Definitions

  • the subject matter relates to a cable connector for motor vehicles and a method for producing a cable connector.
  • Cable connectors are also used to enable connections between a component such as power electronics, a battery, a motor, etc. and cables, as well as connections between a first cable and a second cable.
  • So-called connectors are widespread.
  • Well-known connectors in the automotive sector are mostly based on spring contacts.
  • a first and a second current-carrying base body usually made of metal, are connected/clamped with a spring arranged between them.
  • the restoring force of the spring enables the spring element to make permanent mechanical and electrical contact with the two base bodies.
  • These often very thin springs are designed in such a way that they have many point-shaped projections at least on a contact surface that lies against a base body, where the mechanical and electrical connection is made.
  • the electrical current flows between the spring and the base body at the contact points. Due to the limited area of such a relief surface, the contact resistance increases and Joule heating of the transition occurs.
  • the cables in today's vehicles are also increasingly used to conduct heat, not least because of the good thermal conductivity of their electrical conductor materials such as copper and aluminum. Cables are therefore often an essential part of heat management in vehicles.
  • a coupling between two cables or between cables and electrical components as well as between electrical components among themselves, e.g. between battery cell connectors or between battery module connectors among themselves or with a battery cell, a so-called flying coupling therefore has the task of conducting heat as well as conducting current.
  • connectors are not well suited to this because such transitions in the cable harness often generate additional unwanted heat through Joule losses.
  • heat transfer is hindered by the often thin spring components. Worse still, the low heat capacity of the thin springs due to their design can lead to rapid heating, which in the worst case can cause cable fires.
  • Screw connectors are far better suited to heat transfer.
  • comparatively large surfaces of two base bodies are pressed together with a force generated by a thread.
  • the large-area contact reduces the ohmic resistance and increases the thermal conductivity.
  • Screw connectors also usually have a large thermal mass compared to plug connectors. They therefore heat up more slowly than thin springs when exposed to high instantaneous currents. In this way, they ensure a low risk of overheating with the sluggish thermal behavior of the connection.
  • Such a large thermal mass and high thermal conductivity is particularly necessary in the power train of electric vehicles, where high currents can occur during braking (via recuperation), acceleration or high-current charging.
  • screwing is a more complex assembly step than plugging in, which takes longer and is more prone to errors.
  • This is particularly problematic in view of the increasing automation of production in the field of electromobility.
  • the increased time required to assemble screw connections makes them unattractive for automated production.
  • screw connectors can cause problems due to defective threads or similar, which is why some screw connectors already use contact parts with two screw elements next to each other in order to reduce the susceptibility to errors/error rates. This leads to further assembly work.
  • the publication US$5,174,777 refers to an electrical connector system.
  • the publication EN 10 2011 018 353 A1 relates to a connection of an electrical cable consisting of several wires or strands with a connector.
  • the object was designed to combine the advantages of a screw connection with those of a plug connection. To do this, large surfaces are to be pressed together with high normal forces in order to generate good electrical and thermal conductivity. Furthermore, the connector should have a large heat capacity in order to be able to absorb a lot of heat energy and not heat up quickly. Another focus is on assembly, which should be quick, reproducible and as easy to automate as possible.
  • the connector in question comprises a first metal part and a second metal part.
  • the metal parts can consist in particular of copper or a copper alloy and/or aluminum or an aluminum alloy.
  • high-strength aluminum alloys such as EN AW 6082 can be used.
  • Other materials such as other metals or alloys thereof, such as steel, silver, gold, lead, etc. can also be used, or other conductors such as polymers, semiconductors, or similar.
  • Combinations of non-conductors and conductors can also be used, in which conductors are arranged at least on contact surfaces described later and the non-conductors perform purely mechanical functions.
  • Combinations of different, better and worse conductive materials, such as different metals, for example copper and steel can also be combined. In this way, good conductivity on the one hand and high mechanical stability on the other can be achieved at reduced costs compared to a pure-type production.
  • the two metal parts can be made of the same material, in particular the same metal material. This has the advantage that contact corrosion caused by different redox potentials of different metals is excluded. Another advantage is that there are no different thermal expansion coefficients. This means that the two metal parts expand to the same extent when heated and thermal stresses are avoided.
  • both metal parts can be made from different materials and/or material combinations, in particular from two different metal materials.
  • a first metal part can be made from copper or a copper alloy and a second metal part from aluminum or an aluminum alloy.
  • aluminum cables for example solid flat conductors, and copper conductors, for example flexible stranded conductors, can each be connected to a metal part of the cable connector in a single type. In this way, contact corrosion between the cable and the connector is reduced or prevented.
