The contact pin 3 of the group 1 is inserted into the through hole 7 of the backboard 2, and the shutter 110 blocks the optical axis of the gate type photomicrosensor 109. During this lowering operation, the fitting groove 103 of the disc body 102 of the output shaft 101a of the rotary actuator 101
The roller 84 a fitted to the guide rail 99 is disengaged from the fitting groove 103 and fitted to the guide rail 99. The pressure cylinder 94 is generated by a signal from the gate type photomicrosensor 109.
Is activated, the piston rod 96a descends and hits the upper surface of the holding block 80. The pressure is applied to the press-fitting portion of the contact pin 3 into the through hole 7 of the backboard 2. When it is confirmed that the shutter 110 has passed through the optical axis of the gate-type photomicrosensor 109 and is normally press-fitted when the press-fit bottom dead center is reached, the piston rod 96a of the pressurizing cylinder 94 rises and the holding member 97 rises. Thus, the press-fitting head structure B is lifted. At this time, the contact pin group 1 is press-fitted and held on the backboard 2 and is removed from the pressing portion 91 of the leaf spring member 90.

[0047]

Since the press-fitting head structure B is relaxed by the weight of the weight 108, the tip of the pin is inserted into the through hole 7 due to bending of the contact pin 3 and displacement of the contact pin 3 when descending. Even when the back board 2 collides with the back board 2 as shown in FIG. 21, the contact pin group 1 and the back board 2 are not damaged.

[0048]

Further, at the bottom dead center of the holding cylinder 96, whether or not the pin tip is inserted into the through hole 7 is confirmed by the gate-type photomicrosensor 109, so that a great force is not applied in an abnormal condition. There is.

[0049]

When the pin tip of the contact pin 3 is not properly inserted into the through hole 7 and the pin tip collides with the backboard 2, the shutter 110 reaches a position where it blocks the optical axis of the gate type photomicrosensor 109. Since it does not, it can be judged to be abnormal.

[0050]

The shape of the press-fitting portion 5 of the contact pin 3 is not limited to the U-shaped cross section, and it is obvious that the invention is applicable to all press-fit types. Also,
In the above-described embodiment, the supply to the press-fitting of one type of contact pin group 1 has been described, but even if the number of contact pin groups 1 becomes several due to the difference in the number of pins, it is possible to easily cope with it by adding the work supply unit.

[0051]
