[0002]

2. Description of the Related Art As a testing device for testing the continuity of a cable, a plurality of testing devices have been known so far.

This test apparatus includes, for example, a simple type test apparatus for conducting a continuity test of a specific cable and a test apparatus for conducting a continuity test of a plurality of different cables. In the former type of test device, it is necessary to provide a test device for each different type of cable.

As a test device for testing whether or not the cable is broken, there is, for example, a resistance measuring machine such as a tester. Further, in the latter type of test device, in a test of a plurality of cables in a factory or the like, a cable for conducting a continuity test is connected to a connector.

For example, since an automatic control device such as a robot has a lot of exchanges of electric signals, a cable having many core wires in one cable is used. When testing whether there is a break in this multi-core cable, connect the connector at the plug-type connector attached to the end of the cable and use a tester etc. for each pin of each connector. A continuity test was conducted.

Therefore, in the latter type of test apparatus, it can be seen that there is no break in the cable when the cable is conducting, and there is a break in the cable when the cable is non-conducting.

On the other hand, in the latter continuity test device, although the cable continuity test can be performed by a tester or the like for each core wire, it is not possible to conduct the continuity test of multi-core cables at the same time, and the type is frequently used. It is necessary to conduct the continuity test of different cables. It is possible to manage the continuity test of multi-core cables that require instantaneous continuity tests such as various cables used in automatic control devices such as robots. I couldn't do that, and my labor was heavy.

Further, in the latter continuity testing device, it was extremely difficult to bring the electrode rod of the tester into contact only with a certain number of pins without touching other pins because the pins approach each other in the connector section.

Further, in the continuity test apparatus up to now, the welding result of the multi-core cable wiring cannot be managed and monitored for a long time by rapidly processing the test result and displaying it as display information. It was

Therefore, an object of the present invention is to enable multi-core cables of different types to be instantaneously subjected to a continuity test, and to promptly perform signal processing on the test result and display it as display information, so that a robot or the like can be tested. It is to manage various cables used for automatic control devices for a long time.
