Title:
STATIC ELECTRICITY PROTECTION CIRCUIT, CIRCUIT BOARD AND STATIC ELECTRICITY PROTECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/177238
Kind Code:
A1
Abstract:
Disclosed are a static electricity protection circuit, a circuit board and a static electricity protection method. The static electricity protection circuit comprises a first relay (101) and a second relay (102), wherein control ends of the first relay and the second relay are respectively connected to a power supply (104) of a system circuit (103); the first relay and the second relay are connected in series between the system circuit and a grounding end (105) to form an electric charge release passage; and the first relay switches, when the system circuit is powered off, from an open-circuit state to a short-circuit state, and the electric charge release passage is in a conducting state after the first relay switches to the short-circuit state, so as to release electrostatic charges in the system circuit.
