    MODULAR EQUIPMENT HOUSING FOR DIFFERENT TYPES OF PROTECTION
    The invention relates to housings for electronic control gear, in particular with electronic control gear housings for different types of protection.
    The term protection class is the suitability of electrical equipment, such as electrical equipment, lights or installation material, so that understand electronic components for different environmental conditions. In addition, the protection of people against possible hazards when using the electrical equipment is included.
    The term protection class describes the protection against contact voltages and includes the protection against dangerous for a person electrical voltages to operationally not live equipment. The protection classes are designated, for example, in international standards as protection class I to protection class III.
    The term protection class describes the protection against direct contact, against ingress of solids, such as dust and liquids. In the attached Fig. 2 shows a list of different types of protection and their classification is represented by means of IP codes.
    A variety of national and international standards defines the degree of protection and protection classes. For example, DIN EN 60529 (VDE 070-1: 204-09) defines the degree of protection provided by enclosures.
    For a manufacturer of electrical equipment, the task is to offer for the particular application specifically suitable and at the same time competitive in the market solutions. Thus, a manufacturer of lighting technology can interpret an LED driver for driving LEDs in lights by means of a single electronic circuit using different housing for different types of protection. Thus, while synergies in the field of electrical circuit are realized, so that the number of electronic circuits for the uniform operation of applications of different types of protection correspondingly higher fails, but are still different modules for the different types of protection that differ in terms of their housing to manufacture and logistically. This is particularly important for manufactured in large quantities resources, just as for control gear for lamps of importance.
    It is therefore the task of finding housing for housing in the field of electrical equipment cost-efficient solutions across the range of several types of protection.
    The arrangement according to claim 1 solves the problem. Advantageous developments of the arrangement according to the invention are defined in the subclaims.
    The invention includes an arrangement with a control gear for lights and designed with a housing for receiving an electronic module with first electrical connection means, wherein the housing is designed for a first degree of protection and the first connection means are accessible from outside the housing 2 , Furthermore, the arrangement comprises a cover device with second electrical connection means and third electrical connection means, the second electrical connection means being electrically conductively connected to the third electrical connection means, and the second electrical connection means of the cover device being electrically conductively connectable to the first electrical connection means of the housing. The third electrical connection means are designed to allow an electrical contact with a second degree of protection higher than the first degree of protection when the cover device is connected to the housing.
    The operating device may in particular include a converter circuit, for example as a driver (ballast) for lighting. The lighting means may be, for example, gas discharge lamps or light emitting diodes (LED). Just such converter circuits are in large
    Quantities for different types of protection, for example, for applications in homes, but also for different locations in wet rooms, used outside in buildings, in industrial applications as well as in the field of automotive technology. Each of these applications is subject to their own protection requirements, possibly also regionally different standards and legal requirements. At the same time, high quantities are produced, so that in the field of lighting technology the economies of scale of production will have a particularly advantageous effect.
    Thus, according to the invention, a single housing can meet the requirements for different degrees of protection. If the housing is used without covering device (cover), all prerequisites with respect to the first, lower degree of protection are fulfilled and the module can be electrically contacted via the first electrical connection means of the housing. If the cover device is additionally attached, the higher requirements of the second degree of protection are fully met without having to develop, manufacture and logistically support a completely separate housing with connection means selected according to the degree of protection. At the same time, the basic version of the electronic control gear only includes the cheaper because of their lower requirements electrical first connection means, but only just ensure the fulfillment of the first degree of protection. If the basic version of the electronic control gear is supplemented with the cover device for operation with the second degree of protection, the basic version can only be supplemented with an additional module for the extended use range of the second degree of protection. This means that the costs for the manufacturer of the electronic module are lower than if the same market is covered by means of two electronic modules developed specifically for each type of protection.
    According to one embodiment of the invention, the arrangement is characterized in that the housing or the cover device comprises a receiving means and the reverse cover device or the housing has a sealing edge. In this case, the receiving means and the sealing edge are designed to cooperate such that there is a seal between the housing and cover according to the second degree of protection.
