Abstract
Description
Technical Field
[0001] This utility model relates to the field of busbar technology, specifically a novel busbar connection structure. Background Technology
[0002] Busbar trunking is a closed metal device made of copper or aluminum busbars, used to distribute large amounts of power to various components in a distributed system. It is increasingly replacing electrical wires and cables in indoor low-voltage power transmission trunk line projects. It is widely used in developed countries, as well as in Hong Kong and Macau. In Guangzhou, Guangdong Province, my country, over 90% of the main power lines leading from the distribution room to the floors of buildings with 12 or more floors use busbar trunking; busbar trunking is also required from 630KVA transformers to distribution cabinets.
[0003] Electrical connections between busbar trunking systems are achieved through busbar trunking connectors. After the electrical connection is completed, other connection structures are needed (connector connections have poor stability). Cover plates are commonly used for connection. The installation of cover plates helps maintain the structural integrity of the entire busbar trunking system, playing a role in fixing and reinforcing, and can also prevent dust from entering the connectors. However, different models of connectors have different lengths, resulting in different distances between the two busbar trunking systems connected electrically. Cover plates are generally fixed between the two busbar trunking systems with screws (the mounting holes are pre-drilled), and the installation length is fixed, which makes them unsuitable for different models of connectors, resulting in poor practicality of the connection structure. Utility Model Content
[0004] The purpose of this invention is to provide a novel busbar trunking connection structure for existing devices, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A novel busbar trunking connection structure includes a busbar trunking housing and a cover plate connected between the tops of two busbar trunking housings. A hollow groove is formed through the cover plate. Auxiliary cover plates are slidably provided at both ends of the hollow groove. A traveling toothed plate is provided on the auxiliary cover plate and located in the hollow groove. A locking seat is provided at the end of the auxiliary cover plate away from the cover plate. A movable groove is formed in the locking seat. A guide rod is provided in the movable groove and connected to its inner sidewall at both ends. Two movable plates are slidably connected to the guide rod. A return spring is sleeved on the outside of the guide rod between the two movable plates. A locking plate is provided at the bottom of the movable plate. A toggle rod extending to the outside of the locking seat is provided at the top of the movable plate. A gear that meshes with the two traveling toothed plates is provided in the hollow groove. The bottom of the gear is rotatably connected to the cover plate.

[0023] Example
[0024] refer to Figures 1-6A novel busbar trunking connection structure includes a busbar trunking housing 1 and a cover plate 2 connecting the tops of two busbar trunking housings 1. A hollow groove 201 is formed through the cover plate 2. Auxiliary cover plates 3 are slidably provided at both ends of the hollow groove 201. Each auxiliary cover plate 3 has a traveling toothed plate 301 located within the hollow groove 201. The two traveling toothed plates 301 are arranged parallel to each other. A locking seat 302 is provided at the end of the auxiliary cover plate 3 away from the cover plate 2. A movable groove 303 is formed within the locking seat 302. A guide rod 304, with both ends connected to its inner sidewall, is provided within the movable groove 303. A slidably connected guide rod 304 is mounted on the guide rod 304. Two movable plates 305 are provided, and a return spring 306 is sleeved on the outside of the guide rod 304 between the two movable plates 305. The guide rod 304 can guide the displacement of the two movable plates 305 and make the displacement of the movable plates 305 more stable. A locking plate 307 is provided at the bottom of the movable plate 305, and an actuating rod 308 extending to the outside of the locking seat 302 is provided at the top of the movable plate 305. A gear 202 that meshes with the two traveling gear plates 301 is provided in the hollow groove 201. The bottom of the gear 202 is rotatably connected to the cover plate 2, and the top of the gear 202 is provided with a drive rod 203 extending to the outside of the top of the cover plate 2.
[0025] refer to Figure 2 The busbar housing 1 has a docking block 101 at both ends of the top. The docking block 101 has a locking groove 102 that allows the locking plate 307 to be inserted. By setting the locking groove 102 and the locking plate 307, the auxiliary cover plate 3 is locked on the busbar housing 1, thereby making the extended and adjusted auxiliary cover plate 3 and cover plate 2 fixedly installed between the tops of the two busbar housings 1.
[0026] Furthermore, the locking seat 302 has a through-hole for the locking plate 307 to slide and move, and the through-hole 309 is connected to the movable groove 303.
[0027] Furthermore, the top of the locking seat 302 is provided with a displacement groove 310 that allows the toggle lever 308 to move.
[0028] Furthermore, a track groove 204 is provided on the inner side wall of the hollow groove 201, and an assembly groove 311 is provided through the auxiliary cover plate 3 located in the hollow groove 201. A roller 312 adapted to the track groove 204 is rotatably connected in the assembly groove 311. The arrangement of the roller 312 and the track groove 204 makes the extension and retraction displacement of the auxiliary cover plate 3 easier, more convenient and stable.
[0029] Furthermore, the auxiliary cover plate 3 is provided with L-shaped connecting plates 313 symmetrically on both sides of the end away from the cover plate 2. The inner side wall of the connecting plate 313 is provided with reinforcing blocks 314, and the outer side wall of the cover plate 2 is provided with reinforcing grooves 205 that allow the reinforcing blocks 314 to move. Through the arrangement of the reinforcing blocks 314 and the reinforcing grooves 205, the connection strength between the auxiliary cover plate 3 and the cover plate 2 is strengthened.
[0030] The working principle of this utility model:
[0031] During installation, the two levers 308 within the locking seat 302 are moved closer together. The levers 308 cause the two movable plates 305 to move closer together and compress the return spring 306. The return spring 306 undergoes elastic deformation until the locking plate 307 is completely housed within the locking seat 302. Then, the drive rod 203 is rotated to rotate the gear 202. The gear 202 meshes with the traveling gear plates 301 on both sides, thereby driving the two traveling gear plates 301 to move in opposite or opposite directions. The two traveling gear plates 301 simultaneously move the two auxiliary cover plates 3 away from each other or towards each other. The plates move closer to each other until the locking seat 302 is inserted between the two mating blocks 101. Then, the drive rod 203 stops rotating and the lever 308 is released. The return spring 306 restores its deformation and converts the elastic potential energy into kinetic energy, which reacts on the two movable plates 305, causing the two movable plates 305 to move away from each other. The movable plates 305 drive the locking plate 307 to move synchronously, so that the locking plate 307 is inserted into the locking groove 102, thereby locking the auxiliary cover plate 3 onto the busbar housing 1. This allows the extended and adjusted auxiliary cover plate 3 and cover plate 2 to be fixedly installed between the tops of the two busbar housings 1.
[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0033] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
