Abstract
A self-aligning guide pin has two tapered protrusions. The protrusions seat in recesses in a printed circuit board to properly position and align the guide pin as it is mounted by a screw to the printed circuit board during assembly.
Claims29
A method of attaching a guide pin to a printed circuit board comprising the steps of:
- a) providing a printed circuit board having two circular recesses and a screw hole defined therein;
- b) providing a guide pin having an elongate shaft defining a screw hole extending through the shaft member in a direction transverse to the shaft, said guide pin further including two tapered protrusions, square in transverse cross section, and sized in relation to the mating circular recess as follows:
- i) smaller in distance from corner to corner at its terminating end than the diameter of the circular recesses;
- and
- ii) greater in distance from corner to corner at its widest end than the diameter of the circular recesses;
- c) providing a mounting screw;
- d) positioning the guide pin adjacent the printed circuit board with said protrusions extending into said recesses;
- e) installing the mounting screw through the screw hole on the printed circuit board;
- f) tightening said mounting screw within said guide pin screw hole until corners of said protrusions bite into the printed circuit board.
