[0002] Rubber wire is also called rubber sheath wire, and is a double-insulated wire material. In the wire and cable industry, a shielding layer usually uses chlorinated polyethylene (CPE), and can withstand a temperature of -40 DEG C to 105 DEG C. The performance of the rubber wire determines that the rubber wire can only be used in a low-voltage and low-frequency environment. Rubber wire is also called rubber sheathed flexible cord or rubber power cord. Because of its resistance to high and low temperatures, it is widely used in various fields.

However, the heat generated by the wire during use cannot be transferred in time, which easily leads to a high temperature near the wire and affects the transmission performance of the wire.

[0031] ​With reference to the drawings of the embodiments of the present disclosure, the technical solutions in the embodiments of the present disclosure will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present disclosure. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0032] According to the conception of the present application, embodiments of a high-heat-resistant and wear-resistant rubber wire as an insulating material of an electric wire cable are described herein. Figures 1-2 Specifically, the high-heat-resistant and wear-resistant rubber wire is configured as an integrated structure, which has three components, i.e., an inner sheath 1, a limiting frame 5, and a shielding layer 7. By the cooperation of the structures such as the mounting frame 3, the limiting frame 5, the cavity 4, and the cooling liquid, the heat generated by the wire can be timely transferred, so as to avoid the temperature from affecting the transmission performance of the wire. In addition, by the through hole 11, the cooling liquid in the adjacent cavities 4 can be mutually penetrated, so as to improve the heat transfer effect between the cooling liquids, thereby the heat can be more quickly absorbed.

[0033] In combination with Figures 1-2 The high-heat-resistant and wear-resistant rubber wire provided by the present disclosure includes:

[0034] The inner sheath 1 is internally provided with a supporting frame 2, the supporting frame 2 is fixedly connected with a mounting frame 3 on the side wall, a cavity 4 is formed between the mounting frame 3 and the supporting frame 2, and the cavity 4 is filled with a cooling liquid;

[0035] The limiting frame 5 is fixedly connected to the inner wall of the inner sheath 1, and a first arc-shaped groove 6 is formed in the inner wall of the limiting frame 5;

[0036] The shielding layer 7 is adhered to the outer surface of the inner sheath 1, the outer surface of the shielding layer 7 is adhered with a flame-retardant layer 8, and the outer surface of the flame-retardant layer 8 is adhered with a wear-resistant layer 9.

[0037] According to the technical solution of the present embodiment, the limiting frame 5 and the mounting frame 3 are made of a heat-conducting material, which can be made of heat-conducting silica gel. The present embodiment does not make a specific limitation, and the selection can be made according to the actual situation. The main purpose is to transfer the heat generated by the wire arranged on the limiting frame 5 and the mounting frame 3 to the cooling liquid, and the heat-conducting material does not have the electric conductivity, so as to prevent the current from being broken through.

[0038] According to the technical scheme of the embodiment, the support frame 2 is provided with a circular cavity 10 at the center position, and a through hole 11 is arranged between the circular cavity 10 and the cavity 4. The support frame 2 can not only provide support for the limiting frame 5 and the mounting frame 3, but also can enhance the use strength of the device as a whole and improve the extrusion resistance and tensile resistance. The circular cavity 10 and the through hole 11 can make the cooling liquid in the adjacent cavities 4 penetrate each other, improve the heat transfer effect between the cooling liquids, and thus absorb heat faster, avoiding the influence of high temperature on the transmission performance of the wire.

[0039] According to the technical scheme of the embodiment, the mounting frame 3 is provided with a second arc-shaped groove 12 on the side facing the inner sheath 1, and the second arc-shaped groove 12 corresponds to the first arc-shaped groove 6. The first arc-shaped groove 6 and the second arc-shaped groove 12 are combined to form a circle, which is mainly used for installing and limiting the wire to improve the stability of the wire installation. Since the sidewall of the wire is tightly attached to the mounting frame 3 and the limiting frame 5 after installation, the generated heat can be better transferred outward.

[0040] According to the technical scheme of the embodiment, the shielding layer 7 is made of copper foil or aluminum foil material. It should be noted that the embodiment is not limited here, and can be selected according to actual conditions. The shielding layer 7 can effectively shield the electromagnetic field generated by the current and prevent it from interfering with surrounding elements. In high-voltage wires, the current is large, and a strong magnetic field is generated around it. The shielding layer 7 can limit this electromagnetic field inside the cable to protect surrounding elements from being affected. In addition, when the current leaks, the shielding layer 7 can also guide the leaked current to the grounding net, thereby playing a protective role and avoiding safety hazards.

[0041] According to the technical scheme of the embodiment, the flame-retardant layer 8 is made of polyvinyl chloride or flame-retardant nylon material. It should be noted that the embodiment is not limited here, and can be selected according to actual conditions. The flame-retardant layer 8 can enhance the fire resistance of the wire.

[0042] According to the technical scheme of the embodiment, the wear-resistant layer 9 is made of silicone rubber or polyurethane material. It should be noted that the embodiment is not limited here, and can be selected according to actual conditions. The wear-resistant layer 9 can reduce the friction and wear between the wire and the surrounding environment during long-term use, prolong the service life of the wire, and reduce the failure rate.

[0043] Specifically, in actual use, the wires are installed in the first arc-shaped groove 6 and the second arc-shaped groove 12 to limit the installation of the wires and improve the stability of the wire installation. When the wires generate heat, since the side walls of the wires are tightly attached to the mounting frame 3 and the limiting frame 5 after installation, the generated heat can be better transmitted to the limiting frame 5 and the mounting frame 3, and then the heat will continue to be transmitted to the cooling liquid in the cavity 4. In this way, the heat generated by the wires can be transmitted in time, avoiding the influence of temperature on the transmission performance of the wires. In addition, the through hole 11 can also make the cooling liquid in the adjacent cavities 4 interpenetrate, improve the heat transfer effect between the cooling liquids, and thus absorb heat faster. At the same time, the support frame 2 can not only provide support for the limiting frame 5 and the mounting frame 3, but also enhance the overall use strength of the device, improve its anti-extrusion and anti-stretching ability. The fire-retardant layer 8 can enhance the fire resistance of the wires, and the wear-resistant layer 9 can reduce the friction and wear of the wires with the surrounding environment during long-term use, prolong the service life of the wires, and reduce the failure rate.
