Description

Technical Field

[0001] The present invention relates to the field of mechanical and electrical contacting. It relates to 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 electric vehicles). In particular, the invention relates to a fastening system for integrating a flexible conductor section onto a component (in particular a charging socket) of a rigid conductor. Background Art

[0002] In electric vehicles, an electrical connection must be established between the traction battery and the charging socket for charging the traction battery. Depending on the installation location of the battery and charging socket, as well as the conditions within the vehicle interior, the required current rail (typically consisting of at least two or more conductors, typically rigid conductors) must bridge a certain distance within the vehicle. This current rail can bend and twist before being connected to the charging socket. During vehicle movement, or even during assembly, mechanical stress can already occur at the contact points between the rigid conductors (i.e., the current rail) and the charging socket. This can lead to premature damage and / or loosening of the electrical contacts and, consequently, associated subassemblies, and thus, malfunctions within the vehicle's charging system. Summary of the Invention

[0003] The object of the present invention is therefore to provide a solution for simple and fail-safe contacting of a rigid conductor, in particular a current rail, with a connecting component, in particular a charging socket for charging an electric vehicle, without the aforementioned disadvantages occurring.

[0004] The technical solution according to the present invention is based on the concept of connecting electrical contacts (e.g., DC contacts on a charging socket) to rigid conductors (e.g., current rails in an electric vehicle's charging path (e.g., HVDS, High Voltage Dual Rail)) in a force-free manner. To this end, flexible, bendable conductors are integrated at the ends or at the contact points.

[0005] In order to prevent the components connected to the flexible conductor from being in an undefined position depending on the integration point of the flexible conductor, the present invention proposes a retaining system or contact system that enables force-free contacting of the flexible conductor and thus ensures simple and fail-safe contacting of the rigid conductor with the connection component.

[0006] In this contact system, a connection retention element is located between one end of a rigid conductor and the (connection) component. A flexible conductor is integrated almost parallel to the rigid conductor end and the (connection) component itself to ensure force-free contact. The retention element itself has soft parts on one or both sides to accommodate tolerances (translation and / or rotation).

[0007] This contact system separates the "strain relief" function from the plug-in system itself. It enables integration with rail retaining elements.

[0008] According to a first aspect, the above technical problem 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 an electric vehicle), wherein the contact system includes: a rigid conductor, which is designed to conduct a charging current for charging the electric vehicle; a connecting component, in particular a charging socket, for electrically connecting to the rigid conductor and providing the charging current; a flexible conductor part, which is used to electrically connect the rigid conductor to the connecting component; and a retaining element, which is used to hold the rigid conductor and the connecting component and thereby hold the flexible conductor part in a force-free manner.

[0009] This contact system allows for simple and fail-safe contacting of rigid conductors (e.g., current rails) with connection components (e.g., charging sockets). It protects the contact points between the rigid conductors and the charging socket from mechanical stress when the vehicle is in motion. This prevents premature loosening of the electrical contacts and the resulting malfunctions in the vehicle's charging system.

[0010] According to an exemplary embodiment of the contact system, the retaining element comprises a first portion surrounding and holding the rigid conductor, a second portion attached to the connecting part, and a retaining arm fixing the position of the first portion and the second portion relative to each other.

[0011] The construction of this retaining element allows the function of "relieving strain" to be separated from the function of "insertion".The retaining element can be designed according to the requirements for the contact of the rigid conductor with the connection part.

[0012] According to an exemplary embodiment of the contact system, the first part has a flexible component which is designed to enable a relative movement between the rigid conductor and the holding arm.

[0013] In this way, the rigid conductor can be moved flexibly within the holding element and have tolerances in order to compensate for forces acting thereon without causing stress to the flexible conductor part.

[0014] According to an exemplary embodiment of the contact system, the flexible component of the first part comprises a soft component, which is formed in a region of the first part adjacent to the rigid conductor and preferably completely surrounds the rigid conductor, wherein the soft component is compressible and stretchable to enable relative movement between the rigid conductor and the retaining arm.

[0015] Due to the flexible component surrounding the rigid conductor, the rigid conductor can move freely within the first part of the retaining element within the limits predetermined by the structural form of the retaining element and thus compensate for forces acting on the rigid conductor without causing stress at the connection point between the rigid conductor and the flexible conductor part and thus causing forces to act on the flexible conductor part.

[0016] According to an exemplary embodiment of the contact system, the second part has a flexible component which is designed to enable a relative movement between the connecting component and the holding arm.

[0017] The connecting component or the charging socket can thus be moved flexibly within the second portion of the retaining element and have tolerances in order to compensate for forces acting thereon without loading the flexible conductor portion.

