Definitions
- the invention relates to the layout and connection of electrical equipment boxes within complex structures such as aircraft.
- the assembly and connection of the various on-board electrical networks uses electromechanical boxes forming an on-board infrastructure for transporting electrical power and data.
- Electromechanical enclosures of this type are generally called “electrical equipment” when they are equipped with at least one interface connector and they provide protection for the electronic circuits they contain, such as power supply circuits. power supply or signal processing.
- This equipment must regularly be assembled or disassembled during the assembly phases of an aircraft, the reconditioning of an aircraft, or during simple maintenance phases. This equipment is also likely to be integrated into an existing installation.
- the wired interconnection links are first mounted on the structure of the aircraft. A conformity check of the addressing of the interconnected links is then carried out to ensure the consistency and safety in operation of the on-board network once powered up. It is only after this check that the electrical equipment is then put in place and connected to the wired interconnection network.
- the position of electrical equipment and wired interconnection links determines the lengths of cable required and the routes of these cables within the aircraft.
- the object of the invention is to improve the layout of the interconnection devices of the prior art.
- the invention relates to a mounting base for aeronautical electrical equipment comprising:
- first attachment means defining an attachment base
- second attachment means defining a bearing surface for holding the electrical equipment
- a storage housing arranged between the fixing base and the support face of the spacer, and comprising a first lateral opening
- a connector support arranged opposite the first side opening of the storage housing, and provided with a connector locking means.
- the invention relates to an aircraft comprising a wired interconnection network and electrical equipment connected to this network.
- at least one piece of electrical equipment is mounted on a fixing base as described above, this electrical piece of equipment being connected to the wired interconnection network by a cable, a portion of which is coiled in the storage housing.
- the invention relates to a method for configuring the physical architecture of the wired interconnection network of an aircraft, comprising the following steps:
- the method further comprises, before the step of mounting electrical equipment on the mounting base, a step of transporting the aircraft structure.
- the method further comprises an operation for moving the electrical equipment comprising the following steps:
- the mounting base, the aircraft, and the method according to the invention allow a modular configuration of the equipment and wired interconnection links.
- Each piece of electrical equipment can have, at its mounting base, an excess length of its connection cable, coiled securely and held in the cable ties.
- Such a modular architecture offers the ability to adapt the length of wired interconnection links. This ability to adapt is useful during assembly and repair operations as well as during architecture reconfiguration operations. For example, for the electrical infrastructures for the distribution of passenger entertainment data, present in recent aircraft (audio, video, etc.), equipment may be relocated within the aircraft cabin following a reconfiguration of the layout of the cabin (modification of the number or position of seats, etc.).
- Interconnecting wired links can thus be shortened or lengthened thanks to the possibility of storing or providing cable length additional thanks to the cable windings present in the storage housing of the equipment fixing bases.
- the mounting base When assembling an aircraft, or when reconfiguring the wired architecture, the mounting base makes it possible to temporarily make the electrical equipment independent of the wired interconnection links that concern it. Indeed, during the assembly of an aircraft, initially, all the wired interconnection links can be set up within the aircraft, as well as the fixing bases each receiving the corresponding connector. The interconnection devices are thus kept safe, although the electrical equipment boxes are not in place. Such a configuration makes it possible to proceed only in a second stage, in particular after the conformity checks, with the assembly of the electrical equipment.
- the wired interconnection links can be modified both in terms of their path and their length. Some links can be lengthened and others can be shortened without risk of damage to the cables or connectors. The electrical equipment is then refitted on the mounting bases only when the reconfiguration is complete.
- the invention also makes it possible to use, within the wired interconnection links, cables which have a predefined length which cannot be modified. For example, some cables are terminated with connectors that are difficult to install and require restrictive equipment, making it difficult and costly to cut them to the right length and install the appropriate connector on the production site. According to another example, certain cables, of sensors in particular, have a calibrated resistance and the modification of the length of the cable is not authorized. For these cables, the excess length that does not contribute to the routing of the cable may also be stored in the storage compartment of the fixing base of the equipment concerned. The level of order and secure hold of the cables will be the same as if the cable had been cut to size.
- the presence of the connector support allows the adaptation of the length of the cable without the presence of the equipment concerned, which remains protected during the operation.
- the invention is particularly advantageous for aeronautical plug-in equipment such as ARINC 836A standard formats. According to the invention, no conventional plug-in device is necessary, such as fixed chairs which require complex connections, control of the functional clearances between a box and its support, as well as complex and expensive locking systems.
- the invention indeed allows a simple fixing such as screw fixing of electrical equipment boxes.
- the invention is applicable to any type of cable (power supply, data, etc.), regardless of its technology.
- the fixing base according to the invention may comprise the following additional characteristics, alone or in combination:
- the spacer comprises a plurality of studs spaced apart from each other;
- the studs each have a lower face and an upper face, the fixing base being defined by the various lower faces of the studs, and the support face being defined by the various upper faces of the studs;
- the first side opening of the storage housing is arranged between two studs;
- the base comprises at least one protective wall extending between two studs
- the locking means of the connector support comprises an elastic tab
- the storage housing has a second side opening arranged on its edge opposite the first side opening;
- the cable ties are clip-on elements on the mounting base
- the base has a bottom wall with clipping holes for the cable ties.
- Figure 1 is a perspective view of a mounting base according to a first embodiment of the invention
- Figure 2 shows the mounting base of Figure 1 on which is mounted electrical equipment
- Figure 3 illustrates the assembly of figure 2, the electrical equipment being connected by its connector
- Figure 4 illustrates an alternative arrangement of the mounting base of Figure 1;
- Figure 5 illustrates a mounting base according to a second embodiment of the invention.
- Figure 1 illustrates a mounting base 1 for aeronautical electrical equipment according to the invention.
