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 injection 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.
  • 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, with the free wire end of the light bulb using a clamping sleeve on the outer tube is clamped.
  • 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 thus advantageously each consist of an electrically conductive plastic material; the outer sleeve and the inner separating area designed as a connecting part are two separate units.
  • the two contact elements are identical, each with a half-shell with a clip-in area with a connection area protruding from the outer sleeve.
  • This construction results in a reduction in price, since 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.
  • a lamp holder 1 'shown in the individual figures serves to accommodate and functionally interconnect a glass socket lamp 2, shown schematically in FIG. 2a, with a current-carrying lead part, not shown in any more detail.
  • This glass base lamp 2 has two separate contact wires 3 and 4, a storage area 22 and a lamp base 25.
  • the lamp holder 1 ' accordinging to the invention consists of an outer sleeve 10' and an inner separating area 11.
  • the outer sleeve 10 'and the inner separating area 11 are designed as two separate elements, this inner separating area 11 being designed as a connecting part 28a (FIG. 2) is.
  • the two contact elements 8 'and 9' each consist of an electrically conductive plastic material known per se. They are of identical design and each have a half-shell 29 or 29 'with clip-in areas 33, 33' or 34, 34 'in the form of openings. 1 and 3 are molded onto the half-shells 29 and 29 ', which protrude beyond the outer sleeve 10' according to FIG. 1 and establish the electrical connection with a current-carrying lead part, not shown in detail.
  • the connecting part 28 which is designed independently of the contact elements 8 ', 9', has two locking elements 31, 31 'and 32, 32' on both sides. These four locking elements then make the connection to the two contact elements 8 ', 9' when they are in the clip-in areas 33, 33 'or. 34, 34 'are stored.
  • the locking elements 31 and 31 ' each engage in a clip-in area 34 and 34' of the upper contact element 8 ', while the locking elements 32 and 32' are embedded in 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 inside the outer sleeve 10 'for receiving part of the glass base lamp 2.
  • the connecting part 28a advantageously makes the two contact elements 8' and 9 ' spaced apart from one another on the connecting part 28a, this unit being located in the interior of the outer sleeve 10 '.
  • This design according to the invention results in a considerable reduction in cost, since the two contact elements have the same shape, can therefore be produced in a cost-saving manner and, moreover, can be connected to one another in an isolated manner via the connecting part 28a.
