Description

[0001] Feedthrough device

[0002] The invention relates to a feedthrough device for plug-in elements.

[0003] In various applications, it is helpful or necessary to provide a penetration for electrical cables in or through a wall. One example of such an application is walls in means of transport, particularly in trains or ships. For instance, bulkheads are used to isolate and / or seal a train car or parts of a ship from the outside. Penetrations in bulkheads must be as airtight as possible.

[0004] In general, for example in carriage transition systems, such as in trains, it is necessary or advantageous that when electrical cables are routed along a wall, for example a bulkhead wall, the cables are tightly sealed in a plug on both sides and connected together at the wall.

[0005] Approaches for wall penetrations exist in other technical fields.

[0006] DE 10 2012 005 043 Al relates to an electrical wall feedthrough for solar power systems. It describes a single-sided pluggable wall feedthrough for connecting a live conductor of a solar generator to a connection housing, comprising: a two-part connector housing with a front housing part and an insert part, which, together with an electrical connection element, is displaceable as a unit relative to the front housing part, wherein the connection element is pluggable on one side and has a spring-loaded clamp on the other side, and wherein, in the closed state, the spring-loaded clamp is surrounded by a sleeve of the front housing part, and in the open state, the clamping device is pulled out of the sleeve to allow it to be opened and closed, and wherein the insert part has an exposed grip section for the user.

[0007] German patent DE 10 2011 112 283 A1 relates to a modular electrical connector system for solar power systems. The patent discloses a connector system for solar power systems that includes a wall feedthrough that can be plugged in from both sides. This system utilizes a number of components, in particular housing parts and single-sided pluggable metal contact elements from single-sided pluggable wall feedthroughs. Only two mating parts with connector housings need to be newly created, and the existing single-sided pluggable metal contact elements are directly connected to their crimp terminals from the rear. This can be done by welding, soldering, or direct crimping.

[0008] The existing feedthroughs have a complex design and / or require custom components, especially custom connectors. Therefore, there is a need for a simpler feedthrough device. In particular, there is a need for a feedthrough device that can also be used with standard components, such as standard connectors.

[0009] According to a first aspect, a feed-through device for plug-in elements is provided. The feed-through device has a first plug-in element. For example, the first plug-in element is designed as a first housing through which one or more electrical conductors can be passed or guided, and / or in which one or more electrical conductors can be or are sectionally received.

[0010] The feedthrough device includes a feedthrough arrangement. The feedthrough arrangement is designed such that it can be arranged on a wall, in particular on a partition wall, and provides a feedthrough through the wall.

[0011] The feedthrough device comprises a first spacer assembly. The first spacer assembly is connected to the first plug-in element and is designed to project from the first plug-in element. The feedthrough device also comprises a first adapter element. The first adapter element is arranged and designed on the first spacer assembly such that it can be inserted into the feedthrough device.

[0012] The feedthrough device has a simple design. By attaching the first adapter element to the first spacer assembly projecting from the first plug-in element, the first adapter element also projects from the first plug-in element. Furthermore, the first adapter element is designed, for example, dimensioned so that it can be inserted into the feedthrough assembly. For example, the outer circumference of the first adapter element is smaller than the inner circumference of the feedthrough assembly, in particular the feedthrough provided by the feedthrough assembly in or through the wall. In this way, the first adapter element can be inserted into the feedthrough assembly, in particular into the feedthrough provided by the feedthrough assembly. The first plug-in element can be located on a first side of the wall in its initial state.

[0013] The penetration assembly can comprise a frame and / or penetration device. Preferably, the frame and / or penetration device can be designed in two parts, with a first part being attachable to a first side of the wall and a second part being attached to a second side of the wall. Each part can project at least partially into the penetration in the wall. In particular, each part has a sealing device for sealing against the wall. Specifically, each part includes at least one mounting interface, e.g., at least one screw hole, by means of which each part can be attached, in particular screwed, to the respective side of the wall. Alternatively, the frame or penetration device can be designed as a single piece and attached to one side of the wall.In this embodiment, the frame and / or feedthrough assembly is preferably arranged and attached to only one side of the wall, preferably projecting at least partially through the wall. An advantage is that the one-piece frame or feedthrough assembly requires only one sealing element and that the number of mounting interfaces can be reduced compared to the two-piece version. This reduces costs and installation effort. A further advantage of the one-piece design is that the length of the spacer assembly is independent or largely independent of the wall thickness.

