Card edge connector having a collapsible ejector

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

• an insulative housing defining an insulative elongated housing along a longitudinal direction with a receiving slot therein for receiving the memory module, a pair of towers located at two opposite ends of the housing in said longitudinal direction, each of said towers defining a lower middle wall and a pair of side walls;
• a plurality of contacts disposed by two sides of the receiving slot along said longitudinal direction;
• at least one ejector pivotally disposed in one of said towers, said ejector including a lower base portion and an upper locking portion pivotally mounted upon the lower base portion, a pair of pivots formed upon the lower base portion so as to allow said ejector to be pivotal with regard to the tower;
• wherein
• the lower base portion includes a lower ejecting section for ejecting the daughter module, and said upper locking portion includes an upper locking section for locking the module module;
• wherein
• generally, said ejector is located in an upstanding/unfolded state in which both said lower base portion and said upper locking portion stand upwardly so as to be adapted to be outwardly rotated away from the receiving slot in said longitudinal direction, and is adapted to be in a folded state in which the upper locking portion is inwardly rotated toward the receiving slot and moved to a lying position for lowering a height thereof while the lower base portion still upwardly stands;
• and
• said upper locking portion forms a receiving cavity to receive an upper region of the lower base portion, and a preventing wall formed on an outer side of the receiving cavity to prevent the upper locking portion from being outwardly rotated with regard to the lower base portion, and an opening formed in an inner side of the receiving cavity and opposite to the preventing wall to allow the upper locking portion to be inwardly rotated toward the receiving slot relative to the lower base portion so as to have the ejector in said folded state.

An ejector for use with a card edge connector which includes an insulative housing with an elongated receiving slot for receiving a memory module, and a pair of towers at two opposite ends along a longitudinal direction wherein said ejector is pivotally located in one of said tower, said ejector comprising:

• a lower base portion on which a pivot is formed for pivotally mounting to the tower, and a lower ejecting section for ejecting the memory module;
• and
• an upper locking portion pivotally mounted upon the lower base portion, on which an upper locking section is formed for locking the memory module;
• wherein
• a pivot between said lower base portion and said upper locking portion is located around a lower region of the upper locking portion and an upper region of the lower base portion, and through said pivot the ejector can be in either an unfolded state where the upper locking portion and the lower base portion are both in an upstanding manner, or a folded state where the upper locking portion is angled with the lower base portion;
• and
• said upper locking portion forms a receiving cavity to receive an upper region of the lower base portion with an opening being located in an inner side of the receiving cavity for allowing the upper locking portion to be inwardly rotated with regard to the lower base portion when said ejector is in the folded state, and a preventing wall being located on an outer side of the receiving cavity for preventing the upper locking portion from being outwardly rotated with respect to the lower base portion when the ejector is in the folded state.
