Description

Technical field Embodiments of the present invention relate to an electrical connector and a method for manufacturing it. Preferred embodiments relate to a one-piece spring element that applies force to separate electrical contact surfaces. background In many applications, including automotive ones, there is a need to electrically connect various entities, such as the electrical components of an electric motor, to the electrical interface of another entity, such as the electronic control unit (ECU). In many cases, wires are used to connect the electrical components. Wires have the advantage of being flexible, allowing for movement between the components. In some applications, the components are mounted directly next to each other, so an electrical connection is formed directly between the respective contacts of the components. However, since movement resulting, for example, from component tolerances or thermal expansion, leads to a (large) axial gap, a certain degree of flexibility between the contacts could be advantageous. State of the art In the prior art, several connectors are known that make it possible to overcome the axial gap between two components, e.g., the contact between a motor and an ECU. Figures 5a and 5b show an electrical connector 60 comprising four elements: electrical contacts 62 on the first side, a spring 64, and another electrical contact 66 on the other side. The connector 60 also includes a housing 68. The spring 64 is arranged such that it overcomes an axial gap. For this purpose, the spring 64 is compressible and extendable. The first contact 62 has a plurality of flexible elements 62f configured to contact a contact terminal (not shown) to form an electrical connection, e.g., with a contact terminal of the ECU. The second contact 66 has a receiving element 66r configured to receive an external pin or external blade (not shown). Here, the receiving element 66r is configured to apply a force to the external pin or external blade, resulting in a secure connection. However, due to the arrangement of the spring 64, frictional movement can occur at the contact points, particularly when the spring 66 is compressed and extended. Therefore, an improved design is needed. Task The task is to provide a contact that overcomes the axial gap without frictional movement at the contact points. Solution Exemplary embodiments of the present invention provide an electrical connector for electrically connecting a first electrical element, such as a contact terminal, e.g., of an ECU, and a second electrical element. The electrical connector extends from a first side (e.g., the side of the first electrical element) to a second side support (e.g., the side of the second electrical element). The electrical connector has the following features: - a first conductor structure comprising a first spring section and a first contact wing; - a second contact structure comprising a second spring section and a second contact wing. The first and second spring sections are configured to provide length compensation between the first and second connector sides. The first and second contact wings are positioned opposite each other and configured to form a receiving element for an external pin or blade of the second electrical element. Exemplary embodiments of the present invention are based on the understanding that by using two conductor structures extending essentially along the direction from the first side to the second side, two functions can be ensured: length compensation between the first and second sides and the formation of an electrical contact with a sword, so that the sword is held by the two contact wings. Length compensation is achieved due to the elastic flexibility of a flexible section of the conductor structure. Since another section of the conductor structure is bent to form a receiving element, an external element such as a sword can be fixed without causing friction or movement at the contact point.In addition to length compensation, the flexible sections, which are referred to as spring sections, ensure, for example when they are compressed, that sufficient force is applied to the contact points, especially the contact point on the first side. According to one embodiment, the first conductor structure and the second conductor structure are formed in one piece. This is advantageous because it reduces complexity and thus manufacturing effort. Consequently, each conductor structure can, for example, have a transition between the respective (first / second) spring section and the respective (first / second) contact wing, which represents the second side of the connector. According to another embodiment, the first conductor structure and the second conductor structure are connected to form a common layer, e.g., on a first side. This advantageously allows the first conductor structure and the second conductor structure to be configured in such a way as to create a design in which all functions are integrated into a single part. The advantages also extend to the requirements for electrical performance, temperature, and oil. In exemplary embodiments, the first conductor structure and the second conductor structure extend from the common layer in one direction on the second side. In these embodiments, the first conductor structure and the second conductor structure are arranged essentially parallel to each other. For example, the symmetrical arrangement of the first conductor structure and the second conductor structure allows for optimal damping of axial movement without causing lateral deformation. This also makes it possible to avoid any friction at the contact point(s). For example, the first and second spring sections can have a meandering or S-shaped profile formed by a plurality of radii (a sequence of loops). The elastic behavior of the spring sections is achieved due to the radii formed by the S-elements. For instance, one and a half S-elements (three radii) can form