    By the receiving means and the sealing edge a seal between the housing and covering device can be achieved in a simple manner, which meets the higher requirements of the higher degrees of protection, in particular, an improved tightness against dust and water and difficult accessibility in terms of touch fulfilled.
    In addition, arrangement, in particular comprising an additional sealing means, wherein the sealing means is designed to cooperate with the receiving means and the sealing edge such that a seal between the housing and covering device according to the second degree of protection is achieved. The sealing means is preferably elastic to be deformable by the sealing edge. An example of this is a silicone cord.
    The additional sealant can allow a particularly secure seal against small particles and liquids even at high pressure and beyond the fulfillment of additional requirements for sealing against magnetic, electric fields and electromagnetic waves.
    An embodiment of the arrangement according to the invention is characterized in that the covering device comprises fixing means. The fixing means are designed so that they cooperate with further fixing means of the housing such that the covering permanently or detachably fixed to the housing is connected.
    An advantageous arrangement is characterized in that the fixing means comprises at least one locking lug and the further fixing means comprises at least one recess.
    Locking lug and recess are easy to form on the housing and the cover and allow a reliable relative fixing of the cover to the housing, without the manufacturing and assembly costs for the fixing means are significantly higher. In particular, attachment of the cover to the housing without additional tools, such as a screwdriver, possible. Further, all necessary for a detachable or permanently fixed connection between the housing and cover elements are thus fixed to the housing and cover available, additional loose elements such as screws omitted.
    In the following, embodiments of the invention will be described with reference to the accompanying figures, in which Fig. 1 shows a view of an inventive arrangement of an electronic control gear with a housing and a cover designed to increase the protection of the housing, Fig 2 shows an overview of the requirements from different degrees of protection according to a corresponding standard, [0022] FIG. 3 shows a partial view of an arrangement according to the invention with a housing and a cover, [0023] FIG. 4 shows a further partial view of an arrangement according to the invention with a housing and a housing Cover, and [0024] FIG. 5 is another partial view of an assembly according to the invention with a housing and a cover.
    In the figures, like reference numerals refer to the same or corresponding elements. On a description with like reference numerals designated elements in different figures is largely dispensed, as far as possible, in favor of a concise presentation.
    Fig. 1 is a view of an inventive arrangement 1 of an electronic control gear with a housing 2 and in addition a cover 5 (cover 5) to increase the degree of protection. In this case, the housing (control gear housing) 2 and the cover 5 is shown in a separated state in an oblique view. By means of arrows, the possibility of assembling the housing 2 with the cover 5 is indicated in FIG. In a separate state of the housing 2 and the cover 5, the housing 2 fulfills the requirements that result for a first degree of protection. These requirements may be, in particular, requirements regarding the protection against the ingress of foreign bodies, the protection against contact by persons or the protection against penetrating moisture, for example water, as will be explained in more detail below with reference to FIG.
    The housing 2 fulfills these requirements by enclosing an electronic assembly of the operating device located in the interior, for example with a populated electrical circuit board 8.
    The housing 2 may be made of plastic, for example. The housing 2 can be manufactured in plastic injection molding. The housing 2 can also be made of a metal or a metal alloy and thus possibly meet higher requirements with regard to electromagnetic compatibility (EMC) and shielding of electrical and magnetic fields, as well as electromagnetic waves.
    The housing 2 can be executed in one or more parts.
    Furthermore, the housing 2 comprises externally accessible first electrical connection means 3, 4. Alternatively or additionally, the housing 2 may have only one or more electrical connection means, possibly arranged on at least one further side of the housing 2.
    The first electrical connection means 3 and 4 allow the electrical contacting of the electronic assembly.
    The first electrical connection means 3 and 4 may each be, for example, as
    Terminal blocks are designed for cores of one or more electrical lines.
    The first electrical connection means 3 and 4 can serve the power supply of the electronic assembly with a conductor L1, a neutral conductor N and a protective conductor PE. The first electrical connection means 3 and 4 can enable an electrical connection of consumers to the electronic module. The first electrical connection means 3 and 4 can serve an electrical and / or optical signal transmission, for example by means of a connection to a bus.
