- a compact, liquid-cooled power converter with a plurality of printed circuit boards is known from EP 1 466402 B1.
- the object of the invention is therefore to suppress interference in a device in an optimized manner or to design it to be electromagnetically compatible.
- the object is achieved with the device according to the features specified in claim 1.
- connection arrangement has a connection unit and an EMC unit, the EMC unit having a first electrical plug connector which is connected to a mating plug connector of the connection unit, which corresponds in particular to the electrical plug connector. in particular is plug-connected, wherein the EMC unit has a connection for supply lines, in particular a mains connection, in particular an AC voltage supply mains connection, in particular the supply lines supply the device with electrical power.
- the advantage here is that the EMC measures can be arranged as close as possible to the mains connection.
- the measures are arranged within the device.
- the interference suppression and/or measure required in each case can be optimally adapted by the plug-in connection, since the EMC unit can be exchanged for another EMC unit with the same plug connector and measures optimally adapted to the respectively changing requirements.
- a series of devices can thus also be designed in which the EMC unit can be designed differently for different variants of the series.
- the measure is directly connected to the grid connection.
- the measure thus acts directly, in particular by avoiding long line lengths arranged between the measures and the electronics of the device.
- the EMC unit has components for improving the electromagnetic compatibility and/or for interference suppression, in particular with a printed circuit board being equipped with the components and the first plug connector.
- the advantage here is that the EMC measures are mechanically connected as a unit.
- the EMC unit thus represents a module that can be connected to the connection unit, which also represents a module. This is because the connection unit is also connected to the electronics, in particular converter electronics, of the device via connectors, with a connector part for energy and a connector part for data being fitted on a circuit board of the connection unit for this purpose.
- the EMC unit has a mains choke and/or Y-capacitors, in particular the or a circuit board being equipped with the mains choke and/or the Y-capacitors and the first plug connector.
- the EMC unit has a housing that is formed from a lower part and an upper part.
- the advantage here is that the housing provides protection, but in particular provides electrical insulation. Thus, security is increased.
- the housing is arranged inside the housing of the device and therefore does not have to be designed to be watertight or with a high degree of protection, whereas the housing of the device can be designed with a high degree of protection, in particular watertight. If the device is an electric motor, in whose terminal box the EMC unit is arranged, the terminal box surrounds the housing, forming a housing and with a high degree of protection.
- the housing encloses the components and/or the mains choke, the Y capacitors and the first plug connector, forming the housing.

- an area of the upper part is shaped as a partial area of a hollow cylinder, the partial area comprising an end face of the hollow cylinder and a jacket section of the hollow cylinder.
- the advantage here is that the partial area follows the contour of the mains choke, which itself has a cylindrical shape. The partial area thus at least partially encloses the mains choke.
- the distance between the partial area is, for example, constant or always smaller than a maximum distance value.
- the partial area has first slits running through the upper part, with the first slits each extending radially in relation to the cylinder axis of the hollow cylinder and being spaced apart from one another in the circumferential direction, in particular evenly, in particular with each of the first slits in the radial direction the same radial distance range, in particular in relation to the cylinder axis, covered and/or wherein the first slots are formed geometrically identical to one another.
- the advantage here is that convective cooling is made possible, since air currents are driven convectively in the intermediate space area between the mains choke and partial area when the mains choke is heated.
- the first slits enable a flow from the intermediate space area into the external environment and vice versa.
- the partial area has further slits running through the upper part, with the further slits extending both partially over the casing section and partially in the end face, in particular coming from radially outside, in relation to the cylinder axis of the hollow cylinder.
- the advantage here is that an improved through-flow is made possible in that an air flow can flow in at the further slot in the area of the lateral surface and can flow out to a first slot, that is to say at the end face.
- the further slots are spaced apart from the first slots, in particular spaced apart in the circumferential direction.
- the radial spacing region covered by the first slots overlaps with the radial spacing region covered by the further slots, in particular in the radial direction, in the radial direction.
- the radial distances are related to the cylinder axis of the hollow cylinder.

- the cover is designed in at least two parts, i.e. in particular it consists of two parts, the two parts of the cover being clip-connected to one another, the connection direction when the two parts are clipped in parallel to the direction of actuation of the first connector, in particular the cover, the
- the upper part and the lower part are made of plastic, in particular for the electrical insulation of the printed circuit board or the EMC components.
- the printed circuit board is equipped with one or the grounding plate, in particular with the grounding plate being connected to a metallic housing part of the device by means of screws.
- the advantage here is that the grounding can be carried out easily and two or more screws are used. A secure connection of the housing part to the grounding plate can thus be achieved.
- the grounding plate is preferably L-shaped and placed with its long leg of the L on the printed circuit board and soldered.
- the device is an electric motor with a connection box, the connection arrangement being arranged in the connection box, in particular the connection box having a cover in which a converter is arranged in an integrated manner.
- a converter can be arranged integrated in the connection box together with the EMC measures, which are therefore arranged in a protected manner in the metallic connection box of the electric motor.
- the EMC measures can be connected directly to the connection unit via the first connector and can be arranged in the lower part of the connection box, with the electronics of the converter being arranged in the cover of the connection box.
- the device is a converter, within the housing of which the connection arrangement is arranged.
- the advantage here is that simple production is made possible.
- the EMC unit can be exchanged for another EMC unit or, when manufacturing a converter, one of the EMC units stored in a modular system can be selected, so that the appropriate EMC measure can be installed. Further advantages result from the dependent claims.
- the invention is not limited to the combination of features of the claims. For the person skilled in the art, there are further meaningful combinations of claims and/or individual claim features and/or features of the description and/or the figures, in particular from the task and/or the task posed by comparison with the prior art.

- FIG. 4 exposes a printed circuit board 40 of the connection arrangement by removing a region of a cover.
- connection arrangement has an EMC unit which is electrically plug-connected to a connection unit by means of an electrical plug connector 5 .
- the EMC unit can thus be easily exchanged for an EMC unit of a different size if the plug connector 5 is unchanged.
- connection arrangement is arranged in a device not shown in the figures.
