Electricial connector with structure for reducing resonances

An electrical connector comprising:

• an insulative housing comprising two opposite elongate walls along a longitudinal direction, and an elongate slot between the two elongate walls in a lateral direction perpendicular to the longitudinal direction;
• a plurality of contacts located in each elongate wall of the housing and having pairs of differential-pair contacts, pairs of grounding contacts located at two opposite sides of each pair of differential-pair contacts;
• and a unitary grounding bar attached to each elongate wall of the housing;
• wherein the grounding bar comprises a plurality of lower spring fingers and a plurality of upper spring fingers, wherein in a vertical direction perpendicular to both the longitudinal direction and the lateral direction, the lower spring fingers contact lower portions of the grounding contact, respectively, while the upper spring fingers contact upper portions of the grounding contacts respectively, wherein two lower spring fingers at opposite sides of each pair of differential-pair contacts are linked with a lower transverse bar along the longitudinal direction, wherein two upper spring fingers at opposite sides of each pair of differential-pair contacts are linked with an upper transverse bar along the longitudinal direction, wherein the upper spring fingers extend from corresponding lower transverse bar.

An electrical connector comprising:

• an insulative housing including a pair of side walls extending along a longitudinal direction, and a receiving slot located between the pair of side walls in a lateral direction perpendicular to the longitudinal direction;
• a plurality of contacts retained in the housing and having grounding contacts and differential-pair contacts;
• and
• a unitary grounding bar attached to the housing and including:
• a pair lower spring fingers respectively contacting lower regions of contacting sections of the ground contacts in said lateral direction, and a pair of upper spring fingers respectively contacting upper regions of the contacting sections of the ground contacts in the lateral direction whereby each grounding contact has two contact points with the grounding bar;
• and
• a transverse base extending along the longitudinal direction and equipped with a retaining device to retain the grounding bar to the housing;
• wherein the lower spring fingers directly extend upwardly from the transverse base while the upper spring fingers indirectly extend from the transverse base via a lower transverse bar linked to at least one corresponding lower spring finger and extending in at least along said longitudinal direction.
