Definitions

  • the present invention relates to an electrical connection element for attachment to a sheet metal part with a positive fit or by welding and for accommodating a cable connection device.
  • connection elements are widely used, especially in automobile construction and in the manufacture of household appliances, in order to create a grounded connection to the body or to a metal housing. They are often referred to as earth bolts or earth nuts, even if they are also used as current-conducting connections to sheet metal parts that are not earthed themselves but are isolated from earth.
  • the terms ground bolt and ground nut come about because these connection elements have threads, whereby a cable lug, a type of cable connection device, is clamped to a contact surface of a ground bolt or ground nut by means of a nut or a bolt. Examples of ground bolts and ground nuts are the EP-1497073B1 or the EP-1540770B1 refer to.
  • connection elements which are known per se, are connected to a sheet metal part by mechanical joining, with the forming work leading to bare metal surfaces between the connecting element and the sheet metal part and therefore to high-quality current transfer.
  • Further connection elements with threads are also known in the form of welding elements, which are attached to a sheet metal part by means of electric butt welding.
  • connection element While threaded connectors work well, the need to secure cable connectors with a nut or bolt is felt to be problematic in some respects. For one thing, she has to Connection between the connection element and the sheet metal part must be sufficiently non-rotatable that the screwing and unscrewing of the nut or bolt does not loosen the connection between the connection element and the sheet metal part and the alignment of the cable clamp and therefore the routing of the supply line can be problematic if no measures are taken to prevent twisting of the cable lug relative to the connection element. However, this also entails problems, since in the end a precise angular alignment of the connection element relative to the sheet metal part is required and this represents an additional complication when attaching the connection element.
  • connection elements designed as grounding bolts or grounding nuts and with connection elements in general, an attempt is made to keep the number of interfaces across which the current flows as small as possible, since every interface, i.e. every transition between two different components, is potentially associated with resistance losses and contamination problems is.
  • grounding bolts or grounding nuts are provided with a flange that is an integral part of the grounding bolt or grounding nut, and the cable lug is pressed directly against the flange, resulting in only two interfaces or current transfers, between the cable lug and the flange of the connection element and between the connection element and the sheet metal part.
  • special measures are taken to keep the flange free from contamination prior to the attachment of the cable lug.
  • connection elements for accommodating cable connection devices in the form of connectors is to achieve sufficient electrical contact between the connector, for example its spring cage, and the contact area of the connection element, which is maintained over a long period of time and is as little susceptible to corrosion or oxidation as possible is.
  • a metallic ring surrounds the contact area and lies tightly against the contact area by means of a permanent tension generated in the ring and has an outer surface that forms the contact surface for the cable connection device.
  • connection element has a metallic passivated coating at least in the contact area of the cable connection device, since the intrinsically insulating passivation and the coating ensure a connection element that is corrosion-resistant overall.
  • ground bolt Since the ground bolt is not only used inside the vehicle, but also outside in particular, it must be ensured that there is a high level of corrosion protection. This is generally ensured by a zinc or zinc-nickel surface with an additional passivation and, if necessary, an additional seal. However, corrosion protection always means that an attempt is made to prevent the flow of electrons as far as possible. Of course, this is counterproductive for a mass bolt where high conductivity is desired. On the other hand, the contact resistance is significantly better, the higher the surface pressure between the two partners. The disadvantages of an anti-corrosion surface can therefore be compensated for by a higher surface pressure.
  • the contact surface of the ring can be sealed off from the outside world by a suitable connection device, for example a cup-shaped cable lug, no corrosion protection is required here and a surface can be protected apply, which ensures good contact. This is all the more necessary as only low surface pressure can be applied via the springs of the cable lug.
  • a suitable connection device for example a cup-shaped cable lug
  • the ring can be shrunk onto the contact area by heating the ring and/or by cooling the connection element, or it can be attached by mechanical squeezing.
  • a permanent tensile stress is created in the ring, i.e. a type of ring stress which is necessary for the intensive interlocking or abutment of the inner surface of the ring and the outer surface of the contact area of the connection element.
  • the ring is pressed onto the contact area by mechanical squeezing, which can be done by radial and/or axial application of force, a permanent compressive stress is achieved in the ring, which also ensures that the inner surface of the ring and the outer surface of the contact area of the connection element mesh intensively .
  • a particular variant of mechanical crushing consists in laying out the ring in the manner of a cutting ring and applying it to the contact area, in a similar manner to the application of a cutting ring to a hydraulic line, except that the tool used for this purpose is there after application of the cutting ring is removed again.
  • a conical inclined surface on the connection element and a sleeve-like tool with an inner inclined surface can be used, with the ring or the cutting ring between the facing conical Inclined surfaces is pressed radially and axially in a suitable pressing device.
  • the cutting effect of a cutting ring also creates a permanent compressive stress in the ring or in the cutting ring and also an intensive meshing of the inner surface of the ring and the outer surface of the contact area of the connection element.
