Description

Terminal sleeve for wire harness

Technical Field

The application relates to the technical field of wire harness terminal protection devices, in particular to a terminal sleeve for a wire harness.

Background

The wire harness is a component which is formed by pressing a connector (connector) punched by a copper material and an electric wire and cable, then molding and pressing an insulator outside the connector or adding a metal shell outside the connector, and bundling the connector with the wire harness to form a connecting circuit. The connection between the wires and the connectors in the wire harness is fragile, and the wires are easy to be damaged to cause short circuit and the like, which affects the normal work of the wire harness. Therefore, a protective sleeve is arranged at the connection position of the terminal and the wire in a sleeved mode in the prior art, and therefore the wire harness assembly has the advantages that the phenomenon that the outer skin of the wire is scalded when a circuit is not communicated and crimping is carried out due to the fact that the connector and the wire are separated in the wire harness assembly is avoided.
