  • Publication number: 20070232096
    Abstract: A circuit board (20) is equipped with at least one conductor path (22) and a contact element (44). The latter is adapted to mechanically engage and electrically contact an electrical conductor (66). In the region of a conductor path (22), the circuit board (20) has passthrough orifices (24, 26, 28, 30, 32). The contact element (44) has a base part (46) and feet (34, 36, 38, 40, 42) which press-fit into the orifices (24 to 32) of the circuit board (20). The contact element (44) has a contact tongue (54) that is resiliently articulated on the base part (46) and clamps the electrical conductor (66). This makes possible a secure connection from the electrical conductor (66) to the circuit board (20), e.g. for connecting a device having a large current demand.

  • Publication number: 20040263103
    Abstract: An electronically commutated DC motor comprises a stator comprising at least one stator winding (22, 24, 26), a rotor (28) electromagnetically interacting with the stator, a positive and a negative DC voltage line (76, 78) for supplying power to the motor (20), in particular from a battery (77), a full bridge circuit (74) for controlling the current in the at least one stator winding (22, 24, 26), which full bridge circuit (74) comprises a plurality of bridge arms that each comprise an upper bridge transistor (66, 80, 86) for controlling the current from the positive DC voltage line (76) to an associated terminal (68; 82; 88) of that stator winding (22, 24, 26) as well as a lower bridge transistor (70, 84, 90) for controlling the current from the relevant terminal of the stator winding to the negative DC voltage line (78).
