Definitions

  • the invention relates to a system for transmitting electrical current from a first component to a second component, the first component being in electrical contact with the second component.
  • Such contact systems are used, for example, when connecting battery modules.
  • the contact systems must be designed in such a way that they can transmit currents with a current strength of up to 500 A without a large voltage drop.
  • the total resistance of the contact system must therefore be as low as possible.
  • the two components usually have a distance that must be bridged by a contact element.
  • the contact element In order for the contact resistance between the contact element and a component to be as small as possible, the contact element must be pressed against the surface of the component with a minimum force.
  • Contact elements therefore often have a spring mechanism that ensures the required contact force between the contact element and the component. The contact force must be maintained throughout the entire life of the system to avoid an increase in contact resistance.
  • the contact element must be able to compensate for manufacturing tolerances of the components and thermal expansion and vibrations.
  • the electrical provided by the contact system should The connection between the components can be detached again when the components are separated from each other. In some cases, however, it is desirable for the electrical connection to be maintained when the components change their position relative to one another, especially if the distance between the components increases due to undesirable external influences. In these cases, the connection between the components should be almost inseparable, i.e. only resolvable with considerable effort.
  • JP H05 69866 U discloses a connector in which lamellas are machined out of a strip-shaped connection element.
  • the slats are machined from the entire thickness of the strip-shaped connecting element.
  • the publication EP 856913 A1 discloses a high-current contact element made from a sheet metal stamping.
  • a contact area has a plurality of contact spring tongues that are punched out of the sheet metal stamped part.
  • the contact spring tongues therefore have the same thickness as the stamped sheet metal part.
  • the publication DE 10 2007 030 134 B3 discloses a conductor connector with one or more spring washers. Each spring ring is designed with several spring lamellas pointing inwards. The material of the spring lamellas is as thick as the material of the spring ring.
  • the publication WO 2016/187089 A1 discloses an electrically conductive material with a base body made of a copper material and a coating applied thereto. Channels running parallel to one another are introduced into the coating, so that lamellar elevations are formed between adjacent channels.
  • the publication DE 10 2013 015 088 A1 discloses an electrical contact element for a mechanically switchable electrical switching contact.
  • the Contact element is formed from a wire section-shaped fiber composite material, in which many thin, electrically conductive fibers are embedded in an electrically conductive matrix material, which are arranged essentially parallel in the matrix material and in the longitudinal direction of the wire section.
  • the electrical contact is established by a mechanical contact between the ends of the many fibers on the contact surface of the contact element, which is arranged on the end face of the wire section, and a flat counterpart or counter contact.
  • a device for producing detachable connections for electrical lines is known.
  • a sheet metal is placed between the lines to be connected, which is made of elastic material and is provided with a large number of elevations.
  • the elevations can be in the form of humps.
  • an electrical contact device with a pressure-loaded contact intermediate layer is disclosed.
  • the intermediate contact layer has projecting parts and can have a corrugated or curved shape.
  • the contact intermediate layer is made of spring-hard material.
  • the slat body includes a plurality of curved slats that are separated from each other by slots.
  • the slats work according to the leaf spring principle.
  • the disadvantage of such spring elements which are installed as an additional part between two components, is that the current must first be transferred from a first component to the spring element and then from the spring element to a second component.
  • the contact system therefore has at least two Contact points with significant contact resistance.
  • the invention is based on the object of specifying an improved system for contacting current-carrying components, i.e. for transmitting electrical current from a first to a second component.
  • the system should be suitable for current strengths between 10 A and 500 A, have a low contact resistance and be simple and inexpensive to produce.
  • the invention includes an arrangement of components for transmitting electrical current from a current-supplying component to a current-dissipating component.
  • the arrangement comprises a first component, which is the component supplying current to the arrangement or the component dissipating current from the arrangement.
  • the first component comprises a first metallic material and has on at least one surface at least one resilient lamella made of the first metallic material, machined, in particular formed, from the first metallic material on this surface.
  • the lamella is only made from a layer of the first metallic material that covers the surface.
  • the at least one lamella is machined from the first metallic material on the surface of the first component in such a way that it is monolithically connected to the first component in a connection area and extends from this connection area to a free end.
  • the lamella If the lamella is deflected from its rest position in the direction perpendicular to the surface of the first component, it exerts a spring force directed away from the surface of the component.
  • This spring force includes a component perpendicular to the surface of the first Component is directed, i.e. a normal spring force.
