## Abstract

A door hinge for an electrical cabinet includes a pathway for receiving an electrical harness, the hinge including two parts that are connected together and are rotatable with respect to one another about a pivot axis, the hinge including a duct that extends along the pivot and is designed to receive an intermediate section of the harness along the pivot axis, the duct including a longitudinal slot for the lateral insertion of the intermediate section of the harness into the duct while the intermediate section extends parallel to the duct. An electrical cabinet includes such a door hinge.

## Claims

### Claim 1

A door hinge for electrical cabinet having a path for receiving an electrical harness, the hinge comprising two parts connected to each other and rotatably movable relative to each other about a pivot axis, and a chute extending along the pivot axis and arranged to receive an intermediate section of the harness along the pivot axis, the chute comprising two portions, each disposed on a part of the hinge, the chute further comprising a longitudinal slot for laterally inserting the intermediate section of the harness into the chute, and fastening elements arranged to secure the intermediate section of the harness along the pivot axis.

### Claim 2 (depends on 1)

The door hinge according to claim 1, wherein the fastening elements are hooks.

### Claim 3 (depends on 1)

The door hinge according to claim 1, wherein the chute is in the form of a half-tube, and that the fastening elements are half-tube shells.

### Claim 4 (depends on 1)

The door hinge according to claim 1, wherein the hinge is arranged to receive an upstream section of the harness extending non-parallel to the pivot axis and a downstream section of the harness extending non-parallel to the pivot axis.

### Claim 5 (depends on 1)

The door hinge according to claim 1, wherein the fastening elements are arranged to secure an upstream section of the harness and a downstream section of the harness.

### Claim 6 (depends on 1)

The door hinge according to claim 1, further comprising two pivots on which the two parts of the hinge are arranged to be rotatably movable on the pivot axis, the pivots being located at opposite ends of the chute.

### Claim 7 (depends on 6)

The door hinge according to claim 6, wherein the two parts of the hinge are clipped together in the place where the pivots are located.

### Claim 8 (depends on 4)

The door hinge according to claim 4, further comprising two pivots on which the two parts of the hinge are arranged to be rotatably movable on the pivot axis, the pivots being located at opposite ends of the chute, wherein the hinge is arranged to receive the harness in such a way that the upstream section of the harness and the downstream section of the harness respectively join the intermediate section of the harness between the two pivots.

### Claim 9 (depends on 1)

An electrical cabinet comprising a fixed part, a door, an electrical harness and the door hinge according to claim 1, the door being mounted to the fixed part of the electrical cabinet via the hinge, the harness comprising an upstream section of the harness extending non-parallel to the pivot axis, then an intermediate section of the harness received in the chute and extending along the pivot axis, and then a downstream section of the harness extending non-parallel to the pivot axis.
