Abstract

PURPOSE:To elevate the disconnection detection sensitivity with a detection coil in which several ways of a coil is looped across two points provided at a position circumferentially varied on a hollow cylindrical bobbin in such a manner as to be separated axially. CONSTITUTION:Support sets 2 and 3 comprising two struts 2a and 2b and 3a and 3b provided at a position circumferentially varied are provided on the circumferential surface of a hollow cylindrical bobbin 1 in such a manner as to be separated axially. In the support set 2, a coil 4 is looped in specified turns across the inner strut 2b and the outer strut 2a and in the support set 3, a coil 5 is looped across the innner strut 3a and the strut 3b. The coils 4 and 5 form a magnetic field in the radial direction of the bobbin, where the magnetic field of the coil 4 is N in polarity while that of the coil 5 is S. Therefore, an eddy current orients to the radial direction of the bobbin 1, namely, the direction of the twisted wire axis thereby increasing the disconnection detection sensitivity of disconnection.
