Abstract
An electrical connector may include a first connector with electrically-conductive contacts. The contacts may have blade-shaped mating ends, and may be arranged in a centerline. The electrical connector may include a second connector with electrically-conductive receptacle contacts, which may also be arranged in a centerline. The connectors may be mated such that the mating portion of a first contact in the second connector may physically contact of a corresponding blade-shaped mating end of a contact in the first connector.
Claims24
An electrical connector comprising:
- a plurality of electrically isolated electrical contacts arranged at least partially coincident along a common centerline, wherein at least two of the plurality of electrically isolated electrical contacts each define a mating end that deflects in a first direction transverse to the common centerline by corresponding blade contacts of a mating connector and at least one of the plurality of electrically isolated electrical contacts is adjacent to one of the at least two of the plurality of electrically isolated electrical contacts and defines a respective mating end deflects in a second direction transverse to the common centerline and opposite to the first direction by a corresponding blade contact of the mating connector.
An electrical connector comprising:
- an array of electrical contacts with adjacent electrical contacts in the array paired into differential signal pairs along respective centerlines, the differential signal pairs separated from each other along the respective centerlines by a ground contact,
- wherein the electrical connector is devoid of metallic plates and comprises more than eighty-two differential signal pairs per inch of card edge, one of the more than eight-two differential signal pairs is a victim differential signal pair, and differential signals with rise times of 70 picoseconds in eight aggressor differential signal pairs closest in distance to the victim differential signal pair produce no more than six percent worst-case, multi-active cross talk on the victim differential signal pair.
An electrical connector, comprising:
- a first electrical contact and a second electrical contact positioned at least partially along a first centerline, the first electrical contact adjacent to the second electrical contact, wherein the first electrical contact defines a tail end that jogs in a first direction away from the first centerline and the second electrical contact defines a tail end that jogs in a second direction opposite the first direction;
- and
- a third electrical contact and a fourth electrical contact positioned at least partially along a second centerline that is adjacent to the first centerline, the third electrical contact adjacent to the fourth electrical contact, wherein the third electrical contact defines a tail end that jogs in a second direction and the fourth electrical contact defines a tail end that jogs in the first direction,
- wherein the tail ends of the first and second electrical contacts are in an orientation that is the mirror image of the tail ends of the third and fourth electrical contacts.

A substrate comprising:
- a first electrical via and a second electrical via positioned at least partially along a first centerline, the first electrical via adjacent to the second electrical via, wherein the first electrical via jogs in a first direction away from the first centerline and the second electrical via jogs in a second direction opposite the first direction;
- and
- a third electrical via and a fourth electrical via positioned at least partially along a second centerline that is adjacent to the first centerline, the third electrical via adjacent to the fourth electrical via, wherein the third electrical via jogs in a second direction and the fourth electrical via jogs in the first direction,
- wherein the first and second electrical vias are in an orientation that is a mirror image of third and fourth electrical vias.
1 more element
An electrical connector comprising:
- a differential signal pair comprising a first electrical contact retained in a dielectric housing and a second electrical contact retained in the housing adjacent to the first signal contact,
- wherein (i) the first electrical contact has a first length in the first direction, (ii) the second signal contact has a second length in the first direction, (iii) the first length being less than the second length, and (iv) an electrical signal in the second signal contact propagates through the second length longer than the electrical signal in the first signal contact propagates through the first length to correct skew from a mating differential signal pair in a mating right angle connector.
