Description
Technical Field
The invention relates to a multipart sealing device for sealing a busbar, in particular a busbar for an on-board electrical system of a motor vehicle, relative to a housing. The invention further relates to a busbar arrangement, in particular for an on-board electrical system of a motor vehicle.
Background
Busbars are frequently used in the automotive field. The large cross-section and solid material make this busbar generally relatively robust in shape. If this busbar is introduced, for example, into a power electronic component or the like and is to be sealed with a conventional sealing arrangement relative to the housing, the sealing arrangement can be pressed open significantly due to the rigidity of the busbar and the forces occurring, so that there is the possibility that the sealing lip of the sealing arrangement is lifted, for example, at the location of the housing wall to be sealed and the sealing location is not sealed.
In contrast to screw contacts, busbars, in particular busbars with plug contacts, are subject to dynamic movements, such as vibrations, tensile forces and pressure forces. In particular, the clamping forces in the contact region between the busbar, the sealing device and the housing are generally significantly lower than when using a threaded contact. In the automotive sector in particular, forces act on the busbar and the busbar arrangement due to vibrations and heat, which can lead to the sealing device possibly not being sealed.
Disclosure of Invention
The object of the present invention is to provide a sealing device for sealing a busbar against a housing, which sealing device makes possible a particularly reliable sealing of the busbar against the housing.
This object is achieved by the multi-part sealing device for sealing a busbar according to the invention.
The multipart sealing device according to the invention for sealing a busbar, in particular for an on-board electrical system of a motor vehicle, against a housing comprises two lateral bearing parts for transmitting mechanical forces between the busbar and the housing. The multipart sealing device furthermore comprises a sealing part which connects the two bearing parts to one another in the transverse direction of the multipart sealing device and has a through-opening for surrounding the busbar on the outer circumference side, and which is designed to rest on the inner contour of the housing. The support part is here made of a material with a higher strength than the sealing part.
In the installed state of the multipart sealing device, the busbar is lowered through the through-opening of the sealing part, wherein the sealing part surrounds the busbar. Furthermore, the through-opening is located on the outer circumference side on the inner contour of the housing, whereby the sealing member also seals reliably in the direction of the housing.
The support part preferably bears laterally and from above and below on the busbar, i.e. preferably rests laterally and from above and below on the busbar. For this purpose, the support part can have, for example, a region in the form of a C which encloses the busbar from below and from above, respectively, and on which the busbar rests laterally. Forces can thereby be borne in all three spatial directions by the support member. The sealing element can thereby be unloaded particularly well. The support part is supported at least on one respective side of the busbar and thus rests on at least the corresponding side of the busbar.
By making the support member from a material having a higher rigidity than the sealing member, the support member can withstand forces particularly well. The support part is here designed to be more rigid than the sealing part. The sealing element is then designed, in particular, to be elastic, so that it can reliably bear against corresponding contours of the housing and the busbar, as a result of which a particularly good sealing effect is achieved.
The multi-part sealing device can be positioned precisely in the housing by means of the lateral bearing parts. The lateral support part has the task of taking up, in particular, tensile forces, so that the sealing part is relieved of load in terms of tensile forces. The multipart sealing device is designed in such a way that preferably all forces occurring at the busbar are captured or absorbed by the bearing part of the multipart sealing device. The sealing member is thus unloaded, whereby the sealing member can reliably seal the busbar against the housing. The respective contact regions of the sealing element which bear against the housing and the busbar are therefore relieved of load with regard to the forces which occur.
If the multi-part sealing device is mounted on the busbar and the housing, the mounting force can be absorbed by the bearing part of the multi-part sealing device. The multipart sealing device is particularly suitable for reliably sealing a busbar for an on-board electrical system of a motor vehicle relative to a housing, for example a housing of a power electronics system or the like. The multi-part sealing device can also be used for other applications in which a busbar is to be sealed with respect to a housing.
