    • A method of insulating a cathode ray tube and an electrical insulator composition for a cathode ray tube enabling an electrical insulator to be produced without material loss and enabling improvement of the bonding strength between a stem (20) and a stem base (30) and the insulation property between stem pins (21), when attaching to a stem (20), which is provided at the cathode ray tube (1a) and has a tip (22) and stem pins (21) projecting therefrom, an insulating stem base, which comprises a base (31) through which pin through holes are formed and has provided projecting from the front surface thereof a tip holder (32), in a state with the stem pins (21) inserted through the pin through holes and the tip (22) held in the tip holder (32), said method comprising the steps of molding an electrical insulator composition comprising an uncured self-adhesive silicone rubber into a predetermined sheet shape by using a transfer mold to obtain an electrical insulator (10), arranging the electrical insulator in a state extending from the positions of the pin through holes on the back of the base (31) of the stem base (30) to the tip holder (32) and adhering it to the back of the base, folding the portion of the electrical insulator extending to the tip holder (32) to the inside surface of the tip holder, and attaching the stem base (30) to the stem (20).
    • 无杆(20)和柄底座(30)之间的材料损耗和的接合强度能够提高待生产绝缘的阴极射线管在用于阴极射线管使得能够电绝缘体电绝缘组合物的和的方法和 芯柱插脚之间的绝缘性(21)。当附接至从那里绝缘干基座伸出有一个杆(20),所有这些是在阴极射线管(1A),并具有前端(22)和杆销(21), 它包括一个基座(31)通过的通孔,其销形成,并具有提供在一个状态下,从正面投射它们的刀片保持器(32),通过所述销插入杆销(21)的通孔和顶端( 22)在所述焊嘴夹(32),所述方法通过使用转印模具,以获得在电绝缘体(10)包括模制的电绝缘组合物未固化的自粘合性硅橡胶的,其包括成预定板材形状的步骤,安排举行 该ELECTRI CAL绝缘体在从销的位置的通孔中茎基部(30),以在刀片保持器(32)的基部(31)的后部延伸,它秉承基体的背面,折叠的部分的状态下 的电绝缘体延伸到所述刀片保持器(32)与刀片保持器的内表面,以及将所述杆基座(30)在阀杆(20)。
