Abstract
A coupling plate with a plurality of electric coupling points comprises, in a preferred embodiment, a pair of plane plates (10, 12), between which there is provided an electrically insulating carrier layer (11), on which a pattern of electrically conducting areas (21-26) is provided. In the preferred embodiment, an electric coupling point is provided for each mechanical coupling stud (15) projecting from the upper side of the top plate (10). The studs (15) are hollow and flush with projections (19) on the lower plate (12) so that punched parts of the electrically conducting areas (20, 22, 24, 26) are just moved into the hollow coupling studs by means of the projections (19) on the lower plate (12), thus making the conducting areas accessible through cuts (16) in the coupling studs (15). The invention also concerns a method of producing such a plate and a board consisting of a plurality of interconnected plates of said type.
