Finally, remove the insertion jig 8 (10 and 1! 1! Tie 150A
After removing the terminal board housing, the terminal board housing can be installed.

Although the adhesive sheet 1-24OA is positioned around one opening to the through hole 210, it will be clear that it could also be positioned around the other opening.

In the above, the insertion of the contact pin 1 (10.1 (10A) into the terminal board 2 (10.20OA) and the placement on the circuit board 3 (10) are performed in separate steps, but this is done in a series of operations. May be executed.

That is, the other terminal board 2 (10B is the circuit board 3 (10)
It is arranged on the side where the terminal board 2 (10B is not attached).
and a fixed step part 220B are formed in the same manner as the terminal board 2 (10). In addition, a locking leg part 230B is also formed in the other terminal board 2 (10B), and a through hole 330B of the circuit board 3 (10) is formed. The other terminal board 2 (10B) is fixed to the circuit board 3 (10) by being inserted into the circuit board 3 (10).

Other terminal Fi2 (10B has terminal board housing 4 (10B)
Another terminal board housing 4 (10A) having the same structure as the terminal board housing 4 is attached.

The other configurations are the same as those shown in FIGS. 1 to 8, so their explanation will be omitted.

In the above, the contact pins are installed in the terminal board by drilling through holes in the pre-molded terminal board and inserting the contact pins into the holes. It will be obvious that this may be done by integrally molding the terminal plate by pouring insulating material after placing the contact pins.

(3) Effects of the Invention As is clear from the above, the present invention provides a method in which a plurality of contact pins are implanted in advance on a terminal board separate from a circuit board, and then the plurality of contact pins are placed on the circuit board together with the terminal board. This has the effect of preventing the multiple contact pins from being damaged when arranging them on the circuit board, and the work of arranging the multiple contact pins on the circuit board can be completed in an extremely short time. This has the effect of significantly reducing costs. Further, the present invention provides a terminal board on which a plurality of contact pins are arranged with respect to a circuit board, and a removable terminal board housing is disposed on the terminal board, and a mating pin is formed on the terminal board housing, for example, to form a mating pin. Since the terminal board housing is specified, it is possible to respond to changes in the mating connector by simply replacing the terminal board housing. In addition, in the present invention, since the contact pins are collectively arranged on the terminal board by gripping the connecting band, the arrangement of the contact pins on the terminal board and the arrangement of the terminal board on the circuit board are performed in a series of steps. It has effects that can be implemented in the work process. Furthermore, the present invention
Since a plurality of contact pins are implanted on the terminal board prior to placement on the circuit board, the positioning of the multiple contact pins in the direction perpendicular to the circuit board can be determined at the time of implantation on the terminal board. This has the effect of making it possible to achieve reliable contact without worrying about contact with a mating connector. In addition, in the present invention, since the plurality of contact pins embedded in the terminal board are attached to the through holes of the circuit board together with the terminal board, each of the plurality of contact pins is held at two points, so that the holding strength is sufficient. It has the effect of ensuring.
