Definitions

  • the invention relates generally to a back connector. More particularly, the invention relates to a back connector capable of connecting an overshielded harness comprising shielded cables to a connector in a reliable manner and in such a way as to minimize electromagnetic disturbances. The invention also relates to a harness with terminated shielding as well as a connection comprising this rear connector.
  • electrical connections are essentially made using electrical harnesses.
  • electrical harnesses In aircraft, electrical connections are essentially made using electrical harnesses.
  • several constraints apply directly or indirectly to the electrical harnesses, in particular in the engine areas. These stresses can be of a mechanical, electrical or environmental nature.
  • EMC electromagnetic compatibility
  • the electrical connections generally have shielding which makes it possible to attenuate the disturbances received or emitted.
  • Shields can be on an individual cable (shield) and/or on the entire strand/harness (overshield).
  • the electromagnetic shielding must cover all the areas of the harness between the boxes containing the equipment. Use of these backshells, assembled to the electrical connectors, must be able to meet the electrical and mechanical requirements.
  • Requirement US-A-5052947 discloses a rear connector (shield termination) for an overshielded harness having shielded cables.
  • the rear fitting includes a sleeve and a fixing ring.
  • the overshielding of the harness is connected to a pad at the back of the sleeve and is secured to the latter by a clamping collar.
  • the cables pass inside the sleeve.
  • the ends of the cables have their conductive parts exposed.
  • the cable shield terminations pass through the through holes to the outside, and then join a land at the front of the sleeve to which they are secured by means of a cable tie.
  • the rear coupling also comprises a fixing ring mounted so as to be able to rotate at the front end of the sleeve.
  • the assembly forms a terminated shield harness for connection to a connector.
  • the object of the present invention is therefore to remedy the aforementioned needs and drawbacks by proposing a rear connector (for shielding termination) for connecting an overshielded harness comprising shielded cables to a connector, the rear connector comprising a sleeve and a ring fixing, the sleeve having a wall of substantially tubular shape defining an internal passage adapted to receive shielded cables, the wall of the sleeve comprising, from its front end towards its rear end, an engagement zone adapted to engage on a connector, circumferentially distributed through holes adapted to receive the terminations of the cable shields from the internal passage, a first external area adapted to receive the terminations of the shields, an external shoulder, and a second external area adapted to receive the overshielding of the harness , the attachment ring having a substantially tubular shaped wall defining a n annular passage adapted to receive the sleeve, the wall of the attachment ring comprising, from its front end towards its rear end, an attachment zone
  • the wall of the sleeve comprises at the front end a flared part on which the engagement zone and the through-holes are formed.
  • the through holes are located immediately behind the engagement zone, on a part of the wall up to 20% of the length of the sleeve from its front end.
  • the first outer range of the sleeve has a larger outer diameter than that of the second outer range.
  • the wall of the sleeve comprises a flared intermediate section between the first external area and the second external area.

  • the sleeve is in one piece.
  • the rear connector comprises at least one clamp adapted to secure the terminations of the shields by tightening them around the sleeve.
  • the present invention also proposes a harness with terminated shielding comprising a rear connection as described above as well as an overshielded harness comprising shielded cables, the shielded cables being received by the internal passage of the sleeve, the terminations of the shieldings of the cables passing towards the outside of the sleeve by through holes and received on the first outer region of the sleeve while the overshielding is received on the second outer region of the sleeve, and the fixing ring being mounted so as to slide above the sleeve.
  • the present invention also proposes a connection between a harness with a terminated shield as described above and a connector, the cables being electrically connected to the connector, the engagement zone of the sleeve being engaged on an engagement zone of the connector, and the fixing ring being connected to a connector attachment zone, the sleeve and the attachment ring of the rear connector being in an abutting position.
  • the figure 1 illustrates a first embodiment of the rear connector 50. It makes it possible to terminate the shielding of a harness 16, forming together with the latter "a terminated shielding harness", 70, adapted to be connected to an electrical connector 80 to achieve a connection 100.
  • the connector 80 is of a known type, often used in an aircraft.
  • FIG 2 and 3 illustrate only the main elements of the rear connector 50, namely a sleeve 20 and a fixing ring 40, in perspective and in cross-section respectively, to facilitate the understanding of the invention.
  • the rear connector 50 is connected to an overshielded harness 16 comprising shielded cables 12. It comprises a sleeve 20 and a fixing ring 40, illustrated with the fixing ring 40 slipped over the sleeve 20.
  • the sleeve 20 comprises a wall 25 of substantially tubular shape (of circular cross section) extending along a longitudinal axis, and defining an internal passage 27.