[0014] The first plug-in element can be mounted as a housing onto the frame and / or feedthrough assembly, in the case of a two-part design, particularly onto one of the two parts. In the case of a one-piece design of the frame and / or feedthrough assembly, the first plug-in element can be coupled to it on one side of the wall or within the feedthrough. Preferably, the first plug-in element has a sealing device by means of which a gas- and / or liquid-tight connection can be formed with respect to the frame and / or feedthrough assembly. The first spacer assembly can be designed such that the first adapter element connected to the first spacer assembly can pass through the feedthrough assembly.For example, the length of the first spacer arrangement and / or the attachment of the first adapter element to the first spacer arrangement can be designed such that the first adapter element can pass through the feedthrough arrangement, in particular through the feedthrough provided by means of the feedthrough arrangement.

[0015] The first adapter element connected to the first spacer assembly can be passed through the feedthrough assembly in such a way that the first adapter element protrudes at least partially from the feedthrough assembly. In other words, at least a part or section of the first adapter element protruding from the feedthrough assembly can be made contact from another (second) side of the wall. In particular, in an initial state, the first plug-in element and the first adapter element can be arranged on a first side of the wall. If the first plug-in element is brought into a final state in which it rests against or comes into contact with the feedthrough assembly, the first adapter element projects into the feedthrough assembly in such a way that a part or section of the first adapter element protrudes from the feedthrough assembly on a second side of the wall.The protruding part or section of the first adapter element may in particular be an end section or front section of the first adapter element.

[0016] The first adapter element can have at least one connector insert. The first adapter element can be connected via the connector insert, for example, to a plug-in element or another adapter element. Additionally or alternatively, one or more electrical conductors can be routed from the first plug-in element to the first adapter element by means of the first spacer arrangement, or can run substantially along the first spacer arrangement and / or between two spacers of the first spacer arrangement. In particular, the first spacer arrangement can be configured as a holder for one or more electrical conductors and / or for guiding the electrical conductor(s) from the first plug-in element to the first adapter element, especially the at least one connector insert.This allows an electrical connection to be provided between the first adapter element, in particular the at least one plug insert, and the first plug element. Additionally or alternatively, the first spacer arrangement can have at least one first spacer, in particular cylindrical, cuboid, or planar. Alternatively, the at least one first spacer can be tubular to allow the passage of the electrical conductor(s). In particular, one or more electrical conductors can extend along the at least one first spacer to form an electrical connection between the first adapter element, in particular the at least one plug insert, and the first plug element. The at least one first spacer can, in particular, bent from sheet metal, milled from a block, or milled, printed, or injection-molded from plastic.For example, the first spacer assembly can have exactly two spacers projecting from the first plug-in element in the same direction. This same direction can correspond to the insertion direction of the first adapter element into the feedthrough assembly.

[0017] The feedthrough device may further comprise a second plug-in element. For example, the second plug-in element is designed as a second housing through which one or more additional electrical conductors can be routed or are routed, and / or in which one or more additional electrical conductors can be or are sectionally accommodated. In its initial state, the second plug-in element may be located on a second side of the wall. The second plug-in element can be mounted as the second housing onto the frame and / or feedthrough device, in the case of a two-part design, particularly onto the other of the two parts. In the case of a one-piece design of the frame and / or feedthrough device, the second plug-in element can be coupled to the wall on the other side or within the feedthrough through the wall.Preferably, the second plug-in element has a sealing device by means of which a gas- and / or liquid-tight connection can be formed with respect to the frame and / or feedthrough device.

