Description

Technical Field

[0001] The invention relates to an adapter assembly for the gas-tight conduction of electric current into a gas container. The invention also relates to a component assembly comprising a gas container and an adapter assembly for supporting the gas-tight conduction of electric current into the gas container. Background Art

[0002] The prior art discloses the use of electric heating devices for the startup of fuel cell systems, in order to quickly bring the fuel cell system, particularly the fuel cell stack of the fuel cell system, to the desired operating temperature. Electrically heated metal catalysts are referred to as heating devices. They have a catalyst housing containing catalyst material that can be quickly brought to the desired operating temperature by means of an electrically powered auxiliary device. The current for the auxiliary device, which is positioned in the catalyst housing, is conducted into the catalyst housing via a current connection protruding from the catalyst housing. However, practice has shown that the sealing mechanism on the current connection, which is used to prevent gas from escaping the catalyst housing during the functional operation of the catalyst, does not meet the desired requirements. Specifically, gas leakage in the area of ​​the current connection can be determined in various tests. Summary of the Invention

[0003] The object of the present invention is to at least partially address the above-mentioned problems. In particular, the object of the present invention is to provide an auxiliary device for the gas-tight conduction of electric current into a gas container, in particular in the form of a metal catalyst as described in the introduction.

[0004] The aforementioned objects are achieved, in particular, by the adapter assembly and the component assembly according to the present invention. Further advantages of the present invention are apparent from the description and the accompanying drawings. Features and details described herein with respect to the adapter assembly are of course also applicable in conjunction with the component assembly according to the present invention, and vice versa. Therefore, reference is always made to the disclosure of certain aspects of the invention, or reference can be made to each other.

[0005] According to a first aspect of the present invention, there is provided an adapter assembly for gas-tightly conducting current into a gas container, wherein the gas container includes a protruding current terminal extending from an interior cavity of the gas container through an exterior surface of the gas container for conducting current into the gas container. The adapter assembly comprises:

[0006] a housing for at least partially surrounding the current connection terminal in its circumferential direction, wherein the housing comprises a cover with a through-opening for the contactless passage of the current connection terminal through the housing,

[0007] - a container sealing mechanism for gas-tightly securing the housing to the gas container,

[0008] - a support mechanism for fixing the current connection terminal in the housing,

[0009] - a first insulating member for being positioned at least partially within the housing between the support mechanism and the cover to achieve electrical insulation between the support mechanism and the cover,

[0010] - a housing sealing mechanism for being fixed to a current connection terminal extending from the housing to seal a gap between the current connection terminal and the cover, and

[0011] A second insulating member is arranged to be positioned at least partially outside the housing between the housing sealing means and the cover to achieve electrical insulation between the housing sealing means and the cover.

[0012] The adapter assembly according to the present invention allows for the gas-tight conduction of electric current into a gas container in a simple and reliable manner. This means that gas is prevented from escaping from the gas container through the adapter assembly into the gas container environment during the conduction of electric current into the gas container. The gas container may be an electrically heated catalyst, particularly a metal catalyst, such as the catalyst housing of an Emicat.

[0013] The adapter assembly according to the present invention can be produced using simple means. In addition to standard components, simple geometric objects, such as a simple hollow cylinder of the housing, can be used to produce the adapter assembly. This allows for quick and inexpensive production. Furthermore, the adapter assembly can be implemented in a relatively small space.

[0014] The housing may include a housing cover portion that at least partially extends around the current connection terminal like a shroud. The housing cover portion is preferably cylindrical and / or tubular. The housing at least partially surrounding the current connection terminal may mean that the housing and / or the housing cover portion only extend around a portion of the current connection terminal in the longitudinal direction. The housing being designed to at least partially surround the current connection terminal in the circumferential direction may mean that the housing surrounds the current connection terminal in the longitudinal direction in the form of a sheath.

