Control device and motor device
Provided is a control device and a motor device that can effectively suppress influence of vibration of a specific electronic component. A coil that is the specific electronic component is mounted on a circuit board. A connector portion has a base portion extending in a thickness direction of the circuit board and an extended portion extending from the base portion in a direction in which the circuit board extends. The extended portion of the connector portion has an annular portion, a support portion, and a pedestal portion. The pedestal portion serves as a portion to which the coil is bonded and fixed. With an adhesive applied to the pedestal portion, the pedestal portion bonds and fixes the coil thereto.
1. A control device comprising:
a plurality of electronic components;
a circuit board on which the electronic components are mounted; and
a connector portion provided on the circuit board and configured to exchange information with an external device, wherein:
the electronic components include a specific electronic component disposed adjacent to the connector portion, the specific electronic component having at least one side surface that protrudes vertically with respect to a thickness direction of the circuit board;
the connector portion has a base portion extending in the thickness direction of the circuit board and an extended portion extending from the base portion in a direction in which the circuit board extends; and
the extended portion has a pedestal portion (i) positioned at the at least one side surface of the specific electronic component and (ii) bonded and fixed to the specific electronic component.
2. The control device according to claim 1 , wherein the pedestal portion and the specific electronic component are bonded and fixed to each other with adhesive in the direction in which the circuit board extends, and at the at least one side surface.
3. The control device according to claim 1 , wherein the pedestal portion is disposed further away from the circuit board in the thickness direction of the circuit board than a center of gravity of the specific electronic component.
4. The control device according to claim 1 , wherein the pedestal portion is disposed further away from the circuit board in the thickness direction of the circuit board than an intermediate point of the specific electronic component in the thickness direction of the circuit board.
5. The control device according to claim 1 , wherein the pedestal portion has an inclined face such that a thickness of the pedestal portion decreases toward a distal end of the pedestal portion.
6. A motor device comprising:
the control device according to claim 1 ;
a motor;
a motor housing that accommodates the motor; and
a cover that covers the circuit board and the connector portion, wherein:
the thickness direction of the circuit board coincides with an axial direction of the motor;
a magnetic sensor for detecting a rotation angle of a rotary shaft of the motor is mounted on the circuit board on an extended line of the rotary shaft; and
the specific electronic component is a coil that is mounted on a peripheral edge of the circuit board.
7. The control device according to claim 1 , wherein the pedestal portion is arcuate-shaped.
8. A control device comprising:
a plurality of electronic components;
a circuit board on which the electronic components are mounted; and
a connector portion provided on the circuit board and configured to exchange information with an external device, wherein:
the electronic components include a specific electronic component disposed adjacent to the connector portion, the specific electronic component having at least one side surface that protrudes vertically with respect to a thickness direction of the circuit board;
the connector portion has a base portion extending in the thickness direction of the circuit board and an extended portion extending from the base portion in a direction in which the circuit board extends;
the extended portion has a pedestal portion (i) positioned at the at least one side surface of the specific electronic component and (ii) bonded and fixed to the specific electronic component; and
wherein the pedestal portion suppresses vibration of the specific electronic component.
