Method for processing ribbon cable with shielding layer and sheath

Abstract

The invention discloses a method for processing a ribbon cable with a shielding layer and a sheath. The method comprise steps of 1), preparation of a cable core, multiple wires are sequentially washedby acid and the water, dried and then stranded to obtain an initial core body, and the initial conductor body is placed in a tin plating bath for tin plating to obtain a cable core; 2), preparation of a conductor, a shielding film is wound around a surface of the cable core to obtain a conductor; 3), preparation of the ribbon cable, after multiple conductors extend in the horizontal direction andare arranged to form a cable, an upper surface and a lower surface of the cable are respectively provided with a sheet, and the ribbon cable is obtained by hot pressing; the acid liquid at least includes the water, hydrochloric acid, magnesium chloride, ammonium chloride and sodium chloride; the shielding film includes at least a film in a sheet-like structure and mixed rubber compound disposed on a surface of the film opposite to the wrapping surface, and the mixed rubber compound is composed of mixture of semiconductive rubber and graphite. The method is advantaged in that the shielding layer and the sheath are both set, and the loosening prevention effect of the cable core is achieved.

Description

technical field [0001] The invention relates to the field of processing technology of flat cables, in particular to a processing method of flat cables with shielding layers and sheaths. Background technique [0002] Ribbon cable, customarily refers to strip-shaped parallel multi-core wires, such as gray cable, rainbow cable, high temperature cable, etc. Broadly speaking, ribbon cables should also include cable varieties such as flexible printed wires and flexible flat cables. Due to the flat structure and good performance of the ribbon cable, it is widely used in national defense, aerospace, digital communication, robotics, medical equipment, electronic equipment and other fields. [0003] However, during its manufacturing process, since it needs to undergo operations such as stranding and compression molding during processing, it is vulnerable to pressure during the extrusion process, resulting in loose deformation of multiple wires in the core. At the same time, it is no...