The multipart sealing device thus achieves a functional separation in terms of the forces to be borne and the actual sealing effect. The task of the support element is to transmit forces between the busbar and the housing and thus to unload the sealing element. The actual sealing task is taken over by the sealing element. The multipart sealing device can in particular also be designed to be particularly compact, in particular with regard to its structural height.
An advantageous embodiment of the invention provides that the multi-part sealing device is an injection molded part. In other words, the multi-part sealing device is therefore made of plastic, wherein preferably an injection molding method is used, whereby the multi-part sealing device can be manufactured particularly inexpensively with a high part count. In this case, complex geometries of the multipart sealing device can also be realized with a high number of parts, particularly inexpensively. The multi-part sealing device is preferably designed in one piece or in multiple pieces, so that the installation costs for the installation or assembly of the multi-part sealing device are eliminated. Furthermore, this facilitates the handling of the multipart sealing device when it is mounted on the busbar and on the housing.
A further advantageous embodiment of the invention provides for the sealing part to be made of an elastomer. The sealing element thus has particularly good spring properties and can be brought into particularly good contact with the housing and the busbar, as a result of which a reliable sealing effect can be ensured. It is also possible to make the sealing member of another material. It is essential here that the material has a particularly good sealing function on the one hand and that it can be reliably placed against the contour of the housing and the busbar on the other hand.
In a further advantageous embodiment of the invention, it is provided that the support element is made of polyamide or fiber-reinforced plastic. The mechanical properties of the support element required in terms of the function of the bearing force can thus be well adjusted. In the case of fiber-reinforced plastics, the reinforcing fibers can be oriented such that they can withstand forces particularly well in a well-defined direction, preferably in the longitudinal direction of the multipart sealing device. However, it is also possible to use another material, in particular another plastic, for the support part. It is essential here that the support part has a sufficiently high rigidity and strength in order to be able to reliably and permanently withstand the forces occurring during operation.
According to a further advantageous embodiment of the invention, the support part has at least one latching element on the inside for latching with the busbar. This achieves a form-fitting connection of the bearing part to the busbar, so that the bearing part can be subjected to forces from the busbar, and the sealing part is relieved of load.
A further advantageous embodiment of the invention provides that the support element has at least one latching element on the outside for latching with the housing. This allows the support part to be connected to the housing in a form-fitting manner, thereby enabling a reliable transmission of force from the housing to the support part and thus also from the busbar to the housing via the support part. This also helps to unload the sealing member and to have no or as little force as possible acting on the sealing member.
According to a further advantageous embodiment of the invention, it is provided that the sealing part surrounds the bearing part on the outside and rests on the housing on the inside. In this way, it is achieved in a reliable manner that the sealing part on the one hand surrounds the busbar and on the other hand can rest sealingly on the inner contour of the housing.
In a further advantageous embodiment of the invention, it is provided that the bearing part has elements each projecting inward in the transverse direction with a respective undercut which is filled by the sealing part. A particularly reliable and secure connection between the bearing part and the sealing part is thereby achieved. In particular when the multipart sealing device is mounted on a busbar, it can thus be ensured that the sealing part cannot be moved away in an undesired manner relative to the bearing part.
A further advantageous embodiment of the invention provides that the elements each have a film hinge which allows widening of the elements together with the sealing parts when the multipart sealing device is applied to the busbar. The sealing part can thus be deformed or rotated when covering the busbar, whereby the multi-part sealing device can be mounted on the busbar in a simple and reliable manner.
According to a further advantageous embodiment of the invention, it is provided that the sealing component has at least one sealing lip on the inner circumferential side and on the outer circumferential side. Preferably, the sealing member has a plurality of such sealing lips. The sealing lip helps to ensure that the multi-part sealing device, in particular the sealing part, ensures a reliable seal with respect to the housing and the busbar.
