Description

Technical FieldThe present invention relates to the field of mechanical and electrical contacting. The invention relates to a contact system for the mechanical and electrical contacting of a rigid conductor, in particular a high-voltage double rail, with a connecting component, in particular a charging socket for charging a battery-electric vehicle. The invention relates in particular to a holding system for components, in particular load cells, for integrating flexible line sections on rigid conductors.Prior ArtIn battery-electric vehicles, an electrical connection must be created between the battery and the charging socket in order to charge the traction battery. Depending on the installation location of the battery and charging socket and the circumstances in the interior of the vehicle, the busbar required for this purpose, usually consisting of at least two or more conductors, which is usually designed as a rigid conductor, must bridge a certain distance in the vehicle interior. The busbar can be bent and twisted before it is connected to the charging socket. During movements of the vehicle and also already during assembly, a mechanical load is thereby produced on the contact points between the rigid conductor, i.e. the busbar, and the contact points of the charging socket, which can cause early damage and / or detachment of the electrical contacts, and also subcomponents connected thereto, and thus faults in the charging system of the vehicle.U.S. Pat. No. 2023 0 415 590 A1 discloses a power supply device having a contact system of the generic type, and a housing is disclosed in WO 2015 060 103 A1. DE 10 2016 205 279 A1 discloses a connector. EP 2 808 951 A1 discloses a terminal strip for connection, and DE 10 2022 106 349 A1 discloses a line arrangement for an energy store of a motor vehicle.DESCRIPTION OF THE INVENTIONIt is therefore an object of the invention to provide a concept for simple and failsafe contacting of a rigid conductor, in particular a busbar, with a connecting component, in particular a charging socket for charging a battery-electric vehicle, in which the above-mentioned disadvantages do not occur.The object is achieved by the subject matter of the independent claim. Advantageous developments of the invention are specified in the dependent claims, the description and the accompanying figures.The solution according to the invention is based on the concept of connecting the electrical contacts, for example the DC contacts on a charging socket, without force to a rigid conductor, for example a busbar in the charging path (for example HVDS-high-voltage double busbar) of the battery-electric vehicle. In order to achieve this, flexible, flexurally slack conductors are integrated at the ends or in each case toward the contact points.In order to prevent the flexible conductors, depending on the integration point, from assuming undefined positions of the components connected to the flexible conductors, a holding system or contacting system is presented in this disclosure, which brings about force-free contacting of the flexible conductors and thus ensures simple and fail-safe contacting of a rigid conductor with a connecting component.In this contacting system, a connecting holding element is located from one end of a rigid conductor toward a (connecting) component. Between the end of the rigid conductor and the (connecting) component itself, quasi parallel, the flexible conductor is integrated for force-free contacting. The holding element itself has a soft component on one or both sides in order to create tolerances (translatory and / or rotatory).Such a contacting system offers decoupling the function "strain relief" from the plug-in system itself. A combination with a retaining element of a rail can be realized.According to a first aspect, the object described above is achieved by a contact system for mechanically and electrically contacting a rigid conductor, in particular a high-voltage double rail, with a connecting component, in particular a charging socket for charging a battery-electric vehicle, wherein the contact system comprises: a rigid conductor which is designed to conduct a charging current for charging a battery-electric vehicle; a connecting component, in particular a charging socket, for electrically connecting to the rigid conductor and for providing the charging current; a flexible line section which electrically connects the rigid conductor to the connecting component; and a retaining element which retains the rigid conductor and the connecting component and in the process retains the flexible line section in a force-free manner.Such a contact system allows simple and failsafe contacting of the rigid conductor, such as a busbar, with the connecting component, for example a charging socket. This contact system prevents mechanical loading of the contact points between the rigid conductor and the contact points of the charging socket occurring during movements of the vehicle. An early release of the electrical contacts is thus prevented and faults in the charging system of the vehicle caused thereby are avoided.According to an embodiment of the contact system according to the invention, the holding element comprises: a first portion which comprises and holds the rigid conductor, a second portion which is attached to the connecting component; and a holding arm which fixes the first portion to the second portion in relative position to one another.Such an embodiment of the holding element allows decoupling of the function "strain relief" from the function "plugging". The holding element can be designed according to the requirements for contacting the rigid conductor with the connecting components.According to an embodiment of the contact system according to the invention, the first section has a flexible component which is designed to enable a relative movement between the rigid conductor and