Definitions

  • the invention relates to a lamp holder for receiving an incandescent lamp according to the preamble of claim 1.
  • a lamp holder for receiving an incandescent lamp is already known as prior art, in which guides made of sheet metal are arranged within a sleeve and have both spring elements and curved tracks (DE-OS 26 28 127, DE-AS 1 464 176, DE -AS 23 10 151). This 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.
  • electrically conductive plastic belongs to the prior art, which contains a conductive component and can be processed, for example, by injection molding or injection molding (DE-OS 34 09 953, DE-OS 33 05 401, DE-OS 32 45 578, DE -OS 32 38 246). These electrically conductive plastics can be used as composite bodies.
  • 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 given, in addition, the assembly effort should be kept low.
  • both contact elements each consist of an electrically conductive plastic material and the socket an outer sleeve surrounding the contact elements and one inside the socket ordered, the contact elements from each other insulating inner separation area, the cost-intensive and expensive manufacture of the contact elements made of metal is eliminated.
  • the outer sleeve and the inner separating area can be designed as a one-piece unit.
  • the contact elements are also each sleeve-like and can be inserted on the one hand into the space between the outer sleeve and the inner separation area and on the other hand in the interior of the inner separation area, with a locking being provided in this position.
  • the outer sleeve and the inner separating area designed as a connecting part are designed as two separate units.
  • the two contact elements can advantageously be identical, each with a half-shell with a clip-in area and a connection area protruding from the outer sleeve. This construction leads to a further reduction in the cost in that the two contact elements have the same shape and are connected to one another in isolation via the connecting part. This unit is then placed inside the outer sleeve.
  • the first embodiment of a lamp holder 1 shown in FIG. 1 serves to accommodate and functionally interconnect a glass base lamp 2 with current-carrying lead part 5 shown in FIGS. 2a and 2b.
  • This glass base lamp 2 has two separate contact wires 3 and 4, one
  • the current-carrying supply part 5 has two supply lines 6 and 7 which are isolated from one another.
  • the lamp holder 1 consists of two sleeve-shaped contact elements 8 and 9, an outer sleeve 10 surrounding these contact elements and an inner separating region 11 arranged inside the socket 1 and isolating the contact elements 8, 9 from one another.
  • the outer sleeve 10 and the inner separating region 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, for. 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 glass base lamp 2 can be inserted from above, the storage area 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 entering the lower blind hole 27 of the inner contact element 8 stores.
  • 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 are made 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.
  • the outer sleeve 10 'and the inner separation area 11' are designed as two separate elements, this inner separation area 11 'being designed as a connecting part 28a.
  • the two contact elements 8 'and 9' are identical and each have a half-shell 29 or 29 'with clip-in areas 33, 33' or 34, 34 '.
  • On the half-shells 29 'and 29' are formed connecting parts 30 and 30 ', which protrude beyond the outer sleeve 10' of FIG. 10 and establish the electrical connection with a current-carrying part, not shown,.
  • the connecting part 28a has two locking elements 31, 31 'and 32, 32' according to FIG. 11 on both sides. These four
  • Locking elements establish the connection to the two contact elements 8 ', 9'.
  • the locking elements 31 and 31 ' engage in the respective clip-in areas 34 and 34' of the upper contact element 8 ', while the locking elements 32 and 32' are embedded in the corresponding clip-in areas 33 and 33 'of the lower contact element 9'.
  • the connecting part 28a and the two contact elements 8 'and 9' form an intermediate space 35 in the interior of the outer sleeve 10 'for receiving part of a glass base lamp 2.
  • the connecting part 28a insulates the two contact elements 8' and 9 'at a distance from one another on the connecting part 28a, this unit being arranged in the interior of the outer sleeve 10 '.
  • This design also advantageously results in a simple and cost-saving construction of the lamp holder according to the invention.
