Abstract 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.
A connector assemblage comprising in combination: a generallY cylindrical sleeve for insertion into a confining mounting hole in a support, said sleeve constituting a receiving contact member of the assemblage and being formed of a spirally rolled springy metal strip having several convolutes in engagement with each other at adjacent surfaces, the inner end of said strip protruding inwardly to form an elastic tongue extending substantially crosswise within the sleeve, said tongue defining two chambers within the sleeve along the length thereof, said sleeve having extending inwardly from one of its ends a notch for accommodating therein a bent-off elongate member inserted into the sleeve; and a wire conductor insertable into either one of said chambers and having a peripheral outline engaging an inner wall portion of the sleeve and a wall portion of the tongue with pressure contact upon insertion of the conductor into said one chamber, said wire conductor constituting an engaging contact member of the assemblage.

26 words
The connector assemblage according to claim 1 wherein said tongue has a substantially S-shaped cross section and terminates short of the inner wall of the sleeve.
Claim 4
Dependent Claim
100 words
A hollow generally cylindrical pin for insertion into confining mounting holes in support members, said pin having two lengthwise contiguous independently springy rolled parts of different diameter, either one of said parts being adapted to be inserted into a confining mounting hole of a support member, one of said pin parts being rolled tighter than the other whereby upon insertion of the pin parts into the mounting holes of two support members the tighter rolled pin part is retained in the respective one of said members with a stronger retention force than the other pin part in the other member.
Claim 5
Dependent Claim
100 words
A hollow generally cylindrical pin for insertion into confining mounting holes in support members, said pin having two lengthwise contiguous independently springy rolled parts of different diameter, either one of said parts being adapted to be inserted into a confining mounting hole of a support member, one of said pin parts being rolled tighter than the other whereby upon insertion of the pin parts into the mounting holes of two support members the tighter rolled pin part is retained in the respective one of said members with a stronger retention force than the other pin part in the other member.
Claim 6
Dependent Claim
