Description

[0001] Device for connecting to a housing

[0002] The invention relates to a device for accommodating an electrical circuit.

[0003] The device is designed for connection to a further housing containing further electrical and / or electronic components, which may include an energy storage device. The device itself can be designed as a housing. A system comprising the device and the further housing can form a circuit system for use in electrical control systems or the like.

[0004] Devices are known that accommodate a circuit board with electrical and / or electronic components that are connected to components in the additional housing. The electrical and / or electronic components in the additional housing can be designed as an electrical energy storage device. The circuit board that can be accommodated in the device is electrically connected or connectable to the components in the additional housing. An electrical circuit formed by the circuit board and its components can control and moderate the operation of the energy storage device.

[0005] Separate mechanical fasteners of the device can be used to secure the circuit board. Various types of fasteners can be used, such as screws, rivets, clamps, or the like, which at least partially require the use of tools. The use of tools can include the use of various tools, such as various screwdrivers, wrenches, gauges, or riveting tools.

[0006] Furthermore, the electrical connection of the energy storage device to other components of a switching or control device can be established via the circuit board arranged in the device, whereby the circuit board has corresponding interface components for this purpose. The device has openings and receptacles corresponding to the interface components.

[0007] However, assembling the device requires a multitude of assembly steps to properly position and secure the device's mechanical components and the circuit board. In particular, the use of different connection techniques, possibly in conjunction with different tools, can make assembly complex.

[0008] The invention is therefore based on the object of providing a technology that simplifies the assembly of the device and the circuit board arranged therein. This object is achieved by the features of the independent claims. Expedient embodiments and advantageous further developments of the invention are specified in the dependent claims.

[0009] Embodiments of the invention, which can be optionally combined with one another, are disclosed below with partial reference to the figures.

[0010] A first aspect relates to a device for receiving a printed circuit board populated with electrical or electronic components. The device comprises a first housing part for receiving the populated printed circuit board. Guide elements are designed to receive the printed circuit board, wherein the guide elements can be designed as a slot or groove and / or as an upstanding web. The device further comprises a second housing part for covering the first housing part. The second housing part can be mounted on the first housing part without tools. The second housing part comprises a further web for stiffening the second housing part in the longitudinal direction.

[0011] The first housing part (basic housing part) can be designed as a tray suitable for accommodating the printed circuit board. The tray can include the guide elements as well as stiffening ribs and fastening elements for additional components to be accommodated for later operation as a mechanical and electrical interface for a connectable electrical energy storage device. Guide elements for one or more additional printed circuit boards can also be provided. The printed circuit boards can be held in position via guide rails on the sides and additionally or alternatively via raised webs.

[0012] The second housing part (housing cover) can comprise a flat, smooth surface on its outer side facing away from the first housing part in the assembled state, which is closed except for any existing openings. In addition to the surface, the outer side can comprise further elements that can be arranged at right angles to the surface and can comprise flat and, additionally or alternatively, curved partial elements. On its inner side, the second housing part can comprise guide elements as well as stiffening ribs and / or fastening elements for components to be mounted. The stiffening ribs can be designed as a single web or as a double web, whereby the double web can also comprise transverse ribs for connecting the two webs. The webs can have a height corresponding to the wall thickness of the housing parts. Alternatively or additionally, the webs can also have a height many times the wall thickness of the housing parts.Transverse ribs can be arranged to stiffen the webs, which taper with increasing web height. The additional web can be arranged longitudinally parallel to a pivot axis of the second housing part and can have essentially the length of the long side of the second housing part.

[0013] The first housing part and the second housing part can be made of or consist of plastic, for example, as injection-molded parts. The housing parts can have a certain degree of elasticity, so that locking hooks, locking lugs, or similar elastic elements can be implemented as elements of the injection-molded parts. Alternatively or additionally, the guide elements can be components of the injection-molded parts. Accordingly, the injection-molded parts can comprise all necessary features or components of the first housing part or the second housing part, thus eliminating the need to complete the respective injection-molded part to form the first or second housing part.

[0014] Advantageously, two torsion-resistant housing parts can be formed by the trough-shaped design of the first housing part on the one hand and the stiffening of the second housing part by the further web on the other hand, so that their reliable mechanical connection by means of molded-on connecting elements is possible.

