Technical Field

The invention relates to a connection of a busbar to a further current-conducting element according to the independent claim.

Background

It is known to embody the bus bars as stamped and bent parts. When installed in a product, the bus bar is screwed to another workpiece, for example, another current-carrying element. For this purpose, corresponding bores are present in the bus bars, through which the screwing takes place. The disadvantage here is that the bus bar can only be sealed at great expense. Thus limiting the installation possibilities. A further disadvantage is the additional installation process based on the costly screwing process.

Disclosure of Invention

The object of the invention is to provide a simplified connection between a busbar and a further current-carrying element.

This object is achieved with a connection according to the features of claim 1. Advantageous embodiments of the connection according to the invention are the subject matter of the dependent claims.

According to the invention, in the connection between the electrically conductive stamped part and the electrically conductive element, the electrically conductive element has at least one end section and the stamped part has a cutout. In this case, the end section of the electrically conductive element engages in the recess of the stamped part. According to the invention, the cutout of the punch member has a predetermined contour and the end section of the conductive element has a complementary contour, so that the end section of the conductive element can be positioned in the cutout of the punch member in a rotationally fixed manner.

Furthermore, conductive elements are understood to be various types of devices by means of which stamped parts can be fastened. The conductive element can also be a part of the housing or another bus bar, with which the stamped part can be fastened.

The connection according to the invention can thus be realized without screwing or riveting. The installation effort is thereby significantly reduced, since additional screwing or riveting operations can be dispensed with. Finally, the installation space of the connection is reduced, since no additional installation space for the screw head or the rivet head has to be provided.

In an embodiment of the connection according to the invention, the contour of the indentation in the punch part can be configured non-rotationally symmetrically. Furthermore, a rotationally fixed and at the same time positively positionable connection between the two components can be provided by the contour according to the invention of the cutout in the stamped-out part and the corresponding complementary contour of the conductive element.

Furthermore, it is possible to reduce the contact resistance between the stamped part and the conductive element. As a result, less heat is generated at the connection point, and possible short circuits or current interruptions are avoided.

In an embodiment of the invention, the connection may be implemented as an interference connection (Pressverbindung). It is possible, however, that the connection can be embodied as a welded connection. Finally, it is also possible that the connection can be embodied as a combination of an interference connection and a welded connection.

Drawings

The invention is described in detail below with the aid of the figures. Wherein:

figure 1 shows a connection of a stamped part to a conductive element according to the invention;

fig. 2 shows a connection according to the invention according to fig. 1.

Detailed Description

Fig. 1 shows a connection between a stamped part 1 according to the invention and a conductive element 2. The stamped part 1 is designed here as a stamped and bent part. This means that the stamped and bent part here comprises a stamped section 1a and a subsequently bent section 1 b. The conductive element 2 is embodied as a turning, milling or turning-milling component. This means that the conductive element 2 comprises a section 2b produced by means of a turning process and/or a section 2a produced by means of a milling process.

The punch member 1 has a notch 3. The recess 3 is embodied by way of example on the end section 1c of the stamped part 1. The end section 4 of the conductive element 2 is introduced into the recess 3. The recess 3 in the punch part 1 has, for example, a contour 5, which contour 5 has a circular section 7 and a straight section 8. The end section 4 of the conductive element 2 has a complementary contour 6. In this example, the straight section 8 in the contour 5 of the cutout 3 thus prevents the cutout 3 from being rotationally symmetrical. This prevents the end section 4 of the conductive element 2, which is inserted into the recess 3 of the punch component 1, from being able to be twisted in the axial direction. Thus ensuring a well-defined positioning of the conductive element 2.

It is obviously possible that the indentation 3 may have a further contour 5 different from the contour 5 shown in fig. 1, as long as it is ensured that the contour 5 of the indentation 3 is not rotationally symmetrical.

Fig. 2 shows a further connection according to fig. 1. In fig. 2, it can be seen that the end section 4 of the conductive element 2 (which engages in the recess 3 of the punch component 1) does not pass through the punch component, but ends with the surface 1d of the punch component 1. It is obviously also possible for the end section 4 of the conductive element 2 to pass through the cutout 3 of the punch component 1 and thus project beyond the surface 1d (not shown) of the punch component 1.

The invention is fully described and illustrated with the aid of the accompanying drawings and description. The description and illustration are to be regarded as illustrative in nature and not as restrictive. The invention is not limited to the disclosed embodiments. Other embodiments or variations will occur to those skilled in the art upon a reading of the specification and a study of the drawings, the disclosure and the appended claims.

In the claims, the words "comprising" and "having" do not exclude the presence of other elements or steps. The indefinite article "a" or "an" does not exclude a plurality.
