Description

Wire harness for security monitoring equipment

Technical Field

The utility model relates to the technical field of cables, in particular to a wire harness for security monitoring equipment.

Background

Under the condition of using the cable conductor, the process or the phenomenon of short can appear usually to the cable conductor, bring very inconvenience for the staff, so need use a ground security protection monitoring cable conductor that has the spiral form.

Some security protection wire harnesses for supervisory equipment on the existing market:

(1) under the condition of using the cable, the cable is inconvenient to use due to the phenomenon that the cable is short or the process can occur, and the existing cable does not have a telescopic function.

(2) In the process of using the cable, because the air leakage phenomenon is easy to occur between the plastic-coated layer formed by plastic coating and the insulating layer, the sealing performance of the existing cable is poorer,

therefore, we propose a wire harness for security monitoring equipment in order to solve the problems set forth above.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved
