    专利说明:

    [0001] The invention relates to an assembly comprising two pipe elements mounted with an interface gasket. Within certain large structures, such as for example aircraft, there are several zones in which different fluids transit, through various conduits. Some of these areas are particularly sensitive due to the nature of the fluid flowing through them, and therefore need special attention in terms of safety. Thus, the area of an aircraft comprising the fuel tank and the associated ducts, must be designed to prevent leakage of fuel or other fluids, as well as the production of unwanted electrical arcs.
    [0002] The assemblies according to the invention make it possible to solve these two problems in a safe and stable manner, being designed to avoid degrading over time. The invention relates to an assembly comprising a first pipe element and a second pipe element, said first element 20 being mounted in said second element by means of at least one interface seal adapted to come into contact with said elements. According to the invention, the gasket, the first pipe element and the second pipe element are current conducting, said gasket being overmolded in one of said elements so as to be in electrical contact with said element. In this way, the seal has a dual function: seal between the two pipe elements so as to prevent leakage of a fluid that would be present in at least one of the two elements and, discharge electric currents, for example due to static electricity, and potentially being created between the two pipe elements. In addition, being molded into one of the two pipe elements, the seal thus has a positional stability, avoiding it to move and / or deform during assembly or over time, to the point of not being able to ensure its sealing function. According to a possible characteristic, the first element is able to penetrate into the second element so that said elements have a covering zone, said seal being placed in said zone while being in contact with the element in which it is not overmolded. . According to a possible characteristic, the seal extends at least partially along the circumference of the overlap zone. According to one possible characteristic, the seal is made of plastic loaded with carbon black. According to one possible characteristic, the seal is overmolded in a groove of the outer surface of the first pipe element. According to one possible characteristic, the seal is overmolded in an annular groove of the inner surface of the second pipe element.
    [0003] According to one possible characteristic, the groove has a bottom hollowed by a central groove extending over the entire length of said groove. According to a possible characteristic, the overmolded seal emerges from the groove so as to define a protruding bead. According to one possible feature, the gasket is hot-molded in the first or second pipe element, so that said gasket is directly in electrical contact with the element in which it is overmolded.
    [0004] According to a possible characteristic, the seal is overmoulded in the first or second pipe element via a conductive adhesive, so that said seal is in electrical contact with the element in which it is overmolded.
    [0005] According to a possible characteristic, the first element is a tube for conveying a liquid fluid, the second element being a hollow mechanical connector, and said tube being driven into said connector. According to one possible feature, the tube is in one piece and is made of a material to be selected from a plastic with carbon black, fiberglass with carbon black, a mixture of fiberglass and plastic with black of carbon, and a metal. According to one possible feature, the connector is made of a material to be selected from a plastic with carbon black, fiberglass with carbon black, a mixture of fiberglass and plastic with carbon black, and a metal. Another object of the invention is an aircraft comprising an assembly according to the invention. Another object of the invention is a method of mounting a first piping element in a second piping element by means of at least one interface seal. According to the invention, said first pipe element, said second pipe element and said gasket are current-conducting and said at least one gasket is overmolded in at least one of said elements so as to be in electrical contact with said gasket. minus one element, said method comprising a step of introducing the first piping element into the second piping element so as to position said at least one seal in electrical contact with the other element. According to a possible characteristic, an overlap zone is created between the first and the second piping element during said introduction step, the seal being placed in said zone in contact with the element in which it is not molded. Another object of the invention is a pipe element. According to the invention, said element is electrically conductive and has at least one interface seal which is electrically conductive, said seal being overmolded in said element so as to be in electrical contact therewith. The following is a detailed description of two possible embodiments of a mounting device according to the invention, with reference to FIGS. 1 to 5. FIG. 1 is a perspective view of an assembly according to FIG. FIG. 2 is a longitudinal sectional view of an assembly according to a possible embodiment of the invention; FIG. 3 is a longitudinal sectional view of a joint molded in a tube of the assembly; FIG. 4 is a partial perspective view of the tube of the assembly illustrated in FIG. 2; FIG. 5 is a longitudinal sectional view of a tube mounted in a connector according to another embodiment; possible embodiment of an assembly according to the invention. In order to eliminate any ambiguity, it should be noted that the connector is not an electrical connector in the conventional sense of the term, but a mechanical receptacle capable of receiving the end of a tube. Referring to FIG. 1, a possible embodiment of an assembly according to the invention comprises a first pipe element in the form of a fuel delivery pipe 1, and a second pipe element under the form of a mechanical connector 2, implanted in the structure 3 of an aircraft. This tube 1 is comparable to a hollow cylinder monoblock, and is made of a resistive material, such as for example a metal or a mixture of thermoplastic polymer and glass fiber loaded carbon black. The connector 2 is cylindrical and is preferably made of metal or a plastic charged with carbon black. It should be noted that said tube 1 and said connector 2 are electrical current conductors. The internal diameter of the connector 2 is greater than the external diameter of the tube 1, so that said tube 1 can be mounted in said connector 2 by depression. The connector 2 has an end 12, which is secured to the structure, and an opposite free end 14, adapted to receive the fuel delivery tube 1. Referring to FIGS. 2, 3 and 4, a possible embodiment of an assembly according to the invention comprises a seal 4 overmolded in the fuel delivery tube 1, at one of its 5 zones. end.
