Abstract
A device which provides electrical grounding between a conductive screen and a cathode ray tube (CRT) mounted in a monitor includes a conductive piece which is electrically connected to the conductive screen. When the conductive screen is mounted over the CRT the conductive piece exerts a spring force on a conductive strap on the CRT, thus establishing electrical connection between the conductive piece and the CRT. A coating of electrically conducting paint may also be used to facilitate conduction between the conducting piece and the conductive strap.
Claims8
In a monitor on which is mounted a conductive screen, a device for grounding the conductive screen to a cathode ray tube in the monitor, the device comprising:
- a conductive piece, electrically coupled to the conductive screen, which when the cathode ray tube is mounted in the monitor exerts a spring force on the cathode ray tube establishing electrical connection between the conductive piece and the cathode ray tube.
A method for grounding a conductive screen mounted on a monitor to a cathode ray tube the method comprising the steps of:
- (a) electro-mechanically connecting a conductive piece to the conductive screen, the conductive piece shaped so that upon mounting the conductive screen on the monitor the conductive piece will exert a spring force on the cathode ray tube establishing electrical connection between the conductive piece and the cathode ray tube;
- and
- (b) mounting the conductive screen on the monitor.
