Description

Bus bar with elastic structure
Technical Field
The invention relates to a busbar, in particular for an electric vehicle. The busbar comprises at least one, in particular flat, connecting section and at least one electrical connection formed in the region of an end of the connecting section. The connecting section is designed to be elastic and has an arched region and at least one slit formed in the arched region.
Background
The bus bar has, for example, a connection for connecting to a further electrical component, which bus bar is, for example, a component of a power electronics system in the automotive field, in particular a bus bar is a component of an electric or hybrid vehicle. In the region of the joint, assembly tolerances can be compensated for by large screw holes in the joint, but the current carrying capacity in the connecting region is thereby reduced. The thermomechanical forces or vibration loads can be reduced in an uncontrolled manner in the region of the busbar, which can lead to damage at the contact points. The forces in the contact points, which are produced by differential thermal expansion, can permanently damage the contact points or the electrical components connected to the contact points, so that the transition resistance at the contact points increases.
DE 202010005554U 1 discloses a transition between two connecting devices for conductors in an insulating housing, wherein the connecting devices are connected to one another by a metallic bus bar.
DE 102015115464 a1 discloses a power distributor device for vehicle applications, which has a power distributor bar arranged in a housing and having a specially designed mounting section, which is separated from the rest of the bar by a specially formed slot.
Disclosure of Invention
According to the invention, for a busbar of the type mentioned at the outset, the arched region of the elastically formed connecting section is of spherical crown shape, in particular shell shape, half-shell shape or hemispherical shape. This advantageously allows the joint to be relieved elastically in rotational degrees of freedom that differ from one another. The connecting section can thus be designed as a tolerance compensation element. The connecting section can advantageously be designed to reduce mechanical loads in three different spatial directions, in particular forming an orthogonal system.
Preferably, the at least one slit is formed along the longitudinal extension of the connecting section which points toward the joint or is formed with a main directional component which points toward the joint. Preferably, the connecting section has a longitudinal extension which is greater than a width extension extending transversely thereto. It is further advantageous if the bus bar, in particular the connecting section, can be provided cost-effectively as a stamped plate.
In a preferred embodiment, the busbar has a different bending radius in the arched region, in particular in the extension of the connecting section toward the joint, than the transverse extension running transversely to the extension. The extension is preferably configured as the extension of the connecting line between the joints. In this way, the spring action can advantageously be formed with a soft spring constant during rotation about the longitudinal extension.
In an advantageous embodiment, the bending radius is configured to be smaller in the extension towards the joint than in the transverse extension. This advantageously results in a good spring action in the direction of torsion.
In a preferred embodiment, the connecting section has at least two or more slits, each of which is formed as a slit, in particular extending parallel to one another in the region of the arch. In this way, webs or webs running parallel to one another can advantageously be formed on the connecting section, as a result of which the mobility of the busbar is advantageously improved. Preferably, two webs or webs are formed adjacent to the gap.
In a further embodiment, the slots are each formed in a wave-like manner, in particular in a sinusoidal, trapezoidal or zigzag manner. In this way, good torsion spring properties can advantageously be formed on the connecting section.
In a preferred embodiment, the busbar is formed at least in the region of the connecting section from at least two arched plates stacked one above the other. In this way, a stack of arched leaf springs can advantageously be formed. The plate elements are preferably spaced apart from one another in the region of the connecting section.
In a preferred embodiment, a slot is formed in each plate of the stacked lamination stack forming the busbar. In this way, the movability of the lamination stack can advantageously be improved by the lamellae thus formed in each plate.
In a preferred embodiment, the webs formed between the two slits each have a width of between one and five millimeters. In this way, the bus bar can be advantageously designed as a connecting element which is part of an electronic circuit.
In a preferred embodiment, the plate thickness of each of the plates stacked in the lamination stack is between 0.05 and 0.3 mm. In this way, the lamination stack can advantageously be constructed with a high degree of flexibility.
In a preferred embodiment, the width extension of the sheet or web formed between the slots along the transverse extension running transversely to the slot extension decreases from the center of the busbar towards the edge. In this way, a good torsion spring action around the longitudinal axis can advantageously be created.
In a preferred embodiment, the stacked plates are connected to one another in the region of the joint in a material-locking manner, in particular welded. In this way, the lamination stack can advantageously form a bus bar, which is formed in particular in one piece.
In a preferred embodiment, the busbar is formed by a copper alloy, such as CuSn6, which includes copper as a main constituent and six weight percent tin. In another embodiment, the copper alloy is formed, for example, from a copper alloy comprising a dopant, which comprises chromium, silver, iron, titanium, silicon and a maximum proportion of copper. The proportions of the dopants are, for example, 0.5% by weight of chromium, 0.1% by weight of silver, 0.08% by weight of iron, 0.06% by weight of titanium and 0.03% by weight of silicon. Such as an alloy according to standard UNS 18080. As such, the copper alloy advantageously has good electrical conductivity and a large elastic modulus, so that the connection section can be provided with good spring force and small ohmic losses.
The invention also relates to an electric or hybrid vehicle having a busbar of the type described above. The bus bar is preferably an electrically conductive connecting element which connects the inverter of the vehicle at least indirectly to the electric machine of the vehicle.
The invention also relates to a converter or DC-DC converter, wherein the converter or DC-DC converter has at least one busbar. The bus bar connects, for example, a DC link capacitor to a semiconductor switch bridge, in particular a B6 bridge. Such as a component of a photovoltaic installation or a wind power installation. In this way, a large number of long electrical connecting lines can be coupled to one another with the busbar under low force. In this way, the forces in the contact points, which are generated by different thermal expansions, can advantageously be captured in the connecting section of the busbar in a resilient manner.