    [0006] More specifically, the tube 1 has at said end zone 5, an annular groove delimited by two annular flanges 6, projecting from the outer surface 8 of said tube 1. One of said flanges 6 is flush with the end 1. The groove extends 360 ° around the tube 1 and has a cylindrical bottom hollowed in the wall of the tube 1, by an annular central groove 9 extending over the entire length of said groove. The seal 4 is electrically conductive and may, for example, be made of a plastic charged with carbon black. Once the seal 4 has been overmolded in the groove of the tube 1, it protrudes from the two flanges 6.7 delimiting said groove, occupying the entire volume of the central groove 9 and that located between said edges 6,7. It thus creates a bead, widening locally and radially, the end zone 5 of said tube 1. The central groove 9 is designed to increase the contact area between the seal 4 and the tube 1. In this way, the seal 4 is found firmly secured to the tube 1, and the electric current can easily pass between said tube 1 and said seal 4.
    [0007] However, although the presence of this groove 9 improves the conditions of realization of an assembly according to the invention, it is not essential for such an embodiment.
    [0008] The seal 4 is deposited in the groove of the tube 1, so that it is in electrical contact with said tube 1. To achieve this result, said seal 4 can: either be directly molded hot in the groove of In fact, in this case, the contact between said gasket 4 and said tube 1 is sufficiently large to ensure satisfactory electrical contact between these two elements 1, 4 or to be overmoulded at a lower temperature in said groove, after which a thin layer of conductive adhesive has been deposited in said groove. Indeed, this conductive adhesive 10 will contribute to improving the contact conditions between the seal 4 and the tube 1 and thus allow to achieve electrical contact between these two elements 1,4. Referring to Figure 2, once the seal 4 has been overmolded satisfactorily in the throat of the tube 1, the tube 1 is routed to the connector 2 fixed, so as to present in front of said connector 2, the zone d end 5 having the seal 4. The tube 1 is then pressed inside the connector 2 fixed by this end zone 5 in the direction indicated by the arrow 13 shown in Figure 2. The mounting of the tube 1 in the connector 2 generates a zone of overlap between these two elements, providing a free space 15 between the outer surface 8 of said tube 1 and the inner surface 16 of said connector 2. During the phase of insertion of the tube 1 into the connector 2, the seal 4 is found in this overlap zone and comes into close contact with the inner surface 16 of said connector 2. By means of these different mounting phases, a possible embodiment of an assembly according to the invention is thus obtained, said assembly e being constituted by a tube 1 and a mechanical connector 2, said tube 1 being inserted partially into said connector 2 by means of an interface seal 4 overmolded in said tube 1.
    [0009] Referring to FIG. 5, according to another possible embodiment of an assembly according to the invention, the seal 104 is overmolded in a groove of the connector 102, under the same conditions as those described above, when said seal 4 is overmolded in a groove of the tube 1. For this embodiment, the groove is annular and is delimited by two annular flanges 106, 107 projecting from the inner surface of the connector 102. One of said flanges 106 comes flush with the free end of the connector 102. The groove extends 360 ° around the connector 2 and has a cylindrical bottom hollowed in the wall of the connector 102, by an annular central groove 109, extending over the entire length of said groove. Once the seal 104 has been overmolded in the groove of the connector 2, it protrudes two flanges 106, 107 delimiting said groove, occupying the entire volume of the central groove 109 and that located between said flanges 106, 107. It thus creates a bead, locally and radially reducing the section of the connector 102. The constituent materials of the seal 104, the connector 102 and the tube 101 are identical to those described for the previous embodiment. The overmolding techniques of the seal 104 in the groove of the connector 102 are also similar to those described for the previous embodiment.
    [0010] Once the seal 104 has been satisfactorily overmolded in the groove of the connector 102, the tube 101 is pressed inside the fixed connector 102 in the direction indicated by the arrow 113. The mounting of the tube 101 in the connector 102 generates a zone of overlap between these two elements, providing a free space 115 between the outer surface 108 of said tube 101 and the inner surface 116 of said connector 102. During the phase of insertion of the tube 101 into the connector 102, the seal 104 is found in this overlap area and comes into intimate contact with the outer surface 108 of said tube 101. Once the tube 1,101 mounted in the connector 2, 102, the seal 4,104 30 provides, on the one hand, a good seal between these two elements 1, 101 and 2, 102 by preventing fuel leakage, and secondly, a close electrical contact with said elements 1, 101 and 2, 102 so as to discharge parasitic electric currents and prevent the arcing. It is in fact assumed that the connector 2, 102 is grounded via the structure 3 to which it is secured, thus making it possible to discharge the parasitic electric currents. An assembly according to the invention has several advantages: it ensures an increased safety within the installation in which it is implanted, by preventing fuel leakage and the creation of electric arcs due for example to static electricity, it improves the reliability of the installation, it generates mass reductions, it makes it possible to implement a fuel delivery tube having a variable resistivity, as a function of the level of carbon injected into said tube.
