Abstract
A card edge connector includes an elongated housing, the housing extends along a longwise direction thereof and has a pair of opposed side walls, a central slot between the side walls, and a tower portion disposed at one end thereof. A plurality of contacts are retained in the housing. An ejector mechanism is rotatable retained in the housing and has a body portion, a flexible arm divided from the body portion and a locking protrusion located on the flexible arm. The lock protrusion is adapted to resist the tower portion during the ejector mechanism rotates with respect to the housing.
Claims15
A card edge connector, comprising:
- an elongated housing extending along a longwise direction thereof and having a pair of opposed side walls, a central slot between the side walls for receiving a memory card, and a tower portion disposed at one end thereof, the tower portion defining a pair of retention walls opposited to each other in a width direction to define a retaining cavity therebetween;
- a plurality of contacts retained in the housing and exposed to the central slot;
- and
- an ejector mechanism rotatable retained in the retaining cavity, the ejector mechanism having a body portion, an operating portion and a locking head oppositely extending from a top end of the body portion in the lengthwise direction, respectively, and an ejecting portion inwardly extending from the body portion, the body portion has a flexible arm, and a locking protrusion located on the flexible arm and outwardly resisting the retention wall during the ejector mechanism rotating with respect to the housing, wherein the flexible arm extends outwardly in the lengthwise direction.
A card edge connector for receiving a memory card, comprising:
- an elongated housing defining a central slot extending along a lengthwise direction thereof, and two tower portions located at two opposite ends thereof;
- two rows of contacts disposed by two sides of the central slot, respectively;
- a pair of ejector mechanisms rotatably disposed in the corresponding tower portions, respectively, each of the ejector mechanisms defining at least one flexible arm extending in the lengthwise direction, and at least one locking protrusion located on the flexible arm and extending toward a first direction perpendicular to the lengthwise direction;
- and
- a pair of stop blocks formed in the tower portion and extending toward a second direction opposite to the first direction and perpendicular to the lengthwise direction, the stop blocks being disposed at two opposite lateral outsides of the ejector mechanism;
- wherein the flexible arm is configured with enough deflection to allow the locking protrusion to pass the stop block in the lengthwise direction when the ejector mechanism is rotated to an upstanding position, wherein
- the flexible arm grows outwards from one lateral surface of the ejector mechanisms.
A card edge connector for use with a memory module, comprising:
- an insulative elongated housing defining a pair of tower portions at two opposite ends with therebetween an receiving slot in a lengthwise direction for receiving said memory module;
- a plurality of contacts disposed in the housing exposed toward the receiving slot;
- and
- a pair of ejectors respectively disposed in the corresponding tower portions, each of said ejector being pivotally mounted to the corresponding tower portion and moveable between an inner locked position and an outer unlocked position;
- wherein
- one of the ejector and the corresponding tower portion is equipped with a flexible retention arm to lock to an immovable portion of the other under condition that the flexible retention arm is engaged with said immovable portion in said lengthwise direction for retaining the ejector in the inner locking position while the flexible retention arm is deflectable in a transverse direction perpendicular to said lengthwise direction to have the flexible retention arm disengaged from the immoveable portion so as to allow the ejector to be moved from the locked position to the unlocked position for releasing the memory module from the housing;
- wherein
- said flexible retention arm extends outwardly in the lengthwise direction.
