Electrical connector for card having surface contact point

摘要

A movable member 12 is attached to the frame 3 so as to move between a release position and a lock position. A first latch projection 14 is provided on the movable member. A lock arm 7 extends upwardly from the base beyond the first latch projection at the lock position. A second latch projection extends downwardly from the lock arm toward the base at a position between the first latch projection at the lock position and the end of the base by a distance (b) defined by a following inequality: $wherein\; (a)\; is\; a\; thickness\; of\; the\; movable\; member\; at\; the\; first\; latch\; projection\; and\; (c)\; is\; a\; maximum\; amount\; of\; deformation\; of\; the\; contact\; portion\; of\; the\; contact\; element\; made\; by\; the\; card\; pressed.\mathop{\mathrm{image}}$
