ABSTRACT:
An electrical connection device, particularly but not exclusively for printed circuit boards, consists of a rigid insulating support for receiving a board, resilient contact members each having one end fixed relative to the support and adapted to engage resiliently, through an active region of the contact member, a respective one of a number of conductive connection tracks on the board, and a control mechanism operable alternately to open and close the contact members to allow insertion and extraction of the board. The control mechanism comprises at least one slide movable in the rigid support and each contact member comprises, between a portion forming a hinge and a movable end held or joined in fixed position in the slide, two substantially rectilinear portions which are inclined to one another and to the direction of translation of the slide and which are guided transversely by the slide, the junction of the two portions forming the active region of the contact member.
