Abstract An improved receptacle for a key-like device containing an embedded electronic circuit component with electrical leads extending to the surface of the key to form electrical contact areas thereon. The receptacle defines a keyway in which a plurality of exposed contact pins are positioned and spaced inside the receptacle to correspond to the spacing of the electrical contact areas on the key-like device for mating therewith upon insertion of the key device. The receptacle includes a protection sleeve which functions as a guard means for the contact pins. The receptacle is designed to be combined with a printed circuit board by insertion of the outer ends of the contact pins, wich extend through and out of a side of the receptacle, into the circuit board. The contact pins may be received into a variety of predetermined patterns of connectors on the circuit board facilitating electrical connection of the receptacle contact pins to a variety of standardized electrical connectors. Wave soldering may be used to attach the receptacle contact pins to the printed circuit board.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
160 words
An electrical receptacle which is electronically activated by insertion and rotation of an electronic key-like device having electrical contact surface areas thereon for mating with corresponding contacts in the receptacle, the receptacle consisting of: (a) an electrical contact support member, having adjacent spaced inner and outer surfaces; (b) a set of spaced electrical contact pins arranged along said contact support, the pins being fixed in the support and extending therethrough such that each pin has free opposite ends extending away from said support on both the inner and outer surfaces thereof, respectively; (c) a guard member defining a keyway, the member being constructed and arranged to allow access to the contact pins only when the key-like member is inserted into the keyway and rotated approximately 90 degrees, and (d) an enclosure member which mounts above the inner surface of said contact support, the member covering said guard member and leaving at least one end freely accessible to the key-like device.
Claim 2
Dependent Claim
160 words
An electrical receptacle which is electronically activated by insertion and rotation of an electronic key-like device having electrical contact surface areas thereon for mating with corresponding contacts in the receptacle, the receptacle consisting of: (a) an electrical contact support member, having adjacent spaced inner and outer surfaces; (b) a set of spaced electrical contact pins arranged along said contact support, the pins being fixed in the support and extending therethrough such that each pin has free opposite ends extending away from said support on both the inner and outer surfaces thereof, respectively; (c) a guard member defining a keyway, the member being constructed and arranged to allow access to the contact pins only when the key-like member is inserted into the keyway and rotated approximately 90 degrees, and (d) an enclosure member which mounts above the inner surface of said contact support, the member covering said guard member and leaving at least one end freely accessible to the key-like device.
Claim 3
Dependent Claim
43 words
The receptacle of claim 1 in which the contact support has at least one track on the inner surface and running parallel to the outer edge of said inner surface, and wherein said track is between said contact pins and said outer edge.
Claim 4
Dependent Claim
28 words
The receptacle of claim 1 in which a wall member is attached to one end of said contact support, said wall member extending upward from said inner surface
Claim 5
Dependent Claim
50 words
The receptacle of claim 1 in which the guard member is comprised of: (a) a pair of elongated wall shields, and (b) a plurality of disks attached to the wall shields such that the faces of the wall shields are parallel such that said disks are parallel to each other.
Claim 6
Dependent Claim
35 words
The guard member of claim 4 wherein one end of said guard member is covered by a slotted member and the opposite of said guard member is sized and shaped to fit said key-like device.
