Description

Technical Field

[0001] The utility model relates to the field of cables, in particular to a wear-resistant cable with an anti-bending structure. Background Art

[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. With the rapid development of the communications industry in the past two decades, cable products have also developed at an astonishing speed, from simple telephone and telegraph cables in the past to thousands of pairs of telephone cables, coaxial cables, optical cables, data cables, and even combined communication cables. The application of cables is becoming more and more extensive, and the environment in which they are located is becoming more and more complex and diverse.

[0003] When workers are laying cables, it is easy for the outer sheath to be scratched during the laying process. The cable is easy to be bent and pulled arbitrarily during use, which can easily cause core breakage, leaving safety hazards and leading to accidents. At the same time, due to the poor resilience of the cable, when the cable is bent or squeezed, it is easy to cause deformation and damage at the bends and squeezes, thereby affecting the service life of the cable.

[0006] The inner core layer comprises a wire core and a wire core protection sleeve arranged outside the wire core.

[0007] The outer sheath layer includes an inner sheath and an outer sheath.

[0008] The outer sheath is provided with truncation grooves at intervals, and the notches of the truncation grooves are provided with fluorescent identification strips.
