Description

Technical Field

[0001] This application belongs to the technical field of the termination design of wire harnesses and electrical connectors, and particularly relates to a termination structure and method for a wire harness and an electrical connector. Background Art

[0002] A wire harness is a collection of multiple wires. In practical applications, when a wire harness terminates an electrical connector, it means connecting the wire cores at the ends of the wires in the wire harness to the pins of the electrical connector.

[0003] In practice, in order to avoid electromagnetic interference to the wires, it is mostly designed that the wire core of the wire is sequentially coated with an inner insulating layer, a shielding layer, and an outer insulating layer from the inside to the outside, and the shielding layer is grounded to suppress electromagnetic interference.

[0004] Currently, when a wire harness terminates an electrical connector, the wire cores at the ends of the wires need to be exposed, that is, a part of the inner insulating layer, the shielding layer, and the outer insulating layer at the ends of the wires need to be cut off. As a result, the shielding layer cannot completely cover the outside of the wire core, and when terminating the electrical connector, there are easily holes and gaps, resulting in a weakened ability to suppress electromagnetic interference, or it is not easy to disassemble and assemble again after terminating the electrical connector, and the maintenance cost is relatively high.

[0005] In view of the existence of the above technical defects, this application is proposed.

[0006] It should be noted that the disclosure of the above background art content is only used to assist in understanding the inventive concept and technical solution of the present invention, and it does not necessarily belong to the prior art of this patent application.
