Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an electric shock protection cable. Background Art

[0002] Cables are usually rope-like cables made of several or several groups of wires twisted together. Each group of wires is insulated from each other and often twisted around a central wire. The entire outside is covered with a highly insulating covering. The cable has internal power. Cables are one of the common circuit components used to transmit electricity, and cables can be laid underground or erected in the air.

[0003] When existing cables laid underground are used, the cables themselves are easily compressed by objects on the ground, and the wear-resistant layer on the outside of the cable is easily damaged by friction and compression during long-term use, causing the wear-resistant layer on the outside of the cable to break easily. The cable skin gradually falls off due to friction, exposing the inner core and causing the risk of cable leakage. For this reason, we propose an anti-electric shock cable. Utility Model Content

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides an electric shock protection cable.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anti-electric shock cable, comprising an inner core and an insulating layer, the outer sleeve of the insulating layer is provided with an anti-corrosion layer, the outer sleeve of the anti-corrosion layer is provided with a built-in wear-resistant layer, the outer sleeve of the built-in wear-resistant layer is provided with a wrapping layer, the interior of the wrapping layer is provided with a spring sheet sleeved on the outside of the built-in wear-resistant layer, the wrapping layer and the built-in wear-resistant layer are filled with an elastic filling material in contact with the inner and outer sides of the spring sheet, the outer sleeve of the wrapping layer is provided with a wear-resistant component, and the outer sleeve of the wear-resistant component is provided with an external wear-resistant layer.

[0006] Preferably, the spring sheet is a curved structure and has deformation characteristics, and the elastic filling material has deformation characteristics.

[0007] Preferably, the periphery of the spring sheet is in supporting contact with the inner side of the wrapping layer, and the inner side of the spring sheet is in supporting contact with the periphery of the built-in wear-resistant layer.

[0008] Preferably, when the external wear-resistant layer squeezes the spring piece through the wrapping layer, the spring piece is in a supporting and buffering state due to its own elasticity; when the spring piece is squeezed and deformed, the elastic filling material located inside the wrapping layer is in a supporting and buffering state for the spring piece.

[0009] Preferably, the wear-resistant component is composed of a wear-resistant steel wire mesh and a packaging material, and the wear-resistant steel wire mesh is located inside the packaging material and is packaged and formed integrally.

[0010] The utility model provides an anti-electric shock cable with the following beneficial effects:

[0011] 1. This is an anti-electric shock cable. In this article, the outer part of the built-in wear-resistant layer is provided with a wrapping layer, and the inside of the wrapping layer is provided with a spring piece wrapped around the outside of the built-in wear-resistant layer. When the cable is buried underground for use, the underground soil layer will squeeze the wear-resistant component and the external wear-resistant layer. When the squeezing force is transmitted to the outside of the wrapping layer, the wrapping layer can adapt to the squeezing of the spring piece, and the spring piece can perform deformation buffering through its own deformation characteristics. When the spring piece squeezes the elastic filling material during deformation, the elastic filling material can also perform deformation buffering at the same time, reducing the squeezing force on the inside of the built-in wear-resistant layer. In this way, the cable can buffer and reset the squeezing force brought by the external soil layer, avoiding long-term squeezing damage, thereby achieving the effect of preventing the cable sheath from being gradually compressed, damaged and falling off, and preventing the risk of leakage.

[0012] 2. This is an anti-electric shock cable, in which the outer sheath of the wrapping layer is wrapped with a wear-resistant component, the wear-resistant component is composed of a wear-resistant steel wire mesh and a packaging material, and the wear-resistant steel wire mesh is located inside the packaging material and is packaged as one piece. When the soil layer first squeezes the external wear-resistant layer, if the surface of the external wear-resistant layer is damaged due to long-term squeezing and friction, the wear-resistant component can block the squeezing force again, and the wear-resistant steel wire mesh inside the packaging material can be used for friction resistance due to its own characteristics, thereby achieving the effect of assisting in improving the quality of the cable.
