Abstract
Abstract A one-piece boardlock formed from an elongated metallic strip comprises a vertical mounting portion, and an integral horizontal portion extending from one end of the vertical portion. At the end of the horizontal portion remote from the vertical portion a pair of side legs are formed from two laterally spaced side portions by three successive right-angle bends so that the side legs project perpendicularly from the strip. Similarly, a pair of auxiliary legs are formed from an intermediate portion of the horizontal strip portion by stamping and bending. These four legs are positioned symmetrically around a central axis perpendicular to the horizontal strip portion. An outwardly inclined cam surface is provided adjacent each leg end, and an inwardly inclined cam surface is positioned intermediate the outwardly inclined cam surface and each leg end. Such four outwardly inclined cam surfaces are located almost at the same height so that equivalent symmetrical forces act on the edge of a mounting aperture in the board when the connector and the board are combined together.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
181 words
A boardlock for a connector comprising: a metallic strip having a vertical portion adapted for fastening to the connector; an integral horizontal portion extending perpendicularly from the vertical portion and adapted to overlie an adjacent parallel portion of the connector; at least a pair of laterally spaced side legs formed from laterally spaced portions of the horizontal portion bent perpendicularly out of the plane of said horizontal portion, said side legs lying in a plane perpendicular to the longitudinal dimension of said metallic strip; at least a pair of auxiliary legs formed from portions of the horizontal portion intermediate said laterally spaced portions and bent perpendicularly out of the plane of said horizontal portion, said pair of auxiliary legs being spaced apart in the direction of said longitudinal dimension and lying in a median plane including said longitudinal dimension; and an upper outwardly inclined cam surface and a lower inwardly inclined cam surface formed on each leg, said legs of said pairs of legs being equally spaced circumferentially about a central axis perpendicular to said horizontal portion of said metallic strip.
Claim 2
Dependent Claim
181 words
A boardlock for a connector comprising: a metallic strip having a vertical portion adapted for fastening to the connector; an integral horizontal portion extending perpendicularly from the vertical portion and adapted to overlie an adjacent parallel portion of the connector; at least a pair of laterally spaced side legs formed from laterally spaced portions of the horizontal portion bent perpendicularly out of the plane of said horizontal portion, said side legs lying in a plane perpendicular to the longitudinal dimension of said metallic strip; at least a pair of auxiliary legs formed from portions of the horizontal portion intermediate said laterally spaced portions and bent perpendicularly out of the plane of said horizontal portion, said pair of auxiliary legs being spaced apart in the direction of said longitudinal dimension and lying in a median plane including said longitudinal dimension; and an upper outwardly inclined cam surface and a lower inwardly inclined cam surface formed on each leg, said legs of said pairs of legs being equally spaced circumferentially about a central axis perpendicular to said horizontal portion of said metallic strip.
Claim 3
Dependent Claim
39 words
The boardlock for the connector according to claim 1, wherein each side leg is formed by three right angle bends to provide three integral leg sections, at least two of said sections constituting a grounding means for said boardlock.
Claim 4
Dependent Claim
28 words
The boardlock of the connector according to claim 2, wherein said side and auxiliary legs include outwardly inclined camming surfaces at a common height from said horizontal portion.
Claim 5
Dependent Claim
54 words
The boardlock of the connector according to claims 2, wherein one of said grounding means includes a surface portion of a reentrant section of each side leg lying spaced from and parallel to said horizontal portion, and the other grounding means includes upper outwardly inclined camming surfaces formed on said laterally spaced side legs.
Claim 6
Dependent Claim
100 words
A boardlock for a connector comprising a metallic strip having a vertical portion adapted for fastening to the connector; an integral horizontal portion extending perpendicularly from the vertical portion and adapted to overlie an adjacent parallel portion of the connector; the improvement comprising: at least three legs extending from the horizontal portion, at least one of said legs being formed by three right angle bends to provide three integral leg sections among which two of said sections constitute a grounding means for said boardlock, at least two of said legs including outwardly inclined camming surfaces and inwardly inclined camming surfaces.
Claim 7
Dependent Claim
100 words
A boardlock for a connector comprising a metallic strip having a vertical portion adapted for fastening to the connector; an integral horizontal portion extending perpendicularly from the vertical portion and adapted to overlie an adjacent parallel portion of the connector; the improvement comprising: at least three legs extending from the horizontal portion, at least one of said legs being formed by three right angle bends to provide three integral leg sections among which two of said sections constitute a grounding means for said boardlock, at least two of said legs including outwardly inclined camming surfaces and inwardly inclined camming surfaces.
