Description
技术领域technical field

背景技术Background technique
随着科学技术的不断发展，气体放电管的使用要求也越来越趋向于小型化与集成化。为了满足用户背板贴片的需求，需要尽量降低普通气体放电管的整体高度。目前常见的做法是，使用高度极小的绝缘管体配合两端的电极进行封装，并且将其中一个电极的引出脚弯曲延伸到与另一个电极的引出脚位于同一平面，以利于安装。但是，这种做法带来一个新的问题，即两个电极之间的爬距变小，容易导致击穿起火，危害电路的安全。With the continuous development of science and technology, the requirements for the use of gas discharge tubes tend to be more and more miniaturized and integrated.
