Description

The invention relates to an operating device for lamps, which has a housing and at least one electrical or electronic assembly, the housing consisting of at least one device base on which the assembly is arranged.

An operating device for lighting means can be understood, for example, as a ballast, which designates a device required in gas discharge lamps and fluorescent lamps, in particular for current limitation.

Numerous configurations for housings of electronic operating devices are known from the prior art. For example, in the pamphlet WO 01/31 980 A1 an electronic ballast for a gas discharge lamp is shown, which has a plate-shaped base part on which electronic assemblies are arranged and a box-shaped cover with which the ballast can be closed. In order to dissipate the lost heat, the base plate has a plate-shaped, metal cooling element, which is introduced into the base plate in the course of the sharpening process for producing it. A base screw connection of the version shown in this publication for a ballast is provided on the respective end faces, on which the strain relief for the wiring of the device is also located. This can possibly lead to problems with the screw connection, as this is obstructed by the wiring of the device. Additional measures may therefore be necessary to ensure adequate insulation of the fastening elements from the cables routed over them.

In the pamphlet U.S. 5,762,509 A a housing is shown in which a printed circuit board can be accommodated. The printed circuit board partially rests on a connecting element. The connecting element is in turn connected to a lower housing part.

In the pamphlet DE 100 10 356 C1 a ballast is shown in which a printed circuit board connected to a terminal is inserted into the terminal via a latching element in a housing.

In the pamphlet DE 202 15 425 U1 shows a housing for a printed circuit board, the housing showing a box-shaped lower housing part and a box-shaped upper housing part which can be placed on the lower housing part. At least two opposite side walls of the lower part of the housing have areas that are angled outwards at an angle near the bottom, on which a printed circuit board can be arranged at a defined distance from the bottom of the housing. Fastening lugs are also formed in the housing cover, by means of which the housing can be fastened to a base on the bottom side only in the assembled state.

Accordingly, it is the object of the invention to provide an operating device for lighting means, the housing of which is simple in construction and versatile in use.

This object is protected by the features of the independent claim. The dependent claims develop the central idea of the invention in a particularly advantageous manner.

According to a first embodiment of the invention, the operating device for lighting means has a housing and at least one electrical or electronic assembly. The housing consists of at least one device base on which the at least one assembly is arranged. The device base in turn has a base part and a side wall which are formed integrally with one another. The side wall protrudes from the base part in such a way that the device base is L-shaped.

In a second embodiment of the invention, the operating device for lighting means has a housing and at least one electrical or electronic assembly. The housing consists of at least one device base on which the at least one assembly is arranged. The appliance base in turn has a base part and at least two side walls which are formed integrally with one another. The side walls protrude from the base part in such a way that the device base is designed in a U-shape.

The side wall advantageously has at least one fastening device with which the operating device can be fastened.

Further advantageously, the assembly is mounted on the base part of the device base.

The base part advantageously has a grounding pin. In a particularly advantageous embodiment, this grounding pin is formed integrally with the base part. The grounding pin preferably extends away from the base part in the same direction as the side wall of the device base.

The base part and the side wall are integrally connected to one another via a step, the shoulder of which extends essentially parallel to the base part is directed. A part of the assembly that requires particularly good heat dissipation lies flat on the shoulder of the step.

Advantageously, the bottom of the device is made of a material that conducts heat well, preferably aluminum.

Advantageously, the operating device also has a housing upper part which, together with the device base, completely encloses the at least one assembly.

In a first embodiment, the upper part of the housing is placed on the bottom of the device so that the fastening device is freely accessible from the outside.

In a second embodiment, the upper part of the housing completely encloses the device base and the assembly. The upper part of the housing is preferably formed in at least two parts from a base part and a cover part. The upper part of the housing preferably has a tapering waist. Furthermore, the upper part of the housing preferably has at least one strain relief on a side on which the side wall of the base part is not arranged. In a preferred embodiment, the strain relief is arranged at an acute angle to the corresponding side of the upper part of the housing.

The operating device advantageously has at least two strain reliefs which are arranged in a fan shape in relation to one another.

The upper part of the housing preferably has a fastening device for fastening the bottom of the device in or on the upper part of the housing.

The upper housing part preferably has a fastening device for fastening the operating device, which is arranged on the opposite side of the upper housing part that has the strain relief.

The cover part is preferably formed in at least two parts from a cover part and a pivoting part, the pivoting part also preferably being pivotably connected to the cover part and being pivotable into defined, latched rotational positions.

The strain relief preferably has a strain relief pusher for blocking a cable, by means of which latching lugs in the base part can be prestressed for locking the pivoting part with the base part.

The cover part advantageously has a cooling plate.

The device base of the operating device for lamps according to the first embodiment has a base part and a side wall which are formed integrally with one another, the side wall protruding from the base part in such a way that the device base is configured in an L-shape. The device base of the operating device for lamps according to the second embodiment has a base part and at least two side walls which are formed integrally with one another, the side walls protruding from the base part in such a way that the device base is U-shaped.

The base of the device can thus be produced very simply and in a material-saving manner, for example in a stamping and forming process. Furthermore, a correspondingly designed operating device is particularly handy due to the side wall extending from the base part, so that damage to the assembly can be reliably avoided during handling. It is thus possible to provide an assembly, for example a circuit board with the corresponding components, as a modular unit with the L-shaped or U-shaped device base, which is easy to manufacture and assemble and safe to handle.

