A circuit card connector (20) utilizes flexible circuitry (64) and a card-engagement assembly (50) which applies a normal force to the contact pads (34) of the circuit card (30). The connector includes two opposing connector end portions (40) and a card-engagement assembly (50) extending therebetween, the card-engagement assembly (50) including two opposing spring members (53) which are seated upon a pair of fulcrums. The spring members (53) are spaced apart from each other on opposite sides of a centerline of a card-receiving slot (80) of the connector (20). The spring members (53) have lower leg portions (55) and upper contact arm portions (57). The leg portions (55) of the spring members (153) project into the card-receiving slot (80) such that an insertion edge (36) of the circuit card (30) will impinge thereupon and cause them to spread apart, which in turn, will cause the contact arm portions (57) of the spring members (53) to rotate around their associated fulcrums so that the contact arm portions (57) will contact and exert a normal force upon contact pads (34) located on opposing sides of the circuit card (30) near the circuit card insertion edge (36).

Connecteur de carte (20) faisant appel à des circuits flexibles (64) et à un ensemble de retenue de carte (50) qui applique une force normal aux contacts (34) de la carte (30). Le connecteur comprend deux parties d'extrémité opposées (40) et un ensemble de retenue de carte (50) inséré entre les deux et comprenant deux éléments élastiques (53) montés sur une paire de pivots. Les éléments élastiques (53) sont situés de part et d'autre de l'axe d'une fente d'insertion de carte (80) du connecteur (20). Les éléments élastiques (53) ont des parties de support inférieures (55) et des parties de contact supérieures (57). Les parties de support inférieures (55) des éléments élastiques (53) s'avancent dans la fente d'insertion de carte (80) de façon qu'un bord d'insertion (36) de la carte (30) entre en contact avec elles de façon à les écarter, ce qui fait pivoter les parties de contact supérieures (57) des éléments élastiques (53) de façon à exercer une force normale sur les contacts (34) situés de part et d'autre de la carte (30), près du bord d'insertion (36).
