Longitudinal wrapping mold for outer conductor of radiation leaky cable and method for forming outer conductor

Abstract

The invention relates to a radiation leaky cable outer conductor longitudinal package mold and a longitudinal package forming method. The longitudinal package mold comprises a mold body. The mold body comprises a trumpet-shaped cloth bag tube which is formed by winding double-layer cloth and a fixing part which is used for fixing the cloth bag tube. The cloth bag tube comprises a first passage which is formed between the double-layer cloth and a wound second passage. An outer conductor passes through the first passage. A cable core passes through the second passage. The longitudinal package forming method provided by the invention comprises the steps that the longitudinal package mold enables the belt-like outer conductor and the cable core to run into the entrance of the first passage and the second passage through continuous application of traction force; the outer conductor and the cable core walk in the first passage and the second passage and run out of the exit; when the belt-like outer conductor walks in the first channel, the belt-like outer conductor gradually forms a cylinder with the cloth bag tube; and the cylindrical outer conductor at the exit wraps the cable core. According to the longitudinal package mold and the method, the slot hole of the outer conductor is not easily deformed.

Description

technical field [0001] The invention relates to a longitudinal wrapping mold for an outer conductor of a radiation leaky cable and a forming method for the outer conductor. Background technique [0002] At present, the longitudinal wrapping dies commonly used for the outer conductor of radial leaky cables generally adopt the longitudinal wrapping dies rolled from steel plates or the longitudinal wrapping dies formed by machining steel materials. The mold belongs to forced longitudinal wrapping, and the formed strip is subjected to a large force during the forming process. Since the copper tape of the outer conductor of the radiation-type leaky cable is punched with slots, its structure is uneven, and stress concentration tends to occur around the slots when the force is applied, resulting in deformation of the slots. The deformed slot leads to serious degradation of the coupling loss of the radial leaky cable. This kind of technological problem has been perplexing the tech...
