Description

The invention relates to an operating device for lighting means 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 that is required in gas discharge lamps and fluorescent lamps, in particular for current limitation.

Numerous embodiments for housings of electronic operating devices are known from the prior art. For example, in the document WO 01/31980 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. To dissipate the heat loss, the base plate has a plate-shaped, metal cooling element, which is introduced into the base plate during the course of the injection molding process to produce the base plate. A floor screw connection of the version shown in this publication for a ballast is provided on the respective end faces on which the strain reliefs for the cabling of the device are also located. This can lead to problems with the screw connection, as this is hindered by the wiring of the device. Further measures may therefore be necessary to ensure adequate insulation of the fastening elements from the cables running over them.

From the EP 0 798 951 A2 a converter housing, in particular for an electronic converter for halogen lamps, is known.

The converter housing has a housing base body for receiving electronic components and a terminating element with a cable support for supporting at least one electrical connection cable. The housing base body and the closing element are arranged vertically to one another. At the end opposite the closing element, the housing base body also has an end surface that is rounded towards its underside.

In the pamphlet DE 202 15 425 U1 a housing for a printed circuit board is shown, the housing having 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 housing part have areas which are angled outwardly at an angle near the bottom, on which a printed circuit board can be arranged at a defined distance from the housing bottom. Fastening tabs are also formed in the housing cover, by means of which the housing can only be fastened to a base on the bottom side 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 structure and versatile in use.

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

According to 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. An upper part of the housing completely encloses the assembly. The upper housing part has at least one strain relief on one side of the upper housing part. The upper housing part is formed in at least two parts from a base part and a cover part, the cover part being formed from a cover part and a pivot part. The strain relief has a strain relief lever designed as a separate part for jamming or blocking an inserted cable. Holders extend from an underside of the pivoting part that is directed into the interior of the upper housing part in the closed state, the strain relief lever being able to be snapped into the holder.

The device base preferably has a base part and a side wall which are formed integrally with one another. The side wall preferably protrudes from the base part in such a way that the device base is L-shaped.

Alternatively, the device base preferably has a base part and at least two side walls which are formed integrally with one another. The side walls preferably protrude from the base part in such a way that the device base is U-shaped.

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

Furthermore, the assembly is advantageously attached to the base part of the device base.

The bottom 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.

Particularly advantageously, the bottom part and the side wall are integrally connected to one another via a step, the shoulder of which is oriented essentially parallel to the bottom part. A part of the assembly is preferably flat on the shoulder of the step.

The device base is advantageously made from a material that conducts heat well, preferably aluminum.

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

In one 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 further 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 relative to one another.

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

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

The cover part is preferably formed at least in two parts from a cover part and a pivot part, wherein the pivot part is furthermore preferably pivotably connected to the cover part and can be pivoted into defined, latched rotational positions.

The strain relief preferably has a strain relief lever for blocking a cable, by means of which latching lugs in the base part can simultaneously be pretensioned for locking the pivoting part to the base part.

The cover part advantageously has a cooling plate.

The device base of the operating device for lighting means according to one embodiment preferably 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 lighting means according to another embodiment preferably 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 device base can thus be produced very easily 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 bottom 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 use.

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 thus be used, for example, as a built-in version or as a surface-mounted version.

Furthermore, the fastening devices are preferably at a distance from the assembly when the latter is attached to the base part of the device base, so that the operating device can be fastened in a simple manner without damaging an assembly that is attached to it.

In addition, the bottom part has a grounding pin which, in a particularly preferred embodiment, is formed integrally with the bottom part. The earthing pin can thus be used directly during the punching and bending process for the production of the Device bottom are formed with, 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 base part in the same direction as the side wall. The assembly can thus simply be placed on the bottom part via the earthing pin and is immediately protected in an imaginary space spanned by the bottom part and side wall. The ground contact is therefore particularly easy to provide.

