Abstract: An insulating member is used on or with a high-voltage probe that applies a voltage to the anode of a cathode ray tube during manufacture of the tube. If there are flaws in the frit seal of the tube, the probe produces arcing through the flaw into a grounded, conductive band disposed around the exterior of the frit seal. The insulating member is placed between the high-voltage probe tip and the grounded band around the frit seal. Consequently, the insulating member prevents electrical arcing external to the cathode ray tube between the high-voltage probe and the grounded band. Such arcing would otherwise interfere with the testing of the frit seal and could possibly damage the test equipment.

The lower surface can include or be placed upon a layer of electrically conductive compliant material, such as a conductive adhesive. At least one of the sidewalls can include a projecting fluted structure having a size and location that is predetermined to engage a side of the structure that exerts the compressive force.
