Description

[0001] Electrical appliance, especially inverter

[0002] Description:

[0003] The invention relates to an electrical device, in particular an inverter.

[0004] It is generally known that a cable gland, in particular a PG gland, is used in electrical appliances.

[0005] From DE 102013102521 A1, an operating and display device for an electrical device is known as the closest prior art.

[0006] The invention is therefore based on the objective of further developing an electrical device with a high degree of protection in a simple manner.

[0007] According to the invention, the problem is solved in the electrical device according to the features specified in claim 1.

[0008] Important features of the invention in the electrical device, in particular the inverter, are that the electrical device has a base part that functions as a housing part for an interior area of ​​the electrical device,

[0009] wherein the electrical appliance comprises a base part functioning as a housing part for an interior area of ​​the electrical appliance, and a lid part as well as a cover, in particular a cover part,

[0010] wherein the lid part and the cover, together with the base part, enclose and / or surround the interior area to form a housing,

[0011] a sealing strip is incorporated in the interior area,

[0012] wherein the lid part rests against a first sealing surface provided by the base part and the sealing rib, or wherein the base part and the sealing rib rest against a first sealing surface provided by the lid part,

[0013] ISI \ EIDOPAT 23.02.2026 wherein the aperture rests against a second sealing surface provided by the base part and the sealing rib or wherein the base part and the sealing rib rest against a second sealing surface provided by the aperture.

[0014] An advantage of this design is that the cover and the panel are sealed against the base. The sealing surfaces are continuous and uninterrupted, even though the sealing rib only provides or contributes to a portion of the respective sealing surface.

[0015] In particular, the sealing rib connects directly to the sealing surface of the base part, thus preventing gaps. In this way, the sealing surface remains uninterrupted, even though different components contribute to it.

[0016] It is also important that the first sealing surface is spaced apart from the second sealing surface. Furthermore, the first sealing surface surrounds an opening in the base part that is covered by the cover part, and the second sealing surface surrounds an opening in the base part that is covered by the cover plate. The sealing rib divides the total opening of the base part into the two openings.

[0017] In an advantageous embodiment, a first inclined surface is formed on the base part, particularly on a particular intermediate wall, against which a first end region of the sealing rib rests, and a second inclined surface is formed against which a first end region of the sealing rib rests. It is advantageous that the sealing rib rests with its two end regions on two bearing surfaces, namely the inclined surfaces. When the cover part and the cover plate are mounted, the sealing rib is pressed further and further towards the bearing surfaces and thus seals reliably.

[0018] In a particularly advantageous embodiment, a projecting support dome area is formed centrally between the inclined surfaces of the base part, which supports the sealing rib. The advantage of this is that a more uniform distribution of the contact force can be achieved, thus preventing sagging of the sealing rib.

[0019] In an advantageous embodiment, the distance between the inclined surfaces increases with decreasing distance to the first or second sealing surface, in particular where the distance is always measured in a plane that is aligned parallel to the first or second contact surface. It is advantageous that when the sealing rib is pressed against the inclined surfaces, the sealing rib is continuously deformed elastically, thus ensuring a reliable seal and achieving a high degree of protection.

[0020] In an advantageous embodiment, a tab area is formed on the sealing rib and the tab area protrudes from the sealing rib, wherein a screw protrudes through the tab area, the threaded section of which is screwed into a threaded bore provided in a thickening of the base part and / or in a dome-like elevation of the base part.

[0021] In particular, the screw head presses the tab area against the thickening or dome-like protrusion. An advantage of this is that the sealing ridge can be positioned precisely.

[0022] In an advantageous embodiment, the first sealing surface is annular and / or the second sealing surface is annular. It is advantageous that the cover part and the aperture are each sealed at their outer circumference towards the base part.

[0023] In an advantageous embodiment, leg areas protrude from the sealing rib, which project into a respective groove of the base part.

[0024] In particular, each section terminates in a sloping surface. A key advantage is that the sealing strip is guided when placed on the sloping surfaces and can therefore be inserted by simply pushing it in. This guided movement ensures a reliably high level of protection.

