Description

Technical Field

[0001] The utility model relates to the technical field of electric wires, in particular to a high-temperature and cold-resistant braided silicone rubber wire. Background Technique

[0002] An electric wire refers to a conductor for transmitting electric energy. It is divided into bare wires, electromagnetic wires, and insulated wires. Bare wires have no insulation layer and include copper and aluminum flat wires, overhead stranded wires, and various profiles (such as shaped wires, bus bars, copper bars, aluminum bars, etc.).

[0003] The silicone rubber braided insulated high-temperature resistant electric wire provided by the publication number "CN209591575U" includes an electric wire. The electric wire includes a conductor, an insulating layer, a high-temperature resistant layer, a fiber braided layer, and a fireproof layer. The outer surface of the conductor is fixedly connected to the inner surface of the insulating layer, the outer surface of the insulating layer is fixedly connected to the inner surface of the high-temperature resistant layer, the outer surface of the high-temperature resistant layer is fixedly connected to the inner surface of the fiber braided layer, the outer surface of the fiber braided layer is fixedly connected to the inner surface of the fireproof layer, and a plurality of support plates are fixedly connected inside the insulating layer. For this silicone rubber braided insulated high-temperature resistant electric wire, the insulating layer and the high-temperature resistant layer are provided inside the electric wire, which can absorb the heat generated by the conductor and disperse the heat. Through the arrangement of the fiber braided layer, it can prevent the fireproof layer and the high-temperature resistant layer from sticking together after long-term use of the electric wire, thereby improving the service life and overall quality of the electric wire.

[0004] However, the following problems still exist in the implementation of the above device:

[0005] In the prior art and the above solution, the insulating layer and the high-temperature resistant layer are provided inside the electric wire, which can absorb the heat generated by the conductor and disperse the heat. However, the cold resistance of the electric wire is ignored. In a low-temperature environment, the hardness of the electric wire and cable will increase. When moving or bending at high speed at low temperature, the electric wire will crack and be damaged, thereby reducing the service life of the electric wire. Content of the Utility Model

[0006] The purpose of the utility model is to provide a high-temperature and cold-resistant braided silicone rubber wire to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] A high-temperature and cold-resistant braided silicone rubber wire includes a wire body. The wire body includes a conductor, an insulating layer, a high-temperature resistant layer, a cold-resistant layer, a fiber braided layer, and a wear-resistant layer. The insulating layer is connected to the outside of the conductor, the high-temperature resistant layer is connected to the outside of the insulating layer, the cold-resistant layer is connected to the outside of the high-temperature resistant layer, the fiber braided layer is connected to the outside of the cold-resistant layer, the wear-resistant layer is connected to the outside of the fiber braided layer, and steel wires are embedded inside the wear-resistant layer.

[0009] By setting a cold-resistant layer, it can play a role in insulating the wire body, effectively blocking the low temperature from the outside world, and avoiding the situation where the hardness of the wire and cable increases in a low-temperature environment, resulting in wire cracking and damage. At the same time, a high-temperature-resistant layer is provided inside the cold-resistant layer, which is made of multiple layers of mica tape and can absorb the heat energy generated by the conductor, preventing the wire from overheating inside and causing damage. At the same time, the fiber braided layer plays a role in tightening the high-temperature-resistant layer, cold-resistant layer, and insulating layer. Considering that the fiber braided layer is prone to wear and will be damaged if not protected, it will not be able to tighten the high-temperature-resistant layer and cold-resistant layer. Therefore, a wear-resistant layer is provided outside the fiber braided layer. The wear-resistant layer is made of nitrile rubber, which can improve the wear resistance of the wire. At the same time, steel wires are provided inside it, which can further improve the wear resistance effect of the wear-resistant layer.

[0010] Preferably, the cold-resistant layer is made of polyurethane foam.

[0011] By setting the cold-resistant layer, due to the good heat insulation performance, waterproof performance, impact resistance, and corrosion resistance of polyurethane foam itself, and its low thermal conductivity, it has good heat insulation performance. Whether it is used indoors or outdoors, it can effectively maintain the temperature and avoid damage to the wire caused by low temperature.