the retaining arm.The rigid conductor can thus move flexibly within the holding element and has tolerances in order to compensate for forces acting on it without the flexible line section being subjected to load.According to an exemplary embodiment of the contact system, the flexible component of the first section comprises a soft component which is formed in a region of the first section adjoining the rigid conductor and preferably completely comprises the rigid conductor, wherein the soft component is compressible and stretchable in order to enable the relative movement between the rigid conductor and the holding arm.By means of the soft component which comprises the rigid conductor, the rigid conductor can move freely in the first section of the holding element within limits predetermined by the design of the holding element and thus compensate for forces acting on the rigid conductor without the connection points of the rigid conductor to the flexible conductor section being subjected to stress and thus a force acting on the flexible conductor section.According to an exemplary embodiment of the contact system, the second section has a flexible component which is designed to enable a relative movement between the connecting component and the holding arm.The connecting component or the charging socket can thus move flexibly within the second section of the holding element and has tolerances in order to compensate for forces acting on it without the flexible line section being subjected to load.According to an exemplary embodiment of the contact system, the flexible component of the second section comprises a soft component which is designed to enable the connecting component to be rotated with respect to the holding arm.By means of the soft component, the connecting component or the charging socket can move freely in the second section of the holding element within limits predefined by the design of the holding element and thus compensate for force effects on the connecting component without the connection points of the connecting component or charging socket to the flexible conductor section being subjected to stress and thus a force effect on the flexible conductor section.According to an exemplary embodiment of the contact system, the flexible component of the second section comprises one or more material recesses which enable both a twisting and a stretching and upsetting of the flexible component.These material recesses increase the flexibility of the flexible component and thus its range of movement. They can also be produced in a simple manner, for example by injection molding.According to an exemplary embodiment of the contact system, the flexible component of the second section comprises a lamella package, which enables the flexibility of the flexible component.This stack of lamellae increases the flexibility of the flexible component and thus its range of movement analogous to the material recesses. The stack of lamellae is also simple to produce.According to an exemplary embodiment of the contact system, the holding arm has a flexible component which is designed to enable a relative movement between the first section and the second section of the holding element. The flexible component can be formed, for example, in the middle of the holding arm.The holding arm can thus also have a certain flexibility and does not have to be rigid. It can thus absorb and compensate for oscillations that occur.According to an exemplary embodiment of the contact system, the contact system comprises a mounting element fastened to the holding element, which mounting element is designed to position and fix the contact system at a place of installation of the battery-electric vehicle.The contact system can thus be positioned and fastened easily and efficiently at the corresponding installation site of the vehicle.According to an exemplary embodiment of the contact system, the contact system comprises a flexible enclosure enclosing and sealing the flexible lead portion and respective connection portions of the flexible lead portion with the rigid conductor and the connection component.The flexible enclosure, which can be embodied, for example, as a plastic film, seals the contact system against external environmental influences, such as dirt and moisture. Corrosion of the electrically conductive components can be prevented with the housing.According to a second aspect, the object described above is achieved by a method for producing a contact system for mechanically and electrically contacting a rigid conductor, in particular a high-voltage double rail, with a connecting component, in particular a charging socket for charging a battery-electric vehicle, the method comprising: providing a rigid conductor which is designed to conduct a charging current for charging a battery-electric vehicle; providing a connecting component, in particular a charging socket, for electrically connecting to the rigid conductor and for providing the charging current; electrically connecting the rigid conductor to the connecting component by means of a flexible line section; and mounting a holding element for holding the rigid conductor and the connecting component, wherein the holding element holds the flexible line section free of force.Such a method allows simple and fail-safe contacting of the rigid conductor, such as a busbar, with the connecting component, for example a charging socket. The contact system produced in this way prevents mechanical loading of the contact points between the rigid conductor and the contact points of the charging socket occurring during movements of the vehicle, so that premature release of the electrical contacts can be prevented and faults caused thereby in the charging system of the vehicle can be avoided.Brief description of the FiguresThe invention is described in more detail below with reference to exemplary embodiments and the figures.

