Embodiment Construction

[0027] figure 1 A flat conductor 1 for an on-board electrical system of a motor vehicle is shown in perspective. The insulation 2 surrounding the flat conductor 1 is removed in one region. In this region, the electrical contact element 3 is connected to the partially deinsulated flat conductor 1 by friction welding. The bolt 5 passes through the through hole 4 not shown in detail here of the electrical contact element 3 (see figure 2 ).

[0028] For example, a cable lug can be slipped onto the screw 5 , which is then pressed onto the contact area 6 by screwing. Before being screwed on, the cable lug already accommodates, for example, a cable or a wire, which is then electrically conductively connected to the flat conductor 1 via the electrical contact element 3 . Contrary to what is shown in the figure, it is possible for several such electrical contact elements 3 to be connected to the flat conductor 1 at different points by friction welding.

Abstract

The invention relates to a method for connecting at least one electrical contact element (3) to a flat conductor (1) for a vehicle electrical system of a motor vehicle, comprising the following steps:providing the at least one electrical contact element (3), which has a contact region (6) for contacting a further contact element, and which is produced at least from a stainless steel plate (S) with a curved section (7), which protrudes beyond the rest of the stainless steel plate (S); arranging the electrical contact element (3) on the flat conductor (1) with its curved section (7); carrying out a friction welding process, in which a relative movement of the curved section (7) of the electrical contact element (3) arranged on the flat conductor (1) relative to the flat conductor (1) is brought about by a friction welding tool, and a welded joint is thereby produced between the flat conductor (1) and the electrical contact element (3).

Description

technical field [0001] The invention relates to a method for connecting at least one electrical contact element to a flat conductor of an onboard electrical system of a motor vehicle. Background technique [0002] By using so-called flat conductors, preferably made of aluminum, a considerable reduction in the installation space and conductor weight of the vehicle electrical system can be achieved. Such flat conductors serve as power distributors or busbars and are routed, for example, along the floor assembly contour from the rear area to the engine compartment. It is often necessary to contact different conductors electrically conductively on such flat conductors. For this purpose, stainless steel bolts are welded to such flat conductors, for example. Then, for example, the cable lugs can be slipped over the stainless steel bolts and screwed onto them. For example, the structural height created by stainless steel bolts can have a detrimental effect. Furthermore, only de...
