Abstract
The invention concerns an electrical cabinet (1) including a housing (2), a door (3) and a hinge (4). The housing and the door support electric wires which are each routed from an electrical component located inside an electrical equipment compartment (11) formed by the housing towards the outside of the compartment to be connected to a corresponding electrical connector (17). Therefor, according to the invention the electric wires are routed through the hinge which is itself connected to the electrical connector. The hinge forms at least one passage orifice (18, 19) guiding, the electric wires from inside the compartment towards the outside of the compartment while directing them towards the electrical connector.
Claims17
1- Electrical cabinet (1) comprising:
- an electrical housing (2) internally forming a compartment of electrical equipment (11),
- a door (3) for closing this compartment,
- a hinge (4) formed by a first linkage means and by a second linkage means (14), the first linkage means being fixed to the housing, the second means being fixed to the door, the first means and the second means being articulated about a rotation axis (16) of the hinge,
- at least one set of electrical components installed on the door and/or within the compartment, and
- electrical wires (5) connected to the electrical components, characterized in that:
- the linkage means are pierced with a passage hole through which the electrical wires are routed, the passage hole being formed longitudinally relative to an axis (29) of insertion of the electrical wires through the hinge, the insertion axis being an axis perpendicular to the rotation axis.
2- Cabinet according to claim 1, characterized in that each of the electrical wires is shaped as a loop whose plane is perpendicular to the axis of the hinge.
3- Cabinet according to claim 1, characterized in that the electrical wires are presented in sheets of adjacent wires, the plane of these sheets is perpendicular to the axis of the hinge, wires of these sheets having curvatures, in this plane, in both senses.
4- Cabinet according to claim 3, characterized in that the electrical wires of a sheet are held through the hinge by an elastic holding element (40) that envelops them.
5- Cabinet according to claim 1, characterized in that the set of components is installed inside the door, facing the compartment.
6- Cabinet according to claim 1, characterized in that the set of components is installed outside the door.
7- Cabinet according to claim 1, characterized in that it comprises a connector fixed to one of the linkage means, preferably connectors fixed to each of the linkage means.
8- Cabinet according to claim 7, characterized in that
- each electrical wire has a first end and a second end, the first end being distant from the connector while the second end is close to the connector, and
- a retention means (24) for the second end of the wire is interposed between the connector and the linkage means linked to the connector, this retention means fixedly holding in position the second end of the wire facing the connector during an electrical connection or disconnection of the connector relative to a matching connector.
9- Cabinet according to claim 8, characterized in that the retention means forms a block of elastic material pierced with a multitude of holes evenly distributed relative to one another, each of the holes being formed along an axis perpendicular to the axis of rotation of the hinge, and each of the holes being designed to be crossed by an electrical wire.
10- Cabinet according to claim 8, characterized in that the retention means forms a cable-clamp device compressing the wires perpendicularly to an axis (29) of insertion of the wires in the linkage means against the housing or against the door.
11- Cabinet according to claim 1, characterized in that the first linkage means and the second linkage means each form a part, one identical to the other.
12- Cabinet according to claim 1, characterized in that the first means and the second means each form a part coming from a molding of an insulator material.
13- Method for mounting an electrical cabinet according to claim 1, characterized in that it comprises the following step:
- inserting the electrical wires through the hinge perpendicularly to the rotation axis.
14- Mounting method according to claim 13, characterized in that it comprises the following steps:
- fixing a first end of the electrical wire to an electrical connector, and,
- fixing a second wire end to an electrical component.
15- Method according to claim 13, characterized in that it comprises the following step:
- grouping together several electrical wires through the hinge in enveloping them by means of a holding element (40) to hold the wires taut along an axis perpendicular to the rotation axis of the hinge.
16- Method according to claim 13, characterized in that it comprises the following step:
- interposing a retention means (24) for the electrical wires between an electrical connector and the hinge.
17- Method according to claim 16, characterized in that it comprises the following step:
- inserting the ends of electrical wires through the retention means.