[0015] In embodiments, the second housing part may comprise a first recess for the passage of electrical conductors.

[0016] The first recess can be arranged on the surface of the second housing part. The first recess can be surrounded on all sides by the surface of the second housing part.

[0017] Additionally or alternatively, the first recess can also be arranged on the other elements of the outer side. Further additionally or alternatively, the first recess can also comprise parts of the surface and connected parts of the other elements. The first recess can be suitable for the passage of several cables (i.e. insulated conductors) which are designed, for example (e.g. according to the nominal sizes of the batteries) for voltages of 12 V or 24 V to 48 V or between 400 V and 800 V, or charging or discharging currents of 1 A, 20 A or 100 A, or for battery charging capacities of 10 Ah to 300 Ah, or for battery energy capacities of 50 Wh to 50 kWh or more (e.g. 128 kWh).

[0018] The electrical energy storage device can also be referred to as a battery (or batteries). The electrical energy storage device can preferably be rechargeable, i.e., comprise secondary cells. Advantageously, cables running transversely (e.g., at right angles) to the surface (and optionally also at least temporarily diagonally) can be inserted through the first recess into the second housing half without being impaired by mechanical stress or kinks.

[0019] In further embodiments, the first housing part and, additionally or alternatively, the second housing part can be connected to one another or can be connected by first fastening elements. Additionally or alternatively, the first housing part and, additionally or alternatively, the second housing part can be connected to another housing or can be connected by second fastening elements.

[0020] The first and, additionally or alternatively, the second fastening elements can be designed as locking hooks and locking lugs, wherein the locking hooks are inserted into corresponding locking hook recesses when the housing parts and / or the additional housing are joined together. Locking lugs can be designed as spring elements that hook behind the housing (or housing element) to be secured (e.g., in a form-fitting manner), so that the housing to be secured is secured on one side by locking hooks and on the opposite side by locking lugs.

[0021] For example, locking lugs can be formed in the first housing part for securing the second housing part. Corresponding locking hooks can also be formed in the first housing part, which, together with the locking lugs, lock the housing parts together when the first housing part is joined to the second housing part.

[0022] Furthermore, locking hooks and, alternatively or additionally, locking lugs for securing the device to the additional housing can be arranged on the first housing part or, alternatively or additionally, on the second housing part. The additional housing can be designed as an injection-molded plastic part or as a sheet metal housing. The additional housing can include an electrical energy storage device.

[0023] The advantage of this type of locking is that it can be carried out without tools, which simplifies, speeds up and reduces the cost of assembly.

[0024] In other embodiments, the second fastening elements can comprise guide rails and, alternatively or additionally, locking hooks and, alternatively or additionally, locking lugs which are arranged on a holding plate of the device which projects from the device when the first housing part is assembled with the second housing part. The second fastening elements can be arranged on the upper side of the holding plate which faces away from the first housing part. In this case, the holding plate can be arranged below the further housing. Alternatively, the second fastening elements can be arranged on the underside of the holding plate which faces the first housing part. In this case, the holding plate can be arranged in the further housing, for example on the bottom of the further housing facing the device.

[0025] The first housing part can be assembled with the other housing first. The second housing part can then be mounted. This second part can be designed to allow a further connection to the other housing, independent of the fastening elements on the mounting plate. These can also be designed as locking hooks and corresponding locking lugs.

[0026] Advantageously, the connection of the device to the other housing can be improved and the additional connection to the other housing can additionally serve as a security feature in case locking lugs break.

[0027] In exemplary embodiments, the additional housing can be designed as a battery housing. Optionally, the first recess can be at least partially facing the additional housing when the additional housing is assembled with the second housing part.

[0028] The additional housing can have a recess corresponding to the arrangement of the first recess in the second housing part for routing the cables between the device and the additional housing. The additional housing can be made of sheet metal. When the device and the additional housing are connected, the recesses are at least partially covered, making them difficult to access from the outside.

[0029] This advantageously allows a protected routing of the cables between the device and the other housing.

[0030] In further embodiments, the contours of the first housing part and the second housing part that touch each other in the assembled state can be designed to form a closed housing.

[0031] Protection can be provided, for example, by a comprehensive and parallel contour guide of the contacting edges of the first housing part (base housing part) and the second housing part (housing cover), whereby the contacting edges can be designed to be dust- and moisture-tight. This advantageously protects the electrical circuitry of the circuit board from dust and moisture.

