ABSTRACT:
This invention secures the breakdown voltage between stem pins or the like for high voltage service in a cathode ray tube. This insulator is formed of a clay-like silicone compound having a tip-throughhole and pin-throughholes or a stem base with the electric insulator mounted to the stem base. An inter-stem electric insulation device is structured by mounting either one of the electric insulator or the stem base with the electric insulator to the stem of a cathode ray tube and by pressing to fix together. This structure does not allow bubble generation caused by the electric insulator, and makes the handling easy, and furthermore, allows an automatic mounting of the electric insulator to a stem.
