Definitions

  • the invention relates to a cementless electric lamp according to the Preamble of claim 1.
  • European patent application EP-A 0 643 255 describes an electrical one Lamp with a strain relief for the connection cable, which by crimped Implementation rivets is formed.
  • the lead rivets are each threaded onto a connecting cable and then crimped, and are in the tapered cable bushings are embedded. This strain relief is comparatively complex to manufacture.
  • the electric lamp with a cementless base has a particular feature simple strain relief for your power supplies without additional Components.
  • the base stone consists according to the invention two base stone components slidably arranged against each other, whose relative position to each other the size or diameter of the bushings intended for the power supply.
  • the power supplies are clamped in the bushings.
  • the clamp seat is by the two aforementioned side walls of the base sleeve produced by the first Side wall against the first base stone component and the second side wall presses against the second base stone component.
  • the pressure of the two side walls mentioned above is advantageous to the base stone components and thus also the clamp fit of the power supply lines with the help of at least one inside the base sleeve pointing knob, which is attached to each of these two side walls, generated. Narrow clamping lugs that narrow the feedthroughs that connect to the Both base stone components are molded on, improve the press fit of the Power supply.
  • the base stone components are advantageously two identically shaped base stone halves. This simplifies lamp manufacturing.
  • the base stone components are advantageously fixed with the help of at least two fastening straps attached to different Shaped side walls of the base sleeve and angled from this are, as well as with the help of several attached to the base sleeve wall Stop knobs that serve as a stop for the base stone components.
  • the embodiment of the invention shown in FIG. 1 is concerned it is a current-controlled, cementless, low-voltage halogen incandescent lamp with an electrical power consumption of approx. 200 W and one Nominal current of approx.6.6 A, which can be used, for Airport is used.
  • This lamp has a lamp bulb 1 and a base which has a metallic base sleeve 2 with one fixed therein Has base stone.
  • the base sleeve 2 is cuboid, with two open End faces executed. In particular, it has two opposite one another narrow side walls 2a, 2b.
  • the base stone is made by two identically shaped, essentially F-shaped base stone halves 3a, 3b, which both consist of an electrically insulating ceramic.
  • the Both F-shaped base stone halves 3a, 3b are in this way in the base sleeve 2 introduced that their webs mesh and they two bushings 4, 5 form for the two power supply lines 6, 7 of the lamp.
  • the two Base stone halves 3a, 3b fill the base sleeve 2 in height. Indeed exists between the narrow side walls 2a, 2b and the base stone halves 3a, 3b a slight game, because the dimensions of the base stone halves 3a, 3b in this direction slightly smaller than the width of the Base sleeve 2, that is, as the distance between the side walls 2a, 2b. Thereby the base stone halves 3a, 3b are slightly against each other in this direction slidable.
  • the power supply lines 6, 7 partially run inside the base sleeve 2 and are each sealed with a gas-tight lamp bulb 1 Electrode (not shown) welded, which in turn is electrically conductive the filament (not shown) of the lamp are connected. You are 6, 7 provided with an electrically insulating sleeve and as a connection cable executed. Two narrow passages 4, 5 narrowing Increase clamping lugs 10, 11, which are molded onto the base halves 3a, 3b the clamping effect.
  • the base stone halves 3a, 3b are pointing into the base of the base with the help of four Stop knobs 12 and with the help of two on the narrow sides 2a, 2b molded and angled from this mounting tabs 13, 14 in the base sleeve 2 fixed.
  • the stop knobs 12 define the depth of penetration of the base stone halves 3a, 3b into the base sleeve 2, while the fastening tabs 13, 14 a falling out of the base stone halves 3a, 3b from the Prevent base sleeve 2.
