Abstract: An adapter for connecting a card connector to a mother board consists of a dielectric housing having a front face proximate the card connector and a bottom face proximate the mother board, and a metallic shielding covering a top face, a rear face and side walls of the housing. A number of contacts are fixedly received in the housing and extend from the front face to the bottom face. The contacts are electrically engaged with contacts of the card connector. A top portion of the shielding is engaged with a shielding of the card connector. The shielding of the adapter further forms a plurality of grounding tabs extending between tail portions of selected contacts of the adapter, thereby reducing cross-talk therebetween.

Abstract: 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.
