Description

The invention relates to an electrical connection arrangement for a vehicle interior, a multi-layer arrangement for such a connection arrangement and a method for producing a connection arrangement and/or a multi-layer arrangement.

It is known to provide control elements in vehicle interiors by means of which a vehicle user can operate vehicle functions. The control elements can include, for example, pressure surfaces, push buttons, proximity sensors or rotary controls. Operation of the control elements can be detected electrically and in particular generate electrical signals that can be evaluated by a control device. For this purpose, the control elements can include sensors that detect the operation and then generate electrical signals.

US 2002/101738 A1 discloses an instrument panel for a vehicle trim part, which has a surface skin and an underlying foam layer. The foam layer has a first recess, wherein a switch for actuating a control is arranged in the first recess of the foam layer under the surface skin. The instrument panel has a rigid carrier layer and the foam layer is located between the surface skin and the carrier layer. The carrier layer has a second recess which adjoins the first recess, wherein the switch is partially located in the second recess and wherein the surface skin is flexible so that the switch can be actuated by pressing in the surface skin. Wiring of the switch is led to the switch from outside the instrument panel in a manner not explained in more detail and apparently runs largely freely and without separate structural support.

Typical target criteria when providing control elements in vehicles is reliable detection of the operation of the control element in a compact size. With previously known solutions, such as that of the US 2002/101738 A1 , this is not always achievable to the desired extent.

Reliable and compact electrical connections are also desirable for other electrical elements in the vehicle interior, such as other sensors or lighting devices.

It is therefore an object of the invention to improve the reliability of electrical connections near or in the area of vehicle interiors in a compact manner.

This object is achieved by the subject matter of the independent patent claims. Advantageous further developments are specified in this description, in the figures and in the dependent claims.

• - einer dem Fahrzeuginnenraum zugewandten formflexiblen ersten Lage;
• - einer formflexiblen dielektrischen Lage, zum Beispiel aus Kunststoff und insbesondere aus Polyvinylchorid (PVC);
• - wenigstens einer Leiterbahn, die auf einer ersten Seite der dielektrischen Lage aufgebracht ist und die einen elektrischen Anschlussbereich zur elektrischen Verbindung mit einer ersten Komponente aufweist;
• - wenigstens einer formflexiblen zweiten Lage, die an der erste Seite der dielektrischen Lage angeordnet ist und die Leiterbahn zumindest abschnittsweise überdeckt;

und wobei die Verbindungsanordnung ferner aufweist:

• eine elektrische Verbindungseinrichtung zur elektrischen Verbindung mit einer zweiten Komponente, wobei die Verbindungseinrichtung unter Durchdringung der zweiten Lage elektrisch leitend mit der Leiterbahn verbunden ist.

Accordingly, an electrical connection arrangement for establishing an electrical connection between at least two components in or near a vehicle interior is proposed, wherein the connection arrangement has a multi-layer arrangement (in other words: a multi-layer arrangement or a layered arrangement) with:

• - a first layer with flexible shape facing the vehicle interior;
• - a flexible dielectric layer, for example made of plastic and in particular of polyvinyl chloride (PVC);
• - at least one conductor track which is applied to a first side of the dielectric layer and which has an electrical connection region for electrical connection to a first component;
• - at least one dimensionally flexible second layer which is arranged on the first side of the dielectric layer and covers the conductor track at least in sections;

and wherein the connection arrangement further comprises:

• an electrical connection device for electrical connection to a second component, wherein the connection device is electrically conductively connected to the conductor track by penetrating the second layer.

At least one of the components can be operated from the vehicle interior, illuminate the vehicle interior, sense the vehicle interior or otherwise interact with the vehicle interior. An arrangement close to a vehicle interior (or adjacent to it) can be understood here as, for example, an arrangement on or in a trim part or another component adjacent to the vehicle interior. This can also be done without the corresponding component being directly accessible and in particular touchable from the vehicle interior. Instead, it can be separated from the interior by at least one layer and/or material layer.

The layers of the multilayer arrangement can be stacked and/or layered This can be done along a stack and/or layer axis. This can run orthogonal to a plane of the respective layers.

