Abstract: An electric connector includes terminal holder including mating-connection space surrounded by holder base and two arms, insert-receiving portion defined at bottom side of holder base, mating-connection plate extended from the holder base and suspended in the mating-connection space and conducting terminals mounted in the mating-connection plate, and circuit board including plug portion inserted through the insert-receiving portion into the mating-connection space of terminal holder, two openings coupled to the arms of terminal holder, upper and lower metal terminals mounted on opposing top and bottom sides of plug portion, planar portion abutted to the bottom surface of mating-connection plate and a plurality of contacts arranged at the back side of the planar portion for the bonding of conducting terminals. Thus, the electric connector has advantages of low profile and low manufacturing cost and is practical for use in a mobile electronic device having light, thin, short and small characteristics.

Abstract: A card connector includes a housing defining multiple accommodation chambers, pressure boards respectively and vertically movably accommodated in the accommodation chambers, each pressure board having slots and rear bearing portions protruding over the top wall, and multiple sets of metal terminals mounted in the housing and respectively curving upwardly forwards in the accommodation chambers to support the respective pressure boards in the respective accommodation chamber. By means of the effect of the rear bearing portions of the pressure boards, the inserted memory card touches only the matching metal terminals and the other metal terminals that do not match are kept away from the inserted memory card, preventing damage.

Abstract: A fool-proof card connector includes a housing that has an opening, a card-receiving space, a chamber in a sidewall at one side of the chamber, a stop block that is pivotally mounted in the chamber and has a stop face, and a spring member mounted in the chamber for biasing the stop block toward the outside of the chamber to a biased position where the stop face of the stop block is suspending in the card-receiving space to stop incorrect insertion of a MS memory card.

Abstract: A multi-in-one card connector includes a base having two upright sidewalls and a downwardly backwardly extending sloping groove at each upright sidewall, and two slanting, two terminal sets mounted in the base at different elevations, a partition plate mounted in the base and movable along the downwardly backwardly extending sloping grooves of the upright sidewalls between two positions to control insertion of only one single card member into contact with one terminal set in the base, a cover plate covering the base, and two spring members connected between the base and the partition plate to support the partition plate in one of the two positions.
