Definitions
- connection arrangement with a metallic flat conductor and a connection console, as well as a method for connecting a connection arrangement to a component.
- Flat conductors are used more and more frequently to distribute electrical energy in automotive applications, in particular in motor vehicles, be it cars or trucks.
- Flat conductors are particularly suitable for power distribution, as from certain conductor cross-sections they have larger surfaces than round conductors and thus have an improved current-carrying capacity.
- flat conductors are used to transfer electrical energy between a battery, a starter and / or a generator.
- a flat cable serves as a so-called energy backbone for distributing electrical energy from a battery to a plurality of consumers and between a drive battery and a drive motor in electrically operated vehicles.
- the flat conductors have large conductor cross-sections.
- aluminum is used as a metallic material for the flat conductors, as it is lighter than copper.
- the object was therefore based on the task of providing a connection bracket for flat conductors which, when used in dynamic environments, guarantees a consistently low contact resistance with a long service life
- connection bracket according to claim 1 and a method according to claim 15.
- connection arrangement includes a metallic flat conductor.
- a metallic flat conductor is formed in particular from aluminum or an aluminum alloy. This can be E-aluminum or aluminum 99.5, for example.
- the aluminum can in particular be soft annealed.
- the flat conductor can be at least partially surrounded by an electrical insulator, for example made of plastic, for example silicone or PVC.
- the flat conductor can be free of insulation.
- the flat conductor can also be free of insulation in a central area. End area or middle area can be viewed as connecting areas.
- the flat conductor has a polygonal cross-sectional profile, in particular an at least square cross-sectional profile. In particular, rectangular or square cross-sectional profiles are preferred. Such a cross-sectional profile is characterized in that the flat conductor has at least two surfaces lying opposite one another and running parallel to one another in at least one connection area in the longitudinal direction.
- the flat conductor has a first through opening in the connection area.
- the through opening can e.g. be drilled, punched, sawed, milled or shaped in any other way.
- the through opening runs between the surfaces which run parallel to one another in the connection area.
- the through-opening is formed to receive a bolt, which is inserted through the through-opening to arrange the connecting arrangement on a component / as will be described below.
- the flat conductor has at least one second through opening between the surfaces in the connection area.
- This second through opening is used to accommodate a metallic connection bracket.
- a projection of the connection bracket is inserted into this second through opening, as will be described below.
- the metallic connection console can be made of aluminum or an aluminum alloy. It is also possible for the metallic connection console, like the flat conductor, to be formed from copper or a copper alloy.
- the connection bracket is designed as a flat part and has a flat area that is designed as a contact surface with the flat conductor. The contact area rests on one of the surfaces of the flat conductor in the connection area. In the connection area, the contact area and / or the surface of the flat conductor can be coated with metal, in particular nickel-plated and / or tin-plated. Alternatively or cumulatively, on the flat conductor or on the connection console the metallic coating may be provided.
- connection bracket in particular the contact surface of the connection bracket, through which an electrical current with low contact resistance can flow.
- the aim is now to make this connection at the contact surface between the connection bracket and flat conductor stable over the long term and to protect it from degradation, especially in dynamic environments.
- connection bracket have a first through recess.
- the through recess can be shaped in accordance with the through opening, for example congruent thereto.
- the through recess can also be drilled, punched, sawed, milled or shaped in some other way. If the connection bracket with the contact area is placed on the flat conductor in the connection area, the passage opening and passage recess are aligned with one another.
- the aligned first openings / recesses serve to receive a bolt, as will be described below.
- connection bracket At least one projection is formed on the connection bracket. This projection preferably protrudes essentially perpendicularly from the contact surface.
- connection bracket When the connection bracket rests against the flat conductor with its contact surface in the connection area, not only is the first through-opening aligned with the first through-opening, but the projection is also arranged in the second through-opening. In addition, the connection bracket is firmly connected with its contact surface to the flat conductor in the connection area.
- the connection bracket which is preferably formed from a different metal than the flat conductor, enables long-term stable contacting of the flat conductor via the connection arrangement with a component.
- connection console to the flat conductor
- connection console is preferably carried out by means of ultrasonic welding, friction welding, friction stir welding, resistance welding, laser welding or the like.
