Description

Field of the invention

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

Prior art

It is known to use a connection box to an optical network for connecting optical cables from a wide area network to multiple consumption locations. The connection cabinet thus comprises optical connectors separating the fibers coming from the optical cables so that the fibers are then respectively led to their consumption locations. The cabinet includes one or more optical modules that must be accessible at the time of installation or during maintenance operations. Each module must be able to pivot around a corresponding hinge so that the back is accessible.

One possibility of arrangement is to horizontally align two optical modules in the connection cabinet. To facilitate the 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 requires designing a large number of parts constituting the optical modules since some parts are suitable only for the first type or only the second type of optical module.

The present invention aims to solve all or some of the disadvantages mentioned above.

DESCRIPTION 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; extending along a connection plane and having a reception location for optical connectors, the facade comprising a first end portion and a second end position opposite to the first end portion with respect to a third axis defined in the connection plane; facade being arranged to cooperate with the plate in a first cooperation position in which the first end portion cooperates with the plate and also a second cooperation position in which the second end portion cooperates with the plate, the third axis being transverse to the first axis and the second axis in first cooperation position and also in second position of cooperation.

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

The facade of the optical module is therefore suitable for the right side and the left side 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 locking 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 locking 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 the second cooperation position.

According to one aspect of the invention, the locking 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 according to the second axis in first cooperation position and also in second cooperation position.

This arrangement makes it possible to assemble the tray and the facade easily. Indeed, it is sufficient to slip the facade between the profiled faces to reach the first cooperation position or 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 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 wherein 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 according to the second axis in first position of cooperation and also in second position of cooperation.

This arrangement makes it possible to block the base plane in an easy manner in the first cooperation position and in the second cooperation position, the concave shape allowing locking 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 the construction and allow easy assembly both in first cooperation position and 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 with respect to a right axis or a left axis of the optical module, the sides being reversed.
