Description

[Technical Field]

[0001] The present invention relates to an adapter mechanism for conducting electrical current into a gas container in a gas-tight manner. The present invention further relates to a component composite having a gas container and an adapter mechanism for supporting the flow-tight conduction of electrical current into the gas container. [Background technology]

[0002] In the prior art, it is known to use an electric heating device for the start-up operation of a fuel cell system in order to bring the fuel cell system, in particular the fuel cell stack of the fuel cell system, to the desired operating temperature as quickly as possible. Electrically heatable metal catalysts are known as heating devices. These have a catalyst housing in which catalytic material is located, and the electrically actuable heating device can quickly bring the catalytic material to the desired operating temperature. Electric current for auxiliary devices positioned within the catalyst housing is conducted into the catalyst housing through current connections protruding from the catalyst housing. In practice, it has been shown that the seals at the current connections to prevent gas leakage from the catalyst housing during functional operation of the catalyst do not meet the desired requirements. Specifically, various experiments have been able to confirm gas leakage in the area of ​​the current connections in each case. Summary of the Invention

[0003] The object of the present invention is to at least partially address the above-mentioned problems, in particular to provide an auxiliary means for conducting electric current gastightly into a gas container, in particular in the form of the metal catalyst mentioned at the beginning.

[0004] The above-mentioned problem is solved by the claims, in particular by an adapter mechanism according to claim 1, an adapter mechanism according to claim 8 and a component complex according to claim 20. Further advantages of the invention become apparent from the dependent claims, the description and the drawings, whereby features and details described in connection with the adapter mechanism are naturally also valid in connection with the component complex according to the invention and vice versa, so that cross-reference is always made or can be made to the disclosure of the individual inventive aspects.

[0005] In a first aspect of the present invention, there is provided an adapter mechanism for conducting electrical current into a gas container in an airtight manner, the gas container including a protrusion-like electrical current connection extending from an interior volume of the gas container beyond an outer surface of the gas container for conducting electrical current into the gas container, the adapter mechanism comprising: a housing for at least partially surrounding the current connection in the circumferential direction of the current connection, the housing having a cover with a through-hole for contactless withdrawal of the current connection from the housing; - container sealing means for sealingly attaching the housing to a gas container; - bearing means for mounting the current connection inside the housing; - first insulating means for positioning at least partially inside the housing between the bearing means and the cover for electrical insulation between the bearing means and the cover; housing sealing means for attachment to the current connection brought out of the housing in order to seal the gap between the current connection and the cover; - second insulating means for positioning at least partially between the housing sealing means and the cover on the exterior of the housing for electrical insulation between the housing sealing means and the cover.

[0006] The adapter mechanism according to the invention allows for a simple and reliable gas-tight conduction of electric current into the gas container, i.e., it is possible to prevent gas from escaping from the gas container via the adapter mechanism into the surroundings while electric current is being passed through the gas container. The gas container can be understood as a catalyst housing of an electrically heatable catalyst, in particular a metal catalyst, such as Emicats.

[0007] The adapter mechanism according to the invention can be realized by simple means. In addition to standard components, objects with simple geometries can be used to realize the adapter mechanism, for example, a simple hollow cylinder for the housing. This allows the adapter mechanism to be manufactured quickly and inexpensively. Furthermore, the adapter mechanism can be realized in a relatively small design space.

[0008] The housing may have a housing mantle section that extends mantle-like at least partially around the current connection. The housing mantle section is preferably configured cylindrically and / or tubular. "The housing at least partially surrounds the current connection" can be understood to mean that the housing and / or the housing mantle section only extend around a portion of the current connection in the longitudinal direction of the current connection. "The housing is configured to at least partially surround the current connection in the circumferential direction of the current connection" can be understood to mean that the housing mantle-like surrounds the current connection in the longitudinal direction of the current connection.