Furthermore, the bottom part and the side wall are preferably integrally connected to one another via a step, the shoulder of the step being oriented essentially parallel to the bottom part. Particularly preferably, at least part of the assembly rests 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 near or directly above the step. The full-surface contact with the step then ensures good heat dissipation via the step. It is thus possible to dissipate the power loss very efficiently and in all conceivable device fastening options via the device base without attaching or introducing additional cooling parts on or in the device base.

For this purpose, the device base is particularly preferably made of a material that conducts heat well. This material is preferably aluminum, which is particularly easy to process, has high tensile strength and rigidity, and above all has a particularly high coefficient of thermal conductivity or a particularly high thermal conductivity λ (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.

As described, the operating device has the upper part of the housing. The upper part of the housing encloses the assembly, preferably together with the device base. In this way, the assembly is reliably protected from the environment and cannot be damaged by external influences such as impacts or contact.

In one embodiment, the upper housing part 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 further embodiment, the upper housing part completely encloses the device base and the assembly, the upper housing part preferably being formed from at least two parts, a cover part and a base part. It is thus possible to place different upper parts of the housing as "covers" on the modular unit consisting of the device base and assembly in order to obtain, for example, either a built-in version or a built-in version of the operating device. In a built-in version, the fastening devices of the side wall can therefore simply be used to fasten the operating device, for example to a wall, whereas in a built-in version the side wall is arranged in the upper part of the housing and the at least one fastening device, for example, for fastening the device base in the Housing upper part 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 one side on which the side wall of the bottom part is not arranged. For this purpose, the strain relief is preferably arranged at an acute angle to the corresponding side of the upper housing part.

If there are at least two strain reliefs, these are preferably also arranged in a fan shape to one another, so that the strain reliefs are not parallel, but rather are arranged at an angle to one another in order to further facilitate the connection options for the cabling.

Furthermore, the upper part of the housing preferably has a fastening device for fastening the bottom of the device, which is particularly preferably integrally formed in the base part of the upper part of the housing. Access to the base part from above is thus possible 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 a side of the upper housing part opposite the side having the strain relief and is particularly preferably integrally formed in the bottom part of the upper housing part. The floor screw connection can therefore be made on the rear of the surface-mounted version, preferably essentially in the center of the rear of the surface-mounted version, while the contact with the strain relief is present on the front side of the surface-mounted version. There is therefore no obstruction of the cabling with the fastening, so that no additional insulation of the fastening means with respect to the respective cables is required.

Furthermore, the cover part is preferably formed at least in two parts from a cover part and a pivot part, the Pivoting part is also preferably pivotably connected to the cover part, and is pivotable into defined, latched rotational positions. It is thus possible to pivot the pivoting part into defined, locked-in rotational positions, so that, for example, the pivoting part can be kept in a defined open state when the cables are installed. This facilitates the installation of the cables on a front area of the operating device, while at the same time the device base and the assembly remain securely enclosed by the cover part and the base part.

Furthermore, the strain relief has a strain relief lever for blocking a cable, by means of which latching lugs in the base part for locking the pivoting part to the base part can be prestressed, preferably at the same time. In this way, both the cables and the locking lugs can be pretensioned in one simple step. This ensures that the swivel 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 improved even further.

1-3 show a first embodiment of a device base according to the invention 1 for a control gear for lamps. The device base 1 preferably has a bottom part 2 and a side wall 3 on. The device base 1 , so the bottom part 2 and the side wall 3 , are preferably formed integrally with one another. The device base 1 can therefore be produced very easily and in a material-saving manner, for example from a single sheet in a punching and forming process.

As 2 shows the side wall is standing 3 preferably so from the bottom part 2 from that the device base 1 is substantially L-shaped. An operating device configured in this way can be handled particularly well, 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 safe to use.

In a particularly preferred embodiment, the device base is 1 made of a material that conducts heat well. This material is preferably aluminum or an aluminum alloy, which has a high level of 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 operating device can also be kept as low as possible. It is also conceivable that a different, highly thermally conductive material for the device base 1 is used.

