Abstract

An electronic device includes a first circuit board and a second circuit board arranged to have their first main surfaces facing each other, and a casing containing the first and second circuit boards. The first circuit board has the first main surface having a first electronic component with a mounting height from the first main surface toward the second circuit board greater than a distance between the first and second circuit boards. The second circuit board has an opening or a cutout as a first hollow portion facing the first electronic component. The first hollow portion receives a part of the first electronic component.

First claim

The invention claimed is:

1. An electronic device, comprising:
a first circuit board and a second circuit board each having a front surface and a back surface as a first main surface and a second main surface, the first circuit board and the second circuit board being arranged at a distance from each other with the first main surfaces of the first and second circuit boards facing each other; and
a casing containing the first circuit board and the second circuit board, wherein the first main surface of the first circuit board allows mounting of a first electronic component having a mounting height from the first main surface of the first circuit board toward the second circuit board greater than the distance between the first circuit board and the second circuit board,
the second circuit board comprises a first hollow portion arranged as an opening or a cutout at a position facing the first electronic component,
the first hollow portion receives a part of the first electronic component the casing comprises a box-shaped first casing that accommodates the first circuit board such that the second circuit board is provided outside of the box-shaped first casing, and
the box-shaped first casing has a first opening through which the first electronic component is placed;
the casing comprises a box-shape second casing containing and retaining the side in a direction in which the first circuit board and the second circuit board face each other and are fitted together:
wherein the first casing has the first opening at a position facing the second casing,
the second casing has a second opening at a position facing the first casing, and
the first electronic component is placed through the first opening and the second opening.

2. The electronic device according to claim 1 , wherein each of the first casing and the second casing includes a pair of covers that are arranged side by side in the facing direction and are fitted together.

3. The electronic device according to claim 1 , wherein
the first electronic component is a relay or a transformer.

4. The electronic device according to claim 1 , wherein
the second circuit board allows mounting of a second electronic component having a mounting height from the first main surface of the second circuit board toward the first circuit board greater than the distance between the first circuit board and the second circuit board,
the first circuit board comprises a second hollow portion arranged as an opening or a cutout at a position facing the second electronic component, and
the second hollow portion receives a part of the second electronic component.

5. The electronic device according to claim 4 ,
wherein
the first electronic component and the second electronic component are placed through the first opening and the second opening.

6. The electronic device according to claim 5 , wherein
each of the first casing and the second casing includes a pair of covers that are arranged side by side in the facing direction and are fitted together.

7. The electronic device according to claim 4 , wherein
each of the first electronic component and the second electronic component is a relay or a transformer.

8. An electronic device, comprising:
a first circuit board and a second circuit board each having a front surface and a back surface as a first main surface and a second main surface, the first circuit board and the second circuit board being arranged at a distance from each other with the first main surfaces of the first and second circuit boards facing each other; and
a casing containing the first circuit board and the second circuit board, wherein
the first main surface the first circuit board allows mounting of a first electronic component having a mounting height from the first main surface of the first circuit board toward the second circuit board greater than the distance between the first circuit board and the second circuit board,
the second circuit board comprises a first hollow portion arranged as an opening or a cutout at a position facing the first electronic component,
the first hollow portion receives a part of the first electronic component,
the casing comprises a first casing containing and retaining the first circuit board, and a second casing containing and retaining the second circuit board,
the first casing and the second casing are arranged side by side in a direction in which the first circuit board and the second circuit board face each other and are fitted together,
the first casing and the second casing are box-shaped,
the first casing has a first opening at a position facing the second casing,
the second casing has a second opening at a position facing the first casing, and
