Wear resistant weak current cable

Abstract

The invention discloses a wear-resistant weak current cable, which comprises a cable, an outer sheath is fixedly connected to the surface of the cable, a steel wire coil is connected to the inner side of the outer sheath, and the outer sheath There is an inner lining layer connected with the steel wire winding coil, the inner side of the steel wire winding coil is connected with a steel-plastic composite tape, the inner side of the steel-plastic composite tape is connected with a cable core filler, and the inner side of the cable core filler is connected with an inner Layer sleeve, the inner side of the inner layer sleeve is connected with an aluminum-plastic composite tape, the inner side of the aluminum-plastic composite tape is connected with a lead sleeve, the outer side of the lead sleeve is connected with a rolling strip, the first wire, the second wire, A central element strengthener is connected between the third wire and the fourth wire. The present invention can be pulled up in the cable through the central element strengthener, and secondly, the parallelism and stretchability of the cable are strengthened, and the four wires can be blocked from contacting each other, so as to avoid the damage of the wire when stretching. The cable is pulled.

Description

technical field [0001] The invention relates to the technical field of weak current cables, in particular to a wear-resistant weak current cable. Background technique [0002] Weak current cables refer to cables used for security communication, electrical equipment and related weak current transmission purposes. There is no strict boundary between "wire" and "cable". Usually, products with few cores, small product diameter and simple structure are called electric wires, those without insulation are called bare wires, and others are called cables; Small (less than or equal to 6 square millimeters) are called small wires, and insulated wires are also called wiring wires. Video signal transmission generally uses direct modulation technology in the form of baseband frequency (about 8MHz bandwidth). The most commonly used transmission medium is coaxial Cable; coaxial cable is specially designed to transmit video signals, and its frequency loss, image distortion and image attenu...

Problems solved by technology

Usually, products with few cores, small product diameter and simple structure are called electric wires, those without insulation are called bare wires, and others are called cables; Small (less than or equal to 6 square millimeters) are called small wires, and insulated wires are also called wiring wires. Video signal transmission generally uses direct modulation technology in the form of baseband frequency (about 8MHz bandwidth). The most commonly used transmission medium is coaxial Cable; coaxial cable is specially designed to transmit video signals, and its frequency loss, image distortion and image attenuation are relatively small, and it can well complete the task of transmitting video signals. The cables currently sold on the market, It is poor in wear resistance, tensile resistance and water resistance, and its application in long-distance communication, inter-office communication and harsh environments does not achieve ideal results.
