Abstract
To provide an electronic control device capable of securing electromagnetic compatibility and mechanical strength. An electronic control device includes a base portion formed in a bottomed cylindrical shape; an electronic control board provided in the base portion; and connectors provided on an opening side of the base portion and electrically connected to the electronic control board, in which the base portion includes a first layer formed of a conductive member and a second layer formed of a member different from that of the first layer.
Claims16
An electronic control device comprising:
- a base portion formed in a square tubular shape;
- an electronic control board provided in the base portion;
- a connector provided on an opening side of the base portion and electrically connected to the electronic control board;
- and
- an attachment portion comprising an insulating member made of an insulating material and formed to protrude outward from an outer side surface of the base portion and attached to an other device, wherein the attachment portion comprises a plurality of conductive protrusions formed of a conductive material that extends into the insulating material, the insulating member having two side walls and a through hole for attaching to the other device, wherein the plurality of conductive protrusions are provided within a width of the insulating member,
- wherein the base portion includes at least one first layer formed of a conductive member, and
- at least one second layer formed of a member different from that of the first layer.
An electronic control device comprising:
- a base portion formed in a square tubular shape;
- an electronic control board provided in the base portion;
