Connection structure for power conversion device
Provided is a connection structure for a power conversion device to be mounted in a vehicle, including: a casing of the power conversion device; an electric connection part, which is to be mechanically connected to the casing, and is configured to electrically connect the power conversion device and an external device to each other; and an electric conductor configured to electrically connect the power conversion device and the electric connection part to each other, wherein the casing and the electric connection part are mechanically connected to each other through intermediation of an anti-vibration structure, and wherein the electric conductor has such flexibility as to be able to follow a relative displacement between the casing and the electric connection part.
1. A connection structure for a power conversion device to be mounted in a vehicle, comprising:
a casing of the power conversion device;
an electric connection part, which is to be mechanically connected to the casing, and is configured to electrically connect the power conversion device and an external device to each other; and
an electric conductor configured to electrically connect the power conversion device and the electric connection part to each other,
wherein the casing and the electric connection part are mechanically connected to each other through intermediation of an anti-vibration structure,
wherein the electric conductor has such flexibility as to be able to follow a relative displacement between the casing and the electric connection part, and
wherein the electric connection part has a waterproof structure, which is arranged between the casing and the electric connection part and encircles the electric conductor, and is configured to achieve close contact between the casing and the electric connection part.
2. The connection structure for the power conversion device according to claim 1 , wherein the waterproof structure is a packing with flexibility, such as to be able to follow the relative displacement between the casing and the electric connection part caused by an external force.
