Embodiment 1

[0016] Embodiment one: if Figure 1-2 As shown, in this embodiment, the rubber sheath used for the automobile wiring harness includes a rubber body 1 provided with a through hole and a sheath 2 located outside the rubber body 1, the rubber body 1 and the sheath 2 are not Contact, the sheath 2 is provided with a groove 3 for card sheet metal, the front and rear sides of the rubber part body 1 and the edge of the through hole are provided with a sleeve 4 for fixing the wire harness, on the side of the rubber part body 1 The outer side of the sleeve is provided with a bell-shaped sleeve 5, the front edge of the bell-shaped sleeve 5 is connected to the front end of the sheath 2 through a connecting sleeve 6, and the connecting sleeve 6 is provided with folds 7 .

[0017] The cross section of the sheath 2 is a hollow concave structure inside.

[0018] The folds 7 are protrusions along the circumference of the connecting sleeve 6 .

[0019] The edge profile of the sheath 2 is a c...

Embodiment 2

[0020] Embodiment two: if Figure 3-4 As shown, this embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: the outer side of the sleeve 4 on the other side of the rubber body 1 is provided with a bell-shaped wire harness to limit the movement. Sleeve 8, the wire harness movement limiting sleeve 8 is located at the rear side of the sheath 2 .

[0021] The specific installation methods of rubber sheaths for automotive wiring harnesses include:

[0022] Step 1: Pass the wire harness through the through hole of the rubber part body 1, and wrap the wire harness and the sleeve 4 with adhesive tape at both ends;

[0023] Step 2: Use the groove 3 on the sheath 2 to clamp the edge of the sheet metal hole on the body sheet metal and fix it, and the assembly is completed.

[0024] When the vehicle is bumping, the force generated by the swing of the wire harness is partially buffered by the folds 7 on the connecting sleeve 6...

Abstract

The invention discloses a rubber sheath for an automobile wire harness. The rubber sheath comprises a rubber part body provided with a through hole and a sheath body located outside the rubber part body, the rubber part body does not make contact with the sheath body, a groove for clamping a metal plate is formed in the sheath body, and sleeves used for fixing the wire harness are arranged at the positions, located on the edge of the through hole, of the front side and the rear side of the rubber part body; a horn-shaped sleeve is arranged at the outer side of the sleeve on one side of the rubber part body, the front edge of the horn-shaped sleeve and the front end of the sheath body are connected into a whole through a connecting sleeve, and wrinkles are arranged on the connecting sleeve. Impact between the wire harness and a bodywork metal plate hole can be buffered through the sheath, the wire harness can be prevented from moving excessively, the fatigue strength of the rubber sheath is reduced, and the service life of the rubber sheath is prolonged.

Description

technical field [0001] The invention relates to a rubber sheath, in particular to a rubber sheath used for automotive wire harnesses. Background technique [0002] At present, the general structure of the rubber sheath for the automobile wire harness to pass through the sheet metal hole is: a round hole is opened in the middle of the rubber sheath to allow the wire harness to pass through, and a section of sleeve or tail is designed on one or both sides of the through hole of the rubber sheath to facilitate the use of adhesive tape. Bind the wire harness and the rubber sheath so that the rubber sheath and the wire harness do not move relative to each other. However, in actual use of this kind of rubber sheath, especially when the vehicle is in a state of non-uniform speed (such as when the car is running on a bumpy road or a sudden brake), or when the angle of the wire harness coming out of the sheath hole is very large, due to the sheath The sleeve is fixed on the sheet me...
