On the other hand, if the connectors 5 and 6 are not normally fitted (that is, in the half-fitted state), the connectors 5 and 6 in the half-fitted state are partially connected in the inspection current path 10. Not in a state. Specifically, the other end 11b of the first current path 11 and the one end 13a of the third current path 13 are separated, and the other end 12b of the second current path 12 and the other end 13b of the third current path 13 are separated.

Specifically, in step S <b> 2, for example, the user activates predetermined software installed in advance on the operation display device 50 as an example. Then, an examination start button is displayed on the display of the operation display device 50. When the user selects and determines the inspection start button, the inspection instruction signal Sa is transmitted from the inspection instruction side BT module 51 to the inspection object side BT module 46.

  Next, in step S3, the inspection target side BT module 46 that has received the inspection instruction signal Sa instructs the PIC microcomputer 45 to perform a continuity inspection on each electrical connection device 4. In step S <b> 3, the PIC microcomputer 45 performs a continuity test on each electrical connection device 4. Specifically, the PIC microcomputer 45 applies a minute voltage to each first terminal 45a and each second terminal 45b, and resistance between the first terminal 45a and each second terminal 45b based on a current value flowing therebetween. Calculate the value. If the resistance value is less than the predetermined value, the PIC microcomputer 45 determines that the electrical connection device 4 is normally fitted. On the other hand, if the resistance value is equal to or greater than the predetermined value, the PIC microcomputer 45 determines that the electrical connection device 4 is not normally fitted, that is, is in a half-fitted state.

  Next, in step S <b> 4, the operation display device 50 is notified of the result of the continuity test performed on each electrical connection device 4. Specifically, the inspection result of each electrical connection device 4 inspected by the PIC microcomputer 45 is notified from the inspection object side BT module 46 to the inspection instruction side BT module 51 using the Bluetooth communication method.

  Finally, in step S5, the inspection result is displayed on the operation display device 50. Specifically, the inspection result (continuity test OK or continuity test NG) of each electrical connection device 4 is displayed on the display of the operation display device 50.

[effect]

When the inspection object side BT module 46 receives the inspection instruction signal Sa, the PIC microcomputer 45 receives the instruction from the inspection object side BT module 46 and performs the continuity inspection of the continuity inspection object 2. The test result of the continuity test is notified from the test target side BT module 46 to the operation display device 50 by wireless communication using the Bluetooth communication method. The operation display device 50 displays the inspection result.
