Abstract:
An interposer component adapted to receive a plurality of like metal contacts to form an interposer assembly for establishing electrical connections between pairs of opposed contact pads arranged in a pattern, said interposer component comprising;a plate formed from a single piece of insulating material;said plate having a flat top surface, a flat bottom surface extending parallel to the top surface and a uniform thickness;a plurality of single contact passages extending through the thickness of the plate from the top surface to the bottom surface thereof, said passages spaced apart from each other and arranged in a pattern corresponding to the pattern of the pairs of spaced contact pad pairs;each passage being elongate in transverse cross section and including opposed first and second passage ends, said first passage end being wider than said second passage end and comprising a first end wall, a pair of opposed parallel walls joining the first end wall and extending toward the second end, and a pair of opposed converging walls joining the parallel walls and extending to the second end, said parallel walls defining a uniform width portion of the passage adjacent the first end and said converging walls defining a reduced width portion of the passage adjacent the second end, said walls extending perpendicularly to the top and bottom surfaces of the plate; anda plurality of projections integrally formed from the insulating material, each projection located in a passage within the thickness of the plate and extending from the second end a distance into the passage to a projection end, said projection end spaced from said first end wall to define a narrowed passage portion therebetween so that the projection obstructs said passage mediate said top and bottom surfaces, each projection including a first contact camming surface facing the top surface of the plate and sloping from the projection end toward the top surface of the plate and a first contact retention surface facing the bottom surface of the plate, said projection end located between the camming surface and the retention surface.
