The conventional rubber wire harness sheath generally has a circular hole in the middle of the sheath to pass the wire harness, and then a sleeve or a tail is designed on one side or both sides of the through hole to facilitate binding the wire harness and the rubber sheath with tape. , using the two does not produce relative movement. However, when the vehicle is at a non-uniform speed or the angle at which the harness emerges from the sheath hole is large, the two will have a certain impact force, thereby increasing the fatigue strength of the rubber sheath, resulting in a decrease in the life, the sealing property is lowered, and the harness is detached from the line. Holes, which in turn affect the performance of the car.

The rubber body provided with the through hole of the new wire harness sheath is not in contact with the sheath, and the sheath is provided with a groove, and the front and rear sides of the rubber member body are provided with a sleeve for fixing the wire harness at the edge of the through hole, and then the rubber body body is the outer side of one side of the sleeve is provided with a horn-shaped sleeve, and the front edge of the sleeve is integrally connected with the front end of the sheath through a pleated connecting sleeve. Due to the wrinkles on the connecting sleeve, it can be bent and telescoped, which can cushion the impact force of the two to improve the service life of the rubber sheath and ensure the sealing of the rubber sheath.
