Combined multi-core cable

Abstract

The invention discloses a combined type multi-core cable. The cable is formed by plugging a plurality of square cables. The square cable is an independent wire body formed by wrapping an insulator ona metal conductor. The square cable is an equilateral square. For only one cable, oval concave parts and oval convex parts are respectively and symmetrically formed by a diagonal line of the square; when the cable is combined with the other independent square cable, the oval concave part and the oval convex part are inserted with each other; the convex part and the concave part are made of the same insulating plastic; the hardness of the convex part is lower than that of the concave part, the convex part and the concave part are formed into a whole through double-machine co-extrusion during manufacturing and extrusion, so that the oval convex part can be locked by the hard oval concave part during insertion, and by means of the mode that the convex part and the concave part are connected in an inserted mode, high locking force is achieved, and the disassembly and assembly convenience is high.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to a combined multi-core cable. Background technique [0002] At present, the traditional cables are all round, that is, extruding a layer of insulating layer on the outside of a single heterogeneous cable to make an insulated cable, and then according to the needs, different numbers of insulated cables are twisted, filled with mesh tape, and then extruded with a layer of sheath. sets of off-the-shelf cables, in [0003] During the twisting process, the cables are often broken down due to mutual extrusion of the insulation layers, resulting in the scrapping of the cables or stripping of the insulation layers [0004] Rework. In addition, the cable should be kept round and filled with a large number of torn mesh belts, adding a layer of sheath with a considerable thickness will cause the cable to be bulky and heavy; [0005] For this reason, researching a combined square cable with...
