DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a super-flex resistant conductor useful as a conductor of a moving electric wire used for extending or leading out of a moving part of an electrical device, for example.

Typical methods for improving the bending resistance (in a broad sense, including twisting, tensile strength, etc.) of conductors for electric wires are to reduce the diameter of the stranded wires or to reduce the twisting pitch of the strands. It is. A horizontally wound conductor has been put into practical use as an extreme measure to reduce the twisting pitch.

However, this prior art horizontally wound conductor could only be manufactured in a small size.

An object of the present invention is to provide a horizontally wound ultra-flexible conductor of relatively large size.

In other words, the gist of the present invention is that 2 to 4 strands of stranded wire, which are made by twisting multiple conductor strands in advance, are arranged on a flexible center string with tensile strength and then tightly wound horizontally. The point is that one or more layers are provided.

Specifically, for the above stranded wire, for example, the diameter
3 to 7 tin-plated annealed copper wires of about 0.10 to 0.18 mm
A total of about 100 liters is used. The reason for horizontally winding the stranded wire in two to four strands is to take into consideration the manufacturing workability and bending resistance of the conductor. When horizontally winding stranded wire, it is more efficient to wind multiple wires side by side than to wind one wire at a time.

However, as confirmed by the inventors of the present invention, there is a problem in that the flexibility of the conductor deteriorates when more than four strips are wound side by side. Note that if the number of wires to be arranged increases, the winding pitch will increase and the bending resistance of the conductor will decrease. Therefore, when trying to obtain a relatively large conductor, multiple horizontally wound layers are used. It is better to

In the present invention, this stranded wire 2 is made of a central string 3 that is flexible and has relatively mechanical strength, that is, has a predetermined tensile strength (e.g., twisted threads of synthetic fibers such as polyester or nylon). It has two layers arranged on top of each other and tightly wound horizontally.
