Definitions

  • the invention relates to a receptacle for the base of a mercury vapor low-pressure discharge lamp with a base on one side, which has a cam provided with a cam, wherein for mechanical mounting of the lamp resilient elements are arranged in the receptacle made of an insulating material, with their molded-in detents behind the cam of the cam click into place.
  • Such a receptacle is already described in DE-OS 31 21 077 and represents a version in which an approximately U-shaped metal strip is fastened within the socket body made of plastic for holding the lamp, the ends of which are bent into approximately semicircular locking lugs, which engage behind the cams on the guide pin when the lamp is inserted.
  • the proportion of metal parts within a socket should, if possible, be limited to the elements which make contact between the socket and the lamp base.
  • the object of the invention is to design the mechanical holder for the lamp in the receptacle in such a way that the use of resilient elements made of metal is avoided.
  • a receptacle for the base of a single-ended base mercury vapor discharge lamp in that the receptacle and the resilient elements are made in one piece, the lower ends of the resilient elements being connected to the receptacle and the play of the upper ends by one the molded stop is limited.
  • the upper ends of the resilient elements extend beyond the locking lugs, so that these - in contrast to the subject matter of DE-OS 31 21 077 - are arranged between the lower and the upper ends of the resilient elements.
  • the stop for the resilient elements formed on the receptacle is formed by the upper boundary surface of the receptacle.
  • the resilient elements are very slightly facing each other at rest with their upper ends.
  • the cams press the resilient elements apart until the upper ends of the base rest against the stop of the receptacle.
  • the cams of the guide pin are still in this position in front of the locking lugs of the resilient elements.
  • a certain force has to be overcome in order to be able to guide the cams past the locking lugs.
  • the resilient elements are pushed further apart.
  • the receptacle according to the invention can be used both as a mountable in a lamp and as a housing part of an adapter containing the ballast and ignition device for the lamp. Since the receptacle including the resilient elements are made of the same material and in one piece, the injection molding process is particularly suitable for the production.
  • the additional production and assembly of the metallic resilient elements according to the known version can be omitted, as a result of which tool, material and assembly costs are considerably reduced when the present invention is incorporated.
  • the electrical safety of the receptacle is improved compared to the known sockets, since the resilient elements engaging on the base and mechanically holding the lamp consist of an insulating material.
  • the mechanical mounting in the lamp in the holder is significantly improved, since material fatigue is excluded in the present construction.
  • the spread of the resilient elements and thus also the size of the force with which the base is held in the receptacle can be determined by the thickness of the cams on the base and / or by the inside width of the opposing stops.
  • the cap 1 shown in the figures is made of plastic (e.g. Pocan) by injection molding. It consists essentially of a recess 2 with a rectangular cross-section and a housing part 3 forming the upper boundary of the recess 2.
  • the recess 2 opens into an extension 4 in the upper region.
  • the resilient elements 5 with the locking lugs 8 are made in one piece with the cover cap 1 with the recess 2 and in one operation.
  • the upper end 7 of the resilient elements 5 ends with the lower boundary surface 9 of the extension 4.
  • a stop 10 is formed on the lower boundary surface 9 on each side, which limits the play of the resilient elements 5 to the outside.
  • the guide pin 11 of a lamp base is shown in dashed lines.
  • the guide pin 11 has a cross section adapted to the recess 2.
  • cams 12 are integrally formed on the guide pins, which engage behind the latching lugs 8 of the resilient elements 5 in the insertion direction, the resilient elements 5 due to the spreading force of the cams 12 their upper ends 7 are pressed against the stops 10. This ensures a secure mechanical mounting of the base in the receptacle.
  • the rectangular cross section of the depression 2 can be seen in the plan view shown in FIG. Furthermore, four holes 13 are visible in the lower boundary surface 9 of the extension 4.
  • the contact pins of the lamp base protrude through two or four of these bores 13 when the lamp is inserted, a different pin combination being used depending on the lamp output in order to ensure the correct adaptation to the ballast contained in the housing (also not shown).
