Definitions

  • the present invention relates to a shielded electrical harness comprising a bent connector, and to a method of manufacturing such a harness.
  • the technical field of the invention is that of the manufacture of electrical harnesses intended to equip a rotorcraft.
  • the patent US 1565321 discloses a flexible electrical cord having a fabric sheath and a flexible rubber over-molded protective sleeve.
  • the patent US 4006956 discloses a grommet device for connecting a plug or microphone to a multi-conductor cable; the device comprises a disk pierced with an opening through which the cable extends, a heat-shrinkable sleeve surrounding the disk and a portion of the cable and extending through an opening of the plug housing; the length of the conductors is such that they are not fully extended, so that pulling on the cable causes stress in the plug housing rather than in the conductor connections to the plug.
  • connection device between a cable and a connector which comprises a flexible tubular body made of non-metallic braided filaments; this body is fixed to the cable by an adhesive heat-shrinkable sleeve, as well as to the connector, to limit the stresses in the connection.
  • the patent EP-1 191 639 describes an angled connector equipping a bundle of optical or electrical cables.
  • US 3546658 describes a beam according to the preamble of claim 1.
  • the invention applies to this type of beam, at least the branch equipped with the connector is protected by a shielding sheath or braid, which is generally metallic and slightly deformable, and which is secured to a second end of the envelope or duct bent (e).
  • the base is intended to be plugged into a corresponding part of a (second) connector complementary to a second beam -or equipment- to ensure electrical continuity between the pins of the two connectors.
  • the two connectors must be aligned, and must therefore extend in a determined mutual orientation.
  • the racking connectors requires that the orientation of the bent connector of the beam corresponds to that of the second connector; the rigidity of the shielded beam may hinder or prevent the orientation of the angled connector that it comprises; in some cases it is possible to loosen the fixing member of the casing and the base, change the mutual orientation of the casing and the base, then tighten the fastener; however, the magnitude of this orientation change is limited; such a modification may also subject one or more conductors to unacceptable mechanical stresses.
  • the invention particularly aims to provide a shielded electrical harness equipped with a bent connector and a method for its manufacture, which are improved and / or which remedy, at least in part, the shortcomings or disadvantages of known harnesses.
  • a harness or beam which comprises one or more integral stop member (s) of the portion of the wire sections extending inside the envelope or duct. bent (e), (s) stop member (s) cooperating with the bent envelope to prevent this portion of the wire sections out of this envelope.
  • this portion of the wire sections is twisted or twisted so that the mutual orientation of the base and the casing can be modified without introducing damaging mechanical stresses in these portions of wire sections.
  • FIGS. 1 to 6 illustrate successive steps of a method according to the invention for manufacturing a harness, and are schematic partial sectional views of an end of a branch of a harness to be fitted with a bent connector, in a plane containing the longitudinal axis (reference 32) of the wires of this branch.
  • the figure 7 illustrates a harness according to the invention obtained by this method.
  • the harness 10 shown figure 7 has a single branch equipped at each of its two ends, an angled connector 11,12 and coated with a shield 40.
  • Connector 11 Figures 5 to 7 comprises an angled envelope 13, a base 14, and a ring 15 for removably securing the envelope 13 to the base 14.
  • the ring 15 has on its internal face a female thread 16, designed to cooperate with a male thread of shape and complementary dimension, which is provided on the outer face 17 of the base 14; this last thread is not shown so as not to impair the clarity of the figures; thus, this securing is obtained by engaging the threaded parts one in the other, and causing a mutual rotation of the two parts 14 and 15 along an axis 18 corresponding substantially to an axis of approximate symmetry of these two parts.
  • a bearing surface 19 (in the form of an annular flange) of the ring 15 bears on a complementary bearing surface 20 (also in the form of an annular flange) of the bent envelope 13, until it reaches the clamping of the piece 13 - by its flange 20 - against the base 14.
  • the base 14 is pierced with three channels 21 ( Figures 5 and 6 ) respectively intended to receive the ends of three conductors 22 to 24 of the harness; these ends are integral - by crimping or welding for example - pins (male or female) engaged in these channels 21.
  • the envelope 13 delimits a bent cavity 25 which opens on the one hand by a first opening 26 provided in a wall 27 located at a first end 28 of the envelope 13, and on the other hand by a second opening 29, provided in a wall 30 at a second end 31 of the casing 13.
  • the second end 31 is in the form of a cylindrical sleeve extending along an axis 32, and the first end is also of cylindrical shape with an axis 18, and is terminated by the collar 20, the axes 18 and 32 being, usually coplanar without being parallel (or confused).
  • the mutual orientation of the base 14 and the bent body 13 can be changed at any time, plus or minus 90 to 180 °.
  • the conductors are substantially immobilized with respect to the end 31 of the body 13 by the sleeve 33 resting on the flat abutment 36.
