[0001] The invention relates to an electric machine with a connector having at least one circular plug. State of the art

[0002] Known connectors and electrical machines of the type mentioned above have the disadvantage of comparatively low flexibility. Furthermore, known connectors of the type mentioned above generally do not offer additional functions that would be desirable for use in some target systems.

DE 86 24 397 U1 describes a medical supply unit. DE 20 2008 008 610 U1 describes a locking socket. DE 10 2013 009 216 A1 describes a receiving device for the reliable provision of electrical energy. Description of the invention

[0004] It is therefore an object of the present invention to improve an electrical machine and a connector of the type mentioned above in such a way as to reduce or avoid the disadvantages of the prior art.

[0005] In preferred embodiments, this problem is solved by an electric machine according to claim 1.

[0006] This allows, for example, different operating states of the connector and / or a target system containing the connector (i.e., the electric machine) to be visually indicated. A particularly advantageous aspect is that this eliminates the need for separate optical signaling devices, as these are already integrated into the connector according to the embodiments. This also eliminates the need for separate mounting of optical signaling means, for example, on the housing of the target system, thus reducing design effort and associated costs. Furthermore, it is advantageous to have different versions of the connector according to the embodiments, which differ, for example, in the number and / or arrangement of light sources. Depending on the target system, a suitable version of the connector can be selected and used.

[0007] In further preferred embodiments, the flange is provided to have several light transmission areas, with at least one light source assigned to each of the several light transmission areas, and in particular, at least one light source is arranged in the area of ​​one of the several light transmission areas.

[0008] In further preferred embodiments, it is provided that the or at least one of the light transmission areas has a through-opening through the flange.

[0009] In further preferred embodiments, a light guide is provided in the through-opening.

[0010] In further preferred embodiments, it is provided that the or at least one of the light transmission areas has an area with translucent or transparent material.

[0011] In further preferred embodiments, at least one support plate, in particular a circuit support plate, is provided, wherein in particular the support plate is arranged substantially parallel to the flange and is preferably detachably connected to the flange.

[0012] In further preferred embodiments, the at least one light source is arranged on the carrier plate.

[0013] In further preferred embodiments, the at least one circular connector is arranged on the carrier plate, for example, electrical connections of the circular connector are connected to the carrier plate, e.g., by means of appropriate solder joints. Alternatively, the at least one circular connector can also be connected to the carrier plate purely mechanically, for example, held by it, and electrical contact to a target system or electronics of the target system can be established by separate electrical conductors (e.g., stranded wire).

[0014] In further preferred embodiments, the flange is provided to have a marking on a first surface.

[0015] In further preferred embodiments, it is provided that the at least one light source is arranged in the area of ​​a second surface of the flange, which is opposite the first surface.

[0016] In further preferred embodiments, it is provided that the at least one light source has at least one light-emitting diode, LED, in particular a light-emitting diode which is designed to selectively emit light of at least three different colors.

[0017] In further preferred embodiments, the electrical connections of the circular connectors are not connected to the electrical connections of the at least one light source. This results in a defined separation of the respective connections from one another. In further preferred embodiments, the at least one light source can, for example, be controlled by a driver circuit of a target system for the connector.

[0018] For example, by utilizing the principle of embodiments, a rotating electrical machine such as an electric motor or a generator, or a linear motor, or a stationary electrical machine such as a transformer, can be provided.

[0019] Further aspects relate to an electrical component with at least one connector according to the embodiments. For example, by utilizing the principle of the embodiments, an electric brake, a sensor, or another electrical component can advantageously be provided with the connector.
