[0002] In vehicles, there is a need to individually provide or arrange various devices within the interior. Such devices can also be referred to as modules. A module fulfills at least one specific function. For example, a module could be a reading lamp, which is to be positioned in the vehicle interior. A module could also be a coat hook, intended for hanging clothes in the vehicle interior. Many of these modules have an electrical or electronic function, so a power or data connection to the vehicle is required for the module to operate. Solutions exist in the form of various connectors that allow such modules to be positioned in the lower area of ​​the vehicle interior, for example, on a center console. There are also solutions where modules are arranged on surrounding rails.These solutions are usually visually conspicuous and, as visible connections, disrupt the overall appearance of the vehicle interior.

These solutions include components integrated into the headliner that provide both mechanical fixation of the microphone and electrical connection to cables routed behind the headliner. However, these solutions are intended for one-time installation only, and the microphone cannot be removed from the headliner without damage.

[0004] US patent 2018 / 0323537A1 describes an electrical connector for a vehicle interior that is compatible with the known and standardized cigarette lighter connectors. This electrical connector comprises a variety of electrical contact elements, which have spring-loaded components for easy connection to a module. The electrical connector can be located in various places in the vehicle and protrudes visibly from the surface in which it is installed.

[0005] US 2018 / 0027689A1 describes a system for the movable mounting of a monitor, for example, on the headliner of a vehicle. The system comprises a rail and a monitor module, the monitor module being able to be attached to the rail in various positions and orientations. The system also includes electrical connections through which the monitor can be powered via the rail.

[0006] US patent 2024 / 0284598A1 describes an interface assembly designed for the adjustable arrangement of one or more sensors. The assembly comprises a movable element with a sensor that can be attached to a stationary substrate at various positions. The actual, current position of the movable element can be uniquely determined via a detection range.

[0007] US 5,624,266 A describes an electromechanical connection system for a vehicle load carrier. The connection system enables the mechanical attachment of a load carrier to the roof of a vehicle, and the system may further include elements for electrically connecting the load carrier to a power supply from the vehicle interior.

[0008] The object of the invention is to propose solutions that simplify the installation of different modules at various locations in a vehicle interior, whereby these solutions should blend visually into the appearance of the vehicle interior.

[0009] This problem of the invention is solved by a connection arrangement according to claim 1 and a method for the reversible assembly of a connection arrangement according to claim 5.

[0010] The connection arrangement according to the invention comprises a connection receptacle and a module.

[0011] The connection receptacle for a module in or on a surface component includes: - a surface component which has an outer surface and an inner surface opposite the outer surface, - at least one electrical connection located on the outside or between the outside and the inside, wherein the electrical connection is intended to establish an electrical connection with the module, - at least one fastening element which is arranged on the outside or between the outside and the inside, wherein the fastening element is intended to create a reversible force-fit and / or form-fit connection with the module, wherein the outside of the surface component defines an interface of the connection receptacle beyond which no part of the connection receptacle protrudes.

[0012] The connection receptacle is designed for attaching and / or connecting a module to or within a surface component. At least a portion of this surface component is part of the connection receptacle. The module itself is not a part or component of the connection receptacle. A surface component is defined as a component that forms a visible surface in a vehicle or within a building. This surface component can be made of various materials, such as plastic, composites with a fabric covering, sheet metal, wood, or similar materials. The surface component has an outer surface, which is visible in the application. This outer surface forms the visible surface of the surface component. Opposite the outer surface, the surface component has an inner surface.Furthermore, the connection receptacle comprises at least one electrical connection, which is arranged on the outside or inside of the surface component. Preferably, several electrical connections are provided. The electrical connection is provided for electrically contacting the connection receptacle with a module. The connection receptacle also comprises at least one fastening element, which is arranged on the outside or inside of the surface component. The fastening element can be of various designs and is provided for mechanical connection with a module. The fastening element can, for example, be magnetic or form-fitting. Preferably, several fastening elements are provided. The electrical connection and the fastening element can be arranged in a common plane.

[0013] According to the invention, the outer surface of the surface component defines an interface for the connection receptacle. This means that no part or component of the connection receptacle protrudes beyond this interface. The outer surface, or interface, can be flat or have a more complex shape and, for example, be curved about one or more axes. Because no part of the connection receptacle protrudes beyond the interface, the entire connection receptacle is flush with the outer surface or within the surface component and does not protrude beyond it.

[0014] The connector is flush with the outer surface of a surface component or completely integrated into it. This allows the connector to blend seamlessly into the surface component's appearance, making it virtually invisible. If the surface component is located inside a vehicle, the connector is hardly noticeable. The connector can be integrated into various surface components located in different areas of a vehicle interior. For example, it can be integrated into the headliner of a vehicle, providing a reversible mounting option for a module.