[0025] In an advantageous embodiment, the first and second sealing surfaces extend parallel to each other along the sealing rib. It is advantageous that the sealing rib extends in a rod-like and / or straight manner between the two inclined surfaces, thus ensuring that the two sealing surfaces run parallel to each other on the sealing rib.

[0026] In an advantageous embodiment, the sealing web comprises a base body made of a first plastic and a seal made of a second plastic, in particular a multi-part seal, wherein the second plastic has a higher elasticity than the first plastic and / or wherein the base body has a structure of intersecting stiffening ribs. It is advantageous that the sealing web has high stiffness and the seal is nevertheless elastically deformable with low forces, thus fitting tightly against the sealing surface. The high stiffness is achieved, in particular, by selecting a less elastic material and by the intersecting stiffening ribs.

[0027] In an advantageous embodiment, the respective inclined surface is flat, and the direction of the normal to the flat inclined surface forms an angle of 25° to 65° with the direction of the normal to the first or second contact surface. The advantage here is that the inclined surfaces enable secure positioning of the sealing rib.

[0028] In an advantageous embodiment, the electrical device has a component, in particular a maintenance switch, arranged in a housing.

[0029] wherein the housing has a lower part and an upper part placed on the lower part,

[0030] wherein the lower part has a hollow receiving area into which a pin area projecting into a continuous recess of the base part is inserted,

[0031] In particular, the continuous recess is essentially rectangular and / or the hollow receiving area projects through the continuous recess. An advantage of this design is that a detachable and secure attachment of the housing to the base part can be achieved. This detachability allows for quick and easy replacement with a different component. A variant of the electrical device without this component can also be manufactured quickly and easily. Thus, a series of electrical devices with a high degree of variation can be produced using only a small number of components.

[0032] In an advantageous embodiment, the housing of the electrical device comprises at least the base part, a lid part mounted thereon, and a cover, in particular a protective cover. It is advantageous that the sealing element is covered by the cover and / or the lid part and is thus arranged between the base part and the cover and / or lid part. In an advantageous embodiment, the hollow receiving area on the lower part protrudes on the side of the lower part facing away from the upper part. It is advantageous that this allows for simple, quick, and secure mounting of the housing.

[0033] In an advantageous embodiment, one or more grooves are formed on the side of the lower part facing away from the upper part.

[0034] wherein one or more projections, each acting as a rail area, are formed on the base part and extend into the groove or grooves,

[0035] In particular, the hollow receiving area is arranged between the two grooves. An advantage of this is that a secure fastening is possible.

[0036] In an alternative advantageous embodiment, one or more elevations, each functioning as a rail area, are formed on the side of the lower part facing away from the upper part.

[0037] wherein one or more grooves are formed on the base part into which the projections extend,

[0038] In particular, the hollow receiving area is arranged between the two protrusions. An advantage of this is that secure fastening is possible.

[0039] In a preferred embodiment, the groove or grooves extend parallel to the insertion direction of the pin area into the hollow receiving area. This offers the advantage of a secure fastening.

[0040] In an advantageous embodiment, the raised section(s) acting as rail sections extend parallel to the groove(s). This design offers the advantage of achieving secure fastening.

[0041] In an advantageous embodiment, a half-tube section projects from the lower part, which is inserted into a continuous recess of a sealing element. The advantage here is that a reliable, tight connection can be achieved. In an advantageous embodiment, the tube direction of the half-tube section is aligned parallel to the groove(s) and / or to the rail section(s). The advantage here is that when the housing is inserted, not only the hollow receiving area but also the half-tube section is connected, while the housing is guided by the rail sections engaging in the grooves.

[0042] In an advantageous embodiment, a second continuous recess is formed in an intermediate wall, in particular a wall, which is open towards the lid part and / or the cover, and which is formed on the base part and projects towards the cover part and / or the cover part.

