Abstract

Abstract Electronic circuits are fabricated on circuit boards of the type on which components are mounted with leads extending generally perpendicular to and away from the board. The leads are latched under projections extending from pairs of pins. This positively locks the components in place during dip soldering. Each pin is an elongated one-piece thin metal sheet member having tabs extending from the terminal portion. The member is formed into a U-shape so that the tabs extend from the pin to form the projection under which the leads can be latched.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 181 words
In a pin for an electronic circuit board of the type on which components are mounted with one portion thereof parallel to said board and with leads thereof extending generally perpendicular to and away from said board and extending longitudinally to a plurality of pins mounted perpendicular to said board, each pin comprising: an elongated, one-piece, thin metal sheet member having an anchoring portion of parallelogram cross-section insertable in said board for supporting said pin in said board and a terminal portion extending from one end of said anchoring portion; said terminal portion having spaced non-connected tabs extending laterally of the longitudinal axis thereof; only said terminal portion being bent in generally U-shaped cross-section so that each of said tabs projects from said terminal portion and is substantially spaced longitudinally along said pin from said anchoring portion and each of said tabs is separate from each other and each forms a separate latch in spaced relationship from said board under which latches a lead of a component can be inserted to positively lock said component between said latches and said board.
Claim 2
Dependent Claim 181 words
In a pin for an electronic circuit board of the type on which components are mounted with one portion thereof parallel to said board and with leads thereof extending generally perpendicular to and away from said board and extending longitudinally to a plurality of pins mounted perpendicular to said board, each pin comprising: an elongated, one-piece, thin metal sheet member having an anchoring portion of parallelogram cross-section insertable in said board for supporting said pin in said board and a terminal portion extending from one end of said anchoring portion; said terminal portion having spaced non-connected tabs extending laterally of the longitudinal axis thereof; only said terminal portion being bent in generally U-shaped cross-section so that each of said tabs projects from said terminal portion and is substantially spaced longitudinally along said pin from said anchoring portion and each of said tabs is separate from each other and each forms a separate latch in spaced relationship from said board under which latches a lead of a component can be inserted to positively lock said component between said latches and said board.
Claim 3
Dependent Claim 44 words
The pin as recited in claim 1, wherein said terminal portion U-shaped cross-section defines a channel extending along the longitudinal axis thereof to aid solder flow therealong for solder connection of said terminal portion to a lead of a component mounted on said board.
