There is disclosed a springy rolled metal pin such as a spirally rolled pin, the inner end portion of which is bent inwardly to form a springy tongue dividing the interior of the pin into two chambers. Upon insertion into one of the chambers of a wire of suitable diameter which may be part of an integrated circuit module, and subsequent insertion of the pin into a confining mounting hole, the wire is tightly held in the respective pin chamber by the lateral pressure of the tongue and the radial pressure exerted by the inner peripheral wall of the pin, said radial pressure being caused by the diametrical contraction experienced by the pin when inserted into the mounting hole. There is also disclosed a springy rolled two-part or double pin, the two parts of which have different diameters. When one part of such double pin is inserted into a confining mounting hole, the inserted pin part anchors itself in the hole due to its springiness while the protruding part retains its springiness and is available, for instance, as a springy male contact element for making connection with a tubular female contact element or with the foil conductors on printed circuit boards or with a tubular female. |
