Abstract
The present application relates to a mount and a housing. The fastening bracket serves to fasten the first housing part of the housing explosion-proof to the second housing part of the housing. The fastening frame is embodied as a metal strip, wherein fastening regions are arranged on opposite ends of the metal strip for connecting the fastening frame to the second housing part, and at least one fastening structure is arranged between the fastening regions for firmly connecting the fastening frame to the first housing part. The fastening frame is designed with respect to material and cross-sectional dimensions such that a predetermined contact pressure is provided for the sealing element arranged between the second housing part and the first housing part, and the fastening frame is plastically deformed when a predetermined maximum explosion pressure occurs in the interior of the housing, such that an outlet gap is formed between the housing parts without the fastening frame being released from the connection with the first housing part or the second housing part. In the housing, the first housing part and the second housing part are fastened to one another explosion-proof by means of a fastening frame.
Description
Technical Field
The invention relates to a fastening bracket (Fixierb ügel) for explosion-proof fastening of a first housing part of a housing to a second housing part of the housing, and to a housing in which the two housing parts are connected to one another via such a fastening bracket.
Background
In power electronic devices (for example inverters for converting input power supplied as direct current into output power supplied as alternating current), a possible explosion of components (for example capacitors or switching modules) may occur inside the housing of these devices, the possible explosion pressure of these components increasing with the ever increasing power density due to further development. Since the current safety regulations for the design of housings for such devices are still insufficient, accidents have been reported in which persons in the vicinity of the device are injured by the housing parts released by the explosion.
It is therefore desirable to design the housing in such a way that the housing parts do not come loose even in the event of an explosion. In order not to have to produce unnecessarily stable and therefore material-intensive housing shapes, it seems advantageous to design the housing in such a way that, in the event of an explosion, the cover as the first housing part can be detached in a controlled manner from the groove (Wanne) as the second housing part, forming an outlet gap, whereby the explosion pressure can be discharged through the outlet gap.
For this purpose, document DE 202014100486 a1 proposes connecting the cover and the groove by means of a deformable fastening element having a closed ring, wherein the fastening element is screwed (versebauben) on opposite sections to the cover and the housing, respectively.
Alternatively, document DE 202015106657U 1 proposes that the housing body or the housing cover is enclosed at its fastening point with a depression such that a gap is formed between the housing body and the housing cover if the internal pressure in the housing exceeds a predetermined limit value.
SUMMERY OF THE UTILITY MODEL
The object of the invention is therefore to provide an alternative configuration of the fastening element between the housing and the housing parts of the housing, so that, in the event of an explosion, on the one hand a gap is formed between the housing parts and, on the other hand, a detachment of the housing parts is avoided.
This object is achieved by a holder and a housing having the features described below. Advantageous embodiments of the invention are given below.
A first aspect of the invention relates to a fastening bracket for explosion-proof fastening of a first housing part of a housing to a second housing part of the housing, wherein the fastening bracket is embodied as a metal strip. The first housing component may be a housing cover and the second housing component may be a housing slot. Fixing regions are arranged at opposite ends of the metal strip for connecting the fastening frame with the second housing part, and at least one fastening structure is arranged between the fixing regions for firmly connecting the fastening frame with the first housing part. The fastening bracket is dimensioned with respect to material and cross-sectional dimensions in such a way that, on the one hand, a predetermined contact pressure is provided for a seal arranged between the second housing part connected to the fastening region and the first housing part firmly connected to the at least one fastening structure. On the other hand, when a predetermined maximum explosion pressure occurs in the interior of the housing, the plastic deformation of the fastening frame should be carried out in such a way that an outlet gap for the explosion pressure is formed between the housing parts without the fastening frame being released from the connection to the first or second housing part. In this case, part of the explosion energy is already absorbed by the plastic deformation of the fastening bracket between the fastening region and the fastening element. Since the explosion pressure is discharged via the outlet gap, the pressure in the interior of the housing then drops rapidly, so that the mechanical loading of the holding structure of the housing parts occurs only briefly and the peak value of this loading is reduced in comparison with conventional, direct fastening variants of the housing parts to one another. The housing can thereby be made lighter and the fastening elements can be provided more cost-effectively, in particular in a smaller number. Preferably, the outlet gap is designed in such a way that it does not allow manual intervention inside the housing, so that the housing still provides sufficient contact protection even after an explosion.
The fastening region can be embodied as a bore, so that the fastening bracket can be screwed to the second housing part. In an advantageous embodiment, the hole can be designed as a long hole. This allows the fixing area to be laterally offset relative to the threaded connection point in the event of an explosion, which in effect increases the area of the fixing frame that can be plastically deformed to absorb the energy of the explosion.
