Definitions

  • the invention relates to a transformer, in particular an electronic one Transformer for halogen ceiling spotlights, with those in the preamble of claim 1 specified features.
  • halogen spotlights in suspended Provides false ceilings.
  • Such halogen downlights are in the Usually operated with low voltage, so that for their voltage supply a transformer, in particular an electronic transformer with a Coil arrangement and an associated electronic wiring unit is to be provided.
  • transformer housings have enough on the one hand Space for a mechanized and inexpensive assembly of the electronic Components and the coil arrangement as well as for easy assembly the connecting cables commonly used in building installations with a diameter of up to 11 mm.
  • transformers due to their dimensions and their elongated, rectangular housing shape through in the Usually introduce round ceiling cutouts for halogen recessed ceiling spotlights. This applies in particular to a small distance between the suspended false ceilings and the main ceiling above. This distance should also be kept as small as possible to avoid loss to limit space height when installing a false ceiling.
  • the transformer housing shown there still has an essentially flat, cuboid basic shape, but the narrow longitudinal and transverse sides of the housing are rounded off over its full height. So bulbous narrow sides are used, the one Threading "of the housing into the false ceiling by the conventionally circular ceiling cutouts make it easier or even possible at all.
  • the invention has for its object to provide a transformer the housing of which is simple to insert into false ceilings relieved, but the structure of the electronic circuit and imposes no disturbing restrictions on the coil assembly.
  • the intended housing features an indentation on a broad side of the housing and a bevel at the longitudinal end of the opposite broadside make it possible on the one hand, the housing in a kind of swivel-in process through a ceiling opening to be inserted into a false ceiling.
  • the flat, rectangular basic shape of the housing can be maintained still a flat board for the construction of the electronic wiring unit be used.
  • the indentation divides the Housing interior in two sub-rooms, one of which for the coil arrangement and the other for the construction of the electronic wiring unit and the supply of the connection elements of the transformer is used can be. In this respect, the result is a clean and logical one Product design.
  • the electronic transformer shown has a multi-part housing for halogen recessed ceiling spotlights 1 on that a substantially flat-cuboid basic shape with a lower broad side 2, an upper broad side 3, in between in the longitudinal direction 4 and vertical to the broad sides 2, 3 narrow sides 5, 6 and vertical and transverse 7 transverse sides 8, 9 shows.
  • Approximately the housing 1 is centered on its underside in relation to its longitudinal direction 4 provided with an indentation 10, which extends from the lower broad side 2 goes out and passes completely through the housing 1 in the transverse direction 7.
  • the indentation 10 is therefore open on both sides towards the narrow sides 5, 6.
  • the indentation extends 10 to a depth t that is slightly larger than half the case height h is into the housing 1.
  • the boundary wall 12 lying on the side of the bevel 11 Indentation 10 is also designed as a type of ramp, which in one acute angle W of about 25 ° to the main extension plane E of the lower Broadside 2 runs.
  • the opposite boundary wall 13 of the indentation - So the boundary wall 13 on the bevel 11th facing away from the recess 10 - is substantially rectangular arranged to the main extension plane E of the lower broadside 2 and merges into the broadside 2 in a rounding 14.
  • this boundary wall 13 is in the transverse direction 7 of the housing convex curved.
  • the convex shape of the boundary wall 13 is finally by the transverse side 9 of the housing facing away from the bevel 11 1 added, which is also convexly curved in the transverse direction 7 runs.
  • the housing 1 consists of a practically the upper half Ceiling shell 15 and two arranged one behind the other in the longitudinal direction 4
  • Bottom shells 16, 17, which are connected by corresponding locking elements 18 are releasably connected to the ceiling shell 15.
  • the parting line F between the two bottom shells 16, 17 run approximately halfway up the boundary wall 12 in the transverse direction 7.
  • connection openings next to each other 20 are in the housing 1 in front of the connection openings 20, 21st each protruding inwards on the bottom shell 17 and the top shell 15 Ribs 22, 23 are provided, which act on the cables and locked in place Condition of floor pan 17 and ceiling pan 15 for strain relief serve the cable.
  • 3 and 4 are other internal structural parts recognizable, which are not relevant to the present invention are and therefore need not be explained in more detail.
  • circuit board 24 in front of the upper broad side 3 inside the housing indicated on which the transformer coil assembly 25 and the associated electronic wiring unit 26 are arranged.
  • the coil arrangement 25 is in the essentially flat cylindrical space between indentation 10 and the transverse side facing away from the bevel 11 9 housed.
  • the wiring unit 26 uses the space above and beyond the indentation 10.
  • FIG. 5 shows the assembly of a transformer designed according to FIGS. 1 to 4 in an intermediate space 27 which lies between a main ceiling 28 and a suspended intermediate ceiling 29.
  • the false ceiling 29 is used to install halogen ceiling recessed spotlights, for which the false ceiling 29 is provided with a circular installation opening 30.
  • the diameter D of the installation opening 30 is - depending on the type of recessed spotlight - between 50 and 80 mm.
  • the transformer shown can be inserted through an installation opening 30 with a diameter of 58 mm into an intermediate space 27 with a height Z of 28 mm.
  • the housing 1 is pushed with the tip region 19 forward from below into the installation opening 30 and threaded into the intermediate space 27.
  • the indentation 10 is responsible.
  • the adjacent edge 31 of the installation opening 30 can enter the latter until the transformer is inserted so far that the rear transverse side 9 passes the opposite edge 32 5.
  • This intermediate position is shown in broken lines in Fig. 5.
  • the transformer only has to be moved within the space 27 in the direction of arrow 33 until the installation opening 30 is free for the installation spotlight (not shown) that in Fig. 5 the already attached connection cables for the transformer have been omitted for the sake of clarity.
  • the dimensions can of course be used for transformers of lower power can still be reduced so that the diameter of the installation opening 30 and / or the height Z of the space 27 is even smaller can be held.
