Abstract

An electronic control apparatus includes a connector cover that: closes a first aperture; and has a second aperture through which a first side of a connector extends. The connector cover includes a covering wall that covers at least a second side of the connector that faces a second direction. Thus, since the connector is covered by the covering wall, it is possible to prevent a foreign object, dust, etc. from entering the case.

Claims

1. An electronic control apparatus that electronically controls a controlled object, the electronic control apparatus comprising:

a case that includes a first aperture on a surface that faces in a first direction;

a first electronic circuit board that slides into the case through the first aperture so as to be inserted into the case;

a connector that is mounted on an end portion of the first electronic circuit board, the end portion being an end of the first electronic circuit board facing in the first direction, the connector having first and second oppositely facing sides, the first side of the connector having a terminal facing the first direction, the second side of the connector facing in a second direction opposite the first direction; and

a lid that closes the first aperture, the lid having a second aperture through which the first side of the connector extends, wherein

the lid includes a covering wall that covers at least the second side of the connector that faces the second direction.

2. The electronic control apparatus according to claim 1, wherein

the covering wall includes a first wall surface that covers the second side of the connector, and second, third and fourth wall surfaces that respectively cover three additional sides of the connector that extend in three directions other than a direction in which the connector is in contact with the first electronic circuit board, out of four directions orthogonal to the second direction.

3. The electronic control apparatus according to claim 1, further comprising:

a projection that projects from the covering wall in the second direction;

a slit in the covering wall, the slit extending along a direction orthogonal to the second direction, the slit providing an elastic force to the projection in the second direction when the projection is pressed in the first direction; and

a second electronic circuit board that abuts on the projection and is secured within the case by the elastic force.

4. The electronic control apparatus according to claim 1, further comprising:

guiding grooves provided in inner side surfaces of the case and along which the first electronic circuit board slides into the case through the first aperture.

5. The electronic control apparatus according to claim 4, wherein

a width of each of the guiding grooves decreases as each groove progresses further rearward into the case.

6. A method for producing an electronic control apparatus that includes a case having a first aperture on a surface that faces in a first direction, the method comprising:

(a) sliding a first electronic circuit board into the case through the first aperture;

(b) mounting a connector on an end portion of the first electronic circuit board, the end portion being an end of the first electronic circuit board facing in the first direction, the connector having first and second oppositely facing sides, the first side of the connector having a terminal facing the first direction;

the second side of the connector facing in a second direction opposite the first direction; and

(c) closing the first aperture of the case with a lid having a second aperture through which the first side of the connector extends, wherein

the lid includes a covering wall that covers at least the second side of the connector that faces the second direction.

7. The method according to claim 6, wherein

the covering wall includes a first wall surface that covers the second side of the connector, and second, third and fourth wall surfaces that respectively cover three additional sides of the connector that extend in three directions other than a direction in which the connector is in contact with the first electronic circuit board, out of four directions orthogonal to the second direction.

8. The method according to claim 6, wherein

a projection projects from the covering wall in the second direction;

a slit is provided in the covering wall, the slit extending along a direction orthogonal to the second direction, the slit providing an elastic force to the projection in the second direction when the projection is pressed in the first direction; and

a second electronic circuit board abuts on the projection and is secured by the elastic force.

9. The method according to claim 6, wherein

guiding grooves are provided in inner side surfaces of the case and along which the first electronic circuit board slides into the case through the first aperture.

10. The method according to claim 9, wherein

a width of each of the guiding grooves decreases as each groove progresses further rearward into the case.