[0015] In one embodiment of the connector receptacle, the receptacle has a cavity located between the outer and inner surfaces of the surface component, with the electrical connection and the fastening element being arranged on or in a surface of the cavity. In this embodiment, a cavity is provided which is located inside the surface component. This cavity serves to accommodate at least a portion of the module when the connector receptacle is connected to a module. The cavity can have different shapes and, for example, be cuboid. An opening is located on the outer surface, which allows access to the cavity. However, it is also possible that at least a portion of the cavity is formed by an undercut that is not directly accessible from outside the surface component in a linear movement perpendicular to the outer surface.The electrical connection and fastening element are arranged at least partially or entirely on or in a surface of the cavity. For example, the connection to the fastening element can be arranged on or in an inner surface of the cavity that runs parallel to the outer surface.

[0016] In a further embodiment, the surface component is formed by a section of a vehicle's headliner and / or has multiple electrical connections, in particular wherein each electrical connection comprises an electrically conductive, stationary contact pad or a resiliently mounted contact element. The surface component can be formed by a part of the vehicle's headliner. Alternatively, the surface component can also be formed by another component located in the vehicle's interior, for example, a center console, a dashboard, or the like. Preferably, the connection receptacle has multiple electrical connections. These can, for example, be designed as a simple, stationary contact pad that is not movable relative to its surroundings. Alternatively, an electrical connection can also comprise a resiliently mounted contact element.For example, spring-loaded contact pins are suitable designs or components for electrical connections. In such a spring-loaded contact pin, one contact element is spring-loaded relative to another section of the pin. The two sections are movable relative to each other against the spring force. These spring-loaded contact pins, also known as pogo pins, enable simple and reliable electrical connections, as the spring-loaded mounting allows for easy and reliable compensation of positioning tolerances between the terminal and a module.

[0017] In one embodiment, the fastening element includes a magnet or an undercut formed by a portion of the cavity. The fastening element can be designed in various ways and based on different physical principles. It is possible for the fastening element to include one or more magnets. Such a fastening element is designed for connection with a mating fastening element of a module, which also includes a magnet. The connection is then achieved through magnetic force. An advantage of this embodiment is that the connection can be established and separated by a simple linear movement. Furthermore, magnets can be used to adjust the relative positioning or orientation of the module for connection in a plane parallel to the outer surface.This ensures that the electrical connections of the terminal block are correctly connected to the corresponding electrical connections of the module. Alternatively, the fastening element can include an undercut formed by a portion of the cavity. Such an undercut represents a portion of the cavity that is not accessible through the opening in the cavity by linear movement in a direction perpendicular to the outside. The undercut can be used to insert a portion of the module's mating fastening element, thereby creating a positive fit in a direction perpendicular to the outside.

[0018] In a further embodiment, an additional fastening element is provided for creating a reversible force-fit and / or form-fit connection with the module, in particular wherein the additional fastening element comprises a magnet or an undercut formed by a portion of the cavity. In addition to the fastening element, a further additional fastening element may be provided, which is also intended for creating a reversible mechanical connection with a module. By additionally providing a further fastening element, the holding force of a module in the connection receptacle can be increased. The fastening element and the additional fastening element may be of the same or different design.For example, the fastening element may include a magnet, and the additional fastening element may include an undercut formed by a portion of the cavity. Alternatively, the fastening element may include an undercut, and the additional fastening element may include one or more magnets. Naturally, the additional fastening element and / or the fastening element may also be formed by other components that can be reversibly connected or disconnected from a corresponding counterpart. Such components could be, for example, hook-and-loop fasteners, snap fasteners, or similar devices.

[0019] The connection arrangement according to the invention of a module in or on a surface component comprises: - a connection fitting according to one of the previously described embodiments, - a module which has at least one counter-fastening element which is provided for the production of a reversible force-locking and / or form-locking connection with the fastening element or an additional fastening element of the connection receptacle, wherein in a connection state of the connection arrangement the counter-fastening element is reversibly connected to the fastening element or the additional fastening element and a part of the module rests against a part of the connection receptacle.

[0020] The connection arrangement according to the invention comprises a connector receptacle and a module which can be reversibly connected to and disconnected from the connector receptacle. "Reversible" in this context means that neither component is damaged during the connection process. Thus, the module can be connected to and disconnected from the connector receptacle multiple times. Furthermore, it is possible to insert the module into a different connector receptacle or to connect different modules to a single connector receptacle.

