[0002] Cable is a general term for optical cables, electrical cables, etc. Cables have many uses, mainly used for controlling installation, connecting equipment, transmitting electricity, and other multiple functions. They are common and indispensable in daily life.

[0003] Existing traditional cables usually use thinner rubber sheaths and insulating protective sheaths to cover the outer wall of the wire core. The cables are often squeezed and bent during use. During the squeezing and bending process, the cables are damaged or broken due to their own insufficient strength or toughness, posing a safety hazard and affecting the service life of the cables.

[0013] 1. This kind of high-toughness and bending-resistant cable, by setting tough rubber columns, insulating rubber strips and reinforcing cores, can improve the compression resistance and toughness of the cable by using tough rubber columns, and can improve the bending resistance and toughness of the cable by spirally winding insulating rubber strips on the insulating layer.

The plurality of elastic sheets 302 are evenly distributed in an array along the circumference. When the cable is squeezed, the pressure acting on the protective sleeve 1 will be dispersed to the plurality of elastic sheets 302, and then dispersed to the flame-retardant rubber filling layer 301 through the plurality of elastic sheets 302, so that the external force acting on the cable can be dispersed, the damage to the internal structure of the cable can be reduced, and the pressure resistance of the cable can be improved.
