Abstract
An electrical connector for transformer studs accommodates two different size transformer studs in the same slip-fit blind hole. The hole is provided with circumferential arc recesses which are sized and threaded to match the threads on the two different size studs. One or more jam screws force the stud into the respective recesses, and the matching threads provide a substantial contact area and an effective and efficient long lasting and sturdy electrical transformer connection.
Claims15
An electrical connector for attachment to a transformer stud comprising an electrically conducting connector body having a blind stud receiving hole therein adapted to receive and accommodate at least two different size studs, said hole having circumference arcs formed by arcs having at least three centers, each of a different radius.
A method of making a slip-fit transformer stud electrical connector comprising the steps of forming a blind hole in an end of a connector body to form a cylindrical wall, forming a secondary hole offset from the center of said blind hole and thus removing part of said wall to form a first cylindrical recess in said cylindrical wall, forming a tertiary hole offset from the center of said secondary hole to form a symmetrical second cylindrical recess in said first cylindrical recess, said first and second cylindrical recesses being formed to match two different size transformer studs.
