    MODULAR OVER-MOLDING TOOL FOR CABLE STRAND AND SHEATHING METHOD USING SUCH TOOLS TECHNICAL FIELD The invention relates to a modular over-molding tool for cable strand for sheathing according to complex three-dimensional configurations comprising sinuosities and derivations. The invention also relates to a sheathing process using this tool to form a harness by overmolding.
    The present invention relates to the field of electrical wiring, more particularly cladding in the field of aeronautics. In this area, the cables are assembled in a sheathed strand forming a harness by heat-shrinkable sleeves, open textile sheaths or corrugated thermoplastics.
    The cables are distributed to provide power and the electrical signal, via harness output leads, to the equipment of various avionics systems, in particular: landing gear actuators, air conditioning compressors, hydraulic pumps of pressurization, pumps for supplying kerosene to the engines, actuators for defrosting, ventilation, supplying the instrumentation facades of the cockpit system, avionics bay computers, technical equipment (galley ovens in English names -, lighting , ventilation) and domestic (entertainment screens) of the cabin system networks.
    STATE OF THE ART [0004] Many solutions for overmolding electrical wiring exist. Such solutions are known, for example from patent documents US 2008173479 or US 2015306800.
    However, these solutions are limited to overmolding of bus bars in an assembly with a harness, or overmolding of an assembly of cables on particular portions of harness. However, as the configurations become more and more complex, the overmolding of a harness in a more complex configuration, involving leads outside the overmolding plane, seems delicate or even impossible to achieve.
    However, if an overmolding can be conducted locally, as illustrated by the documents cited above, no application of overmolding of an electrical harness as a whole is suitable for the variable forms of the wiring paths: a simple overmolding in two dimensions require complex tooling due to the presence of branch branches on a harness hardened by this overmolding. In fact, the protection must be able to adapt simultaneously to two types of requirement: the geometric environmental constraints and the physical constraints of this environment (resistance to UV radiation, to shocks, to respect watertightness, etc.).
    [0007] Thus, electrical harnesses may require two-molding and / or three-dimensional.
    PRESENTATION OF THE INVENTION The main objective of the invention is to provide such an overmolding capable of following the final shape of the harness adapted to its environment, and therefore capable of following a three-dimensional morphology. To do this, the invention provides for surrounding the wiring to be sheathed with a tool made up of overmold half-elements, coupled adjacent and assembled in a complementary manner by means of straight and circular mechanical connections, to form a complete overmolding and sheathing from this overmolding.
    More specifically, the present invention relates to a modular overmolding tool of a strand of cables, intended to protect the strand and thus form a harness. Such an overmolding tool comprises complementary half-modules assembled in standard modules as well as branch modules in extension in the same median plane, the half-modules having the overall shape of a straight and bent block. Each half-module has an internal half-bore forming, with the half-bore of the complementary half-module, a cylindrical bore surrounding the strand along straight and bent sections, and a double cylindrical bore along sections of the bypass strand . In addition, the adjacent half-modules of consecutive modules are coupled together by contiguous and detachable mechanical connections.
    An additional advantage of this tool is to be able to end-to-end pre-standardized modules and therefore reusable to achieve other sheathing.
    According to preferred characteristics:
    - the bypass half-modules are so-called “2D” half-modules when the strand bypass extends in the same median plane as that of the adjacent standard modules, and so-called “3D” half-modules when the strand bypass extends in at least one direction outside this median plane of the adjacent standard modules;
    - the standard bent half-modules have their chamfered elbow edge;
    - the cylindrical internal bores and the overmolding modules extend in a shape chosen between a rectilinear shape, a bent shape, a straight bypass shape, a bent shape bypass and a terminal form of rear connection to a connector;
    - the half-modules of each module are identical and mechanically coupled in a median plane of symmetry separating the internal bore into two identical cylindrical half-bores;
    - two complementary half-modules of the same module are assembled by means of corresponding pins and imprints;
    - the detachable mechanical connections between two adjacent half-modules of two modules are direct coupling connections of the male / female type, in particular of the tenon and mortise type in the form of a “dovetail”, between two adjacent standard half-modules straight and / or angled and between a half-module of a standard straight and / or angled module and an adjacent half-module of “2D” branch, and are angular adaptation links with bayonets between a standard half-module or a half-module in “2D” bypass and an adjacent half-module in “3D” bypass;
    - bayonet connections are formed on male and female adapters coupled to half-modules by extending them with tenon connections
    I mortises and bayonet connections are integrated with other half-modules to form self-contained half-modules;
    the bayonet connections consist of a male connection, comprising a semi-circular insertion ring and a lug arranged in the middle of said ring, and of a female connection comprising a crenellated angular indexing cavity in which said ring is housed, and the male link lug;
    - the crenellated cavity has two faces called internal and external with respect to the male adapter, these faces being respectively provided with a boss and a complementary stamping between which the lug is held by clamping in angular position corresponding to an orientation “3D” half-modules and the shunt of the strand;
    - semi-circular adapter sleeves can be inserted into the cylindrical internal half-bores of the half-modules in order to adapt the diameter of the bore to different strand diameters.