[0021] The module comprises at least one counter-fastening element, designed in such a way that it can be reversibly connected to a fastening element or an additional fastening element of the connector. In a connected state of the connection assembly, the module and the connector are connected to each other. In this state, at least a portion of the module rests against a portion of the connector. The module can be designed in various ways and, in a simple case, may consist merely of a cover that conceals the connector. Furthermore, the module can have a wide variety of functionalities.

[0022] The advantage of this connection arrangement is that a module can be easily connected to and disconnected from a connector. The connector itself is designed to be visually unobtrusive and blends seamlessly into its surroundings, such as a vehicle interior. When multiple connection arrangements are provided, they can be easily configured to allow different modules to be connected to different connectors. This enables modules to be used individually and as needed in various locations.

[0023] According to the invention, the connection receptacle has a cavity arranged between the outside and the inside of the surface component, wherein the electrical connection and the fastening element are arranged on or in a surface of the cavity, and the connection receptacle comprises several electrical connections, wherein the fastening element comprises a magnet, and the module has several electrical mating connections which are arranged on an outer surface of the module, and the mating fastening element comprises a magnet. wherein in the connection state of the connection arrangement the counter-fastening element is reversibly connected to the fastening element by magnetic force and the electrical connections are pressed against the electrical counter-connections by this magnetic force, whereby an electrical contact exists between the electrical connections and the electrical counter-connections, in particular wherein at least in some areas there is a positive locking in the circumferential direction about an imaginary axis which is oriented perpendicular to the outside.

[0024] In this embodiment, the module comprises several electrical mating connections which, when connected, are linked to the electrical connections of the terminal block. In this way, the module can have various technical functions and, for example, include a lamp, a loudspeaker, a microphone, or similar components. In this embodiment, both the fastening element and the mating element each include a magnet. Thus, the module can be easily and securely connected to the terminal block. The cavity and a portion of the module can be designed to be complementary in shape. This ensures that the module can only be connected to the terminal block in a specific relative orientation, thereby guaranteeing a correct connection between the electrical connections and their mating connections.Of course, the fastening element and the counter-fastening element can also be designed differently. However, the two elements are always designed so that they can be reversibly connected to each other.

[0025] According to the invention, the connection arrangement comprises several electrical connections, and the module has several electrical mating connections arranged on an outer surface of the module. At least one electrical connection comprises an electrically conductive, stationary contact pad, and at least one electrical mating connection comprises a resiliently mounted contact element. Alternatively, at least one electrical connection comprises a resiliently mounted contact element, and at least one electrical mating connection comprises an electrically conductive, stationary contact pad. In this embodiment, the connection receptacle and the module are connected to each other via several conductors. The contact pairing between an electrical connection and an electrical mating connection is configured such that one of the contact partners is formed by a conductive, stationary contact pad, and the other contact partner by a resiliently mounted contact element.In this way, tolerances present during the connection of the module to the terminal block during the creation of the electrical contact can be compensated for by the spring-loaded contact element. The spring-loaded contact elements can be arranged on either the terminal block or the module.

[0026] In a further embodiment, the connection receptacle has a cavity located between the outer and inner surfaces of the surface component, wherein the electrical connection and the fastening element are arranged on or in a surface of the cavity, and the connection receptacle comprises several electrical connections, wherein the fastening element comprises an undercut formed by a portion of the cavity, or an additional fastening element is provided for creating a reversible force-fit and / or form-fit connection with the module, wherein the additional fastening element comprises an undercut formed by a portion of the cavity, and the module has several electrical mating connections arranged on an outer surface of the module, and the mating fastening element comprises a locking mechanism.which is provided for reversible connection with an undercut of the cavity, wherein the locking mechanism comprises at least one latch which is movably mounted relative to the electrical mating terminals, in particular a spring-mounted latch, In the connected state of the connection arrangement, the counter-fastening element is reversibly connected to the fastening element or the additional fastening element by a positive fit, the locking bar engaging in an undercut of the cavity and a positive fit in the direction of an imaginary axis oriented perpendicular to the outside, and the electrical connections being pressed against the electrical mating connections by this positive fit, thereby establishing electrical contact between the electrical connections and the electrical mating connections, in particular, wherein at least in some areas a positive fit exists between the cavity and the module in the circumferential direction about an imaginary axis oriented perpendicular to the outside. In this embodiment, the module also comprises several electrical mating connections. Furthermore, in the connected state, a positive connection exists between the module and the connection receptacle.This positive-locking connection is achieved by a portion of at least one of the module's locking bars engaging in an undercut of the cavity of the terminal receptacle. Such a positive-locking connection results in a high holding force of the module in the terminal receptacle. It is possible to combine this embodiment with the previously described embodiment in which a fastening element and a counter-fastening element include a magnet. Furthermore, it is possible for the module to have no electrical counter-terminals and to be designed solely for mechanical functions, such as providing a hook for hanging clothes.

