Pipe combined coaxial cable and manufacturing method thereof

Abstract

The invention relates to a pipeline combined coaxial cable and a making method thereof. The invention aims to provide a cable having the characteristics of simple structure, novel design and convenient maintenance and update and a method having the characteristics of simple process and reliable product quality. According to the technical scheme, the pipeline combined coaxial cable comprises a main cable and an auxiliary cable, wherein the outer sheath of the main cable and the sheath of the auxiliary cable are connected as a whole. The pipeline combined coaxial cable is characterized in that the cable further comprises a tubular hollow pipe parallel to the coaxial cable, and the hollow pipe and the outer sheath of the main cable are connected as a whole. The making method of the pipeline combined coaxial cable comprises the following steps: (1) a main cable and an auxiliary cable are paid off through a pay-off rack, and extend into a sheath mold of an extruder; (2) the cable core hole of the sheath mold is kept in a vacuum state, and pressurized gas is input into the liner of a hollow pipe; (3) a cable material is heated and molten through the extruder, and is integrally molded into the outer sheath of the main cable, the sheath of the auxiliary cable and the hollow pipe through the sheath mold; and (4) the cable is cooled by a gradient cooler.

Description

technical field [0001] The invention relates to the field of wire and cable product manufacturing, in particular to a pipe-combined coaxial cable and a manufacturing method thereof. Background technique [0002] With the advancement of science and technology, the replacement of products is also very rapid. For products in the field of wire and cable, it often happens that the product cannot meet the requirements after being submitted and operated for a period of time. Specifically, it includes the following two deficiencies : [0003] 1. The later maintenance cost of the cable is high, and the maintenance project is difficult; for example, if the installed indoor wiring fails and needs to be repaired, the existing interior decoration needs to be destroyed and reorganized or the existing wiring style needs to be changed; [0004] 2. The structural design of the existing wire and cable products is relatively rigid, and it is still traditional thinking. The function and utilit...

Problems solved by technology

[0003] 1. The maintenance cost of the cable is high in the later period, and the maintenance project is difficult; for example, if the installed indoor wiring fails and needs to be repaired, the existing interior decoration needs to be destroyed and reorganized or the existing wiring style needs to be changed;

[0004] 2. The structural design of the existing wire and cable products is relatively rigid, and it is still traditional thinking. The function and utility of the cable can only meet the present, and cannot take into account the future; if users have new functional requirements, they need to update the cable specifications. At the same time It will also result in a larger secondary investment