[0043] The sealing element is inserted into the second recess and seals the connection between the half-pipe section and the base section. A key advantage is that the second recess is designed as a wall penetration, allowing electrical cables to pass through the wall. The sealing element ensures a tight and secure seal for these cables.

[0044] In an advantageous embodiment, a bead, in particular a partially circumferential bead, is formed on the intermediate wall at the edge of the second recess, which projects into a groove, in particular a partially circumferential groove, of the sealing element. The advantage here is that the sealing element is securely and tightly fastened.

[0045] In an advantageous embodiment, prominent tab areas are formed on the lower part, each of which projects into a respective recess that is incorporated into the base part and / or that is incorporated into a thickened area of ​​the intermediate wall of the base part.

[0046] wherein the respective tab area rests on the bottom of the respective recess and the recess limits the respective tab area in a direction perpendicular to the groove or grooves. An advantage of this is that the housing is securely attached to the base part by means of the hollow receiving area, which is mounted on the pin area, and the tab areas. In an advantageous embodiment, the respective tab area received in the respective recess is arranged between the cover and the base part. An advantage of this is that the tab area is securely attached.

[0047] In an advantageous embodiment, a threaded bore is provided in the bottom of each recess.

[0048] into which a screw with its respective threaded section is screwed, the screw head of which presses the cover or lid part towards the base part, in particular so that the intermediate tab area is fixed. The advantage here is that a secure fastening can be achieved.

[0049] In a preferred design, the respective screw protrudes through the respective tab area. The advantage here is that a secure fastening can be achieved.

[0050] In an advantageous embodiment, the component is connected to a printed circuit board by means of electrical conductors,

[0051] where the circuit board is mounted in the interior area and / or attached to the base part,

[0052] where the lines protrude through and / or are routed through the half-pipe area,

[0053] In particular, the component is spaced from the circuit board by means of the partition. An advantage of this is that the component can be optionally added or, in another variant, cannot be installed and can therefore be omitted. Thus, a high degree of variance within a series of electrical devices can be achieved with a small number of components.

[0054] In a preferred embodiment, the bead is U-shaped. An advantage of this design is that the sealing element is held securely in place in several directions.

[0055] In an advantageous embodiment, the bead follows the U-shaped edge of the second recess continuously. An advantage of this is that a secure and tight connection between the base part and the sealing part can be achieved. Further advantages arise from the dependent claims. The invention is not limited to the combination of features of the claims. For those skilled in the art, further meaningful combinations of claims and / or individual claim features and / or features of the description and / or the figures will be apparent, in particular from the problem statement and / or the problem arising from a comparison with the prior art. The invention will now be explained in more detail with reference to a schematic illustration:

[0056] Figure 1 shows an electrical device according to the invention, in particular a converter, in an oblique view, wherein a base part 1 of the electrical device is covered by at least a cover part 2 and a cover 5, in particular a cover part, in particular forming a housing, and a maintenance switch 9 is arranged on the electrical device.

[0063] Figure 8 shows a longitudinal section through the area of ​​the electrical device accommodating the maintenance switch 9.

[0064] Figure 9 shows an oblique view of an area of ​​the base part 1 which accommodates a sealing rib 90.

[0065] Figure 10 shows the area without the sealing rib 90 in an oblique view.

[0066] Figure 11 shows the sealing rib 90 in a first oblique view. Figure 12 shows the sealing rib 90 in a second oblique view.

[0067] Figure 13 shows the sealing rib 90 from a third viewing direction in oblique view.

[0068] Figure 14 shows the sealing rib 90 from a fourth viewing direction in oblique view.

[0069] As shown in the figures, the electrical device has a tub-shaped base part 1, onto which the lid part 2 and the cover 5, in particular the cover part, are placed.

[0070] A printed circuit board 54, on which electronic components are mounted, is accommodated in the covered, trough-shaped area of ​​the base part 1, particularly for forming an electronic circuit, especially a converter. The generated thermal power loss can be dissipated to the ambient air via cooling fins formed on the cover part 2 and projecting into the surrounding environment.

