Description

Field of the invention

The present invention relates to an optical module for a cabinet for connection to an optical network.

Prior art

It is known to use a cabinet for connection to an optical network for the connection of optical cables coming from a wide area network to several consumption locations.

The connection cabinet thus comprises optical connections separating the fibers coming from the optical cables so that the fibers are then routed respectively to their consumption locations.

The cabinet includes one or more optical modules which must be accessible during installation or during maintenance operations. Each module must be able to pivot around a corresponding hinge so that the rear is accessible.

One possible arrangement is to align two optical modules horizontally in the connection cabinet. To facilitate connections, the hinges of the optical modules must be close to each other, that is to say between the two optical modules. The optical modules are thus asymmetrical.

It is therefore necessary to have a first type of optical modules with a hinge on the left and a second type of optical modules with a hinge on the right.

This situation makes it necessary to design a large number of parts constituting the optical modules since certain parts are suitable only for the first type or only for the second type of optical module.

The present invention aims to solve all or part of the drawbacks mentioned above.

Statement of the invention

To this end, the present invention relates to an optical module for a connection cabinet comprising:

- a plate extending along a base plane defined by a first axis and a second axis transverse to the first axis,

- a facade extending along a connection plane and having a receiving location for optical connections, the facade comprising a first extreme portion and a second extreme position opposite the first extreme portion relative to a third axis defined in the plane of connection, the facade being arranged to cooperate with the plate in a first cooperation position in which the first extreme portion cooperates with the plate and also in a second cooperation position in which the second extreme portion cooperates with the plate, the third axis being transverse to the first axis and to the second axis in the first cooperation position and also in the second cooperation position.

This arrangement makes it possible to use a single facade which can be used in the first cooperation position for rotation about a right axis and in the second cooperation position for rotation around a left axis.

The front of the optical module is therefore suitable for the right and left part of the connection cabinets, the axis of rotation of the optical module being in the center of the connection cabinet.

According to one aspect of the invention, the optical module comprises a blocking system arranged to block the facade along the first axis and along the second axis in the first cooperation position and also in the second cooperation position.

In other words, the blocking system prevents movement of the facade along the first axis and along the second axis that the cooperation between the facade and the plate is in the first cooperation position or in the second cooperation position.

According to one aspect of the invention, the blocking system has a first profiled face and a second profiled face extending transversely to the base plane, the first profiled face and the second profiled face being arranged to block the facade along the first axis. and along the second axis in the first cooperation position and also in the second cooperation position.

This arrangement makes it possible to assemble the plate and the facade easily. In fact, it suffices to slide the facade between the profiled faces to reach the first cooperation position or the second cooperation position.

According to one aspect of the invention, the first profiled face and the second profiled face are symmetrical with respect to a central plane extending transversely to the base plane.

This arrangement makes it possible both to simplify the plate because it can be designed so as to be substantially symmetrical with respect to the central plane and at the same time to standardize additional parts located near the two profiled faces.

According to one aspect of the invention, the first profiled face comprises a first concave portion and in which the second profiled face comprises a second concave portion, the first concave portion and the second concave portion being arranged to block the facade along the first axis and along the second axis in the first cooperation position and also in the second cooperation position.

This arrangement makes it possible to block in the basic plane easily in the first cooperation position and in the second cooperation position, the concave shape allowing blocking along the first axis and along the second axis.

According to one aspect of the invention, the locking system and / or the plate is symmetrical with respect to the central plane. This arrangement simplifies construction and allows easy mounting both in the first cooperation position and in the second cooperation position.

According to one aspect of the invention, the facade is symmetrical with respect to an intermediate plane transverse to the connection plane.

This arrangement makes it possible to obtain exactly the same spatial configuration for a rotation relative to a right axis or a left axis of the optical module, the sides being inverted.

Thus, it is possible to standardize the parts annexed to the plate and to the facade according to the desired assembly in the first cooperation position or in the second cooperation position.

This arrangement makes it possible to use a single square that the fixing amount is placed on the left or on the right of the plate: for a change of side, it is enough to tilt the anchoring square around the reversibility plane to reverse the first anchor wall and the second anchor wall and also the direction of extension of the fixing wall.

Thus, a cabinet with the left upright and an identical right upright can receive the optical module for mounting with an anchor pin to the left or to the right.

According to one aspect of the invention, the anchoring bracket comprises a guide wall connecting the first anchoring wall and the second anchoring wall.

This arrangement allows the guiding of optical cables from inside the connection cabinet to the plate which is movable in rotation. The cables extend along the guide wall which is fixed and are thus held in position during the rotation of the plate.

The optical module 3 comprises a plurality of cassettes 61 provided for the circulation and / or splicing of optical fibers. Each cassette 61 is arranged to be rotatably mounted on the plate 13 or on a mounting element on the plate 13. The rotation is defined between an orientation substantially parallel to the base plane 15 and an orientation transverse to the base plane 15.
