[0002] At present, wires and cables are mainly 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 insulating cores, and their respective coatings, total protective layers and outer sheaths.

Therefore, the surface temperature of wires and cables will continue to rise. As the surface temperature of wires and cables continues to rise, it will eventually affect the signal transmission of wires and cables, and even cause fires. Utility Model Content

[0023] The present application is further described in detail below in conjunction with the accompanying drawings.

[0024] The present application embodiment discloses a high temperature resistant wire and cable, referring to Figure 1 , Figure 2 , including a main line body 1, and a plurality of conductive cores 2 arranged inside the main line body 1. A protective cover 3 is detachably mounted on the outside of the main line body 1, and the protective cover 3 is made of elastic rubber material. Multiple groups of hanging ears 30 are fixedly arranged on the outer wall of the protective cover 3, and adjacent groups of hanging ears 30 are arranged on the outer wall of the protective cover 3 at circumferential intervals, and the hanging ears 30 in the same group are arranged in sequence along the length direction of the main line body 1.

[0025] like Figure 1 , Figure 3 As shown, a through hole 31 is formed between the hanging ear 30 and the outer wall of the protective sleeve 3, and the outer wall of the protective sleeve 3 is penetrated by the same water pipe 4 through each through hole 31. The water pipe 4 is sequentially penetrated through the corresponding through holes 31, and the water pipe 4 is spirally wound on the outer wall of the protective sleeve 3. The water inlet and the water outlet of the water pipe 4 are respectively located at the two ends of the main line body 1.

[0026] like Figure 1 , Figure 3 As shown, a suction cup 35 is fixedly installed on the outer wall of the hanging ear 30 away from the main line body 1, and the suction cup 35 is also made of rubber material. By adsorbing the suction cup 35 on the ground or the wall of a building, the main line body 1 can be hung and fixed on the wall under the action of the suction cup 35, thereby facilitating the hanging and fixing of the main line body 1.

[0027] like Figure 1 , Figure 3As shown, a male Velcro 32 is fixedly provided at one end of the protective sleeve 3, and the length of the male Velcro 32 extends along the length direction of the protective sleeve 3, and a female Velcro 33 for bonding and fixing with the male Velcro 32 is fixedly provided at the other end of the protective sleeve 3. The length of the female Velcro 33 also extends along the length direction of the protective sleeve 3, and the width of the female Velcro 33 is greater than the width of the male Velcro 32. The protective sleeve 3 is wrapped around the outside of the main line body 1 by bonding the male Velcro 32 and the female Velcro 33.

[0028] When the protective sleeve 3 needs to be installed on the outer wall of the main line body 1, the protective sleeve 3 is first wrapped around the outside of the main line body 1, and then the male Velcro 32 and the female Velcro 33 located at the two ends of the protective sleeve 3 are bonded and fixed to each other, and the protective sleeve 3 can be fixedly installed on the outer wall of the main line body 1. When the protective sleeve 3 needs to be removed from the main line body 1, it is only necessary to separate the male Velcro 32 and the female Velcro 33 from each other, so that the protective sleeve 3 can be smoothly removed from the main line body 1, and the entire installation and removal process is very convenient and quick. In addition, the male Velcro 32 and the female Velcro 33 can make the protective sleeve 3 adapt to the installation of main lines 1 with different diameters.

[0029] like Figure 1 , Figure 3 As shown, a plurality of limit strips 5 are fixedly arranged on the outer wall of the protective sleeve 3, and the limit strips 5 are respectively located between adjacent hanging ears 30, and the limit strips 5 are located on the winding path of the water pipe 4. One end of the limit strip 5 is connected and fixed to the outer wall of the protective sleeve 3, and the other end of the limit strip 5 is fixedly installed with a male buckle 50, and the outer wall of the protective sleeve 3 is fixedly installed with a female buckle 34 for interlocking and fixing with the respective male buckles 50. When the water pipe 4 is wound around the outside of the protective sleeve 3, the limit strip 5 is used to further limit the water pipe 4 and press it against the outer wall of the protective sleeve 3, so as to ensure that the water pipe 4 and the outer wall of the protective sleeve 3 fit each other, and further ensure that the coolant passed into the water pipe 4 can smoothly take away the excess heat on the surface of the main line body 1, thereby ensuring the cooling effect of the water pipe 4.

[0030] like Figure 1 , Figure 3 As shown, at least two limiting pieces 10 are fixedly arranged on the outer wall of the main line body 1, the limiting pieces 10 are coaxially arranged with the main line body 1, and the limiting pieces 10 are symmetrically arranged at both ends of the main line body 1. The limiting pieces 10 are used to contact the outer wall of the end of the protective sleeve 3, and the protective sleeve 3 is wrapped around the outside of the main line body 1 between the limiting pieces 10 on both sides. At this time, under the action of the limiting pieces 10 on both sides, the protective sleeve 3 can be restricted from being separated from the end of the main line body 1.

[0031] like Figure 1 , Figure 2As shown, a support frame 11 made of mica insulating material is arranged inside the main line body 1, and four independent accommodating cavities 12 are formed on the support frame 11, and the conductive cores 2 are respectively arranged in the corresponding accommodating cavities 12. The conductive cores 2 are separated by the support frame 11, so as to reduce the mutual interference of the conductive cores 2 during operation, and at the same time reduce the heat transfer between adjacent conductive cores 2. A high temperature resistant layer 13 is also arranged between the outer wall of the support frame 11 and the inner wall of the main line body 1, and the high temperature resistant layer 13 can be made of Teflon high temperature resistant material.

[0032] The implementation principle is:

[0033] When the surface of the main line body 1 needs to be cooled, the water pipe 4 is sequentially inserted into the perforation 31, and the water pipe 4 can be fixed outside the main line body 1 under the limit of the hanging ear 30. Then, cooling water is continuously introduced into the water inlet of the water pipe 4, and the cooling water flowing through the surface of the main line body 1 can take away the excess heat on the surface of the main line body 1, thereby effectively cooling the surface of the main line body 1. In addition, since the water pipe 4 is spirally wound around the outer wall of the protective sleeve 3, the contact area between the water pipe 4 and the surface of the main line body 1 can be increased, thereby ensuring the cooling effect on the surface of the main line body 1 and ensuring that the conductive core 2 can work normally.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
