In contrast, among the first connectors 35A to 35C, one of the first to sixth pins 25a to 25f of each of the fourth connectors 24A to 24C is used to detect the erroneous insertion of the connector.

In the fourth connector 24A on the left side in Fig. 4, the first and second pins 25a and 25b (fourth detection pin) are used to detect the erroneous insertion of the connector, and the third to sixth pins 25c to 25f is used for DUT testing. In the fourth connector 24A on the left side, the second pin 25b is connected to the seventh pin 25g via the detection line pattern 22 formed on the second substrate 21, and the eighth pin 25h is connected via the detection line pattern 22.

As shown in FIG. 5, the first pin 25a of the fourth connector 24A on the left side and the eighth pin 25h of the fourth connector 24C on the right side are connected to the erroneous insertion detecting device 5 provided in the tester 2.

The erroneous insertion detecting device 5 detects that the second connectors 43A to 43C are erroneously inserted into the first connectors 35A to 35C, and has the input unit 6 and the determination unit 7. Further, as a result, the erroneous insertion detecting device 5 can detect that the third connectors 45A to 45C are erroneously inserted into the fourth connectors 24A to 24C.

The input unit 6 is connected to the first pin 25a of the fourth connector 24A on the left side, and can input a detection signal for detecting the erroneous insertion of the connector to the first pin 25a. Further, a confirmation signal for confirming whether or not the high jig 15 is attached to the test head main body 11 can be used as the detection signal, and the determination unit 7 is connected to the eighth pin 25h of the fourth connector 24C on the right side to confirm the input. Whether or not the detection signal input from the unit 6 is output from the eighth pin 25h. When the output of the detection signal is confirmed, the determination unit 7 allows the power supply for the DUT test to be supplied to the power supply unit 4 of the tester 2. On the other hand, when the output of the detection signal is not confirmed, the determination unit 7 does not allow the supply of the test power to the power supply unit 4.

Second, explain the role.

Fig. 6 is a view showing a detection route of erroneous insertion in the embodiment, Fig. 7 is a view showing an example of a connection relationship when the connector is erroneously inserted in the embodiment, and Fig. 8 is a view showing different specifications in the embodiment. An example diagram when the cable is incorrectly connected.

First, in the example shown in Fig. 4, the case where all the connectors are correctly inserted will be described with reference to Fig. 6.

As shown in Fig. 6, when the second connectors 43A to 43C are inserted into the first connectors 35A to 35C, respectively, and the third connectors 45A to 45C are inserted into the fourth connectors 24A to 24C, respectively, the fourth connector 24A on the left side is inserted. Between the first pin 25a and the eighth pin 25h of the fourth connector 24C on the right side, an erroneous insertion detecting route 50 in which all the detecting pins are connected in series is formed. In this state, when the input unit 6 of the erroneous insertion detecting device 5 inputs the detection signal, the detection signal is output to the determination unit 7 via the erroneous insertion detection route 50, and the determination unit 7 does not allow the test power supply to the power supply unit 4. Supply. Further, a plurality of erroneous insertion detection routes may be formed, and in order to individually detect erroneous insertion of each connector, an erroneous insertion detection route may be formed for each connector.

On the other hand, for example, as shown in FIG. 7, the second connector 43A of the first connector 35A to be inserted into the left side is erroneously inserted into the first connector 35B at the center, and the first connector 35B to be inserted into the center. When the connector 43B is erroneously inserted into the first connector 35A on the left side, the first pin 36a and the second pin 36b of the first connector 35B in the center are not connected to each other, and the erroneous insertion detecting route 50 is not formed.

Further, for example, as shown in Fig. 8, when the cable 40' not having the detected lead wire 42 is misused as the center cable, between the seventh pin 46g and the eighth pin 46h of the center second connector 43B The erroneous insertion detection route 50 is blocked.

In the case shown in FIGS. 7 and 8, even if the detection signal is input to the input unit 6 of the erroneous insertion detecting device 5, since the detection signal is not output to the determination unit 7, the determination unit 7 does not allow the power supply unit 4. Test the supply of power.

As described above, in the present embodiment, one of the plurality of pins 36a to 36h having the first connectors 35A to 35C is electrically connected to each other. because After the connector is inserted, it is confirmed that the detection signal is input from one of the detection pins, and the detection signal is output by the other detection pin, thereby confirming the connector system at the insertion point before supplying the test power source. The connector that should have been inserted.

Further, in the present embodiment, one of the plurality of pins 46a to 46h of the third connectors 45A to 45C is electrically connected to each other. Therefore, after the connector is inserted, it is confirmed that the detection signal is input from one of the detection pins, and the detection signal is output by the other detection pin, thereby confirming that the cable of the correct specification is connected.

The embodiments described above are intended to facilitate the understanding of the present invention and are not intended to limit the invention. Therefore, each element disclosed in the above embodiments is intended to include all design changes and equivalents belonging to the technical scope of the present invention.

For example, the third and fourth connectors 45 and 24 may be omitted, and the lower end of the cable 40 may be directly connected to the wiring pattern on the second substrate 21 by soldering or the like.

Further, in the fourth connector 24 of the operation characteristic plate 20, a pair of detection pins electrically connected to each other may be provided, and the third connector 45 may be detected to be erroneously inserted into the fourth connector 24. For example, in the example shown in FIG. 9, the first and second pins 25a and 25b (first detecting pin) of the fourth connector 24 are used to detect that the third connector 45 is mistakenly inserted into the fourth connection. 24. As shown in the drawing, the first pin 25a and the second pin 25b of the fourth connector 24 are electrically connected to each other via the detection line 22 formed on the second substrate 21 via the operating characteristic plate 20. Further, in this case, the fourth connector 24 in the present embodiment corresponds to an example of the first connector of the present invention, and the third connector 45 in the present embodiment corresponds to an example of the second connector of the present invention. Further, although not specifically shown, it is possible to more reliably prevent erroneous insertion of the connector by changing the position of the pin detected in each connector. Moreover, in this case, the first and second connectors 35 and 43 may not be used, and the upper end of the cable 40 may be directly connected to the line pattern on the first substrate 31 by soldering or the like.