each of the first and second spring sections. The geometry and the number of S-elements influence the elasticity rate and the total amount of axial movement. According to another embodiment, the thickness of the layer forming the first and second conductor structure, as well as the material itself, also influence the elasticity rate. These design variations advantageously allow the electrical connector to be designed for different applications. On the second side, a transition can be formed between the respective spring section and the contact wing. According to exemplary embodiments, the first and second contact wings are bent inwards. This advantageously allows the integration of the sword's mounting function and length compensation. In other words, this means that an inward extension of the first and second spring sections forms the first and second contact wings, and thus the mounting element. According to exemplary embodiments, the first and second contact wings are configured to apply a contact force to the pin or blade of the second element. This contact force is, for example, perpendicular to the axial direction along which the length compensation is performed. The contact force generates friction, advantageously holding the blade between the first and second wings (sandwich-like). According to further embodiments, the first and / or the second wing has a plurality of wing parts. These can be arranged side by side, so that a plurality of contact points are formed on each side between the sword (generally: external element) and the respective wing part. According to one embodiment, the second connector side can have a limiter section. This limiter section can extend, for example, from the transition point mentioned above to the side. For instance, the limiter section can be formed from a single sheet, i.e., in an integrated manner. According to embodiments, the limiter section is configured to contact a housing part, e.g., on the side, i.e., perpendicular to the axial direction, and to limit radial deformation of the first and second conductor structures, particularly when the spring elements are compressed and radially deformed due to length compensation. This advantageously allows the contact force on the pin or blade discussed above to be maintained regardless of axial movement. Furthermore, the limiter section can serve to provide a preload for the contact on the blade. As previously discussed, the first and second conductor structures can be formed from a single sheet, for example by bending, so that there is a common layer on the first side. This common layer can have a stiffening structure, such as corrugations. This stiffening structure advantageously ensures that the structure of the electrical connector is maintained regardless of the applied force. According to exemplary embodiments, the first connector side has a plurality of resilient contact elements extending from a common layer in one direction along the first connector side. The plurality of resilient elements advantageously enables electrical contact with the first electrical element, e.g., a contact terminal surface thereof. Due to the flexibility of the resilient contact elements, the contact force is maintained. According to exemplary embodiments, the spring-loaded contact elements are bent towards the first connector side by more than 135°, or by more than 150°, or by 180°. The radius provides (additional) flexibility to the spring-loaded contact elements. The spring-loaded elements make it possible to control the (minimal) contact force between the connector and the first electrical element. According to a further embodiment, the first connector face has a plurality of decoupled contacts, in particular decoupled contacts that can extend substantially perpendicular to the first connector face. These decoupled contacts are configured to limit the pressure (contact force) on the plurality of resilient contacts. It should be noted that the number and / or the respective bent angle depends on the stress profile and the force applied. If the force on the resilient contact elements is sufficiently large, they are compressed so that the decoupled contacts come into contact with the first electrical element, advantageously limiting the maximum force on the contact elements and the electrical contact surface of the first electrical element. According to another embodiment, it might be possible for the first connector side to have an additional spring element arranged between the spring-loaded contact elements and a common layer formed by the connection of the first conductor structure and the second conductor structure. According to exemplary embodiments, the connector, e.g., the connector comprising at a minimum the first conductor structure and the second conductor structure, is formed by a sheet metal part, in particular a metal sheet or a coated metal sheet. According to exemplary embodiments, it is also possible for the spring contact elements to be formed by the same sheet metal part. Depending on the cutting process, the limiter sections can also be formed by the same sheet metal part, according to further exemplary embodiments. This is advantageous because the number of components is significantly reduced, as the entire exemplary embodiment with some or all of the optional features can be formed by cutting and bending the sheet metal part. This offers significant advantages in terms of manufacturing. Another embodiment provides a method for manufacturing the electrical connector. The method comprises cutting or, for example, punching a metal sheet to form a first conductor structure and a second conductor structure (e.g., from the same metal sheet); and bending the first conductor structure and the second conductor structure to form a first spring section and a first contact wing from the first conductor structure and to form a second spring section and a second contact wing from the second conductor structure.