[0015] In addition to the housing cover described above, the cover is preferably designed as a disk and / or plate with a preferably centrally formed through-hole. Particularly preferably, the housing cover and the cover can be provided as components materially connected to each other at at least one location. This simplifies the installation of the adapter assembly on the gas container.

[0016] Leading the current connection terminal out of the housing in a contactless manner means leading the current connection terminal out of the housing without direct mechanical contact between the current connection terminal and the housing. Since the current connection terminal and the housing are preferably made of metal and / or conductive material, short circuits and / or other electrical faults can be prevented.

[0017] The diameter and / or the size of the through-hole are respectively selected to be larger than the diameter and / or the size of the current connection terminal present and / or desired in the region of the through-hole.

[0018] A container sealing mechanism may be a component for connecting the outer shell to the gas container by material bonding. The container sealing mechanism preferably comprises a weld seam, by which the outer shell is secured to the gas container, in particular at least to the outer surface of the gas container. Preferably, the container sealing mechanism provides a region for securing the outer shell to the gas container in a gas-tight manner. In other words, the container sealing mechanism does not necessarily seal the entire container in a gas-tight manner.

[0019] The support mechanism serves to secure the first insulating component in the desired position. The support mechanism can thus be understood as a counter-support for the cover, more precisely, a counter-support on the inner side of the cover facing the interior of the housing. To position the first insulating component, the support mechanism can be positioned directly on the first insulating component, preferably with direct surface contact between the support mechanism and the first insulating component.

[0020] Sealing the gap can refer to the airtight closure of at least one gap between the current connection terminal and the cover, where the gap arises from the contactless passage of the current connection terminal from the housing via the through-hole. In other words, the housing sealing mechanism is preferably designed to prevent gas from escaping from the housing. This can be done directly or indirectly. Thus, the housing sealing mechanism can hermetically seal the gap directly or through auxiliary means, such as a second insulating component.

[0021] The first insulating part and the second insulating part can each have a disk-shaped insulating ring or be designed as a disk-shaped insulating ring so as to be arranged in a ring around the current connection terminal.The first insulating part and / or the second insulating part can each be designed to seal the container to prevent gas from escaping the housing.

[0022] The first insulating component and / or the second insulating component can be made of or comprise a corresponding elastic plastic. The first sealant and / or the second sealant are preferably designed as a single piece. However, in a preferred embodiment, the insulating component can also be made of a dimensionally stable, non-conductive material such as ceramic, or at least comprise such a material for its electrical insulation function.

[0023] According to another embodiment of the present invention, it is possible that in the adapter assembly, the current connection terminal can have a first current connection terminal threaded portion, and the support mechanism can have at least one nut for screwing onto the first threaded portion. The support mechanism can thus be provided particularly simply and inexpensively. The support mechanism preferably has two nuts, one of which serves as a lock nut. Screwing can be understood as screwing on, screwing in, or screwing on. The threaded portion can therefore have an external or internal thread. The first current connection terminal threaded portion is preferably designed as an internal thread on the inner circumference of the support mechanism and / or the at least one nut, or has an internal thread that can be screwed onto a corresponding external thread of the current connection terminal.

[0024] It is also possible that, in the adapter assembly according to the present invention, the current connection terminal may have a second current connection terminal threaded portion, and the housing sealing mechanism may have at least one nut for screwing onto the second threaded portion. In other words, the nut can be screwed onto the second threaded portion. This allows for a relatively simple and inexpensive design of the adapter assembly. The at least one nut of the housing sealing mechanism can, for example, be screwed onto the second insulating component until a hermetic seal is achieved for sealing the housing. The housing sealing mechanism may have another nut that serves as a lock nut and is screwed onto the second current connection terminal threaded portion to secure the first nut of the housing sealing mechanism.

[0025] It may further be advantageous if the adapter assembly according to the invention has a clamping mechanism which is at least partially arranged or arrangeable between the support mechanism and the first insulating component in order to press the first insulating component in the direction of the cover.