It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the concept of the present invention. The following detailed description is therefore not to be taken in a limiting sense. Further, it is to be understood that the features of the various embodiments described herein may be combined with each other, unless specifically stated otherwise.The aspects and embodiments will be described with reference to the drawings, wherein like reference numerals generally refer to like elements. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects of the invention. However, it may be apparent to one skilled in the art that one or more aspects or embodiments may be practiced with a lesser degree of the specific details. In other instances, well-known structures and elements are shown in schematic form to facilitate describing one or more aspects or embodiments. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the concept of the present invention.FIG. 1 shows a three-dimensional illustration of a contact system 100 for the mechanical and electrical contacting of a rigid conductor 110 with a connecting component 120 according to a first embodiment in a first perspective. The first perspective here is a side view in which the observer looks laterally at the contact system 100 from above. FIG. 2 shows a three-dimensional representation of the same contact system 100 from FIG. 1 in a second perspective. The second perspective here is likewise a plan view in which the observer looks obliquely from above onto the contact system 100.The contact system 100 illustrated in FIGS. 1 and 2 serves for the mechanical and electrical contacting of a rigid conductor 110, for example a high-voltage double rail, with a connecting component 120, for example a charging socket for charging a battery-electric vehicle.However, the rigid conductor 110 does not necessarily have to be a high-voltage double rail; other rigid conductors can also be included therein. For example, the rigid conductor 110 may also comprise a coaxial line for carrying current or another type of line.Electrical lines serve for the wiring and interconnection of electrical components. They can be divided into the flexible and rigid lines (or conductors or line sections). Rigid conductors are usually single-wire and solid and are intended for fixed laying, flexible lines are usually flexible fine-wire conductor lines for movable laying. Rigid conductors are used for fixed electrical installation. They must not be installed movably, since cables with rigid wires would otherwise break. Therefore, they are well suited for building installation or fixed installation inside the vehicle body. Flexible lines, on the other hand, are suitable for any mobile electrical installation. The line cross-sections of the electrical lines, i.e. the rigid conductors and the flexible lines, are dimensioned above all after the load to which the line is exposed and after how and where the line is laid.The contact system 100 comprises a rigid conductor 110 configured to carry a charging current 121 for charging a battery-electric vehicle. The contact system 100 further comprises a connection component 120, in particular a charging socket, for electrical connection to the rigid conductor 110 and for providing the charging current 121. The contact system 100 comprises a flexible line portion 140 electrically connecting the rigid conductor 110 to the connection component 120. The contact system 100 further comprises a holding element 130 which holds the rigid conductor 110 and the connecting component 120 and thereby holds the flexible line section 140 free of force.Force-free means here that the flexible line section 140 can move freely between the rigid conductor 110 and the connecting component 120 in a space predefined by the extent of the holding element 130, without external force effects acting on the flexible line section 140. These external forces are absorbed by the holding element 130 and absorbed by the latter, so that the flexible line section remains force-free.The flexible line section 140 can be, for example, a flexurally slack conductor or round conductor. It can be constructed, for example, from a plurality of wires which are arranged, for example, twisted with respect to one another in order to impart the corresponding flexibility or flexibility.Flexurally slack components, also referred to as dimensionally unstable, dimensionally unstable or non-dimensionally stable components, are characterized by a low modulus of elasticity, low elongation and therefore large deformations already as a result of low force and moment stress.The flexible line section 140 can be joined, for example welded or pressed or bonded, to the contacts of the connecting element 120 and to the corresponding contacts of the rigid conductor 110 or of the individual rails of the high-voltage double rail by a suitable joining method. The joining can be effected, for example, by laser welding or ultrasonic welding.As shown in FIGS. 1 and 2, the retaining member 130 includes a first portion 130 athat includes and retains the rigid conductor 110; a second portion 130 bmounted on the connecting component 120; and a retaining arm 130 cthat fixes the first portion 130 awith the second portion 130 bin relative position to each other.The first portion 130 amay be formed in a socket shape to form a socket for the