ABSTRACT:
A high voltage focus potentiometer module includes a housing having a plurality of connection cavities and corresponding wire guides formed therein. A substrate is secured within the housing. The substrate includes the stationary elements of the potentiometer, the wiper of which is located in a recess that is surrounded by a flexible seal. Conductive rubber inserts are loosely fitted in the cavities and are adapted to be piercingly engaged by wires in the wire guides and in contact with corresponding conductive pads on the substrate. Channels are provided in the housing to permit flowable epoxy to surround the conductive rubber inserts and wires in the cavities. A high voltage transformer includes a shell having an open side to which the potentiometer module is snap-fitted. A conductive element on the transformer is positioned in the open side and is adapted to be piercingly engaged by a conductive rubber plug that also engages a conductive pad on the other side of the substrate. The entire assembly is potted.
