[0002] Busbar trunking is a closed metal device made of copper or aluminum busbar columns, used to distribute large amounts of power to various components in a distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. As a functional unit of the power transmission busbar trunking, the plug-in box plays a role in power distribution in the busbar trunking system. As the requirements for the performance and reliability of busbar trunking products become higher and higher, the requirements for the safety, reliability and ease of operation of plug-in boxes are also becoming higher and higher.

[0003] However, existing plug-in boxes do not have a branching structure, which makes it inconvenient for operators to organize the wiring and for maintenance, causing inconvenience during use. In addition, existing plug-in boxes do not have a heat dissipation structure, and the heat accumulation caused by long-term use will reduce the lifespan of electrical components inside the plug-in box, making it inconvenient to use. Therefore, there is an urgent need for a branching device for busbar plug-in boxes to solve the above problems. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides an embodiment of a busbar trunking plug-in box branching device, including a plug-in box body 1, a heat dissipation structure 2, and a branching structure 3. The heat dissipation structure 2 includes a filter screen 21 and a cooling fan 22. The filter screen 21 and the cooling fan 22 are fixedly connected to the inner wall of the right side of the plug-in box body 1. The branching structure 3 includes a base 31, a first clamping plate 34, and a second clamping plate 311. Six bases 31 are fixedly connected to the inner wall of the plug-in box body 1. The top of the base 31 is fixedly connected to the first clamping plate 34. The first clamping plate 34 is slidably connected to a slide rod 39. The top of the slide rod 39 is fixedly connected to a limiting plate 310. The slide rod 39 is slidably connected to the second clamping plate 311. The second clamping plate 311 is threadedly connected to a threaded rod 37. The threaded rod 37 is rotatably connected to the first clamping plate 34.

[0023] Furthermore, both ends of the base 31 are threaded with fixing bolts 32, which are threaded to the inner wall of the plug box body 1. The branch structure 3 is fixed inside the plug box body 1 by fixing bolts 32.

[0024] Furthermore, two support rods 33 are fixedly connected to the top of the base 31, and clamping plate 34 is fixedly connected to the top of the two support rods 33, so that clamping plate 34 is supported by the support rods 33.

[0025] Furthermore, fixing plates 35 are fixedly connected to both sides of the clamping plate 34. The fixing plate 35 at the left end is slidably connected to the slide rod 39, and the fixing plate 35 at the right end is rotatably connected to the rotating shaft 36.

[0026] Furthermore, a threaded rod 37 is fixedly connected to the top of the rotating shaft 36, and a hand-tightening nut 38 is fixedly connected to the top of the threaded rod 37. The surface of the hand-tightening nut 38 is provided with uneven patterns. Rotating the hand-tightening nut 38 causes the hand-tightening nut 38 to drive the threaded rod 37 to rotate, and the threaded rod 37 drives the clamping plate 311 to move downward.

[0027] Furthermore, fixing plates 312 are fixedly connected to both the left and right sides of clamping plate 311. The fixing plate 312 at the left end is slidably connected to sliding rod 39, and the fixing plate 312 at the right end is threadedly connected to threaded rod 37.

[0028] Furthermore, rubber pads 313 are fixedly connected to the inner walls of clamping plate 34 and clamping plate 311. The inner wall of the rubber pad 313 is provided with uneven texture. The rubber pad 313 can increase the friction during clamping, thereby improving the stability of clamping plate 34 and clamping plate 311, and preventing damage to the wiring when clamping plate 34 and clamping plate 311.

[0029] Working principle:

[0030] In use, when it is necessary to fix the wiring of the connector box body 1, the wiring is passed between clamp 1 34 and clamp 2 311. The hand-tightening nut 38 is turned, causing the threaded rod 37 to rotate. The threaded rod 37 then moves clamp 2 311 downwards. Clamp 2 311 moves downwards along the slide rod 39, improving the stability of clamp 2 311 during movement. This allows clamp 1 34 and clamp 2 311 to clamp the wiring. The rubber pad 313 increases the friction during clamping, thereby improving the stability of clamp 1 34 and clamp 2 311. The second clamp 311 provides stability during clamping and prevents damage to the wiring when clamped by the first clamp 34 and the second clamp 311. The wiring can be clamped through the branch structure 3, which helps the operator to sort out the wiring, facilitates maintenance, and makes it easy to use. The filter screen 21 can filter the air entering the plug box body 1 to prevent dust from entering the plug box body 1 and causing damage to electrical components. The cooling fan 22 can draw in outside air, which improves the heat dissipation performance of the plug box body 1 and helps to extend the service life of the equipment.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
