A wall-penetrating cable and its protection device

Abstract

The invention mainly discloses a wall-penetrating cable and its protection device. The wall-penetrating cable includes several mutually insulated wires, and several rubber rings are arranged on the outside of the wires, and an elastic fiber net layer is arranged on the outside of the rubber ring. A corrugated outer insulating layer is arranged on the outside of the fiber mesh layer, a first deformation hole is arranged at the peak of the outer insulating layer, a shielding layer is arranged on the outside of the outer insulating layer, and a supporting frame is arranged between the shielding layer and the outer insulating layer; The protection device for the through-wall cable includes a sheath body wrapped outside the above-mentioned through-wall cable, a cable hole is arranged in the center of the sheath body, and a waterproof layer and a limit strip are arranged on the inner wall of the cable hole. A plurality of cooling pipes and second deformation holes are provided on the sheath body, the cooling pipes are filled with cooling liquid, and a reinforcement layer is provided outside the sheath body. The wall-through cable of the present invention has high compressive and torsion-resistant properties, strong connection stability between the protection device and the wall-through cable, and good heat dissipation and protection performance for the wall-through cable.

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...
