    FIELD OF THE INVENTION
    The present invention relates to a union for optical fiber circuit and a method of connecting such a circuit to such a connection.
    STATE OF THE ART
    An optical fiber circuit generally comprises tubes which are connected to each other by union connectors and in which an optical cable consisting of a bundle of optical fibers extends. The set of tubes and fittings provides mechanical protection of the optical cable and facilitates the installation of the optical cable, the optical cable is generally introduced into the circuit after installation thereof and pushed along it in a flow of air under pressure.
    The fittings include union fittings and end fittings which, as their name implies, are respectively mounted between the ends and ends of the circuit.
    An intermediate coupling conventionally comprises a tubular body in the form of a straight cylinder having a first and a second independent shell whose interior is coated with a ribbed elastomeric coating. The first shell has at each of its two ends a C-shaped receiving portion for receiving a tube and holding it in position. When the tubes to be connected are placed in the reception portions of each end of the first shell, the second shell is presented on the first. The tubular body then delimits a junction channel between the tubes. Two C-shaped cleats are then engaged on each of the tubes and are slidable along each tube to then tighten the shells against each other. To this end, each shell comprises, along its open edges, a radially projecting portion forming a locking wedge. Each crampon comprises an internal frustoconical groove which engages with the locking wedges of the shells presented to one another. A translation of the crampons from the ends of the connector to the center thereof compresses the shells on the tubes, thus ensuring the maintenance of the tubes and their tight connection through the compression of the ribs of the elastomeric coating on the outer surface of the tubes.
    Such a coupling has many disadvantages, making its implementation particularly impractical, which is a source of many non-conformities including leaks. During the installation of the connection, it may be necessary to force the approximation of too distant tubes which requires the intervention of a second operator to secure the half shells because the two hands of the first operator are used to bring the tubes together . In case of misalignment of the tubes, the intervention of a second operator is also required, in particular to engage the spikes on the tubes and slide them on the fitting. The relative tightening of the shells of the fitting is a function of the force deployed by the operator during the sliding of the cleats on the fitting. Thus, in case of insufficient tightening, the sealing and the relative maintenance of the tubes are not effective and, in the case of excessive tightening, it causes a loss of elasticity of the crampons preventing effective maintenance of tubes, affecting the tightness of the junction of the tubes. In the case of extended optical fiber networks, the networks are pressurized at very high pressures - of the order of 15 bar - and the simple compression of the tube by the elastomeric coating is generally insufficient to maintain the tube. position when pressurizing the network.
    Finally, the connection consists of four independent parts to be dismantled and kept during the junc- tioning operations of the tubes. In the case of interventions in sensitive environments such as the food or nuclear industry, or constrained (small spaces), the parts can be lost and their dismantling difficult. Finally, the disassembly of this connection requires to make great efforts to separate the crampons.
    Since fiber optic circuits are received in ducts that also contain water pipes and gas pipes, it is necessary to prevent gas leakage, or a rise in odor or moisture, from occurring. propagate to the premises of the end user or to the technical premises of the telecommunications operator, premises which are reserved for the distribution of optical fibers. A specific union connection providing a sealed isolation of the two tubes is then required, increasing the number of elements to provide for an intervention.
    OBJECT OF THE INVENTION
    An object of the invention is to improve the reliability of a union, in particular by providing a connection and a simpler connection method.
    SUMMARY OF THE INVENTION For this purpose, there is provided a union connection for an optical fiber circuit comprising at least a first tube and a second tube in which an optical cable extends along a longitudinal axis, the connector comprising a tubular body. having a first shell and a second shell connected along one of their edge and provided with means of their solidarization relatively to one another. The tubular body comprises a first end provided with a first section for receiving an end portion of the first tube, and a second end comprising a second section for receiving an end portion of the second tube.

    DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
    With reference to FIGS. 1 to 3, the union connector according to the invention, generally designated 1, is intended for constituting an optical fiber circuit comprising a first tube 1000 and a second tube 2000 in which a optical cable 3000 consisting of a bundle of optical fibers.
