Card edge connector with switch type retainer

摘要

A card edge connector includes an insulative housing defining a central slot for receiving a circuit board. A block is formed on an end of the housing and defines a cavity in an outside surface thereof. A socket defined by two opposing arc sections is formed inside the cavity. A switching button includes a pivot and first and second side sections extending from the pivot and inclined with respect to each other. The button is arranged in the cavity with the pivot rotatably received and retained in the socket whereby the button is rotatable about the pivot between a first position where the first side section is moved into the cavity while the second side section is moved out of the cavity and a second position where the first side section is moved out of the cavity while the second side section is moved into the cavity. A latch pin extends from the first side section. The latch pin engages a notch defined in the circuit board when the button is in the first position thereby securing the circuit board in the connector. The latch pin disengages from the notch when the button is in the second position thereby releasing the circuit board from the connector.
