Abstract
A connector has an insulative frame (52) and has rows (34, 36) of identical contacts (70) for engaging pads on a smart card, where at least one of the contacts that otherwise could engage a pad, is used to close or open a switch to detect the presence of a smart card.
Claims7
An electrical connector for making electrical connections with contact pads on the active face of a circuit card, comprising:
- an insulative frame with a frame face for substantially engaging said card active face, and a plurality of contacts mounted on said frame and having engaging ends lying above said frame face and being resiliently depressable to positions substantially no higher than flush with said frame face;
- a switch that includes an electrically conductive switch blade that is fixed to said frame and that has a first switch branch that lies in engagement with the engaging end of a first of said contacts before said first contact is depressed by a card, with said first contact having a fixed part that is fixed to said frame and a cantilevered free end portion that extends from said fixed part to said engaging end and that is depressable by a card out of engagement with said first switch branch by bending of said cantilevered free end portion.
An electrical connector for making electrical connections with contact pads on the active face of a circuit card, comprising:
- an insulative frame with a frame face for substantially engaging said card active face, and a plurality of contacts mounted on said frame and having engaging ends lying above said frame face and being resiliently depressable to positions substantially flush with said frame face;
- a switch that includes an electrically conductive switch blade that is fixed to said frame and that has first and second switch branches that lie in engagement respectively with first and second of said plurality of contacts before said first and second contacts are depressed by a card, with said contact engaging ends being depressable by a card out of engagement with said switch branches to open said switch.
An electrical connector for making electrical connections with contact pads on the active face of a circuit board, comprising:
- an insulative frame with a frame face for substantially engaging said card active face, and a plurality of contacts mounted on said frame and having engaging ends lying above said frame face and being resiliently depressable to positions substantially no higher than flush with said frame face;
- a switch that includes an electrically conductive switch blade that is fixed to said frame and that has a first switch branch that lies in engagement with the engaging end of a first of said contacts before said first contact is depressed by a card, with said first contact engaging end being depressable by a card out of engagement with said first switch branch;
- said frame face faces upwardly and has a recess with a recess bottom wall, and said frame has a post projecting up from said bottom wall;
- said switch blade has a mount part with a hole, and said post projects through said hole and has a head that holds said switch blade mount part against said bottom wall, said head having a top lying at about the height of said frame
