Definitions

  • the invention relates to an electric lamp with a sleeve-shaped base, in which a holding member for receiving the lamp bulb is arranged, which has a cover plate, adjacent to the inner wall of the base parts and openings, which when inserting the holding member into the base with grip this connected, inwardly projecting nock.
  • an electric lamp with a cover plate is known (Art. 54 (2) EPC), which has a rectangular recess with pressed out and resiliently attached to the pinch of the lamp bulb retaining tabs.
  • the cover plate itself is connected to the sleeve-shaped base by soldering or interlacing.
  • the invention has for its object to provide an electric lamp, the base and holding member without additional heat treatment, such as. B. welding or soldering can be connected.
  • jacket parts are at least two resilient tabs abutting the inner wall of the base, each with an opening corresponding to the cam cross section.
  • the cams are preferably designed as projections pressed out of the metal base sleeve.
  • the cams can also be designed as pins which protrude inwards and are fastened to the base.
  • the lamp bulb essentially has a pinch extending into the base with at least the height of the cams rectangular cross-section, which is arranged at least with one of its narrow side surface opposite one of the resilient tabs of the inner part in such a way that its distance from the cam protruding through the tab opening is smaller than the thickness of this tab.
  • the inner part with its resilient tabs must be inserted into the base and locked there with the cams before the lamp bulb is fastened in the inner part.
  • the lamps according to the invention can be light bulbs usable in motor vehicles, e.g. B. tail lights or flashing lights.
  • 1 is a z. B. tempered glass bulb of a small halogen incandescent lamp, which at its end has a cross section substantially rectangular pinch 2, in which power supply wires 3 and 4 are embedded to form a filament 5, the ends 6 and 7 of which protrude from the pinch 2.
  • a metallic inner part 8 which consists of a round cover plate 9 with three resilient tabs 10 extending at right angles thereto, which are each provided with round openings 11 (FIGS. 4 to 6).
  • the resilient tabs 10 are arranged on a circle, the diameter of which corresponds approximately to the inside diameter of a sleeve-shaped base 12 made of metal, into which the inner part 8 with its resilient tabs 10 is inserted in a closely fitting manner.
  • the base 12 has three inwardly pressed cams 13, of which only one is visible in FIG. 1 and two in FIG. 2. About these cams 13, the resilient tabs 10 engage when inserting the inner part 8 into the base 12 and snap with their openings corresponding to the cam cross section 11 locking one. This is the inner part. 8 mechanically firmly connected to the base 12.
  • the lamp bulb 1 is then inserted into the cover plate 9 of the inner part 8.
  • two retaining tabs 14 are bent obliquely inwards from the cover plate 9.
  • the pinch 2 is inserted until it stops against the piston 1.
  • the pinch 2 has, on its two longitudinal sides, extensions 16 which extend transversely to the longitudinal axis of the lamp, behind which the holding tabs 14 of the inner part 8, which are initially pressed apart by the pinch 2, snap into place when the lamp bulb 1 is inserted, as a result of which the lamp bulb 1 also faces in the axial direction the inner part 8 is secured (see, for example, DE-GM 7 526 777 or US Pat. No. 4,119,877).
  • the pinch 2 extending to at least the height of the cams 13 in the base 12 and thus the opening 15 in the cover plate 9 of the inner part 8 is arranged such that the pinch 2 with one of its narrow side surfaces 17 lies opposite one of the resilient tabs 10 of the inner part 8 such that its distance from the cam 13 projecting through the tab opening 11 is smaller than the thickness of this tab 10 is (Fig. 6).
  • FIGS. 7 to 12 show an embodiment of a lamp according to the invention, in which the inner part 8 is only provided with two resilient tabs 10 which cooperate with two base cams 13.
  • the same parts have the same reference numerals as in FIGS. 1 to 6.
  • the pinch 2 with its two narrow side faces 17, lies opposite each of the resilient tabs 10 of the inner part 8.
  • the holding tabs 14 pushed out of the cover plate 9 are bent at right angles; their mutual distance corresponds to the width of the pinch 2, which is in turn inserted into the opening 15 of the cover plate 9 until it stops against the piston 1.
  • the ends 6 and 7 of the power supply wires 3 and 4 are connected in the tensioned state to the base contacts 18 and 19, whereby the lamp bulb 1 is additionally secured in the axial direction.