The layers can be generally flat and/or have a constant thickness. They can be flat layers or layers. Their thickness can, for example, be less than one tenth of the extension in a plane of a respective layer or layer. For example, the thickness can be less than one tenth of mutually orthogonal dimensions that span a plane of a respective layer or layer. This increases the compactness and can help to improve any desired backlighting or translucency or haptic properties (e.g. compliance) of the multilayer arrangement.

A form flexibility or, in other words, form slackness can be understood as meaning that a corresponding layer cannot independently maintain its shape (in particular under its own weight) without structural support from rigid components. On the other hand, a form rigidity or stiffness can be understood as meaning that a component can maintain its shape without structural support from other components (e.g. under its own weight or under a load that corresponds to a multiple of its own weight). The connection arrangement disclosed here can be form flexible in itself (or also as a whole), in particular whereby at least the multi-layer arrangement can be supported by a form-rigid support structure (e.g. of the type explained below).

The first layer can form an upper side of the connection arrangement. It can be touchable or generally accessible from the vehicle interior, for example. It can form or comprise a surface skin. It can be designed haptically and/or optically for user interactions, e.g. by means of a non-smooth structure.

The dielectric layer can be attached directly to the first layer, e.g. by printing, gluing or fusing. In particular, it can be attached to a side of the first layer facing away from the vehicle interior (for example with its second side). The dielectric layer can comprise a different material from the first layer and/or second layer. It can also have a decorative function, e.g. by being optically recognizable through an at least partially transparent first layer and/or by structuring the first layer at least in sections. According to one variant, the first layer is applied to the dielectric layer, for example as a final layer or layer. This can also include printing, gluing or fusing.

The dielectric layer can be opaque. It can have openings that serve to generate defined light patterns as a result of light shining through the openings. These light patterns can be visible through the first layer, which is semi-transparent, for example, and faces the vehicle interior. When the backlight is switched off, however, these openings may not be visible and/or at least difficult to recognize. The purpose of the light patterns can be to display symbols.

The openings can, in addition or alternatively, also serve other purposes, e.g. serve as a visual orientation aid, make embedded matrix displays visible and/or create light patterns for ambient lighting without symbol representation.

The dielectric layer can be produced in particular by a printing process, for example by screen printing or digital printing.

The at least one conductor track can also be flexible in shape. The conductor track can have a first end that is connected to the electrical connection area or includes it. It can have a second end that is connected to the electrical connection device. The conductor track can extend linearly, but not necessarily in a straight line, but rather, for example, at multiple angles and/or curves. In particular, the conductor track can extend linearly between a first and second end of the above type. Several conductor tracks can be provided, which can, for example, run parallel to one another at least in sections. The connection area to the first component and/or a connection area between the conductor track and the connection device can comprise a plurality of respective ends of the conductor tracks.

The at least one dimensionally flexible second layer can be arranged on a first side of the dielectric layer that faces away from the first layer. The dielectric layer and/or the at least one conductor track can be arranged, for example, between the first and the second layer, in particular viewed along a stack or layer axis of the multilayer arrangement. In other words, the dielectric layer and/or the at least one conductor track can be arranged in a sandwich-like manner between the first and the second layer and/or covered by them on both sides or shielded from the environment.

The electrical connection device can comprise at least one contact pin or contact pin, by means of which it can be connected to the conductor track in an electrically conductive manner. This contact pin or contact pin can have sharp edges. It can be passed through a closed (ie solid and/or continuous) region of the second layer. It can break through the second layer at least locally or, in other words, separate it locally.

The electrical connection device can be directly connected or connectable to the second component, for example because it is comprised by the second component (in particular because it is arranged in a housing thereof). The electrical connection device can be indirectly connected to the second component, for example because it comprises an interface (in particular physical and/or enabling a form-fitting connection) for connection to an electrical line that is connected or connectable to the second component.

The electrical connection device can be attached to the multi-layer arrangement, in particular mechanically attached and/or detachably attached. For example, it can be clamped to it, locked to it and/or connected to it by creating a positive connection.

According to one variant, the electrical connection device is or comprises a Flexible Printed Circuit (FPC) connector, in particular an FPC connector.

