Abstract: A plug connector (2) for an IC module (30) comprises clamping means (6), which act like a toggle joint and are adapted to clamp contact tabs (28) of the IC module (30) in a connector body (4). To define the depth to which the IC module (30) can be inserted and to position the IC module in parallel alignment with the connector body (4), backing elements (36, 46, 48, 50, 52) are provided and the clamping means (6) are so designed adjacent to their pivotal connection (20) that a plane (64) which is parallel to the connector body (4) is defined by at least two edges. Besides, the pivotal connection between the two clamping plates which constitute the clamping means consists of a positive hinge.

Abstract: A socket for dual-in-line components has two plates placed on top of the socket body between the rows of pin contact sockets. The plates are hinged together for a folding motion with the effect of a toggle lever for shutting the pin sockets on to the pins of the component and gripping them. The plates may be folded from an undone position down through a clamping position in which they are generally coplanar and then further into a position of stable equilibrium.
