[0002] The cable looks like a rope and is usually made up of multiple groups of twisted wires. Each group of wires is insulated from each other and often twisted around a central structure and covered with a highly insulating covering.

[0003] Cables usually include round cables and flat cables. Compared with round cables, flat cables have a more special structure. When the number of core wires is exactly the same, the bending amplitude of flat cables is larger, which can avoid breakage due to frequent bending. In addition, due to the advantage of small wiring space, flat cables are widely used in civilian electrical appliances such as telephones and tape recorders, computers and instruments.

[0004] Currently, the conductors of flat cables on the market mostly adopt a twisted structure, and their sheaths are often extruded with talcum powder to facilitate peeling and processing. This method not only makes it difficult to peel the insulation during processing, but also the over-powdering of the sheath can easily cause environmental problems and unstable peeling uniformity. Utility Model Content

[0005] To this end, the technical problem to be solved by the utility model is to overcome the problem that the conductor of the flat cable in the prior art mostly adopts a twisted structure, and its sheath is mostly processed by talcum powder when it is extruded to facilitate peeling and processing.

[0011] In one embodiment of the present invention, the cross section of the outer sheath is in the shape of an oblong hole, and two side surfaces of the outer sheath in the thickness direction are in a wavy shape to form a plurality of the grooves.

[0012] In one embodiment of the present invention, the wire cores each include a conductor, the conductor is coated with an insulating layer, and the filling oil is filled between the insulating layer and the outer sheath.

[0013] In one embodiment of the present invention, the conductor comprises a plurality of copper wires arranged in parallel, and the plurality of copper wires are in close contact with each other to form the cylindrical conductor.

[0014] In an embodiment of the present invention, the insulating layer is made of polyvinyl chloride.

[0015] In one embodiment of the utility model, the insulating layer is covered with an inner protective layer.

[0016] In an embodiment of the present invention, the outer sheath is made of modified polyvinyl chloride easy-to-tear material.

At the same time, after the outer sheath 1 is peeled, the exposed filling oil 3 will evaporate after a period of time, which has better environmental protection effect and performance than using talcum powder.

[0031] Furthermore, the cross section of the outer sheath 1 is flat, and the plurality of wire cores 2 are arranged side by side along the width direction of the outer sheath 1, and the adjacent wire cores 2 are in close contact with each other and have a gap with the outer sheath 1, and the gap is provided with filling oil 3.

The cable is flat as a whole, and has multiple symmetrical arc parts on the outer surface of the cable, which can improve the compression resistance of the entire cable to a certain extent.

[0035] Furthermore, each wire core 2 includes a conductor 21 , the conductor 21 is coated with an insulating layer 22 , and the filling oil 3 is filled between the insulating layer 22 and the outer sheath 1 .

[0036] Furthermore, the conductor 21 includes a plurality of parallel copper wires, which are closely contacted to form a cylindrical conductor 21.
