Card ejector mechanism of a connector, having an elastic mechanism pushing an inserted card by depressing a button mechanism

摘要

An ejector mechanism for a connector comprises a receptacle defined in a top surface of a header of the connector and an elastic device received in the receptacle. An elastic ejection plate is adapted to force the elastic device to deform and store tension when an external card is manually inserted into the header of the connector in a first direction and exerts a force on the ejection plate along the first direction. A button device projects from the ejection plate. A retaining plate is fixed to the connector and defines a first hole and a second hole for respectively receiving the button device at different statuses. The button device is moved from the first hole to the second hole when the elastic ejection plate is pushed by the inserted card in the first direction. The button device receives a force from the elastic device and returns to the first hole when it is depressed downward below a retention region of the second hole.