[0018] According to a first embodiment, the first adapter element connected to the first spacer assembly can be inserted into the feedthrough assembly in such a way that contact between the first adapter element and the second plug-in element is enabled. In particular, the first adapter element connected to the first spacer assembly can be passed through the feedthrough assembly in such a way that contact between the first adapter element and the second plug-in element is enabled. For this purpose, for example, in an end state of the first plug-in element (in which the first plug-in element rests against the feedthrough assembly), the first adapter element can be guided through the feedthrough assembly from the first side of the wall. A part or section of the first adapter element protruding from the feedthrough assembly can be made contactable on the second side of the wall, for example by means of the second plug-in element.This allows a connection to be established between the first adapter element and the second plug-in element, and, if the first adapter element is electrically connected to the first plug-in element, a connection between the first plug-in element and the second plug-in element can be established. Preferably, the second plug-in element comprises at least one mating plug-in insert to establish the electrical connection with the plug-in insert of the first adapter element. In particular, the mating plug-in insert is at least partially integrated into the second plug-in element. In this embodiment, the mating plug-in insert is electrically connected to the other electrical conductor(s) within the second housing. This allows electrical contact to be established with the plug-in insert of the first adapter element when the first adapter element passes through the feedthrough arrangement, in particular through the feedthrough in the wall.

[0019] The feedthrough device may further comprise a second spacer arrangement. The second spacer arrangement may be connected to the second plug-in element and configured to project from it. The feedthrough device may comprise at least one second adapter element. The second adapter element may be arranged and configured on the second spacer arrangement such that it can be inserted into the feedthrough device. The first spacer arrangement and the second spacer arrangement may, for example, be identical or the same. The second adapter element and the first adapter element may have the same or identical external shape or contour. The first adapter element and the second adapter element may differ in their plug-in inserts.For example, the first adapter element can have a plug insert and the second adapter element can have a corresponding or complementary mating plug insert.

[0020] According to a second embodiment, the second adapter element connected to the second spacer assembly can be inserted into the feedthrough assembly in such a way that contact between the first adapter element and the second adapter element is enabled. For example, the second spacer assembly can be designed and the second adapter element can be arranged on the second spacer assembly in such a way that the second adapter element can be inserted into the feedthrough assembly, but, in a final state of the second plug-in element (in which the second plug-in element is, for example, in contact with the feedthrough assembly), does not protrude on the other (first) side.Accordingly, the first spacer assembly can be designed and the first adapter element can be arranged on the first spacer assembly such that the first adapter element can be inserted into the feedthrough assembly, but, in a final state of the first plug-in element (in which the first plug-in element rests against the feedthrough assembly, for example), does not protrude from the other (second) side of the wall. In this case, the first adapter element and the second adapter element can meet or collide in the area of ​​the feedthrough assembly, particularly in the area of ​​the feedthrough provided by the feedthrough assembly, and establish contact or a connection with each other.This allows a connection to be established between the first adapter element and the second adapter element, and, if the first adapter element is electrically connected to the first plug-in element and if the second adapter element is electrically connected to the second plug-in element, a connection can be established between the first plug-in element and the second plug-in element.

[0021] The second adapter element may have a mating connector insert that corresponds to or is complementary to the first adapter element or plug-in element. The second adapter element may be contactable via this mating connector insert, for example, by connecting it to another plug-in element or adapter element, in particular a plug-in insert of the first plug-in element or adapter element. Additionally or alternatively, the second spacer assembly may allow the further electrical conductor(s) to be routed to or guided to the second adapter element, or may run essentially along the first spacer assembly and / or between two second spacers of the second spacer assembly.In particular, the second spacer arrangement can be designed as a holder for one or more electrical conductors and / or for guiding the electrical conductor(s) from the second plug-in element to the second adapter element, especially the at least one mating plug-in insert. This allows an electrical connection to be provided between the second adapter element and the second plug-in element. Additionally or alternatively, the second spacer arrangement can have at least one second spacer, in particular cylindrical, cuboid, or flat. Alternatively, the at least one second spacer can be tubular to allow the passage of the electrical conductor(s).In particular, one or more electrical conductors can extend along the at least one second spacer to form an electrical connection between the second adapter element, especially the at least one mating connector insert, and the second plug-in element. The at least one second spacer can be bent from sheet metal, milled from a block, or milled, printed, or injection-molded from plastic. For example, the second spacer arrangement can have exactly two spacers projecting from the second plug-in element in the same direction. This same direction can correspond to the insertion direction of the second adapter element into the feedthrough arrangement.