In a further advantageous embodiment of the invention, it is provided that the sealing part has a further through-opening for surrounding a further busbar on the outer circumference side, wherein two through-openings are arranged one above the other in the height direction of the multipart sealing device or next to one another in the transverse direction of the multipart sealing device. In the latter case, the busbars may also be arranged, for example, highly fixedly. It is thus achieved that two busbars, for example a plurality of busbars, so-called multi-busbars, can also be received and sealed relative to the housing by the multipart sealing device. If necessary or depending on boundary conditions, it is also possible for the sealing part to have more than two through openings, so that two busbars, in particular two busbars, can be received by the sealing part and thus also by the multipart sealing device in order to seal the busbars with respect to the housing.
The bus bar arrangement according to the invention, in particular for an on-board electrical system of a motor vehicle, comprises the multipart sealing device according to the invention or an advantageous embodiment of the multipart sealing device according to the invention, wherein the sealing parts of the multipart sealing device surround the bus bar on the outer circumference, in particular for an on-board electrical system of a motor vehicle, and rest on the inner contour of a housing in which the bus bar is introduced, wherein the lateral bearing parts of the multipart sealing device are connected to the bus bar and the housing in a form-fitting manner.
An advantageous embodiment of the busbar arrangement provides that the housing has, on its longitudinal sides, corresponding spring elements with receiving openings into which the lateral bearing parts of the multipart sealing device engage in a form-fitting manner. The spring element can be widened when the busbar arrangement is mounted on the housing and can snap back when a certain arrangement of the multipart sealing device is reached, in order to thereby form a latching connection with the lateral bearing part of the multipart sealing device. In this way, a precise fixing of the multipart sealing device in or on the housing can be achieved. Furthermore, it is thereby also possible to achieve that the forces from the housing are reliably received by the support part and therefore the sealing part can be relieved of load.
In addition, a further advantageous embodiment of the busbar arrangement provides that the busbar has a recess on its longitudinal side, into which a bearing part of the multipart sealing device engages in a form-fitting manner. When the multipart sealing device is mounted on a busbar, the respective latching elements of the bearing part can be brought into a snap-fit connection with the recesses on the longitudinal sides of the busbar. By means of the form fit between the busbar and the bearing part, it is possible in a reliable manner to take up forces from the busbar by the bearing part and thus to unload the sealing part.
Finally, a further advantageous embodiment of the busbar arrangement provides that the housing engages on the outside against the region of the bearing part which is in positive fit in the recess. The respective region of the support element can therefore not be opened again after installation in the housing, since the respective side wall of the housing presses against this region. The support part is thus blocked in this region by the housing. It is thus ensured that the latching connection between the bearing part and the busbar can no longer be released when the multipart sealing device has been arranged in the housing.

Detailed Description
Fig. 1 shows a perspective representation of a bus bar device 10 for an on-board electrical system of a motor vehicle. For example, the housing 12 for the power electronics is shown in a cut-away view. The busbar 14 is introduced into the housing 12 and is connected with the contact 16 within the housing 12. A multi-part sealing device 18 is arranged in the housing 12, which multi-part sealing device 18 is only partially visible.
The multipart sealing device 18 serves on the one hand to seal the busbar 14 against the housing 12; on the other hand, the multipart sealing device 18 is also subjected to forces, in particular tensile forces, and reliably transmits forces between the busbar 14 and the housing 12.
The bus bar device 10 is illustrated in fig. 2 without the housing 12. It is well visible in this illustration how the uninsulated conductive core 20 is conductively connected to the contact 16. The connection can be achieved, for example, by laser welding or another method. The electrically conductive core 20 is preferably manufactured from aluminum, so that the busbar 14 can be designed relatively inexpensively and with low weight. However, other materials may be used for the core 20, provided that the material has sufficiently good conductive properties.
The multipart sealing device 18 comprises two lateral bearing parts 22 for transmitting forces between the busbar 14 and the housing 12, which is not illustrated here. Furthermore, the multipart sealing device 18 comprises a sealing part 24 which connects the two bearing parts 22 to one another in the transverse direction, i.e. transversely to the main direction of extension of the busbar 14. The sealing part 24 surrounds the busbar 14 on the outer circumferential side, since the busbar 14 has been pushed through a through-opening of the sealing part 24, which is not labeled here in detail. Furthermore, the sealing member 24 is configured to rest on the inner contour of the housing 12 such that the sealing member 24 reliably seals the busbar 14 with respect to the housing 12.
