Abstract
Abstract A card edge connector (10) includes an insulative housing (12) defining a card receiving central slot (14) for receiving a card (200) therein. Two rows of passageways (16) are respectively positioned by two sides of the central slot (14) for receiving a plurality of signal contacts (18) therein, respectively. A corresponding number of grounding contacts (20) are positioned in the same passageways (16) with the signal contacts (18), respectively, in a one-by-one relationship with the signal contact (18) wherein each grounding contact (20) is disposed in a lower and inner position in the corresponding passageway (16) in comparison with the signal contact (18) which shares the same passageway (16). A shorting bar or block (36) is inserted into the cavity (34) from the bottom and a series of grounding pins (42) are side by side arranged along the block (36) longitudinally whereby each grounding pin (42) has two opposite arms (46) for respective engagement with the corresponding pair of grounding contacts (20) positioned in the pair of passageways (16) in the same transverse plane and by two sides of the central slot (14). Each grounding pin (42) further includes a lead (48) extending downward toward the PC board (100) on which the connector (10) is mounted wherein the lead (48) is generally in the mid-position between two tails of the corresponding two signal contacts (18) sharing the same pair of opposite passageways (16) with such pair of grounding contacts (20).

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
115 words
A card edge connector comprising: an insulative housing defining a central slot and a central cavity, said central slot receiving a card and said central cavity receiving a shorting bar therein; two rows of passageways disposed by two sides of the central slot for respectively receiving a corresponding number of signal contacts therein; a corresponding number of grounding contacts respectively positioned in the passageways, each of said grounding contacts sharing one same passageway with one of the corresponding signal contacts; and a series of grounding pins disposed in the shorting bar wherein each of said grounding pins includes two arms respectively engaging one pair of grounding contacts which are laterally aligned with said grounding pin.
Claim 2
Dependent Claim
115 words
A card edge connector comprising: an insulative housing defining a central slot and a central cavity, said central slot receiving a card and said central cavity receiving a shorting bar therein; two rows of passageways disposed by two sides of the central slot for respectively receiving a corresponding number of signal contacts therein; a corresponding number of grounding contacts respectively positioned in the passageways, each of said grounding contacts sharing one same passageway with one of the corresponding signal contacts; and a series of grounding pins disposed in the shorting bar wherein each of said grounding pins includes two arms respectively engaging one pair of grounding contacts which are laterally aligned with said grounding pin.
Claim 3
Dependent Claim
34 words
The connector as defined in claim 1, wherein each pair of the signal contact and the grounding contact sharing with the same passageway are positioned at a high level and a low level, respectively.
Claim 4
Dependent Claim
34 words
The connector as defined in claim 1, wherein each pair of the signal contact and the grounding contact sharing with the same passageway are positioned on an outermost side and an innermost side, respectively.
Claim 5
Dependent Claim
39 words
The connector as defined in claim 1, wherein each pair of the signal contact and the grounding contact sharing with the same passageway have their own engagement sections at the distal ends for preloading consideration with the housing, respectively.
Claim 6
Dependent Claim
60 words
The connector as defined in claim 1, wherein grounding pins have leads extending downward out of a bottom surface of the shorting bar, and wherein said leads are arranged in a staggered manner and each of said leads is spaced, in a generally equal distance, from the corresponding pair of signal contacts which are aligned transversely with said grounding pin.
Claim 7
Dependent Claim
28 words
The connector as defined in claim 1, wherein a series of passages are disposed along a lengthwise direction of the shorting bar for receiving said grounding pins, respectively.
Claim 8
Dependent Claim
44 words
The connector as defined in claim 6, wherein corresponding to each of said passages, a first aperture and a second aperture are disposed thereabouts and communicate therewith for receiving a lead and a retention bar of the corresponding grounding pin in the passage, respectively.
Claim 9
Dependent Claim
30 words
The connector as defined in claim 7, wherein the lead is positioned adjacent one arm and the retention bar is positioned adjacent the other arm of the same grounding pin.
Claim 10
Dependent Claim
96 words
A card edge connector assembly comprising: an insulative housing defining a central slot for receiving a card therein; two rows of passageways disposed by two sides of the central slot for respectively receiving a corresponding number of signal contacts therein; a corresponding number of grounding contacts respectively positioned in the passageways, each of said grounding contacts sharing one same passageway with one of the corresponding signal contacts; and a shorting bar having a series of grounding pins therein whereby each of said grounding pins is engaged with and aligned with a corresponding pair of grounding contacts.
Claim 11
Dependent Claim
96 words
A card edge connector assembly comprising: an insulative housing defining a central slot for receiving a card therein; two rows of passageways disposed by two sides of the central slot for respectively receiving a corresponding number of signal contacts therein; a corresponding number of grounding contacts respectively positioned in the passageways, each of said grounding contacts sharing one same passageway with one of the corresponding signal contacts; and a shorting bar having a series of grounding pins therein whereby each of said grounding pins is engaged with and aligned with a corresponding pair of grounding contacts.
Claim 12
Dependent Claim