[0022] According to a second aspect, a wall, in particular a bulkhead, with a penetration device according to the first aspect is proposed. According to a third aspect, a means of transport, in particular a train or a ship, with a penetration device according to the first aspect or a wall, in particular a bulkhead, according to the second aspect is proposed. Even if some details have been / are described only with regard to the penetration device according to the first aspect, these details can be / will be implemented accordingly in the wall according to the second aspect and / or in the means of transport according to the third aspect.

[0023] The invention is explained below by way of example with reference to the accompanying figures. These represent:

[0024] Figs. a1-a1d schematic representations of a feedthrough device according to a first embodiment;

[0025] Figs. 2a-2d schematic representations of a feedthrough device according to a second embodiment; and

[0026] Figs. 3a-3d schematic representations of a feedthrough device according to a third embodiment.

[0027] Figures 1a to 1ld show a feedthrough device 10 according to a first embodiment in various representations and views. Figure 1a shows a side view of the feedthrough device according to the first embodiment in a connected state, in which the individual components are shown separately (not connected). Figure 1b shows a sectional view of the representation from Figure 1a. Figure 1c shows a perspective view of the feedthrough device 10 according to the first embodiment. Figure 1d shows a side view of the feedthrough device 10 according to the first embodiment, in which the components are connected. The first embodiment is essentially described collectively with reference to Figures 1a to 1d.

[0028] Figures 1a to 11d show a feedthrough arrangement 300 and a first plug-in element 100 of a feedthrough device 10 according to the first embodiment. The feedthrough arrangement 300 has a frame and / or feedthrough assembly 320a, 320b, which in the first embodiment is formed in two parts, a first part 320a and a second part 320b. The feedthrough arrangement 300, and in particular the two-part frame and / or feedthrough assembly 320a, 320b, can have sealing devices (not visible) and mounting interfaces, which for the sake of simplicity are not (all) shown in Figure 1a. In particular, each part 320a, 320b has a sealing device for sealing against the wall 1. Specifically, each part 320a, 320b includes at least one mounting interface, e.g.at least one screw hole by means of which each part 320a, 320b can be attached, in particular screwed, to the respective side aa, bb of the wall 1.

[0029] The feedthrough device 10 comprises, in addition to the first plug-in element 100 and the feedthrough assembly 300, a first spacer assembly 400 and a first adapter element 500. The feedthrough assembly 300 is designed such that it can be arranged on a wall 1 and provides a feedthrough through the wall 1. The wall 1 is designed as a bulkhead wall and is therefore sometimes also referred to as bulkhead wall 1. The first plug-in element 100 is located on a first side 1a of the wall 1 in Figure 1a. The first spacer assembly 400 is connected to the first plug-in element 100 and is designed to project from the first plug-in element 100. The first spacer assembly 400 has, as can be seen with reference to Figure 1c, exactly four cylindrical or tubular spacers. In Figures 1a to 1c, the spacers project towards the wall 1 and the feedthrough assembly 300.As can be further seen in Figures 1a to 1c, the first adapter element 500 also has at least one plug insert 120, or at least one plug insert 120 is formed on the first adapter element 500. The first adapter element 500 is arranged and configured on the first spacer assembly 400 such that it can be inserted into the feedthrough assembly 300. More precisely, the first adapter element 500 can be inserted into the feedthrough formed by the feedthrough assembly 300. In Figures 1a to 1c, the first plug element 500 is in an initial state on the first side 1a of the wall. In this initial state, the first adapter element 500 is not inserted into the feedthrough assembly 300 and the first plug element 500 is not in contact with the feedthrough assembly 300.