    The invention also relates to a method of sheathing a strand of cables to form a harness by the use of the overmolding tool as defined above. This process includes the following successive steps:
    - develop a harness configuration from a strand of cables with rectilinear, curved and "2D" and / or "3D" parts;
    - select the standard straight and / or bent and "2D" and / or "3D" standard half-modules fitted with adapters, so that an assembly of these modules corresponds to the elaborate configuration;
    - couple the adjacent standard and “2D” half-modules around the corresponding parts of the strand and form a median plane of subsequent assembly of these half-modules with the complementary half-modules;
    - couple the "3D" adapters of the "3D" branch half-modules to the adjacent standard half-modules fitted with adapters around the "3D" leads of the strand;
    - assemble the “3D” adapters of the “3D” bypass half-modules complementary to the adapters of the standard half-modules and the “3D” bypass half-modules already mounted;
    - couple the standard complementary and bypass “2D” half-modules together and assemble them to the corresponding standard and bypass half-modules “2” around the corresponding parts of the strand;
    - injecting / calendering a primary sheathing material, chosen between a thermoplastic primary material, elastomer, thermoplastic elastomer and a silicone-based material, from injection orifices formed on modules to fill the gap between the bores of the overmolding and strand modules;
    - heat treatment of this primary material to form a protective sheath, and
    - remove the overmolding tool which surrounds the sheath thus formed by disassembling the modules and uncoupling the half-modules.
    The invention also relates to an aircraft equipped with at least one harness provided with a sheath produced by the process defined above.

    DETAILED DESCRIPTION With reference to the perspective view of FIG. 1, an exemplary embodiment of an overmolding tool 1 is presented. This tool 1 during assembly consists of first adjacent half-modules, a standard straight half-module 2a, a standard half-module bent at 90 ° 3a and a “3D” branching half-module 4a, mechanically coupled together . The upper faces 2s and 3s of the standard half-modules 2a and 3a define a median plane Pm of coupling with identical and complementary half-modules. The demimodules 2a and 4a generally have the shape of a straight block and the demimodule 3a the shape of a bent block, with the edge of the chamfered elbow 30.
    The use of half-modules separates a cylindrical internal bore
    - housing strand 10 after assembly with additional half-modules
    - in half-bores 9 and 9sd to accommodate the strand 10 along rectilinear sections, bent and bypass. The half-bores 9 of each standard half-module 2a and 3a extend in the generally rectilinear or curved direction of these standard half-modules.
    The half-bores 9 and 9sd of the "3D" bypass half-module 4a extend in two rectilinear and initially curved directions. The half-bore 9 and the bypass half-bore 9sd coming from the half-bore 9 make it possible to receive the strand 10 and its branch cable 11 which detaches therefrom at point 12. The bypass half-bore 9sd continues to progress in a manner straight along an axis Z'Z, perpendicular to the median plane Pm in the example illustrated or inclined relative to this plane in other parts of the strand 10.
    The adjacent half-modules 2a, 3a, 4a are coupled together by detachable mechanical connections of a first type, namely in this example by a direct male / female coupling system with dovetail with tenon 7a and mortise 7b (see also Figure 2). Then these half-modules 2a, 3a and 4a are assembled with the identical and complementary half-modules by means of pins 20 and corresponding imprints 21 or other direct connections.
