This invention pertains to a high density interconnection test connector intended especially for verification of integrated circuits, including a plate supporting a multiplicity of conductive pins one of the ends of which forms a contact zone with the electronic circuit to be tested and the other end forms a contact zone with a connecting plate that has a connection means with the test equipment, with the conductive pins presenting a form that is capable of ensuring flexibility and including a longitudinal component, characterized in that the pins present a succession of at least three arc-shaped sections (4, 5, 6) in alternating directions extended on both sides by rectilinear segments that are mobile according to one degree of freedom in axial translation, with the pins being inserted in the front plates.
