表面安装放电管，在电极侧面周边具有焊接斜面，从圆柱形陶瓷外壳的相对端密封并向外突出
Surface mounting discharge tube has soldering tapers formed at peripheral edges of electrode side surfaces that seal and project outwardly from opposite ends of cylindrical ceramic envelope
US-7719174-B2用于表面安装的放电管。
专利摘要
一种表面安装放电管，包括由电极侧面密封两端的圆柱形陶瓷外壳，设计为直接焊接在安装板上，其中两端的电极为矩形，在陶瓷外壳的端部径向向外突出，并在电极侧面的周边边缘处设有焊接用斜面或台阶差，从而抑制焊接时的位置偏差并确保足够的PCT性能。
Original abstractA surface mounting discharge tube, comprise of a cylindrical ceramic envelope sealed at its two ends by side surfaces of electrodes, designed to be directly soldered on to a mounting board, where the electrodes at the two ends are rectangular, project outward radially at the ends of the ceramic envelope and are provided at peripheral edges at the side surfaces of the electrodes with soldering use tapers or step differences, whereby positional deviation at the time of soldering is suppressed and sufficient PCT properties are secured.
