A special shielded cable and its sheath shape trimming machine

Abstract

The invention relates to a special shielded cable and a machine for trimming the shape of its sheath. It includes a cable assembly. The cable assembly is arranged in a flat shape and has a plurality of wire cores arranged inside. The outer sheath of the wire cores is provided with an insulating layer. The outer sheath of the insulating layer is provided with an outer sheath whose opposite two sides can be engaged with each other, and a liquid containing chamber is arranged between the two. In the present invention, outer sheaths that can be clamped to each other on the left and right sides are sheathed on the outside of the cable assembly, and a liquid chamber in which internal solutions can communicate with each other is set between the outer sheath and the insulating layer, so that the flat cable is divided into left and right sides. The enclosure of the side forms a ring-shaped cable, so as to adapt to the original round cable use environment. At the same time, because the slots where the outer sheaths are connected to each other are divided into several parts by the gap, the part of the flat cable can be changed into a ring shape. The flexibility of the entire cable is increased without complete deformation, and the purpose of splicing adjacent flat cables can also be achieved, so that the flat cables can be added.

Description

technical field [0001] The invention relates to the field of cable processing, in particular to a special shielded cable and a sheath shape trimming machine. Background technique [0002] Shielded cable refers to a cable with metal wire braiding or metal tape outer covering shielding layer, which has electromagnetic shielding performance. It is suitable for transformers and similar equipment that need to shield electromagnetic signals. Cable shielding means that the outer mesh braided wire of the cable has been grounded at one end, so that the external electromagnetic radiation and magnetic field radiation can directly enter the ground without interfering with the inner layer wires. Generally used for lines with high frequency and low signal level, such as cable TV, lead wires from inverter to motor, analog lead wires, and some interference transmission lines, such as computer shielded cables. As long as the cable with shielding layer is called shielded cable, power cable ...

AI Technical Summary

Problems solved by technology

[0003] Existing flat cables have been fixed in specification, so it is impossible to add wires or combine wires when necessary. At the same time, when flat cables need to be perforated or piped, or when the original round cables are replaced with flat cables, it is not possible. easy to use