[0018] According to an exemplary embodiment of the contact system, the flexible component of the second portion comprises a soft component designed to enable a twisting of the connecting component relative to the retaining arm.

[0019] Due to the flexible part, the connecting part or the charging socket can move freely in the second part of the retaining element within the limits predetermined by the structural form of the retaining element and thus compensate for forces acting on the connecting part without causing stress on the connection point between the connecting part or the charging socket and the flexible conductor part and thus without causing forces to act on the flexible conductor part.

[0020] According to an example embodiment of the contact system, the flexible component of the second portion includes one or more material voids that enable the flexible component to be torsionally, stretched, and compressed.

[0021] These material recesses increase the flexibility of the flexible component and thus increase its range of movement.The material recesses are also easy to produce, for example using injection molding methods.

[0022] According to an exemplary embodiment of the contact system, the flexible component of the second portion comprises a laminate stack, which enables the flexibility of the flexible component.

[0023] This laminated stack, like the material voids, increases the flexibility of the flexible component and thus its range of motion.The laminated stack is also easy to manufacture.

[0024] According to an exemplary embodiment of the contact system, the holding arm has a flexible part designed to enable a relative movement between the first part and the second part of the holding element.The flexible part can, for example, be formed in the center of the holding arm.

[0025] Therefore, the holding arm can also have a certain flexibility and does not have to be designed to be rigid. Therefore, the holding arm can absorb and compensate for vibrations that occur.

[0026] According to an exemplary embodiment of the contact system, the contact system comprises a mounting element which is fixed to a holding element, said mounting element being designed to position and fix the contact system at an installation location in the electric vehicle.

[0027] The contact system can thus be positioned and fixed simply and efficiently at the corresponding installation location in the vehicle.

[0028] According to an exemplary embodiment of the contact system, the contact system comprises a flexible housing which accommodates and seals a flexible conductor portion and corresponding connections of the flexible conductor portion to a rigid conductor and a connection component.

[0029] The flexible housing, which can be constructed as a plastic film, for example, seals the contact system from external environmental influences such as dirt and moisture. This allows the housing to prevent corrosion of the conductive components.

[0030] According to a second aspect, the above technical problem is achieved by a method for manufacturing a contact system for mechanically and electrically contacting a rigid conductor (especially a high-voltage double rail) with a connecting component (especially a charging socket for charging an electric vehicle), the method comprising the following steps: providing a rigid conductor designed to conduct a charging current for charging an electric vehicle; providing a connecting component, especially a charging socket, for electrically connecting to the rigid conductor and providing the charging current; electrically connecting the rigid conductor to the connecting component via a flexible wire portion; and installing a retaining element for holding the rigid conductor and the connecting component, wherein the retaining element holds the flexible wire portion in a force-free manner.

[0031] This method allows for simple and fail-safe contacting of a rigid conductor, such as a current rail, with a connecting component, such as a charging socket. The contact system thus produced protects the contact points between the rigid conductor and the charging socket from mechanical loads during vehicle movement, thus preventing premature loosening of the electrical contact and any resulting malfunctions in the vehicle's charging system.

[0034] In the detailed description below, reference will be made to the accompanying drawings, which form part of this specification and show specific embodiments in the drawings to illustrate how the present invention may be implemented. It should be understood that other embodiments may be used and structural or logical changes may be made without departing from the scope of the present invention. Therefore, the following detailed description should not be considered restrictive. It should also be understood that, unless expressly stated otherwise, the features of the different embodiments described herein may be combined with each other.

[0035] Various aspects and embodiments are described with reference to the accompanying drawings, in which identical reference numerals generally indicate identical elements. In the following description, many specific details are set forth for explanation purposes to fully understand one or more aspects of the present invention. However, it will be appreciated by those skilled in the art that one or more aspects or embodiments can be implemented with a lower degree of specific details. In other cases, for ease of describing one or more aspects or embodiments, known structures and elements are illustrated in schematic form. It will be appreciated that other embodiments can be used and structural or logical changes can be made without departing from the present invention.

[0036] Figure 1 In a first perspective, a three-dimensional illustration of a contact system 100 according to a first embodiment for mechanically and electrically contacting a rigid conductor 110 with a connecting element 120 is shown. The first perspective is a side view, in which an observer observes the contact system 100 from above. Figure 2 In a second viewing angle, a three-dimensional representation of the same contact system 100 is shown. The second viewing angle is also a top view, wherein the observer observes the contact system 100 from obliquely above.

[0037] exist Figure 1 and Figure 2 The illustrated contact system 100 serves to mechanically and electrically connect a rigid conductor 110 , for example a high-voltage double rail, to a connecting component 120 , for example a charging socket for charging an electric vehicle.

