Description

  The present invention relates to a manufacturing method and a manufacturing apparatus of a twisted wire (twisted pair wire) formed by twisting two electric wires.

  A twisted wire is an electric wire that can suppress generation of electromagnetic waves or absorb electromagnetic waves, and is manufactured by twisting two electric wires together. In FIG. 3, the twisted wire manufacturing apparatus 1 includes a first end side electric wire fixing member 2 and a second end side rotating member 3. In the twisted wire manufacturing apparatus 1 having such a configuration, a pair of electric wires 5 and 5 that are measured to a predetermined length and provided with terminals 4 at both terminals in advance are set at predetermined intervals.

  The one end side electric wire fixing member 2 is configured so that one end 6 of the pair of electric wires 5 and 5 can be held in an immobile state. Moreover, the other end side rotation member 3 is comprised so that the other end 7 of a pair of electric wires 5 and 5 can be rotatably fixed. The other end side rotating member 3 has the other end side rotating plate 8 that is rotatable while maintaining the electric wire interval, and a rotating mechanism 9 that rotatably supports the other end side rotating plate 8.

  In the above configuration, when twisting is performed by rotating the other end side rotating member 3 from the state of FIG. 3A, a twisted wire 10 as shown in FIG. 3B is manufactured.

In addition, a terminal processing method as shown in FIG. 4 is also known as a conventional method for twisted wire. In FIG. 4, when a twisted wire (twisted electric wire) 11 is manufactured using a twister that is untwisted, both ends of the manufactured twisted wire 11 are untwisted, and the terminal 13 is crimped to the untwisted terminal 12. The terminal processing of the twisted wire 11 is completed.
