no. 1 Embodiment approach

[0028] according to figure 1 The configuration diagram of (a) illustrates the cable of the first embodiment.

[0029] Such as figure 1 As shown in (a), the cable 100 of the first embodiment is equipped with a plurality of inner insulating cores 10, and the inner insulating cores 10 cover the conductor 1 made of twisted wires with the insulator 2. Tensile elastic modulus, and has a lower coefficient of friction than vinyl chloride resin for electric wires.

[0030] Additionally, if figure 1 As shown in (a), the cable 100 of the first embodiment has more than one inner insulating core 10 (a three-core cable is illustrated in the figure) composed of a conductor 1 and an insulator 2, and has a sheath 101. 101 is shaped by filling around inner insulating cores (insulating cores) 10 twisted in required number. The material of the sheath 101 is not particularly limited as long as it is made of resin, but polyvinyl chloride (PVC) is preferably used in view of ease of handling. ...

Embodiment 1

[0048] The cable of the embodiment has: three inner insulating cores composed of a conductor and an insulator; and a sheath formed by twisting the three inner insulating cores. As the insulator, PBT (polybutylene terephthalate), PE (PE for electric wires), and XLPE (PE for electric wires), which are disconnection-proof TPE (thermoplastic elastomer), were used. Insulators with a 2.5% tensile modulus of elasticity of not less than 441 MPa and not more than 800 MPa were used.

Abstract

Provided is a cable (100), which suppresses local bending by increasing the strength of internal insulating cores (10) and reducing friction between the internal insulating cores (10), thereby making it difficult to bend and break wires. The cable (100) has a plurality of inner insulating cores (10), and the inner insulating cores (10) cover a conductor (1) composed of twisted wires with an insulator (2), and the insulator (2) has a vinyl chloride resin High tensile elastic modulus, and has a lower coefficient of friction than vinyl chloride resin for wires.

Description

technical field [0001] The present invention relates to a cable that can be used as a rubber insulated flexible wire and a rubber insulated flexible cable used for power supply and control purposes of home appliances, general chargers, etc. cable. Background technique [0002] Rubber insulated flexible wires and rubber insulated flexible cables (hereinafter simply referred to as cables) used in home appliances, general chargers, and on-board charging of plug-in hybrid vehicles, etc., are generally such as VCTF (vinyl insulated flexible wire), VCT ( Vinyl insulated flexible cables) are widely used because vinyl chloride resins that are inexpensive, easy to process, and have stable electrical characteristics are used as insulators for covering cables. [0003] Conventionally, such cables have used flexible materials in order to satisfy ease of handling. For example, if Figure 4 As shown, the cable 202 used in the hair dryer 200 is wound around the hair dryer main body 201 f...