Furthermore, the side wall preferably has at least one fastening device with which the operating device can be fastened. In this way it is possible to use the operating device in a particularly versatile manner. It can therefore be used, for example, as a built-in version or as a built-on version.

Furthermore, the fastening devices are preferably spaced from the assembly when the latter is attached to the bottom part of the equipment floor, so that the operating device can be easily attached without damaging an assembly mounted thereon.

In addition, the base part has a grounding pin which, in a particularly preferred embodiment, is formed integrally with the base part. The grounding pin can thus be formed directly during the stamping and bending process for producing the device base, so that on the one hand work steps and on the other hand additional components and additional material can be saved. The grounding pin preferably extends away from the bottom part in the same direction as the side wall. The module can thus simply be placed on the base part via the grounding pin and is immediately protected in an imaginary space through base and side wall. The grounding contact is thus particularly easy to provide.

Furthermore, the bottom part and the side wall are integrally connected to one another via a step, with the shoulder of the step being aligned essentially parallel to the bottom part. At least one part of the assembly that requires particularly good heat dissipation lies flat on the shoulder of the step. It is thus possible to arrange the assembly in such a way that electronic components that require particularly good heat dissipation are located in the vicinity or directly above the stage. Good heat dissipation via the step is then ensured by the full-surface contact with the step. It is thus possible to dissipate the power loss very efficiently and in all conceivable device attachment options via the device base, without installing or installing additional cooling parts on or in the device base for this purpose.

For this purpose, the bottom of the device is particularly preferably made of a material with good thermal conductivity. This material is preferably aluminum, which can be processed particularly well, has high tensile strength and rigidity, and above all has a particularly high coefficient of thermal conductivity or a particularly high thermal conductivity A (λ=237 W/(m*K)). Furthermore, aluminum is particularly light, so that the weight of the operating device can also be kept as low as possible.

The operating device preferably also has a housing upper part. The upper part of the housing, together with the base of the device, completely encloses the assembly. In this way, the module is safely protected from the environment and cannot be damaged by external influences such as impacts or touch.

In a first embodiment, the upper part of the housing can be placed on the bottom of the device, so that the at least one fastening device is freely accessible from the outside. In a second embodiment, the housing top part completely encloses the device base and the assembly, with the housing top part preferably being formed from at least two parts, a cover part and a base part. It is therefore possible to place different upper housing parts as a "cover" on the modular unit consisting of the device base and assembly group, in order to obtain either a built-in version or a surface-mounted version of the operating device, for example. In a built-in version, the fastening devices on the side wall can therefore simply be used to fasten the operating device, for example to a wall, whereas in a surface-mounted version the side wall is arranged in the upper part of the housing and the at least one fastening device is used, for example, to fasten the base of the device in the Housing top can be used.

The upper part of the housing preferably has a tapering waist in order to further simplify the handling of the operating device.

In addition, the upper part of the housing has at least one strain relief on a side on which the side wall of the base part is not arranged. For this purpose, the strain relief is preferably arranged at an acute angle to the corresponding side of the upper part of the housing. If at least two strain reliefs are present, they are also arranged in a fan shape relative to one another, so that the strain reliefs are not arranged parallel but at an angle to one another in order to further facilitate the connection options for the cabling.

Furthermore, the upper part of the housing has a fastening device for fastening the base of the device, which is particularly preferably formed integrally in the base part of the upper part of the housing. It is thus possible to access the base part from above in order to fix it together with the circuit board on the base part.

In addition, the upper housing part has a fastening device for fastening the operating device, which is arranged on the opposite side of the upper housing part that has the strain relief and is particularly preferably integrally formed in the base part of the upper housing part. The floor screw connection can therefore take place on the back of the built-up version, preferably essentially in the middle on the back of the built-up version, while the contact with the strain reliefs is on the front side of the built-up version. There is therefore no hindrance to the cabling with the attachment, so that no additional insulation of the attachment means is required in relation to the respective cables.

Furthermore, the cover part is preferably formed in at least two parts from a cover part and a pivoting part, wherein the pivoting part is also preferably pivotably connected to the cover part and can be pivoted into defined, latched rotary positions. It is thus possible to pivot the pivoting part into defined, latched rotational positions, so that, for example, the pivoting part can be held in a defined open state when the cable is installed. This facilitates the assembly of the cables at a front portion of the control gear while at the same time Device bottom and assembly remain securely enclosed by the cover and the bottom part.

Furthermore, the strain relief has a strain relief pusher for blocking a cable, by means of which latching lugs in the base part can be pretensioned for locking the pivoting part with the base part. In this way, the cables can be blocked and the locking lugs can be pretensioned in one easy step. This ensures that the pivoting part is securely closed while the strain relief is also securely closed.

The cover part advantageously has a cooling plate. In this way, the heat dissipation can be further improved.

1-3 show a first exemplary embodiment of a device base 1 according to the invention for an operating device for lamps. The device base 1 preferably has a base part 2 and a side wall 3 . The device base 1, ie the base part 2 and the side wall 3 are preferably formed integrally with each other. The device base 1 can therefore be produced very easily and in a material-saving manner, for example from a single metal sheet in a stamping and forming process.

As 2 shows, the side wall 3 preferably protrudes from the base part 2 in such a way that the device base 1 is essentially L-shaped. An operating device designed in this way is particularly easy to handle, so that damage to the assembly can be reliably avoided. An assembly, such as a circuit board with the corresponding components, can thus be made available as a finished, modular unit with the L-shaped device base. This unit is easy to manufacture, assemble and handle safely.

