Abstract: A board-to-board connector for mating with another connector has a housing and a plurality of terminals. The terminals and housing interact at a reference surface to accurately locate the terminals relative to the housing. The housing includes an elongated recess that extends parallel to a longitudinal axis of the housing and has a plurality of terminal receiving cavities spaced therealong. Each cavity includes a terminal retention wall with a reference surface on one side thereof and a terminal alignment opening extending from the cavity. Each terminals is disposed in a terminal receiving cavity. Each terminal includes a U-shaped retention portion, an L-shaped resilient contact portion extending from the U-shaped retention portion and has a contact projection thereon. A tail portion for interconnection to a circuit member is also provided.

Abstract: A board-to-board electrical connector assembly includes a first connector having a dielectric housing for mounting on a first printed circuit board for receiving a plug portion of a second connector mounted on a second printed circuit board. The connectors are mateable in a mating direction. A plurality of first conductive terminals are mounted on the housing of the first connector along the receptacle for engaging a plurality of second conductive terminals mounted along the plug portion of the second connector. A first retention member is mounted on one of the connectors and is engageable with a second retention member on the other connector in the mating direction. The first retention member includes a flexible engaging portion which extends in a direction generally perpendicular to the mating direction. The second retention member includes a rigid engaging portion for engaging and flexing the flexible engaging portion to hold the connectors in mated condition.
