Description of the Related Art In a small boat, for example, a support cylinder is supported on a hull, an electric drive unit for an outboard motor is provided under the support cylinder, and a control unit for controlling the electric drive unit is provided in an upper case of the support cylinder. There is one that has.

要となり、また制御ユニットの内部には、電動駆動ユニ
ットを制御する電装部品を実装した基板が配置されてい
る。In a small boat, the wire connecting the electric drive unit and the control unit is, for example, several tens of amperes.
In order to flow (ampere), a thick conductor having a large cross-sectional area is required, and inside the control unit, a board on which electric components for controlling the electric drive unit are mounted is arranged.

【発明が解決しようとする課題】ところで、小型船舶の
場合には、制御ユニットの内部に水が侵入する虞があ
り、例え水が侵入することがあっても基板に水が着かな
いように配慮する必要がある。By the way, in the case of a small vessel, there is a risk that water may enter the inside of the control unit, and care should be taken to prevent water from reaching the substrate even if water may enter. There is a need to.
【０００５】また、電動駆動ユニットの出力向上を行な
うと、電動駆動ユニットを制御する電装部品は、発熱性
大の電装部品が増加し、全て電動駆動ユニットの内部に
収納することができなくなり、電動駆動ユニットの出力
向上に一定の限界がある。Further, when the output of the electric drive unit is improved, the number of electric components for controlling the electric drive unit increases, which makes it impossible to store all the electric components inside the electric drive unit. There is a certain limit to improving the output of the drive unit.
【０００６】このため、制御ユニットの内部の基板にも
発熱性大の電装部品が実装されるが、発熱性大の電装部
品を効率よく冷却することが要求される。例えば、発熱

付けるため、基板の取付け、配線、組付けが難しくな
る。For this reason, electric components having a large heat generating property are mounted on the board inside the control unit, but it is required to efficiently cool the electric component having a large heat generating property. For example, it is conceivable to directly attach an electrical component having a large heat generation to an aluminum case to cool it, but since the electronic component itself is assembled to the case, it becomes difficult to attach, wire and assemble the board.
【０００７】また、発熱性大の電装部品の発熱を放熱す
るためにヒートシンクが配置されるが、ヒートシンク
は、一つの部品として基板の上に立体的にレイアウトさ
れて置かれているために場所を取っていた。Further, a heat sink is arranged to dissipate the heat generated by the electric component having a great heat generating property. However, since the heat sink is one-dimensionally laid out on the substrate in a three-dimensional layout, the space for the heat sink is small. I was taking it.
【０００８】さらに、一枚の大きな基板上に、制御部と

ー部に配置されるため、太いパターンを制御部まで引き
出し、制御部の基板スペースを浪費していた。Further, the control section and the power section are separately arranged on one large substrate. For example, a current sensor or the like is arranged in the control section, but the circuit to be detected for current is in the power section. Since it is arranged, the thick pattern is drawn to the control unit, and the substrate space of the control unit is wasted.

しない等の問題がある。Further, for example, in order to detect the current of a large current circuit with a current sensor, the circuit is passed through the current sensor. However, since the current is large, the connecting terminal is large and the terminal is crimped after passing through the wire. Therefore, the terminal crimping process in the assembly process is inefficient, and since the terminal crimping process is performed after the wire is passed through the current sensor, the terminal crimping process is a manual operation and the quality is not stable.

On the other hand, in a control device for an electric outboard motor, in which a control unit for controlling the electric drive unit is provided on an upper side of a support cylinder, a board is separated from a bottom surface of the lower case inside a lower case and an upper case of the control unit. The upper case and the lower case are located above the mating surface of the lower case and the upper case. The board is separated from the bottom surface of the lower case and is located higher than the mating surface of the lower case and the upper case, so that even if water enters the case, water does not directly reach the electrical components of the board. As a result, it is possible to prevent short-circuiting and corrosion of electrical components. Further, since the substrate is separated from the bottom surface of the lower case, it is easy to attach and detach the substrate.
