ELECTRONIC CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/059263
Kind Code:
A1
Abstract:
In order to prevent short-circuit failure between a conductive connection parts (1) for external electrical noise countermeasures and an electronic circuit, a large number of electronic components (8) are mounted on a circuit board (5) attached to a base (7), a metal cover (6) is provided so as to cover the upper parts of the electronic components (8), opening parts (3) are provided in four locations in the periphery of the circuit board (5), protruding members (12) formed integrally with the base (7) are provided at four locations in accordance with the positions of the opening parts (3), the protruding members (12) are caused to protrude from the back-surface side of the circuit board (5) through the four opening parts (3) to the front-surface side of the circuit board 5, the conductive connection parts (1) are disposed on the board-outward sides of the four protruding members (12), the protruding members (12) are disposed between the conductive connection parts (1) and the electronic circuit, and a grounded circuit is electrically connected to the metal cover (6) and the conductive connection parts (1).
