  Hereinafter, embodiments will be described with reference to the drawings.

(First embodiment)
FIG. 2 is a block diagram schematically showing the miswiring detection apparatus 6 according to the present embodiment.

  The miswiring detection apparatus 6 according to the present embodiment is used when a plurality of wirings 5 (5-1, 5-2,...) Provided in the device 1 are connected to the connector 2, and detects miswiring. It has a function. The connector 2 is provided with a plurality of pin holes 13 (13-1, 13-2; connection portions) corresponding to the plurality of wires 5. The user connects each wiring 5 to the connector 2 by inserting each of the plurality of wirings 5 into the corresponding pin hole 13.

  On the other hand, as illustrated in FIG. 2, the erroneous wiring detection device 6 includes an input device 9, an output device 10, a comparison unit 8, and a connection position signal generation unit 7.

  The input device 9 is a part that receives an instruction from the user. The input device 9 receives information specifying a pin hole 13 (hereinafter, target pin hole) into which the wiring 5 is to be inserted from the user, generates information specifying the target pin hole 13 as a target signal, and sends it to the comparison unit 8. It has a function to notify. That is, the input device 9 functions as a target signal generation unit.

  When the wiring 5 is inserted into any of the plurality of pin holes 13, the connection position signal generation unit 7 generates a signal for identifying the pin hole 13 into which the wiring 5 is inserted as a connection position signal. 8 has a function of notifying.

  Specifically, the connection position signal generation unit 7 includes a power supply connection unit 11, an amplifier 12, a test power supply wiring 21, and a plurality of test wirings 19 (19-1, 19-2,...). . The plurality of test wirings 19 are provided so as to correspond to the plurality of pin holes 13. The power connection 11 is detachably attached to the connector 2. When the power supply connecting portion 11 is attached to the connector 2, each of the plurality of pin holes 13 is connected to the power supply via the corresponding test wiring 19. Further, the connector 2 is connected to a power source via the test power supply wiring 21. The plurality of test wirings 19 are connected to the comparison unit 8. The amplifier 12 has a function of amplifying signals generated in the plurality of test wirings 19 and supplying the signals to the comparison unit 8 as connection position signals.

  The user grasps the connector 2 with one hand and inserts the wiring 5 into any of the plurality of pin holes 13 using the tool 22 with the other hand. In this case, from the power source, the test power supply wiring 21, the connector 2, the user (human body) holding the connector 2 with one hand, the tool 22 held by the user with the other hand, the wiring 5 (5-2) to be inserted, A current flows through the pin hole 13 (13-2) into which the wiring 5 is inserted and the test wiring 19 (19-2) connected to the pin hole 13 (no current flows in the device 1). The current is amplified by the amplifier 12. A signal indicating whether the amplified current is flowing in any of the plurality of test wirings 19 is notified to the comparison unit 8 as a connection position signal.

  The comparison unit 8 has a function of comparing the target signal and the connection position signal and determining whether or not the pin hole 13 into which the wiring 5 is inserted is the detection target pin hole 13. That is, the comparison unit 8 determines whether the wiring 5 is inserted into the correct pin hole 13 or the wrong pin hole 13. The comparison unit 8 has a function of generating a determination signal indicating the determination result and notifying the output device 10. The comparison unit 8 is realized by, for example, an IC (Integrated Circuit).

  The output device 10 has a function of outputting normal information or miswiring information based on the determination signal. That is, when the wiring 5 is inserted into the correct pin hole 13, the output device 10 outputs normal information indicating that the wiring 5 is correctly inserted. On the other hand, when the wiring 5 is inserted into the wrong pin hole 13, the output device 10 outputs erroneous wiring information indicating that the wiring is incorrect.

  Subsequently, an erroneous wiring detection method according to the present embodiment will be described. FIG. 3 is a flowchart showing an erroneous wiring detection method.

Step S1; Generation of Target Signal First, the user inputs information indicating the target pin hole 13 via the input device 9. The input device 9 generates a target signal based on the input information and supplies the target signal to the comparison unit 8.

Step S2: Insertion of Wiring Next, the user inserts the wiring 5 into any of the plurality of pin holes 13.

Step S3: Generation of connection position signal When the wiring 5 is inserted, the power supply is connected to the test power supply wiring 21, the connector 2, the user's human body, the tool 22, each pin hole 13, the wiring 5, and each test wiring 19. Current flows. As a result, a connection position signal is generated and notified to the comparison unit 8.