[0032] In other embodiments, the first housing part and / or the second housing part may comprise locking hooks for mounting the first housing part to the second housing part.

[0033] The fastening elements, designed as locking hooks, are elements of the respective injection-molded part. They are connected to the respective housing part. They are elastically spring-loaded and, when appropriate force is applied, can engage in designated locking hook recesses through deformation, which can also elastically deform the corresponding housing part. Once the force is removed, the locking hooks return to their original position and, together with other locking hooks or other stop elements, such as locking lugs, can lock the first housing part to the second housing part. The locking connection can be released by deforming the locking hooks again. The locking hooks can perform a plurality of engagement and disengagement processes without sustaining damage. Locking lugs are also designed for elastic movement.

[0034] This advantageously allows for a reliable and cost-effective locking of the housing parts.

[0035] In embodiments, the first housing part (basic housing part) may comprise a second recess for receiving (e.g. at least) one electrical fuse.

[0036] The electrical fuse can be designed as a melting fuse. This can be cylindrical or flat with blade contacts. The second recess allows access to the fuse and its replacement when the device is connected to the other housing.

[0037] Advantageously, a fuse change can be carried out without dismantling the device and other housing.

[0038] In further embodiments, the first housing part (basic housing part) can include a third recess for accommodating a backup fuse. The contour of the third recess can correspond to the contour of the additional recess.

[0039] Furthermore, a receptacle for the reserve fuse corresponding to the third recess in the dimensions of the reserve fuse can be provided in the first housing part, which is suitable for the mechanical holding of the reserve fuse.

[0040] Advantageously, such a fuse defect can be easily remedied by using the provided reserve fuse.

[0041] In other embodiments, the first housing part may comprise a fourth recess for receiving electrical contact elements, which in turn are designed for connecting external wires.

[0042] The contact elements can be screw terminals, which can be designed individually or as a block. The fourth recess can be a U-shaped recess on an outer edge of the first housing part, allowing the electrical contact elements to be inserted from above. The missing boundary of the fourth recess can be formed by the mounted second housing part (housing cover).

[0043] Furthermore, the first housing part can comprise lateral stable guide elements on the sides of the electrical contact element.

[0044] This advantageously provides a stable mounting of the electrical contact elements, which mechanically secures the contact elements.

[0045] In embodiments, the fourth recess and the first recess may be arranged in corresponding positions.

[0046] A corresponding position is understood to be an aligned position in which the outer edges of the fourth recess and the first recess coincide or correspond in the longitudinal direction of the first housing part. This correspondence can, for example, allow the insertion of an electrical contact element of constant width into both recesses if the fourth recess is arranged in the base of the first housing part and the first recess is arranged in a side wall of the first housing part. Insertion can occur from above into the first housing part.

[0047] Advantageously, safe electrical contact elements with multiple access can be used, whereby one access can allow the insertion of wires and the other access can allow the wires to be screwed in.

[0048] In further embodiments, the additional web can be used to stiffen the second housing part (housing cover) in the longitudinal direction, preventing the circuit board from falling out. Alternatively or additionally, the additional web can be designed to rest against the accommodated circuit board.

[0049] The additional web, due to its aforementioned design (single web; double web, optionally with transverse ribs) and arrangement (longitudinal direction parallel to a pivot axis of the second housing part), stiffens the second housing part. To prevent the circuit board from falling out, the additional web can be arranged above the circuit board. Alternatively, the additional web can also be arranged in a different position than above the circuit board. In this case, the stiffened housing wall of the second housing part (housing cover) prevents the circuit board from falling out. In the alternative case where the circuit board rests against the additional web, the latter is arranged above the circuit board.

[0050] When the second web prevents the circuit board from falling out when the device is assembled, the circuit board arranged in the first housing part can have clearance relative to the second web. Alternatively, the circuit board can be secured in the device when the second web is in contact.

[0051] This advantageously allows for various optimizations of the device, either by increasing the tolerances of the circuit board and housing parts or by improving the resistance to mechanical shock.

[0052] In other embodiments, the first housing part can be designed as a housing tray. Alternatively or additionally, the second housing part can be designed as a housing cover.