  • the arrangement comprises a second component which is in immediate, i.e. in direct contact with the at least one lamella of the first component stands.
  • the first component not only has the function of connecting the arrangement to other components of a circuit that do not belong to the arrangement, but at the same time it serves to establish electrical contact with the second component by means of at least one resilient lamella.
  • the at least one lamella of the first component is placed in relation to the surface of the first component with regard to its position or orientation, then the surface of the first component is understood to be the outer surface of the first component, which would result if the at least one lamella would be removed.
  • a lamella can be understood as a band-, strip- or plate-shaped material projection with a thickness of D, a width of B and a length of L.
  • the length L of the lamella is measured along the connection area in which it is monolithically connected to the first component.
  • the width B of the slat is measured from the connection area to the free end of the slat.
  • the thickness D is measured perpendicular to the surface of the lamella, i.e. perpendicular to the length and width.
  • the thickness D of the lamella can be 0.05 to 0.6 mm, preferably 0.1 to 0.3 mm.
  • the lamella protrudes from the surface of the first component, so it rises above the surface of the first component.
  • the height of the slat can be defined as the distance between a point at which the slat is connected to the first component and its free end, this distance being measured perpendicular to the surface of the first component.
  • the height of the lamella is 0.1 to 5 mm, preferably 0.2 to 2.5 mm.
  • the invention therefore relates to a system for the direct transmission of electrical current from a first component, which the system current-supplying component or the component that dissipates current from the system, to a second component by at least one resilient contact element, which is machined out of the surface of the first component in the form of a lamella.
  • the resilient contact element is monolithically connected to the first component. It is therefore an integral part of the first component. Therefore there is no electrical contact resistance between the first component and the lamella. If the first component is brought into contact with the second component on the surface which has at least one lamella, the resilient lamella is deflected from its rest position towards the first component. In response, it exerts a normal spring force on the second component.
  • the size of the spring normal force can be adjusted by the geometry of the lamella, its angle of inclination to the surface of the first component and the choice of its material.
  • Metallic materials with a large modulus of elasticity are particularly suitable as the material for the lamella.
  • the particular advantage of this arrangement of components is that the integration of the lamellar, resilient contact element into the first component avoids a contact resistance between this component and the contact element and thus significantly reduces the overall electrical resistance of the arrangement. Furthermore, it is no longer necessary to insert a separate contact element between the first and the second component, for example a lamella strip. The number of necessary parts is thus reduced, which reduces effort and costs.
  • the first component already includes the contact element for contacting the second component. The entire arrangement becomes easier to assemble and more reliable in its function, since a separate contact element no longer has to be inserted between the current-carrying components and therefore cannot be accidentally forgotten or fallen out.
  • the arrangement is characterized by a compact design and a small space requirement.
  • At least one of the two components can have a metallic coating in the area of the contact point to the other component, which can include, for example, silver, gold, tin and/or nickel.
  • a metallic coating reduces the contact resistance between the components. Frictional forces and wear are also minimized.
  • the coating prevents corrosion on the surface of the component and can act as a diffusion barrier for the metallic base material of the component.
  • the first component can be a busbar.
  • a busbar is a rigid, preferably one-piece component made of an electrically conductive material, in particular metal, which is used for the transmission and distribution of electrical currents.
  • a busbar can, for example, be a straight flat profile, but it can also be a curved or angled flat profile. The profile of the busbar can also have other shapes, for example U-shape or L-shape, or it can be round.
  • a busbar has at least two contact areas, namely at least one for the power supply and at least one for the power removal. If a busbar is used as the first component in the arrangement according to the invention, then it has at least one resilient lamella as described above in at least one of its contact areas.
  • This slat is used to establish contact with a second component, which can also be a busbar.
  • the other contact area of the busbar can have any means for contacting another electrical component that is not part of the arrangement, for example clamping devices, recesses or bores, which can optionally have an internal thread.
  • the busbar can have several contact areas, each of which has at least one resilient lamella.
  • Such a busbar can be used to distribute currents, for example in a power storage device to distribute partial currents to individual storage modules.
  • the first component and the second component can be located in the current path of the arrangement.
  • the arrangement therefore does not include any further components in the current path: the first component is the component that supplies current to the arrangement or the component that dissipates current from the arrangement, while the second component is the current-dissipating or current-supplying component that is complementary to the first component with regard to current flow.
