Title:
ELECTRONIC CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2021086985
Kind Code:
A
Abstract:
To solve the problem that a connection part cannot be provided to the neighborhood of a tall electronic component, and a high-frequency electromagnetic noise cannot be sufficiently suppressed.SOLUTION: By setting a housing 201 to a duplex structure by using a duplex member 203, a cutting part 204 for avoiding interference between an electron component 104 on a circuit board 101 is provided to the duplex member 203. Further, a cutting part 205 for separating a part of a connector 105-A is formed on the duplex member 203. Thus, the interference between the tall electronic component 104 is avoided, and a noise source generated by integration circuits 102-A to C as a noise source and its circumference pattern are confined to suppress an unwanted electromagnetic radiation that is entered from or drained to the connector 105-A part. The unwanted electromagnetic radiation can be suppressed by confining more fully noises because an inner part of the housing 201 has the duplex structure by using the duplex member 203, and a strength of the housing can be improved.SELECTED DRAWING: Figure 2
