Technical Field

[0001] The utility model relates to the technical field of automobile wiring harnesses, in particular to an automobile communication wiring harness component. Background Art

[0002] The automotive wiring harness is the main network of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to the contact terminal made of copper material, which is crimped with the wire and cable, and then the insulator is plastic-pressed on the outside or a metal shell is added. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing and downstream application industries. The wiring harness is widely used and can be used in automobiles, household appliances, computers and communication equipment, various electronic instruments and meters, etc. The body wiring harness connects the entire body. The automotive communication wiring harness is an indispensable part of the car.

[0003] Authorization announcement number CN217115484U discloses an electric vehicle communication harness. The patented technology sets a first pushing mechanism, etc. When the harness body needs to be fixed, the clamping foot is fixed in the body sheet metal hole on the car, or in other existing fixing holes in the car. Then, the harness body is placed between the clamp and the lower arc plate, and the upper arc plate and the lower arc plate are fixed by the mounting mechanism. At this time, the first spring is compressed, thereby fixing and clamping the harness body. However, there are disadvantages in the use of arc plates and spring mechanisms when fixing the harness in this scheme. When the arc plates and springs are loosened due to unexpected reasons, the open arc plates and springs are very likely to fly out of the clamp from the opening under the action of centrifugal force, which poses a safety hazard. In addition, the material of the fixing device is too poor, and it is not moisture-proof, explosion-proof, or anti-interference. The integrated circuit box is easily deformed, which can easily affect the damage of components inside the integrated circuit, thereby reducing the practicality of the automotive communication harness assembly when in use. Therefore, an automotive communication harness assembly is needed to improve the above problems. Utility Model Content
