Problems solved by technology

[0003] The purpose of the present invention is to solve the problems that the existing semi-flexible coaxial cable shielding layer cannot achieve 100% braiding density, the gaps at the intersection points increase the difficulty of tin dipping, and at the same time, the tin layer is easy to fall off after repeated bending, which reduces the cable shielding efficiency. A method for manufacturing the shielding layer of a semi-flexible coaxial cable that can achieve 100% braiding density, is uniform and easy to soak in tin, and the tin layer is not easy to fall off after repeated bending

Abstract

The invention relates to a manufacturing method of a semi-flexible coaxial cable shielding layer. A semi-flexible coaxial cable comprises an inner conductor, an insulating layer, a shielding layer and a jacket layer, and the semi-flexible coaxial cable shielding layer is manufactured through unidirectionally winding a metal wire on an insulating ore and then carrying out dip soldering. The manufacturing method concretely comprises the following steps of: (1) setting winding parameters of the metal wire; (2) installing a pay-off spool on which the semi-flexible coaxial cable insulating core iswound, and arranging the insulating core; (3) installing a metal wire coil for winding, arranging the metal wire, and winding the metal wire on the insulating core; and (4) fluxing the wound shielding wire coil, drying, carrying out dip soldering, air cooling, and connecting with a second take-up spool assembled on a second take-up stand. The shielding layer is formed by unidirectionally winding the metal wire, the dip soldering is even, uniform and easy, and the tin layer can not fall off due to the relative sliding of interwoven metal wires in bending. The production efficiency is six timeshigher than the weaving efficiency, and the energy consumption of the manufacturing method only accounts for 1 / 24 of that of the weaving process. In addition, 100 percent of shielding can be realized.

Description

(1) Technical field [0001] The invention relates to a manufacturing method of a semi-flexible coaxial cable shielding layer. (2) Background technology [0002] Conventional coaxial cables are composed of inner conductors, insulating layers, shielding layers, and sheath layers. Due to the incompactness of the braided structure of the shielding layer itself, when the shielding attenuation requirements are strict in the case of bending, its cable performance cannot meet the requirements for use. , in order to make up for the lack of density of the braiding layer, a coaxial cable with a metal tube as the shielding layer, that is, a semi-rigid coaxial cable, has appeared, but this type of cable has poor bending performance and cannot be mass-produced continuously. The semi-flexible coaxial cable dipped in tin again solves the problems of bending and continuous production. However, since the shielding layer of this type of cable adopts a two-way cross braiding structure, there wil...
