Abstract
An electrical connector in which conductive rubber rods are mounted in a nonconductive substrate. The rods extend above and below the upper and lower surfaces, respectively, of the substrate for electrically interconnecting conductive traces on a pair of electronic components, such as a display panel and logic circuit used in a digital wrist watch. A method for making the connect is disclosed.
Claims2
A conductive elastomer connector comprising:
- a nonconductive planar substrate having generally parallel upper and lower surfaces;
- a plurality of etched holes extending through said substrate from said upper surface to said lower surface;
- a conductive elastomer rod retained in each of said holes, said rods extending above said upper surface and below said lower surface;
- each said etched hole having an underetch pattern providing an inwardly extending annular ridge spaced from said upper and lower sufaces;
- and
- each said rod having an annular recess in its outer surface spaced from said upper and lower surfaces and receiving said annular ridge therein whereby said rods are retained in said holes by said ridges.
