Description

Technical Field

[0002] As an important carrier for transmitting electric energy in the high-voltage system of electric vehicles, high-voltage wire harnesses have the characteristics of thick wire diameter and high carrying voltage. As an important part of the design of the wiring harness layout, the fixing method of the high-voltage wire harness should follow the principles of easy installation, easy maintenance, safety and stability.

[0003] Figure 1 , Figure 2 The following are the structures and installation methods of the existing high-voltage harness fixing clamps. When installing, first push the high-voltage harness 400 into the groove of the clamp 100, and then use the fastening bolts 200 to fix the clamp 100 to the bracket 300, so as to achieve the purpose of fixing the harness. Since both the high-voltage harness 400 and the clamp 100 are in an active state before the bolts are tightened, it is difficult for the assembler to control both at the same time, which increases the difficulty of installation; when the installation of the harness passing through the same clamp involves multiple assembly stations, since the clamp is not fixed in advance, the clamp needs to be repeatedly disassembled and assembled during the transfer process, which is time-consuming and laborious; after fixing the harness with the existing clamp, if the harness needs to be removed for maintenance later, the clamp needs to be removed first, which affects work efficiency. Summary of the invention

[0004] In order to solve the problems existing in the existing fixed wire clamps, the utility model provides a high-voltage wire harness fixed wire clamp assembly which is easy to install and disassemble.
