  • Patent number: 8113861
    Abstract: The connector of the present invention includes a base having a plurality of terminals for contacting the card and a cover for holding the card. In an embodiment, the base has two resilient plates extending from the base, each of the plates has a distal end at which an inner hinging portion is formed. The cover has an outer hinging portion engaged with the inner hinging portions to form a hinge such that the cover is pivotally mounted on the base and movable in relation to the base. Each of the resilient plates is L-shaped such that the hinge is deflectable from the base.

  • Patent number: 8070498
    Abstract: The present invention relates to a contact and an electrical connector having such contacts. The contact is formed as a single piece of elastic metal sheet and includes a base frame and a spring arm restrained by the base frame in a preload state. The base frame includes two side walls each having a stopper projection formed in a plane within which a corresponding side wall is disposed. The spring arm is formed with opposite projections which are pressed down and constrained in position by the stopper projections respectively. The contact can be manufactured in a simple way and presents a high reliability.

  • Publication number: 20090137136
    Abstract: A connector for connecting a card to a printed circuit board is provided. The connector includes a housing Z and a plurality of terminals. The housing includes a plurality of slots and at least one trench disposed in the vicinity of each of the plurality of slots. Each of the plurality of terminals includes a contact portion to be in contact with the card, an anchoring portion, four feet extending vertically from the anchoring portion, and a soldering portion extending from the anchoring portion and to be soldered to the printed circuit board. The terminal is mounted on the housing with at least one of the feet of the terminal inserted in at least one trench. The soldering portion is offset from the contact portion so that the contact portion will not come into contact with the soldering portion (when the contact portion is pressed towards the soldering portion, thereby providing a low-profile connector.
