Definitions

  • the invention relates to a shield connection device between a protective and shielding box for a high-voltage device and a cable shielded comprising at least two conductors and a shielding braid tubular surrounding said conductors.
  • the object of the invention is to ensure continuity shielding between the protective and shielding box of a high-voltage device such as a discharge lamp and the housing protection and shielding of a high voltage generator.
  • Discharge lamps need a high voltage supply of the order of 20 to 25 kV to ensure their operation, especially during of their re-ignition. Without specific protection, the cable supplying these discharge lamps generate electromagnetic interference which can disrupt the electronic equipment of an automobile, such as radio, air conditioning, on-board computer, ... We understand that, to use discharge lamps in an automobile, it is necessary to carry out a protection electromagnetic high voltage power cable from the lamp to dump.
  • the purpose of the shield connection according to the invention is to ensure the shielding continuity between a shielded cable and each of the protection and shielding that surrounds an electrical device to which are connected the conductors contained in the shielded cable, in order to prevent the emission of electromagnetic interference by the shielded cable.
  • Shielding efficiency can be measured using the impedance of transfer of the assembly constituted by the shielding and the housing.
  • the impedance of transfer defines in a given frequency the contact resistance between the shielding and housing for this frequency range.
  • the techniques of 360 ° electrical continuity offer the better transfer impedance.
  • the receptacle comprising all the elements forming a headlamp, such as a headlamp for a vehicle automobile, is of very limited size, so that the connection of shielding between the protective housing and shielding of the discharge lamp and the protection and shielding box of the high voltage generator must be able to enter a very limited space. So, we understand that it is desirable that the shield connection device has a small footprint, can be easily disassembled and makes a connection shielding as efficient as possible.
  • an object of the invention is to provide a shielding connection device which has the aforementioned advantages and which ensures optimum shielding continuity despite a succession of assembly and disassembly of the shielding connection device.
  • the electrical continuity of the braid constituting the cable shield is provided by the ferrule.
  • This is profiled to receive the braid on its first end, the contact being achieved through the clamping ring.
  • the second end of the ferrule is profiled to be in contact with the protective and shielding box of the high-voltage device on a 360 ° angle, thanks to the cooperation between the elastic retaining ring and the annular rib of revolution of the ferrule.
  • This 360 ° contact allows, in addition to an impedance of satisfactory transfer, removable rotary contact.
  • FIG. 2 We will refer to Figure 2 to better visualize how the shield connection is made between the braid 26 and the protective box and shielding 12, by means of a shielding connection device 10.
  • the ferrule 30 serves as an intermediate piece allowing, thanks to a suitable form, to carry out the shielding continuity between the braid 26 and the housing 12.
  • the annular clamping ring 46 which is shaped to allow this support contact of the braid on substantially the entire periphery of the first end 34 of the ferrule 30.
  • Such a clamping ring 46 may be similar to the collar of connection described in French patent 2,671,435 of the applicant.
  • the continuity of the shielding also takes place at the level of the second end 36 of the ferrule 30 which is shaped to allow a 360 ° contact with the wall of the housing 12.
  • the second end 36 of the ferrule of revolution 30 has an annular rib of revolution 38 comprising a shoulder 40 turned towards the edge free from the second end 36 of the ferrule 30.
  • This shoulder 40 has an annular contact surface 42, planar and orthogonal to the axis of revolution of the ferrule 30.
  • this contact surface 42 can come to bear against the annular zone 44 of the outer surface of the housing 12 which surrounds the opening 28, it is expected that the annular rib 38 has a diameter outside greater than the diameter of the opening 28.
  • the cylindrical surface of annular revolution 43 which is longitudinal and contiguous to the radial contact surface 42 at the level of the shoulder 40 enters the opening 28 of the housing 12 and therefore has a diameter at more equal to the diameter of the opening 28.
  • an elastic retaining ring 54 is mounted so removable on the second end 36 of the ferrule 30, this ring of elastic support 54 being shaped so that its outer contour 60 is based on the internal face of the housing 12 and so that its internal contour 58 either retained against stop means integral with the second end 36 of ferrule 30.
  • these abutment means consist of a abutment rib 62 annular, of revolution and adjacent to the free edge of the second end 36 of the ferrule 30.
  • the shielded cable 20 is located the inside of a protective sheath 64, preferably flexible, surrounding the braid 26 at least up to the clamping ring 46.