- a full-area or partial connection between the contact surface and the flat conductor in the connection area is made possible in particular by friction welding, in particular ultrasonic welding.
- Resistance welding is also suitable for ensuring a full-surface connection of the contact surface with the flat conductor.
- the flat conductor is thus connected to the flat conductor over a large area via the contact surface and is arranged on it in a mechanically stable manner via the projections.
- the projection protrude essentially perpendicularly from the contact surface.
- the surfaces between which the second through opening runs are preferably parallel to one another, so that the second through opening runs perpendicular to the surface.
- the projection in the second through-opening it is also preferably formed vertically on the contact surface.
- the projection is essentially cylindrical, in particular hollow-cylindrical.
- the second through-opening can have an inner jacket surface which is congruent to the outer jacket surface of the projection.
- the projection starting from the contact surface, have a longitudinal extension which is equal to the distance between the Surfaces of the flat conductor in the connection area.
- the length of the projection is thus equal to the length of the second through opening (which corresponds to the height of the flat conductor in the connection area), which means that in the inserted state the projection completely fills the through opening.
- the projection with its outer lateral surface rests at least partially, in particular completely, on an inner lateral surface of the second through-opening.
- a current flow is possible not only over the contact surface, but also the surface on which the projection rests on the inner circumferential surface of the through opening.
- a particularly good connection is achieved when the projection and the second through opening have a transition fit or a press fit.
- the projection is preferably formed in one piece with the connection bracket (the flat part).
- the connection bracket can be reshaped by cutting or non-cutting, in particular by means of punching and / or bending.
- punching When preparing the flat part, it is possible to press the projections out of the material of the flat part by means of punching.
- a one-piece design of the projection with the flat part prevents a transition resistance between the projection and the flat part.
- an end face of the projection is flush with the surface of the flat conductor.
- the surface of the flat conductor which lies on the side facing away from the connection bracket is the surface which is flush with the projection.
- the number of the second through-opening and the projections be the same. In particular, more than one second through opening and a projection are provided so that the number of mechanical connections between the connection bracket and the flat conductor is increased.
- connection bracket can be inserted into the second through openings with its projections in alignment with the first through opening.
- the second through-openings are arranged around the first through-opening at preferably equal angular distances from one another.
- the second through-openings enclose the first through-opening, that is, the second through-openings lie circumferentially around the first through-opening.
- the second through-openings are preferably located on an arc of a circle which runs around the first through-opening.
- a second flat part for example in the form of a washer, be arranged on the surface of the flat conductor lying opposite the connection bracket.
- This flat part preferably rests at least on the end faces of the projections, but in particular at the same time on the end faces of the projections as well as the surface of the flat conductor.
- a bolt which has a flange-like bolt head and a bolt pin extending from the bolt head, can be inserted into the second flat part.
- That second flat part has a receptacle for this "like, for example, an opening" bore or.
- the bolt pin is guided through the second flat part, the first through opening and the first through hole and connected to a component in such a way that the second flat part is held in a clamping manner between the bolt head and the projection.
- a clamping force can be exerted, which acts vertically on the second flat part in the direction of the flat conductor. This can be done in particular by screwing if the bolt pin is formed as a screw. This pressing force is absorbed by the projections, so that the mechanical load on the flat conductor is reduced in the connection area, which is particularly helpful for a long-term stable connection.
- the bolt is a screw bolt. This can be screwed to the component.
- the bolt press the second flat part against the projection in the connected state.
- the projection absorbs the pressing force, so that a defined pressing force of the bolt on the flat part is made possible
- the first through opening and / or the first through recess be formed as a round hole or as an elongated hole.
- connection bracket is arranged on the flat conductor. At least the one projection is inserted into at least one through-opening, several projections also being inserted into several through-openings can. This arrangement ensures that the first through-opening and the first through-opening are aligned with one another, so that a bolt can be inserted through these two.
- the contact surface of the connection bracket is joined to the surface of the flat conductor in a materially bonded manner.
- a second flat part with a hole is placed on the first through opening.
- a bolt is then inserted into the hole, the first through opening and the first through recess in order to connect the bolt to a component.
- the second flat part is clamped between the bolt and the projection.