rigid conductor 110 to sandwich the rigid conductor therein.The second section 130 bmay be disk-shaped or plate-shaped, so that it forms a disk or plate which is suitable for fastening to the connecting component 120 or the charging socket. For example, it may be adhered to the connector component 120, or welded or otherwise contacted with the connector component 120. However, the second portion 130 bmay also have a different shape than that illustrated in FIGS. 1 and 2. For example, the second portion 130 bmay be shaped similar to the first portion 130 a, i.e. as a socket which encloses or embeds the connection component 120 in a socket-like manner.The support arm 130c serves to maintain the first portion 130a and the second portion 130b in relative position to each other. It is formed of, for example, a rigid material, which may optionally include braces to provide the support arm 130c with improved rigidity. In FIGS. 1 and 2, only one holding arm 130 cis illustrated. However, a plurality of holding arms 130 cmay be provided, for example two, three, four or even more, which hold the first portion 130 aand the second portion 130 bin a relative position with respect to one another.The first portion 130 aof the support member 130 may include a flexible component 131, as shown in FIGS. 1 and 2, configured to allow relative movement between the rigid conductor 110 and the support arm 130 c.The flexible component 131 of the first portion 130 amay include, for example, a soft component formed in a region of the first portion 130 aadjacent to the rigid conductor 110 and fully including the rigid conductor 110, as illustrated in FIGS. 1 and 2. The soft component is compressible and stretchable to allow relative movement between the rigid conductor 110 and the support arm 130c.The second portion 130 bof the retaining element 130 may have a flexible component 133 which is designed to enable a relative movement between the connecting component 120 and the retaining arm 130 c.The holding arm 130 cmay have a flexible component 133 in sections, just like e.g. the section 130 b, or solely.The flexible component 133 of the second portion 130 bmay include a soft component configured to allow the connection component 120 to be rotated relative to the retaining arm 130 c. In addition to the twisting, the soft component can likewise permit compression or expansion, that is to say a transverse movement of the connecting component 120 with respect to the holding arm 130 c, within limits predefined by the design of the holding element 130.The flexible component 133 of the second portion 130 bmay include one or more material recesses 135, as illustrated in FIGS. 1 and 2, which enable both twisting and stretching and / or upsetting of the flexible component 133.The flexible component 133 of the second section 130 bmay also comprise a stack of lamellae, which is not shown in FIGS. 1 and 2 however, which allows the flexibility of the flexible component 133.The contact system 100 illustrated in FIGS. 1 and 2 fundamentally consists of four elements: the rigid conductor 110 (here the high-voltage double rail), the component 120 to be connected to the rigid conductor 110 (here the charging socket), the flexible line section 140 between the rigid conductor 110 (here the flexible round conductor) and the (connecting) component 120, and the holder 130 (or the holding element 130), which holds the rigid conductor 110 on the one hand, and also connects the component 120.The holder 130 is designed such that, depending on the position, orientation and properties of the flexible line section 140, sufficient flexibility is ensured, which also makes possible force-free contacting / connection of the rigid conductor 110 to the component 120 during operation. The holder 130, in the present example, is designed to fully include the rigid conductor 110, here consisting of two poles (plus / minus; DC), but to have a flexible component 131 towards the conductor 110 as described above, so as to allow relative movement between the rigid conductor 110 and the holder arm 130c.The same principle, namely the integration of a flexible portion or a flexible component 133, is also applied in the second section 130 bof the holder 130 to the contacted component, i.e. the connecting component 120 as illustrated in FIGS. 1 and 2.The flexibility is to be designed by the suitable choice of material (above all of the Shore hardness) and by the type of integration (i.e. set on and, for example, rotatable, i.e. positive locking, force locking and force locking integrated above all material locking) and by the configuration (i.e. the architecture or the design) itself. By way of example, continuous recesses (holes) or material recesses 135 are integrated here, which enable the soft component to be rotated, for example, but also promotes stretching and upsetting. Another design for the flexible component is, for example, a stack of lamellae.The position and shape of the holding arm 130 cis exemplary here. Analogous to the position of the holding arm 130 con the right side of the component 120 converted here, as shown in FIG. 2, any other positions and positions with respect to one another are possible. Likewise, the holding arm 130 cmay itself have a flexible portion.The decisive factor here is fundamentally the available package and also the tolerances to be expected