As in 2 can be seen are the bottom part 2 and the side wall 3 preferably over one stage 4th integrally connected to each other. One paragraph 5 the stage 4th is essentially parallel to the bottom part 2 aligned. It is therefore possible that one on the bottom of the device 1 arranged assembly, for example a circuit board, at least partially flat on the shoulder 5 the stage 4th rests. Components of the assembly that require particularly good heat dissipation can thus preferably be in the area near or above the step 4th or the paragraph 5 be arranged so that the resulting heat loss over this metallic step 4th can be removed efficiently. This dissipated heat dissipation is achieved by a device base made of aluminum or another material that conducts heat well 1 still significantly improved, because then the level 4th which is integral with the device base 1 is designed, made of just this material, since it can be manufactured in the same stamping and forming process. In this way, the power loss can be very efficient and also in all conceivable device mounting options via the device base 1 can be dissipated without the need for additional cooling elements.

To ensure that an assembly is securely and stably fixed to the device base 1 and in particular a flat resting of the assembly on the shoulder 5 the stage 4th to ensure, can also on at least one other side of the bottom part 2 on which not the side wall 3 is arranged, assembly retaining walls 20th , 21st , 22nd , preferably also be integrally formed with the bottom part, the respective upper edge of which is at least partially the same distance from the bottom part 2 like the top of the paragraph 5 the stage 4th . It is thus possible to have an assembly on the stage 4th and at least one assembly retaining wall 20th , 21st , 22nd to be arranged so that the assembly from the step 4th and the at least one assembly retaining wall 20th , 21st , 22nd positioned and safely carried. In this way, further means for arranging an assembly can be saved and the assembly can also be placed on the device base simply and securely 1 to be placed. Due to the integral design of this at least one assembly retaining wall 20th , 21st , 22nd Furthermore, work steps and other components that ensure that the assembly is carried and positioned are saved, since this can also be formed in the one punching and forming process.

Furthermore, the side wall 3 preferably at least one positioning element 40 , 41 on. These positioning elements 40 , 41 are also preferably integral with the appliance base 1 educated. In a particularly preferred exemplary embodiment, at least the assembly retaining wall also has 20th preferably integrally formed positioning elements 42 , 43 on. 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 bottom, in such a way that the positioning elements 40 to 43 one on the bottom of the device 1 Contact arranged assembly from above in such a way that a constant clamping pressure is exerted on the assembly. In this way, the assembly can be placed between the assembly retaining walls 20th , 21st , 22nd or the level 4th as well as the positioning elements 40 to 43 clamped and thus position safely, while due to the integral design of the positioning elements 40 to 43 further additional components can be saved.

How in particular 1 and 3 can be seen, the bottom part 2 preferably at least one fastening device 23 , 24 with which the control gear can be fastened. The fastening device 23 , 24 is also preferably integral with the bottom part 2 educated. In addition, the at least one fastening device is 23 , 24 preferably spaced from the assembly such that when the latter is on the bottom part 2 of the device base 1 is arranged, the operating device simply via the fastening device 23 , 24 can be attached without damaging the assembly.

Like the bottom part 2 so does the side wall 3 in a preferred embodiment, at least one fastening device 30th , 31 with which the control gear can be attached to the side. The fastening device 30th , 31 the side wall 3 is, as well as the fastening device 23 , 24 of the bottom part 2 , preferably integral with the device base 1 educated.

Through the integral design of at least one fastening device 23 , 24 , 30th , 31 on the bottom part 2 and / or on the side wall 3 these can also be formed in the one punching 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 built-in version, as will be explained in more detail below.

In a particularly preferred embodiment, the bottom part 2 also a grounding pin 6th on, which is also preferably integral with the device base 1 is trained. The ground pin 6th is preferably from the bottom of the device 1 punched out and bent accordingly so that it is off the device base 1 protrudes in such a way that the assembly is particularly easy on the ground pin 6th can be arranged and brought into contact with this. To the ground pin when arranging an assembly on the device base 1 To bring in connection with the assembly, the ground pin extends 6th preferably in the same direction from the bottom part 2 away, as does the side wall 3 from the bottom part 2 extends away. Also the ground pin 6th can consequently be formed integrally with the device base in the one punching and forming process. The ground pin 6th does not have to be riveted or pressed or otherwise attached to the device base.

