Abstract:
An electrical connector (200) for connecting a daughter board (30) to a mother board, comprising:an insulation housing (221) to be mounted on said mother board and having a slot (225) for receiving said daughter board and a pair of front and rear rows of terminal receiving apertures (226B, 226A); anda plurality of short and long contact terminals (500, 400) provided in said front and rear terminal receiving aperture, respectively, and having lower and upper contact sections (519, 417), respectively, such that a vertical distance between said lower and upper contact sections is reduced after said daughter board is rotated rearwardly so that the moment of rotation upon said daughter board caused by said vertical distance is minimized, whereinsaid short contact terminal (500) has a vertical section (511) extending upwardly along a front wall (251) of said insulation housing up to substantially a half height of said front wall, a first curved section (513) extending downwardly from said vertical section (511), a second curved section (515) extending upwardly from said first curved section and curved with an acute angle and said lower contact section (519) extending from said curved section such that said lower contact section is turned counterclockwise at a top end (512) of said vertical section (511) of said short contact terminal when said daughter board is rotated rearwardly, andsaid long contact terminal (400) has a vertical section (411) extending upwardly along a rear wall (252) of said insulation housing up to substantially the same height of said rear wall, an inverted U-shaped section (413) extending from said vertical section (411) and curved with an acute angle and said upper contact section (417) extending from the curved contact section (415) such that said upper contact section is turned counterclockwise at a top end (412) of said vertical section of said upper contact terminal when said daughter board is rotated rearwardly, thus reducing said vertical distance between said lower and upper contact sections.
