The self-riveting stud 202 is insulated from the fuse box 3 and the output terminal 4, and the output terminal 4 is insulated from the hexagonal nut 6, ensuring that the current flows from the copper busbar body 2 through the fuse body 302 to the output end and is normally conducted, and the fuse body 302 can play an overcurrent protection role.

[0029] In the case implementation, an insulating sleeve is fixedly connected around the embedded bolt 102, and a through hole compatible with the embedded bolt 102 is opened on the busbar body 201. The aperture of the through hole is larger than the diameter of the embedded bolt 102. A certain gap is set between the seat body 101 and the embedded bolt 102 to form insulation.
