DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

[0019] FIG. 1 shows a sectional view of the connection of a connection wire A, I to a stud-shaped metallic connection element M. The connection wire, which comprises both insulated wire sections I and insulation-stripped wire sections A, is wound around the connection element M. In the figure, turns with the insulated wire section I at the lower end of the connection element M are represented. In order to obtain a reliable electrical connection, the turns of the insulation-stripped wire section A are soldered to the connection element M. During soldering, the solder L is distributed over the upper part of the connection element M, and thus covers all the turns of the insulation-stripped wire section A. The insulated wire section I, conversely, only lies in contact with the connection element, and is susceptible to deformation by any tensile forces arising. Such a tensile force can be generated by the cyclic temperature in the soldered joint. By means of the turns having an insulated wire section, the connection shows sufficient flexibility to accommodate thermal strain in the connection wire. Additionally, the insulation in the insulated wire section I possesses a degree of flexibility, and can also accommodate tensile forces, by means of a variation in cross-section.

[0020] FIG. 2 illustrates the connection between the connection wire and the connection element M, in a perspective view. The connection wire respectively comprises a turn having an insulation-stripped wire section A and an insulated wire section I. The turn having the insulation-stripped wire section A is soldered to form a reliable connection with the connection element M. The solder covers all the turns in the insulation-stripped wire section A and the underlying connection element M. The turns of the insulated wire section I are not covered with the solder L The insulated wire section I, down-circuit of the final turn, leads to an electrical component B, which is located in the direction of the arrow P. Here, the connection wire is electrically connected to the component. The potentially arising tensile force is oriented parallel to the arrow direction P indicated.

[0021] The embodiment of the connection between the connection wire and the connection element is not limited to that represented in the figures, or to the embodiments otherwise described.