The disclosed connection arrangement enables a reliable contacting of the conductor track by the connecting device and thus a reliable electrical connection of the first and second components, since in particular the second layer can additionally support this contacting and/or the conductor track.

In particular, if, as is possible according to one embodiment, the connecting device applies significant forces to the conductor track to establish the contact, the second layer can provide a corresponding stabilizing effect for the conductor track. This can also apply during further operation and to vibrations and mechanical forces acting during this. The connecting arrangement can, for example, be designed to establish the electrical connection by establishing a crimp connection or another at least section-wise deformation of the conductor track.

Furthermore, the conductor track can also have a substantially two-dimensional and/or layer-like extension by being attached to the dielectric layer. It is preferably protected, guided and supported by the first and second layers and extends substantially within one of the layer planes of the multi-layer arrangement. This improves both the compactness of the connection arrangement and the reliability of the electrical connection produced thereby.

According to one embodiment, the second layer is at least partially translucent. For example, a translucency of at least 10%, preferably more than 25% and further preferably more than 50% of an incident light intensity can be provided. This improves the optional backlighting of the connection arrangement and in particular of the multi-layer arrangement. In general, the second layer can be transparent and/or colorless, wherein the transparency can in turn comprise a translucency according to any variant disclosed herein.

In a further development, the conductor track is printed onto the dielectric layer. For example, an electrically conductive ink can be used for this, which can be applied in particular by means of inkjet printing and/or screen printing and/or pad printing. The ink can, for example, be an ink containing silver, as is available at least in connection with screen printing and/or pad printing under the trade name "Silverink Dupont 603". Alternatively, the conductor track can be glued onto the dielectric layer or produced by means of other conductor track production methods, for example by means of photolithography.

However, printing in particular enables the precise creation of flexible and/or thin conductor tracks.

According to one aspect, the first layer comprises polyvinyl chloride (PVC). For example, it comprises plastisol, e.g. a PVC plastisol. By means of such a choice of material, the desired flexibility in shape can be ensured while at the same time providing sufficient resistance for use in vehicle interiors.

The first layer can be opaque at least in some areas. This can, for example, intentionally limit the visibility of the conductor tracks and/or the connection device from the vehicle user's perspective. According to preferred embodiments, however, the first layer is translucent. At least local opacity of the multi-layer arrangement can be produced by the dielectric layer, e.g. the variants discussed above regarding light patterns generated by this layer. The dielectric layer, which is opaque at least in some areas, Location can also intentionally limit the visibility of conductor tracks and/or other components from the vehicle user’s perspective.

In a further development, the second layer comprises polyvinyl chloride, plastisol (e.g. a PVC plastisol) and/or a similar polymer to the first layer. In particular, the first and second layers can be made of a similar material, for example both from a type of polyvinyl chloride or a type of plastisol, although their properties and/or optional material additives can optionally differ from one another. In principle, the first and second layers can also be made of an identical material.

By choosing similar or identical materials, the first and second layers can be matched to one another, for example in terms of their mechanical properties. This enables uniform protection and/or uniform support of the at least one conductor track by the first and second layers. It has been shown that this reliably prevents damage to the conductor tracks, particularly when establishing electrical contact with the connection arrangement.

According to one embodiment, a thickness and/or an elasticity of the first layer and the second layer differ from each other by no more than 25% or by no more than 10% or no more than 5%. The closer the thickness and/or elasticity of the first layer and the second layer are to each other, the more homogeneous the structural support of the at least one conductor track by these layers is.

The dielectric layer and/or the conductor track, on the other hand, can generally be less than half as thick (or less than a quarter as thick or less than a tenth as thick) as at least one of the first layer and the second layer. This increases the compactness of the multilayer arrangement. It has been shown that the dielectric layer and the at least one conductor track can reliably fulfill their respective functions even with a small thickness. On the other hand, an increased thickness of the first layer and/or the second layer improves the protection of the conductor track, in particular when the connecting device is attached to the multilayer arrangement.

The dielectric layer can also be produced by means of a printing process. For example, it can be made of a printable dielectric ink, in particular an opaque ink, and/or be generally opaque.