  • the inner edges on the end faces of the cutting ring also have a cutting effect on the surface of the contact area, which also enables excellent current transfer.
  • the ring is made of copper, a copper alloy or another metal with good conductivity. Such a design also improves the current transfer from the connector into the ring and from the ring into the connection element.
  • the ring is coated at least in the area of the contact area and preferably also in the area of the outer surface and even better over the entire surface with a material that conducts even better than the ring itself. It is even more preferred if the material of the coating is relatively is soft compared to the body of the connector. For example, the material of silver, silver alloy, gold, gold alloy or other highly conductive corrosion resistant material.
  • an electrically high-quality transition can be created between the cable connection device and the ring.
  • the full-surface coating of the ring also creates an even better current transfer between the ring and the body of the connection element. If the ring is coated over its entire surface, it may even be the case that the current flows mainly via the coating into the body of the connection element, which means that the electrical conductivity of the ring plays a subordinate role and it can therefore be made of a more cost-effective material than pure copper.
  • the connecting element according to the invention can be a ground bolt or a ground nut. However, this is not absolutely necessary since the connection element can also be used with a sheet metal part which is or is electrically insulated from a grounded metallic housing or sheet metal part.
  • connection element according to the invention is preferably intended for use with a cable connection device—possibly known per se—which has a spring cage that makes electrical contact with the outer surface of the ring and surrounds the outer surface.
  • connection element according to the invention results in an assembly component in which the connection element is welded to the sheet metal part or is attached in a form-fitting manner using a forming process.
  • the present invention also includes a method for producing an electrical contact to a contact area of a connection element, in particular an element according to one of the embodiments described above, with the special feature that a ring made of metal is heated, applied to the contact area and then shrunk onto the contact area. This creates a permanent tensile stress in the ring that maintains high quality current transfer over time and protects the interface between the ring and the connector body from oxidation or moisture.
  • connection element having the contact area is cooled, for example with liquid nitrogen and a metal ring is applied to the contact area and the connection element with the ring is brought to ambient temperature.
  • connection element with the ring is brought to ambient temperature.
  • the metal ring can be pressed onto the contact area.
  • the method can be carried out in such a way that the metal ring is applied axially to the contact area and pressed radially inwards. This creates a permanent compressive stress in the ring which also maintains high quality current transfer over time and protects the interface between the ring and the connector body from oxidation or moisture.
  • a metal ring can be used, which is designed in the manner of a cutting ring and is applied to the contact area by axial and/or radial pressing.
  • a permanent compressive stress is created in the ring, which also maintains high-quality current transfer over a longer period of time and protects the interface between the ring and the body of the connecting element (at least in the area of the end faces of the ring) against oxidation or moisture.
  • FIG. 1A and 1B An electrical connection element 10 can be seen there, which has a cylindrical rivet section 12 on the underside of the head part 14 for positive attachment to a sheet metal part. This is related to the Figures 1C and 1D explained later.
  • the electrical connection element is designed to accommodate a cable connection device that is associated with the Figures 2A and 2B and 3 will be explained later.
  • the connecting element 10 has a shank part 16 with a region 18 adjacent to the head part, which ends in an annular shoulder 20 .
  • the shank part 16 has an extension 22, with a shape that roughly corresponds to a conventional spark plug connector in the present example, namely with an upper collar 24 and underneath a cylindrical section of smaller diameter 26, which has a sloping annular shoulder 28 merges into a cylindrical area 30 .
  • the cylindrical portion 30 has a larger diameter than the cylindrical portion 26 but smaller than the portion 18 adjacent the head portion, ie the annular shoulder 20 is located between the portion 18 and the portion 30.
  • the cylindrical portion 30 is surrounded by a metallic ring 32 , which surrounds the contact area of the body of the metal terminal element 10 and by means of a permanent hoop stress generated in the ring, bears tightly against the cylindrical area 30 which forms the contact area between the ring 32 and the terminal element 10.
  • the ring 32 has an outer surface 34 which is the contact surface for a cable connector 48 ( Figures 2A and 2B ) forms.
  • the ring 32 and the region 18 of the shaft part 16 are surrounded by a comparatively soft protective sleeve 36, which is pushed down from the outer surface of the ring 32 during the installation of the cable connection device, whereby an electrical contact between the cable connection device ( Figures 2A and 2B respectively. 3 ) and the outer surface of the ring 32 is allowed.
  • the purpose of the protective cover 36 is, on the one hand, to keep the outer surface of the ring free of paint during the painting of the sheet metal part with the attached connection element 10 or to keep the outer surface of the ring free of other contamination, but to release this outer surface when the plug-like cable connection device is plugged onto it.
