Support for circuit boards

Claim 1

A one-piece support of plastic dielectric insulation material for mounting an apertured circuit board spaced from an apertured chassis, said support comprising a rigid shaft, a resiliently yieldable base at one end of said shaft adapted to bear against the top surface of the apertured chassis, mounting means extending from the base adapted to be projected through the chassis aperture, flexible return portions on said mounting means having free ends adapted under tension of the resiliently yieldable base to partially re-enter the chassis aperture, straight abrupt shoulders adjacent the free ends of the return portions adapted to abut the chassis surface in the area surrounding its aperture so as to prevent withdrawal of the mounting means from the aperture, and a coupling member on the other end of the shaft adapted to enter the circuit board aperture for removably securing said circuit board on the support comprised of diverging and converging yieldable walls and a deflectable arm integral with and between said walls adapted to enter into the circuit board aperture to limit deflection thereof, an abrupt shoulder on said arm adapted to be abutted by the circuit board to prevent unintended separation of the board from the coupling member.
