## Abstract

A cable fixing structure of a fuel cell stack fixes together a connector housing containing a substrate and a flat cable joined to the substrate. The cable fixing structure includes a fixing part provided for the connector housing, and having a convexly curved surface, and a heat contraction tube configured to surround the flat cable and the fixing part, and press the flat cable against the convexly curved surface.

## Claims

### Claim 1

A cable fixing structure for fixing together a connector housing containing a substrate and a flat cable joined to the substrate,
the cable fixing structure comprising:
a fixing part provided for the connector housing, and including a convexly curved surface; and
a heat contraction tube configured to surround the flat cable and the fixing part, and press the flat cable against the convexly curved surface,
wherein the flat cable is electrically connected to a cell voltage detection terminal of each of power generation cells of a fuel cell stack; and
a connection terminal is joined to the substrate, and the connection terminal is configured to be electrically connected to a connector of a cell voltage detection device.

### Claim 2 (depends on 1)

The cable fixing structure according to claim 1, wherein the convexly curved surface is expanded toward the flat cable in cross section which is perpendicular to a direction in which the flat cable extends, in an area where the flat cable and the fixing part are overlapped with each other.

### Claim 3 (depends on 1)

The cable fixing structure according to claim 1, wherein, in a state where the flat cable is curved in an arc shape along the convexly curved surface over an entire width of the flat cable, the flat cable is sandwiched and held between the convexly curved surface and the heat contraction tube; and
part of the heat contraction tube covering the flat cable is curved along the flat cable curved in the arc shape.

### Claim 4 (depends on 1)

The cable fixing structure according to claim 1, wherein the fixing part includes a plate piece having the convexly curved surface on one side in a thickness direction.

### Claim 5 (depends on 1)

The cable fixing structure according to claim 1, wherein an adhesive layer is provided between the heat contraction tube and the flat cable.

### Claim 6 (depends on 1)

The cable fixing structure according to claim 1, wherein the convexly curved surface and the heat contraction tube are positioned outside the connector housing.

### Claim 7 (depends on 1)

The cable fixing structure according to claim 1, wherein the fixing part has a clearance surface extending from the convexly curved surface to the substrate, in a direction away from the flat cable.

### Claim 8 (depends on 1)

The cable fixing structure according to claim 1, wherein the connector housing includes a first cover and a second cover that are separated in the thickness direction of the flat cable; and
the substrate and the fixing part are provided at the first cover.

### Claim 9 (depends on 7)

The cable fixing structure according to claim 7, wherein the clearance surface comprises a curved surface continuous with the convexly curved surface.
