Through-wall cable and protection device thereof

Abstract

The invention mainly discloses a through-wall cable and a protection device thereof, and the through-wall cable comprises a plurality of mutually insulated wires, a plurality of rubber rings arrangedoutside the wires, an elastic fiber net layer arranged outside the rubber rings, a wavy outer insulation layer arranged outside the elastic fiber net layer, and first deformation holes arranged at wave crests of the outer insulation layer. A shielding layer is arranged outside the outer insulating layer, and a supporting framework is arranged between the shielding layer and the outer insulating layer; and the protection device of the through-wall cable comprises a sheath body wrapping the through-wall cable, a cable hole is formed in the center of the sheath body, a waterproof layer and limiting strips are arranged on the inner wall of the cable hole, a plurality of cooling pipes and second deformation holes are formed in the sheath body, the cooling pipes are filled with cooling liquid, and a reinforcing layer is arranged outside the sheath body. The through-wall cable has high compression resistance and torsion resistance, the connection stability between the protection device and the through-wall cable is high, and the heat dissipation and protection performance of the through-wall cable is good.

Description

technical field [0001] The invention relates to the technical field of wall-penetrating cables for electronic information transmission, in particular to a wall-penetrating cable and a protection device thereof. Background technique [0002] At present, communication plays an important role in various industries. In the modern command and command communication system, especially digital electronic information integrates multiple emerging technologies such as information, multimedia, network communication, and system management, a wide variety of electronic information equipment needs to be used. These electronic information equipment will pass through antennas, grounding systems, Various cables such as power supply systems and interconnection bus systems transmit information and power. Therefore, cables used to connect various electronic information devices are very important. In addition to the layout of cables indoors, they often encounter layouts that need to pass through...

AI Technical Summary

Problems solved by technology

The existing cables that need to pass through the wall have insufficient structural strength, and the cables have weak compressive and torsion resistance, especially in the parts near the wall, which are prone to rupture due to torsion and bending, reducing the use of cables. In order to protect the cable through the wall and its aesthetics, a protective device for protecting the cable is usually installed in the wall to improve the cable's compression resistance and prevent the cable from being damaged by rain, reptiles, etc.

The existing protective devices for protecting cables have a simple structure, and the connection structure with the cables is not stable, and only serves as a simple support protection, and the sealing performance is not good, not only the effect of dustproof and insectproof is poor , and the cable has a lot of wires inside, a large current carrying capacity, and generates a lot of heat. It is sealed in the wall, so the heat is not easy to dissipate, and it is easy to affect the normal work of the cable.
