Abstract: An electrical device includes power electronics and signal electronics. The power electronics has a sheet metal housing having a cover to form a housing, the signal electronics has a signal electronics housing which is placed on the power electronics, and the cover has a connecting tab, through which a mating plug connector part of the power electronics projects. A plug connector part of the signal electronics is connected to the mating plug connector part, a guide groove is formed in the cover, and a guide rib formed on an inner side of the signal electronics housing projects into the guide groove. At least one first centering dome is arranged on the sheet metal housing and projects towards the signal electronics housing, and a screw projects through the centering dome, which also projects through the signal electronics housing and is screwed into a threaded bore of the power electronics.

Abstract: An electrical device includes a power electronics and a line filter. The line filter has a housing, the power electronics has a sheet-metal housing, and an electrical PE connection or ground connection is formed between the sheet-metal housing and the housing by an angle bracket that includes a first limb region, a second limb region, and a yoke region, as well as a lug region. The yoke region is connected to both the first limb region and the second limb region, at least two first press-in nuts are arranged in the second limb region and at least two second press-in nuts are arranged in the lug region, and the angle bracket is pushed onto a sheet-metal region of the sheet-metal housing such that the sheet-metal region is arranged between the first and the second limb region and makes contact with the first limb region and the second limb region.

Abstract: An electrical device includes a sheet-metal housing and a fan. The fan has a fan housing that is clip-connected to the sheet-metal housing and has a pivot pin that is set against a pivot axis oriented coaxially with respect to an edge of the sheet-metal housing such that the fan can be pivoted relative to the sheet-metal housing.

Abstract: In an electrical device and method for producing a first and second electrical device from a construction kit, the electrical device includes a heat sink having a contact surface, on which a power module is arranged. A frame part of the electrical device is arranged on the contact surface, the power module is accommodated in the frame part, and the frame part is delimited by a bulge of the heat sink protruding at the edge of the contact surface.

Abstract: An electrical device, e.g., an inverter or converter, includes a first and a second printed circuit board. The first printed circuit board includes protruding tab regions, and a respective tab region protrudes into a respective recess of the second printed circuit board. Contact pins, e.g., of one or more plug connector parts, protrude into holes of the second printed circuit board.

Abstract: A converter assembly, a method for producing a converter assembly and a method for operating a converter assembly are described, in which a base module includes power electronics and control electronics. The base module includes a housing, particularly a housing part at least partially forming a housing for the power electronics and control electronics. The base module includes an electrical and mechanical interface, via which signal electronics are able to be joined to the base module with form-locking and/or force-locking, in order to form the converter assembly. The signal electronics include a housing, especially so that after being joined, the housing of the signal electronics and the housing of the base module together form a housing of the converter assembly. A setpoint value for speed and/or torque is transmittable electrically via the interface, the signal electronics having means for receiving, determining and/or inputting the setpoint value.