However, it is not excluded that the fastening region has no holes and that the fastening frame is held in a correspondingly designed clamping structure (Klemmstruktur) of the second housing part only in a clamping manner. In this case, a stop, for example in the form of a nose widening of the fastening frame, is preferably provided in the fastening region, so that in the event of an explosion the fastening frame cannot be completely pulled out of the clamping structure as a result of the lateral offset.
In a preferred variant, at least one fastening structure is embodied as a threaded hole. In this way, the first housing part can be connected to the fastening frame by means of a screw element which is screwed into the threaded hole, so that an easy release of the first housing part is achieved. In this case, the fastening arrangement is usually selected in such a way that, on the one hand, a desired (usually uniform) distribution of the pressing force over the sealing element arranged between the housing parts is achieved. On the other hand, via the distance between the fastening structure and the adjacent fixing region or regions, a region of plastic deformability can be defined which absorbs a portion of the explosion energy or forms an outlet gap.
In the case of a single fastening structure, this may preferably be arranged centrally between the fixing regions, but non-central arrangements are not excluded. The centered arrangement facilitates a substantially symmetrical deformability of the fastening frame, which may be advantageous if the housing parts are largely of symmetrical construction. For example, if an asymmetric exit gap is desired, a non-centered arrangement may be advantageously used. In this case, the number and positioning of the fastening structures can also take into account the expected explosion locations and the resulting explosion pressure development in order to simulate the formation of the outlet gap in a desired manner.
Especially in the case of long fastening frames, it is advantageous to arrange a plurality of fastening structures between the fastening areas. This allows an improved distribution of the pressing force over the sealing element arranged between the housing parts. The pressing force that can be achieved in this way can be increased by arranging a further fastening region between adjacent fastening structures, in which the fastening frame can be additionally connected (for example by means of a further screw) to the second housing part. Preferably, the further fastening region or the further fastening regions can be designed in such a way that the connection of the fastening regions to the second housing part is released in the event of an explosion, so that a larger outlet gap can be produced than in the case of a non-released connection.
Preferably, the fixing frame according to the present invention may be implemented as a steel band. In one embodiment, the fastening frame has steps (Stufe) respectively arranged at the ends of the fastening area. The step may simply be formed by form pressing and results in a first plane in which the fixing region is arranged and a second plane parallel to the first plane in which the fastening structure is arranged. Such an embodiment can be fitted particularly easily in the housing.
According to a further aspect of the invention, in a housing having a first housing part and a second housing part, the first housing part is releasably connected to at least one fastening structure of a fastening frame of the housing according to the invention, and the second housing part is connected to a fastening region of the fastening frame, so that the first housing part in the assembled state is pressed against the second housing part via a seal arranged between the first housing part and the second housing part. Preferably, the connection between the first housing part and the fastening structure is provided by a threaded connection. Depending on the housing size, each sidewall may use one or more screws for the releasable connection. In this case, the side walls in a square housing mean four side regions (Seitenbereich) which are not the front side of the housing formed by the first housing part or the rear side of the housing opposite this front side formed by the second housing part.
Instead of a threaded connection, the connection between the second housing part and the fastening region can also be provided by clamping. In this case, clamping structures are provided in the second housing part, into which the fastening frame is inserted via its fastening region and is clamped there.
In one embodiment of the housing, the housing parts have circumferential sealing surfaces facing each other along the side walls of the housing, so that a seal arranged between the sealing surfaces seals the housing. The fastening frame is arranged on a side wall of the housing and in particular extends substantially along the entire length of the side wall.
The housing has at least one holder arranged on a side wall of the housing. Preferably, the housing has at least two holders, which are arranged on opposite side walls of the housing. Particularly preferably, the housing has at least four fastening brackets, which are each arranged on a different side wall of the housing. On the side wall where the fastening frame is not provided, the first housing part can be screwed directly to the second housing part or can be connected in some other way, for example via a hinge. Locking structures (arrestierungsstruktur) with which one housing part engages the other housing part at the rear can also be envisaged on the side walls which are not provided with a fastening frame.
Furthermore, it is also conceivable for the first housing part to be designed as a two-part partial cover, wherein each partial cover is connected to the second housing part via at least one fastening bracket according to the invention.
In a preferred embodiment, the housing is embodied as a housing of an inverter, in particular a solar inverter.
In a further advantageous embodiment, the housing is embodied as a housing with IP65 protection class.

