A socket contact 1 having a fitting contact portion 3 and an external connection terminal 4 connected to the rear end is inserted from the rear opening 6a into a housing hole 6 which is individually spaced apart and penetrates through the insulating housing 5. A memory card connector is known in which the fitting contact portion 3 is inserted first, and a locking claw 7 protruding from the press-fitting portion 2 is press-fitted and locked onto the inner wall surface of the accommodation hole 6.

is located on the same plane as the rear opening end 6a of the accommodation hole 6, and the external connection terminal (lead part) 4 connected to the rear end of the press-fitting part 2 is on the same plane as the bottom plate of the press-fitting part 2. Since the external connection terminals 4 are soldered to the printed wiring board 10 which extends and is close to the rear opening end 6a, during soldering,
The problem is that the molten solder liquid is sucked up into the U-shaped press-fitting part 2 by capillary action, and the sucked-up solder 11a penetrates into the fitting contact part 3 and becomes an obstacle to the insertion and fitting of the pin contact 8. It was hot.

同一符号を示してある。Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. FIG. 1 shows a memory card connector according to the present invention, and the basic structure of the socket contact 1 and insulating housing 5 is the same as the conventional product shown in FIG. 4, so the same components will be explained. The same symbols are shown.

a is housed a certain distance d further inward from the rear opening end 6a of the housing hole 6. In addition, the rear part 6c of the accommodation hole 6 is, as clearly shown in FIG.
The cross-sectional shape is a combination of a circular hole through which the annular portion of the fitting contact portion 3 is inserted and a circular square hole through which the press-fit portion 2 having a U-shaped cross section is inserted.

らである。 With the above configuration, as shown in FIG. 3, when the external connection terminals 4 are soldered 11 to the printed wiring board 10 built into the card, the molten solder liquid flows onto the rear end surface 5a of the insulating housing 5. Therefore, it is blocked and does not enter the press-fit portion 2 through the rear open end 6a. This is the insulation housing 5
Since the plastic material such as nylon that constitutes the housing hole 6 has the property of repelling substances with high specific gravity such as solder, the solder 11 is not sucked up by capillary action at the rear open end 6a of the housing hole 6, and press-fitting is prevented. This is because it reliably prevents solder from entering the portion 2.

By simply placing the rear end surface 2a of the press-fitting part 2 within a certain distance from the rear opening end 6a of the receiving hole 6, the solder 11 for connecting the external connection terminal 4 is brought into fitting contact from the press-fitting part 2. This has the effect of effectively preventing entry into the portion 3.