[0009] The cover, when removed from the housing jacket section, is preferably disk- and / or plate-shaped, preferably with a through-hole formed in its center. It is particularly preferred that the housing jacket section and the cover be provided as components that are materially joined to one another at at least one location, thereby simplifying the attachment of the adapter mechanism to the gas bottle.

[0010] Contactless leading out of the current connection from the housing is understood to mean leading out of the current connection from the housing without any direct mechanical contact between the current connection and the housing, whereby short circuits and / or other electrical malfunctions can be prevented, since the current connection and the housing preferably consist of metal and / or an electrically conductive material.

[0011] The diameter and / or dimensions of the through-hole are selected to be correspondingly larger than the diameter and / or dimensions of the existing current contacts and / or desired current connections in the region of the through-hole.

[0012] The container sealing means can be understood as a means for connecting the gas container and the housing in a materially joined manner. The container sealing means preferably has a welded seam, by which the housing can be attached to the gas container, in particular at least to the outer surface of the gas container. The container sealing means is preferably provided to make the area where the housing is attached to the gas container gas-tight. That is, the container sealing means does not need to seal the entire container against gas leakage.

[0013] The bearing means serves to fix the first insulating means in a desired position. The bearing means can therefore be understood as a corresponding bearing for the cover, more precisely for the inner surface of the cover facing the interior volume of the housing. The bearing means can be positioned directly on the first insulating means, preferably with direct surface contact between the bearing means and the first insulating means, in order to position the first insulating means.

[0014] Sealing a gap can be understood as hermetically closing at least one gap between the current connection and the cover, which occurs when the current connection is pulled out of the housing through the through-hole without contact. That is, the housing sealing means is preferably configured to prevent gas leakage from the housing. The prevention of gas leakage can be achieved directly or indirectly. For example, the housing sealing means can hermetically close the gap directly or by means of an auxiliary means, such as a second insulating means.

[0015] The first insulating means and the second insulating means may each comprise a disk-shaped insulating ring or may be configured as a disk-shaped insulating ring for annular arrangement around the current connection. The first insulating means and / or the second insulating means may each be configured to seal the container against gas leakage from the housing.

[0016] The first insulating means and / or the second insulating means may be made of or have a correspondingly elastic plastic. Preferably, the first sealing means and / or the second sealing means are each constructed integrally. However, in one preferred embodiment, the insulating means may be made of a non-conductive, shape-stable material, for example ceramic, or may at least correspondingly have such a material for the electrical insulating function.

[0017] In yet another embodiment of the present invention, the current connection in the adapter mechanism can have a first current connection thread section, and the bearing means can have at least one nut for screwing onto the first thread section. This allows the bearing means to be provided particularly simply and cost-effectively. The bearing means preferably has two nuts, one of which serves as a counter-nut. Threaded engagement can be understood as a screw-in, a threaded engagement, or a threaded engagement. Accordingly, the thread section can have an external or internal thread. Preferably, the first current connection thread section is configured as an internal thread on the inner circumferential surface of the bearing means and / or the at least one nut, or has an internal thread that can be screwed onto the corresponding external thread of the current connection.

[0018] Furthermore, in the adapter mechanism according to the present invention, the current connection can have a second current connection thread section, and the housing seal means can have at least one nut for threading onto the second thread section. That is, the nut can be threaded onto the second thread section. This also allows the adapter mechanism to be constructed relatively simply and at low cost. For example, the at least one nut of the housing seal means can be threaded onto the second insulating means until an airtight closure for sealing the housing is achieved. The housing seal means can have another nut that can be threaded onto the second current connection thread section as a counter nut to secure the first nut of the housing seal means.

[0019] It may further be preferred if the adapter mechanism according to the invention comprises clamping means arranged or positionable at least partially between the bearing means and the first insulating means for urging the first insulating means towards the cover.

