<p>A cathode ray tube socket with capability for separately grounding the high voltage pin on the one hand, and the remainder of the pins on the other, in the event of a voltage excess in the pins. Separate grounding prevents a spark from jumping from the high voltage pin to ground and then back to one of the remaining pins, thus damaging the tube. The socket comprises an insulating support and a plurality of metal contacts mounted therein and adapted to conductively receive the tube pins. Included within the support are electrically and physically separate first and second grounding plates. The first grounding plate is spaced from the contact associated with the high voltage pin and the second grounding plate is spaced from the contacts associated with the remaining pins. Means are also provided for independently electrically connecting each of the grounding plates to ground such that sparks can bridge the gap between the respective grounding plates and the contacts associated therewith without affecting the other contacts so as to damage the tube.</p> |
