Embodiment Construction

[0022] Embodiments of the present invention will be described below with reference to the drawings.

[0023] figure 1 It is a cross-sectional view showing the electric wire of this embodiment.

[0024] Such as figure 1 As shown, the electric wire 1 is constituted by providing an insulating layer 3 on the outer periphery of a central conductor 2 .

[0025] In the electric wire 1 of the present embodiment, the central conductor 2 is constituted by winding a plurality of metal wires 5 helically around a tensile fiber 4 .

[0026] Since the tensile fiber 4 is provided, the tensile fiber 4 bears the tension received by the electric wire 1, and the disconnection of the metal wire 5 can be suppressed. In particular, when the electric wire 1 is sewn into a cloth-like material or the like, since the electric wire 1 is repeatedly bent with a small radius of curvature, the wire 5 of the metal wire 5 is likely to be broken. With this structure, the tensile load when the electric wire ...

Abstract

An electric wire includes a center conductor, and an insulation layer formed on an outer periphery of the center conductor. The center conductor includes a high tensile-strength fiber and a plurality of metal strands wound around the high tensile-strength fiber.

Description

technical field [0001] The present invention relates to wires, wire harnesses, circuits, cloth, clothes and sheets. Background technique [0002] In recent years, in the medical field, systems capable of constantly monitoring a patient's physical condition and actions have rapidly spread. As such a system, there is known a structure in which a circuit is incorporated in clothes or bed sheets. [0003] As a conventional circuit incorporated into clothes or sheets, a circuit using conductive fibers or metal fibers for wiring is known. [0004] In addition, there is Patent Document 1 as prior art document information related to the present application. [0005] Patent Document 1: Japanese Patent Laid-Open No. 2010-133791 [0006] However, when conductive fibers or metal fibers are used for wiring, corrosion tends to occur in an environment constantly exposed to air or moisture, and the resulting deterioration of electrical characteristics becomes a problem. [0007] Therefo...
