Novel outer conductor embossing mould of super-flexible 1/2 feeder line cable, and method thereof

Abstract

The invention discloses a novel outer conductor embossing mould of a super-flexible 1 / 2 feeder line cable, and a method thereof, and relates to the field of cable embossing moulds. The novel outer conductor embossing mould comprises an embossing head which rotates concentrically, wherein an embossing ring is arranged in the embossing head; and the center line of the embossing ring and the center line of the embossing head are not the same line. The embossing method comprises the following steps that the embossing ring is grinded into a regular annular mould; the embossing ring grinded in the step S1 is installed in the embossing head, wherein the embossing ring can freely move in the embossing head; and a novel outer conductor of the super-flexible 1 / 2 feeder line cable is pumped into theembossing ring to finish embossing. According to the mould, an inner hole edge of the embossing ring and the center line of the embossing ring are vertically arranged, so that the contact surface of the embossed cutting edge is small in the embossing process, the embossing resistance is much smaller than that in the prior art, the regular embossing textures can be formed smoothly even if in conditions of a relatively thick or hard copper tube, or a relatively thin or soft copper tube, and the embossing textures can be formed easily.

Description

technical field [0001] The invention relates to the field of cable embossing dies, in particular to a novel outer conductor embossing die for a super-flexible 1 / 2" feeder cable and a method thereof. Background technique [0002] The ultra-flexible 1 / 2" feeder cable is a feeder cable with the model HCAHY(Z)-50-9 in the Chinese communication industry standard YD / T1092-2013, because its outer conductor embossing pitch is smaller than that of ordinary feeder cables and the wire diameter Smaller, so that it not only has good electrical performance and strict communication security of ordinary feeder cables, but also has superior physical properties such as compression resistance and bending, and high signal use cut-off frequency. Cables are very useful in various environments Good communication effect, widely used in all aspects of mobile communication construction. [0003] The ultra-flexible 1 / 2" cable is composed of four parts: inner conductor, insulating layer, outer conduct...

Problems solved by technology

[0007] like Image 6 As shown in the installation method of the embossed ring, the embossed ring is installed concentrically in the embossed head, but a fixed mold that conforms to the shape of the embossed ring needs to be processed on the side of the installation, and the irregular shape is not easy to process
