Definitions

  • the invention relates to a connection device for connecting an auxiliary interface for a fast bus (USB3.0, Eth10Gb, DVI, etc.) of an equipment subject to demanding robustness standards (of the aeronautical or military type) directly to a device. consumer terminal of the laptop or tablet type.
  • a fast bus USB3.0, Eth10Gb, DVI, etc.
  • On-board equipment typically includes an electrical interface for a fast bus (USB3.0, Eth10Gb, DVI, ...) in order to allow a user to load or unload large volumes of data from a computer or uncured peripheral equipped a cable terminated by a commercial standard plug.
  • a fast bus USB3.0, Eth10Gb, DVI,
  • the on-board equipment must be certified for aeronautics or the military and its connector base must be robust (mechanical robustness and electromagnetic robustness) and waterproof (humidity).
  • MIL-DTL-38999 Military and aeronautical range connection devices are known (MIL-DTL-38999 for example) which allow high bandwidth signals to be transmitted on “quadrax” or coaxial contacts while maintaining signal integrity and compatibility with the constraints of on-board equipment.
  • connection device 100 with its Ethernet cord 200 to be connected to a commercial PC.
  • Watertight bases are also known which make it possible to deport the base to the commercial standard through a partition, but in this case, the internal connection to the equipment incorporates a plug and a cord that do not comply with certification requirements.
  • the figure 2 illustrates such a device 100 ′ for connection with the internal cord 300 (here a USB cord).
  • connection device comprising: a qualified base body according to a first standard meeting the requirements for withstanding severe environments, the base body being hollow and intended to be fixed to a panel of on-board equipment; an external connector permanently housed in the base body, the external connector being defined according to a second standard different from the first standard, said external connector not being qualified to meet the requirements of the first standard; an internal connector connected to the external connector, said internal connector being adapted to be connected to a card of the on-board equipment; a flexible transition housed at least partially in the base body and disposed between the external connector and the internal connector.
  • An object of the invention is to have a connection device whose external electrical interface is adapted to the commercial standard in force for computer equipment (USB, eSATA, DVI, HDMI, Ethernet, etc.) inserted into a socket. certified to an aeronautical, military or equivalent standard.
  • the invention allows the internal transition which connects this connection device to the electronic circuit to be both robust and adapted in impedance over a large bandwidth.
  • a terminal 1 of the commercial laptop type (a terminal can also be a tablet, a smartphone or any other terminal adapted to be connected to a peripheral) which can be connected to an equipment 2 of the on-board type via a commercial cord 3 .
  • a cord 3 includes a plug to the consumer standard in force (on the figure 1 a USB standard plug).
  • the cord 3 is connected to the equipment 2 via an external connector accessible from the front face of a panel of the equipment 2 using a device 20 illustrated in the figures 2 to 16 .
  • the connection device 20 comprises a base body 21 qualified according to a first standard.
  • a first standard is for example the standard MIL-DTL-38999, the standard MIL-DTL-22992, the standard MIL-DTL-26482 or more generally any standard qualified for severe environments (in aeronautics, defense or in the field space in particular).
  • the figure 22 illustrates a connector defined according to the first standard and which conventionally comprises the cylindrical base body 21 housing contacts 210 ′ thus forming a so-called complete connector.
  • the base body 21 is particularly qualified in that it is configured to be robust and waterproof, withstand the severe environments provided for by its standard.
  • An assembly 210 comprising an external connector 22 defined according to a second commercial standard, potentially intended for general public use in a domestic environment, is housed inside the base body 21 and maintained by a mechanical interface described below, not defined by standards.
  • the external connector 22 is not qualified.
  • a base body without its contacts that is to say hollow and empty
  • a commercial connector 22 also comprising a base body and contacts.
  • the contacts 210 ′ leave room for the assembly 210 comprising the external connector 22.
  • An internal connector 23 is connected to the external connector 22.
  • the external connector 22 is of the USB type.
  • Internal connector 23 connects to a card of equipment 2.
  • the figures 17 to 21 illustrate the internal connector 23 connected to a card 29 of equipment 2.
  • the device 20 comprises a transition 24, 25, 25 'adapted in impedance between the external connector 22 and the internal connector 23 configured to, in operation, adapt the impedance of the lines passing between the internal connector 23 and the connector 22 external.
  • the adapted transition 24, 25, 25 ' is preferably housed at least partially in the base body.
  • the adapted transition 24, 25, 25 ' comprises a flexible circuit 24 connecting by controlled impedance lines a first printed circuit 25 supporting the external connector 22 and a second printed circuit 25' supporting the internal connector 23. It is the placing in series of these elements (flexible circuit, printed circuits) which ensures the continuity of the transmission of the signal in the connection device while respecting the line impedance all along the path of the latter.
  • Printed circuits 25-25 ' can be etched with ground planes providing shielding for electromagnetic compatibility. Likewise, on these circuits, imprints performing the impedance adaptation of the transition between their connector and the flexible circuit and / or filtering functions can be etched.
  • the internal connector 23 is soldered onto the second printed circuit 25 ′ which makes it possible to select it of a smaller size than the external connector 22 in the general public format. Indeed, the use of a printed circuit makes it possible to have a very low resolution between two adjacent contacts (of the order of 250 ⁇ m).
  • the connector 23 can be connected to the card 29 of the equipment in a robust manner by screws 291 which make it possible to fix the connector 23 to the card while ensuring a mechanical hold that meets the constraints of the on-board vehicle.

  • the first printed circuit 25 is fixed on a support plate 26.
  • the shape and dimensions of the support plate 26 are such that the latter is fixed to the base body 21, in particular to its fixing plate 211 by means of the screws 28 (four here). These screws 28 also make it possible to fix the connection device on the front face of the equipment 2.
  • the base body 21 consists of this fixing plate 211 from which extends a tube 212. It is inside the tube 212 that the external connector 22 is housed, held by the integral assembly. consisting of the printed circuit 25 and the support plate 26.
  • the specific shape of the support plate 26 and printed circuit 25 assembly makes it possible to position the end of the external connector 22 in the center and flush with the opening of the tube 211, constituting thus a mechanical adaptation between two different standards which is not defined by either of the two standards.
  • a cylinder 27 can also wrap the external connector 22 to hold it rigidly and protect it so as to make the assembly very robust. This will preferably be made of an insulating material.
  • this cylinder 27 is made in two parts 271, 272 so as to firmly hold the external connector 22 when these two parts 271, 272 are attached together by means of screws 273.
  • the external connector 22 is embedded in a material which solidifies when cold such as an insulating and resistant resin, this material then constituting the cylinder 27 in a single block which coats the external connector 22.
  • the latter is fixed to the support plate 26 by means, for example, of a retaining tab 29 which is screwed to the support plate 26 by means of screws 291 (here two screws 291) .
  • the latter comprises a captive plug (not shown) which screws onto the external part of the tube 212 of the base body 21 which is as such threaded.
  • the plug which is part of the first robust standard to which the base body 21 meets, makes it possible to protect the external connector 22 when not in use. Such a plug is removed when a user wishes to connect an appliance to the external connector 22 which is then accessible.
