Abstract
Abstract A retainer (10) for use with a card edge connector (1) includes an insulative housing (16) defining a cavity (22) surrounded by a pair of side walls (18) and a pair of end walls (20) with mounting stands integrally formed on its exterior. A pair of towers (26) are formed at two opposite ends of the housing (16) adjacent the end walls (20). Each tower (26) includes a vertical channel (28) for receiving a side edge section (13) of a card (14) which is adapted to be received within the card edge connector (1). A platform (30) extends horizontally and outward on the top of the tower (26). A sliding block (50) is attached onto the platform (30) and defines a first innermost position for locking the card (14) and a second outermost position for allowing loading/unloading of the card (14) with regard to the connector (1). A pair of resilient angularly deflected tangs (38) are positioned on to top surface (40) of the tower (26) for engagement with a first indent (60) and a second indent (61) formed on the underside of the sliding block (50) for orienting the sliding block in the first locking position or in the second free position.
