In order to avoid the serious danger of deep charge and discharge of the remote sensor, reduce the impact of space electrostatic discharge on the remote sensor, and meet the requirements of electromagnetic compatibility, the corresponding protection design must be carried out for the remote sensor. The source of deep charge and discharge is high-energy electrons (100keV ~ 10MeV), and the objects of deep charge and discharge effect are isolated conductors and dielectric materials. Dielectric materials such as circuit boards, cable sheaths, glue, etc., these dielectric materials have mature technology for electrostatic control. For isolated conductors, conductors with an area of more than 3cm2 or a length of more than 25cm, such as DC-DC, relays and other metal-encapsulated components, there are already standardized processes that require grounding and shielding. However, such as the miniature magnetic latching relay 2JB0.5-1 device, the surface metal package, no grounding pin, the surface area is 7.34cm 2 , it cannot be grounded in a conventional way, so a special grounding treatment method is required.
