[Problems to be Solved by the Invention] When the conventional surface mount type connector described above is fixed to a printed wiring board to which the connector is attached, it is difficult to mechanically connect the lead wire and the printed wiring part by simply soldering. Due to insufficient strength, it was necessary to use screws to fix the printed circuit board and the connector. However, when using such screws, it is necessary to provide at least two or more through holes in the mold part in advance for the screws to pass through, and also to provide screw holes in the corresponding printed circuit board to engage the screws. However, extra time is required to process the above-mentioned screw holes to be provided on the printed circuit board and through holes to be provided in the molded part of the connector, and it is also necessary to provide the printed wiring section to be provided on the printed circuit board using the screw holes provided on the printed circuit board. It had the disadvantage of placing restrictions on location.

An object of the present invention is to mechanically fix the connector to the printed circuit board without requiring the above-mentioned screw holes in the printed circuit board and without providing screw through holes in the molded part. The purpose of the present invention is to provide a surface mount type connector that can

[Means for Solving the Problems] A surface mount type connector of the present invention has a conductive terminal having a lead wire at one end and a molded part made of an insulating material for fixing this terminal, and is attached to a printed circuit board. The mold part is attached to the printed circuit board in such a state that the lead wire can be soldered to the end of the printed wiring part provided, and the longitudinal direction of the terminal is orthogonal to the planar side edge of the printed circuit board. In a surface mount type connector that is fixable and in which the other end of the terminal fits into a corresponding terminal of another connector, a longitudinal side of the lead wire is provided on the side of the molded portion with respect to the terminal where the lead wire is located. When the printed circuit board has a bottom surface parallel to the direction perpendicular to the direction, and the wide side of the printed circuit board fits into the inner surface and the side edge of the printed circuit board touches the bottom surface, one end of the lead wire is the end of the printed wiring. and a groove provided to be located in the section.