[0038] However, the rigid conductor 110 does not have to be a high-voltage double rail; the rigid conductor 110 may also include other rigid conductors. For example, the rigid conductor 110 may also include a coaxial wire or other types of wires for guiding current.

[0039] Electrical conductors are used for wiring and connecting electrical components. Electrical conductors can be subdivided into flexible conductors and rigid conductors (or conductors or conductor sections). Rigid conductors are typically single-wire, solid conductors used for fixed installations, while flexible conductors are typically flexible, thin-core conductors used for movable installations. Rigid conductors are used in fixed (i.e., fixed-position) electrical devices. Flexible conductors cannot be installed flexibly, as this would cause the rigid conductor to break. Therefore, rigid conductors are well-suited for fixed installations in buildings or within vehicle bodies. Flexible conductors, on the other hand, are suitable for movable electrical devices whose position can be changed. The cross-sectional area of ​​electrical conductors (i.e., rigid and flexible conductors) is primarily determined by the loads to be borne by the conductors and the method and location of their installation.

[0040] The contact system 100 includes a rigid conductor 110 designed to conduct a charging current 121 for charging an electric vehicle. The contact system 100 also includes a connecting component 120, in particular a charging socket, for electrically connecting to the rigid conductor 110 and providing the charging current 121. The contact system 100 includes a flexible conductor section 140, which electrically connects the rigid conductor 110 to the connecting component 120. The contact system 100 also includes a retaining element 130, which holds the rigid conductor 110 and the connecting component 120 in place and thereby keeps the flexible conductor section 140 free of stress.

[0041] The term "free from stress" herein means that the flexible conductor portion 140 can freely move between the rigid conductor 110 and the connecting component 120 within the space predetermined by the extension of the retaining element 130, without external forces acting on the flexible conductor portion 140. These external forces are absorbed by the retaining element 130, so that the flexible conductor portion remains free from stress.

[0042] The flexible conductor portion 140 may be, for example, a bendable conductor or a round conductor. For example, the flexible conductor portion 140 may be constructed from a plurality of core wires, for example, twisted together, to obtain corresponding flexibility or bendability.

[0043] Bendable components, also called dimensionally unstable, shape-shifting or non-dimensionally stable components, are characterized by a low modulus of elasticity, low tensile stiffness and therefore large deformations even under low forces and moments.

[0044] The flexible conductor segments 140 can be connected to the contacts of the connecting element 120 and the corresponding contacts of the rigid conductor 110 or the individual rails of the high-voltage double rail, for example, by a suitable connecting method (e.g., welding, crimping, or gluing). The connecting can be performed, for example, using laser welding or ultrasonic welding.

[0045] As in Figure 1 and Figure 2 As shown in FIG, the holding element 130 includes a first portion 130a that surrounds and holds the rigid conductor 110; a second portion 130b that is attached to the connecting element 120; and a holding arm 130c for holding the first portion 130a and the second portion 130b in a fixed position relative to each other.

[0046] The first portion 130 a may be designed to be seat-shaped such that it forms a seat for the rigid conductor 110 to embed or enclose the rigid conductor therein.

[0047] The second portion 130b may be designed in a disk or plate shape so that it forms a disk or plate suitable for being fixed on the connection component 120 or the charging socket. For example, the second portion 130b may be bonded to the connection component 120 or welded to the connection component 120 or contact the connection component 120 in other ways. However, the second portion 130b may also have a shape similar to that in the Figure 1 and Figure 2 For example, the second portion 130b may be shaped similarly to the first portion 130a, ie, shaped like a socket to surround or embed the base of the connecting component 120.

[0048] The retaining arm 130c is used to keep the first portion 130a and the second portion 130b fixed relative to each other. The retaining arm 130c is formed of, for example, a rigid material, which may optionally have a reinforcement portion or a support to give the retaining arm 130c better strength or rigidity. Figure 1 and Figure 2 Only one retaining arm 130c is shown in FIG. However, there may be multiple retaining arms 130c, such as two, three, four or more, for holding the first portion 130a and the second portion 130b in a fixed position relative to each other.

[0049] The first portion 130a of the retaining element 130 may have a flexible component 131, as in Figure 1 and Figure 2As shown, the flexible member 131 is designed to enable relative movement between the rigid conductor 110 and the retaining arm 130c.

[0050] The flexible component 131 of the first portion 130a may, for example, include a soft component formed in the area of ​​the first portion 130a adjacent to the rigid conductor 110 and completely surrounding the rigid conductor 110, as in Figure 1 and Figure 2 The flexible member can be compressed and expanded to achieve relative movement between the rigid conductor 110 and the retaining arm 130c.

[0051] The second portion 130 b of the retaining element 130 may have a flexible component 133 designed to enable relative movement between the connecting component 120 and the retaining arm 130 c.

