Description

  The present invention relates to a composite connector for a memory card that can be applied to a plurality of types of memory cards having different sizes and shapes, and has an area occupied by a board to be mounted as small as possible.

As the composite connector 11 mounted on the substrate 10, one shown in FIGS. 7 and 8 is known as one that can handle a plurality of types of memory cards having different sizes and shapes (Patent Document 1).
The composite connector 11 shown in FIG. 7 has a two-stage stacked structure of a lower connector 13 and an upper connector 14 that are both inserted into and removed from the housing 12 in the horizontal direction. The second memory card 16 is inserted into and removed from the upper connector 14 in a direction orthogonal to the first memory card 15. In the first memory card 15 and the second memory card 16, substantially half a part and b part project from the housing 12 in a state where the tip electrode part is inserted into the composite connector 11.

The composite connector 11 shown in FIG. 8 has a double-layered structure in which a lower connector 13 inserted in and removed from a housing 12 and an upper connector 14 inserted and removed in a vertical direction are stacked in a housing 12. The card 15 is inserted / removed in the horizontal direction, and the second memory card 16 is inserted / removed in / from the upper connector 14 in the vertical direction. Of these, the first memory card 15 has an a portion that protrudes from the housing 12 in a state of being inserted into the composite connector 11 with the electrode portion at the tip first. The second memory card 16 is fitted into the upper connector 14 and is held by a locking tool or a lid (both not shown).
