ABSTRACT:
The invention relates to apparatus for clamping superimposed conductive elements (11, 13) disposed in aligned groups by means of a clip device (22, 23) such that an integrated circuit device may be removably connected to a printed circuit card with a predetermined force being applied uniformly across all the superimposed elements. In accordance with the invention, at least one of the clips (22, 23), in the free state, has a cambered form, equivalent to the elastic deformation of an initially straight beam of uniform section and of the same length mounted on two simple supports spaced this length and uniformly charged over this length.
The invention is primarily used for the electrical interconnection of integrated circuit devices to printed circuit cards.
