Abstract
Abstract A guide mechanism prevents an improperly oriented PC card from being inserted a significant distance into a PC slot. A pair of PC card guide mechanisms are coupled to a PC male connector. A PC card is received at the guides as the card is inserted and pushed toward the male connector. Each guide mechanism includes a proximal end that engages an edge of the male connector, and a distal flanged end that receives the PC card. A guide rail extends between the proximal and distal ends of each guide mechanism. At least one guide mechanism includes a flexible arm along its guide rail. At the tip of the arm is a keying mechanism responsive to the PC card orientation. When the PC card is properly oriented, the card slides over the keying mechanism pushing it aside to traverse the guide rail. When the PC card is improperly oriented, the card is blocked by the keying mechanism so as not to traverse the guide rail. The inventive keying mechanism is located away from the male connector and toward the distal end of the guide mechanism. As a result, an installer feels resistance of an improperly oriented 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 by seeing that the card is not installed nearly as far as it should when a proper connection occurs. Automated ejection is not needed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
165 words
A guide apparatus at an integrated circuit connector for receiving an integrated circuit card, the integrated circuit card having a first edge for mating with the integrated circuit connector, a first end of the first edge defining a first groove that runs from the first edge along a perpendicular second edge, the guide apparatus comprising: a first rail having a proximal end at the integrated circuit connector and a distal end for receiving the integrated circuit card; and a keying guide positioned away from the proximal end of the first rail in alignment with the first groove of a received integrated circuit card when the integrated circuit card has a first orientation, wherein the keying guide is movable out of the path of the integrated circuit card when the received integrated circuit card has the first orientation, and wherein the keying guide resists movement out of the path of the integrated circuit card when the received integrated circuit card has other than the first orientation.
Claim 2
Dependent Claim
165 words
A guide apparatus at an integrated circuit connector for receiving an integrated circuit card, the integrated circuit card having a first edge for mating with the integrated circuit connector, a first end of the first edge defining a first groove that runs from the first edge along a perpendicular second edge, the guide apparatus comprising: a first rail having a proximal end at the integrated circuit connector and a distal end for receiving the integrated circuit card; and a keying guide positioned away from the proximal end of the first rail in alignment with the first groove of a received integrated circuit card when the integrated circuit card has a first orientation, wherein the keying guide is movable out of the path of the integrated circuit card when the received integrated circuit card has the first orientation, and wherein the keying guide resists movement out of the path of the integrated circuit card when the received integrated circuit card has other than the first orientation.
Claim 3
Dependent Claim
30 words
The guide apparatus of claim 1, further comprising a second rail having a proximal end at the integrated circuit connector and a distal end for receiving the integrated circuit card.
Claim 4
Dependent Claim
17 words
The guide apparatus of claim 1, in which the first rail removably engages the integrated circuit connector.
Claim 5
Dependent Claim
182 words
A guide apparatus at an integrated circuit connector for receiving an integrated circuit card, the integrated circuit card having a first edge for mating with the integrated circuit connector, a first end of the first edge defining a first groove that runs from the first edge along a perpendicular second edge, the guide apparatus comprising: a first rail having a proximal end at the integrated circuit connector and a distal end for receiving the integrated circuit card; and a keying guide positioned away from the proximal end of the first rail in alignment with the first groove of a received integrated circuit card when the card has a first orientation in which the keying guide is formed at an arm and comprises: a blocking surface in alignment with the first groove of a received integrated circuit card during insertion of the integrated circuit card at the first orientation, and an inclined surface adjacent to the blocking surface, the integrated circuit card at the first orientation encountering the inclined surface to push the arm out of the integrated circuit card path during insertion.
Claim 6
Dependent Claim
182 words
A guide apparatus at an integrated circuit connector for receiving an integrated circuit card, the integrated circuit card having a first edge for mating with the integrated circuit connector, a first end of the first edge defining a first groove that runs from the first edge along a perpendicular second edge, the guide apparatus comprising: a first rail having a proximal end at the integrated circuit connector and a distal end for receiving the integrated circuit card; and a keying guide positioned away from the proximal end of the first rail in alignment with the first groove of a received integrated circuit card when the card has a first orientation in which the keying guide is formed at an arm and comprises: a blocking surface in alignment with the first groove of a received integrated circuit card during insertion of the integrated circuit card at the first orientation, and an inclined surface adjacent to the blocking surface, the integrated circuit card at the first orientation encountering the inclined surface to push the arm out of the integrated circuit card path during insertion.
Claim 7
Dependent Claim
