Electrical connector with improved high frequency signal transmission environment

An electrical connector, comprising:

• an insuilative housing defining a mating cavity with a mating tongue extending forwardly in a front-to-back direction;
• a plurality of contacts disposed in the housing and categorized with two pair of differential signal contacts commonly sandwiching a grounding contact therebetween so as to define an inner contact and an outer contact in each pair of differential signal contacts relative to the grounding contact, each of said contacts defining a front contacting portion for mating with a complementary connector, a rear soldering portion for mounting to a printed circuit board, a position portion and a connecting portion linked to each other and located between the front contacting portion and a rear soldering portion wherein the position portion is linked to the front contacting portion while the connecting portion is linked o the rear soldering portion;
• a first pitch among the contacting portions of all contacts along a transverse direction perpendicular to said front-to-back direction, keeps same while a second pitch among the soldering portions of all contacts varies wherein a first distance reflecting said second pitch between the soldering portion of the grounding contact and the neighboring pair of differential signal contacts is larger than a second distance reflecting said second pitch between the soldering portions of the respective neighboring pair of differential signal contacts internally;
• a third pitch among the connecting portions of all contacts varies compliantly corresponding to the soldering portions wherein a third distance reflecting said third pitch between the connecting portion of the grounding contact and that of the neighboring pair of differential signal contacts is larger than a fourth distance reflecting said third pitch between the connecting portions of the respective neighboring pair of differential signal contacts;
• wherein
• the third distance is larger than the first distance so as to enlarge a fifth distance between the connecting portions of the two corresponding inner contacts of the two pairs of differential signal contacts.

An electrical connector, comprising:

• an insulative housing defining a first receiving cavity with a first tongue extending thereinto, the first tongue being assisted by a base portion of the insulative housing, the base portion having a bottom wall in a bottom side of the insulative housing, the base portion forming at least one mounting portions protruding downwardly from the bottom wall and forming a mounting surface on the bottom side of the mounting portion;
• a plurality of first contacts being equipped with a first grounding contact and two pairs of differential signal contacts at two sides of said first grounding contact, each first contact having a contacting portion disposed in a same row along a transverse direction of a mating surface of the first tongue, a soldering portion extending downwardly beyond the mounting surface, a horizontal position portion extending rearwardly from the contacting portion and a connecting portion between the position portion and the soldering portion;
• and
• wherein a width of the connecting portion of the first grounding contact is wider than that all of the connecting portions of the other first contacts, and the connecting portion of the first grounding contact further has a strengthen portion at a bottom thereof, which extends beyond the bottom wall and extending to the mounting surface, a width of the strengthen portion is wider than that of the soldering portion of each contact.
