Description

Technical Field

[0001] This utility model relates to the field of high-voltage wire harness technology, and in particular to a high-voltage wire harness fixing bracket. Background Technology

[0002] High-voltage wiring harnesses are key connection components in high-voltage systems such as new energy vehicles and energy storage equipment. They are mainly composed of high-voltage wires, insulation layers, shielding layers, connectors, and protective sleeves. Their core function is to transmit high voltage and high current within high-voltage systems, such as connecting key components of new energy vehicles, such as power batteries, motor controllers, and charging interfaces, to achieve efficient power transmission.

[0003] To ensure safe use, the insulation layer of high-voltage wiring harnesses must have excellent high-voltage and high-temperature resistance, the shielding layer can reduce electromagnetic interference, and the protective sleeve can resist vibration, friction and corrosion in the external environment. The whole system must meet strict electrical performance and mechanical strength requirements to ensure the stable and safe operation of the high-voltage system. In order to increase the stability of high-voltage wiring harnesses after installation, high-voltage wiring harness fixing brackets are needed for fixing. These brackets can fix the high-voltage wiring harnesses in specific positions on the vehicle body or equipment to prevent the wiring harnesses from being damaged by vibration, movement and friction with other components.

[0004] High-voltage wiring harnesses are subjected to continuous vibrations and impacts from the engine and road bumps during vehicle operation. Traditional rigid brackets can easily cause hard friction between the wiring harness and the bracket, resulting in wear on the outer sheath or even breakage of the internal wires. At the same time, the vibration direction varies under different operating conditions, such as longitudinal, lateral, and vertical. A single-direction buffer structure cannot fully offset the vibration energy, and long-term use will reduce the service life and safety of the wiring harness.