[0030] In Figures 1a to 1c, a second plug-in element 200 is further arranged on a second side 1b of the wall 1. In contrast to the first plug-in element 100, the second plug-in element 200 in the feedthrough device 10 according to the first embodiment has no spacer arrangement and no adapter element. As can also be seen in Figure 1b, the second plug-in element 200 has a mating plug insert 220, or a mating plug insert 220 is formed on the second plug-in element 200. Preferably, the first plug-in element 100 and the second plug-in element 200 each have a sealing device by means of which a gas- and / or liquid-tight connection can be formed with respect to the frame and / or feedthrough device 320a, 320b.

[0031] In Figure 11, the first plug-in element 100 and the second plug-in element 200 are in a final state in which the first plug-in element 100 is in contact with the feedthrough arrangement 300. More precisely, in this final state, an end section of the first plug-in element 100 rests against an outer section of the feedthrough arrangement 300. According to the first embodiment of the feedthrough device 10, the first spacer arrangement 400 is configured such that, in this final state, the first adapter element 500 connected to the first spacer arrangement 400 passes through the feedthrough arrangement 300. Consequently, the first adapter element 500 protrudes at least partially from the feedthrough arrangement 300. More precisely, at least a front section of the first adapter element 500 protrudes from the feedthrough arrangement 300 on the second side 1b of the wall 1.

[0032] As described, a plug insert 120 is formed on the first adapter element 500 as an example. More precisely, a plug insert 120 is formed on the front section of the first adapter element 500 that protrudes from the feedthrough arrangement 300 as an example.

[0033] As described, the feedthrough device 10 according to the first embodiment further comprises a second plug-in element 200. Figures 1a to 1c show an initial state of the second plug-in element 200. As previously described, the first adapter element 500, connected to the first spacer arrangement 400, can pass through the feedthrough arrangement 300, and a front section of the first adapter element 500 can protrude from the feedthrough arrangement 300. This enables contact between the first adapter element 500 and the second plug-in element 200. For this purpose, a mating plug insert 220, corresponding to or complementary to the plug insert 120 of the first adapter element 500, is provided or arranged on the second plug-in element 200.When the second plug-in element 200 is brought into a final state in which the second plug-in element, more precisely a front section of the second plug-in element 200, rests against an outer section of the feedthrough arrangement 300 on the second side lb of the wall 1, a connection is established between the second plug-in element 200, more precisely a mating plug-in insert 220 provided in a front section of the second plug-in element 200, and the first adapter element 500, more precisely a plug-in insert 120 provided on the front section of the first adapter element 500, when the first plug-in element 100 is also in its final state (see figure ld).

[0034] Furthermore, by way of example, one or more electrical conductors (not shown) are routed to the first adapter element 500 through the first spacer arrangement 400. When the second plug-in element 200 is connected to the first adapter element 500, a tight connection is thereby established between the second plug-in element 200 and the first plug-in element 100 through the wall 1.

[0035] Figures 2a to 2d show a feedthrough device 10 according to a second embodiment in various representations and views. Figure 2a shows a side view of the feedthrough device according to the second embodiment in a connected state, in which the individual components are shown separately (not connected). Figure 2b shows a sectional view of the representation from Figure 2a. Figure 2c shows a perspective view of the feedthrough device 10 according to the second embodiment. Figure 2d shows a side view of the feedthrough device 10 according to the second embodiment, in which the components are connected. The second embodiment is essentially described collectively with reference to Figures 2a to 2d.The second embodiment differs essentially from the first embodiment in the design of the first 100 and second plug-in element 200, as described below. Figures 2a to 2d show a feedthrough arrangement 300 and a first plug-in element 100 of a feedthrough device 10 according to a second embodiment. The feedthrough arrangement 300 has a frame and / or feedthrough assembly 320a, 320b, which in the second embodiment (as in the first embodiment) is formed in two parts, a first part 320a and a second part 320b. The feedthrough arrangement 300, and in particular the two-part frame and / or feedthrough assembly 320a, 320b, can have sealing devices (not visible) and assembly interfaces, as sketched with reference to the first embodiment.