  • the arrangement only consists of the first and the second component.
  • the current path within the arrangement only consists of the first component and the second component.
  • the entire arrangement includes further components outside the current path, for example devices for positioning and mounting the first and second components.
  • the first or second component can be connected outside the arrangement to other electrical or electronic components, for example a resistor, a switch, a relay or a contactor.
  • the at least one lamella can be machined out of the first metallic material of the first component by means of a cutting process, in particular a cutting, chiseling, peeling, plowing or furrowing process, and by means of a bending process.
  • the lamella is formed from a layer of material which was worked out from the original surface of the first component by a suitable separation process in such a way that the layer of material is not completely separated from the surface, but rather monolithically in a connection area with the first component remains connected.
  • This material layer is lifted from the surface of the first component by a bending process in which the material layer is bent about an imaginary axis that extends along the connection area.
  • Cutting and bending processes can also be carried out in one step.
  • the lamella is therefore formed from the material on the surface of the first component and forms a material projection.
  • the metallic coating of the component described above can be applied in the area of the contact surface on the surface of the first component before the at least one lamella is machined out of the material of the first component.
  • the first metallic material of the first component can have a greater hardness in the connection area than outside the connection area.
  • the connection area can also be referred to as the base of the slat.
  • the at least one slat can be at an angle ⁇ of less than 80° in the rest position
  • Surface of the first component extends inclined.
  • the angle of inclination ⁇ is measured at the attachment point of the slat to the surface of the first component, i.e. in the connection area. Due to the arrangement of the lamella inclined to the surface of the component, the spring effect of the lamella can be achieved well.
  • the angle ⁇ at which the lamella extends in the rest position to the surface of the first component can be 40° to 70°. If the angle ⁇ is less than 40°, then the maximum deflection of the slat from its rest position is too small to generate a sufficiently large spring force. If the angle ⁇ is greater than 70°, then the component of the spring force perpendicular to the surface of the first component is relatively small, so that only a small normal spring force acts with small deflections of the lamella.
  • the at least one lamella can have a convex contour on its side facing away from the surface of the first component between the connection region and the free end of the lamella.
  • the lamella can have a convex curvature or a bend, which results in a convex outer contour of the lamella.
  • the angle that the tangent to the lamella forms with the surface of the first component changes in such a way that this angle becomes smaller as the distance from the lamella base increases.
  • the tangent angle in the area between the bend and the free end of the slat is smaller than in the area between the slat base and the bend.
  • the convex contour of the lamella increases the area with which the lamella can be in contact with the second component. The advantage of this embodiment is therefore a high spring force of the lamella with a simultaneously large contact area with the second component.
  • the at least one lamella can be divided into several segments, in particular divided transversely, starting from its free end.
  • the segments formed in this way are arranged adjacent to the lamella in the longitudinal direction.
  • the individual segments can be deflected to different extents from their respective rest position when they come into contact with the surface of the second component. By dividing the slat into adjacent segments, unevenness in the surface of the second component can be better compensated for than with an undivided slat.
  • the first component can consist at least partially of a metallic composite material, which comprises the first metallic material and a second metallic material, the second metallic material having a higher electrical conductivity than the first metallic material.
  • a metallic composite material which comprises the first metallic material and a second metallic material, the second metallic material having a higher electrical conductivity than the first metallic material.
  • the first metallic material which forms the outer layer of the first component, has good strength and spring properties and is therefore optimized for the function of the resilient slat.
  • the majority of the volume of the first component consists of the second metallic material. Due to its high electrical conductivity, this contributes to a low electrical resistance of the arrangement.
  • the first metallic material can in particular be a special copper alloy, while the second metallic material can in particular be high-purity copper or aluminum.
  • the metallic composite material is characterized in that the first and second materials are connected to one another in such a way that when current flows There is no significant electrical resistance at the interface across the interface between these two materials.
  • the first and second metallic materials can be cohesively connected to one another. This can be done, for example, through a plating process.
  • a coating comprising, for example, silver, gold, tin and/or nickel can be provided.
  • the first component can have an electrically insulating layer which is at least partially removed on the side of the lamella facing away from the surface of the first component.
  • an electrically insulating layer which is at least partially removed on the side of the lamella facing away from the surface of the first component.
  • the first component is electrically insulated over a large part of its surface and only those areas of the surface of the first component that are in contact with the second component are exposed. The safety of the entire arrangement is thereby improved.
