SEARCH DEVICE FOR ELECTRIC WIRE OR CABLE AND METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To certainly distinguish a connected wiring path from other wiring paths when distinguishing and searching for the target wiring path from the wiring paths disposed near the target wiring path. SOLUTION: Plural electric wires or cables 201-20n are laid close to each other. In this search device, a magnetic plate 21a that is a detection means 21 is inserted into a narrow gap formed by the electric wire or cable 201 (or 202-20n) and is wound around the nearly whole periphery of the search target electric wire or cable 201 (or 202-20n). Thereby, with different from a conventional search device detecting only a part of magnetic flux around the electric wire or cable 201 (or 202-20n), the magnetic flux over the nearly whole periphery of the electric wire or cable 201 (or 202-20n) is permeated to minimize influence by the magnetic flux of the other electric wires or cables 202-20n close to the electric wire or cable 201. Accordingly, the target electric wire or cable 201 can be certainly specified from the electric wires or cables 201-20n wired close to each other.
