Patent ID: 7588443

Claim:
A board-to-board electrical connector assembly for effecting a connection between two circuit boards, comprising: a first connector having a first generally rectangular insulative housing defining a pair of first longitudinal peripheral walls and a pair of first transverse peripheral walls connecting with the first longitudinal peripheral walls, the first longitudinal peripheral wall defining a rib in an inner portion thereof and the first transverse peripheral wall also defining a locking portion in an inner portion thereof; and a plurality of first terminals received in the first housing and each terminal defining a tail for connection to an appropriate circuit trace on the first circuit board and a contacting portion exposed generally at the first longitudinal peripheral wall; and a second connector having a second generally rectangular insulative housing defining a plurality of passageways at two opposite second longitudinal walls thereof; a plurality of second terminals received in corresponding passageways of the second housing and each defining a retaining portion secured in the passageway, a contacting portion for engaging with the contacting portion of the first terminal, a tail for connection to the second circuit board and a connection portion for connecting the retaining portion and the contacting portion of the second terminal, the connection portion defining a protrusion extending outwardly from a lateral side thereof; and a pair of metal ears engaged with two opposite transverse walls of the second housing and each defining a projection extending outwardly from a middle portion thereof; wherein the protrusion of the second terminal and the projection of the metal ear of the second connector are respectively snugly fit against the rib and the locking portion of the first connector.