[0036] The feedthrough device 10 comprises, in addition to the first plug-in element 100 and the feedthrough assembly 300, a first spacer assembly 400 and a first adapter element 500. The feedthrough assembly 300 is designed such that it can be arranged on a wall 1 and provides a feedthrough through the wall 1. The wall 1 is, for example, designed as a bulkhead and is therefore sometimes also referred to as bulkhead 1. The first spacer assembly 400 is connected to the first plug-in element 100 and is designed to project from the first plug-in element 100. The first spacer assembly 400 has, for example, as can be seen in Figure 2c, exactly four cylindrical or tubular spacers. In Figures 2a to 2c, the spacers project in the direction of the wall 1 and the feedthrough assembly 300.

[0037] The first spacer arrangement 400 according to the second embodiment shown in Figures 2a to 2d differs from the first spacer arrangement 400 according to the first embodiment shown in Figures 1a to 1ld in that the first spacer arrangement 400 from Figures 2a to 2d is shorter than the first spacer arrangement from Figures 1a to 1ld. More precisely, the first spacer arrangement 400 from Figures 2a to 2d is at least approximately half as long as the first spacer arrangement 400 from Figures 1a to 1ld. Even more precisely, the two spacers of the first spacer arrangement 400 from Figures 2a to 2d are at least approximately half as long as the two spacers of the first spacer arrangement 400 from Figures 1a to 1ld.As can be further seen in Figures 2a to 2c, the first adapter element 500, according to the first embodiment shown in Figures 1a to 11d, also has at least one plug insert 120 on or is formed on the first adapter element 500. The first adapter element 500 is arranged and configured on the first spacer assembly 400 such that it can be inserted into the feedthrough assembly 300. More precisely, the first adapter element 500 can be inserted into the feedthrough 320 formed by the feedthrough assembly 300. In Figures 2a to 2c, the first plug element 500 is in an initial state on the first side 1a of the wall 1. In this initial state, the first adapter element 500 is not inserted into the feedthrough assembly 300 and the first plug element 500 is not in contact with the feedthrough assembly 300.

[0038] In Figures 2a to 2c, a second plug-in element 200 is further arranged on a second side lb of the wall 1. In contrast to the second plug-in element 200 according to the first embodiment shown in Figures 1a to 11d, the second plug-in element 200 according to the second embodiment has a spacer assembly 600 and an adapter element 700. The spacer assembly 600 arranged on the second plug-in element 200 is designed, by way of example, like the spacer assembly 400 designed on the first plug-in element 100. Furthermore, the adapter element 700 arranged on the second plug-in element 200 is arranged, by way of example, according to the adapter element 500. As can also be seen in Figures 2a and 2b, the second adapter element 700 has a mating plug insert 220, or a mating plug insert 220 is formed on the second adapter element 700.

[0039] In Figure 2d, the first plug-in element 100 and the second plug-in element 200 are in a final state in which the first plug-in element 100 is in contact with the feedthrough arrangement 300. More precisely, in this final state, an end section of the first plug-in element 100 rests against an outer section of the feedthrough arrangement 300. According to the second embodiment of the feedthrough device 10, the first spacer arrangement 400 is designed such that, in this final state, the first adapter element 500 connected to the first spacer arrangement 400 is inserted through the feedthrough arrangement 300, but cannot pass through it in such a way that the first adapter element 500 protrudes at least partially from the feedthrough arrangement 300.More precisely, the first adapter element 500, in the final state of the first plug-in element 100, does not protrude from the feedthrough arrangement 300, but remains within the area of ​​the feedthrough arrangement 300, more precisely within the area of ​​the feedthrough 320.