- the fixing base 1 comprises a spacer which is here produced by four fixing studs 2 defining a fixing base 3 and a support surface 4.
- Each of the studs 2 comprises the following attachment means:
- the upper part of the fixing studs 2, visible in figure 1, comprises in this example threaded portions 5 allowing the fixing by screws of electrical equipment placed on the support face 4.
- the fixing base 3 also comprises fixing means such as tapped or threaded portions, allowing the fixing base 1 to be fixed to a structure of the aircraft.
- the fixing base 1 further comprises a bottom wall 6 extending between the studs 2, in the same plane as the fixing base 3.
- a connector support 7 is also fixed on one of the studs 2.
- the connector support 7 is illustrated in a simplified manner in the form of a complementary housing of the connector 8 to be locked, and comprising an elastic tab 9 constituting a means of blocking of the connector 8 (the elastic tab may for example comprise a tooth for immobilizing the connector 8).
- the fixing base 1 comprises a storage housing 11 arranged between the fixing base 3 and the support face 4.
- the storage housing 11 is here of generally parallelepipedal shape and is delimited: laterally by the four studs 2, at the level higher by the plane of the support face 4; and at the lower level by the plane of the fixing base 3.
- the storage housing 11 here comprises two perforated protective walls 12 which each extend between two studs 2.
- the fixing base 1 further comprises cable ties 10 arranged in the storage housing and fixed, in the example illustrated, to the bottom wall 6.
- the cable ties 10 here each consist of an elastic clamp adapted to receive and enclose an electric cable 15.
- the mounting base 1 further comprises a side opening 13 allowing the passage of electrical cables between the storage housing 11 and the outside of the mounting base 1.
- the mounting base 1 further comprises a second lateral opening 14 located on the opposite edge of the mounting base 1.
- FIG. 1 illustrates a fixing base 1 as it appears when it is fixed to a structural element of the aircraft and when an interconnection cable 15 forming part of the network of the aircraft is installed in the fixing base 1.
- the cable 15 enters the fixing base 1 through the first lateral opening 13 and is held in position by a first cable tie 10 located at the level of this lateral opening 13 so that the cable 15 is immobilized as soon as it enters the mounting base 1 .
- the cable 15 is then coiled in the cable ties 10 distributed in the storage housing 11, that is to say that the cable 15 is arranged in windings in the storage housing 11 in favor of the ties 10. These windings are here illustrated in a simplified manner in an oval shape, but may, alternatively, have any suitable shape.
- the routing of the cable 15 causes its other end to come out of the fixing base 1 also through the first side opening 13 and the cable 15 is blocked at this level by a last cable tie 10, still at the level of the first side opening 13.
- the end of the cable 15 has a connector 8 which is put in place and locked in the support 7 of the connector.
- An aircraft or a portion of an aircraft can thus be assembled and wired with all or part of their electrical infrastructure, but without the electrical equipment in place.
- the wired interconnection links can then be checked.
- This sub-assembly can also be transported to other production sites in complete safety, both for the wiring and for the connectors.
- Figure 2 illustrates a next step in the wiring of the aircraft, during which an electrical equipment 16 is positioned on the mounting base 1.
- the electrical equipment 16 is in this example fixed by four screws (not shown) screwed into the threaded portions 5 and immobilizing four fixing lugs 17 of the equipment 16 against the studs 2.
- Figure 3 illustrates the next stage of assembly or reconfiguration in which the connector 8 is plugged into the complementary connector 18, after having been detached from the support 7 of the connector.
- the interconnection architecture is thus operational, in its final operating configuration.
- the windings of the cable 15 on the cable ties 10 are modified, by adding or removing windings, so as to reduce or increase the length of the cable 15
- the position of the fixing base 1 can thus be modified, keeping the connector 8 protected in the connector support 7.
- FIG. 4 illustrates a variant of FIG. 1 in which the cable 15 now enters the fixing base 1 through the second lateral opening 14. This is for example a case where, during initial assembly or during a reconfiguration, the routing of the cable 15 makes it more suitable for its entry into the fixing base 1 through this second lateral opening 14.
- the fixing base 1 can be provided with as many side openings as necessary, depending on the degree of adaptation desired for the fixing base 1 .
- the fixing base 1 is made in one piece: the fixing studs 2, the bottom wall 6, the connector support 7, and the protective walls 12 can be made together, for example by molding.
- the modularity of the fixing base 1 can be improved by cable ties 10 made by clipping elements in holes 19 of the bottom wall 6.
- the cable tie 10 which holds the cable 15 at the entrance to the fixing base 1 has simply been moved.
- FIG. 5 illustrates a second embodiment of the fixing base 1 which has an inexpensive structure made of simple mechanical elements. Elements similar to the first embodiment bear the same reference number to the figures.
- the fixing base 1 here comprises a storage housing 11 which is defined between four structural bars 20 which are rigidly fitted into four studs 2.
- the studs 2 have a generally cylindrical shape and each have an upper face delimiting the bearing face 4, and an underside delimiting the fixing base 3.
- the connector support (not shown) can be secured to any one of the four studs 2.
- the studs 2 comprise the threaded portion 5 on their upper part and comprise another threaded portion on their lower part for their attachment to a portion of the aircraft structure.
- the cable ties 10 are here integral with the structural bars 20 and are adapted to maintain the winding of a cable between the four structural bars 20.
- the fixing base 1 can be linked directly to the casing of the electrical equipment.
- the ties cable can then be secured to a bottom wall of the case of the electrical equipment, while fixing rails arranged on either side of these cable ties define the storage housing.
- the fixing base and the support surface are not necessarily flat and can be adapted to a box whose bottom is not flat as well as to a non-flat fixing zone on the aircraft.
