Electronic control unit

摘要

An electronic control unit is configured in such a way that the groove-shaped concave portion of the second case member includes a first concave portion, in which a groove width at a bottom surface side is narrow, and a second concave portion, in which a groove width at an aperture surface side is wide, and the first concave portion and the second concave portion are linked by an inclined step portion in such a way that a groove width at the step portion is increased in a direction from the bottom surface side to the aperture surface side, and moreover, a tip of the rail-shaped convex portion of the first case member is fitted into the first concave portion at the bottom surface side of the second case member.

主权项

1. An electronic control unit comprising:
an electronic circuit board on which electronic components are mounted; and a case for housing the electronic circuit board; wherein the case is composed of two case members fitted together and has a configuration in which a rail-shaped convex portion of a first case member is fitted to a groove-shaped concave portion of a second case member, and both case members are bonded and assembled by an adhesive between the rail-shaped convex portion of the first case member and the groove-shaped concave portion of the second case member; and moreover, the case is configured in such a way that the groove-shaped concave portion of the second case member includes a first concave portion, in which a groove width at a bottom surface side is narrow, and a second concave portion, in which a groove width at an aperture surface side is wide; and the first concave portion and the second concave portion are linked by an inclined step portion in which a groove width at the step portion is increased in a direction from the bottom surface side to the aperture surface side; and a tip of the rail-shaped convex portion of the first case member is fitted into the first concave portion at the bottom surface side of the second case member.
