Abstract: A mirror for a rear projection television receiver is formed of stretched and heat-shrunk metallized plastic film A U-shaped aluminum frame is formed out of roll stock and cut and bent into the desired shape The frame has a flat front surface that includes a smooth raised inner edge in contact with the metallized plastic film, which is adhesively secured to the flat front surface of the frame. A rigid backing is secured in close proximity to the metallized plastic film by having its edges sandwiched by the U-shaped frame. The frame has support brackets affixed thereto.

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.

Abstract: A quick release apparatus for a high voltage line connecting to a CRT sweep transformer has a plug with a split sleeve for grasping and retaining the high voltage lead when inserted into the transformer housing. The transformer housing contains an insulative sleeve as well as a conductive rubber pad for shorting the lead to the sweep transformer. The quick disconnect system is reliable and easily manufactured owing to its few parts.

Abstract: A junction box provides for interconnecting a plurality of sheathed, bare-end, high-voltage conductors for cathode ray tubes and the like. The junction box includes an enclosure, a plurality of spaced, parallel-arranged leaf-spring terminals mounted within the enclosure, and a like plurality of guides for guiding conductors into the enclosure and into contact with respective terminals. Ganged cams mounted on a slider provide for simultaneously locking a plurality of conductors in the enclosure against withdrawal by counter-deflecting the terminals against the conductors and prevent withdrawal from the enclosure. In addition to the quick connection of high-voltage conductors, the junction box provides for controlling the static and dynamic focusing of an electron gun.

Abstract: A high voltage disconnect plug and a receptacle therefor are described for use in coupling a high voltage conductor to a load such as a CRT. The plug includes a lock nut and a deformable annular ring through which the conductor passes, and a hollow sleeve which slides over the conductor to capture the ring between the sleeve and the lock nut. A spring carried by the sleeve engages a contact on an end of the conductor which passes through the sleeve. Insertion of the plug into a bore in the receptacle compresses the spring between the conductor's contact and a high voltage contact in the bore for coupling high voltage to the latter contact. Locking the nut to the receptacle deforms the ring to tightly seal it against the receptacle's inner wall around the bore.
