Thus, a detection result specific to the position of the capital is obtained.
- the relationship between the calculation result and the cavity position is as shown in the above graph. Since the connector housings have cavities at approximately 2.5 mm pitch at equal intervals, there is a proportional relationship between the calculated value of X and the position of the cavities. Since the values are almost the same without being affected by the X, it is possible to specify the cavities into which the terminals are inserted by the calculated value of X.

That is, there is no possibility that an AC inspection signal cannot be detected from the Z-axis sensor 40b due to the presence of the Z-axis sensor 40a, and the detection level of the Z-axis sensor 40b may slightly decrease due to the presence of the Z-axis sensor 40a. Even if there is, a certain level value can be detected without fail.
- the detection level of the test signal from the conductive plate is a value inversely proportional to the distance from each wire terminal. Therefore, the reciprocal operation values (1 / Vz1) and (1ZVZ2) are values proportional to the distances from the wire terminals, respectively.

It is desirable to determine that mounting is completed by combining some of the above methods.
- step S7 the inspection control unit 100 detects the connection position where the disconnection piezoelectric wire to which the AC inspection signal is applied is attached, and detects the correct position. Judge whether the insertion into the connector position is detected.
- the AC inspection signal is sequentially applied to each wire, and the cut-off piezoelectric wire housed in the gutter-shaped housing unit that supplies the AC inspection signal by the power supply control unit 170 is connected to the connector 1. Since it can be detected that the cutting piezoelectric wire is attached to 0, it is possible to detect which type of cutting piezoelectric wire is inserted into which position without touching the cutting piezoelectric wire and the terminal.
- the measurement of the terminal insertion position into the connector 10 is performed by measuring a detection signal value in each case when a terminal is inserted into each position of the connector in advance, registering the value as a reference measurement value, and For example, a threshold value for determining the insertion position is obtained and registered together with the reference measurement value.
- the measurement detection result of the X-axis sensor plate and the measurement detection result of the Y-axis sensor plate detected in the inspection mode are compared with the reference measurement value, and the connector position where the terminal is inserted is determined from these measurement detection results. are doing.
- step S7 if the cutting piezoelectric wire for which mounting is instructed has not been inserted into the predetermined connector position, the process proceeds to step S8, and the cause of the failure is identified.
- the power supply timing in the power supply control section 170 is a gutter-shaped storage section in which the cut-off piezoelectric wire to be mounted is stored, and the terminal insertion position is incorrect (by inserting the terminal to another position by mistake). If you do) or When the power supply timing in the power control section 170 is not the gutter-shaped storage section in which the cut-off piezoelectric wire to be mounted is stored, and the terminal insertion position is correct (erroneously insert the terminal to another cut-off piezoelectric wire in the position) If you have done so).
- step S9 the operator is notified of the occurrence of the defect and the cause thereof.
- the occurrence of a defect is indicated by an alarm sound and a blinking display of an erroneous point, for example, a cause is displayed on a display panel (not shown), and a defective point and a correct insertion position are displayed.
- the operator receives the error notification and performs necessary error processing thereafter. For example, if the insertion position is incorrect, the inserted cutting piezoelectric wire is removed, and another new cutting piezoelectric wire is inserted into the connector 10.
- step S7 the inspection control unit 100 determines that the cutting piezoelectric wire is inserted into a predetermined connector position, and that the timing supplied to the cutting piezoelectric wire is also set at the connector position. If the power is supplied to the line, it is determined that the connection has been normally performed, and the process proceeds to step S10, and it is determined whether or not the mounting of all the disconnection piezoelectric wires to the connector 10 has been completed. When the mounting of the disconnecting piezoelectric wires to the connector 10 has been completed, this fact is notified by, for example, an end sound, and the mounting of the terminal to the connector is completed.
- step S10 if all of the cutting piezoelectric wires have not been mounted on the connector 10 yet, the process proceeds to step S15, and the gutter-shaped storage section in which the cutting pressure wires to be mounted are stored next. Identify the position to be stored in connector 10 and proceed to step S3.
- the present embodiment it is only necessary to dispose the sensor plate in the vicinity of the outer wall of each side surface of the connector housing. It is possible to inspect whether or not the terminal is normally attached to the connector in a completely non-contact manner, and it is possible to manufacture an efficient wafer harness. Further, the occurrence of defective products can be reliably suppressed without setting any special inspection process in the process of manufacturing the harness. Furthermore, at the time of inspection, inspection can be performed only by supplying a low-level AC inspection signal that has almost no adverse effect on the human body.
- the inspection signal can be applied from any part of the cutting piezoelectric wire attached to the connector without touching the conductive material, the inspection signal is supplied in exactly the same way even for cutting piezoelectric wires of different lengths can do.
- a means for indicating an insertion position (an insertion position indicating light emitting element) is provided at the bottom.
