Abstract
A card edge connector includes an ejector (3) with a pushing portion (32) extending from distal end thereof, the ejector (3) moves between an opening station and a locking station, and at least pair detecting contacts (4) which includes two detecting pins (41, 42), one of the detecting pins defines a spring engaging arm having an engaging portion (425) opposite to the pushing portion (32) which presses on the engaging portion (425) in the locking station or leave the engaging portion (425) in the opening station, thereby making the two detecting pins engage or disengage with each other for detecting if a memory card is inserted in the card edge connector or not.
Claims20
A card edge connector for engaging with a memory card, comprising:
- a longitudinal insulative housing comprising a pair of sidewalls, an inserting slot therebetween for receiving the memory card and a receiving opening communicating with the inserting slot;
- a plurality of contacts arranged two arrays along a longitudinal direction, respectively being disposed at the both sidewalls while opposite to each other in a width direction perpendicular to the longitudinal direction;
- an ejector being mounted into the receiving opening and comprising a pushing portion extending towards the insertion slot from distal end thereof, the ejector movably engages with the insulative housing and thus moves between an opening station in which the memory card is permitted inserted into or pushed outwards and a locking station in which the memory card is positioned in the inserting slot;
- and
- at least one pair of detecting contacts comprising a first detecting pin and a second detecting pin received and retained in corresponding receiving slots formed by the insulative housing;
- wherein the second detecting pin comprises a spring engaging arm having an engaging portion protruding to the insertion slot and opposite to the pushing portion which presses on the engaging portion in the locking station or leave the engaging portion in the opening station, thereby making the second detecting pin engage or disengage with the first detecting pin for detecting whether the memory card is inserted in the card edge connector or not.
A method of making a care edge connector mounting on a printed circuit board with a switch function thereof, comprising steps of:
- providing an insulative housing with an elongated slot extending along a longitudinal direction;
- providing a plurality of contacts in the housing beside said slot, each of said contacts including a contacting section extending into the slot and a tail section for mounting to the printed circuit board;
- providing a tower portion at one end of the housing in said longitudinal direction;
- providing an ejector in the tower portion, said ejector including an upper locker and a lower kicker for use with an upper notch and a lower edge of a memory module adapted to be received in the slot, said ejector moveable via rotation between an inner locking position and an outer ejecting position;
- providing at least one detect pin around the tower portion with one tail for mounting to the printed circuit board;
- wherein
- when the ejector is moved to the outer position, the detect pin performs a first circuit path while when the ejector is moved to the inner locking position, the detect pin performs a second circuit path different from the first circuit path.
A card edge connector for use with a memory card having an upper notch and a lower edge and with a printed circuit board, comprising:
- an insulative housing defining an elongated slot extending along a longitudinal direction thereof for receiving said memory card;
- a plurality of contacts disposed in the housing beside the slot, each of said contacts defining a contacting sections extending into the slot, and a mounting tail extending outside of the housing for mounting to the printed circuit board;
- at least one tower portion located around at one end of the housing in said longitudinal direction;
- at least one detect pin located around the tower portion and having a tail for mounting to the printed circuit board;
- and
- one ejector pivotally mounted in said tower portion and defining an upper locker for locking into the notch of the memory card and a lower kicker for ejecting the bottom edge of the memory card;
- wherein
- said ejector is rotatable between an inner locking position and an outer ejecting position, and the ejector physically pushes a part to actuate an electrical circuit path with regard to the detect pin when said ejector is located in the inner locking position, while said ejector is spaced from the part not to actuate said electrical circuit path when the ejector in the outer ejecting position.
