The first fastening screw 4 has the advantages of being capable of being frequently disassembled without the problem of assembly endurance failure, and the first fastening screw 4 can provide enough pressure to conduct the first connection portion 12 with the circuit on the first circuit board 100.
However, since the strength of the first circuit board 100 is low, if the first connection portion 12 is directly fixed to the first circuit board 100 by the first fastening screw 4, an operator can easily grasp a force when tightening the first fastening screw 4, which may damage the first circuit board 100.

As shown in fig. 2, the two clamping pieces 2111 are arc-shaped, and the two arc-shaped clamping pieces 2111 can match the arc of the inner insulating sheath 32 and clamp the inner insulating sheath 32.
Preferably, the second fixing member 2 is an elastic sheet, and the conduction portion 21 and the second connection portion 22 can be bent mutually to adjust the size of an included angle between the conduction portion 21 and the second connection portion 22. The link structure does not need welding, and has no limitation on application structure space and materials. When an included angle exists between the first circuit board 100 and the second circuit board 101, an operator can realize connection at any position by adjusting the bending degree of the wire harness and the second fixing member 2.
