Abstract

An electrostatic spray gun for the application of paints and other coatings has a high voltage power supply having a contact at the front end thereof. A flange on the end of the power supply surrounds the contact and a rubber boot seal snaps over the flange. Located within the rubber boot is a conductive rubber pin which contacts with a conductor located in the barrel of the gun. Utilization of this design minimizes capacitance in the front end of the gun and also virtually eliminates air volume in the area which in turn limits the production of harmful ozone.
