Problems solved by technology
In mobile occasions, the cable with this structure has poor tensile strength, the conductor is prone to breakage, and the sheath layer has poor flexibility and is easy to be damaged, which shortens the service life of the cable, so it is not suitable for mobile occasions.
In addition, the cables used in environments subject to repeated bending such as automobiles require not only high bending durability but also high flexibility from the viewpoint of easy wiring. Existing cables cannot achieve high flexibility at the same time. Excellent bending durability and high flexibility
Thereby reducing the environmental adaptability of the cable

Embodiment Construction
[0012] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0013] see figure 1 , the present invention includes six insulated wire cores, fillers 1-3, a shielding layer 2 wrapped outside the six insulated wire cores, and a braided layer 3 and a sheath layer 4 arranged outside the shielding layer 2 in sequence.
[0014] Wherein, the insulated wire core is composed of a conductor 1-1 and an insulating layer 1-2 covered outside the conductor 1-1.
[0015] Six insulated wire cores are arranged around the fillers 1-3.
[0016] The central part of the cable of the present invention is the filler 1-3 instead of the insulated wire core. When the cable is bent, the pressure generated between the insulated wire cores is absorbed by the deformation of the filler 1-3. Therefore, the insulated wire core is relieved. ...

The invention discloses a cable with high tensile property. The cable comprises a plurality of insulation wire cores, a filling material, a shielding layer, a weaving layer and a sheath layer, wherein the weaving layer and the sheath layer are sequentially arranged at the exterior of the shielding layer, each insulation wire core comprises a conductor and an insulation layer which coats the exterior of the conductor, the insulation wire cores are arranged around the filling material, the shielding layer coats the exteriors of the insulation wire cores, each conductor is made of copper-clad steel material, the shielding layer is made of copper-clad aluminum wires, the weaving layer is made of polyvinyl plastic material, and the sheath layer is made of thermoplastic elastomer material. The cable has the advantages that each conductor can bear larger tensile force, and is suitable for mobile environments; the insulation wire cores are arranged around the filling material, so the cable has the bending durability and winding property, and can be used in the repeated bending environment; the environment suitability of the cable is improved.
Description
technical field [0001] The invention relates to a cable which can be used in moving occasions and repeated bending conditions. Background technique [0002] The existing cable structure includes four parts: a plurality of conductors, an insulating layer covering the outside of each conductor, a braiding layer and a sheath layer, wherein the conductor and the insulating layer form an insulated core. [0003] At present, the conductor of most cables is made of bare copper wire, and the material used for the sheath layer is ordinary polyvinyl chloride plastic. In mobile situations, the cable with this structure has poor tensile strength, the conductor is prone to breakage, and the sheath layer has poor flexibility and is easily damaged, which shortens the service life of the cable, so it is not suitable for mobile situations. In addition, the cables used in environments subject to repeated bending such as automobiles require not only high bending durability but also hig...