    The connection 1 comprises a tubular body 20 of longitudinal axis X delimiting a stepped channel 50. The tubular body 20 comprises a first end 21 provided with a first cylindrical section 22 for receiving an end portion 1001 of the first tube 1000 of cylindrical shape, and a second end 23 comprising a second cylindrical section 24 receiving an end portion 2001 of the second tube 2000. The first and second sections 22 and 24 of the connector 1 have an inner diameter dl and d2 respectively substantially equal to the outer diameter D1 and D2 of the tubes 1000 and 2000. The first and second sections 22 and 24 respectively comprise two teeth 25 and 28 projecting respectively radially from the wall 27 of the first section 22 and the wall 30 of the second section. 24. As shown in FIG. 1, the tooth 25 of the first section 22 adopts a direction with respect to the longitudinal axis (X) which is opposite to the direction of the tooth 28. In other words, the tooth 25 is arranged relative to the tooth 28 so that a relative rotation of the connector 1 relative to one of the tubes 1000 or 2000 around the longitudinal axis (X) causes a relative translation along the longitudinal axis (X) of the tube 1000 and / or 2000 relative to the coupling 1. According to the representation of Figure 1, the tooth 25 of the first section 22 and the tooth 28 of the second section are arranged so that, during a relative rotation of the connector 1 relative to the first tube 1000 and the second tube 2000, the respective translations of the first tube 1000 and the second tube 2000 are in opposite directions.
    The stepped channel 50 extends between the first section 22 and the second section 24 and comprises successively a first reception section 51 of the end 1001 of the first tube 1000, a central housing 52 and a second reception section 53 of The end 2001 of the second tube 2000. The second host section 53 comprises a shoulder 54 projecting radially from the inner face of the second section 3 3 home. The central housing 52 comprises, here, a cylindrical portion 52.1 and a frustoconical portion 52.2. The stepped channel 50 is defined by a silicone sealing element 55 integral with the tubular body 20 and which forms a sealed channel between the first tube 1000 and the second tube 2000. The element 55 comprises respectively at each of its ends 55.1 and 55.2 a first and a second flange 56 and 57 intended to be respectively received in homologous grooves 31 and 32 of the tubular body 20.
    The tubular body 20 is separated into a first shell 20.1 and a second shell 20.2 in a plane comprising the longitudinal axis X, with the exception of the first section 22 and the second section 24 which are respectively separated into a first portion 22.1 and 24.1. in the form of C integral with the first shell 2.1 and a second portion 22.2 and 24.2 of complementary shape integral with the second shell 2.2. The shells 20.1 and 20.2 are connected along their respective edges 20.11 and 20.21 by a hinge 33 whose axis extends substantially parallel to the longitudinal axis (X). The first shell 20.1 is provided with two tabs 40 and 41 of clipping projecting tangentially from the inner face 20.12 of the first shell 20.1 and whose ends respectively comprise an anchor tooth 40.1 and 40.2. The second shell 20.2 comprises two anchoring windows 42 and 43 intended to receive the anchoring tabs 40 and 41. The shells 20.1 and 20.2 respectively comprise a notch 80 and 81 in the shape of a quarter of a sphere opening on the longitudinal edge opposite to the articulation 31.
    Each shell 20.1 and 20.2 respectively comprises a housing 20.13 and 20.14 in which are respectively overmolded two half-shirts 58 and 59. The half-shirts 58 and 59 are connected to one another by two flat links 60 and 61 ' extending from two points of the outer surface of the first and second flanges 56 and 57. The meeting of the first and second flanges 56 and 57 constitutes the sealing member 55. The shells 20.1 and 20.2 and the half-sleeves 58 and 59 are made of translucent or even transparent material which thus makes it possible to note the presence or absence of an optical fiber cable inside the connector 1.
    As visible in FIG. 3, the half-sleeve 58 comprises a first bead 62 projecting radially from the longitudinal edge of the half-sleeve 58 farthest from the hinge 31. This bead 62 is received in a peripheral groove 20.15 bordering the edge farthest from the hinge 33 of the housing 20.13. The bead 62 comprises a longitudinal lip 63 projecting from the junction plane (P) of the half-sleeves 58 and 59. The inner side 64 of the lip 63 is set back with respect to the inner surface of the half-sleeve. 58 and has a slope substantially parallel to a tangent to the half-jacket 58 considered at a point of the plane (P). The longitudinal edge of the half-sleeve 58 closest to the hinge 31 comprises a second bead 65 similar to the first bead 62 and received in a longitudinal groove 20.16. The second bead 65 comprises a lip 66 identical to the lip 63.
