Definitions

  • the present invention relates to a connector for a lamp discharge in particular for motor vehicle.
  • such a connector comprises a socket which is intended to receive the base of the discharge lamp and which has in its inside two metallic contact elements connected to a circuit discharge lamp supply (or "ballast").
  • a circuit discharge lamp supply or "ballast"
  • connectors have already been proposed comprising their interior an elastic contactor which does not close the supply circuit on the contacts only when it is pushed back by the fitting of a lamp discharge in the connector.
  • connectors have been proposed in which the metal contacts inside are, in the absence of a lamp, covered by a removable electrically insulating element, which is pushed back and retracted when a lamp is inserted in the connector.
  • An object of the invention is to propose a solution which does not present not these different drawbacks.
  • a connector for a discharge lamp in particular of a motor vehicle comprising at least two contacts electrics for supplying high voltage and low electrodes voltage of said lamp, characterized in that it comprises means which impose - for the arcs by which the power module to which the connector is connected discharges when it energizes said contacts and that no lamp is in place in the connector - a path preferential other than a direct path between these contacts.
  • the circuit of FIG. 1a comprises a discharge lamp 1 which has two electrodes, one low voltage, the other high voltage, which are respectively connected to the supply circuit of the discharge lamp by means of electrical contacts 2 and 3 which the connector. These two contacts 2 and 3 are designated by high contact voltage and low voltage contact in the rest of the text.
  • This circuit also comprises a metallic element 4 which, when no lamp is in place in the connector, is arranged in this near the high voltage contact 2.
  • This element 4 is connected to the low voltage contact 3 via resistive means 5.
  • the supply circuit priming module discharges preferably by an arc A - shown schematically by a double zigzag arrow in FIG. 1a - between the high voltage contact 2 and the element 4 which is connected to contact 3, but which is closer to contact 2 than is said contact 3.
  • resistive means 5 Furthermore, the intensity of the current of such an electric arc is limited by resistive means 5.
  • FIG. 1b Another possible embodiment has been illustrated in FIG. 1b.
  • two metallic elements are provided. 4a, 4b electrically connected respectively one to contact 2, the other to contact 3, for example by means of resistive means. These two metal elements 4a, 4b are arranged opposite one another, the distance between them being less than the distance between them contacts 2 and 3.
  • the priming module discharges preferably by an arc A between elements 4a and 4b, rather than by arcs between contacts 2 and 3.
  • Resistive means 5a, 5b are interposed between the elements 4a, 4b and the contact 2, 3 to which they are connected.
  • Figures 2a and 3a illustrate a connector structure corresponding to the variant of Figure 1 a.
  • the connector shown in these Figures 2a and 3a includes a housing 6 shaped so as to receive and maintain the base of a lamp discharge which is complementary.
  • the connector also includes above said bottom one or several metal contacts 3, which constitute the low voltage contacts of the connector and which are inserted in the wall 9 defining the housing interior which is intended to receive the base of the lamp. These contacts are intended to be supported on the ring of the discharge lamp when the latter is in place.
  • the wall 9 also incorporates a resistive wire 10 which connects the contacts 3 to an elastic metal tab, which constitutes element 4.
  • This elastic tab 4 is constituted by a metal blade which is folded back on itself and which extends from the wall 9 to the vicinity of the central skirt, being substantially in the diametrical plane in which extend the two metal strips which constitute contacts 2 high voltage.
  • the contacts 2 are closer to this elastic tab 4 than contacts 3.
  • This elastic tab 4 is thus positioned so that the plastic parts between the contacts are not damaged.
  • resistive means 5 limit the current of the arcs.
  • zones which correspond to the preferential paths of the arches are reinforced areas for show good resistance over time.
  • the elastic tab 4 also constitutes a low voltage contact.
  • Figures 2b and 3b illustrate a structure of connector corresponding to the variant of Figure 1 b.
  • This connector structure is substantially similar to the structure of Figures 2a and 3a.
  • the plan common to the two contacts 2 is there however turned a quarter turn, so that said contacts 2 are substantially aligned with contacts 3 ..
  • the metallic elastic tab - referenced by 4a instead of 4 - extends perpendicular to this common plane and the connector has further another metal element 4b consisting of a metal blade which extends in the height of the skirt 7 while being juxtaposed with said skirt 7 to inside of it.
  • This blade 4b is directly opposite the tab elastic 4a and the distance between said blade 4b and the end of said blade 4a being smaller than the distance between the contacts 2 and 3.
  • the means resistors which connect the tab 4b to the contact 2 (not shown in the figures 2b and 3b) are integrated in the bottom of the connector.
  • the resistive means 5 or 10 can be replaced by any other means allowing the current to be limited, for example by a VDR component. They can also be made up of a component resistive integrated into the wall 9 or even be constituted by the dimensioning of the element 4.
  • one or more metallic elements can be provided - which are not necessarily connected to the contacts and which do not constitute not elements on which the arcs are established - but which are arranged on the connector in such a way that they help to impose electric arcs a preferential path other than a path direct between connector contacts.
