DETAILED DESCRIPTION

[0076] Elements that are present in more than one of the figures are given the same references in each of them.

[0077] FIG. 1 shows an example of a protective assembly 1 according to the disclosure. This assembly 20 may be arranged in a connection system 10, and indeed within a vehicle 1. Such a vehicle 1 may be an aircraft, a land or sea vehicle, etc. Such an assembly 20 may more generally be used in various systems provided with a connection system 10.

[0078] Irrespective of the embodiment, a connection system 10 comprises a first connector 11 connected to a first link 12. The first link 12 may lead to a member 2. The first connector 11 may, for example, include at least one electrical conductor electrically connected to an electrical conductor of the first link 12 in order to convey electrical power or data, at least one light conductor connected to an optical fiber of the first link 12, at least one port through which an optical fiber of the first link 12 passes, or indeed at least one duct connected to a pipe of the first link 12 in order to convey a fluid.

[0079] The connection system 10 also comprises a second connector 13.

[0080] The second connector 13 may simply be configured to be fastened to the first connector 11. In this case, the second connector 13 may be a holder base 4 and may not communicate fluidically, optically or electrically with the first connector 11.

[0081] Alternatively, the second connector 13 may be connected to a second link 14. The second link 14 may lead to another connector connected to a member 3. The second connector 13 may, for example, include at least one electrical conductor electrically connected to an electrical conductor of the second link 14 and to an electrical conductor of the first connector 11 in a connected mode MODC in order to convey electrical power or data, at least one light conductor connected to an optical fiber of the second link 14 and to a light conductor of the first connector 11 in a connected mode MODC, at least one port through which an optical fiber of the second link 14 passes, at least one duct connected to a pipe of the first link 12 and to a duct of the first connector 11 in a connected mode MODC in order to convey a fluid.

[0082] For example, FIG. 1 shows electrical connectors whereas FIG. 9 shows fluid or optical connectors.

[0083] Moreover, the first connector 11 may be a female connector and the second connector 13 may be a male connector configured to penetrate into the female connector, or vice versa.

[0084] Irrespective of the nature of the first connector 11 and the second connector 13, the first connector 11 and the second connector 13 may comprise a locking system 15.

[0085] According to the example shown in FIG. 1, a locking system 15 may comprise a pin 16 of one connector and a bushing of the other connector provided with an L-shaped groove 17. The pin 16 and the bushing are able to rotate relative to each other. The pin 16 is pushed into one leg of the groove 17 and then rotated in order to immobilize the pin 16 in the other leg of the groove 17. The connector provided with the bushing is, for example, a male connector, and the connector provided with the pin 16 is a female connector.

[0086] According to the example shown in FIG. 9, the locking system 15 may comprise a threaded bushing 18 of one connector, the threaded bushing 18 being capable of being screwed to a tapping of the other connector. The connector provided with the bushing is a male connector, the other connector being a female connector.

[0087] These examples are given by way of illustration.

[0088] Irrespective of the nature of the first connector 11 and the second connector 13 and a locking system 15 that may be provided, the figures show various variants of a protective assembly 20 according to the disclosure.

[0089] Regardless of the variant and with reference to FIG. 1, a protective assembly 20 according to the disclosure comprises a hollow first cap 30 delimiting a first cavity 31 configured to house a first connector 11.

[0090] For example, the first cap 30 comprises a hollow part 32 that extends from a first proximal end 33 to a first distal end 34. The first proximal end 33 is open onto an external environment EXT while the first distal end 34 is closed by a first bottom 35. Consequently, the first cavity 31 is blind in the sense that it opens onto the external environment EXT only at the first proximal end 33. The hollow part 32 includes an inner wall 320 locally delimiting the first cavity 31. For example, the inner wall 320 is substantially cylindrical in shape and has a first radius R1.

[0091] Furthermore, the first cap 30 may be secured to a first fastener 37. The first fastener 37 extends from a first zone 371 to a second zone 372. The first zone 371 is fastened by conventional methods to the first cap 30, and, for example, to the first bottom 35. The second zone 372 is attached to the first connector 11 or to the first link 12. For example, the second zone 372 comprises a ring arranged around the first connector 11 or the first link 12.

[0092] The first cap 30 is optionally made from a shape memory material.

[0093] The first cap 30 and the first fastener 37 optionally form a one-piece component.

[0094] Therefore, and with reference to FIGS. 2 and 3, in a disconnected mode MODNC, the hollow part 32 can be fitted over the first connector 11 in order to protect it from particles present in the external environment EXT. Then, when the first connector 11 is not in operation, the first cap 30 prevents foreign particles such as pebbles, dust particles, water or the like from penetrating into the elements of the first connector 11 capable of conveying an electric current, a fluid or light.

