## Abstract

A power conversion device includes a power conversion unit for converting input power to output power; a connector for making connection to outside; a wire connected to the connector on one side and having a terminal on another side; and a first electric component connected to the terminal, wherein the first electric component is provided so as to overlap the wire as seen in a direction perpendicular to an extending direction of the wire.

## Claims

### Claim 1

A power conversion device comprising:
a power converter to convert input power to output power;
a connector for making connection to outside;
a wire connected to the connector on one side and having a terminal on another side, wherein the wire is connected to the fuse by the terminal, and the terminal is connected to the wire by a crimp portion; and
a first electric component connected to the terminal, wherein
the first electric component is a fuse connected to the power converter,
the fuse is provided so as to overlap the wire as seen in a direction perpendicular to an extending direction of the wire,
the fuse is a tube-type fuse,
the wire is substantially straight as the wire extends from a connector of a harness to the crimp portion, and
a center axis of the fuse and the wire are substantially parallel to each other.

### Claim 2 (depends on 1)

The power conversion device according to claim 1, further comprising a cooler for cooling the first electric component, wherein
the cooler is provided so as to overlap the first electric component as seen in the direction perpendicular to the extending direction of the wire.

### Claim 3 (depends on 2)

The power conversion device according to claim 2, wherein
the first electric component is covered by insulation resin.

### Claim 4 (depends on 1)

The power conversion device according to claim 1, wherein
the first electric component is covered by insulation resin.

### Claim 5 (depends on 1)

The power conversion device according to claim 1, further comprising a second electric component, wherein
the second electric component is provided so as to overlap the wire as seen in the direction perpendicular to the extending direction of the wire.

### Claim 6 (depends on 5)

The power conversion device according to claim 5, wherein
the second electric component is mounted on a wiring board, and
the first electric component and the second electric component are arranged with the wire therebetween.

### Claim 7 (depends on 1)

The power conversion device according to claim 1, wherein the wire is at least of a length sufficient to permit holding the wire in a manufacturing process for crimping the crimp portion.
