clamp rotates on the fixed seats. The junction box also has several cylindrical rods, and a sliding rod slides inside the cylindrical rods. The junction box has outlets on both sides, and several first elastic clamps are fixedly installed in each of the two outlets. A wire take-up device is fixedly installed outside one of the outlets. The wire take-up device has several rotating rods, and a first baffle and a second baffle are respectively installed at both ends of the rotating rods. A rotary switch is fixedly connected to the wire take-up device through the rotating rods. This utility model uses arc-shaped clamps, arc-shaped buckles, first elastic clamps, and second elastic clamps to organize the input and output lines, avoiding the phenomenon of wires getting tangled together.

[0004] However, existing wiring devices have some problems in use: 1. Existing wiring devices are not convenient for adjusting the limiting size, and can only limit the length of the connection. However, due to the different materials of the wires, even a shorter length limit can still cause the wire to bend and break during use, affecting the safety of the wiring. 2. Furthermore, existing wiring devices have fixed wire limiting clamp sizes, which cannot securely and stably clamp and limit wires of different diameters, affecting the versatility of the wiring device. Utility Model Content

[0005] The purpose of this utility model is to provide a wiring device for high-voltage switchgear to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including an equipment box, a wiring port disposed on the upper inner front surface of the equipment box, a clamping component disposed on the surface of the equipment box at the lower side of the wiring port, and a clamping component disposed on the lower side of the clamping component;

[0007] The clamping assembly includes a base plate disposed on the front surface of the equipment box at the lower side of the wiring port, a pressure groove is provided between the base plates, and telescopic grooves are provided inside the left and right sides of the base plate. A telescopic plate is movably disposed inside the front side of the telescopic groove, and a pressure plate is disposed on the front surface of the telescopic plate.

[0008] The clamping assembly includes a top groove inside the upper end of the telescopic plate, a first bevel gear is provided on the inner wall of the top groove away from the center of the pressure groove, a knob is connected to the outer end of the first bevel gear, and a second bevel gear is provided on the inner wall of the lower end of the top groove to cooperate with the first bevel gear.

[0009] As a further improvement of this utility model: the side wall of the telescopic groove is provided with a side groove, and the side wall of the telescopic plate is provided with a side plate that cooperates with the side groove.

[0010] As a further improvement of this utility model: a telescopic rod is provided on the front surface of the side plate, and a spring is fitted onto the outer wall of the telescopic rod.

[0012] As a further improvement of this utility model: the side wall of the slide groove is provided with a limiting groove, and the side wall of the slide plate is provided with a limiting plate that cooperates with the limiting groove.

[0013] As a further embodiment of this invention, the rotation input end of the screw is connected to the rotation output end of the second bevel gear.

[0014] As a further improvement of this utility model, the cross-sectional dimensions of the telescopic plate are matched with the cross-sectional dimensions of the telescopic groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] When different materials of wiring need to be connected, this utility model requires a longer arrangement dimension for wiring that is more easily bent. Twisting the knob drives the first bevel gear connected to it to rotate, which in turn drives the second bevel gear to rotate, which in turn drives the screw connected to it to rotate. Through the threaded engagement on the outer wall, the sliding plate of the set is driven to slide downward in the sliding groove. With the limiting plate embedded in the limiting groove, the clamping ring is driven to steadily increase the distance between itself and the pressure plate, thereby achieving a longer vertical arrangement effect for wiring of softer materials.

[0017] When the wiring needs to be tidied and pressed, the present invention pulls the pressure plate forward, causing the telescopic plate to move and extend away from the seat plate in the telescopic groove, causing the side plate to slide in the side groove, compressing the telescopic rod and spring to retract, placing the wiring between the clamping rings and simultaneously placing it in the pressure groove, inserting the wiring end into the wiring port, releasing the tension on the pressure plate, the telescopic rod and spring push the side plate backward, causing the telescopic plate to slide into the telescopic groove, causing the pressure plate to press the wiring backward, and at the same time, the wiring is clamped backward by the clamping ring on the lower side, so that the wiring is firmly and stably held vertically in the pressure groove, ensuring that the wiring at the wiring port is flat and avoiding bending or breakage of the wiring.

[0023] To facilitate the solution of the problem, this utility model provides a wiring device for high-voltage switchgear. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example 1

[0025] like Figures 1 to 4As shown, this embodiment provides a wiring device for a high-voltage switchgear, including a device box 1, a wiring port 2 disposed on the upper inner front surface of the device box 1, a clamping assembly disposed on the surface of the device box 1 at the lower side of the wiring port 2, and a clamping assembly disposed on the lower side of the clamping assembly.

[0026] The clamping assembly includes a base plate 301 disposed on the front surface of the equipment box 1 at the lower side of the connection port 2, a pressure groove 302 is provided between the base plates 301, and telescopic grooves 303 are provided inside the left and right sides of the base plates 301. A telescopic plate 304 is movably disposed inside the front side of the telescopic groove 303, and a pressure plate 309 is provided on the front surface of the telescopic plate 304.

