AI Technical Summary
Existing communication cables require cable ties, wire clips, or cable reels for installation and storage, which makes construction inconvenient and they cannot shrink on their own, making them inconvenient to carry.
Design a spring-type magnetic communication cable with a protective sheath made of rare-earth permanent magnet flame-retardant thermoplastic elastomer material, which makes the cable magnetic and elastic, capable of self-contraction, and fixed to the cabinet or attracted to each other by magnetic attraction, avoiding the use of additional fasteners.
It enables simple construction and convenient disassembly without the need for additional fasteners. The cable can retract itself, making it easy to carry and store, thus improving construction efficiency and ease of use.