[0053] A housing tray, also referred to as a base housing part, is formed by a tray that is open at the top and comprises a housing base and adjoining housing side parts that extend from the housing base in the same direction and are connected at their corresponding edges to the housing base and the adjacent housing side parts. The housing tray can be designed to accommodate components, for example, it can provide corresponding fastening elements, guide rails and / or recesses and the like. Furthermore, it can also comprise fastening elements for the housing cover and, additionally or alternatively, for other housings, for guide rails, wall mountings, or the like.

[0054] A housing cover closes the housing tray, similar to how a lid closes a pot. The housing cover and the housing tray can have comprehensive and parallel contours along the contacting edges of the housing cover and the housing tray. Optionally, contacting edges can be designed to be dust- and moisture-tight. The housing cover can include fastening elements for the housing tray and, in addition or as an alternative, for other housings, for guide rails, wall mountings, or the like.

[0055] When assembled, the housing cover and housing tray can form the device.

[0056] This advantageously allows the arrangement of components to be limited to the housing tray, which simplifies the assembly process.

[0057] In embodiments, the first housing part and alternatively or additionally the second housing part can be made of plastic.

[0058] The plastic can be suitable for processing in injection molds. In its typical processed form, for example as a housing cover or housing tray, it demonstrates a certain elasticity, so that the use of molded-on fastening elements in the form of locking hooks and corresponding locking openings, locking lugs or the like is possible during assembly. The application of force causes a temporary elastic deformation of the components. This allows the locking hooks and the corresponding locking openings, which can also be referred to as locking hook recesses, locking lugs or the like, to be brought together or inserted. Once the force is removed, the components return to their original shape, so that the housing parts lock together. Locking takes place without the need for tools.

[0059] In general, a wide variety of thermoplastics, thermosets, and elastomers are suitable for injection molding. Engineering plastics such as PA6, PA66, PBT, PES, POM, and PSU are available for injection molding technical plastic parts.

[0060] This advantageously eliminates the need for additional fastening elements, making installation easier and cheaper.

[0061] A second aspect relates to a system for providing electrical energy, for example an uninterruptible power supply. The system comprises a device according to the first aspect or one of the associated exemplary embodiments. The system further comprises a printed circuit board with electrical and / or electronic components, which is arranged or can be arranged in the device, in particular in the housing tray. The printed circuit board can be arranged without tools. The system further comprises a further housing. The further housing in turn comprises an electrical energy store (i.e. a power store), for example in the form of an electric battery. The device and the further housing are mechanically connected to one another (for example in a form-fitting and / or reversible manner). The printed circuit board and the power store are electrically connected to one another.

[0062] The additional housing can be made of or consist of sheet metal. The additional housing can have fastening elements corresponding to the fastening elements of the retaining plate of the first or second housing part for locking the device and the additional housing together. Alternatively or additionally, the additional housing can be made of or consist of plastic, at least in part.

[0063] The electrical connection between the circuit board and the power storage device can comprise wires, cables, and alternatively or additionally, lines for transmitting electrical energy and / or signals (e.g., for voltage or temperature measurement in the power storage device). One or more batteries can be arranged in the further housing, the electrical connections (battery terminals) of which, in the case of a plurality of batteries, are individually connected to the circuit board in the device. Furthermore, electrical connections for monitoring the batteries can be part of the electrical connection, for example, for temperature monitoring of the batteries, for voltage monitoring of individual battery cells, or the like.

[0064] Further preferably, the energy storage device (i.e. the power storage device, e.g. the battery) can have electrochemical cells with lithium iron phosphate or be designed as a pure lead AGM (technical term: Absorbent Glass Mat) or as a lead AGM.

[0065] The additional housing may comprise additional fastening means, for example, for fastening to a guide rail (e.g., to a support rail, in particular a top-hat rail), which in turn may be arranged in a control cabinet. Alternatively or additionally, the fastening means may also comprise components for wall mounting.

[0066] At least one recess in the first housing part, and alternatively or additionally in the second housing part of the device, can spatially correspond with a corresponding recess in the further housing, so that the wires, cables, or lines between the device and the further housing are conveniently arranged. This advantageously provides a compact component that is resistant to voltage fluctuations or power outages.

