Abstract

The present invention relates to a circuit selection or programming device for a printed circuit board wherein a plurality of strap conductors are mounted on a dielectric substrate and provided with depending electrical leads for plugging into a printed circuit board. The strap conductors may be selectively punched out to provide an interrupted circuit condition. Alternatively the strap conductors may be selectively punched and formed to provide various types of electrical terminals to which may be connected electronic circuit components.

Claims

1. A method for providing a program of interruptable jumper connections across a plurality of spaced circuit paths on the flat surface of a circuit board, comprising the steps of:

embedding a plurality of normally electrically continuous conductors in a dielectric base,

each of said conductors being provided with a pair of integral lead portions projecting from opposite sides of said base,

bending said lead portion proximate said sides of said base to provide vertically depending electrical leads,

exposing portions of said conductors in corresponding recesses provided in said base,

dividing one or more selected exposed portions into respective spaced conductor portions subsequent to embedding said conductors in said base thereby electrically interrupting each said selected normally continuous conductor and thereby providing a selective program of conductors comprising only divided conductors on said base or a combination of divided and continuous conductors on said base,

mounting said dielectric base onto said flat surface of said circuit board,

electrically connecting corresponding electrical leads of said conductors to selected spaced circuit paths whereby each said continuous conductor of said selective program provides an electrically conductive jumper connection across corresponding selective spaced circuit paths and whereby each said divided conductor of said selective program is electrically interrupted to prevent a jumper connection across corresponding selected spaced circuit paths,

bending free end portions of said spaced conductor portions of at least one said divided conductor to project vertically upward from said base to provide spaced tab type electrical terminals defining therebetween an electrical component receiving space in vertical alignment with a corresponding recess.

2. A method for providing a program of interruptable jumper connections across a plurality of spaced circuit paths on the flat surface of a circuit board, comprising the steps of:

embedding a plurality of normally electrically continuous conductors in a dielectric base,

each of said conductors being provided with a pair of integral lead portions projecting from opposite sides of said base,

bending said lead portions proximate said sides of said base to provide vertically depending electrical leads,

exposing portions of said conductors in corresponding recesses provided in said base,

dividing one or more selected exposed portions into respective spaced conductor portions subsequent to embedding said conductors in said base thereby electrically interrupting each said selected normally continuous conductor and thereby providing a selective program of conductors comprising only divided conductors on said base or a combination of divided and continuous conductors on said base,

mounting said dielectric base onto said flat surface of said circuit board,

electrically connecting corresponding electrical leads of said conductors to selected spaced circuit paths whereby each said continuous conductor of said selective program provides an electrically conductive jumper connection across corresponding selective spaced circuit paths and whereby each said divided conductor of said selective program is electrically interrupted to prevent a jumper connection across corresponding selected spaced circuit paths,

forming a notch on each of said spaced conductor portions of at least one said divided conductor, and

bending said spaced conductor portions to project vertically upward from said base to provide a vertically projecting pair of notched tab type electrical terminals with their notches aligned, said terminals being spaced apart and defining therebetween an electrical component receiving space in vertical alignment with a corresponding recess.

3. In a circuit programming device for mounting on a circuit board, having a plurality of flat conductors embedded in a molded dielectric base, at least some of which conductors have portions which project outwardly of opposite sides of said base and are bent vertically downward to provide electrical leads depending from said base, the improvement comprising:

said conductors being elongated and normally continuous to provide an electrical circuit therealong,

said base having a plurality of elongated openings overlying corresponding normally continuous conductors and exposing portions of the same for individual selected division thereof whereby to interrupt a selected electrical circuit along a said individual conductor subsequent to embedding said conductors in said base,

one or more of said normally continuous conductors being individually divided into a pair of opposed flat tabs embedded in said base at opposite sides of a corresponding individual recess,

said opposed flat tabs being bent upwardly proximate said opposite sides of each said corresponding individual recess to provide vertically upward projecting pairs of flat contact surfaces at opposite ends of each said corresponding individual recess,

each pair of said flat contact surfaces facing each other and defining therebetween an electrical component receiving space,

each said corresponding individual recess defining a component receiving nest, whereby an electrical component electrically engaging a corresponding pair of said flat contact surfaces is received in a corresponding component receiving space and is at least partially received in a corresponding component receiving nest.

4. The structure as recited in claim 3, wherein, one or more selected pairs of said tabs are provided with aligned notches in said contact surfaces thereof, said notches communicating with free ends of said tabs to provide notched tab type terminals.
