Abstract

The electron beam acceleration voltage applied to the anode of a CRT is of a sufficiently high magnitude as to be hazardous. Sometimes it is necessary to measure that high voltage at the CRT anode in diagnosing faults in the tube. In order to promote the safety and convenience to the operator in making contact with the CRT anode in order to measure the high voltage, the CRT anode connection extender disclosed herein was devised.

CRT Anode Connection Extender

The electron beam acceleration voltage applied to the anode of a CRT is of a sufficiently high magnitude as to be hazardous. Sometimes it is necessary to measure that high voltage at the CRT anode in diagnosing faults in the tube. In order to promote the safety and convenience to the operator in making contact with the CRT anode in order to measure the high voltage, the CRT anode connection extender disclosed herein was devised.

Fig. 1 illustrates the extender. The three wires 1 are mounted into the annular connector 2 and are spring biased in an outward direction. As is shown in Fig. 2, the wires 1 can be inserted into the CRT anode exposed in the side of the CRT and then the plug which would normally snap into place in the anode is, instead, snapped into place on the annular base of the connector. Then, a high voltage measuring probe can be connected to one of the wires 1 so as to enable the safe and convenient measurement of the high voltage on the anode.
