  • Patent number: 5797762
    Abstract: In a mechanism for driving a plurality of pin contacts of an edge connector of a memory card assembly in a lateral direction from positions adjacent to socket contacts to bring the pin contacts into contact with the socket contacts of a card receiving connector, the mechanism comprises a pin driving plate having a cam hole and pin contact receiving holes and laterally slidably mounted on the card receiving connector. An actuator rod is removably and rotatably mounted in the card receiving connector and is provided with an eccentric pin portion engaging with the cam hole so that the pin driving plate is laterally driven by engagement between the cam hole and the eccentric pin portion when the actuator rod is rotated. Thus, the pin contacts received in the pin contact receiving holes are brought into contact with the socket contacts.