According to one variant, the first and/or the second layer are less than 1 mm or less than 0.5 mm thick. The dielectric layer and/or the conductor tracks can (additionally or alternatively) be less than 0.5 mm or less than 0.1 mm thick. It has been shown that the desired properties of the multi-layer arrangement can be satisfactorily achieved using these thicknesses (and in particular any combination thereof).

According to a further development, the second layer is formed homogeneously and/or closed before the electrical conductor track is connected to the electrical connection device, at least in the area in which the connection is to be made (for example in which the second layer is to be penetrated by the connection device). This simplifies the production of the second layer, so that it can be applied, for example, in one step and/or without separate local adjustments. Furthermore, this enables a locally very limited penetration, wherein the penetrating parts (for example optional contact pins) of the connection device can be enclosed by the second layer at least in sections. This improves the hold of the connection device on the multi-layer arrangement.

In a further embodiment, the connecting device has a first connecting section for connecting to the conductor track and a second connecting section which is electrically conductively connected to the first connecting section. For example, the first and second connecting sections can be enclosed by a common housing. They can face away from each other. For example, the first connecting section can face the multi-layer arrangement and the second connecting section can face away from the multi-layer arrangement. This enables a compact structure with improved accessibility of the connecting sections.

The second connection section can comprise an interface that is designed to produce an electrically conductive plug connection or another electrically conductive connection with a further connection device. The interface can enable a mechanical connection (in particular in addition to an electrical connection), in particular comprising the production of a positive connection and/or a latching connection. In this way, a component to be connected to the second connection section (in particular a line that is connected to the second component) can be reliably held at the interface.

According to a further embodiment, the first component comprises an operating element that can be operated by a vehicle occupant for operating a vehicle function (for example an air conditioning system, a seat adjustment, an infotainment system or a headlight adjustment). Alternatively or additionally, the first component can comprise a sensor, in particular for detecting an operation of an operating element (for example a pressure sensor or a proximity sensor) and/or for detecting a temperature or other states of the vehicle interior. Furthermore, additionally or alternatively, the first component can comprise a lighting device, for example for signaling a vehicle state and/or a state of a vehicle function that can be operated via an optional operating element.

The first component may be at least partially embedded in and/or attached to at least the first layer and/or the dielectric layer. Optionally, the connection arrangement disclosed herein may comprise the first component.

According to a further development, the second component comprises a control device. For example, the second component can comprise a printed circuit board (PCB) with a microcontroller. This microcontroller can comprise the control device or form it. The second component and in particular the control device can be positioned or positionable spatially separated from the multi-layer arrangement and/or the connecting device. However, an electrical connection to the spatially separated second component can be established by means of the connecting device, for example by means of at least one electrical line that runs between the connecting device and the second component. Optionally, the connecting arrangement disclosed here can comprise the second component.

It has been shown that such a merely indirect connection of the multi-layer arrangement to the second component is generally more reliable and has less of an impact on the desired shape flexibility of the multi-layer arrangement than a direct arrangement of the multi-layer arrangement on the usually dimensionally rigid second component. Although the connecting device can generally also be dimensionally rigid, its size is generally significantly smaller compared to preferred variants of the second component.

The invention also relates to a multilayer arrangement for an electrical connection arrangement according to any of the aspects disclosed herein.

The invention also relates to a component (e.g. a trim part) for a vehicle interior, having a connection arrangement according to any of the aspects disclosed here and a rigid support structure which supports at least the multi-layer arrangement (optionally also the connection device) at least in sections. The component can, for example, have a so-called soft skin and/or layered inner skin. It can be part of an instrument panel or center console. The component can generally comprise or form a surface facing a vehicle user. The component can conceal vehicle components located below this surface from the perspective of a vehicle user.

The invention also relates to a method, in particular for producing a multi-layer arrangement for an electrical connection arrangement which can be used to establish an electrical connection between at least two components in or near a vehicle interior, the method comprising:

• - applying a conductor track to a first side of a dimensionally flexible dielectric layer;

In particular, the method can be designed or developed in such a way that a multi-layer arrangement and/or a connection arrangement according to any of the aspects disclosed here can be produced with it.

Embodiments of the invention are explained below with reference to the accompanying schematic figures.