In a particularly preferred embodiment, the device base 1 is made of a material with good thermal conductivity. This material is preferably aluminum or an aluminum alloy, which has high rigidity and tensile strength, is easy to process, is particularly light and, in particular, has good thermal conductivity. Aluminum is also particularly light, so that the weight of the control gear can be kept as low as possible. It is also conceivable that another material with good thermal conductivity is used for the base 1 of the device.

As in 2 as can be seen, the base part 2 and the side wall 3 are integrally connected to one another via a step 4 . A shoulder 5 of the step 4 is aligned essentially parallel to the base part 2 . It is thus possible for a subassembly, for example a printed circuit board, arranged on the device base 1 to rest at least partially flat on the shoulder 5 of the step 4 . Components of the assembly that require particularly good heat dissipation can thus preferably be arranged in the area near or above the step 4 or the step 5, so that the resulting heat loss can be efficiently transported away via this metallic step 4. This dissipation of heat loss is significantly improved by a device base 1 made of aluminum or another material with good thermal conductivity, since then the step 4, which is integrally formed with the device base 1, can also be made of this material simply, since the same stamping and Forming process produced, can be manufactured. In this way, the power loss can be dissipated very efficiently and also in all conceivable device attachment options via the device base 1 itself, without the need for additional cooling elements.

In order to ensure that a subassembly is fixed securely and stably on the device base 1 and in particular that the subassembly rests flat on the shoulder 5 of step 4, on at least one other side of the base part 2, on which the side wall 3 is not arranged, Assembly retaining walls 20, 21, 22, preferably also be formed integrally with the base part, the respective upper edge of which is at least partially at the same distance from the base part 2 as the upper edge of the shoulder 5 of the stage 4. It is thus possible to mount an assembly on the stage 4 and at least one assembly retaining wall 20, 21, 22 such that the assembly is positioned and securely supported by the stage 4 and the at least one assembly retaining wall 20, 21, 22. In this way, further means for arranging an assembly can be saved and the assembly can also be placed easily and securely on the base 1 of the device. The also integral design of this at least one assembly retaining wall 20, 21, 22 also saves work steps and other components that ensure carrying and positioning of the assembly, since it can also be formed in one stamping and forming process.

Furthermore, the side wall 3 preferably has at least one positioning element 40, 41. These positioning elements 40, 41 are also preferably integrally formed in the base 1 of the device. In a particularly preferred exemplary embodiment, at least the component holding wall 20 also has positioning elements 42, 43, which are preferably formed integrally. These positioning elements 40, 41, 42, 43 are designed in such a way that they can be bent at least towards the inside of the device base, in such a way that the positioning elements 40 to 43 contact an assembly arranged on the device base 1 from above in such a way that a constant clamping pressure is applied the assembly is exercised. In this way, the subassembly can be clamped between the subassembly retaining walls 20, 21, 22 or the step 4 and the positioning elements 40 to 43 and thus securely positioned, while additional components can be saved due to the integral design of the positioning elements 40 to 43.

How in particular 1 and 3 can be seen, the base part 2 preferably has at least one fastening device 23, 24 with which the operating device can be fastened. Furthermore, the fastening device 23 , 24 is preferably formed integrally with the base part 2 . In addition, the at least one fastening device 23, 24 is preferably spaced from the assembly in such a way that when the latter is arranged on the base part 2 of the device base 1, the operating device can be easily fastened via the fastening device 23, 24 without damaging the assembly .

Like the bottom part 2, the side wall 3 also has in a preferred embodiment at least one fastening device 30, 31, with which the control gear can be attached to the side. The fastening device 30, 31 of the side wall 3, like the fastening device 23, 24 of the base part 2, is preferably formed integrally with the device base 1.

Due to the integral design of at least one fastening device 23, 24, 30, 31 on the base part 2 and/or on the side wall 3, these can also be formed in one stamping and forming process and at the same time ensure that the operating device can be used in a variety of ways, for example as a built-in version or as a build-up version, as will be explained in more detail below.

In a particularly preferred embodiment, the base part 2 also has a grounding pin 6 which is also preferably formed integrally with the base 1 of the device. For this purpose, the grounding pin 6 is preferably punched out of the device base 1 and bent accordingly so that it protrudes from the device base 1 in such a way that the assembly can be arranged on the grounding pin 6 and brought into contact with it in a particularly simple manner. In order to connect the grounding pin to the assembly when an assembly is placed on the device base 1 , the grounding pin 6 preferably extends away from the base part 2 in the same direction as the side wall 3 extends away from the base part 2 . Consequently, the grounding pin 6 can also be formed integrally with the base of the device in one stamping and forming process. As a result, the grounding pin 6 does not have to be additionally riveted or pressed onto the base of the device or additionally attached in any other way.

The design of the grounding pin 6 according to the invention also makes it possible to bring the assembly into contact with this grounding pin 6 very simply by means of a plug-in movement. For this purpose, the grounding pin 6 is preferably designed as an insulation displacement contact, so that a grounding contact with the assembly can be established simply and safely by simply plugging the assembly onto the grounding pin 6 of the device base 1 . Furthermore, when the module is arranged on the grounding pin 6, it is in an imaginary space spanned by the base part 2 and side wall 3 of the device base 1 and is therefore very advantageously protected against direct mechanical influences during further handling and also offers good accessibility to the assembly.

All of the aforementioned elements are therefore preferably formed integrally with the base of the device, as a result of which work steps, components, materials and costs in the manufacture and assembly of the operating device can be saved. The use of aluminum in the device base also combines the properties that it can be easily processed, for example in a stamping and bending process, and that it has high rigidity, tensile strength and, above all, high thermal conductivity.

