Title: Connector for card edge
Inventor: HAWAADO UORESU ANDORIYUUSU JIY
IPC: H01R12/70
Filed: 1983-03-31
Abstract: The invention disclosed herein relates to a biasing means provided in one end of a card-receiving slot of a card edge connector. The biasing means includes a spring loaded wedge slidably positioned in a sloping passage at one end of the slot. The wedge includes a vertical surface which engages a side of the card as the card is inserted in the slot. The wedge moving down the sloping passage increases the slot length to accommodate the card width without exerting significant longitudinal force against the end walls of the connector. Further, the wedge cannot be moved up the passage by an uneven force being exerted on the card; accordingly, the card can only be removed from the slot in a straight line.
