Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cables, in particular to a cable with a protective function. Background Art
[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. It is made of one or more mutually insulated conductors and an outer insulating protective layer, and transmits electricity or information from one place to another. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple strands of wires and insulating layers, and are used to connect circuits, electrical appliances, etc. The derivative products of wires and cables are mainly produced by using new materials, special materials, changing product structure, improving process requirements, or combining different varieties of products due to different application occasions, application requirements, equipment convenience, and requirements for reducing equipment costs. When existing cables are buried underground, they are easily damaged by external factors such as extrusion and rodents gnawing. Once the protective layer is damaged or corroded, the service life of the cable will be greatly reduced, and the cables passing through the inside will be easily damaged, affecting normal use. Utility Model Content
[0003] The main purpose of the utility model is to provide a cable with a protective function, which can effectively solve the problems in the background technology.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] Preferably, the outer protective layer of the cable is made of wear-resistant rubber material, and the outer protective layer, irritant layer, armor protective layer and inner protective layer of the cable are fitted together.
[0007] Preferably, the odor-dissipating holes are evenly arranged, the irritant layer is made of a material with a strong odor, and the armor protection layer is made of metal.
[0008] Preferably, the inner protective layer is made of insulating rubber material, the six groups of support plates are evenly arranged in a circle, and the six groups of support plates and the isolation ring are an integral structure.
[0009] Preferably, the six groups of spring pieces are arranged in an arc shape, and the spring pieces are made of insulating material.
[0010] Preferably, several groups of cable core wires are isolated from each other.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. Through several groups of odor-dissipating holes opened on the inner side of the outer protective layer of the cable, the strong irritating smell of the irritant layer is emitted to prevent small animals such as mice and mosquitoes from approaching, drive away rodents, and prevent rodents from gnawing on the cables. In addition, according to several groups of cable core wires set independently of each other and the flame-retardant fillers set on the outside, the heat between the several groups of cable core wires will not be transferred, and the heat will be dispersed. Even if one group of cable core wires overheats and ignites, it will not spread, and the purpose of automatic extinguishing is achieved due to the interference of the flame-retardant filler.
[0013] 2. When the external force is too large, the cable core wire is pressed by the external force, and then the cable core wire will compress the corresponding set of spring pieces inward, thereby reducing the force on the cable core wire. When the external force is withdrawn, the cable core wire is reset according to the elastic effect of the spring pieces, so that it can be repeatedly used after subsequent pressure, thereby avoiding damage to the cable due to external force factors, improving the protection of the cable, and thus extending the service life of the cable.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] like Figure 1-3 As shown, a cable with a protective function comprises a cable outer protective layer 1, a plurality of groups of odor dissipation holes 2 are opened inside the cable outer protective layer 1, a stimulant layer 3 is fixedly connected to the inner side of the cable outer protective layer 1, an armored protective layer 4 is fixedly arranged on the inner side of the stimulant layer 3, an inner protective layer 5 is fixedly connected to the inner side of the armored protective layer 4, six groups of support plates 6 are fixedly arranged on the inner side of the inner protective layer 5, isolation rings 7 are fixedly connected to the inner sides of the six groups of support plates 6, six groups of spring pieces 8 are fixedly arranged between the six groups of support plates 6, cable core wires 9 are movably arranged on the inner side of the isolation ring 7 and the outer sides of the six groups of spring pieces 8, and the outer sides of the plurality of groups of cable core wires 9 are filled with flame retardant fillers 10.
[0020] In this embodiment, the outer protective layer 1 of the cable is made of wear-resistant rubber material, the outer protective layer 1 of the cable, the irritant layer 3, the armored protective layer 4, and the inner protective layer 5 are fitted together, the odor holes 2 are evenly arranged, the irritant layer 3 is made of a material with a strong odor, the armored protective layer 4 is made of metal, the inner protective layer 5 is made of insulating rubber material, the six groups of support plates 6 are evenly arranged in a circle, the six groups of support plates 6 and the isolation ring 7 are an integrated structure, the six groups of spring plates 8 are arc-shaped, the spring plates 8 are made of insulating material, and several groups of cable core wires 9 are isolated from each other.
[0021] Specifically, firstly, the strong irritating smell of the irritant layer 3 is emitted through a plurality of groups of odor dissipation holes 2 opened on the inner side of the cable outer protective layer 1, so as to prevent small animals such as mice and mosquitoes from approaching, drive away rodents, and prevent rodents from gnawing the cable. In addition, the relatively hard metal material of the armored protective layer 4 can prevent the internal cable from being squeezed by external force and corrosion damage caused by long-term soil burial. When the external force is too large, the cable core wire 9 is pressed by external force, and then the cable core wire 9 will compress the corresponding group of spring pieces 8 inward, thereby reducing the damage to the cable core wire 9. When the external force is withdrawn, the cable core wire 9 is reset according to the elastic action of the spring piece 8, so that it can be repeatedly used after being compressed, thereby avoiding damage to the cable due to external force factors, improving the protection of the cable, and thus prolonging the service life of the cable. In addition, according to the several groups of cable core wires 9 independently arranged, and the flame retardant filler 10 arranged on the outside thereof, the heat between the several groups of cable core wires 9 will not be transferred, and the heat will be dispersed. Even if one group of cable core wires 9 overheats and ignites, it will not spread, and the purpose of automatic extinguishing is achieved due to the interference of the flame retardant filler 10.

In addition, the relatively hard metal material of the armored protective layer 4 prevents the internal cable from being squeezed by external force and corrosion damage caused by long-term soil burial. When the external force is too large, the cable core 9 is pressed by external force, and then the cable core 9 will compress the corresponding group of shrapnel 8 inward, thereby reducing the cable core 9 from being subjected to When the external force is withdrawn, the cable core wire 9 is reset according to the elastic action of the spring piece 8, so that it can be repeatedly used after being compressed, thereby avoiding damage to the cable due to external force factors, improving the protection of the cable, and thus prolonging the service life of the cable.
