With a radius of curvature R 336 of 2.29 inches and a mating conductor 306 width W 309 of 0.50 inches, for example, the total height 311 of the arc would only be about 0.014 inches, i.e., the contact mating surface 308 is nearly flat. [0113] Load balancing is an issue with multi-contact electrical connectors, and particularly so with multi-contact electrical power connectors.
