[0002] Wheel speed sensor is a sensor used to measure the rotation speed of the car wheels. For modern cars, wheel speed information is essential. Vehicle dynamic control system (VDC), electronic stability program (ESP), anti-lock braking system (ABS), automatic transmission control system, etc. all need wheel speed information. Therefore, wheel speed sensor is one of the most critical sensors in modern cars.

[0003] The existing wheel speed sensor wiring harness is usually directly exposed to the outside, or is only wrapped with a bellows. When in use, the bellows is easy to bend, and the bending range is large, which leads to the phenomenon of the wheel speed sensor wiring harness breaking. In addition, the existing wheel speed sensor wiring harness protective shell has poor connectivity between its end and the wheel speed sensor housing, and debris is easy to enter the gap, which increases the wear between the wiring harness and the protective shell. Therefore, the existing wheel speed sensor wiring harness protective shell has the disadvantages of poor protection performance for the wiring harness and poor sealing between the protective shell and the wheel speed sensor housing.
