DETAILED DESCRIPTION

[0025] The figures contain partially simplified, schematic illustrations. Identical reference signs are used in part for like, but possibly not identical elements. Different views of like elements could be scaled differently.

[0026] Indications of direction, such as “left”, “right”, “top” and “bottom”, for example, are to be understood in relation to the respective figure and can vary in the individual illustrations with respect to the illustrated object.

[0027] FIG. 1 shows one possible embodiment of a contact element 1. The contact element 1 is configured to be solid and is, for example, worked out of a solid copper workpiece in one machining operation. The contact element 1 is therefore particularly suitable for transmitting high currents.

[0028] The electrical contact element is designed to be rotationally symmetrical with respect to its axis of symmetry SA. The contact element 1 has a connection region A and a contact region K. The connection region A has a cylindrical opening 2 and the contact region has a cylindrical passage opening 3. The opening 2 and the passage opening 3 or the main axes of symmetry thereof extend orthogonally to one another. A peripheral contact strip 4, which is illustrated slightly enlarged in FIG. 2, is arranged approximately centrally within the cylindrical passage opening 3.

[0029] The contact element 1 is guided in the plugging direction SR toward the counterpart contact element 5, as can be seen in FIG. 4. The contact strip 4 has a grid-shaped basic structure which is joined together to form a ring. The contact strip 4 defines the electrical contact points which a mating counterpart contact element 5, in this case a contact pin, forms with the contact element 1, in this case a socket contact.

[0030] The contact strip 4 preferably consists of a beryllium-containing material. In FIGS. 4 and 5, the contact element 1 is formed transparently in order that the contact strip 4 arranged in the contact region K can be seen. It can be seen in FIG. 5 that, in the plugged state, the contact strip 4 contactingly encloses the pin contact 5 penetrating through the passage opening 3. The contact strip 4 accordingly forms a contact bridge between the socket contact 1 and the pin contact 5.

[0031] The contact region K of the contact element 1 has a plugging side ST and, opposite therefrom, an outlet side AS. On the plugging side ST there is provided a recess 6, and the outlet side AS has an elevation 7 which is designed to be complementary to the recess 6. The recess 6 and the elevation 7 have a substantially rectangular cross section. As a result, the openings 2, 2′, 2″ in the connection regions A of different, but similar-type contact elements 1, 1′, 1″ can enclose an angle (α) with one another. This angular position is schematically illustrated in FIG. 7.

[0032] By virtue of the substantially square cross section of the recess 6 and of the elevation 7, the angle (α) can be equal to 90° or a multiple of 90°. In the case of different cross-sectional geometries, it is correspondingly possible for different angular positions to be achieved. Different orientations between lined-up contact elements 1, 1′, 1″ are illustrated in FIG. 6.

[0033] Even though various aspects or features of the invention are respectively show in combination in the figures, it is clear to a person skilled in the art that—unless otherwise stated—the combinations shown and discussed are not the only ones possible. In particular, mutually corresponding units or complexes of features from different exemplary embodiments can be exchanged with one another.