  • At least one of the metal parts can be made of solid material. This is advantageous for the heat capacity of the component. It is also possible for at least one of the metal parts to comprise segments of flat parts. In this way, high stability can be achieved with low weight and low material usage. On the other hand, the increased surface can promote heat radiation and thus enable a higher maximum loss of the cable connector.
  • the size of the metal parts can be adapted to the cable thickness and/or current strength and thus to the expected heat generation and power loss. A larger size leads to a larger surface area over which heat can be radiated and transported away by convection. In addition, a larger volume leads to a higher heat capacity.
  • Connection terminals for conductors can be provided on one or both metal parts. These can be round, flat or otherwise shaped connection lugs.
  • the connection lugs can be designed for soldering or welding cables, e.g. friction welding, ultrasonic welding, resistance welding, laser welding, etc.
  • the connection lugs can be roughened, coated or otherwise surface-treated.
  • One or more holes can also be provided in the connection lugs.
  • the connection terminals can also be shaped as sleeves and/or cable lugs. They can be suitable for contacting and/or receiving flat conductors, round conductors, solid conductors and/or stranded wires.
  • the connection terminals are preferably made of the same material as the metal part to which they are attached. They can also be made of a different material.
  • a surface is a connected area on a three-dimensional body that can be divided into several segments.
  • a surface does not have to be flat, but can be composed of segments with different spatial orientations.
  • the orientation of a surface segment is characterized by its surface normal.
  • a surface normal is a vector that is exactly perpendicular to the corresponding surface segment.
  • surface normals of a surface segment of a body are directed away from the body so that the vector lies outside the body.
  • the length of the surface normal vector is irrelevant and is defined as normalized to a value, for example the value 1 of a certain chosen unit of length.
  • Two vectors are described below as being opposite to each other if their scalar product is less than zero. It is possible but not necessary that the two vectors are exactly antiparallel to each other. If the two vectors are perpendicular to each other, their scalar product is exactly zero.
  • the two metal parts rest against each other in certain areas.
  • a locking element is provided that moves the two metal parts apart.
  • the locking element moves each metal part in a respective locking direction.
  • the respective locking direction can be represented by a vector.
  • the locking directions of both metal parts are opposite to each other (see above, scalar product less than zero) and can in particular be essentially antiparallel to each other.
  • the locking element is formed as a locking surface on each of the two metal parts, which are directed opposite one another and are spaced apart from one another by a gap.
  • the locking part can be shaped as a cuboid, cylinder or otherwise, in particular the locking part can be tapered along a spatial axis.
  • the locking part can thus be shaped as a wedge.
  • the locking part is preferably inserted into the gap in an insertion direction that is different from the locking directions of both metal parts.
  • the insertion direction can be aligned essentially perpendicular to the locking direction of at least one of the two metal parts. To ensure a better hold of the locking part, it can be roughened, for example by means of knobs, grooves, a corrugation, a rough coating, etc.
  • At least one of the locking surfaces can also be correspondingly It is also possible for the locking element and/or at least one of the locking surfaces to be coated, for example with non-conductors such as silicone, rubber, plastic, which can deform elastically in particular and thus absorb mechanical stresses.
  • the locking element and/or at least one of the locking surfaces can also be coated with a conductive coating such as nickel, tin, etc., which can be softer than the other material of the locking part.
  • the locking part can be made at least partially from a similar or the same material as one or both of the metal parts. This choice of material avoids different thermal expansion coefficients and prevents contact corrosion. It is also possible for the locking part to be made from a different material than at least one of the metal parts, which can be either conductive or non-conductive.
  • the locking part can be made from a solid material. It can be made from a material that is not very compressible, such as solid copper or aluminum. It is also possible for the locking part to be made from an elastic material such as plastic, rubber, silicone, etc., or from material combinations such as rubberized glass or ceramic.
  • a locking part made from a solid material can fit exactly into the gap between the two locking surfaces, at least in sections, the width of which is predetermined by the other design of the connector as described below.
  • the locking part is not formed from a solid material, but has an elastic structure with spring characteristics.
  • it can comprise metal brackets.
  • the elastic elements for example brackets, can absorb mechanical stresses as deformation and can be flexibly inserted into the gap between the locking surfaces. No further material has to be arranged between the elastic elements.
  • the locking part comprises other components in addition to the elastic elements, such as a supporting, electrically conductive or non-conductive filling, which can be solid or elastic, etc.