• 1 shows a schematic representation of a connection arrangement according to an embodiment of the invention in plan view.
• 2 shows a cross-sectional view of 1 .

1 shows a plan view of a connection arrangement 10 according to an embodiment of the invention, wherein a second layer 12 of a multi-layer arrangement 14 of this connection arrangement 10 faces the viewer. The second layer 12 is translucent and in particular transparent, so that an internal conductor track arrangement 16 with only two individual conductor tracks 18 can be seen. The conductor track arrangement 16 is, as will be explained below with reference to 2 explained, arranged within the multilayer arrangement 14 and enclosed by its layers or, in other words, surrounded.

The conductor tracks 18 each comprise a first electrical connection region 20, for example having a locally enlarged area. An indicated first component 1 is connected to the first connection region 20, which can be operated from a vehicle interior and/or extends into it (for example by at least locally penetrating the first layer 11 explained below and the dielectric layer 32 of the multi-layer arrangement 14).

The conductor tracks 18 also each comprise a second electrical connection area 22 for connection to an electrical connection device 24. In the example shown, the electrical connection device 24 is an FPC connector (Flexible Printed Circuit Connector). This is attached to the multi-layer arrangement 14 by establishing a crimp connection with the conductor tracks 18. As shown, the connection device 24 covers the connection areas 22 so that, contrary to the merely schematic principle representation in 1 are not visible from the user's perspective.

The connecting device 24 has a connecting section 26 that faces the multi-layer arrangement 14. It also has a connecting section 28 that includes a mechanical and electrical interface (not shown separately) for establishing an electrically conductive plug connection. This further connecting section 28 points away from the multi-layer arrangement 14 (in the example shown laterally). Furthermore, an electrical line 3 is attached to the latter for connection to a second component 2 according to any embodiment described herein. 2 shows a cross-sectional view along the section axis AA from 1 . Consequently, 2 the structure of in particular the multilayer arrangement 14 from 1 The multi-layer arrangement 14 is part of an interior trim part 36 and is attached, for example, to a partially shown dimensionally stable support structure 35 of this interior trim part 36.

The multi-layer arrangement 14 comprises a plurality of layers 11, 12, 32 explained below, which each run orthogonally to a stacking axis S and are stacked one on top of the other along the stacking axis S. Thickness dimensions of the layers 11, 12, 32 are each measured along the stacking axis S.

The multi-layer arrangement 14 comprises a first layer 11, which faces a vehicle interior 34 not shown elsewhere. The first layer 11 is made of a PVC plastisol to which opaque and, for example, black-colored particles are added. An exemplary thickness of the first layer 11 is less than 0.5 mm, e.g. 0.25 mm.

A dielectric layer 32 is attached and, for example, printed on the first layer 11, more precisely on a side thereof facing away from the vehicle interior 34. The dielectric layer 32 is less than a quarter as thick as the first layer 11, e.g. not more than 0.02 mm.

On a side facing away from the first layer 11, the dielectric layer 32 has the conductor track arrangement 18. This is also printed on and is less than a quarter as thick as the first layer 11, e.g. no more than 0.02 mm. The second layer 12 is also arranged on this side of the dielectric layer 32 and secured thereto, e.g. by melting or gluing. The second layer 12 is made of the same PVC plastisol as the first layer 11, but without added opaque and, e.g. black-colored particles. The second layer 12 is preferably translucent.

The conductor track arrangement 18 is arranged between the first layer 11 and the second layer 12, viewed along the stack axis S, and is completely enclosed by them (or, in other words, supported or embedded over their entire surface). The first and second layers 11, 12 are closed and solid and preferably homogeneous, at least before being connected to the connecting device 24.

The connecting device 24 has at least two contact pins 30. These are deformed during crimping in such a way that they are pressed through the second layer 12 into contact with a respective conductor track 18 or its connection area 22. The conductor track arrangement 18 is stabilized against the forces acting in this process by the sandwich-like receptacle between the first and second layers 11, 12 and is protected, for example, from cracking. In this way, the connecting device 24 is secured to the multi-layer arrangement 14 in a mechanically and electrically conductive manner.
