Abstract
Electrical connectors are described. More particularly, electrical connectors including a plurality of contacts are described. Both connector plugs and sockets are described. Electrical connectors that are suitable for mounting on a printed circuit board and electrical connectors that include a printed circuit board are described.
Claims8
An electrical connector comprising:
- a unitary housing elongated along a horizontal direction perpendicular to a mating direction of the connector, the unitary housing comprising an elongated base, opposing end walls and opposing top and bottom walls extending forwardly from the base along the mating direction and defining first and second L-shaped central slots therebetween separated by a middle wall, each L-shaped central slot comprising a longer horizontal slot portion and a shorter vertical slot portion adjacent the middle wall;
- a plurality of spaced apart contacts oriented along the mating direction, each contact comprising:
- a flexible contact member disposed in a corresponding passageway formed in a top wall of the longer horizontal slot portions of the first and second central slots for making contact with a corresponding contact of a mating connector;
- a retaining member extending from the flexible contact member and secured in the top wall;
- and
- a mounting member extending downwardly from the retaining member along a back surface of the base for mounting on a printed circuit board;
- and
- a plurality of spaced apart parallel co-planar protrusions extending rearwardly from a bottom of the backside of the elongated base, a portion of the mounting member of each contact being disposed between two neighboring protrusions.

An elongated electrical connector for mounting on a printed circuit board and mating with a mating connector along a mating direction, the connector comprising:
- an elongated base extending along a longitudinal direction perpendicular to the mating direction;
- first and second end walls extending forwardly along the mating direction from opposite longitudinal ends of the base;
- a bottom tongue extending forwardly along the mating direction from the base and disposed between and spaced apart from the first and second end walls, the bottom tongue having a uniform thickness along its length along the longitudinal direction and comprising first and second bottom tongue portions separated by a third bottom tongue portion;
- a top tongue having a front portion extending forwardly along the mating direction from the base and a rear portion extending rearwardly along the mating direction from the base, the top tongue disposed between and spaced apart from the first and second end walls, the top tongue having a uniform thickness along its length along the longitudinal direction and being spaced apart from the bottom tongue along a thickness direction perpendicular to the mating and longitudinal directions, a bottom surface of the front portion of the top tongue facing a top face of the third bottom tongue portion;
- a plurality of spaced apart first contacts disposed on a top surface of the first bottom tongue portion;
- a plurality of spaced apart second contacts disposed on a top surface of the second bottom tongue portion;
- a plurality of spaced apart third contacts disposed on a bottom surface of the bottom tongue;
- and
- a plurality of spaced apart fourth contacts, each fourth contact comprising:
- a front member extending along the mating direction and disposed in a corresponding passageway formed on a top surface of the front portion of the top tongue for making contact with a corresponding contact of a mating connector;
- a rear member extending from rear portion of the top tongue for mounting on a printed circuit board;
- and
- a middle member joining the front and rear members and being embedded in the rear portion of the top tongue.