  • the locking part can be formed as a separate element, completely separable from the two metal parts. It can also be attached in a guided manner to one of the two metal parts.
  • a rail can support the locking part so that it can move in essentially one direction. It is also possible to arrange the locking part so that it can rotate on one of the metal parts and screw it in to lock it. Since the contact with a screwed-in locking part can be small compared to a pushed-in locking part, it is particularly advisable to roughen the surface, for example by grooves.
  • the advantage of a guided locking part is that it cannot be lost if the connection is opened again. It can also be advantageous during assembly if no separate locking parts have to be kept in stock.
  • Each of the two metal parts rest against one another in certain areas. Contact surfaces are initially provided for this purpose.
  • Each of the two metal parts has a front contact surface which lies behind the locking element in the locking direction of the metal.
  • Each of the two metal parts also has a second, rear contact surface which lies in front of the locking element in the locking direction.
  • the locking element or the components of the locking element which are arranged on the respective metal part therefore lie between the two contact surfaces, the rear and the front, of the metal part.

  • the front contact surface is spaced from the locking element with the respective locking direction of the metal part.

  • At least partially is to be understood as meaning that at least part of the surface has a corresponding orientation. Since the surface does not have to consist of a single flat segment, it is conceivable that some areas of the abutting surfaces are not directed in the opposite direction to the locking direction of the other metal part, but others are. In particular, the areas of the abutting surface should be directed in the opposite direction to the locking direction of the other metal part, where the other metal part actually rests in the joined and/or locked state.

  • Fig.3 shows various possible alignments of the contact surfaces 24, 46, 26, 44 and abutting surfaces 28, 42, 22, 48 of the two metal parts 20, 40.
  • a top view of the cable connector 1 in question is shown.
  • the contact and abutting surfaces 24, 46, 26, 44 can essentially run as flat surfaces with a single alignment perpendicular to the plane of the drawing. They can also be curved, twisted or otherwise deformed. For the following considerations, at least one segment of each surface should be aligned essentially perpendicular to the plane of the drawing, so that the seam lines of the Fig.3 the area-wise alignment of the surfaces can be seen.
  • the locking directions 50, 52 of the two metal parts 20, 40 are shown in the Fig. 3 a.c. shown embodiments parallel to the contact surfaces 24, 26, 44, 46, which are aligned parallel to each other in the joined state.
  • FIG.3 For a more detailed explanation of the surface orientations, see Fig.3 , in which the surface normals 23 (vertical to rear abutment surface 22), 25 (vertical to rear contact surface 24), 27 (vertical to front contact surface 26), 29 (vertical to front abutment surface 28) for the first metal part 20 are shown.
  • Fig. 3d a design is shown in which the contact surfaces 24, 26, 44, 46 are curved in plan view. They can also be curved so much that their area-specific surface normals are no longer directed opposite to the surface normals of the associated abutting surfaces 22, 28, 42, 48. It is sufficient if the surface normals of the contact surfaces 24, 26, 44, 46 are directed opposite to the surface normals of the associated abutting surfaces 22, 28, 42, 48 in some areas.
  • the abutting surfaces 22, 28, 42, 48 are generally further away from the locking element 60 than the respective associated contact surfaces 24, 26, 44, 46.
  • the abutting surfaces 22, 28, 42, 48 can also, as in Fig. 3 e shown, closer to the locking element 60 than at least areas of the associated contact surfaces 24, 26, 44, 46.
  • Contact and abutment surfaces 24, 26, 44, 46, 22, 28, 42, 48 generally do not have to be formed from a single flat segment but can also comprise segments of different orientations.
  • An example design with such surfaces is shown in Fig. 3 f shown.
  • the abutting surfaces 22, 48, 26 and 42 were first separated into sub-areas (22a, 22b, 22c, as well as 48a, 48b, 48c and 28a, 28b, 42a, 42b), each of which has an orientation according to the invention.
  • the horizontal abutting surface areas in the figure have a different orientation.
  • the abutting surfaces comprise these horizontal sub-areas and the sub-areas aligned according to the invention (22a, 22b, 22c, as well as 48a, 48b, 48c and 28a, 28b, 42a, 42b).
  • the abutting surface 28 was provided with highlights.
  • the elevations 28a, 28b themselves can also be regarded as the abutting surface 28.
  • Their surface orientation is irrelevant for the function of the invention. However, at least small segments of the result will be aligned against both the locking direction 52 of the second metal part 40 and the surface normal of the associated contact surface 26.
