Abstract
Abstract A memory card assembly is provided having a one-piece construction including a cardedge receptacle for slidingly receiving the conductive fingers of a printed circuit board and providing for an electrical connection without soldering. The one-piece construction is achieved by the injection molding of an internal frame to capture the protruding edges of the top and bottom metallic covers. Sufficient normal force of the cardedge receptacle is maintained by a brace member.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
159 words
A one-piece memory card assembly for housing a semi-conductor device comprising: a top metallic cover; a bottom metallic cover attached to the top cover and providing a one-piece six-sided structure defining a cavity having an open first end for receiving a circuit board; and a second end bounded by an electrical connector attachable to the circuit board wherein the electrical connector includes a first side having an aperture having a receptacle contact mounted therein for receiving a contact pin of an external device and a second side having a PCB contact protruding transversely therefrom and electrically connected to the receptacle and the PCB contact having a wiping area spaced from the bottom metallic cover forming a gap in communication with the cavity for receiving an edge of the circuit board therein, the edge having conductive fingers thereon for slidingly engaging the wiping area of the PCB contact to carry electrical signals between the circuit board and the electrical connector.
Claim 2
Dependent Claim
159 words
A one-piece memory card assembly for housing a semi-conductor device comprising: a top metallic cover; a bottom metallic cover attached to the top cover and providing a one-piece six-sided structure defining a cavity having an open first end for receiving a circuit board; and a second end bounded by an electrical connector attachable to the circuit board wherein the electrical connector includes a first side having an aperture having a receptacle contact mounted therein for receiving a contact pin of an external device and a second side having a PCB contact protruding transversely therefrom and electrically connected to the receptacle and the PCB contact having a wiping area spaced from the bottom metallic cover forming a gap in communication with the cavity for receiving an edge of the circuit board therein, the edge having conductive fingers thereon for slidingly engaging the wiping area of the PCB contact to carry electrical signals between the circuit board and the electrical connector.
Claim 3
Dependent Claim
40 words
