This means that the displacement of the connection terminal 211c- ₃ including the protruding portion 311a is restricted in the width direction by the slit groove 316c and the displacement in the thickness direction is restricted by the concave portion 511a of the guide 511. Means that

Therefore, both the displacement in the width direction and the thickness direction as the connection terminal are all regulated by the guide 511, so that the bracket 31 explained in FIG.
The connector 51 that does not require the connector 7 can be configured.

In FIG. 15 for explaining a method of mounting the connector 5 on a circuit board, (15-1) shows a state before mounting in a sectional view, and (15-2) shows a state after mounting. It is shown as a partial cross section.

That is, in (15-1), each of the plug terminals 21
Only 1 _-21 ～211 the connection terminals 211c _{-3 -24} is in a state of protruding.

In this case, in the connector 51, FIG.

It is necessary to press-fit into the through hole 13 c of the circuit board 13. Therefore, the pressing jig 49 described with reference to FIG. (15-2)
Can be implemented as shown in FIG.

The connector 51 has an advantage that the bracket 317 required for the connectors 31 and 41 described above can be eliminated. In addition, the connection terminal area is a pin-shaped connection terminal 111 with a bulge described with reference to FIG.
In the case of a pin-shaped connection terminal with a bulge similar to that of c- ₂ , the circuit board 1 is subjected to the same steps as in FIG.
3, a connector having a reduced height can be formed.