fig. 4 shows the connecting section shown in fig. 3 in a sectional view.
Detailed Description
Fig. 1 shows an exemplary embodiment for a busbar 1. The bus bar 1 has end sections 2 and 3 at opposite ends, wherein the end sections 2 and 3 form an electrical connection. The end sections 2 and 3 are connected to one another by means of a connecting section 5 and are each formed onto the connecting section. The connecting section 5 is formed resiliently and has an arched region for this purpose. The arched region is formed along the longitudinal extent 19 of the busbar 1 on a longitudinal section 4, which in this exemplary embodiment corresponds to the longitudinal dimension of the connecting section 5. The busbar 1 is thus formed in a curved arch shape on the connecting section 5.
On the connecting section 5, the busbar 1 has a plurality of slots which extend parallel to one another along a longitudinal extent 19. The slits thus separate the lamellae of the connecting portion 5 which are arranged adjacent to one another and are formed by the slits. The bus bar 1 is produced, for example, from a sheet metal part by punching and/or stamping and thus by deformation, for example cold deformation. Such as a copper plate.
The busbar 1 has lamellae 6, 7, 8, 9, 10 and 11 arranged adjacent to one another on the connecting section 5. The sheets 6 and 7 are separated from each other by a slit 12, the sheets 7 and 8 are separated from each other by a slit 13, the sheets 8 and 9 are separated from each other by a slit 14, the sheets 9 and 10 are separated from each other by a slit 15, and the sheets 10 and 11 are separated from each other by a slit 16. The slots 12, 13, 14, 15 and 16 are produced, for example, by means of blanking, sawing, milling or laser cutting. The connecting section 5 is thus designed as a resiliently movable structure in mutually different translational and/or rotational degrees of freedom, so that the joints 3 and 2 are mechanically decoupled from one another.
Fig. 2 shows the busbar 1 shown in fig. 1 in a sectional view along the section 17 shown in fig. 1, which is transverse to the longitudinal axis 19. The lamellae 6, 7, 8, 9, 10 and 11 together span the arch of the arch formed by the connecting section 5, wherein the arch is configured in this exemplary embodiment as a circular arc. The camber angle 18 associated with the camber is 90 degrees in this embodiment. The arcuate angle 18 can be between 45 degrees and 140 degrees in another embodiment.
Fig. 3 shows an embodiment for a busbar 20, which is formed by a laminated stack of three plates 21, 22 and 23 stacked one on top of the other. The sheets 21, 22 and 23 are produced by blanking and deforming, respectively. The plates 21, 22 and 23 are each connected to one another in a cohesive manner, for example by resistance welding, spot welding, laser welding or by soldering, in particular brazing, in the longitudinal section 25 along the longitudinal extent 41 of the busbar 20. In this way, an electrical connection 27 is formed on the longitudinal section 25, which can be connected to a further stamped grid or lead frame, for example by means of soldering, screwing, snap-in or riveting, or soldered to the line base in a soldering furnace by means of a reflow soldering technique by means of a Surface mounting technique, in particular an SMD technique (SMD). The fitting designed for screwing on has, for example, a through-hole through which a screw can be passed.
The terminal 27 forms an end section of the busbar 20, wherein a further electrical terminal 28 is formed along the longitudinal section 26 at the opposite end along the longitudinal extent 41. The joints 27 and 28 are each formed on a connecting section 29 which extends along the longitudinal section 24 along the longitudinal extent 41 and is designed in the shape of a bow. The dome is configured in this embodiment as a spherical crown.
The individual plates 21, 22 and 23 each have webs on the connecting section 29 of the busbar, which webs are each separated from one another by a gap. The lamellae of the single plate 23, i.e. lamellae 30, 31, 32, 33, 34, 36, 37, 38, 39 and 40, are exemplarily marked. The busbar 20 has a break 35 in the connecting section 29, which is formed in this exemplary embodiment by an opening or recess 35 extending along the longitudinal extent 41. The gap 35 is arranged between the lamellae 34 and 36 and has a greater width than the gap formed between the individual lamellae. The gaps between the lamellae each have a width which is smaller than the width of the lamellae that are each separated from one another by a gap.
The thickness of the individual plates is for example 0.1 mm. The bus bar can be formed by at least two or, as shown in fig. 3, three individual plates stacked one on top of the other. The bus bar can be formed, in contrast to the illustration in fig. 3, from five, five or more, ten or more, fifteen or more or twenty individual plates, which are each stacked one above the other. The sheet width of the sheet is for example between half and three millimetres, preferably one millimetre. The slits can be cut into individual sheets, for example, before or after the formation of the arch. In particular, in a flat projection of the connecting section, the slits are each formed straight and run parallel to one another in this exemplary embodiment. In contrast to the illustration in fig. 3, the slots are formed in a wavy, in particular sinusoidal, trapezoidal, in particular rectangular or triangular manner, in particular in a flat projection.
Fig. 4 shows the busbar 20 shown in fig. 3 in a sectional view, wherein a section transverse to the longitudinal axis 41 is shown in the arched region 29. The individual plates 21, 22 and 23 in this exemplary embodiment each have the same curvature, in particular in the region of the curvature, which determines the curvature. The arcuate arcs spread by means of the lamellae 30, 31, 32, 33, 34, 36, 37, 38, 39 and 40 have in this embodiment an arcuate angle of 45 degrees. By means of the lamination stack formed by the intermediate recess 35, which in this exemplary embodiment comprises five lamellae or webs arranged relative to one another, a soft torsion spring can be formed, so that the respectively flat connections 27 and 28 can spring relative to one another in a manner rotating about an axis formed along the longitudinal extent 41 and thus form a torsion spring.