[0027] The module is designed to include at least one of the following components: a lighting device, a hook, a mirror, a screen, a cover, a camera, a microphone, a fan, a projector, an electrical charging port, a cup holder and / or a sun visor.

[0028] The object of the invention is finally achieved by a method for the reversible assembly of a connection arrangement according to one of the previously described embodiments, comprising the following method steps: A) Inserting and / or attaching the module to the connector, B) Establishing a reversible force-fit and / or form-fit connection between the fastening element or an additional fastening element of the connection receptacle and the counter-fastening element of the module.

[0029] The method according to the invention serves to establish the connection state of a connection arrangement. In a first process step A), the module is moved towards the connection receptacle and inserted into it or placed against it. In a second process step B), a mechanical connection is established between the fastening element or an additional fastening element and the mating fastening element. If the module and the connection receptacle have electrical connections or mating connections, an electrical connection between the module and the connection receptacle is established simultaneously with the mechanical connection. The method according to the invention makes it possible in a very simple manner to attach a module at a desired location where a connection receptacle is present.

[0030] Features, effects, and advantages disclosed in connection with the connection and the connection order are also deemed disclosed in connection with the process.

[0031] The invention is schematically illustrated with reference to embodiments in the drawings and is further described with reference to the drawings. The drawings show: Fig. 1 in a schematic, cutaway view an embodiment of a connection arrangement according to the invention, wherein the module is separated from the connection receptacle, Fig. 2 in a schematic, cutaway view the connection arrangement Fig. 1 in the connection state, in which the module is connected to the connector.

[0032] Fig. Figure 1 shows a schematic, cutaway view of an embodiment of a connection arrangement 100 according to the invention, wherein the module 2 is separated from the connection receptacle 1. The illustration above shows an embodiment of a connection receptacle 1, which is provided for connecting or receiving a module 2 shown below. The module 2 can be inserted into the connection receptacle 1 by a linear movement from bottom to top. The state in which the module 2 is inserted into the connection receptacle 1 is shown in Figure 1. Fig. 2 can be seen.

[0033] The connection receptacle 1 includes at least a portion of a surface component 3, which may, for example, be a section of a headliner in a vehicle. This surface component 3 has an outer surface 31 facing downwards and an inner surface 32 facing upwards. In the illustrated embodiment, a cavity 33 is arranged inside the surface component 3 between the outer surface 31 and the inner surface 32. In the illustrated embodiment, the connection receptacle 1 includes several electrical connections 4, which are arranged on a downward-facing surface inside the cavity 33. In the illustrated embodiment, each of the electrical connections 4 comprises an electrically conductive, stationary contact pad. These contact pads are immobile and have a downward-facing, substantially flat surface.The electrical connections 4 are connected to electrical conductors (not shown) which are routed through a portion of the surface component 3 on the side of the electrical connections 4 facing away from the cavity 33. Preferably, the electrical connections 4 are arranged regularly, for example in a row with constant intervals or in a matrix. In the illustrated embodiment, the connection receptacle 1 comprises two fastening elements 5, each containing a magnet. These fastening elements 5 are arranged adjacent to the electrical connections 4 on the downward-facing, inner surface of the cavity 33. Furthermore, the [component] in [the illustration] includes... Fig. Figure 1 shows two additional fastening elements 6, each comprising an undercut formed by a portion of the cavity 33. Both the fastening elements 5 and the additional fastening elements 6 are designed to create a reversible force-fit and / or form-fit connection with the module 2. The additional fastening elements 6 are optional and, in the illustrated embodiment, enable the module 2 to be reversibly fastened in the connection receptacle 1 with a high holding force. If less holding force is required, for example, with a lightweight module 2, the additional fastening element 6 can be omitted. Furthermore, the fastening element 5 can also have an undercut, or the additional fastening element 6 can have a magnet. For this reason, in Fig. 1 Both reference symbols 5 and 6 are shown both for the magnets arranged next to the electrical connections 4 and for the undercut in the cavity 33. In Fig. Figure 1 clearly shows that the outer surface 31 of the surface component 3 defines an interface for the connection receptacle. In the illustrated state or embodiment, the outer surface 31 limits the connection receptacle downwards. No part of the connection receptacle 1 protrudes beyond this interface. In this way, the connection receptacle is integrated into the surface component 3 in a visually unobtrusive manner.

