Title:
WIRING PATH PROBING DEVICE
Document Type and Number:
Japanese Patent JP3299466
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a wiring path probing device which is comprised of a transmitter that supplies a current having a predetermined frequency to a wiring path and a receiver for probing a target wiring path by detecting a magnetic flux generated on the wiring path by virtue of the current supplied by the transmitter.
SOLUTION: A receiver 1 detects a magnetic flux generated on a wiring path by virtue of current supplied by a transmitter. A probing face 2b to be opposed to the wiring path is provided to one end portion 2a in the longitudinal direction of a body 2. Probing coils L1, L2 which are inclined at roughly the same angle in the different directions with respect to the probing face 2b are disposed in the vicinity of the probing face 2b in the inner section of the body 2. In response to switching operation of a switch S2, a vector sum or a vector difference of magnetic flux vectors in the coil axis directions which are detected by the coils L1, L2 is obtained so that the magnetic flux which is parallel or perpendicular to the probing face 2b is detected.
