ABSTRACT:
A card frame having a number of pairs of vertically spaced card guides for receiving cards provided with plug connectors. Each pair of card guides is associated with a socket connector to establish electrical contact. A double-armed lever is pivotally mounted on each card by means of a pin at the lower front corner of the card and is adapted to be pivoted from an initial position, which is oblique to the forward edge of the card, into a latching position in an abutting relationship with the forward edge of the card. The short lever arm terminates in a hook and heel configuration. The hook portion is engageable with a receptacle fixed on the frame, as the card is inserted and the lever is pivoted upward into the latching position, with the hook bearing against the receptacle counter to the direction of insertion of the card. The heel portion bears against a front surface area of the frame as the lever is pushed downward into its initial position and the card is ejected. Solely by the particular construction of the mounting means of the lever on the card and the location of mounting with respect to the hook at the end of the shorter lever arm, a definitive non-detachable fully plugged-in position of the card is attained.
