The contact portion 110 of the contact pin 100 is press-fitted into the through hole 310 of the contact pin 100 and arranged to protrude into the connector receiving recess 531 of the connector housing 500 . If the insertion jig 600 is removed, the state shown in the lower half of FIG. 5 will be obtained.

Next, as shown in FIG. 5, the terminal board housing 400 is moved from the top in the direction of arrow C to be attached to the terminal board 200 placed on the circuit board 300. That is, the contact portion 1 of the contact pin 100
20 is inserted into the through hole 410, and the fixing latch portion 434 is fitted to the fixing step portion 220 of the terminal plate 200, resulting in the state shown in FIG. 2, and the assembly process is completed.

Furthermore, the terminal board housing 400 can be easily removed from the terminal board 200 by inserting the removal jig 700 shown on the upper side of FIG. 2 into the connector receiving recess 431. That is, the terminal board housing 400 can be removed from the terminal board 200 by expanding the fixing latch part 434 outward with the removal jig 700 and releasing the engagement of the protrusion 435 with the fixing step part 220. . Therefore, different terminal plate housings 400 of the fitting key portion 432 can be easily replaced depending on the mating connector, and various combinations are possible.

In the above description, the contact pin 100 is inserted and fixed into the through hole 210 of the terminal board 200 by the press-fit protrusion 141 of the terminal board insertion part 140, but in this case, a relatively large force is applied when the contact pin 100 is attached to the terminal board 200. Therefore, there is a risk that the contact pin 100 or the terminal board 200 may be damaged. Therefore, the press-fit protrusion 141 is removed from the terminal plate insertion portion 140 of the contact pin 100 and fixed as follows.

No press-fit protrusion is formed in the terminal board insertion portion 140A of the contact pin 100A, and the adhesive sheet 240A is placed in the recess 230A around the through hole 210A of the terminal board 200A.

It is inserted into the through hole 510. As a result, the board press-fitting portion 130A of the contact pin 100A is inserted into the through hole 310 of the circuit board 300.
The contact portion 110A of the contact pin 100A is arranged in the connector receiving recess 531 of the connector housing 500.

Thereafter, the contact pin 100A is attached to the through hole 2 of the terminal plate 200A by melting the adhesive sheet 240A using an electric heater or the like and cooling it naturally or forcedly.
Fixed at 10A.

Finally, remove the insertion jig 800 and connect the connecting band 150A.
After removing the terminal board housing, the terminal board housing can be installed.

In the above description, the insertion of the contact pins 100, 100A into the terminal plates 200, 200A and the circuit board 3
Although the arrangement to 00 is performed in a separate process, this may be performed in a series of operations.

Furthermore, in the above description, the fitting key portion 432 uses only the single terminal plate housing 400;
As shown in FIG. 8, the fitting key portion 432 may be used in combination with a plurality of terminal plate housings 400A. Similarly, the terminal plate housings 400, 400A having the fitting key portion 432 and the terminal plate housing having no fitting key portion may be used in combination.

Although the structures on both sides of the circuit board 300 are different from each other in the above description, they may have substantially the same structure.

That is, the other terminal board 200B is the circuit board 300.
It is disposed on one surface of the terminal board 200, that is, the surface on which the terminal board 200 is not attached. The other terminal board 200B has a through hole 210B and a fixed step part 220B.
It is formed similarly to 00. In addition, a locking leg 230B is also formed on the other terminal board 200B, and by being engaged with the through hole 330 of the circuit board 300, the other terminal board 200B is fixed to the circuit board 300.
0B is fixed.

The other terminal board 200B has a terminal board housing 40.
Another terminal board housing 400A having the same structure as 0 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 clear 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 installed in advance on a terminal board separate from a circuit board, and then the plurality of contact pins are arranged 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 allows the work of arranging the multiple contact pins on the circuit board to 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 the terminal board housing is provided with, for example, a fitting key part to connect a mating connector. Since it is specified, it has the effect of being able 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 an effect that can be implemented in the work process. Furthermore, in the present invention, since the plurality of contact pins are implanted in the terminal board prior to arrangement on the circuit board, the positioning of the plurality of contact pins in the direction perpendicular to the circuit board is performed at the time of implantation in the terminal board. This has the effect of making it possible to determine the correct positioning, thereby achieving reliable contact without fear of contact with the 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, the plurality of contact pins are each held at two points, so that the holding strength is sufficient. It has the effect of ensuring.