4 shows, for example, an aluminum sheet BE after the stamping process for producing a device base according to the invention in accordance with the above-mentioned exemplary embodiment. After the stamping process, the complete device base 1 can be produced directly from this aluminum sheet BE in a further forming process, without using additional components.

How in particular 1 can be seen, the side wall 3 also has holding elements 32, 33, which are preferably also formed integrally with the base 1 of the device. By means of these holding elements 32, 33 it is possible to attach a housing upper part 100 (cf. 5 ) to be fixed on the bottom of the device.

The holding elements 32, 33 are preferably arranged on a partial area 3a of the side wall 3, which is offset essentially parallel to the side wall 3 towards the inside of the appliance base. Advantageously, the partial area 3a is formed from the side wall 3 in a forming or stamping and bending process, and its upper edge preferably extends up to a height of the upper edge of the side wall 3. Furthermore, the partial area 3a is advantageously at least at its upper edge of the Section 3a opposite side with the side wall 3 integrally connected. The connection of the side wall 3 with its portion 3a is preferably designed in such a way that the portion 3a is designed to be resilient relative to the side wall 3, so that it can be bent towards the inside of the device on the side opposite the connection point. In this way, as will be explained in more detail below, the upper housing part 100 can simply be placed on the base of the device, it being securely fixed, and it can also be easily detached again.

In a particularly preferred embodiment, in addition to the side wall 3, at least one of the component holding walls 20, 21, 22 also has at least one holding element 34, 35. These holding elements 32 to 35 are preferably all formed integrally with the base 1 of the device. Secure fixing of the upper housing part 100 can thus be ensured due to the holding elements 32 to 35 arranged in a distributed manner, with the holding elements being able to be produced simply in one stamping and forming process.

A first embodiment of a housing upper part 100 according to the invention will now be described below.

5 shows a housing top part 100. The housing top part 100 preferably has a cover part 101 and also preferably one or more side parts 102, 103, 104, 105 extending away from the cover part 101 in one direction. The cover part 101 and the side walls 102 to 105 are preferably formed integrally with one another and particularly preferably made of metal, for example aluminum. However, the invention is not limited to this, but they can also be made of any other material.

The upper housing part 100 is constructed in such a way that when assembled with the device base 1 it forms a substantially closed space in which the assembly is arranged. In this way, the upper housing part 100 completely encloses the assembly together with the device base 1 . The assembly is thus safely protected from the environment and cannot be damaged by external (mechanical) influences such as impacts or touch.

The upper housing part 100 can have at least one, preferably two or more, retaining elements 110, 111 on at least one side wall 102, which correspond to the retaining elements 32, 33 formed in the device base 1 when the upper housing part 100 is in the assembled state. The retaining elements 110, 111 are also preferably formed integrally with the housing upper part 100 and are also preferably formed as hooking or latching elements. It is thus possible to ensure that the operating device is locked, while no additional locking parts are required. In addition, when using interlocking or latching elements, the operating device can also be closed quickly and securely and opened easily.

The side wall 102 is also preferably designed in such a way that it corresponds to the partial area 3a of the side wall 3 in such a way that an essentially flat surface is formed between the side walls 3, 102, i.e. the side wall 102 extends flatly from the outside behind the partial area 3a, see above that the holding elements 32, 33, 110, 111 correspond to one another. This prevents the upper housing part 100 from being accidentally opened from the base 1 of the device. Due to the preferably resilient design of the partial area 3a, it can easily be bent towards the inside of the device base, for example using a tool, so that the latched holding elements 32, 33, 110, 111 can be released from one another and the upper housing part 100 can be easily removed from the device base.

In addition, the upper housing part 100 preferably also has at least one holding element 112, 113 on one of the other side walls 103-105, which in the assembled state corresponds to the corresponding holding element 34, 35 of the device base 1. These holding elements 112, 113 are preferably formed integrally with the housing upper part 100 and can also be formed as hooking or latching elements. This ensures that the control gear is locked even better.

The overlap between the upper housing part 100 and the device base 1 in the assembled state is preferably very small in order to create a closed space and thus accommodate the assembly in a protected manner, but with as little material expenditure as possible. In a particularly preferred embodiment, the device base 1 overlaps with the upper housing part 100 in the assembled state only in the area of the retaining elements 32-35 and 110-113, in order to ensure the minimum possible use of material. Where there is no overlap, the sides of the device base 1 and the housing upper part 100 are preferably flush with one another.

At least one side wall 104 of the housing upper part 100 preferably has a recess for connection terminals A arranged on the assembly (cf. 8th ) so that they are accessible from the outside even when assembled. The side wall 104 is designed in such a way that it also ends flush with the connection terminals A and is designed as a cover in the areas where no connection terminal is arranged, in order to provide a securely covered and protected assembly with minimal material expenditure.

The upper housing part 100 is shaped in such a way that all fastening devices 23, 24, 32, 33 of the device base 1 are freely accessible from the outside when the housing upper part 100 is placed on the device base 1. By using a housing upper part 100 according to the first embodiment, an operating device is thus obtained as a built-in version, which can be fastened, for example, to the bottom, to the ceiling or to the side, for example to a wall.

All elements of the upper housing part 100 are thus also preferably formed integrally from a single part. 7 shows, for example, a metal sheet BZ' after the punching process Process for manufacturing a housing upper part 100 according to the first embodiment. In this way, further work steps, components, materials and costs can be saved in the manufacture and assembly of the operating device.

