Abstract

This small connector assembly involves a pin 10 of either round or rectangular cross section. Pin 10 is to be forced into wiping contact between the flexible fingers 11 of a contact formed of thin strip stock phosphor bronze. The stem 12 of the folded strip is projected through or molded into a circuit board 13 which can have conductor lines on either side and be dip soldered to the projecting stem. A series of barbs 14 are formed on the sides of the stem 12 inside board 13 to lock it in place.

Miniature Pluggable Contacts

This small connector assembly involves a pin 10 of either round or rectangular cross section. Pin 10 is to be forced into wiping contact between the flexible fingers 11 of a contact formed of thin strip stock phosphor bronze. The stem 12 of the folded strip is projected through or molded into a circuit board 13 which can have conductor lines on either side and be dip soldered to the projecting stem. A series of barbs 14 are formed on the sides of the stem 12 inside board 13 to lock it in place.

The particular shape of the fingers 11 are proportioned to maintain a suitable normal force for the assembly of small module cards containing either the pins or the contacts. The S-curve formations of fingers 11 are each produced by four successive similar radii. Such shape the strip material out of the stem 12 and into two opposing serpentine contact blades with enough flexure to embrace the inserted pin 10 with a constant force.

Board 13 can be a cable terminating holder in which contacts 11 are connected to many lines. Such an assembly can be plugged into a unit with projecting pins 10.