[0071] The aperture 5 can either be configured with connector parts (3, 4, 10) of different designs according to Figure 2 or alternatively with connector parts 3 of identical design according to Figure 3.

[0072] With the exception of Figure 3, all figures refer to a first embodiment. The second embodiment is obtained by replacing the aperture 5 shown in Figures 1, 2, and 8 with the aperture shown in Figure 3.

[0073] The base part 1 is connected to the cover 5 and the lid 2, as well as to a maintenance switch 9 and its housing, which consists of a lower part 7 and an upper part 6 mounted on the lower part 7. Specifically, the upper part 6 and the lower part 7 are connected by a clip connection, which ensures the continuous contact of a circumferential seal. This provides a secure and sealed connection. The cover 5 is attached to the base part 1 by screws 8, which are screwed into threaded holes in the base part 1 with their respective threaded sections, and whose screw heads press the cover 5 against the base part 1.

[0074] The threaded holes are inserted into thickened areas of the base part 1.

[0075] The housing of the maintenance switch, specifically the upper part 6 and lower part 7, has prominent tab areas 40 that project between the cover 5 and the base part 1. A screw 8 passes through each tab area, so that when the screw 8 is tightened, the tab areas 40 are detachably connected. The cover 5, pressed towards the base part 1, then presses the tab areas 40 onto the base part 1.

[0076] On its side facing away from the upper part 6, the lower part has a hollow receiving area 71 into which a pin area 51 formed on the base part 1 projects. During assembly, the lower part 7 with its hollow receiving area 71 is thus slid onto the pin area 51.

[0077] This sliding motion is guided by the formation of grooves 70 on the side of the lower part 7 facing away from the upper part 6, parallel to the sliding direction. These grooves run parallel to each other and are positioned on projections formed on the base part 1, which function as rail areas 50, in particular guide rail areas. These projections also extend parallel to the sliding direction and thus enable the guided sliding of the hollow receiving area 71 onto the pin area 51.

[0078] At the same time, a protruding half-pipe area 72 formed on the lower part 7 is inserted into a corresponding, in particular semi-circular, recess of a sealing part 52.

[0079] The sealing part 52 has a partially circumferential groove on its outer circumference, which is pushed onto a bead 60 formed on the base part 1, which is also partially circumferential on an inner side of a recess, in particular a half-window-shaped recess.

[0080] The recess is provided in an intermediate wall of the base part 1, wherein the intermediate wall separates a first interior area of ​​the electrical device, which accommodates the circuit board 54, from a second interior area in which the maintenance switch 9 is arranged.

[0081] The sealing part 52 seals from the half-pipe area 72 to the base part 1.

[0082] Thus, electrical lines can be routed from the maintenance switch 9, i.e., from the area enclosed by the housing formed by the upper part 6 and the lower part 7, to the first interior area through the half-pipe area 72.

[0083] The sealing part 52 is inserted into the recess of the partition wall 55, with the bead 60 projecting into the groove of the sealing part 52 guiding the sealing part.

[0084] The half-pipe section 72 of the lower part 7 is covered by a similarly prominent extension of the upper part 6. Thus, the cables from the maintenance switch to the circuit board 54 are protected as they pass through the partition wall and the sealing element 52.

[0085] The pin area 51 projects into a continuous recess in the base part 1, particularly on the side of the base part 1 facing away from the aperture 5. This recess is continuous through the side of the base part 1 facing away from the upper part 7 and / or the aperture 5 and is preferably rectangular in shape.

[0086] The direction in which the half-pipe section 72 protrudes from the lower part 7, and the extension direction of the grooves 70 and the rail sections 50, and the direction in which the pin section 51 projects into the continuous recess of the base part 1 are all parallel to each other.

[0087] The partition wall 55 has thickenings, each of which has a recess, in the bottom of which a threaded bore is provided for receiving the respective screw 8.

[0088] The recess is open towards the maintenance switch 9, allowing a respective tab area 40 to project into the recess, thus limiting the respective tab area in the sliding direction and in the direction perpendicular to the sliding direction, which is parallel to the side of the lower part 7 facing away from the upper part 6. The sealing part 52 is preferably made of a plastic.