In the 9 until 14 an operating device according to the invention is shown as a built-in version according to a second exemplary embodiment. Features 1' to 6', 21' to 24', 30' to 33', 40', 41', 101', 102', 104', 105', 110', 111' and A' correspond substantially exactly the features 1 to 6, 21 to 24, 30 to 33, 40, 41, 101, 102, 104, 105, 110, 111 and A. With regard to these features, reference is therefore made to the above description. In the following, therefore, only the differences compared to the aforementioned embodiments will be described.

Like the one in particular 9 and 10 As can be seen, an essential difference between the device base 1' and the device base 1 is that, instead of the component retaining wall 20, there is a second side wall 20' on the side of the first side wall 3' opposite the base part 2', i.e. also opposite the step 4 ', so that the device base 1' is essentially U-shaped. In this way, an assembly B' (cf. 13 ) is protected even better against damage and handling is further improved, with the above-mentioned advantages of the device base 1, 1' being fully retained.

The second side wall 20' is preferably formed essentially as a mirror image of the first side wall 3'. The second side wall 20' therefore advantageously also has holding elements 34', 35' (like the holding elements 32', 33'), a partial area 20a' of the side wall 20' (like the partial area 3a') and positioning elements 42', 43'. In addition, it is also conceivable that the second side wall 20' has corresponding fastening devices, such as the fastening devices 30', 31', in order to be able to be fastened on both sides and to further increase the possible uses of the operating device.

At least one assembly holding element 50', 51' is preferably arranged on the side of the base part 2' opposite the step 4', ie on the side of the base part 2' facing the second side wall 20'. The upper edge of the assembly holding element 50', 51' has the same distance from the bottom part 2' as the upper edge of the shoulder 5' of the step 4'. In this way, an assembly B' can be positioned and securely supported on the stage 4', the assembly holding walls 21', 22' and the assembly holding members 50', 51' and also securely clamped by the positioning members 40' to 43'.

The assembly holding elements 50', 51' are preferably formed integrally with the device base 1', particularly preferably stamped out of the base part 2' and bent upwards, as is the grounding pin 6'. In a particularly preferred manner, the assembly holding elements 50', 51' are arranged to and in front of the side wall 20' in the base part 2' such that after the positioning elements 42', 43' are bent down when the assembly B' is arranged on the appliance base 1', the positioning elements 42 ', 43' form a clamping point for clamping the assembly B' with the upper edge of the assembly holding elements 50', 51'.

However, it is also conceivable that the bottom part 2' and the side wall 20' are also integrally connected to one another via a step (not shown), the step of this second step being aligned essentially parallel to the bottom part 2'. This stage is preferably designed like stage 4'. In this case, full-area contact of an assembly B′ arranged on the first stage 4′ and the second stage is increased and improved heat dissipation is thus possible in several areas of the assembly B′. Furthermore, the second stage also serves as a support for positioning the assembly B', so that the assembly holding members 50', 51' are no longer needed in this case and can be omitted.

Corresponding to the U-shaped configuration of the device base 1', the upper housing part 100' is also adapted in relation to the upper housing part 100, as can be seen in particular from FIGS 11 and 12 evident. The essentially only difference is that the side wall 103' is now designed analogously to the side wall 102', and thus also the holding elements 112', 113' are designed analogously to the holding elements 110', 111', so that the holding elements 110' to 113 'Surely correspond to the holding elements 32' to 35' of the device base, the connection is thus formed essentially identically on both side walls 102', 103'. At this point, reference is made to corresponding descriptions of the upper housing part 100 .

• In einem ersten Schritt wird der Geräteboden 1, 1' mit einer Isolationsfolie F' versehen, um eine eventuelle elektrische Verbindung zwischen Baugruppe B' und Gehäuse bzw. Geräteboden 1, 1' zu vermeiden. Sodann wird ein sogenannter Gap-Filler auf den Absatz 5, 5' der Stufe 4, 4' aufgebracht. Im Folgenden wird die Baugruppe B' derart an dem Geräteboden 1, 1' angebracht, dass der Erdungspin 6, 6' in Kontakt mit einem Erdungskontakt der Baugruppe B' gebracht wird, und wenigstens ein Teil der Baugruppe B' flächig auf dem Absatz 5, 5' der Stufe 4, 4' des Gerätebodens 1, 1' aufliegt. Weist der Geräteboden 1' wenigstens zwei oben beschriebene Stufen 4' auf, so liegt die Baugruppe B' flächig auf beiden Absätzen 5' der Stufen 4' des Gerätebodens 1' auf. Vorzugsweise liegt die Baugruppe B' ebenso auf wenigstens einem Teil der wenigstens einen weiteren Baugruppenhaltewand 20, 21, 22 bzw. 21', 22' sowie dem Baugruppenhalteelement 50', 51' auf und wird somit sicher positioniert und gestützt. Zur sicheren Positionierung und Fixierung der Baugruppe ist es ferner möglich, die Positionierelemente 40 bis 43 bzw. 40' bis 43' in Klemmposition zu bringen, also derart umzubiegen, dass sie in Klemmkontakt mit der Baugruppe B' gebracht sind. In einem dritten Schritt wird vorzugsweise ein Gap-Pad oder Gap-Filler entsprechend auf die bisher zusammengebaute Anordnung aufgebracht. In-, einem letzten Schritt wird das Gehäuseoberteil 100, 100' auf den Geräteboden 1, 1' aufgesteckt, wobei die jeweils miteinander korrespondierenden Halteelemente 32 bis 35 und 110 bis 113 bzw. 32' bis 35' und 110' bis 113' miteinander verrasten. Aufgrund der erfindungsgemäßen Ausgestaltungsform sind die Befestigungsvorrichtungen 23, 23', 24, 24', 30, 30', 31, 31' im zusammengesetzten Zustand, wie bspw. in 8 gezeigt, von außen frei zugänglich, so dass das fertig zusammengebaute Betriebsgerät für Leuchtmittel BEV, von welchem die Baugruppe B' sicher umschlossen ist, einfach an den gewünschten Ort bodenseitig oder seitlich oder auch deckenseitig angebracht werden kann.

