摘要:
A printed circuit board including a dielectric material having first and second major surfaces, a predetermined number of electrical conductors attached to the major surfaces, a plurality of slots in the board, the slots beginning at the free edge of the board and continuing inwardly for a predetermined length, a portion of the electrical conductors lying parallel and adjacent to a portion of the longitudinal axis of the slots on both of the major surfaces, and a "U" shaped current carrying connector inserted into one of the slots the terminal free edges thereof in mechanical engagement with a preselected conductor of the first surface and a preselected conductor of the second surface forming an electrical path there between.