The device 100 is suitable for receiving a printed circuit board populated with electrical or electronic components. The device comprises a first housing part (basic housing part) 110 for receiving the populated printed circuit board. The guide elements 120 are designed to receive the printed circuit board. The guide elements 120 are designed as a slot and additionally or alternatively as a groove and additionally or alternatively as a raised web (not shown). The device 100 further comprises a second housing part (housing cover) 130 for covering the first housing part 110. The second housing part 130 can be mounted on the first housing part 110 without tools.Furthermore, the second housing part 130 comprises a further web 140 for stiffening the second housing part 130 in the longitudinal direction, parallel to a pivot axis of the second housing part 110. The further web 140 is arranged correspondingly to the guide elements 120 of the first housing part, so that the circuit board is surrounded on all sides when the housing parts are assembled. Alternatively, the further web 140 can also be arranged differently from the guide elements 120 of the first housing part 110, so that the circuit board does not face the further web 140 when the housing parts are assembled.

[0081] Fig. 2 shows a schematic diagram of a second housing part 130 of a device 100 according to the first aspect in one exemplary embodiment. The second housing part 130 of the device 100 comprises a first recess 150 for the passage of electrical conductors. The first recess is arranged centrally in the longitudinal direction of the second housing part. Alternatively, the first recess can also be positioned deviating from the central arrangement.

The first housing part 110 and the second housing part 130 can be connected or are connected to one another by first fastening elements 160. Additionally or alternatively, the first housing part 110 of the device 100 and additionally or alternatively the second housing part 130 of the device 100 can be connected or are connected to a further housing 180 by second fastening elements 170 (not shown for the first housing part 110). The first fastening elements 160 are shown as rectangles and can be designed, for example, as latching hooks 210 and latching lugs 220, wherein the latching hooks engage in corresponding latching hook recesses 210, as already explained above.The first fastening elements 160 are arranged in the first housing part 110 and the second housing part 130 corresponding to one another, so that the first fastening elements 160 engage with one another or interact when the first housing part 110 and the second housing part 130 can be or are mounted together to form the device 100. Thus, the first fastening elements 160 of the first housing part 110 can be designed as latching hooks 210. The first fastening elements 160 of the second housing part 130 can be designed as latching hook recesses 210. The first fastening elements 160 are arranged near the ends of the longitudinal side of the first housing part 110 and the second housing part 130.

[0083] The second fastening elements 170 are shown as circles. They can have the same or comparable designs as the first fastening elements 160. Furthermore, they can also include guide rails 200 or guide and clamping domes and other designs. The second fastening elements 170 are also arranged in the first housing part 110 and in the second housing part 130 (not shown). Alternatively, they can also be arranged in only one housing part. The corresponding fastening elements 170 (not shown) are then arranged in the further housing 180.

[0084] Fig. 4 shows a basic circuit diagram of a device 100 according to the first aspect in a supplementary exemplary embodiment. The device 100 shown comprises second fastening elements 170, which are designed as guide rails 200 and alternatively or additionally as locking lugs 220. The locking lugs 220 are shown as angles. The guide rails 200 and locking lugs 220 are arranged on a holding plate 190 of the device 100. The holding plate 190 protrudes from the device 100 when the first housing part 110 is mounted with the second housing part 130. The holding plate 190 can be arranged on the first housing part 110. For example, it can form an injection-molded part with the first housing part 110. Alternatively, the holding plate 190 can be arranged on the second housing part 130 and form an injection-molded part with the latter.

[0085] Fig. 5 shows a basic circuit diagram of the device 100 according to the first aspect in another exemplary embodiment.

The locking hooks 210 are shown as angles. The shape of the locking hooks 210 is generally known and will therefore not be further described here.

[0087] Fig. 8 is a schematic diagram of a first housing part 110 of the device 100 according to the first aspect in a further exemplary embodiment. The first housing part 110 comprises a second recess 220 for receiving an electrical fuse. The second recess 220 can be designed such that, in the case of a flat fuse, a slim fuse body can be inserted into the first housing part 110 through the second recess 220. However, the wider and taller fuse head cannot be inserted due to its greater size. The second recess 220 is arranged on a front side of the first housing part 110, so that the second recess 220 remains accessible for operation, i.e., for changing the fuse, even when the device 100 is assembled with the further housing 180.