  • This protective sheath 64 is preferably made of a flexible material such as the elastomer and is intended to mechanically protect the braid 26 so to avoid any alteration of the shielding continuity provided between the two boxes 12 and 16 by this braid 26.
  • FIG. 3 illustrates a ferrule 30 which is metallic and is made for example in a Cu-Zn alloy which can be coated with a metallic layer minimizing the electrical resistance of contact with the housing 12 or 16, preferably a layer of nickel of a thickness between 2 and 5 ⁇ m.
  • this has a length of 9.6 mm
  • its first end cylindrical 34 has a diameter of 9.8 mm
  • a bead 66 is arranged over the entire periphery of the first end 34 at the free edge to prevent sliding of the clamping ring and the separation between the first end 50 of the braid 26 and the ferrule 30.
  • the internal diameter of the ferrule is for example of the order of 8.2 mm.
  • the rib annular of revolution 38 having a crenellated profile and the shoulder 40 delimiting the side of the annular rib of revolution 38 facing the free edge of the second end 36 of the ferrule 30.
  • This shoulder 40 has the contact surface 42 and the cylindrical surface of revolution 43.
  • the diameter of the surface 43 is equal to the diameter of the circular opening 28 of the housing 12, for example of the order of 10 mm.
  • the free edge of the second end 36 of the ferrule 30 has a second annular rib of revolution 62 having a section cross-shaped niche.
  • the outside diameter of the second rib 62 is equal to the outside diameter of the surface 43 (10 mm) so that there is a shoulder 72 between the surface 68 and the surface 43.
  • the change in diameter at the shoulders 70 and 72 that is to say the difference in diameter between the surfaces 43 and 68, is by example of the order of 1 mm.
  • the distance separating the annular rib 38 abutment means constituted by the rib 62 is substantially equal to the sum of the thickness of the wall of the annular zone 44 of the protective and shielding casing 12 around the opening 28 and the distance separating the planes including the interior contour respectively 58 and the outer contour 60 of the retaining ring 54.
  • the wall of the housing 12 has a thickness of 0.3 mm equal to the thickness of the ring formed by the surface 43 and the width of the peripheral surface 68 is equal to the distance separating the plans comprising respectively the inner contour 58 and the contour outside 60 of the retaining ring 54, for example 1.3 mm.
  • FIGS. 4, 5A and 5B we will now refer to FIGS. 4, 5A and 5B in order to illustrate the forms elastic retaining rings 54 and 56.
  • the elastic retaining ring 54 In front view (FIG. 4), the elastic retaining ring 54 is not closed but extends over an angle at the center of at least 200 °, preferably at least 270 ° and again more preferable between 290 and 320 °.
  • the outer contour has an arc shape.
  • the inner contour comprises three sections of circular arc 74 between which are formed recesses 76.
  • the interior contour 58 is strictly in the shape of a circular arc provided that the material in which is made the elastic retaining ring 54 is sufficiently flexible.
  • This elastic retaining ring 54 can be made of plastic, metal or any other material sufficiently elastic to allow to easily remove and replace the elastic retaining ring 54 between the rib 62 and the wall of the housing 12.
  • the ring 54 is made of XC 75 steel on which two coatings are made: one Zn10ZB coating (yellow bichromate zinc) and a finishing coating for resistance to salt spray for 400 hours before the appearance of rust red.
  • the elastic retaining ring 54 may have profiles with different shapes.
  • the retaining ring elastic 54 has a truncated cone-shaped profile and in FIG. 5B the elastic retaining ring has a domed profile in the form of meniscus. It is intended that, preferably, the elastic retaining rings 54 and 56 are identical and have a constant material thickness.
  • This protective element 78 is preferably molded on the outside of the housing 12 and extends at least from the annular rib 38 of the ferrule 30 to the free edge of the first end 34 of the ferrule 30 in surrounding a section of the ferrule 30, the clamping ring 46 and a section of the first end 50 of the braid 26.
  • the protective element 78 constitutes a sleeve substantially cylindrical protecting the connection device throughout the area of the ferrule which is located outside the housing 12. It should be noted that this element protection 78 does not prevent the device from being dismantled fitting, by removing the elastic retaining ring 54 as will be described below.
  • the sheath 64 can then be shorter.
