Abstract

A cable with a wire disconnection detection function includes a detecting wire including a conductor formed by twisting a plurality of strands, and a detected wire including a conductor formed by twisting a plurality of the strands. A twist pitch of the conductor of the detecting wire is longer than that of the conductor of the detected wire.

Claims (9)

1 . A cable with a wire disconnection detection function, comprising:

a detecting wire comprising a conductor formed by twisting a plurality of strands; and

a detected wire comprising a conductor formed by twisting a plurality of the strands,

wherein a twist pitch of the conductor of the detecting wire is longer than that of the conductor of the detected wire.

2 . The cable according to claim 1 , comprising:

a plurality of ones of the detected wire being spirally wounded along an outer periphery of the detecting wire.

3 . The cable according to claim 1 , wherein the number of strands used for the conductor of the detecting wire is less than the number of strands used for the conductor of the detected wire.

4 . The cable according to claim 1 , comprising a plurality of ones of the detecting wires each comprising a conductor with a different twist pitch.

5 . The cable according to claim 1 , wherein the twist pitch of the conductor of the detecting wire is 1.6 times to 5 times longer than that of the conductor of the detected wire.
