Dl SPOSI Tl F OF VOTING PI MODULES FROM TELECOMMUNI CATI ON OPTI QUE ΕΝ ΜΑΤΙ ERE PLASTI QUE

The invention relates to a device for pivoting optical telecommunication modules made of plastic.

Such a known device which can be made of plastic is described in patent document WO 2006/088931. It comprises a mounting frame intended to receive a plurality of optical telecommunication modules, a plurality of plates pivotally supported to provide individual access to the modules, each plate having a holding portion for receiving and maintaining the modules. A tube is attached to each plate which acts as a pivoting joint by passing a cylindrical bar through this tube.

The design of these plates must therefore be specific, depending on whether the modules are intended to be arranged with a pivot axis to the right or to the left in front view, or in other words with a clockwise or counterclockwise rotation.

However, if it is relatively easy to manufacture different metal modules, and possibly in reduced quantity, the development of plastic modules requires the production of corresponding molds, relatively complex and expensive, which it is detrimental to produce for the production of limited quantities of modules.

The invention solves this problem by proposing a device for pivoting optical telecommunication modules in plastic material of standardized manufacture and easy assembly.

To do this, the invention provides a device for pivoting optical telecommunication modules made of plastic material capable of being supported by a mounting frame capable of supporting for each module a support piece comprising at least a first pivoting arrangement, characterized in that than

said support piece is symmetrical with respect to its longitudinal plane and is capable of being fixed laterally on at least one profile of said mounting frame,

- Each said module comprises two sets of at least one second pivoting arrangement cooperating with said first pivoting, lateral, one of which is linked to said one or to said first (s) pivoting arrangement (s) and

- Said sets of at least a second pivoting arrangement are symmetrical with respect to a central transverse plane of the module and capable of being linked one on the first pivoting arrangement (s) of a workpiece support mounted to the left of said plane or the other on the pivot (s) of a support piece mounted to the right of said plane.

The same module can thus be mounted with a pivot axis to the right or to the left in front view, or in other words with a clockwise or counterclockwise rotation.

This results in standardization and a reduction in the number of production orders. Storage is greatly facilitated.

In addition, assembly is facilitated in the field since the assembly of the module on the support piece can be carried out in the field. Thus, the installed product may only become with a pivot axis to the left or with a pivot axis to the right only during the installation phase. The decoupling of this support part and the module facilitates the installation.

Preferably, said sets of at least one second pivoting arrangement are capable of being clipped onto the first pivoting arrangement (s) of said support piece.

When the height of the module is reduced and equal to a standardized unit, the interior of the module has a bottom suitable for receiving a set of parts allowing the guidance and / or splicing and / or the reception of coupling systems and / or the storage of optical fibers, arranged so as to allow reversible mounting to the left or to the right of said plane.

When the height of the module is greater and equal to several standardized units, the interior of said module comprises a pivoting plate and capable of receiving a set of parts allowing the guidance and / or splicing and / or the reception of coupling and / or storage of optical fibers, arranged so as to allow reversible mounting to the left or to the right of said plane.

Advantageously, said first pivoting arrangement is a pivot and said second pivoting arrangement is a pivoting cavity.

Preferably, said support piece is capable of being fixed by clipping, on a said profile perforated with regularly evenly distributed vertically openings.

The assembly is also greatly facilitated by this clipping arrangement.

More specifically, said support piece may comprise at least two openings of the same distance as two said orifices of said profile and arranged opposite these orifices, a socket is clipped into each of these openings and a blocking pin is clipped in each socket inserted in each orifice and opening.

Advantageously, a latch is integral with said module on the side of its front face opposite to said pivot.

Advantageously, a system for fixing and taking up play is able to be secured to a profile of said mounting frame and receives said latch, in the closed position.

Thanks to this system for fixing and taking up play, the deflection which may appear between the two front ends of the module can be absorbed within the limit of 5 millimeters. The system also makes it possible to make up for any differences in spacing between the two front profiles of the mounting frame.

Said backlash fixing and adjustment system may include inclined backlash flaps.

Preferably, said latch comprises two locking elements cooperating by sliding with said inclined sides of the system for fixing and taking up play and cooperating by locking with two tabs of the system for fixing and taking up play.

Said system for fixing and taking up play is able to be fixed preferably by clipping, on said section perforated with holes regularly distributed vertically.

More specifically, said system for fixing and taking up play can comprise at least two openings of the same distance as two said orifices of said section and arranged opposite these orifices, a sleeve is clipped into each of these openings and a blocking pin is clipped into each hole and opening.

The invention is described below in more detail with the aid of figures representing only a preferred embodiment of the invention.

Although only one module is shown in the figures, a device for pivoting optical telecommunication modules generally comprises a plurality of superimposed pivoting modules.

Depending on the configuration, these modules can be higher or lower and contain a certain number of connections, cassettes, splicing arrangements, etc.

As illustrated in FIGS. 1 to 4, a device for pivoting optical telecommunication modules in plastic material, for example in polycarbonate reinforced with glass fibers, according to the invention comprises a mounting frame 1 supporting for each module a support piece 2 symmetrical with respect to its longitudinal plane and comprising a cylindrical pivot 3.

The module is shown here with a transparent cover.

The support piece 2 is here fixed laterally on two profiles

Each module 4 has two lateral pivoting cavities 4A, 4B, one of which is clipped onto the cylindrical pivot 3 of the support part 2.

A latch 6 is secured to the module 4 on the side of its front face opposite the pivot 3.