and compensated, and the desired or necessary overall stability of the system.It is likewise possible to see the extension of the system 100 with a flexible enclosure 150, as illustrated in FIGS. 3, 4 and 5, which comprises the exposed part of the rigid conductor 110 (here: and the contacting of the flexible conductor 140 or line section 140 to the rigid conductor 110, and a part of the rigid conductor 110 itself) with the region of the component 120 to be contacted, at least in such a way that a seal of the system can be implemented here in its entirety.Not shown here is the combination with further high-voltage safety modules, such as an HV interlock. This can be integrated on one or both sides, for example, in the edge region of the flexible enclosure 150, with the result that the circuit is interrupted when the enclosure 150 is pulled off on one or both sides.The function of the holding arm can be extended, for example by means of a supplement with a type of holder or mounting plate 134, as shown in FIG. 5, as a result of which the rigid conductor 110 can then be positioned or fixed at the installation site for operation.FIG. 3 shows a three-dimensional illustration of a contact system 100 for the mechanical and electrical contacting of a rigid conductor 110 with a connecting component 120 according to a second embodiment in a first perspective. The first perspective here is a front view in which the observer looks at the contact system 100 from the front. FIG. 4 shows a sectional illustration of the same contact system 100 from FIG. 3 in a second perspective. The second perspective here is a side view in which the observer looks laterally at a section through the contact system 100.In contrast to the first embodiment according to FIGS. 1 and 2, the contact system 100 according to the second embodiment, as illustrated in FIGS. 3 and 4, additionally comprises a bushing 150 and a flexible housing 150, respectively.This grommet or flexible housing 150 houses and seals the flexible lead portion 140 and respective connection portions of the flexible lead portion 140 with the rigid conductor 110 and the connection component 120. The flexible lead portion 140 is free to move within the housing 150.FIG. 5 shows a three-dimensional representation of a contact system 100 for the mechanical and electrical contacting of a rigid conductor 110 with a connecting component 120 according to a third embodiment. In this illustration, the viewer looks at the contact system 100 from the front.In contrast to the second embodiment according to FIGS. 3 and 4, the contact system 100 according to the third embodiment, as illustrated in FIG. 5, additionally comprises a mounting element 150 or a fixing element 150 which is attached to the holding element 130.The mounting element 134 can be fastened to the holding element 130 and can be designed to position and fix the contact system 100 at a place of installation of the battery-electric vehicle. The mounting element 134 can be, for example, a mounting plate which has bores in order to fasten the contact system by means of screws or otherwise at a corresponding location in the vehicle interior. The mounting member 134 may be bonded or welded to the retaining member 130.FIG. 6 shows a schematic illustration of a method 600 for mechanically and electrically contacting a rigid conductor 110 with a connection component 120 according to an embodiment.The method 600 serves for producing a contact system 100, as described above with reference to FIGS. 1, 2, 3, 4 to 5, for the mechanical and electrical contacting of a rigid conductor 110, in particular a high-voltage dual rail, with a connecting component 120, in particular a charging socket for charging a battery-electric vehicle.The method 600 comprises providing 601 a rigid conductor 110 configured to carry a charging current for charging a battery-electric vehicle.The method 600 comprises providing 602 a connection component 120, in particular a charging socket, for electrical connection to the rigid conductor and for providing the charging current.The method 600 comprises electrically connecting 603 the rigid conductor 110 to the connection component 120 by means of a flexible line section 140.The method 600 comprises mounting 604 a retaining element 130 for retaining the rigid conductor 110 and the connection component 120, wherein the retaining element 130 keeps the flexible line section 140 force-free.LIST OF REFERENCE CHARACTERS100 Method according to the invention for mechanically and electrically contacting a rigid conductor with a connecting component 601 providing a rigid conductor 602 providing a connecting component 603 electrically connecting the rigid conductor with the connecting component 604 mounting the holding element 110 rigid conductor or busbar 120 connecting component or component 121 charging current 130 holding element or holder 130 afirst section of the holding element 130 bsecond section of the holding element 130 cholder arm of the holding element 131 flexible component of the first section of the holding element 133 flexible component of the second section of the holding element 134 mounting element or mounting plate 135 material recesses of the flexible component of the holding element 140 flexible line section or flexible round conductor 150 flexible housing or bushing 600 according to the invention
