[0043] like Figure 2 As shown, the connector 1 further includes a positioning end 21 and a copper busbar 31 . The connection end 11 and the positioning end 21 are integrally formed by plastic coating. The connection end 11 is connected to the copper busbar 31 , and the copper busbar 31 is passed through the positioning end 21 .

[0044] like Figure 2 As shown, the positioning end 21 is provided with at least two positioning pins 22. More specifically, the positioning pins 22 provided on the positioning end 21 can be provided in an area of ​​the positioning end 21 where no contact parts are provided with the box body 4, and can be provided according to the structure of the actual application product. The box body 4 is provided with a fixing hole according to the structure of the positioning pins 22, and the positioning pins 22 are inserted into the fixing holes located on the box body 4. In the process of fixing the connector 1 to the box body 4 (i.e., as shown in FIG. 1 ), the positioning pins 22 are provided on the positioning end 21. Figure 5 As shown), the positioning pin 22 plays a fixing role, improves the positioning efficiency and saves costs.

[0052] The specific structure of the connector 1 is as follows: Figure 5 As shown, it can be seen from the figure that one end of the connecting end 11 of the connector 1 is connected to the wire nose 5. The wire nose 5 selects a direction and is fixed by the limiter 12 and the blocking member 13, and then extends out from the limited area. The wire nose 5 and the copper busbar 31 connected to the connecting end 11 are fixed by bolts, which can make the connection between the wire nose 5 and the copper busbar 31 more firm and safer. The copper busbar 31 extending from the fixed end 2 of the connector 11 is connected to the box body 4 to complete the conductive transmission. A sealing member 23 is provided on the fixed end 21. The tail end of the sealing member 23 is in a closed shape, which plays a role in fixing the connector 1 and protecting the wiring harness. The sealing ring 25 arranged on the fixed end 21 can play a role in waterproofing and dustproofing. A positioning pin 22 is provided on the fixed end 21. The positioning pin 22 is connected to the box body 4 by plugging to complete the positioning assembly.
