Fireproof and waterproof cable assembly

Abstract

The invention provides a fireproof and waterproof cable assembly, which comprises a cable joint and a cable body detachably connected with the cable joint, and is characterized in that two ends of thecable body are connected with the cable joint; and the cable body comprises an insulating layer, a central cable wrapped by the insulating layer, and a plurality of peripheral cables surrounding thecentral cable. Each of the central cable and the plurality of peripheral cables comprises a central conductor and an insulating waterproof layer wrapping the central conductor. The insulating waterproof layer is provided with a heat dissipation piece, the heat dissipation piece comprises an elastic isolation piece which is in a spiral ascending shape, the isolation piece is provided with a plurality of supporting pieces at intervals in the spiral ascending direction, and the central cable and the peripheral cables penetrate through the supporting pieces. The technical problem that when heat ofan insulating layer is accumulated to the melting point of the insulating layer, spontaneous combustion occurs, and adjacent cables are further ignited is solved.

Description

technical field [0001] The invention relates to the technical field of cable assemblies, in particular to a fireproof and waterproof cable assembly. Background technique [0002] With the development of electronic technology, cable accessories are more and more widely used in the electronic communication industry. Cable assemblies are used to connect different electronic equipment systems or electrical connection components between systems. The general cable assembly is composed of a cable and connectors arranged at both ends of the cable. [0003] With the wide application of cable assemblies in the field of communication, the requirements for the stability of the electrical performance of cable assemblies, service life and environmental resistance are also getting higher and higher. At present, during the use of commonly used cable assemblies, the internal carrying capacity of the cables is too large. When the cable heats up, the insulating layer in contact with it will t...

Problems solved by technology

[0003] With the wide application of cable assemblies in the field of communication, the requirements for the stability of the electrical performance of cable assemblies, service life and environmental resistance are also getting higher and higher. At present, during the use of commonly used cable assemblies, the internal carrying capacity of the cables is too large. It will cause the cable to heat up, and the insulating layer in contact with it will transfer the heat. When the heat of the insulating layer accumulates to its own melting point, spontaneous combustion will occur, further igniting the adjacent cables, and it is easy to cause a fire.
