[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which can be defined as: a collection of the following parts; one or more insulated cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors. Wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables.

[0003] The existing cables have poor compression resistance and will be damaged if they are crushed for a long time during use, thus shortening their service life.

[0004] Therefore, it is necessary to provide a vehicle-mounted cable with a compression resistance function to solve the above problems. Utility Model Content

[0005] Based on the above problems existing in the prior art, the purpose of the embodiments of the present application is to provide a vehicle-mounted cable with a compression resistance function.

[0006] The technical solution adopted by the present application to solve its technical problems is: a vehicle-mounted cable with pressure-resistant function, including a wire sleeve and a connecting sleeve, the inner surface of the wire sleeve is fixedly installed with an insulating layer, the inner side of the insulating layer is fixedly installed with an outer skin, the surface of the outer skin is provided with a fire-retardant coating, the inside of the outer skin is provided with a wire core, the front end of the connecting sleeve is provided with a supporting layer, and the rear end of the connecting sleeve is fixedly connected with a plug connector.

[0007] Furthermore, a telescopic protective sleeve is fixedly installed on the inner side of the connecting sleeve, and the telescopic protective sleeve covers the upper surface of the supporting layer.

[0008] Furthermore, a telescopic support rod is fixedly mounted on the lower end of the telescopic protective cover, and the telescopic support rod is in contact with the supporting layer.

[0009] Furthermore, a resin layer is filled around the wire core.

[0010] The beneficial effect of the utility model is that the telescopic protective sleeve is pulled out from the connecting sleeve and covers the supporting layer. At this time, the telescopic support rod at the lower end of the telescopic protective sleeve will also be telescoped to support the surface of the supporting layer, thereby being able to protect the cable in multiple directions and enhancing the pressure resistance.

[0016] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0017] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0018] In the present invention, unless otherwise specified, directions such as "up" and "down" are usually relative to the directions shown in the drawings, or relative to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are usually relative to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.
