Abstract
Abstract An electrical matrix board of dielectric material having a printed circuit defined upon two surfaces thereof and including a plurality of metallic terminals defined thereon in a plurality of sets, the terminals being related such that each set includes a central terminal surrounded by secondary terminals arranged in a hexagonal configuration, and the distance between adjacent secondary terminals defining a set, and between such secondary terminals and the associated primary terminal being equal. The terminals include connection means, preferably in the form of an axial passage, a portion of which may be threaded to receive a screw connector. The terminal sets are arranged on the matrix board in groups, whereby a printed circuit interconnects the primary terminals of sets in different groups, and selected terminals of sets within the same group are also interconnected by a printed circuit. Bridge means permits interconnection of selected terminals within the same set or group and the printed circuits include taps disposed adjacent the edge of the matrix board for connecting the board into other circuitry.
