Definitions

  • the present invention relates to a converter housing, in particular for an electronic converter for halogen lamps, with a housing base body for receiving electronic components and a terminating element with a cable support for supporting at least one electrical connection cable.
  • Independent electronic converters are required to operate halogen lamps with the usual power network, for example.
  • two types of converters are used.
  • converters with spatially separated and opposite connection points for the network and lamp-side cabling on the other hand converters in which the connection points for the network and lamp-side cabling are in a close spatial relationship and are arranged next to one another. Due to this different design of the two converter types, they also differ in the design of their housing.
  • the converter housing has two cover caps, each of which covers a connection point and is arranged at the opposite ends of the housing. In the latter case, only a cover cap hides the two spatially closely arranged connection points at one end of the housing.
  • Converter housings for converters with a connection point for the network and lamp-side cabling can be designed to be approx. 40 mm shorter due to the omission of a connection point with the same board area for the electronic components. It is also possible to introduce some of these known converters into low false ceilings.
  • the converter housing types mentioned in Table 1 are mentioned here as examples.
  • the usable board areas and the usable housing volumes are very small.
  • the electronic components must therefore be mounted very close to one another or even one above the other. As a result, mechanical component placement is no longer possible.
  • manual assembly of the components leads to a higher probability of errors and higher assembly costs.
  • the strain reliefs of the known housing are only designed for connection cables with a diameter of up to a maximum of 7 mm.
  • the cables common in building installations have an outside diameter of up to 11 mm. Subsequent installation in false ceilings over the prepared cutouts of recessed lights is also not possible due to the cuboid design of these known converter housings.
  • a basic housing body and a terminating element are arranged vertically to one another.
  • the vertical arrangement of these two elements ensures that a larger usable board area is created by accommodating larger boards and a higher usable housing volume.
  • the basic housing body faces the one opposite the end element End an end surface rounded towards its underside. The rounding off of this end of the basic housing body ensures that the converter housing or the converter can be mounted in the ceiling using a conventional ceiling cutout of a recessed luminaire with low false ceilings.
  • the basic housing body is essentially cylindrical.
  • two mutually parallel, flat surfaces can be formed as a floor and ceiling element parallel to the cylinder axis of the basic housing body. Due to the cylindrical basic shape of the basic housing body, the effectively usable board area or the housing volume is further increased.
  • the end element has rounded and / or outwardly curved side walls on its underside. This geometric design of the side walls of the end element further facilitates the assembly of the converter housing according to the invention via small ceiling openings or the like.
  • this has a closure cap for covering a cable space formed by the terminating element.
  • This cap can be rounded towards the bottom of the closure element and / or curved.
  • This special geometric design of the sealing cap also serves for easy subsequent assembly of the converter housing according to the invention.
  • the housing base body is rounded at at least one transition between at least one side wall of the housing base body and the bottom and / or ceiling element of the housing base body.
  • the transition too between the end surface 18 and the floor and / or ceiling element can be rounded.
  • a curvature of the side walls of the basic housing body advantageously brings about a further increase in the usable housing volume and the board area to be accommodated in the converter housing.
  • a groove is formed in the bottom element of the basic housing body, which extends beyond the bottom element into the underside of the closing element.
  • a mains-side electrical connection cable can advantageously be inserted into this groove, as a result of which the insertion of the converter or the converter housing during assembly in e.g. False ceilings is further facilitated.
  • a converter housing 10 shown in FIG. 1 in a perspective overall view has a housing base body 12, a closure element 14 and a closure cap 16.
  • the basic housing body 12 and the end element 14 are arranged vertically to one another. It can be seen that at the end of the housing base body 12 opposite the end element 14, an end surface 18 rounded toward its underside is formed.
  • the housing base body 12 has an essentially cylindrical geometry. Parallel to the cylinder axis of the basic housing body, two mutually parallel, flat surfaces are designed as floor and ceiling elements 22 and 24.
  • the housing base body 12 which is used to hold electronic components, has an opening at the end opposite the end face 18 for receiving the closure element 14.
  • a perforated partition 32 connects the housing base body 12 to the closing element 14 having a smaller diameter.
  • the housing base body 12 and the closing element 14 can be detachably connected via a snap connection (not shown).
  • a circuit board and further electronic components are arranged in the interior of the housing volume formed by the housing base body 12 and the closure element 14.
  • the end element 14 has a cable support 46 for supporting at least one electrical connection cable.
  • the end element 14 has rounded and / or outwardly curved side walls 48 on its underside.
  • the side walls 48 are ribbed in the exemplary embodiment.
  • the closure cap 16 serves to cover the cable space 50 formed by the end element 14 (cf. also FIG. 3).
  • the closure cap 16 is rounded toward the bottom of the closure element 14 and / or curved.
  • the closure cap 16 has a first recess 36.
  • This first recess 36 corresponds to a corresponding second recess 38 on the underside of the closure element 14.