Detailed description of implementation examples Exemplary embodiments of the present invention are discussed below with reference to the figures, whereby identical reference numerals are provided for objects with identical or similar functions, so that their descriptions are interchangeable. Fig. 1 shows an electrical connector 10 for electrically connecting a first electrical element 2 and a second electrical element 4. The first electrical element 2 may have a contact surface 2a. The second electrical element 4 has a type of pin or blade 18, also referred to as an external pin or external blade to indicate that the pin or blade 18 is not part of the connector 10. The blade 18 may be a conductor. Due to thermal expansion and / or tolerances, the distance between the first electrical element 2 and the second electrical element 4 may vary. The electrical connector 10 is arranged between the first electrical element 2 and a second electrical element 4 to connect them electrically. In its minimal configuration, the connector 10 comprises a first conductor structure 14A and a second conductor structure 14B. The first conductor structure 14A has a first spring section 14SA, while the second conductor structure 14B has a second spring section 14SB. The first conductor structure also has a contact wing 15CWA, and the second conductor structure also has a second contact wing 15CWB. As can be seen, the first and second contact wings 15CWA and 15CWB are extensions of the respective spring elements 14SA and 14SB. Both spring elements 14SA and 14SB extend substantially parallel or in the same direction from a first side, i.e., from the first electrical element 2, to a second side, i.e., towards the direction of the second element 4. Preferably, the spring elements 14SA and 14SB are curved, e.g., as shown. For example, the spring elements 14SA and 14SB can be curved inwards with a radius. It should be noted that the spring elements 14SA and 14SB can interact due to their parallel arrangement. According to exemplary embodiments, the shape of the spring elements 14SA and 14SB can be different, e.g., such that they have a meandering shape, an S-shape, or a similar shape, such as a shape defined by a sequence of loops.Elements 14SA and 14SB are flexible and, based on this flexibility, configured to provide length compensation between the first connector side 2 and the second connector side 4. For example, compensation of ± 0.5 mm or ± 1 mm, or in the range up to 5 mm, could be possible. In other words, this means that spring elements 14SA and 14SB offer flexibility in accommodating different distances or tolerances between contact planes 2C and 4. This makes the design suitable for applications where physical movement or tolerance adjustments may be required. At the ends of elements 14SA and 14SB, a transition point 14TA and 14TB is arranged where the wing elements 15CWA and 15CWB are bent further inwards. For example, the wing elements 15CWA and 15CWB are bent in the direction of element 2 so that they are arranged opposite each other and configured to form a receiving element for the external blade 18. Due to the geometry, the contact wings 15CWA and 15CWB can be configured—according to exemplary embodiments—to apply a contact force to the blade 18. This contact force creates a coupling between the contact wings 15CWA and 15CWB and the blade 18. According to exemplary embodiments, this means that the structure includes integrated receiving elements 15CWA and 15CWB, which likely serve as an interface for the connection and ensure that the contact pressure is maintained regardless of the assembly force.The receiving elements can be part of the mechanism that decouples the contact pressure from the mounting force. The transition points 14TA and 14TB are located on a second side of the electrical connector 10. A contact area 12 is formed on the first side opposite the second side. Here, the connector 10 can be contacted with the contact surface 2C of the electrical element 2. The electrical component 2 can be the printed circuit board of an ECU, where 2C can be a contact surface of the printed circuit board 2. Optionally, the contact area can have 12 flexible elements, as discussed in relation to the following embodiments. According to one embodiment, the three sections 14SA, 12C, 14SB, together with the two contact wings 15CWA and 15CWB, can be formed in one piece. For example, the base can be a metal sheet bent at the transition point 14TA and 14TB to form the two contact wings 15CWA and 15CWB, and bent along the radii of the spring elements 14SA and 14SB to form them. The two conductor structures 14A and 14B can have a further transition to the contact area 12C. Having now discussed the basic structure and functionality of the one-piece formed electrical connector 10, optional features and variants are discussed with reference to Fig. 2, Fig. 3a, Fig. 3b, Fig. 3c, Fig. 3d and Fig. 3e. With reference to Fig. 2, a further embodiment is discussed. Here, some parts could be designed differently, but this basic function is comparable to the connector 10 of Fig. 1. Therefore, the same reference numerals are provided for the comparable elements so that their descriptions are mutually applicable and interchangeable. Fig. 2 shows the electrical connector 10, which has a first connector side 12 and a second connector side 16. Between the first connector side 12 and the second connector side 16 extend the conductor structures 14A and 14B, which are also referred to as the first conductor structure 14A and the second conductor structure 14B. Each of the conductor structures 14A and 14B has the spring