Step S4; Determination The comparison unit 8 compares the target signal and the connection position signal, and determines whether or not the pin hole 13 into which the wiring 5 is inserted matches the target pin hole 13. The comparison unit 8 generates a determination signal indicating the determination result and notifies the output device 10 of the determination signal.

Step S5: Output The output device 10 outputs normal information or miswiring information based on the determination signal. That is, when the pin hole 13 into which the wiring 5 is inserted matches the pin hole 13 to be detected, normal information is output. On the other hand, if the pin hole 13 into which the wiring 5 is inserted does not match the pin hole 13 to be detected, incorrect wiring information is output.

  As described above, according to the present embodiment, normal information is output when the wiring 5 is correctly inserted into the pin hole 13 to be detected. On the other hand, when the wiring 5 is inserted into the pin hole 13 that is not a detection target, erroneous wiring information is output. Information is output not only when the wiring 5 is inserted into the correct pin hole 13 but also when the wiring 5 is inserted into the wrong pin hole 13. Therefore, the user can immediately know that the wiring is incorrect.

  In the present embodiment, it is preferable that the voltage of the power source is set so that the current flowing in step S3 is smaller than the current flowing in the wiring 5 during actual operation. Although no current flows through the device 1 (even if it flows), if a large current flows in step S3, a large current may flow through the device 1, and the device 1 may break down. If the current flowing in step S3 is weak, the device 1 is prevented from failing in order to detect erroneous wiring.

(Second Embodiment)
Next, the second embodiment will be described. In the present embodiment, the structures of the input device 9 and the output device 10 are devised. About another point, since the structure similar to 1st Embodiment is employable, detailed description is abbreviate | omitted.

The plurality of light emitting members 14 are configured to be pressed. The user can input information indicating the target pin hole 13 by pressing any one of the plurality of light emitting members 14. As each light emitting member 14, a member (for example, LED) that can emit light in a plurality of colors is preferably used.

  Also, the input / output device outputs normal information by causing the light emitting member 14 corresponding to the target pin hole 13 to emit light in a specific color (for example, blue). On the other hand, the input / output device outputs erroneous wiring information by causing the light emitting member 14 corresponding to the pin hole 13 to be detected to emit light in a color (for example, red) different from the normal information.

  The speaker 15 functions as the output device 10 and outputs normal information or incorrect wiring information by sound.

  According to this embodiment, since the input device 9 and the output device 10 are integrated, the operability for the user can be improved.

  The keyboard modem 16 acquires the determination signal and converts normal information or incorrect wiring information indicated by the determination signal into a character signal.

  The computer 17 is configured to execute a sound reproduction program (for example, Windows Media Player (registered trademark)) and a display program (for example, Excel Visual Basic) stored in a ROM (Read Only Memory) or the like. The computer 17 reproduces the character signal by the speaker 15 by executing the voice reproduction program. Further, the computer 17 displays a character signal on the display 18 by executing a display program. Thereby, normal information or incorrect wiring information is output by the speaker 15 and the display 18.

Then, the order control unit 20 determines whether or not the wiring 5 is correctly inserted into the pin hole 13 (whether or not normal information is output). When the wiring 5 has not been correctly inserted into the pin hole 13, the operations after step S2 are repeated.

Step S7: Generation of a new target signal When the wiring 5 is correctly inserted into the pin hole 13, the order control unit 20 inserts the wiring 5 next from the plurality of pin holes 13 according to a predetermined order. The pin hole 13 to be formed is determined as the next target pin hole 13. The order control unit 20 generates a signal indicating the next target pin hole 13 as a new target signal and supplies it to the comparison unit 8 and the output device 10.

Step S8: Output of information indicating the next processing target When the output device 10 acquires a new target signal, the output device 10 outputs information indicating the pin hole 13 into which the wiring 5 is to be inserted next, and notifies the user. That is, the output device 10 outputs information indicating the next target pin hole 13 after outputting normal information in step S5.

  Thereafter, the user inserts the next wiring 5 in accordance with the output information, and the processes after step S2 are repeated.

  According to this embodiment, the order controller 20 outputs information indicating the pin hole 13 into which the wiring 5 is to be inserted next. Therefore, the user can easily recognize the pin hole 13 into which the next wiring 5 is to be inserted.
