Description

Technical Field

[0001] This utility model relates to the field of copper busbar lap joint technology, and in particular to a copper busbar lap joint structure and its copper busbar assembly. Background Technology

[0002] Copper busbars, generally referring to copper busbars, are indispensable conductive materials in the manufacture of motor windings, high and low voltage electrical appliances, switch contacts, and conductors for power supply and distribution installations. Copper busbars are a major type of copper processed material. They possess high mechanical properties, good electrical and thermal conductivity, excellent corrosion resistance, electroplating and brazing properties, a beautiful metallic luster, and good formability and processing performance. Therefore, various power transmission and transformation equipment and electrical systems made from copper busbars are widely used in the power industry.

[0003] A copper busbar overlapping structure is disclosed in Chinese Patent CN221806080U. Research on existing technology and the aforementioned patent reveals that most copper busbar overlapping uses a fixed overlapping method, meaning the relative positions of the two copper busbars cannot change. In this case, when the copper busbar is subjected to external loads, the overlapping joint is prone to breakage, causing the copper busbar's operation to be interrupted. Therefore, this utility model proposes a copper busbar overlapping structure and its assembly. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a copper busbar overlapping structure and its copper busbar assembly.

[0006] The purpose of this utility model is achieved through the following technical solution: a copper busbar overlapping structure and its copper busbar assembly, including a first copper busbar, a connecting groove is provided at each of the four corners of the first copper busbar, a positioning groove is provided on the side of the first copper busbar near the connecting groove, a positioning block is engaged inside the positioning groove, a connecting block is fixedly connected to one side of the positioning block, and a second copper busbar is fixedly connected to the top of the positioning block.

[0007] Preferably, both the first and second copper busbars have through holes at their centers, and bolts are inserted into the through holes. Nuts are threaded onto both ends of the bolts.

[0008] By adopting the above technical solution, the bolt passes through the through hole, and the two ends of the bolt are fixedly connected by nuts, thereby connecting the first copper busbar and the second copper busbar into one unit.

[0009] Preferably, the end of the bolt is fitted with a base, the base is in contact with the bottom surface of the first copper busbar, the base is in contact with the top surface of the second copper busbar, and a heat dissipation column is provided at the center of the base.

[0010] By adopting the above technical solution, multiple bases are equipped with heat dissipation columns to dissipate heat from the copper busbars.

[0011] Preferably, the connecting groove is a rectangular groove, the positioning groove is a semi-circular groove, the connecting groove and the positioning groove are connected, the diameter of the positioning groove is greater than the length of the connecting groove, and the depth of the connecting groove is the same as the depth of the positioning groove.

[0012] By adopting the above technical solution, when the positioning block is engaged in the positioning groove, because the size of the positioning groove is larger than the size of the connecting groove, the positioning block cannot move laterally out of the connecting groove, which can prevent the two copper busbars from being misaligned when subjected to external force load.

[0013] Preferably, there are four connecting blocks, which are located at the two corners on the left and right sides of the second copper busbar. The connecting blocks are welded to the center of one side of the positioning block, and the thickness of the connecting blocks is the same as the thickness of the positioning block.

[0014] Preferably, the thickness of the positioning block is the same as the depth of the positioning groove, and the thickness of the connecting block is the same as the depth of the connecting groove.

[0015] By adopting the above technical solution, the snap-fit ​​method allows two copper busbars to be quickly connected, and the through holes of the two copper busbars are naturally aligned.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This copper busbar overlapping structure and its copper busbar assembly, by setting positioning blocks, has a positioning groove on the side of the first copper busbar near the connecting groove, and a positioning block is snapped into the inside of the positioning groove. A connecting block is fixedly connected to one side of the positioning block, and a second copper busbar is fixedly connected to the top of the positioning block. During installation, the positioning block and connecting block on one side of the second copper busbar are inserted into the connecting groove and positioning groove on one side of the first copper busbar, respectively, and the two copper busbars are initially connected. The bolts pass through the through holes, and the two ends of the bolts are fixedly connected by nuts, so that the first copper busbar and the second copper busbar can be connected as one unit. When the positioning block is snapped into the positioning groove, because the size of the positioning groove is larger than the size of the connecting groove, the positioning block cannot move laterally out of the connecting groove, which can prevent the two copper busbars from being misaligned when subjected to external loads.
