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.

Abstract
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.

9. An electrical connector, comprising:
-
a. a housing of insulating material with slots in opposing end walls accessing a cavity within the housing, said slots being offset relative to each other; and b. a contact unit positioned in the cavity and having an elongated conductor with a convex surface on each end and facing in opposing directions, and a spring member attached to the conductor between the ends thereof, said spring member including a strap and generally oval-shaped spring blades attached to said strap and extending away from opposite surfaces of the conductor, said spring blades including an attachment section with one end attached to said strap, an end section and a midsection intermediate the attachment and end sections, said contact unit disposed in the cavity with each convex surface forming a receptacle in cooperation with an adjacent wall which is perpendicular to the end walls, each receptacle being in alignment with a slot through which a tab may pass, and with the spring blades being biased against an adjacent wall to position and support the conductor in the cavity and to preload the convex surfaces against the adjacent walls so that upon insertion of tabs therebetween, wiping between the tabs and convex surfaces occurs. - View Dependent Claims (10, 11, 12, 13, 14)

15. An electrical connector for electrically interconnecting tabs inserted thereinto from opposite sides, said connector comprising:
-
dielectric housing means having walls defining an enclosed cavity and with slots through each of two opposing side walls accessing said cavity, one of said slots being parallel to and adjacent a top wall of said housing means and the second slot being parallel to and adjacent a bottom wall of said housing means; conductor means having a generally S-shape to define concavo-convex free ends, said conductor means pivotally disposed in said cavity with convex surfaces on said free ends facing respective top and bottom walls and defining in cooperation therewith first receptacle means in registration with a respective slot for receiving tabs inserted therethrough; and spring means having concavo-convex spring blades attached to and extending in opposite directions from an intermediate member, said intermediate member being attached to said conductor means with each spring blade adjacent a concave surface on said conductor means and with the convex surfaces on said spring blades being against respective top and bottom walls to position and support said conductor means in said cavity and for preloading said convex surfaces on said conductor means against respective top and bottom walls. - View Dependent Claims (16)