The support part 22 is here made of a stronger material than the sealing part 24. Preferably, the support part 22 is made of polyamide or of fibre-reinforced plastic. It is critical for the support part 22 to have sufficient rigidity and strength to be able to reliably receive and transmit the forces occurring between the busbar 14 and the housing 12, so that the sealing part 24 is relieved of, in particular, tensile loads. It is particularly critical for the sealing part 24 that the sealing part 24 has sufficient elasticity so that the sealing part 24 can be placed against the busbar 14 and the inner contour of the housing 12 in order to achieve a reliable sealing effect. The sealing member 24 may be made of, for example, an elastomer.
Preferably, the multi-part sealing device 18 is an injection molded part, which is manufactured in a two-component injection molding process. The multi-part sealing device 18 is therefore preferably designed in one piece or in multiple pieces. By means of the injection molding method, the multipart sealing device 18 can be produced in a high number of parts and particularly inexpensively even in geometrically complex forms.
The support part 22 has corresponding latching elements 26 on the inside, which latching elements 26 serve to latch with the busbar 14, specifically with the conductor core 20, in a form-fitting manner. The bus bars 14, in particular the cores 20, which are uninsulated and introduced into the housing 12, each have a recess 28 on their longitudinal sides, into which recesses 28 the latching elements 26 engage in a form-fitting manner. Thereby, the busbar 14 can be accurately positioned relative to the multipart sealing device 18. Furthermore, the positive connection ensures that the connection between the busbar 14 and the latching element 26 is such that forces, in particular tensile forces, can be reliably absorbed from the bearing part 22, as a result of which the sealing part 24 is relieved of load.
The support element 22 furthermore has corresponding latching elements 30 on the outside for latching with the housing 12. In order to produce the latching connection between the latching elements 30 of the bearing part 22 and the housing 12, the housing 12 has corresponding spring elements 32 with receiving openings on its longitudinal sides, into which the latching elements 30 of the lateral bearing part 22 can engage or sink in a form-fitting manner. As a result, the housing 12 can be positioned precisely relative to the multipart sealing device 18. Furthermore, the form-fitting latching between the latching element 30 and the spring element 32 ensures that forces, in particular tensile forces, can be transmitted between the housing 12 and the bearing part 22, thereby unloading the sealing part 24. By being mounted in the housing 12, the latching element 26 is furthermore pressed and fixed by the housing 12 onto the recess 28. After the latching element 30 latches into the spring element 32, the busbar 14 is securely and reliably connected to the housing 12. The busbar 14 is no longer movable within the housing 12.
Fig. 3 shows the busbar arrangement 10 in a further perspective view, wherein the sealing part 24 is also not shown in addition to the housing 12. The support part 22 has a respective element 34 projecting inwards in the transverse direction, which element 34 is provided with a respective undercut 36, which undercut 36 is filled by the sealing part 24, which is not illustrated here. A reliable and secure connection between the sealing part 24 and the lateral support part 22 is thereby achieved.
The sealing elements 34 each have a film hinge 38, which film hinge 38 allows the element 34, according to the present illustration, to widen upward together with the sealing part 24, so that the multipart sealing device 18 can be applied to the busbar 14 without difficulty. If the bus bar 14 is thus introduced into the multi-part sealing device 18, the multi-part sealing device 18 can be rotated or widened in this region and applied to the bus bar 14 as a result of the film hinge 38. When the required length is reached, the bus bar 14 then latches with its recess 28 with the latching element 26. In particular, the bus bar 14 is fixed in its proper arrangement on the multipart sealing device 18.
The multi-part sealing device 18 is illustrated separately in a perspective view in fig. 4. The seal member 24 has a seal lip 40 surrounded on the inner and outer circumferential sides. This sealing lip is responsible for reliably sealing the multi-part sealing device 18, precisely the sealing part 24, against the housing 12 and against the busbar 14. The already mentioned through opening 42 of the sealing element 24 is visible in this illustration. The bus bar 14 can be moved through this through opening 42 until the bus bar 14 has reached its proper arrangement relative to the multipart sealing device 18.