[0040] As described, a plug insert 120 is formed on the first adapter element 500. More precisely, a plug insert 120 is formed on the front section of the first adapter element 500. As described, the feedthrough device 10 according to the second embodiment also has a second plug element 200. In Figures 2a to 2c, the second plug element 200 is in an initial state. The feedthrough device 10 according to the second embodiment also has, as described, a second spacer arrangement 600. The second spacer arrangement 600 is connected to the second plug element 200 and is designed to project from the second plug element 200. The feedthrough device 10 according to the second embodiment also has, as described, a second adapter element 700.The second adapter element 700 is arranged and designed on the second spacer assembly 600 such that it can be inserted into the feedthrough assembly 300. The contour of the second spacer assembly 600 and the second adapter element 700 of the feedthrough device 10 according to the second embodiment corresponds at least nearly to that of the first spacer assembly 400 and the first adapter element 500 of the feedthrough device 10 according to the second embodiment.

[0041] The second adapter element 700, connected to the second spacer arrangement 600, can be inserted into the feedthrough arrangement 300 in such a way that contact between the first adapter element 500 and the second adapter element 700 is enabled. For this purpose, a mating connector insert 220 can be provided or arranged on a front section of the second adapter element 700, which corresponds to or is complementary to the connector insert 120 of the first adapter element 500.If the second plug-in element 200 is brought into a final state in which the second plug-in element 200, more precisely a front section of the second plug-in element 200, rests against an outer section of the feedthrough arrangement 300 on the second side lb of the wall 1, a connection is established between the second adapter element 700, more precisely a mating plug-in insert provided in a front section of the second adapter element 700, and the first adapter element 500, more precisely a plug-in insert provided on the front section of the first adapter element 500, when the first plug-in element 100 is in its corresponding final state (see Figure 2d).

[0042] Furthermore, by way of example, one or more electrical conductors (not shown) are guided to the second adapter element 700 by the second spacer arrangement 600. When the second adapter element 700 is connected to the first adapter element 500, a tight connection is thereby established between the second plug-in element 200 and the first plug-in element 100 through the wall 1. Figures 3a to 3d show a feedthrough device 10 according to a third embodiment in various representations and views. Figure 3a shows a side view of the feedthrough device 10 according to the third embodiment in a plugged-in state, in which the individual components are shown separately (not plugged in). Figure 3b shows a sectional view of the representation from Figure 3a. Figure 3c shows a perspective view of the feedthrough device 10 according to the third embodiment.Figure 3d shows a side view of the feedthrough device 10 according to the third embodiment, in which the components are plugged together. The third embodiment is essentially described jointly with reference to Figures 3a to 3d. The third embodiment differs from the first embodiment essentially in the design of the frame and / or feedthrough device 320.

[0043] Figures 3a to 3d show a feedthrough arrangement 300 and a first plug-in element 100 of a feedthrough device 10 according to the third embodiment. The feedthrough arrangement 300 has a frame and / or feedthrough assembly 320, which in the third embodiment is formed in one piece. The one-piece frame and / or feedthrough assembly 320 is shown by way of example in Figures 3a to 3c on side 1a of the wall 1, on which the first plug-in element 100 is located, but can also be arranged on the other side 1b of the wall 1. The feedthrough arrangement 300 and, in particular, the one-piece frame and / or feedthrough assembly 320 can have sealing devices (not visible) and assembly interfaces, which for the sake of simplicity are not (all) shown in Figure 3a.In particular, the one-piece frame and / or feedthrough device 320 has a (single) sealing device for sealing against the wall 1. Specifically, the one-piece frame and / or feedthrough device 320 includes at least one mounting interface, e.g., at least one screw hole, by means of which the one-piece frame and / or feedthrough device 320 can be attached, in particular screwed, to one of the sides aa, bb of the wall 1.

[0044] The feedthrough device 10 comprises, in addition to the first plug-in element 100 and the feedthrough arrangement 300, a first spacer arrangement 400 and a first adapter element 500. The feedthrough arrangement 300 is designed, by way of example, such that it can be arranged on a wall 1 and provides a feedthrough through the wall 1. The one-piece design makes the connection particularly simple and, at the same time, watertight. The first plug-in element 100 is located in Figure 1a on a first side 1a of the wall 1 and is designed, by way of example, like the first plug-in element 100 according to the first embodiment. In this respect, reference is made to the description from the first embodiment. An embodiment according to the second embodiment is conceivable and possible for the first plug-in element 100 according to the third embodiment.

