要し、極めて非能率的であり、また作業性も悪い
ものである。 Conventionally, to check for shorts or breaks in multipolar cables or bundled wires, a method has been adopted in which an AC or DC signal is applied to each cable or bundled wire and checked at both ends. However, since this type of checking method requires checking each time, it takes time proportional to the number of cables or bundled wires, and is extremely inefficient and has poor workability.
本発明はこのような従来の欠点を解消したもの

When current is supplied from , photocouplers 7 to 12
When the light emitting diodes 13 to 18 are turned ON, all light emitting diodes 13 to 18 light up, confirming that there is no abnormality.

表示が行なわれる。 If cables 6a and 6b are short-circuited and terminals 19 and 20 are shorted, no current will flow through photocoupler 10, and therefore light-emitting diode 16 will not light up. This indicates that the cables 6a and 6b are being shot. In addition, when the cables 6c and 6d are connected in reverse, that is, when the cable 6c is connected between the terminals 21 and 27 and the cable 6d is connected between the terminals 22 and 26, a reverse voltage is applied to the light emitting diode 11a of the photocoupler 11, Therefore, all photocouplers do not turn on, and all light emitting diodes do not light up, so the incorrect wiring is displayed. Furthermore, even if one or more of the cables 6a to 6e are disconnected, all the light emitting diodes will not light up, and this will be displayed.

表示素子であつてもよい。 In the above embodiment, the case where there are five cables has been explained, but even if there are more or fewer cables, it is possible to check them all at once using the same connection relationship. The same applies not only to cables but also to bundled wires. Further, although a light emitting diode is used as a display element, other display elements such as a lamp may be used instead.
