Multicore composite shield cable

Abstract

The invention discloses a multicore composite shield cable. The multicore composite shield cable comprises a central unshielded conductor, internal shield conductors, internal unshielded conductors and external shield wires. The central unshielded conductor is located at the center of the cable. The multiple internal shield conductors are evenly distributed outside the central unshielded conductor, and the long axes of the internal shield conductors are distributed in the radial direction of the cable. The multiple internal unshielded conductors are sequentially arranged between any two adjacent internal shield conductors and are located on the same circumference. The multiple external shield wires are evenly distributed outside a flame retarding taped covering layer. An elastic non-woven fabric taped covering layer and an outer sheath layer are sequentially wrapped on the external shield wires. According to the multicore composite shield cable, since the multiple internal unshielded conductors are arranged between any two adjacent internal shield conductors, filling of gap padding is reduced, and the roundness of the cable is guaranteed; meanwhile, the unshielded conductors are encircled by the shield conductors and the shield wires, so the requirement for shielding the unshielded conductors is met, shield layers and filling materials are reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electric wires and cables, in particular to a multi-core composite shielded cable. Background technique [0002] With the continuous development of electronic technology, the density of electronic equipment or devices installed in a limited space is increasing, which requires the development of electronic equipment or devices in the direction of miniaturization. In some special occasions, the diameter of wires and cables between devices can be reduced as much as possible under the premise of ensuring the performance of wires and cables. However, in the connection occasions that require multi-core cables and electromagnetic shielding functions between core wires, since there is no special multi-core shielded cable for connection, it can only be used by bundling shielded wires one by one into a bundle. As a result, the overall wire diameter of the bundle of wires is too large, and its bending performance a...
