Card edge connector with ejector

An ejector for retaining a daughter board in a card edge connector, comprising:

• a main body having a pair of opposite sidewalls, each sidewall comprising a spindle for being pivotally received in the card edge connector;
• a kicker positioned at a bottom portion of the main body for ejecting the daughter board from the card edge connector;
• a locker extending from a top of the main body toward the daughter board for securely retaining the daughter board in the card edge connector;
• and
• a pair of elastic arms extending from the top and opposite to the locker, each arm including a retention protrusion engaged with the connector for preventing the ejector from moving from a retaining position to a released position.

A card edge connector comprising:

• an elongated housing defining a central receiving channel, at least one tower positioned at one end of the housing, said tower providing at least one guide wall thereof;
• and
• at least one ejector rotatably disposed in said tower, said ejector including a main body with a locker on an upper portion for securely retaining a daughter board in the central receiving channel;
• wherein
• a retention protrusion is formed on said ejector with thereon an abutment surface latchably engaged with the guide wall, and said ejector includes an elastic portion on the upper portion and extending opposite to the locker, said elastic portion is manually depressed along a first direction to actuate the retention protrusion to move along said first direction for disengagement from the guide wall.

A method of two-step release of a daughter board from a connector, comprising the steps of:

• providing a housing with a central receiving channel and two towers at two opposite ends thereof, each of said towers defining at least one guide wall;
• providing an ejector rotatably received in each of said towers, each of the ejector defining a main body with a locker at an upper portion thereof, and at least one retention protrusion is formed on the ejector, and the ejector includes an elastic portion extending opposite to the locker and engaged with or disengaged from the corresponding guide wall;
• providing the daughter board latchably received within the central receiving channel by the locker of each of said ejectors;
• when releasing the daughter board from the housing, first along a first direction depressing the elastic portion to release the retention protrusion from the guide wall, and secondly along a second direction rotatably moving the ejector to remove engagement between the daughter board and the locker of each of said ejectors wherein said first direction and said second direction are perpendicular to each other.