[0088] Optionally, the first housing part 110 can include a third recess 220 for accommodating a backup fuse. The third recess 220 is arranged next to the second recess 220 on the front side of the first housing part 110 and can have the contour and dimensions of the second recess. A mechanical receptacle for the fuse body of the backup fuse can additionally be incorporated into the first housing part 110 (not shown).

[0089] Further optionally, the first housing part 110 can comprise a fourth recess 240 for receiving electrical contact elements designed for connecting wires. The fourth recess 240 is arranged between the first recess 150 and the second recess 220 on the front side of the first housing part 110. It can also be arranged at a different location on the front side of the first housing part 110. The fourth recess 240 is open at the top. Alternatively, the fourth recess 240 can also be closed on all sides.

[0090] Fig. 9 shows a schematic diagram of the device 100 according to the first aspect in a supplementary exemplary embodiment. The fourth recess 240 and the first recess 150 are arranged in corresponding positions. The fourth recess 240 and the first recess 150 are aligned with each other. In other words, a component, for example, a screw terminal with the same width, can be inserted into the fourth recess 240 and the first recess 150 and thus engage in both recesses simultaneously.

[0091] Fig. 10 shows a schematic diagram of the device 100 according to the first aspect in an additional exemplary embodiment. The first housing part 110 comprises the guide elements 120 for receiving the printed circuit board, which is designed as a groove here, on the side walls and the underside. The further web 140 of the second housing part 130 of the device 100 is designed to stiffen the second housing part 130 in the longitudinal direction and is arranged such that the printed circuit board is prevented from falling out. The further web 140 can be designed to bear against the received printed circuit board. Optionally, it can also be designed as a groove. Alternatively, the further web 140 can also be arranged next to the printed circuit board position, as already explained above. In this case, it at least stiffens the second housing part 130.

[0092] The first housing part can be designed as a housing tray. The second housing part 130 can correspondingly be designed as a housing cover. Furthermore, the first housing part 110 and, alternatively or additionally, the second housing part 130 can optionally be made of plastic, preferably of a plastic suitable for injection molding, as already explained above.

[0093] Fig. 11 is a schematic diagram of a system 300 according to a second aspect. The system 300 for providing electrical energy comprises the device 100 according to the first aspect and optionally the associated exemplary embodiments. The system further comprises a printed circuit board 125 with electrical and / or electronic components, which is arranged in the device 100. An electrical or electronic circuit formed from the printed circuit board 125 and the electrical and / or electronic components can be suitable for different types and parameters of various energy storage devices.

[0095] Known solutions feature a metal battery housing to which an additional metal housing is mounted. A circuit board is attached within this housing. The circuit board is attached to the housing in the upper area of ​​the additional metal housing using three screws. Accordingly, assembly of the additional metal housing requires tools, as fasteners, such as screws, are required, and appropriate screwdrivers must be used.

[0096] This process is complex due to the required components and work steps. The object of the invention can be described as simplifying the assembly process.

[0097] Inventively, the assembly of the printed circuit board is realized without tools. This eliminates the need for the known additional metal housing for the printed circuit board. It is replaced by a plastic housing (device) 100. This is connected to the main battery housing (additional housing) 180 via guide rails 200 and locking lugs 220. Depending on the design, one or more printed circuit boards can be arranged in the plastic housing (device) 100. These printed circuit boards are held in position via guide elements 120, whereby the guide elements 120 can be designed as guide rails 200 on the sides and via upstanding webs. Depending on the design, in addition to a fuse that can be inserted from the outside through the second recess 220 and a connection terminal that can be arranged in the fourth recess 240, there is also space for an additional parking position for a reserve fuse, designed as a third recess 230.This has no electrical connection and serves only to store the backup fuse. To protect the circuit board 125 from dirt, moisture, and falling out, a second housing part (housing cover) 130 is mounted to the plastic housing (device) 100 using fastening elements, for example, in the form of locking lugs 220. This has a recess 150 for connecting the circuit board to the battery blocks via connecting cables.

[0098] Many advantages of the present invention are apparent from the foregoing description beyond the specific embodiments, and it will thus be apparent to those skilled in the art that various changes in form, construction, materials, and arrangement of elements are possible within the scope of the invention. Consequently, the invention is not limited to the disclosed embodiments, but includes all embodiments falling within the scope of the appended claims.