The steps for assembling an operating device as a built-in version BEV (cf. 8th , 13 and 14 ) described:

• In a first step, the device base 1, 1' is provided with an insulating film F' in order to prevent any electrical connection between the assembly B' and the housing or device base 1, 1'. A so-called gap filler is then applied to the step 5, 5' of the step 4, 4'. The following is the assembly B' is attached to the device base 1, 1' in such a way that the grounding pin 6, 6' is brought into contact with a grounding contact of the assembly B', and at least part of the assembly B' is flat on the shoulder 5, 5' of the stage 4 , 4' of the device base 1, 1' rests. If the device base 1' has at least two steps 4' described above, the assembly B' lies flat on both shoulders 5' of the steps 4' of the device base 1'. The assembly B' preferably also rests on at least part of the at least one further assembly retaining wall 20, 21, 22 or 21', 22' and the assembly retaining element 50', 51' and is thus securely positioned and supported. For safe positioning and fixing of the subassembly, it is also possible to bring the positioning elements 40 to 43 or 40' to 43' into the clamping position, ie to bend them in such a way that they are brought into clamping contact with the subassembly B'. In a third step, a gap pad or gap filler is preferably applied accordingly to the previously assembled arrangement. In a final step, the upper housing part 100, 100' is placed on the device base 1, 1', with the corresponding holding elements 32 to 35 and 110 to 113 or 32' to 35' and 110' to 113' locking together . Due to the embodiment according to the invention, the fastening devices 23, 23', 24, 24', 30, 30', 31, 31' are in the assembled state, as for example in 8th shown, freely accessible from the outside, so that the fully assembled operating device for lamps BEV, of which the assembly B 'is securely enclosed, can be easily attached to the desired location on the floor or side or ceiling side.

According to a further embodiment, it is also conceivable to design the upper housing part 200, 1200 in such a way that it completely encloses the device base 1, 1' and the assembly B, B'. 15 until 24 show two preferred embodiments of such an operating device BAV, BAV' according to the invention, which are particularly suitable as a built-on version.

15 shows a first and 16 a second embodiment of an operating device as an add-on version BAV, BAV'. The upper housing part 200, 1200 is preferably made of metal, but can also be made of any other material, for example plastic. In order to improve the handling of the housing upper part 200, 1200, this can have a tapering waist. In the region of the waist, the housing upper part 200, 1200 is also preferably formed with an anti-slip surface, for example an integrally formed roughened surface.

As 15 and 16 It can also be seen that the upper housing part 200, 1200 is preferably in two parts, consisting of a base part 220, 1220 and a cover part 230, 1230. However, the upper housing part 200, 1200 can also be designed in one piece or in several pieces.

17 shows a base part 1220 according to the invention, which is used in the second preferred embodiment of the operating device BAV'; however, it can also be used in the operating device BAV according to the first embodiment. Preferably, the base part 220, 1220 and the cover part 230, 1230 are connected with a hinge or a captive device, which are particularly preferably formed integrally with the housing upper part 200, 1200.

How in particular 17 and 23 As can be seen, the upper housing part 200, 1200 has at least one retaining element 1210, 1211 in the base part 220, 1220 and cover part 230, 1230, which correspond to one another in the closed state of the upper housing part 200, 1200 in order to hold the upper housing part 200, 1200 by latching them To lock holding elements 1210, 1211 together securely. If a hinge is present, the holding elements 1210, 1211 of the upper housing part 200, 1200 are preferably arranged at least on the side opposite the hinge.

In a preferred embodiment, the upper housing part 200, 1200 also has a sealing element (not shown) between the base part 220, 1220 and the cover part 230, 1230, in order to reliably prevent the ingress of dirt or moisture, for example.

It is also conceivable to provide the upper housing part 200, 1200 with at least one strain relief 201, 1201 on one side 202, 1202, also referred to below as the end face, of the upper housing part 200, 1200 on which the side wall 3, 3', 20' is not located. of the device base 1, 1' is arranged when this is inserted into the housing upper part 200, 1200. The strain relief 201, 1201 is preferably formed integrally with the housing upper part 200, 1200, so that no additional parts are required for this either.

It is particularly preferable how 17 shows, the strain relief 201, 1201 of the housing upper part 200, 1200 is arranged in the base part 220, 1220, particularly preferably formed integrally with this.

18 shows a section of the in 17 shown base part 1220, in which the strain relief 201, 1201, in the example shown three strain relief 201, 1201, is or are arranged. The strain relief 201, 1201 preferably has two tongues 1250 lying opposite one another and to the left and right of a strain relief channel Z of the upper housing part 200, 1200, as viewed in the direction of insertion. The tongue 1250 is preferably designed in the manner of a ratchet, in that it particularly preferably has a large number of teeth 1251 arranged one above the other. These teeth 1251 are preferably directed away from the strain relief channel Z with respect to the latter. Furthermore, the strain relief 201, 1201 preferably has a retaining edge 1252 that extends between the tongues 1250, preferably in a lower region of the strain relief channel Z, which prevents the cable from slipping out or being pulled out, ie blocks it.

