Definitions

  • the present invention relates to shielded links serving different connection points. It relates more particularly to the mounting of a connector on a terminal part of a shielded link used under conditions of strong electromagnetic illuminations.
  • Such a shielded connection is of defined configuration and comprises, according to this configuration, a linear cord of conductors or a bundle consisting of multiple branches of conductors and its terminal connectors for connection to the various connection points.
  • the shielding against the electromagnetic disturbances of a linear cord and in particular of the linear parts of a bundle formed can be produced by metallic braiding shields.
  • the rear part for connecting the connectors to the cord or harness must itself be protected by a shield. This protection can be obtained by grinding, to put it on the rear part of the connector, the end of the braid shielding the cord or the branch of the bundle formed.
  • the low performances obtained by threading the shielding braid on the rear part of the connector can be improved, by fitting a heat-shrinkable sheath on the rear part of the connector and the end of the braid.
  • This heat-shrinkable sheath must provide a seal over the shielding braid, but in practice it turns out that a sufficiently retractable and perfectly waterproof sheath is uncommon for a significant difference between the diameters of the connector and of the cord or branch to which the connector is connected.
  • the installation of this sheath is not always easy, especially when the connector is connected, given that it is ensured after the connection has been installed.
  • the object of the present invention is to connect a connector to one end of an already shielded link, avoiding the aforementioned drawbacks and in particular allowing easy and rapid mounting of the connector, with high electromagnetic protection at its level and without degrading the shielding of the terminal part of the link connected to this connector.
  • the invention relates to a shielded link and pre-equipped for mounting a connector on an end part of said link, with a conductor strand and shielding braid covering said strand, characterized in that it comprises an enlarger, of transverse dimensions. substantially identical to those of a so-called rear end of the connection of said connector, positioned on said end portion substantially at the connection location of said connector and at least partially covered by said shielding braid preformed on the expander with transverse dimensions of this one.
  • FIG. 1 only one of the terminal parts of a shielded link 1 has been illustrated, which is pre-equipped for mounting a connector 2 (FIG. 2) on this terminal part.
  • This terminal part is designated below by the reference 1 of the link to which it belongs.
  • Such a shielded connection has a preset configuration. It is constituted for example by a linear cord or by a bundle made up of conductors, this bundled made up having multiple branches and having one or more branches. It is connected to two terminal connectors on the cord or to as many connectors as multiple terminal branches of the bundle formed, to serve corresponding connection points.
  • the shielded connection is made of stranded conductors of which all or part of them belongs to the terminal part 1.
  • the conductors of this terminal part are designated under the reference 3.
  • This link is shielded over its entire length. This shielding is ensured, at least as regards the linear portions of the connection and therefore the terminal portion concerned 1, by a shielding braid, single or multi-layer, 4.
  • this terminal part 1 is equipped with an expander 5 mounted directly on its conductor strand, before its shielding.
  • the expander is positioned at the location where the aforementioned connector will be connected.
  • the shielding braid 4 is then executed, with the expander in place on the conductor strand, during the same braiding operations.
  • a positioner 6 is held substantially at the end of the strand of conductors 3. It serves as a front stop for the expander, then correctly positioned, and prevents it from being moved before and unexpectedly removed during the braiding operations or subsequently from below. of the shielding braid.
  • This expander has identical transverse dimensions, as rigorously as possible, to those of the rear end of the connector.
  • the so-called rear end 5A of the expander, the innermost on the terminal part 1, is profiled by having a rounded or conical shape. It allows an easy and smooth transition of the shielding braid between the expander and the conductor strand, of different transverse dimensions.
  • the expander is made of hard material, which can be metal or plastic.
  • the shielding braid 4 produced in one or more layers overlapping one another, is executed continuously along the length of the terminal part already carrying the expander. It is thus preformed to the transverse dimensions of the expander and thereby to those of the rear end of the connector.
  • the braiding can be carried out with different braiding steps on the expander and on the conductor strand, with a continuous variation at the transition, to allow if necessary and in particular when there is a significant difference in transverse dimensions between them, obtaining high performance protection over the entire length of the terminal part 1, including included on the expander.
  • the shielding braid 4 completely covers the expander, or may cover it only partially. Being preformed to the transverse dimension of the rear end of the connector, it avoids any crushing liable to degrade its characteristics when the connector is installed.
  • the expander 5 also serves as a bearing surface for cutting to the correct length of the shielding braid 4. It also protects the conductors it covers from injuries that this cutting could cause.
  • the section plane of the shielding braid is identified at 7, at a distance from the rear end of the expander substantially equal to the length of the rear connection end of the connector. This cut eliminates the excess braid length and removes the expander to slide the rear end of the connector under the shielding braid without deforming it.
  • fixing accessories such as 'a fixing ring 8 shown in dotted lines, when these accessories are of closed structure.
  • These accessories are deformable or retractable, for subsequent tightening of the shielding braid on the rear end of the connector, either by crimping or cryogenics or magnetostriction, in particular, depending on the nature of their materials.
  • different means can be used for fixing the shielding braid to the rear end of the connector.
  • a metallic and flexible protective strip 9, closed on itself, can also be associated with the fixing accessories, as shown in dotted lines.
  • FIG. 2 shows this terminal part 1 connected to its connector 2.
  • This connector has a body in two parts, one at the rear 11 and the other at the front 12 which are assembled to each other by a connecting nut 13 .
  • the rear part defines an expansion and distribution chamber for the conductors of the strand 3, the excess length of the conductors possibly being cut off. It is at the rear end which forms a rear collar 14 for entry of the conductors into the chamber and is threaded under the shielding braid, the latter being fixed by means such as 8, possibly with the intermediate protection 9.
  • the front part 12 comprises a plurality of contacts 15 mounted and retained in an insulating block 16, to which the conductors of the strand are connected.
  • the contacts are also protruding on the insulating block in the front face of the connector.
  • a front peripheral nut 17 on this connector ensures its locking on a complementary connector at the connection point of this terminal part.
  • the elements identical to those of FIG. 1 are designated by the same references.
  • the shielding braid is designated by the reference 4 ′ to translate its differences, specified below, with respect to the shielding braid in FIG. 1.
  • This shielding braid 4 ′ further comprises a self-locking loop 24 produced with the execution of the braid.
  • This loop is almost adjacent to the rear end 5A of the expander and extends over the conductor strand 3, over a few centimeters. It is obtained by a back and forth movement of the braiding, during the execution of the different layers or at least of the single final layer, when the shielding braid is multilayer, so as to form a double hem.
  • This loop prevents any slipping of the possible multiple layers of the shielding braid, one on top of the other, in particular when cutting excess length of the braid and the fitting and connecting the connector. It directly acts as a ring for fixing the shielding braid to the conductor strand.
