A housing (1) for and electrical device having at least two housing parts (2) and an electrical circuit on a printed-circuit board (5) that can be attached in the housing (1) are proposed. Furthermore, a connection device for the power supply of the device and/or signal transmission to the electronic circuit that is capable of being attached to the housing (1) is provided. After the housing parts (2) are joined, one housing wall (4) that is integral with one of the housing parts (2) forms an interference radiation-proof, chamber-like recess (3) for accommodating the connection device. Furthermore, at least one electrically-conductive contact conductor tracks of the printed-circuit board (6) connected with a ground connection of the housing.

A coupling flange on a torque transmitting shaft or the like for coupling in face-to-face relationship with a counter-flange has at least two tooth systems on its coupling surface and each system comprising a plurality of substantially parallel axially projecting teeth having inclined flanks. At least one tooth in each tooth system has a different height, spacing or shape from the other teeth in the tooth system and the tooth systems are engagable with a complementary configuration on the counter-flange so as to connect nonrotatably the flanges.

An apparatus includes, in combination, an electrical component and a bracket. The electrical component has a first end configured to electrically connect to a circuit board. The electrical component defines an axis and has a width measured in a direction transverse to the axis. The bracket has a body defining a bore shaped to receive the electrical component. The body further includes a break in communication with the bore to allow expansion of the bore. In an at-rest state of the bracket, the bore has a bore width smaller than the width of the electrical component, and when the electrical component is received in the bore, the bracket is elastically deformed such that the electrical component is clamped in the transverse direction solely by the residual stress within the bracket without any additional clamp or fastener.

The invention relates to a pin (10) which can be electrically connected in a soldering-free manner to a printed circuit board, said pin comprising a punching sheet profile provided with a contact pin section (11) for a plug connector and/or a plug connector strip, a first securing section (12) for the plug connector and/or the plug connector strip, a connection section (13) and a second securing section (15) provided with a pressing-in area (16), which can be at least elastically shaped in a printed circuit board hole such that it can be adapted to the diameter of the hole. The pin (10) comprises a bearing profile (14, 18, 19) which is arranged in the punching plane and which is used for a pressing-in tool (24) and is angled away from the punching plane in a connecting section (13) thereof. An insertable and removable, after having been inserted, pressing-in tool is provided for the insertion of at least one pin

The invention relates to a multi-stage charging device for a battery of a battery operated electrical motor. The multistage charging device comprises a buck converter, an intermediate circuit and a boost converter in order to generate a suitable direct charging current from a (one or three-phase) alternating current provided by a power connection. According to the invention, components of the electrical drive are used for the boost converter and the intermediate circuit: the electrical motor functions as an intermediate circuit and the drive converter functions as a boost converter. According to the invention, the coupling of the electrical motor to the network-side buck converter occurs so that at least half the charging current flows through at least one of the at least three coils of the electrical drive. The invention further relates to a corresponding method and to a corresponding use of the drive components.
