An ejector mechanism for use in a card connector comprises a guiding arm defining a channel and a reception cavity in communication with the channel. A push bar is slidably received in the channel and in an intermediate portion thereof defines a slot and a cutout narrower than and communicating with the slot thus forming a first digit confronting and spaced from a second digit by the cutout. A spring device includes a first section firmly enclosing the first digit and a second section loosely enclosing the second digit and the spring device is retained in the reception cavity of the guiding arm. A lever device has a driving end connected to one retaining end of the push bar thus when the push bar slides in the channel of the guiding bar the lever device is driven by the push bar to force the card connector to eject a memory card. The spring device is compressed upon a push on the push bar for ejecting the memory card and the spring device reverts to force the push bar back to its original position upon release of the push.

A connector assembly (10, 10') for receiving electrical cards seated on a rigid mother board (12, 12'), includes the plural electrical card connectors (20, 20'), a flexible printed circuit (50, 50') and a connecting means (30, 30') wherein the plural connectors (20, 20') further includes an insulative housing (26, 26') means receiving a plurality of contacts (24, 24') and a shell means (40, 40') integrally forming a plurality of terminal (44, 44') therewith. The flexible printed circuit board (50, 50') includes a plurality of holes (521, 521') formed adjacent to an end thereof and solderably connected with the terminals (44, 44') and the contacts (24, 24') of the connectors (20, 20'), and a plurality of printed pads (581, 581') formed adjacent to the other end thereof and electrically connected with a plurality of circuit pads (18, 18') formed on the rigid mother board (12, 12') by means of the connecting means (30, 30'). Since the electrical connection between the electrical card connectors (20, 20') and the rigid mother board (12, 12') only utilizes one flexible printed circuit board (50, 50') and one connecting means (30, 30'), the connector assembly (10, 10') can save more space on the rigid mother board (12, 12') and achieve a shorter electrical transmittal path.