    Similarly, the half-sleeve 59 comprises a third bead 72 projecting radially from the longitudinal edge of the half-sleeve 59 farthest from the hinge 31. This bead 72 is received in a peripheral groove 21.15 bordering the furthest edge of the articulation 31 of the housing 21.13. The bead 72 comprises a longitudinal lip 73 projecting from the plane of junction (P) of the half-sleeves 58 and 59. The outer edge 7 4 of the lip 73 is set back relative to the outer surface of the half sleeve 58 arranged to come into contact with the slope 64 of the bead 63 when the first and second shells 20.1 and 20.2 are closed one over the other. The longitudinal edge of the half-sleeve 59 closest to the joint 31 comprises a bead 75 similar to the bead 73 and received in a longitudinal groove 21.16. The bead 75 comprises a lip 76 identical to the lip 73.
    A sealing gasket 5 intended to be mounted on the optical cable 3000 and to be contained in the tubular body 20 is shown in FIGS. 4 to 6. The latter is in the form of a section or bead of rectangular section ( small section 5.1 shown in Figure 4) wound, in a winding direction to the left, three successive disjoint helical turns 5.2, 5.3 and 5.4 about a longitudinal axis to form a tubular element of large circular section 5.5 (considered according to a plane perpendicular to the longitudinal winding axis of the turns). The end turns 5.2 and 5.4 are disjoint, i.e. they are not in contact with the other turns of the sealing element, and are truncated to form end faces 5.6 and 5.7 planes extending substantially perpendicular to the longitudinal axis of the sealing member.
    The connection of the connector 1 to a first tube 1000 and a second tube 2000 in which extends an optical cable 3000 of an optical fiber circuit will now be described with reference to FIGS. 7 to 13.
    The first and second shells 20.1 and 20.2 constituting the tubular body 20 are separated (FIG. 7) and presented facing each other around the optical cable 3000. They are then secured around the optical cable 3000 (FIG. so that it extends through the connector 1. The end 1001 of the first tube 1000, is engaged in the first section 22 of the first end 21 of the connector 1 by a relative translation of the tube 1000 relative to the connection 1 along the longitudinal axis (X) (Figure 9). The open profile C of the first section 22 allows its elastic deformation during the introduction of the first tube 1000. The teeth 25 and 26 penetrate into the tube 1000 and maintain it in position relative to the connection 1. The 2001 end of first tube 1000, is then engaged in the second section 24 of the second end 23 of the connector 1 by a relative translation of the tube 2000 relative to the connector 1 along the longitudinal axis (X) (Figure 10). The open profile C of the second section 24 allows its elastic deformation during the introduction of the second tube 2000. The teeth 28 and 29 enter the tube 2000 and maintain it in position relative to the connection 1.
    In order to establish a tight connection of the first tube 1000 and the second tube 2000, a relative rotation of the connector 1 relative to the first tube 1000 and the second tube 2000 is performed around the longitudinal axis (X) (Figure 11). The direction of this rotation is chosen so as to cause a longitudinal translation of the first tube 1000 and the second tube 2000 towards each other inside the connector 1 by means of the respective orientations of the teeth 25, 26 and 28, 29 As can be seen in FIG. 12, this rotation brings the end 2001 of the tube 2000 against the shoulder 54 of the second section 53. This same rotation brings the end 1001 of the tube 1000 into contact with the inside face of the frustoconical portion 52.2 of the central housing 52 defined by the sealing element 55. An additional rotation of the connector 1 relative to the first tube 1000 and the second tube 2000 causes a compression of the ends 1001 and 2001 respectively against the shoulder 54 of the central housing 52 and against the internal face of the frustoconical portion 52.2, establishing a tight connection of its ends with the sealing element 55 which defines the central housing 52.