    In the embodiment of the housing 2 shown, the first degree of protection afforded by the housing 2 is essentially determined by the arrangement and design of the first electrical connection means 3 and 4.
    Fig. 1 illustrates the cover 5 separately from the housing 2. The cover 5 is formed so as to completely cover a portion of the housing in which the first electrical connection means 3 and 4 are arranged.
    The cover 5 may preferably be made in one piece, but also in several parts.
    The cover 5 may be made of plastic and / or of a metal or a metal alloy, and thus possibly meet higher requirements with regard to electromagnetic compatibility (EMC) and shielding of electrical and magnetic fields, as well as electromagnetic waves.
    Fig. 1 further shows second electrical connection means 6, 7 of the cover 5, which are connected to third electrical connection means 6, 7, wherein the third electrical connection means 6, 7 are accessible when mounted on the housing 2 cover 5 from the outside.
    The third electrical connection means 15 of the cover 5 allow the electrical contacting of the electronic assembly, when the cover 5 is attached to the housing 2 and the second connection means 15 to the first connection means 3, 4 are conductively connected.
    The third electrical connection means 6, 7 of the cover 5 can each be designed as terminals for cores of one or more electrical lines.
    The third electrical connection means 6, 7 of the cover 5 can in particular serve the power supply of the electronic assembly with a conductor L1, a neutral conductor N and a protective conductor PE. The third electrical connection means 6, 7 of the cover 5 can enable an electrical connection of consumers to the electronic module. The third electrical connection means 6, 7 of the cover 5 can enable an electrical and / or optical signal transmission, for example the connection to a bus.
    In the embodiment of the arrangement according to the invention shown, the second degree of protection provided by the housing 2 with the cover 5 attached is essentially determined by the arrangement and design of the third electrical connection means 6, 7 of the cover 5. Accordingly, the third electrical connection means 6, 7 of the cover 5 according to the invention are designed so that they allow electrical contact with a second degree of protection higher than the first degree of protection.
    The first electrical connection means 3, 4 of the housing 2 can be selected simpler and therefore less expensive due to the lower requirements for the degree of protection to be fulfilled, as the electrical connection means 6, 7 of the cover. 5
    For the formation of the cover 5 and in particular the second electrical connection means 15 of the cover 5, reference is also made in particular to the illustration in and the discussion of FIG. 3.
    In Fig. 1, an electronic assembly in a housing 2 with arranged on one side of the housing 2 contact possibilities by means of first electrical connection means 3, 4 of the housing 2 is shown. However, the invention is not limited to this embodiment. The invention can also be applied, for example, to electrical assemblies having a plurality of electrical contact possibilities on different sides of the housing 2, in particular also on two sides of the housing 2. This is easy to effect by means of a correspondingly multi-part cover 5.
    Fig. 2 gives an overview of the requirements of different types of protection according to a standard to be applied. Fig. 2 refers in particular to IEC 60529 (Ed.2.1), Section 4.1 (clause 4.1) for the definition of protection.
    For example, two codes are added to the above letters IP of the protection class (IP code). These indices, according to the tables in Fig. 2, indicate the scope of protection afforded by a package housing and an electrical assembly in terms of safety against contact and intrusion of foreign bodies according to the first digit and protection against water according to the second code number of the protection designation.
    For the sake of clarity, the discussion of further distinctions, for example, a third digit, as for example for the classification of mechanical protection in terms of mechanical force or a third code letter for access to vulnerable active parts of the electronic module or a fourth code letter waived.
    For example, a basic version of the electronic assembly may be designed for IP 20 protection, as is typical for dry indoor applications. The basic version therefore fulfills the requirements of IEC 60529 (Ed.2.1), section 4.1, with regard to foreign bodies and contact, but there is no protection against liquids such as water.
    By supplementing the electronic module and its housing 2 with the cover 5 for the arrangement according to the invention, however, for example, the requirements of protection IP65 of IEC 60529 (Ed.2.1), Section 4.1 are met with respect to foreign bodies and touch, and protection against liquids. The supplemented arrangement according to the invention is now dust-tight, completely protected against contact and, in addition, against jet water from any angle.
