Abstract
A control circuit is molded with a package portion and connected with first terminals. A wiring portion includes second terminals connected with the first terminals and partially molded with a molded portion. The molded portion includes a first fitting portion surrounding the control circuit. A cover portion includes a second fitting portion fitted to the first fitting portion to cover the control circuit. The first and second fitting portions form a gap therebetween. The gap extends in a crank form along a first direction and extends in a crank form along a second direction, which is perpendicular to the first direction.
Claims6
An electronic control unit comprising:
- a control circuit portion including a control circuit, a package portion molded with the control circuit, and a plurality of first terminals electrically connected with the control circuit and exposed to an outside of the package portion;
- a wiring unit including a plurality of second terminals electrically connected with the plurality of first terminals, and a molded portion molded with a part of the plurality of second terminals, the molded portion including a first fitting portion located on a side of the control circuit portion, the first fitting portion being in a frame shape and surrounding the control circuit portion;
- a cover portion including a second fitting portion fitted to the first fitting portion of the wiring unit to cover the control circuit portion, wherein the first fitting portion and the second fitting portion form a gap therebetween, the gap extending in a crank form along a first direction and extending in a crank form along a second direction, which is perpendicular to the first direction, wherein the first fitting portion includes a recessed-and-projected portion extending in a staggered form along the first direction, the second fitting portion includes a projected-and-recessed portion extending in a staggered form along the first direction, the projected-and-recessed portion corresponding to the recessed-and-projected portion, and each of the recessed-and-projected portion and the projected-and-recessed portion include a recessed portion having a width in the first direction, the width is smaller than both a first distance between two of the plurality of first terminals, which are adjacent to each other, and a second distance between two of the plurality of second terminals, which are adjacent to each other.