    The union connector 1 can also be used to seal the end 1001 of a tube 1000. This method comprises the following steps: - engage the end 1001 of the first tube 1000 in the first section 22 of reception fitting; - Pass an optical cable 3000 in the first tube 10001 and in the union connector 1 (Figure 13); separating the first shell 20.1 from the second shell 20.2 (Figure 14), for example by introducing a finger in the space defined by the notches 80 and 81 to exert a lever effort on the shells 20.1 and 20.2; - Place the seal 5 around the optical cable 3000 (Figure 15); presenting the second shell 20.2 facing the first shell 20.1 so that the sealing gasket 5 is received in the conical portion 52.2 of the central housing 52 (FIG. 16); - Secure the first shell 20.1 and the second shell 20.2 between them; applying a rotational movement of the union connector 1 relative to the first tube 1000 in order to move the end 1001 of the first tube 1000 in the union connector 1 until it comes to compress the sealing gasket 5 between the end 1001 of the tube 1000 and the frustoconical portion 52.2 of the central housing 52 (Figures 18-19).
    A union connection is then obtained for an optical fiber circuit making it possible to also seal the internal channel. The use of a single device to perform both types of connection (union and end) reduces the number of part numbers required for an intervention and allows a larger scale production of this connection, resulting in a lower costs by economies of scale.
    It will be noted that when they are connected, one of the tubes abuts against the frustoconical surface 52.2 while the other tube abuts against the shoulder 20.17. This frustoconical surface and this shoulder constitute abutments to the depression of the tubes. These stops define a passage section at least equal to an inner passage section of the tube.
    Elements identical or analogous to those previously described will bear a numerical reference increased by one hundred in the following description of a second embodiment of the invention.
    Referring to Figure 19, the connector 101 comprises a tubular body 120 separated into two shells 120.1 and 120.2 in which are molded the two half-sleeves 158 and 159 constituting the sealing element 155. This sealing element 155 comprises a frustoconical portion 152.2 opening on a receiving section 153 of the end 2001 of the second tube 2000. The receiving section 153 comprises a shoulder 154 projecting radially from the inner face of the receiving section 153. The outer face of the frustoconical portion 152.2 comprises a flange 156 intended to be received in a homologous groove 131 of the tubular body 120 in order to lock in position the sealing element 155 in the tubular body 120.
    The connection of the connector 101 to a first tube 1000 and a second tube 2000 is made according to the same method as that previously described. As can be seen in FIG. 20, sealing of the junction of the first tube 1000 with the coupling 101 is by compression of the end 1001 of the first tube 1000 against the frustoconical portion 152.2 of the sealing element 155. the junction of the second tube 2000 with the connector 101 is made by compression of the end 2001 of the second tube 2000 against the shoulder 154 of the sealing element 155.
    The frustoconical portion 152.2 and the shoulder 154 constitute abutments at the recess of the tubes. These stops define a passage section at least equal to an inner passage section of the tube.
    Elements identical or analogous to those previously described will bear a numerical reference augmented by two hundred in the following description of a third embodiment of the invention.
    Referring to Figure 21, the connector 201 comprises a tubular body 220 separated into two shells 220.1 and 220.2 in which are molded the two half-sleeves 258 and 259 constituting the sealing element 255. This sealing element 255 presents a symmetry along a radial plane. 1 / sealing member 255 comprises a first frustoconical portion 270 and a second frustoconical portion 271 connected to one another by their ends 272 and 273 of smaller diameter. The free ends 274 and 275 of larger diameter respectively of the first and second frustoconical portions 270 and 271 respectively comprise a flange 256 and 257 projecting radially from their outer face. These flanges 256 and 257 are intended to be received in homologous grooves 231 and 232 of the tubular body 220 in order to lock in position the sealing element 255 in the tubular body 220.
    The connection of the connector 101 to a first tube 1000 and a second tube 2000 is made according to the same method as that previously described. As can be seen in FIG. 22, the sealing of the junction of the first tube 1000 with the coupling 201 is done by compressing the end 1001 of the first tube 1000 against the frustoconical portion 270 of the sealing element 255. sealing the junction of the second tube 2000 with the connector 201 is by compression of the end 2001 of the second tube 2000 against the frustoconical portion 271 of the sealing member 255 (Figure 23).
    It will be noted that during their connection, the tubes abut against the frustoconical surfaces 270, 271. These frustoconical surfaces constitute abutments at the recess of the tubes. These stops define a passage section at least equal to an inner passage section of the tube.
    Of course, the invention is not limited to the embodiments described but encompasses any variant within the scope of the invention as defined by the claims.