The inventive design of the grounding pin 6th it is also possible to simply plug the assembly with this grounding pin 6th to bring in contact. The ground pin 6th is preferably designed as an insulation displacement contact, so that a ground contact with the module is easy and safe by simply plugging the module onto the ground pin 6th of the device base 1 can be produced. The assembly is also located when it is on the ground pin 6th is arranged, spanned in an imaginary space by floor part 2 and side wall 3 of the device base 1 and is thus very advantageously protected in the best possible way from direct mechanical influences during further handling and also offers good accessibility to the assembly.

Thus, all of the aforementioned elements are preferably formed integrally with the device base, so that work steps, components, materials and costs in the manufacture and assembly of the operating device can be saved. The use of aluminum also combines the properties of the device base 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.

4th shows, for example, an aluminum sheet BE after the punching process for the production of a device base according to the invention according to the above-mentioned embodiment. After the punching process, the entire device base can be formed in a further forming process 1 straight from this aluminum sheet BE can be produced without using additional components.

How in particular 1 can be seen, has the side wall 3 furthermore holding elements 32 , 33 on, which is preferably also integral with the device base 1 are trained. By means of these holding elements 32 , 33 is it possible to use a housing top 100 (see. 5 ) to be fixed on the device base.

The holding elements 32 , 33 are preferably on a partial area 3a the side wall 3 arranged substantially parallel to the side wall 3 is offset towards the inside of the device base. The sub-area is advantageously 3a from the side wall 3 formed in a forming or stamping-bending process, and its upper edge preferably extends up to a height of the upper edge of the side wall 3 . The sub-area is also advantageous 3a at least at its upper edge of the partial area 3a opposite side with the side wall 3 integrally connected. The connection of the side wall 3 with their sub-area 3a is preferably designed such that the sub-area 3a relative to the side wall 3 Is designed to be resilient, 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 simply place it on the device base, whereby it is securely fixed, and it can also be easily removed again.

In a particularly preferred embodiment, in addition to the side wall 3 also at least one of the assembly retaining walls 20th , 21st , 22nd also at least one holding element 34 , 35 on. These holding elements 32 to 35 are preferably all integral with the device base 1 educated. A secure fixing of the upper part of the housing 100 can thus due to the distributed holding elements 32 to 35 can be guaranteed, wherein the holding elements can be easily produced in the one punching and forming process.

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

5 shows a housing upper part 100 . The upper part of the housing 100 preferably has a cover part 101 and also preferably one or more of the cover part 101 side panels extending away in one direction 102 , 103 , 104 , 105 on. The lid part 101 as well as 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 part of the housing 100 is constructed in such a way that it is assembled with the device base 1 forms a substantially closed space in which the assembly is arranged. In this way it encloses the upper part of the housing 100 together with the device base 1 the assembly completely. The assembly is thus reliably protected from the environment and cannot be damaged by external (mechanical) influences, such as impacts or contact.

The upper part of the housing 100 can on at least one side wall 102 at least one, preferably two or more holding elements 110 , 111 have that in the assembled state of the upper housing part 100 with the ones in the device base 1 trained holding elements 32 , 33 correspond. The holding elements 110 , 111 are also preferably integral with the upper housing part 100 formed and also preferably shaped as hooking or snap-in elements. In this way, locking of the operating device can be guaranteed, while no additional locking parts are required. In addition, when hooking or latching elements are used, quick and safe locking and easy opening of the operating device is also possible.

