Embodiment Construction

[0020] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0021] The embodiment of rubber sheath for automobile wiring harness of the present invention: as figure 1 and figure 2 As shown, the rubber sheath includes a central sheath 1 for the wiring harness 8 to pass through and a protective ring 2 connected to the sheet metal hole 9. Both the protective ring 2 and the central sheath 1 are made of rubber, and the protective ring The strength of 2 is not higher than that of the central sheath 1; the protective ring 2 is cap-shaped with a closed front end and an open rear end, and the rear section of the protective ring 2 and the outer wall of the central sheath 1 form an annular cavity. The outer wall of the rear section of the sleeve 1 is protruded with an ...

Abstract

The invention relates to a rubber sheath for an automobile wire harness. A ring-shaped convex shoulder which is plugged into a ring-shaped cavity is arranged on the outer wall of the rear section of a central sheath in a convex mode; a ring-shaped permanent magnet which is coaxial with the central sheath is pre-embedded and fixedly arranged in the ring-shaped convex shoulder; a ring-shaped blocking slot is formed in the outer peripheral surface of a protective ring-shaped sleeve; a U-shaped ring-shaped cavity which fits to and is nested with the ring-shaped blocking slot, and a winding coil which is coaxially fixed on a position, close to the central side, of the U-shaped ring cavity, is pre-arranged in the protective ring-shaped sleeve; charged electrorheological fluid and an electrode inserted into the electrorheological fluid are arranged in the U-shaped ring-shaped cavity; and the electrode is electrically connected with the winding coil through a guide wire which is pre-arranged in the protective ring-shaped sleeve. After the wire harness is pulled, the central protective sleeve moves forwards relative to the protective ring-shaped sleeve, so that the permanent magnet coaxially relatively moves in the winding coil; and when the winding coil is electrified, the electrorheological fluid in the ring-shaped cavity is electrified, so that rigidity is improved, and therefore, the protective ring-shaped sleeve is prevented from dropping from a sheet metal hole.

Description

technical field [0001] The invention belongs to the field of rubber sheaths, in particular to a rubber sheath for automobile 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 s...
