Definitions

  • the invention relates to a lamp holder for receiving a glass base lamp according to the preamble of claim 1.
  • the prior art is based on a lamp holder (FR-A-2 356 292), in which an outer sleeve and an inner separating area are formed as a one-piece unit which isolates the contact elements from one another.
  • These contact elements are costly made of sheet metal and have to be arranged inside the lamp socket with increased assembly effort.
  • lamp holders (DE-AS 14 64 176, DE-AS 23 10 151) are constructed such that guides made of sheet metal are arranged within a sleeve, which have both spring elements and curved tracks. This also results in considerable assembly and cost expenditure for the production and arrangement of the individual metal elements in the interior of such a lamp holder.
  • the prior art also includes electrically conductive plastic, which contains a conductive component and can be processed, for example, by injection molding or transfer molding (DE-A-34 09 953, DE-A-33 05 401, DE-A 32 45 578, DE-A-32 38 246). These electrically conductive plastics can be used as composite bodies.
  • FIG. 1 Another prior art is a lamp holder for light bulbs with free wire ends or for light-emitting diodes (DE 37 27 515 A1).
  • An outer tube and an inner tube are used here, the free wire end of the light bulb being clamped to the outer tube by means of a clamping sleeve.
  • An insulating layer is arranged between the outer tube and the inner tube in order to separate the conductive outer tube from the conductive inner tube. Both tubes are smooth and require a special position-stabilizing connection, with the clamping sleeve also having to undergo additional fixation.
  • the present invention has for its object to design a lamp holder of the type mentioned in such a way that a simple, cost-saving structure is created, and in addition, the assembly effort should be kept low.
  • both contact elements each consist of an electrically conductive plastic material and the socket has an outer sleeve enclosing the contact elements and an inner separating region arranged inside the socket and isolating the contact elements from one another, eliminates the cost-intensive and expensive manufacture of the contact elements made of metal.
  • the outer sleeve and the inner separating area can be designed as a one-piece unit, the contact elements also being sleeve-like and can be inserted into the space between the outer sleeve and the inner separating area and into the interior of the inner area. There is a lock in this position.
  • the lamp holder 1 consists of two sleeve-like contact elements 8 and 9, an outer sleeve 10 enclosing these contact elements and an inner separating area 11 arranged inside the socket 1 and isolating the contact elements 8, 9 from one another.
  • the outer sleeve 10 and the inner separating area 11 formed as a one-piece unit.
  • the two contact elements 8 and 9 consist of an electrically conductive plastic material and are each designed like a sleeve.
  • the outer sleeve 10 is z. B. connected to the inner separation region 11 via three webs 12, 13, 14 arranged distributed over the circumference.
  • the outer sleeve-like contact element 9 is inserted in the intermediate space 15 between the outer sleeve 10 and the inner separating area 11.
  • the inner contact element 8 is inserted into the interior 16 of the inner separation region 11. Both contact elements 8 and 9 are arranged captively within the respective space 15 or 16.
  • both contact elements 8 and 9 designed like sleeves, each have at least one stop surface 19 or 20. These stop surfaces 19 and 20 can rest against a corresponding shoulder 17 and 18 of the outer sleeve 10 and the inner separating region 11.
  • the outer contact element 9 has at least one in the relevant web 12, 13 or 14 between the outer sleeve 10 and the inner separating region 11 of the slot 21 according to FIG. 4.
  • the outer contact element 9 has a neck-like bearing zone 23, which ends in a conical shape 24 on the end face.
  • This neck-like storage zone 23 is adjusted to the diameter of the storage area 22 of the glass base lamp 2 to be held according to FIG. 2a.
  • the bearing zone 23 can have either cylindrical shape 23 or profiled shape 23 '. It can also be seen from both figures that the outer contact element has at least one stop surface 19.
  • the inner contact element 8 shows the inner contact element 8. This has two blind holes 26 and 27 separated from one another by a partition 40.
  • the blind hole 27 is preferably divided by at least one slot 28.
  • the diameter of the blind hole 26 is adjusted to the diameter of the lamp base 25 of the glass base lamp 2 according to FIG. 2a; the diameter of the blind hole 27 of the inner contact element 8 is adjusted to the diameter of the lead 6 of the current-carrying lead part 5.
  • the lamp holder 1 according to FIG. 1, which is composed of the outer sleeve 10, the outer contact element 9, the inner contact element 8 and the inner separating region 11, is mounted in the correct manner, the glass base lamp 2 can be inserted from above, the bearing region 22 of the glass base lamp 2 being in the elastic bearing zone 23 of the outer contact element 9 stores.
  • the contact wire 3 acts on the inner contact element 8; the other contact wire 4 acts on the outer contact element 9.
  • the current-carrying lead part 5 can be inserted from below into the lamp holder according to the invention, the lead 6 being embedded in the lower blind hole 27 of the inner contact element 8.
  • the other lead 7 acts on the inner wall of the outer contact element 9 with its outer surface. A connection between the contact wires 3 and 4 of the glass base lamp 2 and the leads 6 and 7 of the current-carrying lead part 5 is thus established in a functionally correct manner.
  • the two contact elements 8 and 9 consist of electrically conductive plastic material, the overall design is considerably simplified with cost-saving assembly.
  • the abutment surfaces 19 and 20 of the inner and outer contact elements 8, 9 abut the corresponding shoulders 17 and 18 of the outer sleeve 10 and the inner separating area 11, respectively. This provides an exact adjustment of the individual elements within the outer sleeve 10 of the lamp holder 1 according to the invention.