  • the alignment of the abutment surface 42 already causes the first metal part 20 is pressed with its contact surface 26 against the contact surface 44 of the second metal part 40. It is clear here that the regionally objective alignment of the two contacting abutting surfaces (22, 48) and (28, 42) is sufficient to press the associated contact surfaces (24, 46) and (26, 44) against each other by means of the locking element 60.
  • Fig. 3 g shows another related embodiment in which the abutting surfaces 22, 48 and 28, 42 are divided into three sub-areas, each with a substantially constant alignment.
  • the horizontally aligned sub-areas (surface normal substantially vertical) are aligned according to the invention.
  • the vertically aligned sub-areas (surface normal substantially horizontal) alone would not achieve the desired locking.
  • the abutting surface can refer to either just the horizontally aligned sub-area or the combined surface made up of two vertical and one horizontally aligned sub-area.
  • Fig.4 shows two different exemplary designs of the metal parts 20, 40.
  • Both metal parts 20, 40 are formed from several flat segments.
  • the contact surfaces 24, 26, 44, 46 and abutment surfaces 22, 28, 42, 48 are each formed from flat segments that are essentially parallel to the respective contact or abutment surface.
  • vertical flat elements are provided. These are optional.
  • One advantage of this design is the lower material expenditure, another is the increased surface area to the environment, through which heat can be radiated and released in other ways, such as via convection.
  • FIG. 4b Another design, shown in the Fig. 4b , resembles a cylinder.
  • a cylindrical shape makes it easier to integrate the cable connector 1 into cable harnesses. This is because the connector can be made to approximately match the cable diameter, particularly for cables with a round diameter. In this way, thickenings along the cable harness in the area of the Cable connector 1 is avoided. Thanks to the lack of edges, damage to neighboring components, especially cables, is also less likely.
  • Fig.5 carries out the embodiment Fig. 3g even further.
  • One of the abutting surfaces of two abutting surfaces in contact with each other can be shaped as one or more point-like, linear or otherwise shaped elevations instead of as a surface.
  • the elevation can be flattened and have a front surface that is aligned essentially parallel to the surface against it when locked. It can also be rounded. A rounded design is in Fig. 5a shown. If the elevation is rounded, only a very small surface segment of the abutment surface 42 is aligned against the locking direction 50 of the first metal part 20 and the surface normal of the contact surface 44.
  • the alignment of the other abutment surface is sufficient to guide the two contact surfaces associated with the respective abutment surfaces towards each other based on the force emanating from the locking element 60.
  • the elevations of one abutment surface can, for example, essentially form a line as in Fig. 5b
  • the survey is not, as in Fig. 5a , rounded, but has a flattened front surface.
  • a rounded shape is just as possible.
  • Several such linear elevations parallel to each other or inclined to each other are also possible.
  • point elevations as in Fig. 5c conceivable.
  • individual or multiple elevations distributed in an orderly or random manner on the abutting surface are conceivable.
  • At least one abutting surface can be heavily roughened, resulting in an irregularly shaped surface structure with elevations and depressions which, when the cable connector 1 in question is locked, partially come into contact with the opposite abutting surface of the other metal part and/or are pressed in and/or penetrate into the opposite abutting surface.
  • Fig.6 shows possible embodiments of locking elements 60, in addition to the Fig. 1a disclosed wedge 66 with locking surfaces 62, 64.
  • the guide 67 can have the property that the locking part 66 can only move in one direction. Furthermore, the guide 67 can connect the locking part 66 to at least one of the metal parts 20, 40 in a captive manner. This has the advantage that for the assembly of the cable connector 1 in question only two separate elements have to be handled, namely the two metal parts 20, 40. No locking part 66 has to be kept in stock in a processing machine, etc. Even if the cable connector 1 is opened, the locking part 66 is not in danger of being lost.
  • a wedge is disclosed as a locking part 66 which is movable along a guide 67.
  • This guide 67 can comprise a rail or other substantially linear elevation in the locking surface 62 which is surrounded by a groove or other substantially linear recess in the locking part 66.
  • the guide can be arranged as a recess in the locking surface 62 of the metal part 20 (or the locking surface 64 of the metal part 40) and the elevation on the locking part 66.
  • FIG. 6b Another example of a locking element 60 with guide 67 is shown in Fig. 6b shown.
  • the locking part 66 can be rotated around a guide 67 formed as a rotary bearing.
  • a rounding of the locking part 66 shown is advantageous in order to completely insert the locking part 66 in the gap into the lower part of Fig. 6b to be able to move to the end position shown.
