Description

Technical Field

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

[0002] Cable is a general term for items such as optical cables and electrical cables. It is mainly used for multiple functions such as control installation, connecting equipment, and transmitting electricity. Cables are composed of copper wire conductors isolated by insulating materials. Outside the inner layer of insulating material is another layer of ring conductor and its insulator, and then the entire cable is wrapped by a sheath of polyvinyl chloride or Teflon material.

[0003] The publication number is CN209561023U, and the name is a compression-resistant cable with a reinforced wire loop, including a cable body, wherein the cable body includes a wire skeleton, a wire core, an insulating layer, an elastic plastic layer, a heat dissipation layer, a fireproof layer and a cable outer layer. The three wire cores are arranged in a triangular bundle, which makes the structure more stable and has good compression resistance. The outside of the three wire cores is hot-melt bonded with a wire skeleton, and the wire skeleton is an elastic rubber body, which makes the cable body have good flexibility.

[0004] However, the above-mentioned method of performing compression resistance operation on the cable is to add a wire skeleton, a wire core, an insulating layer, an elastic plastic layer, a heat dissipation layer, a fireproof layer and a cable outer layer to the outside of the cable to form a compression resistance layer to perform compression resistance operation on the cable. However, the compression resistance layer lacks buffering and shock absorption equipment and is still applied to the outside of the cable. The extrusion force is partially absorbed by the compression resistance layer, and part of it will be transmitted to the cable, causing the cable to be damaged by the force. Utility Model Content