[0034] The module 2 shown below is shaped such that it can be partially inserted into the connection receptacle 1. In the illustrated embodiment, the module 2 comprises two counter-fastening elements 25, each containing a magnet. These counter-fastening elements 25 are arranged on the upper end face of the module 2, the distance between the two counter-fastening elements 25 corresponding to the distance between the two fasteners 5, each containing a magnet, in the connection receptacle 1. The counter-fastening elements 25 are designed to create a reversible force-fit and / or form-fit connection with the fasteners 5. In the illustrated embodiment, the module 2 comprises several electrical mating connections 24, which are arranged on the end face of the module 2 between the two counter-fastening elements 25.These electrical mating terminals 24 are each provided for establishing an electrical connection with an electrical terminal 4 of the terminal receptacle 1. In the illustrated embodiment, each electrical mating terminal 24 comprises a spring-mounted electrical contact element. Each of these spring-mounted contact elements is linearly movable in a direction perpendicular to the outer surface 31 and is pressed towards the terminal receptacle 1 by a spring. The electrical mating terminals 24 can, for example, be formed by the male part of a pogo pin. Accordingly, the electrical terminals 4 can be formed by the female part of a pogo pin. The spring mounting of the contact elements ensures that a secure electrical connection is always present between an electrical terminal 4 and an electrical mating terminal 24 when the module 2 is connected to the terminal receptacle.In the illustrated embodiment, the module 2 comprises two differently designed counter-fastening elements 25. In addition to the counter-fastening elements 25 on the end face, each comprising a magnet, two further counter-fastening elements 25 are arranged laterally on the module 2, each comprising a locking mechanism 251. Each of these locking mechanisms 251 comprises a movably mounted latch 2511, which is spring-mounted and movable against a spring force in a direction parallel to the outer surface 31. A portion of these latches 251 is designed to be inserted into an undercut of the cavity 33. In the illustrated embodiment, the module 2 can thus be connected to the terminal receptacle 1 both by frictional locking via magnetic force and by positive locking via the latches 2511. In this way, a high holding force of the module 2 in the terminal receptacle 1 can be achieved.In the illustrated embodiment, module 2 comprises a lamp L, which is supplied with electrical energy via the electrical terminals 4. However, module 2 can also be configured differently. Furthermore, it is possible that the module has no electrical terminals 24 and is formed solely by a cover plate, which serves to close the terminal receptacle 1.

[0035] Fig. Figure 2 shows a schematic, cutaway view of the connection arrangement 100. Fig. 1 in the connection state, in which module 2 is connected to connector 1. In Fig. 2 is the same connection arrangement 100 as in Fig. 1 shown. Fig. However, in section 2, this connection arrangement 100 is in the connected state in which the module 2 is partially inserted into the connection receptacle 1 and connected to it. For details and explanations of the individual sections of the connection arrangement 100, please also refer to the description of Fig. 1 referred to, which also applies in the same way to Fig. 2 applies.

[0036] In the Fig. In the connection state shown in Figure 2, the counter-fastening elements 25 of module 2, each comprising a magnet and arranged on the end face, are force-fit and reversibly connected to the fastening elements 5 of the terminal receptacle. This force-fit connection is established by the magnetic force occurring between the magnets, which presses module 2 against the terminal receptacle 1. In the Fig. In the embodiment shown in Figure 2, the counter-fastening elements 25, each having a locking mechanism 251, are additionally connected in a form-fitting manner to the auxiliary fastening elements 6, which have an undercut. A portion of the locking bars 2511 engages in an undercut of the cavity 33. Through the connections between the counter-fastening elements 25 and the fastening elements 5 or auxiliary fastening elements 6, the module is pressed against the terminal receptacle 1 in a direction perpendicular to the outer surface 31. Simultaneously, the spring-loaded contact elements of the electrical mating connections 24 are partially pressed into the interior of the module 2. The resulting spring force presses the electrical contact elements with sufficient normal force against the electrical terminals 4, thus establishing a secure electrical connection. In the embodiment shown in Figure 2, the counter-fastening elements 25 and the fastening elements 5 and auxiliary fastening elements 6 are pressed against the terminals 4 with sufficient normal force. Fig.In the connection state shown in Figure 2, there is thus a force-fit and form-fit mechanical connection as well as an electrical connection between Module 2 and the terminal 1. The connection state can be easily and reversibly released by applying lateral pressure to the locking bars 2511, thereby releasing the form-fit between Module 2 and the terminal 1. Module 2 can then be pulled downwards in a direction perpendicular to the outer surface 31 until the magnetic force between Module 2 and the terminal 1 is released.
