[0033] As shown in Figure 1 , the insulating body includes an insulating protective layer 2 of the electric core wire 201 and an insulating shell 1 of the connecting head, and both ends of the insulating protective layer 2 are seamlessly connected with the insulating shell 1.

[0034] As shown in Figure 1 , the connecting head includes a first connecting head and a second connecting head, and one side of the first connecting head and the second connecting head both adopts a plane structure design to ensure the connection stability, in the embodiment, the side of the first connecting head and the second connecting head which is attached to the circuit board is designed as a plane structure, so that the connection line is more stable after connection, and the problem of loose and loose welding is reduced.

[0035] As shown in Figure 1 , the insulating body located between the first connecting head and the second connecting head is provided with anti-skid lines 5, in the embodiment, the first connecting head is used for plug-in connection, and the second connecting head is used for fixing on the circuit board connection and generally does not need to be disassembled, therefore, the insulating shell 1 of the first connecting head is provided with parallel strip-shaped anti-skid lines 5, and the second connecting head is not provided with anti-skid lines 5, in other schemes, the insulating shell 1 of the second connecting head is provided with anti-skid lines 5.

The outer insulating body provides structural support and electrical insulation. A double-layer shielding layer is provided between the insulating body and the core wires to suppress high-frequency and low-frequency interference.
