Abstract
An electrical connector includes a row of terminals (20) having a pair of differential signal terminals (21) mounted on a mating tongue (11). Each of the signal contact terminals has a rear end (211) on a back outer face of the connector and a free mounting end (213) away from the back outer face. The free mounting ends are located on a first end row and bent from the rear ends and away from each other in opposite transverse directions so as to widen a pitch therebetween to improve impendence for decreasing interference.
Claims16
An electrical connector, comprising:
- an insulative housing including a mating tongue exposed in a mating port, said mating tongue having a first surface exposed thereon;
- a row of contact terminals mounted on the mating tongue and at least including a pair of differential signal contact terminals adjacently disposed with each other and a pair of grounding/power contact terminals, the pair of differential signal contact terminals located between said grounding/power contact terminals, said grounding/power contact terminals and said signal contact terminals having respective grounding/power contact sections and signal contact sections mounted on the first surface of the mating tongues and equidistantly spaced along a row direction of said contact terminals;
- each of said differential signal contact terminals having a rear end on a back outer face of the insulative housing and a free distal end located away from said back outer face, said free distal ends located on a first end row and bent from said rear ends and away from each other in opposite transverse directions such that a transverse spacing distance between said adjacent free distal ends is larger than a transverse spacing distance between said adjacent rear ends.
An electrical connector, comprising:
- an insulative body having a mating tongue extending forwardly from a back wall of the insulative body;
- a plurality of contacts disposed on a surface of the mating tongue and equidistantly spaced from each other;
- said contacts at least including two type contacts, including:
- two first type contacts;
- and
- two second type contacts adjacently disposed with each other and located between the two first type contacts,
- said first type contacts having free tailing ends located in a first row, said second type contacts having free distal ends located in a second row different from the first row;
- and wherein
- said free distal ends are bent from said second type contacts and away from each other in two opposite transverse directions, while said free tailing ends are bent from said first type contacts in a first lengthwise direction perpendicular to one of the transverse directions relative to one adjacent second type contact.

An electrical connector comprising:
- an insulative housing defining a mating port for mating with a complementary connector and a mounting face for mounting to a printed circuit board;
- a plurality of differential pairs of signal contacts disposed in the housing, each of said differential pairs of signal contacts defining a mating contacting section exposed in the mating port and a mounting section exposed on the mounting face;
- and
- a plurality of grounding/power contacts disposed in the housing, each of the grounding/power contacts including a contacting portion exposed in the mating port and a mounting portion exposed on the mounting face;
- wherein
- the mating sections of the differential pairs of signal contacts and the mating portions of the grounding/power contacts are located in a first plane while the mounting sections of the differential pair of signal contacts are located in second plane while the mounting portions the grounding/power contacts are located in a third plane different from said second plane;
- wherein
- a pitch between the mating sections of the differential pair of signal contacts is smaller than that between the mounting sections of the same differential pair of the signal contacts.
