[0001] The invention relates to the technical field of wire harness assemblies, and in particular to an automobile high-voltage wire harness assembly. Background Art

[0002] The automotive high-voltage wiring harness assembly is a vital component in electric vehicles. It is responsible for transmitting high-voltage electrical energy and connecting core components such as batteries, motors and electronic controls. The layout of the high-voltage wiring harness assembly has been carefully planned to adapt to the complex structure of the vehicle and withstand vibration and temperature changes during driving. Its reliable performance is indispensable to ensure the power transmission and safe operation of the vehicle, and is one of the key factors for the efficient and stable driving of electric vehicles. The automotive high-voltage wiring harness assembly usually includes high-voltage cables, connectors, terminals, protective sleeves, seals, fixing brackets and shielding layers; these components together constitute the automotive high-voltage wiring harness assembly to ensure the safe and stable transmission of high-voltage electricity in the automotive system; The automobile high-voltage wiring harness assembly is fixed to the automobile through a fixing bracket, so that the wiring harness will not shake or vibrate with the automobile while the automobile is driving; however, the wiring harness part between the two fixing brackets on the automobile high-voltage wiring harness assembly is not fixed, so it will shake or vibrate, which causes limitations.

[0003] To this end, we propose an automotive high-voltage wiring harness assembly. Summary of the invention

[0009] By arranging a fixing rod and a fixing cylinder between two fixing brackets, the fixing cylinder and the fixing rod are relatively fixed to support the connecting sleeve, so that the connecting sleeve fixes the cable. In this way, the cable part between the fixing brackets will not shake during the driving of the car, thereby preventing the cable from being worn or fatigued and broken.
