Abstract

(57) [Summary] [Object] The present invention relates to a multi-core horizontal winding excellent in flexibility and high flexibility, and provides a multi-core horizontal winding that is easy to manufacture and inexpensive. [Structure] First, a plurality of insulating core wires 5 in which a conductor 3 made of one or a plurality of wires is covered with an insulator 4 or an insulating layer 7 is used as a core yarn 2 made of one or a plurality of wires. It is a multi-core transverse winding characterized in that it is wound in parallel and wound in parallel without being double-lapped around it, and a sheath 6 is applied on it. Secondly, an insulating horizontal winding unit in which a plurality of insulating core wires 5 in which one or more conductors 3 are covered with an insulator 4 or an insulating layer 7 is wound around the second central yarn 2. The multicore transverse winding is characterized in that the cores 9 are wound in parallel around the first central yarn 2 without being doubled and wound, and the sheath 6 is applied thereon.

[Industrial applications]

 The present invention relates to a multi-core horizontal winding excellent in flexibility and high flexibility, and provides a multi-core horizontal winding that is easy to manufacture and inexpensive.

[0002]

[Prior art]

Conventional multi-fiber cable 10 ', the conductor 3''after twisting a bundle of the sheath 6''plurality of insulated wires 5 having been subjected to' or insulated wires pair 11 insulator 4 was subjected to structure and {3 (b) see}, a plurality of insulated wires 5 'were integrated by means of heat fusion or the like, the sheath 6 it onto a round meta' structure {see FIG. 3 (b) subjected to } Etc. However, such a product cannot be used for general household electric appliances such as telephones and movable parts such as robots because of problems in flexibility and bendability. The advent of a multicore cable having excellent properties has been demanded.

[0003]

[Means for Solving the Problems]

In order to solve these drawbacks and technical demands, the present invention has been made as a result of extensive studies and was made for the purpose of providing a multi-core transverse winding 1 excellent in flexibility and high flexibility. In the first place, the conductor 3 made of one or a plurality of wires is covered with the insulator 4 or the insulating layer 7, and the insulating core wire 5 made of a plurality of wires is used as the central yarn made of one or a plurality of wires. It is a multi-core horizontal winding characterized in that it is wound in parallel around two wires in parallel without being overlapped with each other, and a sheath 6 is applied thereon. Secondly, an insulating horizontal winding unit in which a plurality of insulating core wires 5 each consisting of one or a plurality of conductors 3 covered with an insulator 4 or an insulating layer 7 is wound around the second central yarn 2. 9, with can wound Te parallel Namirabe without overlapping double around the first center yarn 2, Takokoroyoko winding having a super flex performance, characterized in that subjected to the sheath 6 on the Is.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Fig. 1 (a) shows the multi-core horizontal winding of the present invention.12 is a perspective view of the first embodiment of the present invention, showing an insulating core wire composed of a plurality of conductors 3 covered with an insulator 4 such as plastic or an insulating layer 7. 5 A multi-core transverse winding having a structure in which the first core yarn 2 is wound in parallel around the first central yarn 2 without being doubled, and a sheath 6 is provided on the winding.1Is. As the insulating layer 7, for example, the conductor 3 is baked with urethane paint, polyester paint, or the like. Figure 1 (b) shows the multi-core horizontal winding of the present invention.12 is a cross-sectional view of the second embodiment of the present invention in which a plurality of conductors 3 are stranded. FIG. 1C shows the multi-core horizontal winding of the present invention.1Fig. 3 is a cross-sectional view of a third embodiment of the present invention, in which a conductor 3 is provided with an insulating layer 7 such as urethane paint or polyester paint, and is a plurality of baked insulating core wires.5Insulated horizontal winding unit in which the wire is wound around the second center yarn 29A multi-core transverse winding having a structure in which the first core yarn 2 is wound in parallel around the first central yarn 2 without being doubled, and the sheath 6 is applied on the winding.1Is. Multi-core horizontal winding with such a structure 1 By doing so, it is possible to obtain a multi-core horizontal winding having an extremely high bending performance. Multi-core horizontal winding of the present invention1Because of the above structure, the area of the part that receives stress when the multi-core horizontal winding is bent is larger than that of the straight wire, and less stress is received per unit area (see Fig. 2). Further, since the tensile strength and the like are strengthened by the central yarn, a multi-core horizontal winding excellent in flexibility and high flexibility can be obtained.

Up to now, the insulator 4 and the insulating layer 7 have been described as representative examples, but other insulators may be used. Further, it goes without saying that various modifications are included within the scope of the present invention in terms of design such as shielding.