    2, it is also apparent that the operation of different requirements of the respective arrangement with a common design of the electronic module, just in the area of the housing by means of application of the invention is possible. The number of different assemblies in the manufacturer's portfolio will be reduced accordingly. This reduces development costs, in particular in the area of mechanical assembly housing development, manufacturing costs, in particular because of larger batch sizes for less different parts to be manufactured and logistics costs, in particular because of the smaller number of different parts to be managed. The proposed technical solution is therefore economically advantageous.
    Fig. 3 shows a partial view of an inventive arrangement 1 with an electronic assembly with a housing 2 and a cover 5 in the assembled state. The arrangement 1 of Fig. 3 therefore meets the requirements of a second, higher degree of protection, while the assembly in the housing 2 without the mounted cover 5 only meets the requirements for the first degree of protection, which are less than that for the second degree of protection.
    Details of the cover 5 with the second electrical connection means 15 of the cover 5 and third electrical connection means 6, 7 of the cover 5 can be seen in particular from FIG.
    The second electrical connection means 15 of the cover 5 are electrically conductively connected to the second electrical connection means 6, 7 of the cover 5.
    When the cover 5 is connected to the housing 2, the first electrical connection means 3 and 4 of the housing 2 are thus connected to the third electrical connection means 6, 7 of the cover 5 via the second connection means 15. In particular, each individual electrical contact of the first electrical connection means 3 and 4 is therefore connected on the one hand to an electrical contact of the second electrical connection means 15 of the cover 5 on the other hand. Thus, the electronic assembly in the housing 2 are electrically contacted even when mounted on the housing 2 cover 5 to the same extent, as is possible without attached cover 5 for the electronic assembly via the first electrical connection means 3 and 4 of the housing 2.
    The second electrical connection means 15 of the cover 5 can be designed as short line sections, which are respectively inserted and clamped in corresponding terminal entries of the first electrical connection means 3 and 4 of the housing 2, before the cover 5 is fixed to the housing 2. In Fig. 3, only a first electrical connection means 15 is shown. Typically, several electrical connection means 15 will be present. Preferably, a second electrical connection means 15 is provided for each first electrical connection means 3 and 4 of the housing 2 in order to connect each first electrical connection means 3 and 4 of the housing 2 to the corresponding third electrical connection means 6, 7 of the cover 5.
    In Fig. 3, the second electrical connection means 15 of the cover 5 is shown with a short conductor section. Likewise, the second electrical connection means 15 of the cover may comprise a suitable connector, which cooperates with mounted on the housing 2 cover 5 with the first electrical connection means 3 and 4 of the housing 2 so that an electrically conductive connection is made.
    In Fig. 3, the arrangement of the electronic module in the housing 2 is visible in partial section. The electronic module comprises one or more printed circuit boards 8, which is equipped with electrical components 17. The electronic assembly may include, for example, one or more converter circuits of a driver for LED, as well as the circuits that may be present to operate those converter circuits, such as microcontrollers, power factor correction (PFC) circuits, rectifier circuits, communication and control circuits.
    The circuit board 8 may be further mechanically connected to the first electrical connection means 3 and 4 of the housing 2. In particular, the first electrical connection means 3 and 4 of the housing 2 can be mounted directly on the printed circuit board 8.
    It is advantageous if first the printed circuit board 8 is arranged in the interior of the housing 2 and then free areas within the housing 2 are potted with a potting compound 16.
    Further, the circuit board 8 with a web 18 in the interior of the housing 2 cooperate so that a first region in the interior of the housing 2 is separated from a second region in the interior of the housing 2. The first region of the housing 2 essentially contains functional blocks of the electronic assembly and is not accessible from outside after assembly of the electronic assembly in the housing 2. In particular, the first region of the housing 2 may be filled with the potting compound 16. The second area in the interior of the housing 2 essentially comprises the first electrical connection means 3 and 4 of the housing 2. In the case of cover 5 not attached to the housing 2, the second area of the housing 2 is accessible from the outside. This accessibility of the second area of the housing 2 is used in particular for the electrical contacting of the electronic module via the first electrical connection means 3 and 4 of the housing 2.
