Description

Vehicle cable with high abrasion resistance

Technical Field

The utility model relates to a vehicle cable field especially relates to a vehicle cable with high abrasion resistance.

Background

With the popularization of automobiles, in order to ensure the normal transmission of automobile power, the automobile cable technology is also continuously updated. The wire diameter and the heat insulation performance of the vehicle cable are higher than those of a common cable, and meanwhile, in order to ensure that the vehicle cable is not easy to break, most of the vehicle cables adopt copper multi-core flexible wires, so that the requirement on the wear resistance of the vehicle cable is improved, and meanwhile, the vehicle cable is larger in wire diameter and is cracked in the using process.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model aims at providing a low in manufacturing cost, wear resistance is good, the automobile-used cable of difficult fracture, and above-mentioned technical purpose is realized through following technical scheme:

the utility model provides an automobile-used cable with high abrasion resistance which characterized in that: the rubber cable comprises an outer sheath, an elastic layer, an inner sheath, an insulating layer and a plurality of wire cores which are sequentially wrapped from outside to inside, wherein a supporting tube with a triangular cross section is arranged between every two adjacent wire cores, the outer sheath is provided with a plurality of rubber bumps, and the rubber bumps are uniformly distributed on the outer side surface of the outer sheath; tensile strand silk is uniformly distributed in the inner cavity of the inner sheath.

Further: buffer layers are filled between the insulating layer and the wire cores and between the insulating layer and the supporting tubes.

Preferably: the rubber salient points are in a spherical crown shape.

Preferably: the thickness of the outer sheath is 1.5 mm-2.5 mm, the thickness of the elastic layer is 0.5 mm-1.2 mm, the thickness of the inner sheath is 0.8 mm-1.5 mm, and the thickness of the insulating layer is 0.6 mm-1.8 mm.

The utility model has the advantages that: the rubber bumps are arranged on the outer side surface of the outer sheath, so that the contact area between the outer sheath and the outside is reduced, the wear resistance is improved, and the service life of the vehicle cable is prolonged; because the salient points are made of rubber materials, the cable can play a certain buffering role when being bent, and is not easy to crack; the supporting tube is arranged between the adjacent wire cores, so that the positions of the wire cores are relatively stable, the strength of the cable is improved, and the wire cores are protected; by arranging the double-layer sheath and arranging the elastic layer between the outer sheath and the inner sheath, when the vehicle cable is extruded from the outside, the elastic layer contracts, so that the outer sheath and the inner sheath are better protected, and the service life is prolonged; tensile strand silk is arranged in the inner cavity of the inner sheath, so that the tensile capacity of the vehicle cable is enhanced.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1, the vehicle cable with high abrasion resistance comprises an outer sheath 1, an elastic layer 2, an inner sheath 3, an insulating layer 4 and a plurality of wire cores 5 which are sequentially wrapped from outside to inside, a supporting pipe 7 with a triangular cross section is arranged between every two adjacent wire cores 5, the insulating layer 4, the wire cores 5 and the supporting pipe 7 are filled with a buffer layer 6, the outer sheath 1 is provided with a plurality of rubber bumps 11, the rubber bumps 11 are preferably in a spherical crown shape, and the vehicle cable is uniform in stress and good in abrasion resistance. The rubber bumps 11 are uniformly distributed on the outer side surface of the outer sheath 1. Tensile strand wires 31 are uniformly distributed in the inner cavity of the inner sheath 3, so that the tensile property is ensured.

The utility model discloses when using, at first because rubber bump 11 has reduced the area of contact of oversheath with the outside, has played the guard action to oversheath 1, and because rubber bump 11 has certain tensile ability, when the automobile-used cable is buckled or is born external pressure, be difficult for taking place the fracture. And set up the double-deck protection of oversheath 1 and inner sheath 3, set up elastic layer 2 simultaneously between oversheath 1 and inner sheath 3, when the oversheath 1 received the extrusion force, elastic layer 2 took place to shrink, protected oversheath 1 to a certain extent, guaranteed the security of inner sheath 3 simultaneously, prolonged the life of cable. And buffer layer 6 also has certain elastic action, and cooperation elastic layer 2, double cushioning effect has protected inside sinle silk 5 better.

Combine experimental data and manufacturing cost to synthesize and consider, the utility model discloses well each layer thickness is: the thickness of the outer sheath 1 is 1.5 mm-2.5 mm, the thickness of the elastic layer 2 is 0.5 mm-1.2 mm, the thickness of the inner sheath 3 is 0.8 mm-1.5 mm, and the thickness of the insulating layer 4 is 0.6 mm-1.8 mm.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
