Title:
ELECTRONIC CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/131599
Kind Code:
A1
Abstract:
The present invention suppresses external leakage of high frequency radiation noise emitted from a noise source. An electronic control device 1 is provided with: a printed circuit board 101 which has signal grounds 104a, 104b, 104c and a frame ground 103a; a housing 100 which houses the printed circuit board 101; and a connector 105 which is mounted to the printed circuit board 101. The electronic control device 1 has a first coupling unit 301 which AC couples the signal ground 104a and the frame ground 103a, and a second coupling unit 301 which electrically couples the frame ground 103a and the housing 100. The first coupling unit 301 and the second coupling unit 301 are provided between the connector 105 and an electronic circuit 110 on the printed circuit board 101.
