Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an impact-resistant composite cable. Background Art

[0002] A cable is a wire made of one or more mutually insulated conductors and an outer insulating protective layer, and is laid underground, in the air, etc.

[0003] As disclosed in the patent CN215770608U, a shock-resistant cable, there is a problem in the prior art that when the cable is subjected to external force impact during the transportation and laying of the cable, even if the outermost insulation layer can play a certain impact resistance role, it is very likely that the wires inside the cable will be deformed and damaged due to excessive impact force, thereby causing the cable to fail to work normally and reduce its service life. In order to solve such problems, the present application proposes a cable with a new structure. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides an impact-resistant composite cable.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A shock-resistant composite cable comprises a cable sheath, wherein a plurality of cable conductors are arranged in the cable sheath, the cable sheath comprises a flame-retardant layer, a buffer layer is glued to the outer side of the flame-retardant layer, the cable sheath is filled with a filling layer, the outer sides of the plurality of cable conductors are all sheathed with an insulating layer, the buffer layer comprises a plurality of first buffer strips, a second buffer strip is glued between two adjacent first buffer strips, the first buffer strips and the second buffer strips are alternately distributed, and a wear-resistant coating is arranged on the outer side of the buffer layer.

[0007] As a further solution of the present invention, the material of the filling layer is tetrafluoroethylene.

[0008] As a further solution of the present invention, the flame retardant layer is made of polyvinyl chloride.

[0009] As a further solution of the utility model, the insulating layer is made of polyperfluoroethylene propylene.

[0010] As a further solution of the utility model, a shielding layer is glued to the outer side of the insulating layer, and the shielding layer is a copper tape.

[0011] The beneficial effects of the utility model are:

[0012] 1. Through the setting of the buffer layer and the filling layer, the filling layer fills the inside of the cable sheath, so that the inside of the cable sheath can be in a saturated state. When the cable is hit, the outermost buffer layer will play an impact-resistant role, and the filling layer will also play an impact-resistant role, thereby protecting the conductor inside the cable, avoiding deformation and damage of the wire inside the cable due to excessive impact force, and improving the impact resistance of the cable.

[0013] 2. Through the setting of the flame retardant layer, the flame retardant layer has a flame retardant effect, which can prevent the cable from burning and causing damage to the cable, thereby improving the flame retardant performance of the cable.

[0014] 3. Through the setting of the shielding layer, the shielding layer can shield the external interference to the cable conductor, thereby making the cable more stable and improving the use effect of the cable. BRIEF DESCRIPTION OF THE DRAWINGS
