Technical Field

[0001] The utility model relates to the technical field of wire harnesses, in particular to a wear-resistant sealed wire harness. Background Art

[0002] The wiring harness is the overall service equipment for a certain load source group, such as relay lines, switching devices, control systems, etc. In order to facilitate installation and maintenance and ensure that electrical equipment can work under the worst conditions, the wires of different specifications and colors used in the electrical equipment of the whole vehicle are reasonably arranged and integrated into one, and the wires are bundled into bundles with insulating materials, which is both complete and reliable. From the functional point of view, the automotive wiring harness can be divided into two types: power lines that carry power to drive actuators (actuators) and signal lines that transmit sensor input commands.

[0023] Specifically, the wear-resistant sealed wire harness includes a wire harness body 1. The wire harness body 1 is a prior art, which includes a wire core, etc. The wire harness body 1 is installed with a connecting terminal 2 through a connector. When the wire harness needs to be used, it is installed on a predetermined device through the connecting terminal 2 to facilitate the use of the wire harness body 1. A wear-resistant sleeve 3 is sleeved on the wire harness body 1, so that the strength of the wire harness body 1 can be increased by the wear-resistant sleeve 3 during use, the service life of the wire harness body 1 can be improved, and the use effect is better. A clamping mechanism is provided between the connecting terminal 2 and the wear-resistant sleeve 3, which is used to fix the wear-resistant sleeve 3, so that the wire harness body 1 can be fixed, and the wear on the wire harness body 1 can be minimized, and the use effect is better.