Fig. 4 shows the holder according to the invention in a state of deformation due to an explosion.
Detailed Description
Fig. 1 shows an embodiment of a fastening frame 1 according to the invention. The fastening frame 1 is formed from a steel strip which is brought into the desired shape by means of customary shaping processes, such as stamping, pressing or embossing. The fastening bracket has fastening regions 2 at its two ends, in which elongated holes are respectively introduced. For example, via each slot, the fastening frame 1 can be screwed to a housing part, so that the fastening frame 1 is pressed against the housing part in the fastening region 2.
The holder 1 furthermore has two fastening structures 3, here two threaded holes. The fastening structures 3 are arranged in the regions between the fixing regions 2 and at a distance from these fixing regions, which distance defines the deformation region of the fastening frame 1. In each deformation zone, the offset of the fixing frame 1 is arranged by introducing two curved edges so that the fastening structure 3 lies in a plane parallel to the plane in which the fixing zone 2 lies. Hereby it is achieved that the screw (via which the other housing part is screwed to the holder) may protrude slightly from the rear of the fastening arrangement 3, which improves the strength of the connection.
In the embodiment shown in fig. 1, the further fixing regions 4 between the fastening structures 3 are embodied as holes. This further fixing area 4 allows the fastening frame 1 to be connected via a further fixing point to the housing part already connected to the fixing area 2. In this way, a pressing force with an improved pressure distribution, in particular a high and uniform pressure distribution, can be generated between the housing parts. For example, the fastening frame 1 can be screwed to the respective housing part by means of screws which protrude through the further fastening region 4. In this case, such a threaded connection can preferably be designed in such a way that it can be released in the event of an explosion in order to facilitate the formation of the outlet gap, in particular in the region of the further fastening region 4.
Fig. 2 shows a housing 10, in which a cover as a first housing part 11 is fitted via the fastening frame 1 according to fig. 1 with a groove as a second housing part 12. The housing 10 may, for example, house components of a solar inverter and is specifically designed to provide the solar inverter with a level of protection that is in compliance with IP65 requirements. For this purpose, the housing parts 11, 12 are sealed by a sealing element (not shown) inserted between the sealing surfaces 17.
The cover is connected with the holder 1 via screws 13 engaging into the fastening structure 3. At the same time, the fastening frame 1 is screwed to the groove in the fastening region 2 by means of screws 14. In this embodiment, the same type of fixing frame 1 is arranged on the opposite side of the housing 10. In this case, a fastening frame 15 according to the invention in simplified form is arranged on the other sides of the housing 10. The simplified fastening frame 15 here has only one fastening structure 3 between the fastening regions. The same type of mount can also be used on all four sides of the housing.
In the embodiment of the housing shown in fig. 2, the first housing part 11 has a first sub-cover 11a and a second sub-cover 11b, which each cover a sub-chamber of the housing 10 divided into two chambers. The two partial covers 11a, 11b are connected to the second housing part 12 via fastening brackets 1, 15, 16, respectively, which are shaped to match the respective lateral length of the partial covers 11a, 11 b. Both sub covers 11a, 11b are securely fastened to the second housing part 12, irrespective of the chamber in which the explosion occurs.
Fig. 3 shows the connection region between the first housing part 11 and the second housing part 12 in cross section. The fastening frame 1 is screwed in its fastening region 2 to the second housing part 12 by means of screws 14. In the middle between the fixing areas 2, the first housing part 11 is fastened to the fastening arrangement 3 with further screws 13. The housing parts 11, 12 are shown spaced apart in the cross-sectional illustration, but are pressed against one another in a sealing manner by the fastening frame 1 in a plane not visible by means of an interposed sealing element.
The pressing force on the sealing element, which is generated by the connection of the housing parts 11, 12 to the fastening frame 1, causes an elastic deformation of the fastening frame 1. In the event of an explosion at a predetermined maximum explosion pressure, the force on the fastening frame 1 exceeds the maximum value of the elastic deformation and deforms the fastening frame 1, in particular in the region between the fastening region 2 and the adjacent fastening arrangement 3, so that the distance between the housing parts 11, 12 increases, so that an outlet gap is formed. The screws 13, 14 are connected to the fastening frame 1.
The holder 1 shown in fig. 4 has plastic deformation due to an explosion. Due to the deformation, a part of the explosion energy is absorbed by the holder 1. In this case, plastic deformation occurs mainly in the section of the fastening frame 1 extending between the fastening region 2 and the respectively closest fastening structure 3.