In order to achieve jamming or blocking of an inserted cable, the strain relief 201, 1201 also preferably has a strain relief pusher 1260, which is advantageously designed as a separate part or else integrally with the upper housing part 200, 1200. 19 shows a view like the one in 18 , but with strain relief pushers 1260 inserted. The strain relief pusher 1260 preferably has guide rails 1261 on two opposite sides, into which the tongues 1250 can be inserted. The strain relief pusher 1260 can thus be pushed onto the tongues 1250 arranged to the left and right of the strain relief channel Z in such a way that it is arranged on a side opposite the holding edge 1252 with respect to the strain relief channel Z.

The side of the strain relief pusher 1260 that faces the holding edge 1252 can also be designed in such a way that it has at least one holding element for blocking a cable K.

So that a sufficient clamping force of the strain relief 1201 can be ensured, the strain relief pusher 1260 has a clamping element 1262 within the guide rails 1261, or on the side of the guide rails 1261 facing the teeth 1251, which is preferably formed integrally with the strain relief pusher 1260 and with the teeth 1251 corresponds (cf. also 22 ). The clamping element 1262 is preferably mounted or designed to be spring-loaded, so that it hooks onto the teeth 1251 with a sufficient clamping force. Since numerous teeth 1251 are preferably formed in the tongues 1250, the strain relief pusher 1260 also has a corresponding number of latching positions, so that reliable clamping or blocking of the cable is ensured.

It should be noted that the strain reliefs 201, 1201 are aligned parallel to one another in the examples shown. In a particularly preferred embodiment, the strain relief 201, 1201 can also be arranged at an acute angle to the end face 202, 1202 of the upper housing part 200, 1200, and if there are at least two strain reliefs 201, 1201, these can also be arranged in a fan shape relative to one another. In this way, the accessibility of the strain reliefs 201, 1201 and the possibility of connecting them can be facilitated. However, it is also possible to arrange the strain reliefs 201, 1201, as shown in the figures, parallel or in a different orientation to one another.

Particularly in the case of HID EVGs (electronic ballast for high-pressure gas discharge lamps), three strain reliefs 201, 1201 are particularly preferably used because of their high ignition voltage. In the case of simpler variants, for example FL EVGs (electronic ballast for fluorescent lamps), fewer, and in the case of more complex variants, more than three strain reliefs 201, 1201 can also be provided.

According to a first embodiment, as in 15 shown, the lid portion 230 is integrally formed in one piece. However, it is also conceivable that the cover part 1230 is designed in several parts, preferably in two parts, as in 20 shown.

20 shows an exploded drawing of a housing upper part 1200 according to the second embodiment. The cover part 1230 of the housing upper part 1200 is preferably designed in two parts and has a cover part 1231, which completely encloses the device base 1, 1' and the assembly B, B' with the base part 1220, and a swivel part 1232, which can be swiveled with the cover part 1231 is connected and is arranged on the end face 1202 of the housing upper part 1200, ie in an open state the strain relief(s) 1201 is exposed. In this way, it is easily possible to access the strain relief 1201, while the device base 1, 1 'and assembly B, B' continue to be securely in the housing top part 1200, ie between the base part 1220 and cover part 1231, enclosed. It should be noted that the cover part 1231 can also consist of more than two parts, ie it can have several pivoting parts, for example, in order to be able to access different areas of the operating device BAV' individually.

The pivoting part 1232 is preferably connected by means of a hinge 1233 (cf. 21 ) to the Cover part 1231 of the cover part 1230 is pivotably and preferably detachably attached. The hinge 1233 is also preferably formed integrally with the cover part 1231 and is advantageously designed in such a way that the pivoting part 1232 can assume defined rotational positions. This is preferably done by gradual locking into different pivot positions, ie into defined, locked rotational positions. It is thus possible to keep the pivoting part 1232 of the cover part 1230 in a defined open state, for example when installing the cables, in order to facilitate the installation.

22 12 shows an underside, ie a side of the pivoting part 1232 directed in the closed state into the interior of the upper housing part 1200. Holders 1234, into which the strain relief pushers 1260 can be snapped, preferably extend from the underside. In this way, the separate strain relief pushers 1260 are held securely on the pivoting part 1232, particularly during transport, and cannot be lost. The holders 1234 thus serve to prevent the strain relief pushers 1260 from being lost, especially during transport of the pivoting part 1232. To use the strain relief pushers 1260, the hook or holder 1234 is simply released by the fitter and placed on the tongues 1250 accordingly.

When the strain relief pushers 1260 are pushed onto the tongues 1250 after the cables have been inserted into the strain relief channels Z in order to securely block the cables K, latching lugs 1253 are biased outwards at the same time as the strain relief pushers 1260 are pressed down. The latching lugs 1253 are preferably formed integrally and resiliently with the base part 1220 (cf. 18 and 19 ). When the strain relief pusher 1260 is depressed, part of the guide rail 1261 slides behind the locking lug 1253. This is preferably designed in such a way that at least one upper end of the locking lug 1253 tapers upwards. The strain relief pusher 1260 therefore slides along the locking lug 1253 and pushes it outwards due to the tapering tip, so that it is pretensioned.

