  • the first and second ends are each interconnected by a central portion and these middle portions of the two electrical terminals are embedded in the plastic of the base member such that the surfaces of the central portions are disposed in different planes perpendicular to the longitudinal extent of the headlight bulb, the second ends being of respective ones Central portion are angled, so that the surfaces of the second ends are arranged perpendicular to the surfaces of the respective central portion.
  • the electrical connections are on the one hand suitable for fixing the headlight lamp in the manner of a bayonet closure by a rotary movement about its longitudinal axis in the socket of the headlight and at the same time contacting it by means of its first ends and on the other hand the second ends of the electrical connections are aligned in such a way, that they are the same way as in the Laid-open publication DE 198 55 412 A1 is described, can be welded to the led out of the lamp vessel power supply wires.
  • the existing plastic base part is advantageously designed as a plastic injection molded part.
  • the middle sections of the electrical connections in the plastic material of this base part can be embedded by means of the injection molding technique.
  • the second ends of the electrical connections are preferably each provided with a groove in order to be able to fix the power supply wires protruding from the lamp vessel therein before the welding connection is established.
  • Headlamp is a halogen bulb of the type H11 lamp, which is used in a motor vehicle headlight, for example, to produce the low beam, high beam or fog light.
  • This lamp has a glass lamp vessel 1 with a sealed end 10, which is anchored in a base 2.
  • a sealed end 10 In the interior of the lamp vessel 1, an axially aligned filament 3 is arranged, the filament outlets are each connected to a led out of the sealed end 10 power supply wire 4, 5.
  • the base 2 is a so-called metal-plastic base. That is, he has both metallic and plastic existing base parts.
  • the sealed end 10 of the lamp vessel 1 is anchored in the metallic base part 20.
  • the metallic base part 20 is in turn fixed in the existing plastic base part 21, which is provided with two electrical terminals 6, 7.
  • the electrical connections 6, 7 each consist of a metal sheet and each have a first, provided with a contact surface end 61, 71 which protrudes in the radial direction from the plastic base part 21, so that the contact surfaces of these ends 61, 71 in different planes perpendicular are arranged one above the other or side by side to a small distance to the longitudinal axis of the headlight lamp.
  • FIGS. 1 to 4 show details of the existing plastic base part 21 and formed as a contact lugs electrical connections 6, 7 of the headlamp.
  • This in FIG. 1 illustrated base part 21 consists of a thermoplastic material and is designed as a plastic injection molded part.
  • the electrical connections 6, 7 are embedded in the material of the base part 21 by means of the plastic injection molding technique.
  • the plastic base part 21 is pot-shaped and at the bottom, that is, equipped on the side facing away from the lamp vessel 1 side with a handle portion 210.
  • the first ends 61, 71 of the electrical connections 6, 7 protrude out of the plastic base part 21.
  • the two electrical connections 6, 7 each consist of a metal sheet and are formed as one-piece contact lugs of different shape.
  • the closer to the handle portion 210 arranged first contact lug 6 has a first end 61 which is equipped with a flat, aligned perpendicular to the longitudinal axis of the lamp contact surface.
  • the first end 61 projects out of the base part 21. It is connected to the second end 62 by the central portion 60.
  • the surfaces, that is, the two sides of the central portion 60 have the same orientation as the planar contact surfaces or surfaces of the first end 61.
  • the surfaces of the central portion 60 are arranged after mounting in the base part 21 perpendicular to the longitudinal axis of the lamp ,
  • the second end 62 is angled away from the central portion 60 so that the surfaces, that is, the two sides, of the second end 62 are perpendicular to the surfaces of the central portion 60.
  • the second end 62 is aligned parallel to the longitudinal axis of the headlight lamp.
  • the second end 62 is provided with a groove 63 in which an angled end of the power supply wire 5 is fixed by means of welding.
  • the second contact lug 7 has a first end 71, which is equipped with a flat, aligned perpendicular to the longitudinal axis of the lamp contact surface.
  • the first end 71 protrudes from the base part 21. It is connected to the second end 72 by the step-shaped middle section 70.
  • the surfaces, that is, the two sides of the central portion 70 have the same orientation as the flat contact surfaces or surfaces of the first end 71. That is, the two sides, here top and bottom, of the central portion 70 after mounting in the base part 21st are arranged perpendicular to the longitudinal axis of the lamp.
  • the second end 72 is angled away from the central portion 70 so that the surfaces, that is, the two sides of the second end 72 are arranged perpendicular to the two sides of the central portion 70. After mounting the contact lug 7 in the base part 21, the second end 72 is aligned parallel to the longitudinal axis of the headlight lamp.
  • the second end 72 is provided with a groove 73 in which an angled end of the power supply wire 4 is fixed by means of welding.
  • FIG. 4 is the relative spatial arrangement of the two contact lugs 6, 7 shown schematically.
  • the individual sections of the two contact lugs 6, 7, that is, the two sides of their first ends 61, 71 and their central portions 60, 70 and their second end 62, 72 are each aligned parallel to each other.
  • the middle sections 60, 70 are embedded in the plastic base part 21 by means of injection molding technology.