[0095] With reference to FIG. 1, the protective assembly 20 comprises a hollow second cap 40 delimiting a second cavity 41 configured to house the second connector 13.

[0096] For example, the second cap 40 comprises a hollow portion 42 that extends from a second proximal end 43 to a second distal end 44. The second proximal end 43 is open onto the external environment EXT while the second distal end 44 is closed by a second bottom 45. Consequently, the second cavity 41 is blind in the sense that it opens onto the external environment EXT only at the second proximal end 43. For example, the hollow portion 42 comprises an inner casing delimiting the second cavity 41 and an outer casing 420 facing the external environment EXT in the disconnected mode. For example, the outer casing 420 is substantially cylindrical in shape and has a second radius R2. The second radius R2 is optionally substantially equal to the first radius R1.

[0097] Furthermore, the second cap 40 may be secured to a second fastener 47. The second fastener 47 extends from a first section 471 to a second section 472. The first section 471 is fastened by conventional methods to the second cap 40, and, for example, to the second bottom 45. The second section 472 is attached to the second connector 13 or to the second link 14. For example, the second section 472 comprises a ring arranged around the second connector 13 or the second link 14.

[0098] The second cap 40 is optionally made from a shape memory material.

[0099] The second cap 40 and the second fastener 47 optionally form a one-piece component.

[0100] As shown in FIG. 4, the second cap 40 may include a positioning mark 48 outside the second cavity 41. For example, the outer casing 420 of the portion 42 comprises this positioning mark.

[0101] Therefore, and with reference to FIGS. 4 and 5, in the disconnected mode MODNC, the hollow portion 42 can be fitted over the second connector 13 in order to protect it from particles present in the external environment EXT.

[0102] Then, when the second connector 13 is not in operation, the second cap 40 prevents foreign particles such as pebbles, dust particles, water or the like, if present, from penetrating into the elements of the second connector 13 capable of conveying an electric current, a fluid or light.

[0103] With reference to FIG. 1, the shape of the outer casing 420 of the hollow portion of the second cap matches the shape of the first cavity 31 and the inner wall 320 of the hollow part 32.

[0104] In the connected mode MODC shown in FIG. 1, the first connector 11 is linked/connected to the second connector 13. Moreover, the second cap 40, and in particular its hollow portion 42, penetrates into the first cavity 31 in sealed manner. The second cap 40 is nested in the first cap 30, head to tail.

[0105] More precisely, the outer casing 420 of the hollow portion 42 is inserted by its second proximal end 43 into the hollow part 32.

[0106] Consequently, the second cap 40 is arranged in the first cap 30 with a tight fit so as to prevent foreign particles from entering the first cap 30 and the second cap 40.

[0107] Optionally, the inner wall 320 of the hollow part 32 includes a seal and/or the outer casing 420 of the hollow portion 42 includes a seal in order to promote tight sealing between the first cap 30 and the second cap 40 in the connected mode.

[0108] If applicable, the second cap 40 is inserted into the first cap 30 until the positioning mark 48 is no longer visible.

[0109] With reference to FIG. 6, the first cap 30 may have a first shape 36 on its inner wall 320 facing into the first cavity 31. Similarly, the hollow portion 42 may comprise a second shape 46 on its outer casing 420 outside the second cavity 41. The second shape 46 may match the first shape 36 in order to hold the second cap 40 in the first cap 30 in the connected mode MODC. According to the example shown, the first shape 36 comprises an annular groove and the second shape 46 comprises a matching annular protuberance. The first shape 36 and the second shape 46 can therefore cooperate with each other and form reversible snap-fit fastening means. The reverse is also possible.

[0110] FIGS. 1 to 6 show an example of an assembly that can be adapted to an electrical connection system, for example.

[0111] FIGS. 7 and 8 show an assembly that can be adapted to a system having a first connector 11 of the cylindrical female electrical socket type and a second connector 13 of the flat male electrical plug type. The second cavity 41 is then adapted to the shape of this second connector 13.

[0112] FIG. 9 shows a fluid or optical connection system, for example.

[0113] The assembly according to the disclosure can therefore be adapted to various types of connectors.

[0114] Naturally, the present disclosure is subject to numerous variations as regards its implementation. Although several embodiments are described above, it should readily be understood that it is not conceivable to identify exhaustively all the possible embodiments. It is naturally possible to envisage replacing any of the means described by equivalent means without going beyond the ambit of the present disclosure.
