Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically to a busbar connection structure that is easy to maintain. Background Technology

[0002] With the emergence of modern engineering facilities and equipment, the electricity consumption of various industries has increased rapidly. In particular, with the emergence of numerous high-rise buildings and large factory workshops, traditional cables, as power transmission conductors, can no longer meet the requirements of high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction. Busbar trunking, as a new type of power distribution conductor, has emerged. Due to its small capacity, inconvenient branching, and difficulty in bundled management, the original wires and cables have been gradually replaced by busbar trunking, which has a large capacity, convenient branching, and convenient bundled management.

[0003] After busbar trunking is connected via connectors, the exposed busbars at the connection point are susceptible to environmental influences. Dust or moisture can easily accumulate on the surface of the busbars at the connection point. A common solution is to install a sealing plate around the connection point and fix the sealing plate with multiple bolts to shield the connection point of the busbar trunking. However, during installation, the bolts need to be tightened one by one, and during subsequent disassembly and maintenance, the bolts need to be loosened one by one. The operation is cumbersome and inconvenient. Utility Model Content

[0025] Example

[0026] refer to Figures 1-3 A busbar trunking connection structure that is easy to maintain includes a busbar trunking housing 1 and a shielding assembly 2 disposed at the connection between two adjacent busbar trunking housings 1. The shielding assembly 2 includes a shielding cover plate 21. Shielding side plates 22 are symmetrically disposed on both sides of the shielding cover plate 21 on both sides of the busbar trunking housing 1. A connecting plate 221 extending along the length direction of the shielding side plate 22 is disposed at the bottom of the outer side wall of the shielding side plate 22. A shielding bottom plate 23 is detachably disposed between the bottoms of the two shielding side plates 22. Extension plates 231 located outside the shielding side plates 22 are disposed on both sides of the top end face of the bottom plate 23. A fixing mechanism 3 is disposed on the top end face of the extension plate 231.

[0027] Furthermore, the top end faces of both ends of the busbar housing 1 are provided with connecting rods 101, and the shielding cover plate 21 is provided with connecting holes 211 for inserting the connecting rods 101 on the two busbar housings 1 when the two adjacent busbar housings 1 are connected end to end. Through the setting of connecting rods 101 and connecting holes 211, the initial connection between the shielding cover plate 21, the shielding side plate 22 and the two busbar housings 1 is realized.

[0028] Furthermore, a connecting groove 232 is provided through the extension plate 231 for the connecting plate 221 to be inserted. Through the setting of the connecting plate 221 and the connecting groove 232, the initial docking of the shielding bottom plate 23 and the two shielding side plates 22 is realized.

[0029] Furthermore, a stop plate 222 is provided on one side of the top end face of the connecting plate 221, and a stop groove 233 that fits with the stop plate 222 is provided on one end of the extension plate 231. The stop plate 222 can limit the displacement of the shielding base plate 23 to ensure that the first fixing hole 234 of the shielding base plate 23 is aligned with the second fixing hole 223 of the connecting plate 221.

[0030] refer to Figures 4-6 The fixing mechanism 3 includes a support block 301, a sliding groove 302 is provided in the support block 301, a connecting plate 303 is slidably connected in the sliding groove 302, a fixing rod 304 is provided on the bottom end face of the connecting plate 303 extending to the outside of the bottom of the support block 301, the fixing rod 304 is slidably connected to the bottom of the support block 301, a connecting rod 305 is provided on the top end face of the connecting plate 303 extending to the outside of the top of the support block 301, the connecting rod 305 is slidably connected to the top of the support block 301, and a drive assembly 4 is rotatably connected to the end of the connecting rod 305 away from the connecting plate 303 through a movable base 306, and a spring 307 located in the sliding groove 302 is sleeved on the outside of the connecting rod 305.

[0031] Furthermore, the extension plate 231 is provided with a first fixing hole 234 for inserting the fixing rod 304, and the connecting plate 221 is provided with a second fixing hole 223 for inserting the fixing rod 304. By inserting the fixing rod 304 into the first fixing hole 234 and the second fixing hole 223, the shielding base plate 23 is fixedly installed between the bottoms of the two shielding side plates 22, ensuring that the shielding assembly 2 is stably installed at the junction of the two busbar trunkings, thereby achieving all-round shielding at the junction of the two busbar trunkings.

[0032] Furthermore, the drive assembly 4 includes a drive plate 401, a locking rod 402 symmetrically provided on the bottom end face of the drive plate 401, and a drive handle 403 provided on the top end face of the drive plate 401, the drive handle 403 having a U-shaped structure with the opening facing downward.

[0033] Furthermore, each of the support blocks 301 on both sides of the drive plate 401 is provided with a limiting post 308. The limiting post 308 is provided with a rotating groove 309 that allows the drive plate 401 and the locking rod 402 to rotate. The two rotating grooves 309 on the two limiting posts 308 have opposite opening directions, thereby limiting the rotation of the drive plate 401. The bottom of the rotating groove 309 is provided with a locking groove 310 that allows the locking rod 402 to engage.

[0034] The working principle of this utility model:

[0035] During installation, first, align the mating holes 211 on the cover plate 21 with the mating rods 101 at the connection points of the adjacent two busbar trough housings 1 and insert them. During insertion, the shielding side plates 22 are inserted into both sides of the busbar trough housing 1, thereby shielding the top and sides of the connection point between the two busbar troughs with the cover plate 21 and the shielding side plates 22. Then, pull the drive handle 403 upward. The drive handle 403 drives the connecting rod 305, the connecting plate 303, and the fixing rod 304 to move upward synchronously, compressing the spring 30. 7. When the drive plate 401 moves to the rotation groove 309 of the limiting post 308, rotate the drive handle 403 counterclockwise to make the drive plate 401 and the locking rod 402 rotate and move into the rotation groove 309. Then release the drive handle 403. The elastic potential energy of the spring 307 makes the locking rod 402 engage in the locking groove 310 of the limiting post 308. At this time, the fixing rod 304 is completely retracted into the support block 301, which does not hinder the subsequent insertion of the connecting plate 221 into the connecting groove 232. Next, cover the bottom plate 2. The connecting slot 232 of the shielding side plate 22 is inserted into the connecting plate 221 of the shielding side plate 22, thereby shielding the bottom of the two busbar grooves at the joint of the shielding bottom plate 23. The stop plate 222 on the connecting plate 221 can limit the displacement of the shielding bottom plate 23 to ensure that the first fixing hole 234 of the shielding bottom plate 23 is aligned with the second fixing hole 223 of the connecting plate 221. Then, pull the drive handle 403 upward to disengage the locking rod 402 from the locking slot 310 of the limiting post 308, and rotate the drive handle clockwise. 403, disengage the drive plate 401 and locking rod 402 from the rotating groove 309, then release the drive handle 403. The spring 307 returns to its original state, driving the connecting rod 305, connecting plate 303 and fixing rod 304 to reset. This causes the fixing rod 304 to be inserted into the first fixing hole 234 and the second fixing hole 223, thereby fixing the shielding base plate 23 between the bottoms of the two shielding side plates 22. This ensures that the shielding assembly 2 is stably installed at the junction of the two busbars, thus achieving all-round shielding at the junction of the two busbars.
