An electrical connector for electrically interconnecting flat terminals known as tabs. The contact units are loosely positioned in a housing but yet preloaded to provide wiping action on the inserting tabs terminals. The spring members of the contact units provide two stage insertion forces with the first stage being a low force and the second stage substantially higher.

DETAILED DESCRIPTION What is claimed is: 1.
An electrical connector, comprising: a housing with a cavity therein and with a slot located in each of two opposing walls providing access to the cavity, one slot being parallel to and adjacent a top wall of the housing and the second slot being parallel to and adjacent a bottom wall of the housing; an elongated conductor having a convex surface at each end with one convex surface facing a direction opposite to that of the other convex surface; and a spring member attached to the conductor intermediate the ends thereof and having a spring blade with a convex surface extending from opposite surfaces of the conductor; said conductor and attached spring member being positioned in the cavity so that the convex surface on each end of the conductor and on each spring blade are in line with a slot and are adjacent respectively a top and bottom wall to form therewith first and second receptacles in line with each other for receiving a tab inserted into the slots and further with the spring blades bearing against said top or bottom walls to resiliently position and support the conductor and permit pivoting thereof about the point of attachment as said tabs engage said first receptacles.
2.
The electrical connector of claim 1 wherein the conductor includes a notch on each side intermediate the ends and the spring member includes a band which encircles the conductor and is received in the notches to prevent longitudinal movement along the conductor.
3.
The electrical connector of claim 2 wherein the conductor includes a concave surface adjacent each end and which face in opposite directions relative to each other, and the spring blades include a rounded midsection which is received in the concave surface when compressed.
4.
The electrical connector of claim 1 wherein the spring member is stamped from a resilient material with each blade being attached to an opposite side of an elongated strap and having an attachment section with one end being attached to the strap, an end section and a midsection intermediate to and wider than the attachment and end sections
