Abstract: A solderless electrical contact comprising a thin resilient flat plate having at least one pair of parallel extended legs defining an open-ended wire-receiving slot, and a method for making the contact. The legs of the contact are similarly coined along the wire-receiving slot, the coining being progressively deeper into the thickness of the flat plate from the open end of the slot toward the closed end thereof to taper the slot from a width adjacent the open end of the slot of less than the thickness of the flat plate to a lesser width adjacent the closed end of the slot. The contact permits effective electrical connection to two small diameter insulated conductors pressed into the wire-receiving slot.

Abstract: A connector having an insulating body formed with a plurality of parallel wire support channels, each of the channels being formed with a transverse step defining upper and lower wire support levels. The adjacent channels are formed with steps rising in opposite directions to position a lower wire support level between two upper wire support levels. A bifurcate spring compression reserve contact element extends through an aperture in each of the lower wire support levels and a cover formed with channels complementary to those on the body is retained on the body to support, retain and make electrical connection to wires in the channels.
