AI Technical Summary

Technical Problem

Traditional cables have poor abrasion resistance, and the connection process is cumbersome and the sealing is insufficient, resulting in safety hazards and low construction efficiency.

Method used

The outer sheath uses nano-ceramic particle-reinforced fluororubber material as the wear-resistant layer, combined with a honeycomb sleeve made of glass fiber-reinforced modified polypropylene composite material. The inner lining and inner sheath use a copper conductor core made of high-purity oxygen-free copper material and a high-elasticity flame-retardant polyurethane foam strip filling layer. The connecting components achieve quick connection and efficient sealing through an insulating shell, conductive base, rotating plate and locking parts.

Benefits of technology

It improves the cable's wear resistance, extends its service life, simplifies the connection process, enhances sealing and conductivity stability, and reduces operational difficulty and safety hazards.

Abstract

The application provides a cable with good wear resistance and a connecting assembly thereof, and relates to the technical field of cables. The cable with good wear resistance comprises a cable main body and an outer sheath, the cable main body is arranged on the inner side of the outer sheath, and the outer side of the outer sheath is covered with a wear-resistant layer. The cable main body comprises an inner liner, the inner side of the inner liner is provided with three copper cores, the outer side of the copper core is fixedly provided with an inner sheath, the gap between the inner side of the inner liner and the inner sheath is filled with a filling layer, and the outer side of the inner liner is fixedly provided with a honeycomb sleeve, a plurality of honeycomb holes are uniformly arranged on the outer circumferential wall of the honeycomb sleeve. The wear-resistant layer on the outer side of the cable outer sheath is made of a nano ceramic particle reinforced fluororubber material, the material has excellent scratch resistance and wear resistance, can effectively resist the friction between the cable and the ground, the pipeline and the wall during laying and the external mechanical scratching during long-term use, and reduces the risk of damage of the outer sheath and exposure of the internal cable main body.
