Abstract

A female U-shaped electrical connector for staking to printed circuit boards capable of forming disconnect terminations between printed circuitry and a male tab (or blade) connector where the sides of the '"'"''"'"''"'"''"'"'U'"'"''"'"''"'"''"'"' are bowed inwardly to form a spring wipecontact with any tab connector inserted therebetween and where the female connector extends through the board and is clinched in position thereon without piercing the printed circuitry so as to bring the free ends of the '"'"''"'"''"'"''"'"'U'"'"''"'"''"'"''"'"' into positive electrical contact with the printed circuitry.

Claims

1. A female printed circuit tab connector comprising a generally U-shaped body made from a springlike conductive material, the sides of said U-shaped body each having a portion bent inwardly towards each other to define a restricted internal spacing for making a spring wipe contact with a tab inserted therebetween, the free ends of said U-shaped body forming flat members bent outwardly at substantially right angles to said body and said members having at least portions extending downwardly each in a nonpiercing relatively abrupt contact configuration, one portion being a dimple, another portion being ears bent downwardly at the opposing free sides of said member, gripping means for fixing said connector to a printed circuit board with said downwardly extending portion of said free ends being constructed and positioned relative to said gripping means to press into a positive engagement with at least one conductive surface of such a printed circuit board.

2. A connector as claimed in claim 1 wherein said gripping means is a tongue lanced out from each of said members long enough to extend through a printed circuit board and be securely clinched behind said board.

3. A connector as claimed in claim 2 further comprising four locking legs formed from each edge of the sides of said U-shaped body and being slightly outwardly sprung.

4. A female printed circuit tab connector comprising a generally U-shaped body made from a springlike conductive material, the sides of said U-shaped body each having a portion bent inwardly towards each other to define a restricted internal spacing for making a spring wipe contact with a tab inserted therebetween, the free ends of said U-shaped body forming flat members bent outwardly at substantially right angles to said body and said members having at least a portion extending downwardly in a nonpiercing relatively abrupt contact configuration, said downwardly extending portion of said members being an ear formed from a portion of said member bent downwardly, gripping means for fixing said connector to a printed circuit board with said downwardly extending portion of said free ends being constructed and positioned relative to said gripping means to press into a positive engagement with at least one conductive surface of such a printed circuit board.

5. A connector as claimed in claim 4 wherein said gripping means is a tongue lanced out from each of said members long enough to extend through a printed circuit board and be securely clinched behind said board.

6. A connector assembly comprising a female connector having a generally U-shaped body, the sides of said U-shaped body each having a portion bent inwardly towards each other to define opposed Internal contact areas for making a spring wipe contact with a male connector adapted to be inserted therebetween, a printed circuit board having a hole therethrough to accommodate the body of said female connector and smaller tongue holes spaced from said body hole sufficiently to assure a firm base therebetween, a conductive lamina affixed to one side of said board adjacent said holes, said U-shaped body extending through said hole, the free ends of said U-shaped body being formed outwardly with portions extending downwardly to engage said lamina in a nonpiercing relatively abrupt electrical contact configuration, and a tongue lanced out from each of said free ends extending through said tongue holes and clinched to the board on the side opposite said free ends to fix said female connector onto said board and press said downwardly extending portions into positive engagement with said lamina.

7. A connector as claimed in claim 6 wherein said downwardly extending portion is a dimple adjacent the joinder of each of said tongues to said free ends which forms a pressure contact with said lamina.

8. A connector as claimed in claim 6 wherein said free ends have portions of their edges bent downwardly forming spring contacts bearing against said lamina.

9. A connector as claimed in claim 7 wherein said free ends have portions of their edges bent downwardly forming spring contacts bearing against said lamina.
