Abstract
The invention discloses an open circuit/short circuit detector of a signal wire and aims to provide an apparatus which is convenient to detect closed-circuit, open-circuit and short-circuit states of the signal wire. The detector comprises a power supply 5, a current limiter 4 and an indicator 3 which are sequentially connected between corresponding splicing points of two sockets. Two plugs at the two ends of the signal wire are inserted into the socket 1a and the socket 1b respectively, and the closed-circuit, open-circuit and short-circuit states of the signal wire are judged by the indicator 3. When a certain core wire in the signal wire is conducted, the indicator 3 corresponding to the core wire is lightened; if the certain core wire is not conducted, the indicator 3 corresponding tothe core wire is not lightened; and if short circuit occurs between certain two adjacent core wires, the corresponding indicator 3' between the two adjacent core wires is lightened. When various sockets are connected in parallel, the detector is also a plug converter.
