Abstract
Abstract The lead configuration of an electrical component is such that one of the leads locks into position in an aperture of a wiring board when the unit is inserted therein with nominal pressure. This configuration allows the unit to slide only so far into the aperture before it locks in place, thereby prohibiting the unit from being inserted any further, or from falling out of position if the board were inverted. These units remain locked in an upright position on the wiring board for the purpose of being further secured thereon, as by wave soldering.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
115 words
A lead configuration for an electrical component that mounts and locks in a printed circuit board aperture comprising an electrical component having at least one lead wire extending therefrom, said lead wire at a point spaced from said component having a first bend upwardly back toward said component through an angle of approximately 150* to a point where a second bend through an angle of approximately 70* causes the end portion of the wire to cross over the upper portion of said lead wire, thereby forming a generally triangular configuration which is substantially wider at said second bend than the width of an aperture in a printed circuit board to provide a locking action therein.
Claim 2
Dependent Claim
115 words
A lead configuration for an electrical component that mounts and locks in a printed circuit board aperture comprising an electrical component having at least one lead wire extending therefrom, said lead wire at a point spaced from said component having a first bend upwardly back toward said component through an angle of approximately 150* to a point where a second bend through an angle of approximately 70* causes the end portion of the wire to cross over the upper portion of said lead wire, thereby forming a generally triangular configuration which is substantially wider at said second bend than the width of an aperture in a printed circuit board to provide a locking action therein.
Claim 3
Dependent Claim
39 words
The lead configuration of claim 1 wherein said component has a second substantially straight and shorter lead wire extending thereform; said first bend being at a point that is substantially equal to the length of said second lead wire.
Claim 4
Dependent Claim
90 words
The lead configuration of claim 2 wherein said second lead wire has a bend outward from said at least one lead wire through an angle of approximately 90*, and then a bend back so as to follow its original track and to be approximately parallel therewith; and said at least one lead wire has a preliminary bend outward through an angle of approximately 90*, and then a bend back so as to follow its original track and to be substantially parallel therewith above said first and said second bends thereon.
Claim 5
Dependent Claim
68 words
The lead configuration of claim 2 wherein said at least one lead wire is swaged in the area that has said first bend through an angle of approximately 150*, and said at least one lead wire has a small notch at said second bend of approximately 70*, said notch being of a shape that will fit Into the lower corner of an aperture in a printed circuit board.
Claim 6
Dependent Claim
99 words
The lead configuration of claim 2 wherein said at least one lead wire is an anode lead wire for said component; and said second lead wire is a cathode lead wire of said component. 6.The lead configuration of claim 5 wherein the diameter across said lead configuration of said anode lead wire at its widest point is at least approximately 0.0180 inch wider than an anode aperture on a printed circuit board into which said configuration is inserted, said cathode lead wire being inserted into a cathode aperture on said printed board that is narrower than said anode aperture.
