Japanese Patent No. 5391728

  An object of the present invention is to provide a technique for simplifying an electrical unit having a waterproof structure in a saddle-ride type vehicle in which an arrangement space is limited.

  The invention according to claim 1 is provided integrally with a resin-made main body case, a circuit board supported in the main body case, a lid member for closing the main body case storing the circuit board, and the lid member. An electrical unit for a saddle-ride type vehicle in which a vehicle body harness comprising an electrical component having one coupler and the other coupler connected to one coupler and a cover made of an elastic member covering the periphery of the other coupler is connected The cover is provided with a harness outlet that is located on the side farther from the other coupler and through which the vehicle body harness passes, and the end of the electrical component located on the side closer to the electrical component of the cover covers the opening of the main body case. A vehicle body harness is connected to the electrical component so as to be in close contact with the side wall.

  The invention according to claim 2 is such that the minimum inner diameter portion of the harness outlet is provided at the lowermost end of the cover, is formed smaller than the outer diameter of the other coupler and larger than the outer diameter of the body harness, The electrical component is supported such that the opening of the case opens downward and the connection port of one coupler to which the other coupler is connected faces downward.

  In the invention according to claim 3, one bead is provided on the side wall of the main body case provided in the electrical component substantially parallel to the edge of the opening, and the bead is fitted to the electrical component side end of the cover. The other bead is provided.

  In the invention according to claim 4, the cover is further provided with an upper extending portion extending upward, and the upper extending portion is provided with a supported hole penetrating vertically, and the supported hole is disposed on the vehicle body side. It is inserted into the provided vehicle body side claw portion, and the electrical component is supported on the vehicle body side.

  In the invention according to claim 5, the main body case is further provided with a retaining claw that extends downward from the upper part of the side surface of the main body case and has a step at the tip, and the cover is closer to the main body case than the supported hole. Further, a retaining hole to which the retaining claw is engaged is provided.

  The invention according to claim 6 is characterized in that the retaining hole provided in the cover is provided above the other bead in the axial direction of the electrical component.

In the invention according to claim 1, the opening of the main body case which is a component of the electrical component is opened downward, and this opening is covered with a cover provided in the vehicle body harness.
Conventionally, the waterproof structure of the electrical component has a waterproof structure between the main body case and the lid member that closes the main body case.

  In this regard, in the present invention, since the opening of the electrical component is covered with the cover provided in the vehicle body harness, it is not necessary to provide a waterproof structure between the main body case and the lid member. As a result, the waterproof structure of the electrical component can be simplified as compared with the case where a waterproof structure is provided between the main body case and the lid member.

  In the invention according to claim 2, the minimum inner diameter portion of the cover is provided at the lowermost end of the cover, and is formed larger than the outer diameter of the body harness with a gap. Even when moisture enters the cover, the water flows downward from the minimum inner diameter portion provided at the lowermost end, so there is no concern that water will accumulate in the cover.

  In the invention which concerns on Claim 3, one bead was provided in the side wall of the main body case, the other bead was provided in the electrical equipment side edge part of the cover, and the other bead was made to fit in one bead. By fitting the other bead into one bead, the waterproofness between the body case of the electrical component and the cover of the vehicle body harness can be enhanced.

Since the cover also serves as a support for the vehicle body, the number of parts can be reduced. In addition, since the electrical component is supported on the vehicle body side via a cover made of an elastic member, transmission of vibrations of the vehicle body to the electrical component can be blocked.

  In the invention which concerns on Claim 5, the load of an electrical component is supported by the vehicle body via an upper extension part. The cover is provided with a retaining hole with which the retaining claw is engaged at a position closer to the main body case than the supported hole for supporting the electrical component. Since there is a retaining claw, not only does the electrical component not come out upward, but also when the downward force is applied to the cover, it can be made difficult to remove the cover.

  In the invention according to claim 6, the retaining hole is provided above the other bead in the axial direction of the electrical component. When the load of the electrical component is applied to the cover, the load is applied to the retaining hole and is not easily applied to the other bead, so that the other bead is not easily deformed and the influence on the waterproof performance is small. As a result, there is no worry that the waterproof performance is impaired.