[0012] Preferably, the wear-resistant layer is made of nitrile rubber.

[0013] By setting the wear-resistant layer, the wear-resistant layer is made of nitrile rubber, which is a copolymer formed by the polymerization of acrylonitrile and butadiene monomers. It is mainly produced by the low-temperature emulsion polymerization method, has excellent oil resistance, high wear resistance, and certain heat resistance, and can effectively improve the service life of the wire.

[0014] Preferably, the number of the steel wires is several, and they are distributed in a spiral shape inside the wear-resistant layer.

[0015] By setting the steel wires, the number of the steel wires is several, and they are distributed in a spiral shape inside the wear-resistant layer. When the surface of the wear-resistant layer is worn, the steel wires will be exposed, improving the wear resistance of the wear-resistant layer and preventing the wear-resistant layer from being damaged.

[0016] Preferably, a copper solution coating is connected to the surface of the steel wire.

[0017] By setting the copper solution coating, by attaching the copper solution coating to the surface of the steel wire, the steel wire can be embedded inside the wear-resistant layer.

[0018] Preferably, the high-temperature-resistant layer is made of multiple layers of mica tape.

[0019] By setting the high-temperature-resistant layer, the high-temperature-resistant layer is made of multiple layers of mica tape and can absorb the heat energy generated by the conductor, preventing the heat energy in the conductor from being too high and causing damage, which affects the service life of the wire.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] 1. By providing a cold-resistant layer, the present utility model can play a role in insulating the wire body, effectively blocking the low temperature from the outside world, avoiding the increase in the hardness of the wire and cable in a low-temperature environment, which may cause the wire to crack and be damaged. At the same time, a high-temperature-resistant layer is provided inside the cold-resistant layer, which is made of multiple layers of mica tape and can absorb the heat energy generated by the conductor, avoiding overheating inside the wire and resulting in damage. At the same time, the fiber braided layer plays a role in tightening the high-temperature-resistant layer, cold-resistant layer, and insulating layer. Considering that the fiber braided layer is prone to wear, if not protected, it will be damaged and unable to tighten the high-temperature-resistant layer and cold-resistant layer. Therefore, a wear-resistant layer is provided outside the fiber braided layer. The wear-resistant layer is made of nitrile rubber, which can improve the wear resistance of the wire. At the same time, steel wires are provided inside it, which can further improve the wear resistance effect of the wear-resistant layer.

[0022] 2. By providing steel wires, the number of steel wires is several and they are distributed in a spiral shape inside the wear-resistant layer. When the surface of the wear-resistant layer is worn, the steel wires will leak out, improving the wear resistance of the wear-resistant layer and avoiding damage to the wear-resistant layer.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0031] Example 1:

[0032] A high-temperature and cold-resistant braided silicone rubber wire, including a wire body 1. The wire body 1 includes a conductor 2, an insulating layer 3, a high-temperature-resistant layer 4, a cold-resistant layer 5, a fiber braided layer 6 and a wear-resistant layer 7. The insulating layer 3 is connected to the outside of the conductor 2, the high-temperature-resistant layer 4 is connected to the outside of the insulating layer 3, the cold-resistant layer 5 is connected to the outside of the high-temperature-resistant layer 4, the fiber braided layer 6 is connected to the outside of the cold-resistant layer 5, the wear-resistant layer 7 is connected to the outside of the fiber braided layer 6, and a steel wire 8 is embedded inside the wear-resistant layer 7.

[0033] In this embodiment, considering that the hardness of the wire and cable will increase in a low-temperature environment, and high-speed movement or bending at low temperature will cause the wire to crack and damage, thereby reducing the service life of the wire. Therefore, by setting the cold-resistant layer 5, it can play a role in keeping the wire body 1 warm, effectively blocking the external low temperature, and avoiding the situation where the hardness of the wire and cable increases in a low-temperature environment, resulting in wire cracking and damage. At the same time, the high-temperature-resistant layer 4 is arranged inside the cold-resistant layer 5 and is made of multiple layers of mica tape, which can absorb the heat energy generated by the conductor 2 and avoid overheating inside the wire, resulting in damage. At the same time, the fiber braided layer 6 plays a role in tightening the high-temperature-resistant layer 4, the cold-resistant layer 5 and the insulating layer 3. Considering that the fiber braided layer 6 is prone to wear, if not protected, it will be damaged and unable to tighten the high-temperature-resistant layer 4 and the cold-resistant layer 5. Therefore, a wear-resistant layer 7 is arranged outside the fiber braided layer 6. The wear-resistant layer 7 is made of nitrile rubber, which can improve the wear resistance of the wire. At the same time, a steel wire 8 is arranged inside it, which can further improve the wear resistance effect of the wear-resistant layer 7;

