Embodiment Construction

[0024] Hereinafter, examples of embodiments of the multi-core cable and its manufacturing method according to the present invention will be described with reference to the drawings.

[0025] Such as figure 1 As shown, the multi-core cable 10 according to this embodiment has an even number of coaxial wires 11 for high-speed transmission and a plurality of insulated wires 21 for power supply or low-speed signals inside a sheath 30 as the outermost layer.

[0026] In order to be suitable for differential transmission, the multi-core cable 10 accommodates two coaxial wires 11 as a set. As the coaxial wires 11 in the multi-core cable 10 of this example, four sets of coaxial wires 11A, 11B, coaxial wires 11C, 11D, coaxial wires 11E, 11F, and coaxial wires 11G, 11H are accommodated. . Each set of coaxial electric wires 11 (for example, 11A and 11B) may be closely arranged, or all the coaxial electric wires 11 may be arranged at equal intervals. In addition, insulated wires 21A, 21...

Abstract

The present invention provides a multi-core cable having a plurality of insulated wires and a plurality of coaxial wires capable of suppressing disconnection in the cable and a method for manufacturing the same. The multi-core cable (10) has: insulated wires (21A, 21B) arranged at the center of the cross section of the cable; insulated wires (21E, 21F) arranged close to the insulated wires (21A, 21B); The insulated wires (21A, 21B) are thin; an even number of coaxial wires (11), they are arranged on the same circumference around the insulated wires (21A, 21B) and the insulated wires (21E, 21F); and tensile fibers (31 ), which are disposed in gaps between the insulated wires (21A, 21B) and the insulated wires (21E, 21F) and the coaxial wire (11).

Description

technical field [0001] The invention relates to a multi-core cable with a plurality of insulated wires and a plurality of coaxial wires and a manufacturing method thereof. Background technique [0002] A configuration is known in which, as a multi-core cable formed using a coaxial electric wire, a tension member is provided at the center of the cable, and a coaxial cable or a coaxial cable unit is disposed around it (for example, refer to Patent Literature 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2007-169687 [0004] In recent years, the high-speed transmission of peripheral equipment cables used to connect peripheral equipment to personal computers has progressed, and the use of frequency bands has been expanded to several GHz bands. In addition, as a transmission method of digital signals such as video, differential signal transmission has become the mainstream. In the cable described above, it is conceivable to use multiple coaxial wires to differe...