[0089] The upper part 6 and the lower part 7 are preferably each made of plastic, in particular each as a plastic injection molded part.

[0090] The base part 1 is preferably made of metal.

[0091] In further embodiments according to the invention, the sealing part 52 is made of rubber.

[0092] In further embodiments according to the invention, instead of the maintenance switch, another component is arranged in or on the housing formed from the upper part 6 and the lower part 7, in particular a plastic housing, wherein this component is preferably connected to the circuit board 54 by electrical lines.

[0093] In further embodiments according to the invention, only one groove and a raised section functioning as a rail area are formed.

[0094] In further embodiments of the invention, the groove or grooves are formed not on the lower part 7 but on the base part 1, whereas the projections functioning as rail areas 50 are formed on the lower part 7. This reversal, however, does not change the mode of operation, as guidance during insertion remains effective.

[0095] The aperture 5 is positioned next to the cover part 2. Both the aperture 5 and the cover part 2 are sealed to the base part 1 by means of a circumferential gasket. For this purpose, the aperture 5 rests on the base part 1, with a flat gasket or an injection-molded gasket positioned between them.

[0096] The contact surface of the aperture on the base part 1 is preferably a flat surface. The contact surface of the cover part 2 on the base part 1 is preferably a flat surface, which, however, is interrupted.

[0097] The gaps are bridged by a sealing strip 90, which is made of a more elastic material than the base part 1. Preferably, the sealing strip is made of a plastic or rubber material. The cover 5 is pressed onto the sealing strip 90 and thus tightly connected. Likewise, the cover part 2 is pressed onto the sealing strip 90 and thus tightly connected.

[0098] The sealing web 90 itself is placed on inclined surfaces 101 of the base part 1 at both of its end areas, especially when viewed in the direction of the web.

[0099] The inclined surfaces 101 are preferably planar, wherein the directions of the normals of the respective planar inclined surfaces 101 form an angle of less than 180° to each other. In particular, the normals intersect.

[0100] The normals are therefore not parallel to the normal of the printed circuit board plane of the printed circuit board 54, but have an angle of at least 25° and at most 65° to the normal of the printed circuit board plane of the printed circuit board 54.

[0101] The inclined surfaces 101 are preferably formed on thickenings of the base part 1 or on intermediate wall areas of the base part 1.

[0102] In particular, the inclined surfaces 101 are aligned in a mirror-symmetrical manner relative to each other.

[0103] A prominent support dome area 91 is formed centrally between the inclined surfaces 101 on the base part 1, which supports the sealing rib 90. The sealing rib 90 thus bridges a free area and provides a contact surface to the cover part 2 and to the aperture 5. In this way, the sealing rib 90 ensures an uninterrupted sealing surface for the aperture 5 and also for the cover part 2.

[0104] On the sealing rib 90, a tab area 93 protrudes, particularly laterally, through which a screw 92 protrudes, the thread area of ​​which is screwed into a threaded bore of the base part 1 and the screw head of which presses the tab area 93 and thus the sealing rib 90 towards the base part.

[0105] This threaded area is preferably incorporated into a thickening of the base area and / or into a dome-like elevation of the base part 1. Preferably, the intermediate wall raised on the base part 1 has not only the respective inclined surface 101 but also the bead 60 and the recesses into which the threaded bores 53 are provided.

[0106] Preferably, the sealing web 90 has a base body made of a first plastic, to which a seal is bonded, providing the sealing surface and sealing towards the aperture 5 and the cover part 2. In particular, the seal is made of multiple parts and / or of a second plastic that has a higher elasticity than the first plastic.

[0107] The base body of the sealing strip 90 has a stiffening rib structure and two leg sections 111 projecting from the sealing strip 90 towards the base part 1, which extend into corresponding guide grooves of the partition wall. In particular, the leg sections 111 project on the side facing away from the cover part 2 and the cover plate 5. Reference numeral list
