Card bus connector

Claim 2

A card bus connector for being mounted on a printed circuit board (PCB) having a plurality of grounding traces thereon, comprising; an insulative housing having a connecting portion and a pair of receiving arms extending from distal ends of the connecting portion, each receiving arm defining a guiding groove therein; a plurality of contact terminals received in passageways defined through the connecting portion; a metal strip received in each guiding groove of each receiving arm of the housing for contacting a metal cover of an inserted electrical card; and a grounding plate firmly positioned between the connecting portion and the receiving arms of the housing and electrically contacting said metal strips, the grounding plate having a front portion directly contacting the grounding traces of the printed circuit board thereby forming a grounding path which electrically connects the inserted electrical card to the grounding traces via said metal strips, the front portion of the grounding plate is located adjacent to an insertion entrance of the inserted electrical card in the connector and forms a number of grounding portions and a talon-like retaining portion along the front portion thereof the front portion of the grounding plate slopes downward and forms a curved edge which contacts the grounding traces of the printed circuit board the grounding plate is located between the inserted electrical card and the printed circuit board and the grounding portions contacting the grounding traces of the printed circuit board and retaining portions snugly engaging an edge of the printed circuit board for increasing the retention strength of the card bus connector thereon portions.

Claim 3

The card bus connector as described in claim 1, wherein the retaining portion of the grounding plate is U-shaped for snugly receiving the edge of the PCB.

Claim 4

The card bus connector as described in claim 1, wherein the retaining portion of the grounding plate is L-shaped for abutting against the edge of the PCB.

Claim 5

A card connector assembly, comprising: a printed circuit board with a plurality of first and second grounding traces formed thereon; and a card bus connector mounted on the printed circuit board, including: an insulative housing having a connecting portion and a pair of receiving arms extending from distal ends of the connecting portion, each receiving arms extending from distal ends of the connecting portion, each receiving arm defining a guidance groove therein; a plurality of contact terminals received in passageways defined through the connecting portion; at least a metal strip disposed within corresponding guiding groove of said housing for contacting metal covers of an inserted electrical card; a number of metal standoffs extending from a bottom surface of the housing and electrically connecting the first grounding traces of the printed circuit board and said metal strip thereby forming a first grounding path; and a grounding plate firmly positioned among the connecting portion and the pair of receiving arms of the housing and electrically contacting said at least one metal strip, the grounding plate having a front portion electrically connecting the second grounding traces of the printed circuit board with said at least one metal strip thereby forming a second grounding path, the front portion of the grounding plate directly contacts the number of metal standoffs and forms a number of grounding portions and a talon-like retaining portion along the front portion thereof, the grounding portions contacting the grounding traces of the printed circuit broad and a retaining portion snugly receiving an edge of the printed circuit board therein for increasing the retention strength of the card bus connection thereon the front portion of the grounding plate slopes downward and forms a curved edge which contacts the second grounding traces of the printed circuit board.

Claim 6

A card connector assembly, comprising: a printed circuit board with a plurality of first and second grounding traces formed thereon; and a card bus connector mounted on the printed circuit board, including: an insulative housing having a connecting portion and a pair of receiving arms extending from distal ends of the connecting portion, each receiving arms extending from distal ends of the connecting portion, each receiving arm defining a guidance groove therein; a plurality of contact terminals received in passageways defined through the connecting portion; at least a metal strip disposed within corresponding guiding groove of said housing for contacting metal covers of an inserted electrical card; a number of metal standoffs extending from a bottom surface of the housing and electrically connecting the first grounding traces of the printed circuit board and said metal strip thereby forming a first grounding path; and a grounding plate firmly positioned among the connecting portion and the pair of receiving arms of the housing and electrically contacting said at least one metal strip, the grounding plate having a front portion electrically connecting the second grounding traces of the printed circuit board with said at least one metal strip thereby forming a second grounding path, the front portion of the grounding plate directly contacts the number of metal standoffs and forms a number of grounding portions and a talon-like retaining portion along the front portion thereof, the grounding portions contacting the grounding traces of the printed circuit broad and a retaining portion snugly receiving an edge of the printed circuit board therein for increasing the retention strength of the card bus connection thereon the front portion of the grounding plate slopes downward and forms a curved edge which contacts the second grounding traces of the printed circuit board.

Claim 7

The card connector assembly as described in claim 4, wherein the retaining portion of the grounding plate is U-shaped for snugly receiving the edge of the PCB.

Claim 8

The card connector assembly as described in claim 4, wherein the retaining portion of the grounding plate is L-shaped for abutting against the edge of the PCB.