[0026] Thus, it is possible to simply position the first insulating component on the cover, or more precisely, on the inner side of the cover, at a desired position. The clamping mechanism can have an integrated spring element. The clamping mechanism is preferably designed in an annular shape so that it can be moved onto the current connection head. The adapter assembly according to the present invention can also have at least one annular washer for positioning between the support mechanism and the first insulating component, between the housing sealing mechanism and the second insulating component and / or between the support mechanism and the clamping mechanism and / or between the clamping mechanism and the first insulating component. Thus, force can be simply, reliably and effectively transmitted to the respective components in an inexpensive and safe manner. Here, the annular shape preferably refers to a shape formed by two concentrically arranged hoods with a circular cross-section. The outer circumference and / or inner circumference of the annular shape of the present invention can also be designed in an elliptical and / or angular shape, such as the hexagonal shape of a nut. The insulating components are preferably designed in a disc shape, that is, with a flat or substantially flat top surface and a flat bottom surface.

[0027] According to another embodiment of the present invention, the adapter assembly comprises an elastically deformable first current-conducting component with a current-conducting component fastening portion for securing the first current-conducting component to the current connection head outside the housing to tap current from the current connection head through the first current-conducting component. Thermally induced dimensional differences in the gas container, the current connection head, and / or the housing can be easily and cost-effectively compensated for by the first current-conducting component. The current-conducting component fastening portion preferably comprises a current-conducting component thread, in particular an internal thread in and / or on the current-conducting component, for screwing the current-conducting component onto the current connection head.

[0028] The first current conducting component is preferably plate-shaped or substantially plate-shaped. That is, the length and width of the current conducting component are each several times longer and / or taller than its height. Furthermore, the current conducting component preferably has a flat or substantially flat top surface and a flat or substantially flat bottom surface.

[0029] In particular, the current-conducting component can be designed as a cuboid or substantially cuboid with respect to its outer contour.

[0030] Furthermore, the adapter assembly according to the present invention can include a fastening mechanism for at least partially securing the first current-conducting component to the current connection head between the fastening mechanism and the housing sealing mechanism in a non-destructively releasable manner. This fastening mechanism facilitates assembly and disassembly during maintenance and / or repair. In the adapter assembly according to the present invention, it can be advantageous if the current connection head has a second current connection head thread and the fastening mechanism includes at least one nut for screwing onto the second current connection head thread.

[0031] According to another aspect of the present invention, an adapter assembly for airtightly conducting current into a gas container is provided, wherein the gas container includes a protruding current terminal extending from an interior cavity of the gas container through an exterior surface of the gas container for conducting current into the gas container. The adapter assembly includes:

[0032] a housing for at least partially surrounding the current connection terminal in the circumferential direction of the current connection terminal, wherein the housing has a cover with a through-opening,

[0033] a connecting piece having a connecting piece fastening portion for fastening the connecting piece to the current connection head for electrical contact between the current connection head and the connecting piece and for conducting current into the gas container via the connecting piece and through the current connection head, wherein the through-opening is designed for leading the connecting piece fastened to the current connection head out of the housing without contact,

[0034] - a container sealing mechanism for gas-tightly securing the housing to the gas container,

[0035] - a supporting mechanism fixed to the connecting element within the housing,

[0036] a first insulating member, which is positioned at least partially between the support mechanism and the cover within the housing for electrical insulation between the support mechanism and the cover,

[0037] - a housing sealing mechanism, which is fixed to the portion of the connector that passes through the housing and is used to seal the gap between the connector and the cover, and

[0038] A second insulating component is located outside the housing at least partially between the housing sealing mechanism and the cover for electrical insulation between the housing sealing mechanism and the cover.