With reference to 21 the pivoting part 1232 has latching elements, preferably latching recesses 1235. If base part 1220 and cover part 1231 are closed and enclose device base 1, 1′ and subassembly B, B′, and if cable K is also inserted, strain relief pusher 1260 is inserted and latching lugs 1253 are pretensioned, pivoting part 1232 can be pivoted into a closed position and thus the end face 1202 of the upper housing part 1200 can also be closed. The latching lugs 1253 engage in the latching recesses 1236 in the pivoting part 1232. In this way, the pivoting part 1232 is also securely closed. Depressing the strain relief pusher 1260 activates the latching lugs 1253 for the preferred snap connection, so to speak.

23 shows a cover part 1231 according to the invention of the operating device BAV' according to the second embodiment. This already has above-mentioned retaining elements 1211, which correspond to the retaining elements 1210 of the base part 1220 in order to securely connect these two parts to one another in order to also securely enclose the device base 1, 1' and assembly group B, B'.

Furthermore, it is also possible for the cover part 203, 1203 to have a cooling plate KB, which is preferably arranged on the underside of the cover part 230, 1230 or the cover part 1231. The cooling plate KB can be introduced or attached, for example, by overmolding or by snapping into correspondingly provided latching elements. In this way, the heat dissipation of the operating device BAV, BAV' can be further improved.

In order to securely fasten the device base 1, 1' in the housing top part 200, 1200, the housing top part 200, 1200 also has a fastening device, preferably in its bottom part 220, 1220, which can be connected to at least one of the fastening devices 23, 23', 24, 24'. , 30, 30', 31, 31' of the device base 1, 1' when installed. In this way, a simple fastening is provided integrally with the components, which is easily accessible and reduces the likelihood of damage to the operating device due to the inventive arrangement of these fastening devices 23, 23', 24, 24', 30, 30', 31, 31 ' minimized.

In order to also improve and simplify the attachment of the operating device BAV, BAV' to a floor etc. and the connection of the cabling K of the device, a fastening device 1240 of the upper housing part 200, 1200 is provided on a side 202, 1202 with the strain relief 201, 1201 opposite side 203, 1203, hereinafter also referred to as the rear, as is also the case in particular in 24 is shown. Additional insulation of the fastening elements from the cabling K can thus be saved, since the fastening device 1240 is arranged on the back 203, 1203 of the operating device or the upper housing part 200, 1200 of the surface-mounted version, whereas the contact with the strain reliefs 201, 1201 is on the end face 202, 1202 of this construction version is present. Particularly preferably, the fastening device of the upper housing part 200, 1200 is essentially Chen centrally located on the back 203, 1203, so that the accessibility of this is improved.

The fastening devices of the housing upper part 200, 1200 are preferably arranged in the base part 220, 1220, particularly preferably formed integrally with this. Thus, the device base assembly module can be easily inserted into the base part 220, 1220 from above and attached to it. The base part 220 can then be securely closed with the cover part 230, 1230 and the operating device BAV, BAV' can be installed.

With reference to 15 and 24 the cover part 203, 1203 or the cover part 1231 and the base part 220, 1220 preferably each have a mutually aligned recess 236, 1226, 1236 on the rear side 203, 1203 of the housing upper part 200, 1200 in order to improve the accessibility of the preferably in the base part 220, 1220 trained fastening device 1240 to ensure.

The following describes how an operating device BAV, BAV' according to the present invention is assembled as a built-up version.

The equipment base 1, 1' is fitted with an assembly B, B' in the same way as in the aforementioned embodiments. The module consisting of device base 1, 1' and subassembly B, B' is then inserted as a whole into the housing top part 200 and with the housing top part 200 via its fastening device and at least one of the fastening devices 23, 23', 24, 24', 30, 30 ', 31, 31' of the device base 1, 1' attached. The assembled operating device consisting of the upper housing part 200, which completely encloses the device base 1, 1' with the subassembly B, B', can now be attached as a whole as a surface-mounted version at the appropriate location.

In particular in an operating device according to the second embodiment, the wiring K can be easily connected at any time, even after the cover part 1231 and the base part 1220 have been closed with the device base 1, 1′ with assembly B, B′ enclosed. This is possible because due to the open pivot part 1232, which is preferably held in a defined position, both the strain relief(s) 1201 and the connection terminals A, A' are still freely accessible. The cables K can be connected to the connection terminals A, A′, inserted into the strain relief channel Z and blocked by means of the strain relief push-button 1260 . The pivoting part 1232 can then also be closed, with the latching lugs 1253 prestressed by the inserted strain relief pushers 1260 latching into the latching elements 1235.

It is therefore possible, with one and the same device base 1, 1', which is designed integrally, i.e. in one piece and has particularly good thermal conductivity and also has an integrally designed grounding pin 6, 6', by using different housing top parts 100, 100', 200 different control gear versions BEV, BEV', BAV, BAV'. For example, operating devices can be obtained as a built-in version or as a built-on version with the same device base 1, 1' or the same modular unit.

The invention is not limited to the limitations mentioned above. All conceivable configurations of the mentioned embodiment are covered by this application. For example, the respective side walls can be of different heights, the shoulder of the step can have different surfaces, the fastening and holding devices can be in the form of all known fastening forms. Furthermore, the fastening device of the built-in version can also be arranged on the cover side. Furthermore, the built-in version can also have the features, such as a strain relief, which are described and illustrated in connection with the built-on version. The housing described according to the invention is preferably used for ballasts for HID lamps (High-Intensity Discharge Lamp=high-pressure gas discharge lamp). In particular, this technology can also be transferred to fluorescent lamps, etc.
