Power conversion apparatus
View Patent ↗Provided is a power conversion apparatus that can enhance the strength of the vicinity of an opening through which a connector is exposed, and can prevent water from entering a casing through the opening or reduce such water intrusion. The power conversion apparatus includes a circuit board, a connector mounted on the circuit board, and a lid having an opening to allow the connector to be exposed therethrough and placed over the circuit board and the connector. The lid includes a bead that protrudes from a top plate to enclose an exposed portion of the connector.
1. A power conversion apparatus comprising:
a circuit board;
a connector mounted on the circuit board; and
a lid that is placed over the circuit board and the connector, said lid having a top plate that defines an opening through which the connector extends so as to define an exposed portion of the connector, and
wherein the lid integrally includes a bead that protrudes upwardly from the top plate and extends at least partially around the opening so as to at least partially surround the opening and the exposed portion of the connector that extends from said opening.
2. A structure for mounting the power conversion apparatus of claim 1 onto a vehicle, wherein the top plate of the lid is provided at an angle relative to a horizontal plane, and
the bead continuously encloses the connector and is at a position ranging from higher than any portion of the connector to at least a height level with a highest portion of the connector, using the top plate as a reference.
3. The power conversion apparatus according to claim 1 , wherein the bead includes an upwardly protruding portion that is relatively higher than any portion of the connector.
4. The power conversion apparatus according to claim 3 , further comprising a cover member that extends over and covers the opening, and wherein the cover member is attached to the protruding portion.
5. A power conversion apparatus comprising:
a circuit board;
a connector mounted on the circuit board; and
a lid that is placed over the circuit board and the connector, said lid having a top plate that defines an opening through which the connector extends so as to define an exposed portion of the connector,
wherein the lid integrally includes a bead that protrudes upwardly from the top plate and extends at least partially around the opening so as to at least partially surround the exposed portion of the connector that extends from said opening; and,
a cover member that extends over and covers the opening, and wherein the cover member is attached to the bead.
6. The power conversion apparatus of claim 5 , wherein the top plate of the lid is provided at an angle relative to a horizontal plane, and
the bead continuously encloses the connector and is at a position ranging from higher than any portion of the connector to at least a height level with a highest portion of the connector, using the top plate as a reference.
7. A power conversion apparatus comprising:
a circuit board;
a connector mounted on the circuit board; and
a lid that is placed over the circuit board and the connector, said lid having a top plate that defines an opening through which the connector extends so as to define an exposed portion of the connector,
wherein the lid integrally includes a bead that protrudes upwardly from the top plate and extends at least partially around the opening so as to at least partially surround the exposed portion of the connector that extends from said opening; and,
wherein the bead includes an upwardly protruding portion that is relatively higher than any portion of the connector.
