摘要：A guide mechanism (14) prevents an improperly oriented PC card (10) frombeing inserted a significant distance into a PC slot. A pair of PC card guide mechanisms(14,16) are coupled to a PC male connector (12). A PC card (10) is received at the guides(14,16) as the card is inserted and pushed toward the male connector. Each guide
mechanism includes a proximal end (88,188) that engages an edge (18,20) of the maleconnector (12), and a distal flanged end (74,174) that receives the PC card (10). A guiderail (76,176) extends between the proximal (88,188) and distal (74,174) ends of each guidemechanism (14,16). Typically, a PC card (10) is inserted female edge (22) first into a PCslot. The card first encounters the flanged ends (74,174) of the guides (14,16) whichdirect the card (10) onto the guide rails (76,176). At least one guide mechanism (14)includes a flexible arm (80) along its guide rail (76). At the tip of the arm (80) is a keyingmechanism (82) responsive to the PC card orientation. When the PC card is properlyoriented, the card (10) slides over the keying mechanism (82) pushing it aside to traversethe guide rail (76). When the PC card is improperly oriented, the card is blocked by thekeying mechanism (82 at 96) so as not to traverse the guide rail (76). The inventive keyingmechanism is located away from the male connector (12) and toward the distal end (74)of the guide mechanism (14). As a result, an installer feels resistance of an improperlyoriented card before the card travels a significant distance within the slot. In particular,the installer receives tactile feedback by feeling the resistance and visible feedback byseeing that the card is not installed nearly as far as it should when a proper connectionoccurs. With a significant length of the PC card protruding from the slot, the card is easilygrasped and removed. Automatic ejection is not needed.
