Embodiment 1

[0033] Please refer to the attached figure 1 , figure 1 The structure of the power signal composite cable provided by Embodiment 1 of the present invention is shown.

[0034] figure 1 The power signal composite cable shown includes a signal wire 13 , a live wire 14 , a ground wire 15 and a layer of outer sheath 11 sealed with plastic. Wherein, the plastic-molded outer sheath 11 covers the cable bundle formed by the signal wire 13 , the live wire 14 and the ground wire 15 .

[0035] The plastic-encapsulated outer sheath 11 is the peripheral protective part of the entire power signal composite cable. Usually, the plastic-molded outer sheath 11 can be made of PVC (Polyvinylchloride, polyvinyl chloride), LSZH (Low Smoke Zero Halogen, low smoke zero halogen) material or PE (polyethylene, polyethylene) material. Of course, the plastic-molded outer sheath 11 can also be made of other materials, and this application does not limit the material of the plastic-molded outer sheath 11...

Abstract

The invention belongs to the technical field of communication, and discloses a power signal composite cable comprising a signal wire, a live wire and a ground wire, and a sealing plastic external sheath which wraps a cable bundle formed by the signal wire, the live wire and the ground wire. The live wire, the ground wire and the signal wire are uniformly distributed, and difference of external diameter of any two of the live wire, the ground wire and the signal wire is less than 1mm. The external diameter dimension of the signal wire, the ground wire and the live wire of the power signal composite cable is relatively balanced, and the signal wire, the ground wire and the live wire are uniformly distributed. When external force is applied to the whole power signal composite cable, force borne by the signal wire, the ground wire and the live wire is relatively uniform so that a problem of stress concentration caused by large dimension difference and non-uniform spatial distribution of the signal wire, the ground wire and the live wire can be avoided, and problems of reduction of wiring reliability and module fatigue damage caused by unbalanced internal stress after the power signal composite cable is connected with a butting module can be solved.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, relates to a power signal composite cable. Background technique [0002] With the rapid development of data communication technology and information technology, the performance requirements of the network for the integrated wiring system are getting higher and higher. In the current network cabling system, cables and signal cables are laid separately, which will lead to dense and disorderly cables, high cable laying costs, and complicated laying construction. Therefore, it is increasingly unsuitable for the wiring requirements of new technology development. Instead, the power signal composite cable is more and more used in the network cabling system. The power signal composite cable refers to a cable that integrates signal lines and transmission lines formed by adding insulated conductors to the signal cable. The power signal composite cable can solve the pr...
