Definitions

  • the invention relates to an electric lamp with a sleeve-shaped base into which a holding device carrying the lamp bulb is inserted.
  • the base and the holding device are connected to one another after assembly by soldering or welding. Such connections are cumbersome and expensive. that when using thin wall thicknesses, the material can be destroyed during spot welding.
  • the invention is therefore based on the object.
  • the base and holding device can be connected to one another without additional heat treatment, such as welding or soldering.
  • the sleeve-shaped base has at least two inwardly projecting cams
  • the holding device is a cylindrical sleeve, which is provided on its cylinder jacket with at least two slot-like recesses extending in the lamp axis up to its inner edge, and that Grip recesses over the cams.
  • the cams are preferably designed as projections pressed out of the metal base wall.
  • the cams can also be designed as pins which protrude inwards and are fastened to the base
  • the slot-like cutouts expediently widen towards the edge. In this way, the base and the holding device can be easily assembled without prior precise alignment of the two parts to one another
  • the slot-like recesses can be provided with resilient tabs which are pushed apart by the base cams when the inner sleeve is inserted into the base and spring back behind the cams in the position of the holding device.
  • the resilient tabs of the inner sleeve practically snap into place behind the base cams and thus ensure that the inner sleeve is firmly seated in the base, even in the axial direction.
  • the tabs can e.g. B. consist of inwardly bent resilient edge parts of the adjoining the slit-like recesses of the cylindrical sleeve of the l laltvorrirhtung.
  • incandescent lamps can be used in motor vehicles.
  • 1 and 2 is 1 em z.
  • the holding device 9 is on your cylinder jacket 12 with which in the lamp axis up to the inside of the base Edge 13 extending slot-like recesses 14 which expand towards the edge 13.
  • the holding device 9 is arranged closely fitting in a sleeve-shaped base 15 made of metal.
  • the base 15 has two inwardly pressed cams 16, via which the slot-like recesses 14 of the holding device 9 engage when they are inserted into the base 15.
  • the holding device 9 is pushed into the base 15 until the base cams 16 abut the end of the slot-like recesses 14 in the cylinder jacket 12 of the holding device 9.
  • the ends 6 and 7 of the power supply wires 3 and 4 are then soldered to the base contacts 17 and 18 in a tightly tensioned state, as a result of which the holding device 9 is also secured in the base 15 in the axial direction.
  • FIGS. 6 to 11 show an embodiment of a lamp according to the invention, in which the axial securing of the holding device in the lamp base takes place differently.
  • the same parts have the same reference numerals as in FIGS. 1 to 5.
  • the holding tabs 10 in the cover plate 8 of the holding device 9 are not bent at right angles, but are only bent obliquely inwards.
  • the pinch 2 of the lamp bulb 1 has, on its two longitudinal sides, projections 19 extending transversely to the lamp longitudinal axis, behind which the obliquely bent retaining tabs 10 of the holding device 9 latch in a locking manner when the lamp bulb 1 is inserted (cf. e.g. DE-GM 7 526 777 or U.S. Patent 4,119877).
  • the holding device 9 is in turn provided with slot-like recesses 24 which extend to the edge 13 of the cylinder jacket 12 of the holding device 9.
  • the slot-like recesses 24 have in their central region inwardly projecting resilient tabs 20, which consist of inwardly bent edge parts of the cylinder jacket 12 of the holding device 9 adjoining the slot-like recesses 24.
  • These resilient tabs 20 slightly reduce the width of the cutouts 24, but are pushed apart by the cams 16 when the holding device 9 is inserted into the sleeve-shaped base 15 and spring back in the end position of the holding device 9 behind the cams 16, thereby axially securing the holding device 9 is reached in the base 15 (Fig. 7).
