<p>PROBLEM TO BE SOLVED: To provide a simple and inexpensive contact detection device capable of detecting surely a contact between cable cores in a cable laying field in a station or the like. SOLUTION: This device is equipped with connector terminals for connecting a connector installed on one end of a cable to be inspected, voltage applying wires L1-L27 connected to each core of the cable to be inspected through each connector terminal with interposed resistance elements respectively, shift resistors 3A-3D and buffers 5A-5D for supplying the voltage applying wires with a voltage successively, a comparator for comparing the voltages on both ends of each resistance element of each voltage applying wire L1-L27, and emitting a contact signal when the difference between the voltages on both ends is generated, and an LED lamp and a buzzer operated by the contact signal.</p> |
