Abstract
Abstract The tool includes a holding mechanism which prevents the deformation of a wire inserted therein along a first crosssectional axis of the wire, and the tool further includes two shearing blades lying in separate planes which are parallel to the horizontal axis of the wire. These blades are moved into the wire thereby deforming it along its second cross-sectional axis into two bowed portions. The resulting connector is suitable both for making electrical connection to a cylindrical receiving portion, such as the through holes of a printed circuit board, and for holding components and wires in place prior to being flow soldered thereto.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
243 words
Apparatus for forming a wire into a connector suitable for mating with an aperture, the connector being comprised of first and second portions which are bowed in opposite directions and which are affixed to each other at each end thereof, such apparatus including in combination: holding means adapted to be positioned in an abutting relationship to the circumference of a wire for preventing extension of the wire along a first axis of the cross section thereof; first shearing means having a first curved portion on the periphery thereof for engaging the wire; second shearing means having a second curved portion on the periphery thereof for engaging the wire; said first and second curved portions being diametrically located with respect to each other on opposite sides and intermediate the ends of said wire; first driving means connected to said first shearing means; means guiding the motion of said first driving means so that said first and second shearing means are relatively movable toward each other only in substantially opposite directions along a second axis of the cross section of the wire which is perpendicular to said first axis; said first driving means moving said first shearing means relative to said second shearing means along said second axis into the wire so that said first and second curved portions offset the shape of the wire intermediate the ends and along said second crosssectional axis of the wire to form the bowed portions of the connector.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
21 words
The apparatus of claim 1, wherein said means guiding the motion of said first driving means is a first track means.
Claim 4
Dependent Claim
50 words
The apparatus of claim 2, further including: second driving means connected to said second shearing means, second track means guiding the motion of said second driving means so that said first and second shearing means are relatively movable toward each other relative to said holding means along a rectilinear path.
Claim 5
Dependent Claim
65 words
The apparatus of claim 1, wherein said first and second curved portions of said first and second shearing means lie in planes parallel to the plane of the longitudinal axis of the wire, said first and second shearing means being movable a predetermined distance with respect to each other into the wire from opposite direction along said second cross-sectional axis by said first driving means.
Claim 6
Dependent Claim
96 words
The apparatus of claim 4, wherein said first and second curved portions are moved a predetermined distance, which is greater than the radius of the wire into the wire to form the first and second connector portions, and thereby offsetting the shape thereof to cause the first and second connector portions to separate at a first point along the longitudinal axis of the wire and enabling the first and second connector portions to remain affixed at second and third points along the longitudinal axis of wire which are located on each side of said first point.
Claim 7
Dependent Claim
53 words
The The apparatus of claim 1, wherein said first and second curved portions are moved a predetermined distance into the wire which is less than the radius of the wire thereby offsetting the shape thereof to form the first and second connector portions without causing the first and second connector portions to separate.