[0045] In Figures 3a to 3c, a second plug-in element 200 is further arranged on a second side lb of the wall 1. The second plug-in element 200 is designed in the same way as the second plug-in element 200 according to the first embodiment. In this respect, reference is made to the description in the first embodiment. An embodiment according to the second embodiment is conceivable and possible for the second plug-in element 200 according to the third embodiment.

[0046] In Figure 11, the first plug-in element 100 and the second plug-in element 200 are in a final state in which the first plug-in element 100 is in contact with the feedthrough arrangement 300. More precisely, in this final state, an end section of the first plug-in element 100 rests against an outer section of the feedthrough arrangement 300. According to the first embodiment of the feedthrough device 10, the first spacer arrangement 400 is configured such that, in this final state, the first adapter element 500 connected to the first spacer arrangement 400 passes through the feedthrough arrangement 300. Consequently, the first adapter element 500 protrudes at least partially from the feedthrough arrangement 300. More precisely, at least a front section of the first adapter element 500 protrudes from the feedthrough arrangement 300 on the second side 1b of the wall 1.

[0047] As described, a plug insert 120 is formed on the first adapter element 500 as an example. More precisely, a plug insert 120 is formed on the front section of the first adapter element 500 that protrudes from the feedthrough arrangement 300 as an example.

[0048] As described, the feedthrough device 10 according to the first embodiment further comprises a second plug-in element 200. As previously described, the first adapter element 500, connected to the first spacer arrangement 400, can pass through the feedthrough arrangement 300, and a front section of the first adapter element 500 can protrude from the feedthrough arrangement 300. This enables contact between the first adapter element 500 and the second plug-in element 200. For this purpose, a mating plug insert 220, corresponding to or complementary to the plug insert 120 of the first adapter element 500, is provided or arranged on the second plug-in element 200.When the second plug-in element 200 is brought into a final state in which the second plug-in element, more precisely a front section of the second plug-in element 200, rests against an outer section of the feedthrough arrangement 300 on the second side lb of the wall 1, a connection is established between the second plug-in element 200, more precisely a mating plug-in insert 220 provided in a front section of the second plug-in element 200, and the first adapter element 500, more precisely a plug-in insert 120 provided on the front section of the first adapter element 500, when the first plug-in element is also in its final state (see Figure 3d).

[0049] Furthermore, by way of example, one or more electrical conductors (not shown) are routed to the first adapter element 500 through the first spacer arrangement 400. When the second plug-in element 200 is connected to the first adapter element 500, a tight connection is thereby established between the second plug-in element 200 and the first plug-in element 100 through the wall 1.

[0050] The embodiments described herein offer several advantages. Firstly, a tight connection between the first plug-in element 100 and the second plug-in element 200 is enabled by the wall 1. Furthermore, standard plug-in housings and / or standard surface-mount housings can be used, which are pluggable from both sides 1a, 1lb of the wall 1. Special designs for plug-in housings and / or surface-mount housings can be used, but are not required. The length of the spacer arrangement(s) and / or the attachment of the adapter element(s) can be flexibly adapted to the thickness of the wall 1. The arrangement is fundamentally pluggable from both sides 1a, 1lb of the wall and is tight from both sides 1a, 1lb of the wall 1. Furthermore, only one electrical connection point is created, not at least two as in known solutions.In the described embodiments, the single electrical connection point is formed by connecting the first adapter element 500 and the second connector element 200 (first embodiment shown in Figures 1a to 11d and third embodiment shown in Figures 3a to 3d) or by connecting the first adapter element 500 and the second adapter element 700 (second embodiment shown in Figures 2a to 2d). A further advantage of the one-piece frame or feedthrough assembly according to the third embodiment is that only one sealing device is required and that the number of assembly interfaces can be further reduced compared to the two-piece version. This allows for cost reduction and a further decrease in assembly effort.
