ABSTRACT:
A matrix pin board has a plurality of transversely and longitudinally extending I-shaped elements with the flanges having a plurality of semicircular recesses spaced at intervals along the edges thereof. The I-shaped elements are side by side to form two insulating plates with channels therethrough and the flanges abutting to define holes at the recesses therein. The bottom flanges of the uppermost elements have a plurality of T-shaped transverse recesses therein at spaced intervals therealong, and the top flanges on the lowermost I-shaped elements extend through the T-shaped recesses. The holes defined by the flanges of the elements are aligned in vertical lines extending through the channels. The elements are held in engaged relationship and conductor elements extend along the channels having holes therethrough aligned with the vertically aligned holes and individual contact portions adjacent each of the holes, and terminal means are electrically connected to each of the conductor elements and extending to a point outside of the board. Pin elements can be inserted into the aligned holes for electrically connecting the conductor element in one of the uppermost channels with the conductor element in one of the lowermost channels.
