Abstract
An electronic control device capable of suppressing failure of an electronic component due to static electricity is provided. An electronic control device that controls an actuator includes a circuit board, an electronic component mounted on the circuit board, a resin case (insulating case) that holds the circuit board, a metal cover (first conductive cover) that covers the resin case, an actuator cover (second conductive cover) that holds the resin case and covers an opening portion of the actuator, and a conductive portion that make the metal cover (first conductive cover) and the actuator cover (second conductive cover) conductive.
Claims26
An electronic control device that controls an actuator, the electronic control device comprising:
- a circuit board;
- an electronic component mounted on the circuit board;
- an insulating case that holds the circuit board;
- a first fixing member that fixes the circuit board to the insulating case;
- a first conductive cover that covers the insulating case;
- a second conductive cover that holds the insulating case and covers an opening portion of the actuator;
- a conductive portion that makes the first conductive cover and the second conductive cover conductive;
- a second fixing member that fixes the first conductive cover to the insulating case in a non-contact state with the second conductive cover;
- and
- a third fixing member that fixes the insulating case to the second conductive cover in a non-contact state with the first conductive cover.