sections 14SA and 14SB and a respective contact wing 15CWA and 15CWB. The contact wings 15CWA and 15CWB are designed as inwardly curved strip sections. Both elements 14SA and 14SB are arranged essentially parallel. According to this embodiment, the spring sections 14SA and 14SB have an S-shape, which here, for example, has one and a half S-curves. Viewed from a side perspective, see Fig. 3a, the meandering or S-shaped spring elements 14SA and 14SB can be described as mirror images of each other, so that together they form a butterfly shape. In other words, this means that the connector 10 consists of several curved, spring-like components, which probably serve to provide contact pressure both in the axial direction and perpendicular to the axial direction, namely towards the sword 18, as discussed above. The axial force is denoted by F12, and the contact force on the sword 18 is denoted by F15r in Fig. 3a. According to exemplary embodiments, the two spring elements 14A and 14B can be connected to each other on the first side to form a common layer 12CL. From this common layer 12CL, the spring elements 14A and 14B extend in one direction towards the second connector side 12. According to exemplary embodiments, the first connector side 12a has a plurality of contact elements 12CE arranged such that they extend in one direction along the first connector side, i.e., towards the element 2. These contact elements 12CE can be flexible and are therefore referred to as resilient contact elements 12CE. They can be attached to or extend from the common layer 12CL and can be bent by approximately 180° to form the contact point 12Cp for the first electrical element 2 (see Fig. 1). These resilient elements 12CE are flexible to provide or control the contact force for the contact termination surface 2. The resulting contact force is denoted by F12CE in Fig. 3a and Fig. 3bb. It should be noted that the number of spring contact elements 12C can vary. Six spring contact elements 12CE are shown here together with four decoupling elements 12DE. According to other embodiments, two, three, or four spring contact elements, or a completely different number, are also possible. According to further embodiments, additional decoupling elements 12dc can optionally extend from the common layer 12C in the first direction. These decoupling elements can, for example, extend substantially perpendicularly in the direction of the first side and are configured to limit spring movement of the resilient contact elements 12CE and thus the (maximum) contact force. These decoupling elements 12dc can be arranged to contact the first electrical element in an area adjacent to the contact terminal surface of the electrical element. In other words, the resilient contact elements 12CE advantageously enable a contact force F12 to be maintained on the first electrical element, while the decoupled elements 12dc allow the contact pressure to be limited and decoupled from the actual force, in particular the assembly force during the assembly phase.Consequently, the contact pressure on the ESU (electronic control unit) is decoupled from the actual mounting force. This means that the force applied during assembly does not directly affect the electrical contact pressure, which is advantageous for ensuring reliability and performance over time, even if mounting tolerances vary. For example, the force may be limited to approximately 30 or 34 newtons (generally in the range between 10 and 50 N), with the spring contact elements 12CE ensuring a minimum contact force of, for example, 10 or 15 newtons, generally in the range between 5 and 20 N. It should be noted that the force typically depends on the selected material and the thickness of the bent sheet. According to exemplary embodiments, the connector can have a cylindrical shape. For example, the connector can be guided through a housing 4H with a cylindrical block. This is shown in Fig. 3a, Fig. 3b and Fig. 3d. As mentioned above, the two wing elements 15CWA and 15CWB are bent and facing each other, forming a receiving element 15r for an external blade 18. The structure includes integrated receiving elements, which likely serve as interfaces for the connection and ensure that the contact pressure is maintained regardless of the assembly force. Due to the elastic bending, these elements are configured to apply a contact force f15r to the external blade. This contact force f15r, as shown in Fig. 3a, is independent of axial compensation and / or an assembly force. According to further embodiments, a plurality of contact wings 15CWA and 15CWB can be used on each side. In Fig. 2, three contact wings 15CWA and 15CWB are shown on each side. The plurality of contact wings 15CWA faces the plurality of contact wings 15CWB, so that the sword can be fixed by the force f15r, as shown in Fig. 3a, Fig. 3b or Fig. 3d. According to exemplary embodiments, the two conductor structures 14A and 14B can have a limiter 16L arranged in the region of the transition point 14TA and 14TB. The limiter can have a plurality, here four, circular segments that can be contacted with a housing 4H to support the contact force f15r. The contact between the limiter 16L and the housing 4H is shown in Figs. 3a, 3b, and 3d. Due to the support provided by the limiter 16L, the contact force is maintained even if the spring elements 14A and 14B are compressed in such a way that they could spread apart. Additionally, the limiter section 16L can serve to provide a preload for the contact on the blade 18. As can be seen in Fig. 4, the limiter 16L has a round shape, with its diameter adapted to the bore of the housing 4H. If