Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness protection technology, specifically a waterproof and dustproof protection device for wheel speed sensor wiring harnesses. Background Technology

[0002] Wheel speed sensors are used to measure the rotational speed of car wheels. For modern cars, wheel speed information is essential. Vehicle dynamic control systems, electronic stability programs, anti-lock braking systems, and automatic transmission control systems all require wheel speed information. Therefore, wheel speed sensors are one of the most critical sensors in modern cars. Generally speaking, all speed sensors can be used as wheel speed sensors. However, considering practical factors such as the working environment of the wheels and the size of the space, the commonly used wheel speed sensors are mainly: magnetoelectric wheel speed sensors and Hall effect wheel speed sensors. Existing wheel speed sensors are directly exposed to the outside. Due to the lack of a protective structure, dust easily accumulates on the surface of the wiring harness after long-term use, and rainwater can easily enter the wiring harness. Some wiring harnesses are wrapped with waterproof tape, making it inconvenient to disassemble them later. Utility Model Content

[0003] The purpose of this utility model is to provide a waterproof and dustproof protection device for wheel speed sensor wiring harnesses, so as to solve the problems mentioned in the background art. Existing wheel speed sensors are directly exposed to the outside. Due to the lack of a protective structure, dust easily adheres to the surface of the wiring harness after long-term use, and rainwater easily enters the wiring harness. Some wiring harnesses are wrapped with waterproof tape, making it inconvenient to disassemble them later.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a waterproof and dustproof protection device for wheel speed sensor wiring harness, comprising a mounting shell, a waterproof component, and a connecting component;
