Description

Technical Field

[0001] The utility model relates to the technical field of electric wires, in particular to a wear-resistant electric wire. Background Art

[0002] Products with a small number of cores, small product diameter and simple structure are usually called wires. Those without insulation are called bare wires, and the others are called cables. Conductor cross-sectional areas that are larger (greater than 6 square millimeters) are called large wires, and those that are smaller (less than or equal to 6 square millimeters) are called small wires. Insulated wires are also called cloth wires.

[0003] At present, the wires used outdoors are mainly composed of a wire core, an insulating layer installed on the outside of the wire core, a shielding layer installed on the outside of the insulating layer, and an outer sheath installed on the outside of the shielding layer. Although the wires of this structure can have good wear resistance under the action of the outer sheath when in use, the wires of this structure are directly exposed to the external environment when in use, which leads to the wires being easily affected by the external environment and aging quickly during use. At the same time, since the wires of the above structure mainly rely on the heat transfer between layers to realize the outward dissipation of the internal heat of the wires when in use, the heat transfer speed between layers is slow, which makes the internal heat of the wires untimely dissipated, thereby causing the wires to overheat and burn, resulting in a relatively low service life of the wires. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] The technical problem to be solved by the utility model is to provide a wear-resistant electric wire with anti-aging protection function and rapid heat dissipation function in view of the current status of the prior art.

[0006] (II) Technical solution

[0007] The utility model is achieved through the following technical scheme: the utility model proposes a wear-resistant electric wire, including an outer sheath, a flexible protective tube is installed outside the outer sheath, grooves are opened on the outer wall of the flexible protective tube at equal intervals, thermal conductive rubber strips are installed at equal intervals at the bottom of the grooves, a wear-resistant strip is installed outside the flexible protective tube between two of the grooves, and the inner side of the outer sheath is the main structure of the electric wire.

[0008] Furthermore, the main structure of the electric wire includes a flame retardant layer closely connected to the inner wall of the outer sheath, a shielding layer installed on the inner side of the flame retardant layer, an insulating layer installed on the inner side of the shielding layer, and a conductive core installed on the inner side of the insulating layer.

[0009] By adopting the above technical solution, the conductive wire core is the main structure for realizing the conduction of the wire, and the insulating layer can provide insulation protection for the conductive wire core.

[0010] Furthermore, the flexible protective tube is a PVC insulating pipe, and the flexible protective tube is bonded to the outer sheath.

[0011] By adopting the above technical solution, it can be ensured that the flexible protective tube has good corrosion resistance and high temperature resistance, so as to reduce the damage of the external environment to the main structure of the wire and delay the aging speed of the main structure of the wire.

[0012] Furthermore, the wear-resistant strip is a TPU wear-resistant rubber strip, and the wear-resistant strip is bonded to the flexible protective tube.

[0013] By adopting the above technical solution, the wear-resistant strip can effectively improve the wear resistance and UV resistance of the main structure of the wire.

[0014] Furthermore, the thermally conductive adhesive strip is a thermally conductive silicone strip, and the thermally conductive adhesive strip passes through the flexible protective tube, the outer sheath, the flame retardant layer, and contacts the shielding layer.

[0015] By adopting the above technical solution, the thermally conductive adhesive strip can quickly conduct heat out of the main structure of the wire, ensuring efficient heat dissipation of the wire when in use.

[0016] Furthermore, the cross section of the groove is a V-shaped structure, and the groove is formed on the flexible protective tube.

[0017] By adopting the above technical solution, the groove can make the heat dissipation area outside the thermally conductive adhesive strip larger, which is convenient for the heat dissipation of the thermally conductive adhesive strip.

[0018] Furthermore, the flame retardant layer is bonded to the outer sheath and the shielding layer, and the insulating layer is bonded to the conductive core and the shielding layer.

[0019] By adopting the above technical solution, it can be ensured that the flame retardant layer and the insulating layer are reliably installed and fixed in the electric wire.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] In order to solve the problem that the current outdoor wires are mainly composed of a wire core, an insulating layer installed on the outside of the wire core, a shielding layer installed on the outside of the insulating layer and an outer sheath installed on the outside of the shielding layer, although the wires of this structure can have good wear resistance under the action of the outer sheath when in use, the wires of this structure are directly exposed to the external environment when in use, which leads to the wires being easily affected by the external environment and rapidly aging during use. At the same time, since the wires of the above structure mainly rely on the heat transfer effect between layers to achieve the outward dissipation of the internal heat of the wires when in use, it is easy to cause the internal heat of the wires to be dissipated untimely due to the slow transfer speed of heat between layers, thereby causing the wires to overheat and burn, resulting in a relatively low service life of the wires. On the one hand, the utility model can isolate the main structure of the wire from the external environment under the action of a flexible protective tube, preventing the main structure of the wire from being rapidly aged due to the influence of the external environment when in use, and on the other hand, cooperate with a thermal conductive adhesive strip to achieve the rapid outward dissipation of heat in the main structure of the wire, so that the internal heat dissipation efficiency of the wire is higher when in use, preventing the wires from being overheated and burned, and improving the service life of the wires.

The inner side of the outer sheath 7 is the main structure of the wire, and the flexible protective tube 8 is a PVC insulating pipe, which can ensure that the flexible protective tube 8 has good corrosion resistance and high temperature resistance to reduce the damage of the external environment to the main structure of the wire and delay the aging speed of the main structure of the wire.

The conductive core 2 is the main structure for realizing the conduction of the wire, and the insulating layer 4 can provide insulation protection for the conductive core 2.

The groove 9 can make the heat dissipation area on the outside of the thermally conductive strip 3 larger, which is convenient for the heat dissipation of the thermally conductive strip 3.

At the same time, the thermal conductive strip 3 is used to realize the rapid dissipation of heat in the main structure of the wire to the outside, so that the internal heat dissipation efficiency of the wire is higher when in use, preventing the wire from overheating and burning, and improving the service life of the wire.