the housing has a different shape, e.g., a square shape or another shape, the shape of the limiter 16L can also vary. It should be noted that the force F15r is perpendicular to the axial direction of the connector 10, while the forces F12 and F12CE act essentially parallel to the axial direction of the connector 10. Based on the structure discussed above, different states (compressed / uncompressed state) of the connector 10, as shown in Figs. 3a to 3d, are discussed. Fig. 3a shows the electrical connector 10 compressed between the first electrical element (see first connector side 12) and the second electrical element (see second connector side 16), while Fig. 3b shows the same connector 10 stretched or uncompressed. As can be seen, the "butterfly" shape of the spring-like components 14SA and 14SB can vary slightly due to the axial displacement without affecting any contact force F15r, F12, or F12CE. It should be noted that the force F15r, which relates to the force at the contact points between the blade 18 and the wing elements 15CWA and 15CWB, is comparable. The force F12CE is the force at the contact 12CP between element 2C and the contact element 12CE and results mainly from the compression of the elements 12CE.F12 is the axial force acting on the two spring elements 14A and 14B, which are designed to provide length compensation. This makes the design suitable for applications where physical movement or tolerance adjustments are required. As can be seen in relation to Fig. 3c, the contact force F12CE is limited because the decoupling elements 12DE are in contact with component 2, so that the spring contact elements 12CE are not bent further. Figures 3d and 3e depict the situation in which the axial force is further reduced. Here, contact 12CP is still maintained due to the torque of the spring contact elements 12CE. This is because the decoupling elements 12DE are no longer in contact with component 2. Consequently, only contact between 12CE and 2C is maintained. In other words, the spring contact elements 12CE ensure contact with element 2C. As mentioned above, the electrical contact 10 is manufactured from a single piece of stamped metal. This metal before bending is shown in Fig. 4. Fig. 4 shows the connector 10, which comprises the elements 12, 12DE, 12CE, 12CL, 14A, 14SA, 14B, 14SB, 15CWA, 15CWB, and 16L. The shape indicates that it was produced from a grid using a stamping process, which helps to reduce manufacturing complexity while ensuring precision. As can be seen, all these elements are arranged side by side before being bent into a 3D component. Preferably, the sheet metal is a metal sheet, such as steel, spring steel, or copper, so that conduction from one side to the other is possible. According to exemplary embodiments, it is possible for the sheet metal to be coated, e.g., with silver, to enhance the conductivity.The choice of material or, in particular, the coating may depend on the material pairing with the contacts 2C or the sword 18. According to the exemplary embodiments, the diameter of the connector is approximately 10 mm or 30 mm, generally between 5 mm and 15 mm, 5 mm and 20 mm, or 5 mm and 50 mm. The height can be approximately 10 mm or 14 mm, or generally in a range between 5 mm and 15 mm, 5 mm and 20 mm, or 5 mm and 50 mm. Naturally, the size depends on the application. As can be seen in Fig. 4, the spring sections 14SA and 14SB are formed by a strip of bent metal. The strip can have a continuous width or a varying width. Here, the width is increased in the middle to optimize the elastic properties. The shape indicates that it was produced from a grid using a stamping process, which helps to reduce manufacturing complexity while ensuring precision. All radii are marked by the hatching. According to a further embodiment, an additional spring, which may, for example, have a meandering shape, can be arranged. In this case, the section between the first conductor structure and the second conductor structure and the common layer 12CL can be arranged in a way that allows it to be folded into a meander to provide an additional spring force and, in particular, an additional displacement distance. According to exemplary embodiments, this type of connector could be used in automotive or industrial electronics where reliable connections are required despite large mechanical tolerances or movement. The design allows for compensation of varying distances between the contact planes, which is particularly useful in environments subject to vibration, thermal expansion, or other mechanical stresses. The overall design enables consistent electrical contact in applications where mechanical tolerances vary or are difficult to control. It should be noted that, according to exemplary embodiments, the electrical connector can be positioned between two elements, such as an ECU and a motor, with the bore of housing 4H being filled with a fluid, such as oil. According to one embodiment, the connector 10 is implemented as a stamped part that is clamped into the phase ring and connected to the blade 18 and the control unit 2. Another embodiment provides a method for manufacturing the connector 10. This method comprises the two main steps of punching the sheet metal and bending the section to achieve the design discussed above. As mentioned, the radii or bent sections are hatched in Fig. 4. It should be noted that a description of a feature discussed in connection with a device also constitutes a description of a corresponding process step, and vice versa. The above embodiments serve an illustrative purpose, the scope of protection being defined by the following claims.