[0052] The holding arm 130 c may also partially have, for example, a flexible part 133 similar to the part 130 b or may have the flexible part 133 alone.

[0053] The flexible member 133 of the second portion 130b may comprise a soft member designed to enable twisting of the connecting member 120 relative to the retaining arm 130c. In addition to twisting, the soft member may also allow compression or extension, i.e., lateral movement of the connecting member 120 relative to the retaining arm 130c within the limits predetermined by the structural shape of the retaining element 130.

[0054] The flexible component 133 of the second portion 130b may include one or more material voids 135, such as in Figure 1 and Figure 2 As shown, the material voids enable torsion, extension, and / or compression of the flexible member 133 .

[0055] The flexible component 133 of the second portion 130b may also include Figure 1 and Figure 2 The laminated sheet shown in FIG. 1 realizes the flexibility of the flexible component 133 .

[0056] exist Figure 1 and Figure 2 The contact system 100 shown in FIG. 1 mainly consists of four elements: a rigid conductor 110 (here a high-voltage double rail), a component 120 to be connected to the rigid conductor 110 (here a charging socket), a flexible wire portion 140 located between the rigid conductor 110 (here a flexible round conductor) and the (connecting) component 120, and a holder 130 (or holding element 130) for holding the rigid conductor 110 and the connecting component 120.

[0057] The retaining element 130 is designed to ensure sufficient flexibility, depending on the position, orientation, and properties of the flexible conductor section 140, to achieve force-free contact / connection between the rigid conductor 110 and the component 120 even during operation. In this example, the retaining element 130 is designed to completely surround the rigid conductor 110, which here consists of two poles (positive / negative; DC), but as described above, it has a flexible portion 131 facing the conductor 110 to enable relative movement between the rigid conductor 110 and the support arm 130c.

[0058] The same principle, i.e. the integration of the flexible portion or flexible member 133, is also used in the second portion 130b of the bracket 130 for the contact member, i.e. the connecting member 120, as in Figure 1 and Figure 2 As shown in the figure.

[0059] Flexibility can be achieved by selecting the appropriate material (particularly Shore hardness) and the type of integration (i.e., placement and, for example, rotational engagement, i.e., form-fitting, force-fitting versus integration, particularly material-bonded integration), as well as by the design (i.e., structure or design) itself. For example, continuous gaps (holes) or material gaps 135 are integrated here, which, for example, allow the flexible component to be twisted, but also facilitate stretching and compression. Another design for the flexible component is, for example, a laminated stack.

[0060] The position and shape of the holding arm 130c are only examples. Figure 2 While the illustrated position of the retaining arm 130c employed herein is on the right side of the component 120, other positions and relative positions are also possible. Equally, the retaining arm 130c itself may also have a flexible portion or flexible section.

[0061] The decisive factors here are primarily the available space, the tolerances to be expected and compensated, and the desired or necessary overall stability of the system.

[0062] Also visible is an extension of the system 100 with a flexible housing 150, as shown in FIG. Figure 3 、 Figure 4 and Figure 5 As shown in FIG, the housing 150 surrounds at least the exposed portion of the rigid conductor 110 (here: the contact of the flexible conductor 140 or the conductor portion 140 to the rigid conductor 110, and a portion of the rigid conductor 110 itself) and the region to be contacted by the component 120, so that a complete sealing of the system can be achieved here.

[0063] While not shown here in combination with other high-voltage safety components (e.g., a high-voltage interlocking device), such high-voltage safety components may be integrated into one or both sides of the flexible housing 150, such as at an edge of the flexible housing 150, so that the circuit is interrupted when the housing 150 is pulled out from one or both sides.

[0064] This can be accomplished, for example, by supplementing it with a bracket or mounting plate 134 (as in Figure 5 The function of the holding arm is expanded in a manner as shown in FIG. 1 , so that the rigid conductor 110 can be positioned or fixed in an installation position for operation.

[0065] Figure 3 In a first perspective, a three-dimensional illustration of a contact system 100 according to a second embodiment for mechanically and electrically contacting a rigid conductor 110 with a connecting element 120 is shown. The first perspective is a front view of the contact system 100 from the front.

[0067] This sleeve or flexible housing 150 accommodates the flexible conductor section 140 and its corresponding connections to the rigid conductor 110 and the connection member 120 and seals them from environmental influences. The flexible conductor section 140 can move freely within the housing 150 .

[0070] Mounting element 134 can be fixed to retaining element 130 and is designed to position and secure contact system 100 at its installation location in the electric vehicle. Mounting element 134 can be, for example, a mounting plate with holes for securing the contact system to a corresponding position within the vehicle interior space via screws or other means. Mounting element 134 can be glued or welded to retaining element 130.