[0020] This allows for easy positioning of the first insulating means at the desired position on the cover, specifically on the inner surface of the cover. The clamping means can have an integral spring element. The clamping means is preferably configured annularly for fitting onto the current connection. Furthermore, the adapter mechanism according to the invention can have at least one annular positioning washer between the bearing means and the first insulating means, between the housing seal means and the second insulating means, and / or between the bearing means and the clamping means, and / or between the clamping means and the first insulating means. This allows for easy, reliable, and efficient transmission of forces to the respective components in a cost-effective and reliable manner. In this context, annular is preferably understood to mean a shape formed by two concentrically arranged outer jacket sections that are circular in cross section. Nevertheless, the outer and / or inner circumferential surfaces of the annular element according to the invention may also be configured elliptical and / or rectangular, e.g., hexagonal, like a nut. Preferably, the insulating means are each configured in the shape of a disk, i.e. with a flat or substantially flat upper surface and a flat lower surface.

[0021] In yet another variant of the invention, the adapter mechanism can have an elastically deformable first current-conducting means having a current-conducting means mounting section for mounting the first current-conducting means to the current connection on the outside of the housing, for picking up current from the current connection via the first current-conducting means. The first current-conducting means allows for a simple and cost-effective compensation of thermally induced size differences between the gas bottle, the current connection and / or the housing. Preferably, the current-conducting means mounting section has a current-conducting means thread section, in particular an internal thread, in and / or on the current-conducting means for screwing the current-conducting means to the current connection.

[0022] The first current conducting means is preferably configured as a plate or substantially as a plate, i.e. the length and width of the current conducting means are each several times longer and / or larger than the height of the current conducting means, and the current conducting means preferably has a flat or substantially flat upper surface and a flat or substantially flat lower surface.

[0023] The current conducting means may be configured as a rectangular parallelepiped or substantially rectangular parallelepiped, in particular with regard to the outer contour of the current conducting means.

[0024] Additionally, the inventive adapter arrangement according to the present invention may have fastening means for non-destructively and removably fastening the first current-conducting means to the current connection at least partially between the fastening means and the housing sealing means. The fastening means allow particularly easy assembly and disassembly in the case of maintenance and / or repair. In the adapter arrangement according to the present invention, it may be preferred if the current connection has a second current connection thread section and if the fastening means has at least one nut for screwing onto the second current connection thread section.

[0025] In yet another aspect of the present invention, an adapter mechanism for conducting electrical current into a gas container in an airtight manner is provided, the gas container including a prong-like electrical current connection extending from an interior volume of the gas container beyond an exterior surface of the gas container for conducting electrical current into the gas container, the adapter mechanism comprising: a housing for at least partially surrounding the current connection in the circumferential direction of the current connection, the housing having a cover with a through hole; a coupling component with a coupling component mounting area for mounting the coupling component on a current connection for electrical contact between the current connection and the coupling component and for conducting current through the coupling component into the gas container through the current connection, the coupling component being configured with a through-hole for contactless withdrawal of the coupling component mounted on the current connection from the housing; - container sealing means for sealingly attaching the housing to a gas container; - bearing means for mounting the coupling component inside the housing; - first insulating means positioned at least partially inside the housing between the bearing means and the cover for electrical insulation between the bearing means and the cover; housing sealing means for mounting in the withdrawn area of ​​the coupling component to seal the gap between the coupling component and the cover; - second insulating means positioned at least partially between the housing sealing means and the cover on the exterior of the housing for electrical insulation between the housing sealing means and the cover.

[0026] The adapter arrangement according to this aspect essentially corresponds to the embodiment according to the first aspect, but the housing is sealed around the coupling component rather than around the current connection. This has the advantage that the adapter arrangement can be used and / or assembled more easily and / or flexibly with different gas containers and / or current connections. The requirements explained above for the adapter arrangement at the current connection in the region of the housing, in particular in the region of the through-hole, also apply correspondingly to the adapter arrangement according to the second aspect with respect to the coupling component.