  • Alternative locking elements 60 are in Fig. 6 df shown.
  • the locking element 60 comprises a screw guided in a thread of a first metal part 20, which can be rotated against the locking surface 64 of the second metal part 40.
  • the locking part 66 is the screw in this case.
  • Fig. 6e shows a spring element as a locking part 66, which is fixedly or movably attached to the locking surface 62 of the first metal part 20 and is pressed in when the two metal parts 20, 40 are put together, so that the restoring force of the spring element moves the two metal parts 20, 40 apart.
  • Analogous to the Fig. 6e shows Fig. 6f another spring element.
  • the spring element of the Fig. 6d has the advantage that a lateral insertion does not deflect the spring downwards significantly and that it can press the metal part in the locking direction even after insertion.
  • the spring of the Fig. 6f may require further guidance in the spring direction.
  • Spring elements as locking parts 66 generally have the advantage that the two metal parts 20, 40 can be put together and locked immediately.
  • the disadvantage is a significantly reduced force emanating from the locking element 60 compared to, for example, a metal wedge fitted under pressure in a press fit. This reduces the normal force on impact and contact surfaces and the contact can have a higher resistance.
  • contact surfaces 24, 26, 44, 46 and abutment surfaces 22, 28, 42, 48, and also the locking surfaces 62, 64 need not be flat with a single orientation but may also have regions of different orientations.
  • Some examples of such surface shapes are shown in Fig.7 shown.
  • a relief is shown, as would be made visible by a section through the two metal parts 20, 40. It is advantageous if the surfaces of the metal parts 20, 40 can slide along each other in a preferred direction. This can be used for the contact surfaces be ensured by the profile being constant over a direction perpendicular to the locking direction of the metal part along the locking direction of at least one of the metal parts. For example, grooves can be seen in the metal along this direction.
  • abutting surfaces 22, 28, 42, 48 a constant relief in the direction of the associated contact surface is helpful so that the metal part slides along this profile towards the contact surface.
  • Fig. 7a shows a described advantageous profile curve with an exemplary angular profile.
  • the metal parts 20, 40 interlock at the contact and abutment surfaces. In this way, the metal parts 20, 40 are guided securely. In addition, they hold together better when locked and the contact surface is larger compared to flat contact and abutment surfaces.
  • the profiling described is particularly advantageous for the contact surfaces.
  • Fig. 7b shows a first wave-shaped profile
  • Fig. 7c a concave profile of a first surface and a complementary convex profile of a second surface are shown.
  • Fig. 7d another embodiment of interlocking surfaces is shown.
  • these can be coated, in particular with softer metals such as nickel or tin.
  • softer metals such as nickel or tin.
  • Other metals such as gold or other conductive materials are also conceivable.
  • a coating is advantageously only applied in the area of the contacting contact and abutment surfaces, see coatings 70,72 in Fig. 6e .
  • the cable connector 1 described so far generally still has an unprotected metal outer surface. This has the disadvantage that it can come into electrical and mechanical contact with other conductors, and there is also the risk of corrosion or other damage due to environmental influences. In order to eliminate these risks, it is advantageous to have the cable connector 1 facing outwards. This can be done by means of a housing which is placed around the cable connector 1 after connection and locking.
  • Fig. 8a shows another advantageous embodiment of insulation from the environment.
  • the metal parts 20, 40 are coated with an insulation layer 80 on at least parts of the outer surfaces that are not contact surfaces, abutting surfaces, locking surfaces or other outer surfaces that are not to be insulated.
  • This is preferably a non-conductor and can be made of plastic, silicone, rubber, but also of ceramic, glass, etc.
  • a cover 82 can close the opening in the area of the locking element 60 after locking.
  • the cover 82 can also be part of the locking part 66, which has an insulating closure, for example, which blocks the opening when inserted.
  • the cover can also be formed as part of the housing. It is also possible for the head of the wedge to be coated with insulation.
  • the wedge can also be formed as part of the housing.
  • the insulation layer 80 can protrude over the surfaces as in Fig. 8 c, d shown.
  • a groove 84 in the projection of the insulation layer 80 on one metal part and a corresponding projection 86 engaging in the groove on the insulation layer 80 of the other metal part can enable increased insulation performance in the transition between the two metal parts 20, 40.
  • Several grooves 84 and lips 86 can also be provided, which are arranged next to one another and each engage with one another, thus increasing the sealing effect.
  • an insulation layer 80 a,b of a first metal part 20 may be softer than the insulation layer 80 c,d of the second metal part 40.
