Title:
ELECTRONIC CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/024184
Kind Code:
A1
Abstract:
The present disclosure provides an electronic control device that can improve electromagnetic compatibility, while preventing a conductive connection part from unnecessarily extending on the surface of a circuit board. This electronic control device comprises a circuit board 110, a base part 120 made from resin, a metallic cover, a conductive connection part 140, and a flow preventing part 150. The circuit board 110 comprises: a target wire 111 as the object of noise reduction; an electronic component 112 that is mounted in the vicinity of the target wire 111; a signal ground 114 that is connected to the electronic component 112; and a housing ground 113 that is connected to the signal ground 114 via the electronic component 112 and that is connected to the cover via the conductive connection part 140. The flow preventing part 150 comprises a communication path 151 between the conductive connection part 140 and the electronic component 112. The housing ground 113 comprises: a first connection part 113a that is connected to the conductive connection part 140; a second connection part 113b that is connected to the electronic component 112; and a communication part 113c that passes through the communication path 151 and connects the first connection part 113a and the second connection part 113b.