The side wall 102 is also preferably designed such that it is with the sub-area 3a the side wall 3 corresponds in such a way that a substantially planar surface between the side walls 3 , 102 is formed, the side wall 102 so from the outside flat behind the sub-area 3a engages so that the retaining elements 32 , 33 , 110 , 111 correspond with each other. This prevents accidental opening of the upper part of the housing 100 from the bottom of the device 1 prevented. Due to the preferably resilient design of the sub-area 3a this can easily be bent towards the inside of the device base, for example by means of a tool, so that the latched holding elements are locked 32 , 33 , 110 , 111 loosen from each other and the upper part of the housing 100 can easily be removed from the device base.

In addition, the upper part of the housing 100 also preferably on one of the further side walls 103-105 at least one holding element 112 , 113 on, which in the assembled state with the corresponding holding element 34 , 35 of the device base 1 corresponds. These holding elements too 112 , 113 are preferably integral with the upper housing part 100 and can also be formed as hooking or locking elements. The locking of the operating device is thereby ensured even better.

The overlap between the upper part of the housing 100 and device base 1 in the assembled state is preferably very small in order to create a closed space on the one hand and thus accommodate the assembly in a protected manner, but this with the least possible material expenditure. In a particularly preferred embodiment there is an overlap of the device base 1 with the upper part of the housing 100 in the assembled state only in the area of the holding elements 32-35 and 110-113 in order to ensure the minimum possible use of materials. The sides of the device base close where there is no overlap 1 and the upper part of the housing 100 preferably flush with each other.

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

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

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

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

Like the one in particular 9 and 10 can be seen, there is a major difference in the device base 1' to the device base 1 that instead of the assembly retaining wall 20th a second side wall 20 ' on the, with reference to the bottom part 2 ' opposite side of the first side wall 3 ' , so also opposite the level 4 ' , extends so that the device base 1' is essentially U-shaped. That way there is one on the bottom of the device 1' arranged assembly B ' (see. 13 ) is even better protected from damage and handling is further improved, with the advantages of the device base mentioned above 1 , 1' be preserved in full.

The second side wall 20 ' is preferably essentially a mirror image of the first side wall 3 ' educated. The second side wall advantageously has 20 ' therefore also holding elements 34 ' , 35 ' (like the retaining elements 32 ' , 33 ' ), a sub-area 20a ' the side wall 20 ' (like the sub-area 3a ' ) as well as positioning elements 42 ' , 43 ' on. It is also conceivable that the second side wall 20 ' corresponding fastening devices, such as the fastening devices 30 ' , 31 ' has in order to be fastened on both sides and to increase the application possibilities of the operating device.

On the level 4 ' opposite side, i.e. on the second side wall 20 ' facing side of the bottom part 2 ' is preferably at least one assembly holding element 50 ' , 51 ' arranged. The top of the assembly retainer 50 ' , 51 ' has the same distance from the bottom part 2 ' on how the top of the paragraph 5 ' the stage 4 ' . In this way an assembly B ' on the stage 4 ' , the assembly retaining walls 21 ' , 22 ' as well as the assembly holding elements 50 ' , 51 ' positioned and securely carried and also by means of the positioning elements 40 ' to 43 ' also sure to be jammed.

The assembly holding elements 50 ' , 51 ' are preferably integral with the device base 1' formed, particularly preferably from the bottom part 2 ' punched out and bent upwards, as well as the earthing pin 6 ' . The assembly holding elements are particularly preferred 50 ' , 51 ' such to and in front of the side wall 20 ' in the bottom part 2 ' arranged that after bending down the positioning elements 42 ' , 43 ' on the bottom of the device 1' arranged assembly B ' , the positioning elements 42 ' , 43 ' with the upper edge of the assembly holding elements 50 ' , 51 ' a clamping point for clamping the assembly B ' form.

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 shoulder of this second step being essentially parallel to the bottom part 2 ' is aligned. Preferably this stage is like the stage 4 ' educated. In this case, full-surface contact is one on the first stage 4 ' and the assembly arranged in the second stage B ' enlarged and thus improved heat dissipation in several areas of the assembly B ' possible. The second stage also serves as a support for positioning the assembly B ' so that the assembly retaining elements 50 ' , 51 ' in this case are no longer required and can be omitted.

