Abstract

PURPOSE:To enable discrimination of separate line wires by a method wherein a signal for line wire discrimination set for each terminal is transmitted, and a line wire discriminating element receives said signal at the other end of the line wire through a contact element, while the number of the terminal to which the line wire is connected, and others, are displayed automatically. CONSTITUTION:In the state wherein each end part of line wires W to be discriminated is connected to a terminal T of a main body element 1, a line wire discrimination signal set for each terminal is outputted. Each line wire discrimination signal is inputted to a line wire discriminating element 3 through a contact element 2 which is brought into sequential artificial contact, by an operator for line wire discrimination, with the end part opposite to the end part whereat the connection is made to the terminal T through each line wire W. Every time when the line wire discrimination signal is inputted through the contact element 2, the line wire discriminating element 3 retrieves terminal discrimination data corresponding to the inputted line wire discrimination signal, detecting the terminal discrimination data corresponding to said discrimination signal and displaying these data.