[0027] For example, in the adapter mechanism according to the second aspect, the coupling component may have a first coupling component thread section, the bearing means may have at least one nut for threading onto the first thread section, and the coupling component may have a second coupling component thread section, and the housing seal means may have at least one nut for threading onto the second thread section.

[0028] Similarly, the adapter mechanism including the coupling component may have clamping means disposed at least partially between the bearing means and the first insulating means for pressure biasing the first insulating means towards the cover.

[0029] The resiliently deformable first current conducting means may have a current conducting means attachment area for attaching the coupling component to the first current conducting means outside the housing for picking up current from the coupling component via the first current conducting means. The fixing means may be configured for non-destructively removably fixing the first current conducting means to the coupling component at least partially between the fixing means and the housing sealing means.

[0030] Additionally, in the adapter mechanism according to the second aspect, the coupling component may have a second coupling component thread section, and the fastening means may have at least one nut for threading onto the second coupling component thread section. The coupling component mounting section may have a third coupling component thread section for threading the coupling component onto a corresponding current connection thread section of the current connection. This allows the coupling component to be quickly, easily, and reliably coupled to the current connection. Preferably, the third coupling component thread section has an internal thread that can be threaded onto the corresponding external thread of the current connection.

[0031] In a further variant of the invention, the coupling components of the adapter arrangement according to the second aspect can be configured integrally, in particular in the form of pins and / or studs, thereby providing an adapter arrangement that is particularly stable, space-saving and cost-effective.

[0032] It may further be preferred if the coupling component in the adapter arrangement of the invention has a fourth coupling component thread section on the end face of the coupling component for a threaded connection between a further current connection and the coupling component.

[0033] Accordingly, a current connection area for connecting a further current connection to the coupling component outside the housing can be embodied in a space-saving and simple manner.

[0034] The adapter mechanism according to the present invention can further include an elastically deformable second current-conducting means, which mechanically couples the current connection and the coupling component to one another for electrical connection between the current connection and the coupling component via the second current-conducting means. The second current-conducting means allows for thermally induced size differences between the gas container, the current connection, the coupling component, and / or the housing to be compensated for in a simple and cost-effective manner. The second current-conducting means preferably includes a first current-conducting means-threaded section and / or a second current-conducting means-threaded section, each having an internal thread and / or a surface thereof. The threaded sections allow for easy coupling of the second current-conducting means with the current connection and / or the coupling component to establish the desired electrical connection between the current connection, the second current-conducting means, and the coupling component.

[0035] The second current conducting means is preferably configured in a plate-like or substantially plate-like shape. Furthermore, the second current conducting means preferably has a flat or substantially flat upper surface and a flat or substantially flat lower surface. The current conducting means may be configured in a rectangular or substantially rectangular shape, in particular with regard to the outer contour of the current conducting means.

[0036] In yet another aspect of the present invention, a component composite is provided, the component composite comprising a gas container having an outer surface and a protrusion-like current connection extending from an interior volume of the gas container beyond the outer surface of the gas container for conducting electrical current into the gas container, and the component composite further comprising an adapter mechanism, as described in detail above, attached to the outer surface and the current connection.

[0037] The component composite according to the invention thereby offers the same advantages as those explained in detail with respect to the adapter arrangement according to the invention.The current connections are preferably configured in the form of pins and / or studs.

[0038] Further ways of improving the invention will become apparent from the following description of various embodiments of the invention which are illustrated diagrammatically in the drawings. [Brief explanation of the drawings]

Furthermore, the adapter mechanism 10a has a container sealing means 18 in the form of a weld seam for gastightly attaching the housing 14 to the gas container 11. That is, the housing 14 is joined to the gas container 11 in a material-bonded manner by the weld seam of the container sealing means 18. The adapter mechanism 10a further includes a bearing means 19 attached to the current connection 12 inside the housing 14.

Accordingly, the through-hole 16 is configured for contactlessly withdrawing the coupling component 17 attached to the current connection 12 from the housing 14.