Corresponding to the U-shaped design of the device base 1' is also the upper part of the housing 100 ' compared to the upper part of the housing 100 adapted, in particular from the 11 and 12 evident. Essentially the only difference is that the side wall 103 ' now analogous to the side wall 102 ' , and thus also the retaining elements 112 ' , 113 ' analogous to the retaining elements 110 ' , 111 ' , are designed so that the holding elements 110 ' to 113 ' safe with the holding elements 32 ' to 35 ' of the device base correspond, the connection thus on both side walls 102 ' , 103 ' is formed essentially identically. At this point we refer to the corresponding descriptions of the upper part of the housing 100 referenced.

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

Particularly preferred is how 17th shows the strain relief 201 , 1201 of the upper part of the housing 200 , 1200 in the bottom part 220 , 1220 arranged, particularly preferably formed integrally with this.

18th shows a section of the in 17th shown bottom part 1220 in which the strain relief 201 , 1201 , three strain reliefs in the example shown 201 , 1201 , is or are arranged. The strain relief 201 , 1201 preferably has two opposite and, viewed in the insertion direction, left and right of a strain relief channel Z of the upper part of the housing 200 , 1200 lying tongues 1250 on. The tongue 1250 is preferably designed in the manner of a ratchet, particularly preferably having a plurality of teeth arranged one above the other 1251 having. These teeth 1251 are preferably related to the strain relief channel Z facing away from this. Furthermore, the strain relief 201 , 1201 preferably one up between the tongues 1250 preferably in a lower area of the strain relief channel Z extending retaining edge 1252 which prevents it from slipping out or being pulled out when the cable is inserted, i.e. blocks it.

In order to achieve a jamming or blocking of an inserted cable, the strain relief 201 , 1201 also preferably a strain relief lever 1260 on, which advantageously as a separate part or also integral with the upper housing part 200 , 1200 is trained. 19th shows a view like that in 18th , but with inserted strain relief 1260 . The strain relief handle 1260 preferably has guide rails on two opposite sides 1261 on into which the tongues 1250 are insertable. The strain relief handle 1260 can therefore be applied to the left and right of the strain relief channel Z arranged tongues 1250 be plugged in that it relates to the strain relief channel Z on one of the retaining edge 1252 opposite side is arranged. That of the retaining edge 1252 facing side of the strain relief handle 1260 can also be designed in such a way that it has at least one holding element for blocking a cable K having.

So that there is sufficient clamping force for the strain relief 1201 can be guaranteed, shows the strain relief 1260 within the guide rails 1261 , or on the teeth 1251 facing side of the guide rails 1261 , a clamping element 1262 on, which is preferably integral with the strain relief handle 1260 is formed and with the teeth 1251 corresponds (cf. also 22nd ). The clamping element 1262 is preferably resiliently mounted or designed so that it has a sufficient clamping force with the teeth 1251 hooked. Since preferably numerous teeth 1251 in the tongues 1250 are formed, also has the strain relief lever 1260 correspondingly many locking positions so that a secure jamming or blocking of the cable is guaranteed.

It should be noted that the strain relief 201 , 1201 are aligned parallel to each other in the examples shown. In a particularly preferred embodiment, the strain relief 201 , 1201 also at an acute angle to the face 202 , 1202 of the upper part of the housing 200 , 1200 be arranged, with at least two strain reliefs being present 201 , 1201 these can also be arranged in a fan shape to one another. In this way the accessibility of the strain relief can be reduced 201 , 1201 and the connectivity of these are facilitated. However, it is also possible to use the strain relief 201 , 1201 , as shown in the figures, to be arranged parallel to one another or in a different orientation.

With HID EVGs (electronic ballast for high-pressure gas discharge lamps) in particular, three strain reliefs are particularly preferred due to their high ignition voltage 201 , 1201 used. In the case of simpler variants, e.g. FL EVGs (electronic ballast for fluorescent lamps), fewer strain reliefs can be used, and more than three strain reliefs in the case of more complex ones 201 , 1201 be provided.

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