Problems solved by technology

However, there has always been a technical bottleneck in the manufacture of this cable. Since the outer conductor is formed by manually inserting the core wire into the outer copper tube, the processing method is primitive, resulting in the inability to produce continuously and in large lengths, especially for a single manufacturing length. At the same time, there are problems such as unstable product quality, low production efficiency and large waste, which cannot effectively meet the needs of the communication market for high-quality semi-rigid cables.

Embodiment 1

[0018] Embodiment 1: Taking the pure copper outer conductor semi-rigid radio frequency cable RG402 as an example, the specific process steps are as follows:

[0019] (1) First, install the pushed and qualified Φ2.53mm core wire on the pay-off stand, and adjust the pay-off tension to 10N for stable control of production. The core wire includes an inner conductor and an insulating layer;

[0020] (2) Copper tape unwinding: In order to facilitate subsequent rolling of copper strips, vertical unwinding equipment is used for unwinding copper strips. Put the disc-shaped copper strips upright on the tape reel, and adjust the shaft hole of the tape reel at the same time. The outer diameter is to meet the requirements of different copper strips, and the strip equipment adopts the active strip release method; Copper strip rolling: put the copper strip on the strip reel between the two rolling wheels on the copper strip rolling machine Rolling according to different needs. The spacing of...

Abstract

The invention discloses a machining process for an outer conductor of a semi-rigid cable. The semi-rigid cable comprises an inner conductor, an insulating layer and the outer conductor. The machining process comprises the following steps of firstly, mounting a pressed and qualified cable core of phi 2.53 mm on a pay-off rack, secondly, mounting a metal band on a band pay-off rack, adjusting band pay-off tension to be 15-30 N, carrying out side cutting on the metal band, then carrying out forming through a horn die, starting a laser welding machine for welding and debugging, threading the cable core of phi 2.53 mm into the metal band for wrapping, forming, welding and sizing after the welding and the debugging. The semi-rigid cable produced thought the machining process is small in radio frequency leakage and stable in performance, quality stability, production length and the manufacturing process are improved greatly, process losses are reduced greatly, and production cost is lowered effectively.

Description

technical field [0001] The invention relates to a cable manufacturing process, in particular to a process for processing the outer conductor of a semi-rigid cable. [0002] Background technique [0003] With the development of my country's communication industry, the frequency of cable transmission is becoming more and more high-frequency, and with it, various cables are more and more used as high-frequency and ultra-high-frequency connecting lines for microwave, radio frequency and other radio equipment. middle. However, there has always been a technical bottleneck in the manufacture of this cable. Since the outer conductor is formed by manually inserting the core wire into the outer copper tube, the processing method is primitive, resulting in the inability to produce continuously and in large lengths, especially for a single manufacturing length. At the same time, there are problems such as unstable product quality, low production efficiency and large waste, which cannot...