  • the wall 25 of the sleeve comprises, from its front end 21 (left side in the figures) towards its rear end 29, an engagement zone 22, circumferentially distributed through holes 24, a first outer land 26, an outer shoulder 28, an intermediate section 32, a first flange 34, a second land external 36, and a second flange 38.
  • the sleeve 20 is in one piece, and made of an electrically conductive material, typically metal.
  • the sleeve 20 is linked to a harness 16.
  • the harness 16 is of a known type and comprises individual shielded cables 12 which are grouped together in a strand, the latter being surrounded by an additional shielding 17 to protect it from EM disturbances.
  • the cables 12 and the harness 16 can also include layers of insulation in a manner known per se.
  • an 80 connector this harness must be prepared.
  • the harness 16 is stripped and unshielded towards one end, which consists in locally removing the outer insulation and the over-shielding 17 of the harness 16.
  • the shielded cables 12 of the harness 16 are stripped and unshielded at a location still closer towards the end in order to then expose the conductive part 13 of the cables 12, while keeping the terminations of the shields 14 of the unshielded cables (/pigtails) attached to the harness 16.
  • shielded cables 12 of the harness 16 are received in the internal passage 27 of the sleeve 20.
  • the conductive parts 13 of the cables 12 visible towards the end of the harness 16 are intended to be plugged into the contacts of the connector 80 to electrically connect the cables 12 to connector 80.
  • the terminations of the shields 14 are inserted through the through holes 24 to the exterior of the sleeve, and are then returned to the rear of the sleeve, and laid on the first outer pad 26 in a generally aligned manner. substantially with the longitudinal axis.
  • the first range 26 of the sleeve 20 is intended for the resumption of terminations of the shields 14. It has a generally cylindrical outer surface extending parallel to the longitudinal axis. The terminations of the shields 14 are secured there with a fastening element 33, for example a clamp 33. It is possible that axial grooves are provided to better receive the terminations of the shields 14.
  • Towards the rear of the first range 26 is the external shoulder 28, which is in the form of a ring, projecting radially from the wall 25 of the sleeve 20. This external shoulder 28 is intended to come into abutment with the fixing ring 40 to prevent it from exceeding it. , as discussed later in the description.
  • the second outer area 36 of the sleeve 20 is intended to take up the additional shielding 17 of the harness. Like the first pad, it has a generally cylindrical outer surface on which the overshield can be received. This second outer area 36 also extends parallel to the longitudinal axis, and allows the securing of the additional shielding 17 with a fastening element, for example a clamp.
  • the additional shielding 17 of the harness 16 is not received in the internal passage 27 of the sleeve 20, but directly on the second external area 36.
  • the first rim 34 located in front of the second outer range 36, is mainly designed as an abutment for the additional shielding 17, so that it does not exceed it.
  • a second flange 38 is provided behind the second range 36, and more precisely at the rear end 29 of the sleeve 20.
  • the first outer pad 26 has an outer diameter larger than that of the second outer pad 36. In this embodiment, the diameter of the first pad 26 is approximately 1.5 times that of the second pad 36.
  • the wall 25 of the sleeve comprises a flared intermediate section 32 between the first land 26 and the second land 36, increasing in diameter towards the front end 21 of the sleeve 20.
  • the wall 25 of the sleeve 20 comprises another flared part 23 at its front end 21, of increasing diameter from the first outer region 26 towards the front end 21 of the sleeve 20.
  • the engagement zone 22 as well as the through holes 24 are located on this flared part 23.
  • the through holes 24 being located on the flared portion 23 are therefore angled, facing forward and are also of a larger diameter than the first land 26. As a result, not only is it easier to handle the terminations of the shields 14 insertion into the through holes 24, moreover, they lie more naturally on the first range 26 in alignment with the longitudinal axis. This therefore allows a more uniform distribution of the terminations of the shields 14 on the sleeve 20.
  • the through holes 24 are located just behind the engagement zone 22, that is to say just behind the crown of teeth 22. This is in a region starting at the front end 21 of the sleeve 20 up to 20%, even just 10% preferably, of the length of the sleeve 20.
  • the first advantage of being located on this region is that the shields can be left on each cable 12 closer to the connector 80. In other words , only the parts of the cables 12 to be plugged into the connector 80 are unshielded, which limits the crosstalk between the conductive parts 13 of the harness 16 as much as possible, ensuring good EMC.
  • the second advantage is that the terminations of the shields 14 surround the sleeve 20 up to its connection with the connector 80, thus improving the EM protection of the cables 12 within the latter. Finally, being closer to the front end 21 of the sleeve 20 the terminations of the shields 14 are also easier to see and handle during insertion into the through holes 24, compared to the case where the holes are deeper in the muff.