    The coupling between the “3D” bypass half-module 4a and an adjacent standard half-module, like the bent half-module 3a in FIG. 1, is achieved by mechanical angular adaptation bayonet connections between male 40 and female 50 adapters. The adapters 40 and 50 constitute end pieces extending the half-modules 4a, 3a and previously coupled by dovetail (or more generally by tenons and mortises). This type of connection, called the second type, is presented more fully with reference to FIGS. 5 to 8. Prior to assembly by these connections of the second type, the adapters 40 and 50 are coupled to the half-modules 3a and 4a by mechanical connections. of the first type.
    FIG. 2 shows a perspective view of complementary half-modules to be assembled, namely standard straight half-modules 2a and 2b and “2D” bypass half-modules 5a and 5b to integrate a modular overmolding tool such as the tool in FIG. 1. The adjacent half-modules 2a and 5a on the one hand and 2b and 5b on the other hand are detachably coupled together by the tenons / mortises 7a, 7b for coupling at the tail d dove. Then the half-modules 2a and 5a are assembled to the complementary half-modules 2b and 5b by male / female coupling elements, pins 20 and imprints 21 in the example.
    The half-modules 5a and 5b mold a “2D” bypass of the strand 10 (cf. FIG. 1) by the bypass half-bore 92d which, coming from the half-bore 9, extends in the same plane as that- ci, this plane being parallel to the median plane Pm of assembly of the half-modules (cf. figure). It is in this sense that the half-modules 5a and 5b are qualified as a “2D” derivation, a derivation extending in the same two-dimensional plane (the plane Pm), while the half-bypass modules 4a (cf. 1) are of the “3D” type because they allow the extension of a derivation according to a third dimension with respect to the median plane Pm.
    The assembly of an overmolding tool such as tool 1 therefore consists, after having worked out the harness configuration suitable for electrical distribution, in selecting the standard straight half-modules 2a, curves 3a and in "2D bypass" »4a and« 3D »5a provided with male / female connection adapters, such as adapters 40 and 50. This selection makes it possible to construct the overmolding tool in a spatial configuration which corresponds to the configuration of the harness.
    The adjacent half-modules, such as the standard straight half-modules 2a, curve 3a and in "2D" branch 4a are then coupled around the parts of the corresponding strand 10 by detachable dovetail links 7a, 7b or equivalent. The upper faces 2s, 3s then form the median plane Pm of subsequent assembly of these half-modules with the complementary half-modules. The adapters 40, 50 of the “3D” branch half-modules 5a are coupled to the adapters 50, 40 of the adjacent standard half-modules 2a, 3a, where “3D” branches are provided around the parts of the corresponding strand 10.
    It is then necessary to assemble the “3D” bypass half-modules complementary to the adapters 50, 40 of the standard half-modules 2a, 3a, as well as to the “3D” bypass half-modules 5a already mounted by direct connections of the pawn 20 and footprint 21 type. Then, the standard complementary half-modules and "2D" bypass are coupled together and assembled with the corresponding standard half-modules 2a, 3a and "2D" bypass 4a , around the parts of the strand 10 which relate thereto.
    The view of Figure 3 shows in detail, according to the embodiment of Figure 1, a straight standard module 2 of cubic shape, composed of half-modules 2a and 2b, and a strand 10 received in the half cylindrical bore 9 extending transversely along a median. Also visible are the pins 20 and imprints 21, allowing a mechanical assembly of the half-modules 2a and 2b to form a module, as well as the mortises 7b for direct coupling in dovetail with an adjacent module.
    In the case of a strand 10 having “3D” leads such as the lead 11 outside the median plane Pm (see FIG. 1), the presence of “3D” male 40 and female 50 adapters in the tooling modular overmolding 1 can be integrated by molding as soon as the module is manufactured, as shown in FIG. 4, or added after construction, as illustrated in FIGS. 5 to 8.
    In the perspective view of Figure 4, the half-module 60 has an end face 52 forming a female "3D" adapter provided with a cavity 54, and an opposite end face 42 forming an adapter Male “3D” provided with an insertion ring 44. In this example, the “3D” adapters are integrated into the half-module 60 to form a single block. In addition, this half-module 60, as well as its complementary and identical half-module (not shown), comprises an adapter sleeve 61 semi-cylindrical. Sleeves 61 of different thicknesses, inserted into the internal half-bore 9 of the module 60, make it possible to match different strand diameters 10.
