[0021] Example

[0022] refer to Figures 1-5A highly stable busbar trunking system includes two adjacent busbar trunking housings 1 and a connecting component 2 disposed at the connection between the two adjacent busbar trunking housings 1. With the setting of the connecting component 2, there is no need to use bolts to align the threaded holes for fixing during installation. The installation steps are reduced, which speeds up the progress of workers splicing the busbar trunking housings 1, making the splicing of the busbar trunking housings 1 more convenient and efficient, saving time and effort, and improving work efficiency.

[0023] refer to Figures 2-3 The busbar housing 1 has L-shaped guide plates 101 symmetrically arranged on the left and right sides of the port. The bottom end face of the busbar housing 1 is fixedly connected to a snap-fit ​​plate 102, and the top end face of the busbar housing 1 is fixedly connected to an L-shaped mounting plate 103.

[0024] refer to Figures 4-5 The connecting component 2 includes an upper connecting member 21 and a lower connecting member 22. The lower connecting member 22 includes a supporting base plate 221. The top end face of the supporting base plate 221 has a snap-fit ​​groove 222 for inserting two snap-fit ​​plates 102 when connecting two adjacent busbar housings 1 end to end. The supporting base plate 221 has symmetrical supporting side plates 223 on its left and right sides. The top of the inner side wall of the supporting side plate 223 has a guide groove 224 for inserting two guide plates 101 when connecting two adjacent busbar housings 1 end to end. Through the setting of the guide groove 224 and the guide plate 101, the lower connecting member 22 can be guided and connected to the two adjacent busbar housings 1 during installation, which facilitates the initial fixed connection of the two adjacent busbar housings 1. The upper connecting member 21 includes a supporting top plate 211. The bottom of one side of the supporting top plate 211 has a snap-fit ​​groove 222 for inserting two snap-fit ​​plates 102 when connecting two adjacent busbar housings 1 end to end. The mounting slot 212, which is inserted into the mounting plate 103, not only allows the upper connector 21 and the lower connector 22 to be initially fixedly connected, but also strengthens the connection strength of the adjacent two busbar trunking shells 1. The support top plate 211 has symmetrically opened driving slots 213 at the open end. The driving slot 213 is equipped with a compression spring 214. One end of the compression spring 214 is fixedly connected to the inner side wall of the driving slot 213, and the other end of the compression spring 214 is fixedly connected to a driving column 215. The end of the driving column 215 away from the compression spring 214 extends to the outside of the driving slot 213. The end of the driving column 215 near the compression spring 214 is equipped with a limiting rod 216 that can drive the driving column 215 to move up and down. The outer side wall of the support top plate 211 is equipped with a limiting slot 217 that communicates with the driving slot 213 and allows the limiting rod 216 to move up and down.

[0025] In a further optimized design, the top end face of the support side plate 223 is symmetrically provided with a docking plate 228 that can be inserted into the mounting groove 212. The docking plate 228 on one of the support side plates 223 has a fixing groove 229 for the drive column 215 to be inserted. Through the arrangement of the fixing groove 229, the drive column 215, the compression spring 214 and the drive groove 213, the upper connecting member 21 can be limited and locked, so that the upper connecting member 21 and the lower connecting member 22 are tightly connected and fixed together, and there will be no displacement during use, which improves the stability and firmness between the adjacent two busbar trunking housings 1.

[0026] Furthermore, the support base plate 221 is symmetrically provided with a plurality of evenly distributed reinforcing blocks 225 in a triangular structure on both sides. By setting the reinforcing blocks 225, the bottom of the connection of the busbar housing 1 can be reinforced during use, so that the load-bearing capacity of the connection component 2 is higher, and the stability of the busbar housing 1 after splicing is further guaranteed.

[0027] Furthermore, a first reinforcing plate 226 is provided between two adjacent reinforcing blocks 225. The top end face of the first reinforcing plate 226 is provided with multiple reinforcing strips 227 with a triangular cross-section. The bottom end face of the busbar housing 1 is provided with a second reinforcing plate 104 corresponding to the first reinforcing plate 226. The bottom end face of the second reinforcing plate 104 is provided with reinforcing grooves 105 that correspond to and fit with the reinforcing strips 227. Through the setting of the reinforcing grooves 105 and the reinforcing strips 227, the tightness of the connection between the lower connector 22 and the bottom of the busbar housing 1 is increased, the connection strength between the two is improved, and the load-bearing capacity at the connection between two adjacent busbar housings 1 is increased.

[0028] The working principle of this utility model:

[0029] During installation, first, the two adjacent busbar housings 1 are joined end to end. The guide groove 224 on the lower connector 22 is aligned with the guide plate 101 at the connection point of the two adjacent busbar housings 1 and inserted. Simultaneously, the snap-fit ​​plate 102 at the connection point of the two adjacent busbar housings 1 is inserted into the snap-fit ​​groove 222 on the lower connector 22. The reinforcing strip 227 on the lower connector 22 is also snapped into the reinforcing groove 105 at the bottom of the busbar housing 1. At this point, the two adjacent busbar housings 1 are initially fixed together. Then, the limiting rod 216 on the upper connector 21 is pulled upwards, causing it to move within the limiting groove 217 until the drive column 215 is fully retracted into the drive groove 213. At the same time, the compression spring 214 is compressed and becomes elastic. The upper connector 21 deforms and then the mounting groove 212 on the upper connector 21 is aligned with the mounting plate 103 at the connection of the two adjacent busbar trough housings 1 and inserted. This not only makes the upper connector 21 and the lower connector 22 initially fixedly connected, but also strengthens the connection strength of the two adjacent busbar trough housings 1. At this time, the drive groove 213 on the upper connector 21 and the fixing groove 229 on the lower connector 22 are connected one by one. The limit rod 216 is released, and the compression spring 214 resets under the elastic action, driving the drive column 215 to engage with the fixing groove 229 on the lower connector 22 to limit and lock the upper connector 21. This makes the upper connector 21 and the lower connector 22 tightly connected and fixed together, and will not shift during use, thus improving the stability and firmness between the two adjacent busbar trough housings 1.

[0030] 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.

[0031] 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.