  • the terminations of the shields 14 are consequently also distributed evenly around the sleeve 20.
  • the through-holes 24 are advantageously located in the same plane perpendicular to the longitudinal axis. For practical reasons of inserting the terminations of the shields 14, a small part of each of these through holes 24 can be formed in the first range 26.
  • the ring of teeth 22 is whole, that is to say that it makes a complete circle. No splits are present, and no missing teeth.
  • this crown of teeth 22 is engaged on that of the connector 80, a good connection is obtained with minimum electrical resistance and uniform electrical continuity.
  • the fixing ring 40 comprises a wall 45 of substantially tubular shape extending along the longitudinal axis, defining an annular passage 47.
  • the wall 45 of the fixing ring 40 comprising, from its front end 41 towards its rear end 49, an attachment zone 43, an internal area 46, and an internal shoulder 48.
  • the attachment ring 40 is in one piece, and made of an electrically conductive material, typically metal.
  • the fixing ring 40 is mounted around the sleeve 20, the two being oriented in the same direction with the sleeve 20 received in the annular passage 47 of the fixing ring 40. It is arranged so that it can slide above the sleeve 20, in a direction going from the rear end 29 towards the front end 21 of the sleeve, this up to an abutment position (illustrated) where the internal shoulder 48 of the fixing ring 40 abuts with the outer shoulder 28 of the sleeve 20.
  • the inner shoulder 48 is in the form of a ring, projecting radially from the wall 45 of the fixing ring 40.
  • the fixing ring 40 is illustrated in front of a connector 80 for its connection to it.
  • the internal area 46 of the fixing ring 40 covers the first external area 26 of the sleeve 20. Consequently, the terminations of the shields 14 are entirely covered by the fixing ring 40, this which provides protection against EM disturbances. Unlike the prior art, EMI cannot enter through openings or through holes in the sleeve.
  • the assembly comprising the internal range 46, the internal shoulder 48 and the fixing zone 43 of the fixing ring 40 surrounds the terminations of the shields 14, and beyond the front end 21 of the sleeve 20.
  • the rear connector 50 is arranged in such a way that a Once connected to the connector 80, the fixing ring completely surrounds the terminations of the shields 14, the engagement zone 22 of the sleeve 20 and the engagement zone 82 of the connector 80 as well as its fixing zone 83.
  • the securing ring 40 can slide relative to the sleeve 20 allows it to be removed when the terminations of the shields 14 are inserted into the through holes 24 and then replaced.
  • O-rings 44 are advantageously used. They are provided just next to the internal shoulder 48, and in front of the internal area 46 of the fixing ring 40. If necessary, circumferential internal grooves can be provided to accommodate the O-rings 44. These O-rings 44 are arranged to be interposed between the fixing ring 40 and the sleeve 20, and between the fixing ring 40 and the connector 80. In addition, a protective sheath (boot) 54 can cover the sleeve 20 from its first edge 34, beyond its rear end 29 as far as part of the harness 16. The assembly comprising the O-rings 44 and the protective sheath 54 make it possible to seal the connection.
  • the rear connector 50 of the invention is more efficient than the known rear connectors, above all by making it possible above all to make a reliable connection 100 between an overshielded harness 16 comprising shielded cables and a connector 80.
  • the terminations of the shields 14 of the cables 12 are distributed uniformly around the sleeve 20 and arrive very close to the front end 21 of the sleeve 20. What is more, they are completely covered by the fixing ring 40 when it is in the abutment position.
  • the rear connector 50 is made of two main elements which are each in one piece. Additionally, sleeve 20 includes an entire crown of teeth 22.
  • the overshielding 17 and shielding terminations 14 on the sleeve 20 prevent the forces from being applied directly to the conductive parts 13 plugged into the connector 80.
  • the distribution as well as the positioning of the shielding terminations 14 on the rear connector 50 provide better continuity electrical power and reduced transfer impedance. Having only two main elements, the rear connector 50 is easier to install on a harness 16, and less likely to be lost.
  • the connection of the overshielding 17 and the shieldings 14 (to the connector) is ensured by a single conductive part, having a much better electrical continuity than a sleeve in several parts. As a result, the rear connector 50 is more efficient in terms of EMC.
  • the invention has been described in relation to an overshielded harness comprising shielded cables. However, it is also suitable for other cables, for example an unshielded harness with shielded cables, or even a single shielded cable.
  • the invention can be used at the same time as other known means of protection against EM disturbances.
  • the rear connector of the invention can be retrofitted (or “retrofitted") to the connections already existing in the aircraft.
  • the intermediate section may be a flange perpendicular to the axis and incorporate, where appropriate, the outer shoulder of the sleeve.