  • the body of the metal connection element which usually, but not necessarily, consists of steel, is provided with a metal passivated coating, which is present at least in the contact area of the cable connection device. Because this coating is very thin, the line that defines the shape of the body can be viewed as the passivated metallic coating.
  • the coating consists of nickel or a nickel alloy, for example.
  • the coating protects the body of the connector against corrosion and is often also coated with a thin film of grease in addition to the coating or the passivated coating. Both a thin film of grease and any passivation tend to be seen as insulating.
  • the ring stress can arise because the ring 32 is shrunk onto the contact area 30 by heating the ring 32 and/or by cooling the connecting element 10 or is attached to it by mechanical squeezing.
  • the ring 32 is preferably made of copper, a copper alloy or another highly conductive metal and is at least in the area of the outer surface of the ring 32, preferably also in the contact area between the radially inner surface of the ring 32 and the area 30 of the shaft part 16 and - even better - fully coated with a material that conducts even better than the ring itself.
  • the material of the coating is preferably relatively soft compared to the body of the connector. This will ensure good electrical contact the shank part 16 of the connection element and to the cable connection device.
  • the material of the coating is preferably silver, a silver alloy, gold, a gold alloy or other highly conductive, corrosion-resistant material.
  • FIG. 1C and 1D is shown as the ground bolt according to the Figures 1A to 1D takes place on a sheet metal part 40 by means of rivets.
  • the rivet section 12 is pressed in a self-piercing manner into the sheet metal part shown here as a disk.
  • the riveting can be done in a way that is well known for an SBF bolt from the applicant and therefore does not need to be explained here. It should only be expressed that fresh contact material, ie an oxide-free transition between the head part 14 of the metallic bolt element 10 and the sheet metal part 40, is produced by the self-piercing attachment. This is further promoted by the fact that the anti-twist lugs 38 of the head part are also pressed into the sheet metal material.
  • connection element instead of realizing the connection element as an element mechanically joined to the sheet metal part 40, it could also be realized as a welded element.
  • the head part instead of a rivet portion, the head part could have three or another number of welding tips, which are well known per se, and which make the initial contact with the sheet metal part 40 during the welding process, as is usual with welding elements.
  • the Figures 2A and 2B show the assembly part 44 that results when a cap 46 having a cable connector 48 similar to a spark plug connector is pressed onto the shank part 16 of the ground bolt 10 .
  • the bevel 58 at the top of the collar 24 facilitates attachment of the slip-on cap 46, and features within the cap 46 (not shown) hold the cap securely to the barrel portion 26 below the collar 24.
  • the upper bevel 58 of the collar 24 facilitates the slip-on movement and spreads the clamping device (not shown) provided inside the cap, which clamps around the cylindrical region 26 after the push-on movement and secures the cap 46 or the cable connection device against unintentional detachment from the connection element.
  • a slotted spring cage 50 Inside the plug-like cable connection device 48 there is preferably a slotted spring cage 50, which alone in 3 is shown and whose central constriction 52 forms the contact area with the outer surface 34 of the ring 32 or its coating.
  • the spring cage 50 sits tightly spread inside the cap 46.
  • the continuous longitudinal slot 54 as well as the resilient contact tongues 56 ensure that the required contact pressure on the outer surface 34 of the ring 32 comes about.
  • the protective sleeve 36 is pushed down by the outer surface of the ring 32 and assumes the bellows-like folded shape shown in FIGS Figures 2A and 2B is evident.
  • the protective cover 36 which is partially receivable in a cylindrical receptacle (not shown) of the cap 46 below the spring cage 50, forms a seal preventing contamination from entering the area of the spring cage 50 and the outer surface 34 of the ring 32 and impairs the electrical function.
  • FIGS. 2A and 2B also show a cable 38 which is connected by means of the cable connection device and the spring cage is electrically connected to the connection element 10 and the sheet metal part 40 .
  • the cable 38 can be a multi-core cable (not shown).
  • the metal ring 32 can be heated to about 200°C and shrunk onto the portion 30 of the shank portion 16 at room temperature of about 20°C. It is assumed here that the inner diameter of the ring 30 is dimensioned in such a way that at this temperature (approximately 200° C.) there is approximately a push fit on the outer diameter of the cylindrical region 30 . Upon subsequent cooling to room temperature, the ring 32 shrinks by an amount sufficient to cause the ring 32 to be firmly pressed onto the area 30, i.e. sufficient hoop stress in the ring 32.
  • the ring 32 is applied to the contact area 30 by axial and radial pressing.
  • a connector 10 in the form of a male pin-like member according to the connector Figures 1A to 1B is very similar except for the transition from the cylindrical contact area 30 to the extended cylindrical area 18.
  • This is designed here as an annular groove whose outer flank forms a conical surface 62 which diverges downwards in the direction of the central longitudinal axis.
  • the protective cover is also missing according to the Figures 1A and 1B , there this is preferably installed only after the ring 32 has been installed.