[0034] It solves the problem that the hardness of the wire and cable will increase in a low-temperature environment, and high-speed movement or bending at low temperature will cause the wire to crack and damage, thereby reducing the service life of the wire;

[0035] It should be noted that the way of embedding the steel wire 8 inside the wear-resistant layer 7 is the same as the way of embedding the steel wire 8 in the tire, which is common knowledge for those skilled in the art, so it will not be elaborated here.

[0036] The cold-resistant layer 5 is made of polyurethane foam.

[0037] In this example, by setting the cold-resistant layer 5, it can utilize the characteristics of polyurethane foam itself, which has good heat preservation performance, waterproof performance, impact resistance and corrosion resistance. Due to its low thermal conductivity, it has good heat preservation performance. Whether it is used indoors or outdoors, it can effectively maintain the temperature and avoid damage to the wire caused by low temperature.

[0038] The wear-resistant layer 7 is made of nitrile rubber.

[0039] In this example, by setting the wear-resistant layer 7, the wear-resistant layer 7 is made of nitrile rubber, which is a copolymer formed by the polymerization of acrylonitrile and butadiene monomers. It is mainly produced by the low-temperature emulsion polymerization method, has excellent oil resistance, high wear resistance, and certain heat resistance, and can effectively improve the service life of the wire.

[0040] The number of steel wires 8 is several, and they are spirally distributed inside the wear-resistant layer 7.

[0041] In this example, by setting the steel wires 8, the number of steel wires 8 is several, and they are spirally distributed inside the wear-resistant layer 7. When the surface of the wear-resistant layer 7 is worn, the steel wires 8 will be exposed, improving the wear resistance of the wear-resistant layer 7 and preventing the wear-resistant layer 7 from being damaged.

[0042] A copper solution coating 9 is connected to the surface of the steel wires 8.

[0043] In this example, by setting the copper solution coating 9, by attaching the copper solution coating 9 to the surface of the steel wires 8, the steel wires 8 can be embedded inside the wear-resistant layer 7.

[0044] The high-temperature resistant layer 4 is made of multiple layers of mica tape.

[0045] In this example, by setting the high-temperature resistant layer 4, the high-temperature resistant layer 4 is made of multiple layers of mica tape, which can absorb the heat energy generated by the conductor 2, prevent the heat energy in the conductor 2 from being too high and causing damage, and affect the service life of the wire.

[0046] Working principle: When the wire moves in a low-temperature environment, the cold-resistant layer 5 can play a role in insulating the wire body 1, effectively blocking the external low temperature, preventing the hardness of the wire and cable from increasing in a low-temperature environment and causing the wire to crack and be damaged. At the same time, the high-temperature resistant layer 4 is provided inside the cold-resistant layer 5 and is made of multiple layers of mica tape, which can absorb the heat energy generated by the conductor 2, prevent the wire from overheating inside and being damaged. At the same time, the fiber braided layer 6 plays a role in tightening the high-temperature resistant layer 4, the cold-resistant layer 5, and the insulating layer 3. At the same time, considering that the fiber braided layer 6 is prone to wear, if not protected, it will be damaged and unable to tighten the high-temperature resistant layer 4 and the cold-resistant layer 5. Therefore, a wear-resistant layer 7 is provided outside the fiber braided layer 6. The wear-resistant layer 7 is made of nitrile rubber, which can improve the wear resistance of the wire. At the same time, steel wires 8 are provided inside it, which can further improve the wear resistance effect of the wear-resistant layer 7.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
