Miniature matrix programming board

Claim 1

A matrix connector for selectively connecting a cross bar in a first series of parallel bars with a similar cross bar in a second series of parallel bars comprising: (a) an insulator block for supporting both series of parallel bars, formed with a plurality of spaced cylindrical holes connecting two plane surfaces and arranged in two orthogonal lines; (b) a first series of elongated conductive bars in parallel array, each bar in the first series including a strip of conductive material formed with alternate ridges and grooves along its longitudinal axis and including a plurality of depending cylindrical sockets having resilient clamping walls, said sockets positioned in one end of the cylindrical holes in the insulator block; (c) a second series of elongated conductive bars also in parallel array but perpendicular to the first series, each bar in the second series including a strip of conductive material formed with alternate grooves and ridges along its longitudinal axis and including a plurality of depending cylindrical sockets having resilient clamping walls, said sockets positioned in the other end of the cylindrical holes in the insulator block; (d) a first cover plate secured to one side of the insulator block for covering one series of cross bars, said cover plate formed with a plurality of holes positioned in alignment with the holes in the insulator block for the insertion of connecting pins; (e) a second cover plate secured to the other side of the insulator block for covering the second series of cross bars, said cover plate having a plurality of connecting pins removably connected thereto for making contact with a socket in each cross bar and for connection to an external circuit; and, (f) a plurality of conducting connecting pins for insertion through the holes in the first cover plate to make contact with a socket in the first series of bars and a socket in the second series of bars.