    The perspective views of Figures 5 and 6 respectively show the male "3D" adapter 40 (Figure 5), and the female 3D adapter 50 (Figure 6) to assemble. These “3D” adapters 40 and 50 include pins 20 and indentations 21 for assembly with complementary adapters and links forming a bayonet assembly. This assembly is carried out using a central lug 43 and end lugs 4B of a semicircular insertion ring 44 which is housed in a crenellated cavity 54 for angular indexing of the female adapter 50. Cutouts 55 and 55B are formed in the female adapter 50 to insert the lug 43 and the lugs 4B in the crenellated cavity 54.
    The crenellated cavity 54 is presented more precisely with reference to the sectional views of Figures 7 and 8 in the plane "P" of Figure 6: a so-called inner face "I" relative to the male adapter 40 (Figure 7), and a so-called external face “E” relative to this same male adapter 40 (FIG. 8). In these FIGS. 7 and 8 appear the mortises 7b for a dovetail coupling with the adjacent half-modules, as well as the pins 20 and indentations 21 for assembly with the complementary half-modules.
    It appears that the inner face "I" has a boss 54a, each bump 70 is separated from the next bump by an angular difference Δ. In this embodiment, the difference Δ is 15 °. On this inner face “I” also appears the cutout 55 for inserting the lug 43 of the male adapter 40 into the crenellated cavity 54 (cf. FIGS. 5 and 6).
    On the outer face "E" (Figure 8), extends a stamping 54b complementary to the boss 54a, and the recesses 80 of the stamping 80 are also separated by the same angular deviation Δ as the bumps 70 of the face internal "I" (see Figure 7).
    The lug 43 is thus maintained in the angular position between a bump 70 and a corresponding recess 80, with an angular pitch Δ, and the adapted value between the bumps 70 and the recesses 80 allows easy adjustment of the angular position d a male “3D” adapter 40 (cf. FIG. 5) to a female “3D” adapter 50 (cf. FIG. 6).
    The aliasing formed by the boss 54a and the stamping 54b of the cavity 54 of the female adapter 50 allows, by the suitable angular orientation of the lug 43 of the male adapter 40 to direct the "3D" branches »Of the modular overmolding tool depending on the harness configuration. Thus, the branch 11 of the strand 10 (cf. FIG. 1) can be oriented in a direction other than perpendicular to the median assembly plane Pm as a function of the orientation requirements of this branch 11 in the configuration of the strand 10.
    To complete the overmolding process, a sheath is formed between the bores 9 of the modules 2 (cf. FIG. 3) coupled and assembled all along the strand 10 by calendering of primary sheathing material from orifices d formed on modules. Then an appropriate heat treatment for this primary material is implemented. The primary material provides with this treatment a sheath material. In the example, the sheath is made of silicone, but other materials can be used (thermoplastic material, an elastomer, a thermoplastic elastomer, or the like). The overmolding tool 1 which surrounds the harness sheath thus formed is finally removed by disassembling the modules and uncoupling the half-modules.
    The invention is not limited to the embodiments described and shown. Thus, the half-modules of the same module can be assembled by other detachable assembly means than the system of pawns and imprints (clipping, hooking, etc.), and two modules can be linked by links mechanical tenons / mortises with ankles.
    Among other things, the modular overmolding according to the invention can integrate additional elements for installing the harness in the modules, for example harness supports in the environment, welding passage conduits, or gaskets. seal. The modules can then have a standard or adapted internal volume.
    In addition, the bent modules can form an angular sector different from 90 °, for example 30, 45 or 60 °. The modules and their internal bores can be modules and terminal bores taking a terminal form of rear connection to a connector (by coupling the module with a narrowing element or other adapter).
    Furthermore, the orientation pitch between two "3D" adapters can be different from 15 °.
    In addition, the invention can be applied to any harness outside the field of aeronautics (automotive, etc.).

    10 corresponding “2D” bypass (2a; 5a) around the parts of the strand (10);
    - injecting / calendering a primary sheathing material, chosen between a thermoplastic primary material, elastomer, thermoplastic elastomer and a silicone-based material, from injection orifices formed on modules to fill the gap between the bores ( 9, 9 2 d, 9 3D ) modules
    15 overmolding and the strand (10);
    - heat treatment of this primary material to form a protective sheath, and
    - remove the overmolding tool (1) which surrounds the sheath thus formed by disassembling the modules and uncoupling the half-modules (2a, 2b; 3a; 5a,
    20 5b; 4a; 60).