[0039] The adapter assembly according to this aspect essentially corresponds to the embodiment according to the first aspect, with the housing being sealed not around the current connection but around the connection piece. This has the advantage that the adapter assembly can be used and / or mounted more easily and / or flexibly on various gas containers and / or current connection pieces. The features described above with respect to the adapter assembly in the housing region, and in particular in the region of the through-hole, on the current connection piece, apply analogously to the adapter assembly according to the second aspect and with respect to the connection piece.

[0040] For example, in the adapter assembly according to the second aspect, it is possible that the connector has a first connector threaded portion, and the support mechanism has at least one nut for screwing onto the first threaded portion. It is also possible that the connector has a second connector threaded portion, and the housing sealing mechanism has at least one nut for screwing onto the second connector threaded portion.

[0041] The adapter assembly with the connecting element can also have a clamping mechanism, which is at least partially arranged between the supporting mechanism and the first insulating component in order to press the first insulating component in the direction of the cover.

[0042] The elastically deformable first current conducting component may include a current conducting component fastening portion for securing the first current conducting component to the connecting member outside the housing to tap current from the connecting member through the first current conducting component. The securing mechanism may be at least partially disposed between the securing mechanism and the housing sealing mechanism to secure the first current conducting component to the connecting member in a non-destructively detachable manner.

[0043] Furthermore, in the adapter assembly according to the second aspect, it is possible that the connector has a second connector threaded portion, and the fixing mechanism has at least one nut for screwing onto the second connector threaded portion. The connector fastening portion may include a third connector threaded portion for screwing the connector onto a corresponding current connection threaded portion of the current connection terminal. Thus, the connector assembly can be quickly, easily, and reliably connected to the current connection terminal. The third connector threaded portion preferably has an internal thread that can be screwed onto a corresponding external thread of the current connection terminal.

[0044] According to another embodiment of the present invention, in the adapter assembly according to the second aspect, the connecting element is designed as a single piece, in particular as a pin and / or journal. Thus, the adapter assembly can be provided in a particularly stable, space-saving and cost-effective manner.

[0045] It may be further advantageous that, in the adapter assembly according to the present invention, the connecting piece has a fourth connecting piece threaded portion on one end face of the connecting piece for threaded connection between another current terminal and the connecting piece.

[0046] Thus, the current connection section for connecting a further current connection terminal to the connecting piece outside the housing can be realized in a simple, space-saving manner.

[0047] The adapter assembly of the present invention also includes an elastically deformable second current-conducting component, wherein the current connection head and the connecting piece are mechanically connected to each other via the second current-conducting component for electrical connection between the current connection head and the connecting piece. Thermally induced dimensional differences in the gas container, the current connection head, the connecting piece, and / or the housing can be compensated for simply and cost-effectively via the second current-conducting component. The second current-conducting component preferably includes a first current-conducting component threaded portion and / or a second current-conducting component threaded portion, each of which in particular includes an internal thread in and / or on the second current-conducting component. The second current-conducting component can be easily connected to the current connection head and / or the connecting piece via the threaded portion to establish the desired electrical connection between the current connection head, the second current-conducting component, and the connecting piece.

[0048] The second current conducting component is preferably plate-shaped or substantially plate-shaped. Furthermore, the second current conducting component preferably has a flat or substantially flat top surface and a flat or substantially flat bottom surface. The current conducting component can be designed as a cuboid or substantially cuboid, particularly with respect to its outer contour.

[0049] According to another aspect of the present invention, a component assembly is provided. The component assembly includes a gas container having an outer surface and a protruding current connection terminal, wherein the current connection terminal extends from an interior of the gas container through the outer surface of the gas container for conducting current into the gas container. Furthermore, the component assembly includes an adapter assembly, as described in detail above, secured to the outer surface and the current connection terminal.

[0050] The component combination according to the invention thus offers the same advantages as those explicitly described with respect to the adapter assembly according to the invention. The current connection terminal is preferably designed in the form of a pin and / or a journal. BRIEF DESCRIPTION OF THE DRAWINGS