  • These two corresponding recesses 36, 38 serve to facilitate the fastening of the converter housing 10 via a fastening element (not shown) to e.g. a ceiling of a building or a false ceiling.
  • an opening 28 for receiving a fastening element 30 is formed in the closure cap 16.
  • the closure cap 16 Via the fastening element 30, which engages in a corresponding receiving opening (not shown) of the closure element 14, the closure cap 16 is detachably fastened to the closure element 14.
  • the closure cap 16 serves not only to cover the cable space 50 formed by the end element 14, but also to relieve the strain on the electrical connecting cables.
  • the closure cap 16 is designed to be pivotable on the end element 14 and thus allows the simultaneous strain relief of a cable with an 8 mm outer diameter (e.g. silicone cable for lamp wiring) and a cable with an 11 mm outer diameter (e.g. NYM cable for the house installation).
  • the fastening of the closure cap 16 via only one central fastening element 30 additionally results in an assembly and cost advantage.
  • Table 2 Dimensions and other parameters of the converter housing according to the embodiment Embodiment Dimensions [mm] 108x52x33 insertable in false ceiling * Yes usable board area [cm 2 ] 31 1 usable housing volume [cm 3 ] 90 suitable for cables with max ⁇ [mm] 11 *) free height of the false ceiling: 60 mm; Diameter of the cut-out: 55 mm
  • the converter housing 10 has a significantly increased usable board area and a significantly increased usable housing volume despite a shorter length.
  • the converter housing 10 can be inserted into a false ceiling and is suitable for cables with a maximum cable diameter of 11 mm.
  • Figure 2 shows another overall perspective view of the converter housing 10. It can be seen that the end face 18 towards the underside, i.e. rounded to the bottom element 22 of the housing base body 12.
  • the side walls 26 arranged between the floor element 22 and the ceiling element 24 of the basic housing body 12 are curved toward the outside. Furthermore, it can be seen that both the side walls 48 of the closure element 14 and the closure cap 16 are rounded toward the underside of the closure element 14.
  • the side walls 48 have ribs 34 which ensure easier and safe handling of the end element 14.
  • the curvatures of the base body end surface 18 and the closure cap 16 and the curved course of the side walls 48 of the closure element 14 are precisely matched to the insertion of the converter housing 10 into a false ceiling.
  • the false ceiling has circular cutouts with a diameter of approx. 55 mm.
  • the cylindrical body on which the converter housing shape is based has a diameter of 52 mm.
  • FIG. 3 shows a front view of the converter housing 10.
  • the cylindrical basic shape of the housing base body 12 can be seen with two outwardly curved side walls 26 as well as a flattened bottom element 22 and a flattened ceiling element 24.
  • the housing base body 12 is followed by the closure element 14 with the likewise curved side walls 48 . It can be seen that in each case two semicircular recesses in the cable support 46 and in the closure cap 16 form two openings 40, 42 for the introduction of electrical connecting cables.
  • the closure element 14 tapers in the direction of the side opposite the housing base body 12. This further facilitates subsequent insertion of the converter housing into corresponding ceiling openings.
  • FIG. 4 shows a rear view of the converter housing 10.
  • the characteristic and already described geometric shape of the housing base body 12 can again be seen.
  • the housing base body 12 is rounded off at least at one transition between the end face 18 and the floor and ceiling element 22, 24 is trained. In the exemplary embodiment, this is represented by the transition 20 between the end surface 18 and the base element 22.
  • the housing base body 12 may be rounded at at least one transition between at least one side wall 26 of the housing base body 12 and the floor and / or ceiling element 22, 24.
  • FIGS. 5 and 6 each show a side view of the converter housing 10.
  • the geometry which is matched to the easy assembly of the converter or converter housing 10 can again be seen.
  • the undersides of the basic housing body 12 and the end elements 14 are in one plane with one another, the end element 14 being covered by a closure cap 16.
  • the basic housing body in turn shows two flattened elements 22 and 24 and the end surface 18 rounded towards its underside. In the transition 20 between the end surface 18 and the bottom element 22, the latter is rounded.
  • the converter housing 10 is shown in a plan view.
  • the curvature of the side walls 26 of the housing base body 12 and the rounding of the end face 18 in the direction of the underside of the housing base body 12 can also be seen.
  • the end element 14 tapers towards the end opposite the housing base body 12.
  • the recess 36 in the closure cap 16 and the corresponding second recess 38 in the closure element 14 serve to receive a fastening element, not shown, for fastening the entire converter housing to, for example, a ceiling of a building.
  • the converter housing 10 can are attached before or after the assembly of the cap 16.
  • the fastening element 30 serves to fasten the closure cap 16 to the closure element 14.
  • FIG. 8 shows a view from below of the converter housing 10. It can be seen that a groove 44 is formed in the bottom element 22, this groove 44 extending beyond the bottom element 22 into the underside of the end element 14. The groove 44 serves to receive the mains-side connection cable, which further facilitates the assembly of the converter housing 10 or the converter.