The busbar 14 can be moved through the through opening 42 in the longitudinal direction x of the multipart sealing device 18. The busbar 14 is then surrounded by the sealing part 24 in the transverse direction y and the height direction z of the multipart sealing device 18. The through-opening 24 is formed and dimensioned such that, in a defined arrangement of the busbar 14, the sealing lip 40 running on the inner circumference rests on the busbar 14 or presses against the busbar 14, so that the sealing lip 40 achieves a reliable sealing effect.
Fig. 5 shows the busbar arrangement 10 in a plan view, the housing 12 not being shown. In this illustration, the multi-part sealing device 18 mounted on the busbar 14 is again well visible. A secure latching between the busbar 14 and the multipart sealing device 18 is achieved by the depression 28 on the electrically conductive core 20 of the busbar 14 and the inwardly projecting latching element 26 of the bearing part 22.
Fig. 6 shows the busbar arrangement 10 in a further plan view, wherein only the underside of the housing 12 shown in section is shown, so that the housing interior is exposed and visible. After the multi-part sealing device 18 is mounted in the housing 12, the multi-part sealing device 18 is fixed by the cooperation of the latching element 30 and the spring element 32. When the multipart sealing device 18 together with the bus bar 14 mounted therein is pushed into the housing 12, the spring element 32 with a receiving opening, not shown in detail, can be widened laterally. As soon as the multipart sealing device 18 has reached its proper position, the spring element 32 snaps back inward, so that the latching element 30 is inserted through the receiving opening of the spring element 32. The latching elements 26 can furthermore not be opened again after installation in the housing 12, since the respective end wall of the housing 12 presses against the latching elements 26. The latching element 26 is thus latched by the housing 12.
The detent element 30 and the spring element 32 provide a precisely fitting positioning of the multipart sealing device 18 relative to the housing 12. Furthermore, the latching element 30 and the spring element 32 ensure that forces, in particular tensile forces, are reliably transmitted from the housing 12 to the multipart sealing device 18 and vice versa, wherein the force-bearing action on the one hand of the multipart sealing device 18 takes place at least substantially exclusively via the lateral bearing part 22, on which bearing part 22 the latching element 30 is formed.
Fig. 7 shows a second possible embodiment of the multipart sealing device 18 in a perspective view. The sealing part 24 has in this case two through openings 42, so that the two busbars 14 can be surrounded on the outer circumference by the through openings 42. The two through openings 42 are arranged one above the other in the height direction z of the multipart sealing device 18. In order to be able to securely fasten the two busbars 14 to the multipart sealing device 18, the lateral bearing part 22 has two latching elements 26 on each longitudinal side for latching with the respective busbar 14. Otherwise, the multi-part sealing device 18 is at least substantially identical in construction to the first embodiment of the multi-part sealing device 18.
By means of the multi-part sealing device 18 explained, it is possible to reliably seal one or more busbars 14 in a reliable manner with respect to the housing 12, for example with respect to the housing of a power electronics system or the like. In this case, the functional separation is achieved by the lateral support part 22 taking up the actual mechanical load, the sealing part 24 taking up the actual sealing action in an at least substantially non-load-bearing manner.
The lateral support element 22, which is made of a material having a higher strength than the sealing element 24, is here in particular responsible for relieving the sealing element 24 of the tensile load. All forces occurring at the busbar 14 or at a plurality of busbars 14 are at least substantially absorbed or intercepted by the lateral support elements 22. A secure fixing and positioning of the busbar 14 or busbars 14 and also of the housing 12 relative to the multipart sealing device 18 is furthermore achieved by the lateral bearing part 22. In particular in the automotive sector, in which vibrations, tensile forces and pressure forces occur, a permanent sealing of the busbar 14 or busbars 14 against the housing 12 is achieved in a reliable manner by the multi-part sealing device 18 explained.