[0027] The clamping assembly includes a top groove 401 opened inside the upper end of the telescopic plate 304. A first bevel gear 402 is provided on the inner wall of the top groove 401 away from the center of the pressure groove 302. A knob 403 is connected to the outer end of the first bevel gear 402. A second bevel gear 404 is provided on the inner wall of the lower end of the top groove 401, which cooperates with the first bevel gear 402.

[0028] Example 2

[0029] As a further embodiment of this utility model, the side wall of the telescopic groove 303 is provided with a side groove 305, and the side wall of the telescopic plate 304 is provided with a side plate 306 that cooperates with the side groove 305. Pulling the pressure plate 309 forward causes the telescopic plate 304 to move and extend away from the seat plate 301 in the telescopic groove 303, causing the side plate 306 to slide in the side groove 305, compressing the telescopic rod 307 and the spring 308 to make them contract.

[0030] Furthermore, a telescopic rod 307 is provided on the front surface of the side plate 306. A spring 308 is fitted on the outer wall of the telescopic rod 307. The telescopic rod 307 and the spring 308 are squeezed together to retract, placing the wire between the clamping rings 410 and simultaneously placing it in the pressure groove 302. The wire end is inserted into the wire port 2. The tension on the pressure plate 309 is released, and the telescopic rod 307 and the spring 308 push the side plate 306 backward, causing the telescopic plate 304 to slide into the telescopic groove 303, which in turn causes the pressure plate 309 to press the wire backward.

[0031] Furthermore, a sliding groove 405 is provided on the lower outer side of the top groove 401. A screw 406 is provided inside the sliding groove 405. A sliding plate 407 is fitted on the outer wall of the screw 406. A clamping ring 410 is provided on the lower side wall of the sliding plate 407. The pressure plate 309 presses the wire backward, and at the same time, the clamping ring 410 on the lower side clamps the wire backward, so that the wire is firmly and stably held vertically in the pressure groove 302, ensuring that the wire at the wire connection 2 is flat and avoiding bending or breakage of the wire.

[0032] Furthermore, the slide 405 has a limiting groove 408 on its side wall, and the slide plate 407 has a limiting plate 409 that cooperates with the limiting groove 408 on its side wall. When the limiting plate 409 is embedded in the limiting groove 408, it drives the clamping ring 410 to steadily increase the distance between it and the pressure plate 309 downward.

[0033] As a further embodiment of this utility model, the rotation input end of the screw 406 is connected to the rotation output end of the second bevel gear 404. When the second bevel gear 404 rotates, it drives the screw 406 connected to it to rotate. Through the thread engagement provided on the outer wall, it drives the fitted slide plate 407 to slide downward in the slide groove 405.

[0034] Furthermore, the cross-sectional dimensions of the telescopic plate 304 are matched with the cross-sectional dimensions of the telescopic groove 303. Pulling the pressure plate 309 causes the telescopic plate 304 to move and extend away from the seat plate 301 within the telescopic groove 303. The telescopic plate 304 slides into the telescopic groove 303, causing the pressure plate 309 to press the wire backward. At the same time, the wire is clamped backward by the clamping ring 410 on the lower side, so that the wire is firmly and stably held vertically within the pressure groove 302.

[0035] Working principle: When different materials of wiring need to be connected, a longer adjustment dimension is required for wiring that is easier to bend. Twisting knob 403 rotates the first bevel gear 402 connected to it, which in turn rotates the second bevel gear 404, which in turn rotates the screw 406 connected to it. Through the threaded engagement on the outer wall, the sliding plate 407 is driven to slide downward in the slide groove 405. Under the limitation of the limiting plate 409 embedded in the limiting groove 408, the clamping ring 410 is driven to steadily increase the distance between itself and the pressure plate 309, thereby achieving a longer vertical adjustment effect for wiring of softer materials. When it is necessary to adjust and press the wiring, pulling the pressure plate 309 forward drives the telescopic plate 3... 04. The telescopic rod 307 extends outward from the seat plate 301 within the telescopic groove 303, causing the side plate 306 to slide within the side groove 305. This compresses the telescopic rod 307 and spring 308, causing them to contract. The wire is placed between the clamping rings 410 and simultaneously placed within the pressure groove 302. The wire end is inserted into the wire port 2. The tension on the pressure plate 309 is released, and the telescopic rod 307 and spring 308 push the side plate 306 backward, causing the telescopic plate 304 to slide into the telescopic groove 303. This causes the pressure plate 309 to compress the wire backward, while simultaneously clamping the wire together with the clamping rings 410 on the lower side. This ensures that the wire is firmly and stably held vertically within the pressure groove 302, guaranteeing that the wire at the wire port 2 is flat and preventing bending or breakage.