    The second area inside the housing 2 may be partially filled with potting compound 16.
    The second region of the housing 2 is covered by the cover 5 to the outside. If the cover 5 is attached to the housing 2, then the second area of the housing 2 with the first electrical connection means 3 and 4 of the housing 2 is closed by the housing 2 and the cover 5 with respect to external action. At the same time by the cover 5 in connection with the housing 2, the fulfillment of the requirements of the second degree of protection, for example with regard to the penetration of foreign bodies such as Dust, with regard to the contact protection of live parts and the ingress of water, ensured. For this, the corresponding design of the housing 2 and the cover 5, in particular with the function of an electrical interface accepting third electrical contact means 6, 7 provide.
    Fig. 4 shows a further partial view of an inventive arrangement of an electronic module with a housing 2 and a cover 5. In Fig. 4 by means of the sectional view, in particular a design shown in which the housing 2 is a sealing edge 13 and the cover. 5 a sealing edge 14 comprises. The receiving means 13 of the housing 2 and the sealing edge 14 of the cover 5 are designed so that they cooperate so that a seal between the housing 2 and cover 5, which meets the applicable requirements of the second degree of protection, is produced. This seal can be done directly between the housing 2 and the cover 5. Shown in Fig. 4 is the formation of the sealing edge 14 as a web with a cutting edge and the receiving means 13 as a groove in the cover 5, wherein in the groove, an additional sealing means 12 is inserted.
    The sealing means 12 may be formed as a silicone sealing cord or NBR seal.
    The sealing means 12 may alternatively be formed as or in addition with an HF strand.
    The sealing means 12 is in particular designed to cooperate with the receiving means 13 and the sealing edge 13 such that a seal between the housing 2 and cover 5 is achieved according to the second degree of protection.
    Alternatively or additionally, the sealing of the second region of the housing 2 via a corresponding positive connection of the receiving means 13 and the sealing edge 14 can be achieved.
    It should be noted that the receiving means 13, the sealing edge 14 and the sealant 12 are shown in Fig. 4 only in a partial section. It is particularly advantageous if all these elements around an opening of the second region of the housing 2 and a corresponding in an assembled state of the cover 5 region of the cover 5 are formed circumferentially.
    Fig. 5 shows a further view in partial section of an inventive arrangement 1 of an electronic module with a housing 2 and a cover 5. The cover 5 is attached to the housing 2 so that the requirements of the second degree of protection are met. In particular, details of the arrangement of an advantageous embodiment of the covering device with fixing means 5.2 are shown in FIG. The fixed-laying means 5.2 are formed as shown in FIG. 5 as latching lugs, which are arranged on an inner side of a side wall 5.1 of the cover 5. The fixing means 5.2 are shaped so that they cooperate with further fixing means 2.2 of the housing 2 such that the cover 5 is fixedly connected to the housing 2.
    The further fixing means 2.2 may be formed in FIG. 5 as a recess in an outwardly directed side surface of a side wall 2.1 of the housing 2 in the second region of the housing 2. If the cover 5 is attached to the housing 2, the locking lug of the cover 5 engages in the recess of the housing and sets the cover 5 and the housing 2 relative to each other and in particular the sealing edge 14 permanently in the elastic sealant 12th
    In Fig. 5, an embodiment of a fixing device 11 comprising a fixing means 5.2 and a further fixing means 2.2 is shown. One or more Festlegevorrich-tions 11 for a detachable or permanent connection of the cover 5 and the housing 2 can be seen before.
    It is also possible that the fixing device 11 are realized alternatively or additionally by means of one or more screws and correspondingly arranged threaded bushing.
    In one embodiment, the cover uses 5 fixing means 5.2, which cooperate with a device for strain relief of connecting cables of the housing 2, which are not used when attaching the cover 5 to the housing 2.
    The features of different embodiments can be combined with each other within the scope of the invention defined in the accompanying claims.
