Connector with ejector

A card edge connector for use with a card, comprising:

• an insulative elongated housing defining a central slot for receiving the card therein;
• a plurality of passageways positioned on two sides of the slot for receiving a corresponding number of contacts therein;
• a pair of cavities formed on two opposite ends of the housing for receiving at least a rotative ejector therein;
• a pair of retention bars positioned adjacent each of the cavity;
• and
• an alignment post positioned in one of said cavities opposite to said ejector, said alignment post including a shortened main body having a stabilization section at a top portion with a channel having an oblique section guiding but not retaining the inserted card and said channel in the stabilization section being in alignment with the central slot wherein a bottom surface of the alignment post abuts against a floor surface of the housing and the stabilization section engages the corresponding retention bars whereby said alignment post is retained within the corresponding cavity without possibility of movement.

An arrangement for connecting a card to a mother board, comprising:

• an insulative elongated housing mounted on the mother board;
• said housing defining a central slot for receiving said card therein and a plurality of contacts positioned by two sides of the slot for engagement with circuit pads on the card;
• at least a cavity formed at one lengthwise end of the housing for receiving a rotatable ejector therein;
• a pair of retention bars positioned adjacent said cavity;
• wherein
• when said card is a first type card which is of a shorter type or the card is substantially in a vertical use manner, a first type ejector can be assembled into the cavity for cooperation with the first type card, and said first type ejector has a shorter body including a stabilization section at the top defining a channel having oblique section guiding but not retaining the inserted card for alignment with the central slot whereby said stabilization section is engaged with the retention bars;
• alternately, when said card is a second type card which is of a taller type or the card is substantially in a horizontal use manner, a second type ejector can be assembled into the cavity for cooperation with the second type card, and said second type ejector includes a long main body having a pair of stopper blocks on two side surfaces and a locking peg at a top portion whereby said stopper blocks are outside the cavity for engagement with the retention bars and the locking peg extends toward the central slot above the retention bars for engagement within a notch formed on an edge portion of the second type card.

A card edge connector comprising:

• an insulative elongated housing defining a central slot for receiving a card therein;
• a plurality of passageways positioned on two sides of the slot for receiving a corresponding number of contacts therein;
• a pair of cavities formed on two opposite ends of the housing at least one of said cavities receiving an ejector therein;
• a pair of retention bars positioned adjacent each of the cavities;
• at least one ejector including a tall main body having a kicker section extending horizontally toward the central slot at a bottom portion thereof and a locking peg extending horizontally toward the central slot, opposite to the kicker section in vertical direction, at a top portion of the main body, wherein said ejector further includes a pair of stopper blocks laterally extending from two side surfaces of the main body, and each stopper block is engaged with a corresponding retention bar for restraining the ejector from further rotatably moving toward the central slot when the locking peg of said ejector locks the card.
