Definitions
- the present invention relates to a method for establishing an electrical connection by materially bonded joining, in particular by friction welding or rotational friction welding, of two contact parts.
- the invention also relates to an electrical connection arrangement.
- electrical conductors made of aluminum can be used for the purpose of lightweight construction, cost savings, etc.
- the area of application ranges from on-board networks with 12 V, through 48 V to high voltage with more than 60 V.
- a material different from aluminum such as copper, brass or stainless steel, is preferably used to make contact with the conductor.
- Copper in particular has comparatively good mechanical properties with a comparatively low contact resistance, which makes it suitable for making contact with electrical conductors.
- the object of the invention is therefore to create an alternative possibility for establishing an electrical connection in which different materials can also be combined with one another.
- a first aspect provides a method for producing an electrical connection and / or line arrangement by materially joining a first contact part to a second contact part.
- the procedure consists of the following steps:
- the first contact part which has a male, first joining section as a solid component with an at least substantially rotationally symmetrical profile towards the second contact part.
- the second contact part which has a female, second joining section with a hollow profile towards the first contact part.
- Cohesive joining using a friction welding tool can in particular be understood as joining by means of a friction welding process, for example rotary friction welding.
- the term solid component can be understood to mean that it is not a stranded conductor, but rather a solid material is preferably used.
- the first contact part or a part thereof can at the same time form a solid conductor of the electrical connection.
- the solid component can, for example, have a cylindrical shape.
- the female second joining section can be a type of sleeve that can also be open on both sides in order to pass the male profile through a first from one side To be able to introduce opening, while the friction welding tool, for example in the form of a dome, can be attached or introduced from the other, opposite side at a second opening.
- This process enables a wide range of combinations of different materials, particularly due to the materially bonded joining using a friction welding process which, for example, can break up oxide layers and prevent their new formation.
- a material of the first contact part can have a lower mechanical strength or lower yield point than a material of the second contact part.
- the material of the first contact part can be softer than the material of the second contact part.
- the material of the first contact part can be an aluminum material, such as pure aluminum or an aluminum alloy.
- the material of the second contact part can be, for example, a copper material or a copper alloy, brass or a stainless steel.
- the first contact part can be provided with at least one material recess formed in the first joining section.
- a material cutout can also be understood here to mean a removal of material or the like.
- the solid component can be locally weakened by the material cut-out in order, for example, to enable better deformability, compression, etc. by pressing the first and second joining section prior to friction welding. If, for example, the ductility or the flowability of the first joining section is insufficient or not sufficient on its own, the material recess can be provided for e.g. improved pressing of the hollow profile onto the solid component.
- the at least one material recess can be formed by a machining production method. For example, this can be done by drilling, cutting, milling, etc. As a result, the first contact part can be provided with the material recess in a simple manner.
- the material recess can extend along an axis of rotation of the first joining section.
- the material recess can extend along the longitudinal axis of the cylinder.
- the material recess can preferably extend over the first joining section, which at the same time can correspond to a pressing section. In this way, improved compressibility can be achieved.
- the material recess can be arranged on a lateral surface of the first joining section.
- the material recess can be designed as a type of notch, as a radially extending bore or the like. This is particularly easy to manufacture.
- the first contact part and / or the second contact part can have an electrical connection section in addition to the joining section for attaching a further contact partner or contact part.
- the connection section can be selected, for example, from: a contact tongue or contact blade, contact housing, welding surface, screw tab, screw bolt and plug element. This means that there are numerous possible uses.
- the method can furthermore have the step of attaching at least one further contact partner to an electrical connection section of the first and / or second contact part.
- the method can furthermore have the step of applying a pressing force to the first joining section and the second joining section in order to press them together after the first joining section has been introduced into the second joining section.
- the method can furthermore have the step of sheathing the first and / or second joining section after it has been plasticized or melted with an insulation material.
- a second aspect provides an electrical connection arrangement which can preferably be produced using a method according to the first aspect.
- the electrical connection arrangement comprises: a first contact part, which has a male, first joining section designed as a solid component with an at least substantially rotationally symmetrical profile, a second contact part, which has a female, second joining section with a hollow profile, the first joining section being arranged in the second joining section and integrally connected to it is.

- the first contact part 110 is connected here to a contact partner 200, which is here a type of busbar as an example.
- a contact partner 200 which is here a type of busbar as an example.
- the first contact part 110 is connected on the one hand to the second contact part 120 and on the other hand to the contact partner 200, so that a continuous current path can be formed between several contact partners via the line arrangement 100.
- the second contact part 120 can likewise be connected to a further contact partner (not shown here).
- the first contact part 110 and the second contact part 120 are made of mutually different materials, the second contact part 120 being mechanically stronger than the first contact part 110.
- the first contact part 110 can have a higher ductility than the second contact part 120.
- the first contact part 110 can be made of an aluminum material, for example.
- the second contact part 120 can be made of a copper or steel material, for example.
- the first contact part 110 and the second contact part 120 are connected to one another in a section 130, forming an integral connection.
- the first contact part 110 and the second contact part 120 are in the section 130 possibly also pressed together.
- the first contact part 110 has a male first joining section 111, which is designed as a solid component, for example a solid material, and has a rotationally symmetrical profile, which here has a cylindrical shape as an example.
- the second contact part 120 has a female second joining section 121 which is complementary to the first joining section and which is accordingly designed as a hollow profile for receiving the first joining section.
- the second joining section can therefore also be understood as a type of sleeve.
- the first contact part 110 and the second contact part 120 each have an electrical connection section 112 or 122 additional to the joining section 111 or 121 for attaching a further contact partner, such as the contact partner 200 here.
- the first connection section 122 of the first contact part 110 is here exemplarily designed as a welding lug, but can also be designed as a screw lug, etc.
- the second connection section 122 of the first contact part 110 is designed here as a screw tab, but can also be designed as a welding tab, etc.
- the first contact part 110 and / or the second contact part 120 can have an offset which is formed between the respective joining section 111, 121 and the respective connection section 112, 122.
- the respective joining section 111, 121 and the respective connection section 112, 122 can be rotated with respect to one another, in particular about their longitudinal axis.
- FIG. 2 shows a further exemplary embodiment of the line arrangement 100, the first contact part 110 here having a different connection section 112.
- the connection section 112 is not designed here as a welding lug, but is suitable for connection by means of a form fit and / or force fit, for example for a Tox connection.
- the line arrangement 100 is sheathed in each case with an insulating material 140 which is at least electrically insulating, but possibly also has a sealing function.
- FIG. 5 comprises three sub-figures 5A, 5B and 5C, each showing the first contact part 110 as an individual component. What these three exemplary embodiments have in common is that the first joining section 111 has a material recess 113. This is for example formed by a machining process, such as drilling, milling or the like.
- the first joining section 111 has, as an example of a material recess 113, a central bore, which is designed here as a blind hole, which extends at least in sections along a longitudinal extension or an axis of rotation of the first joining section 111.

- the friction welding tool is a kind of mandrel that can be moved, but also turned or rotated, for example.
- the friction welding tool 400 is guided on or partially into the second joining area 121, which is open on both sides for this purpose, so that the first contact part 110 can be brought in from a first side and the friction welding tool 400 can be brought in from a second side.
- the friction welding tool 400 is then moved, in particular rotated or rotated, at least to the first contact part 110 and / or the second contact part 120 in order to generate welding energy partial plasticizing of a part of the first joining section 111 and / or second joining section 121 facing the other contact part.
- FIG. 8 the finished connecting arrangement 110 is shown in a sectional view.
- a welded connection 131 is now formed in section 130 here.
