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).
