Patent number: 11444391Abstract: An electrical contacting interface includes a low and stable electrical transition resistance including at least two contacting partners, which interact for electrical contacting. According to an embodiment, in one of the two contacting partners, in the region of a contacting surface, a structure is formed which protrudes from the plane of the contacting surface of the one contacting partner. The structure deforms under the influence of a mechanical force and causes a corresponding deformation in the shape of a recess in the opposite contacting partner. The structure protruding from the plane is formed such that even after the deformation caused in the opposite contacting partner and the flat regions of the two contacting surfaces do not touch. Therefore, the electrical current is forced to flow solely through the contact interface created during the deformation process, such that the electricity transfer surfaces are precisely localized.Type: GrantFiled: November 14, 2018Date of Patent: September 13, 2022Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Peter Kaesbauer, Norbert Reichenbach

Patent number: 11425835Abstract: A switching device includes a number of line sections corresponding to a number of phases, each including a first and a second connection part, for connection to a connection phase of an electrical consumer. At least one controllable semiconductor switching element is provided per phase, wired between the first and second connection part. A bypass unit includes one controllable electromechanical switching element with a low on-resistance per phase. The controllable electromechanical switching element is wired, in parallel with the controllable semiconductor switching element of this phase, between the first and second connection part. The first and second connection part of a respective phase are arranged adjacently on one side of the power module in spatial proximity in a direction of extent. A contact bridge, assigned to a respective phase, runs in the direction of extent in order to electrically connect the first and second connection part in the switched-on state.Type: GrantFiled: February 27, 2020Date of Patent: August 23, 2022Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Peter Kaesbauer, Johannes Engelmann

Patent number: 11259439Abstract: A low-voltage switching device includes a housing in which power-electronic components are arranged in the region of ventilation of a fan. In an embodiment, the power-electronic components operate under temperature regulation by virtue of an air flow that is guided asymmetrically proceeding from the fan. Therefore, the low-voltage switching device can be operated at a nominal device current range of up to 650 A as the result of the asymmetrically guided air flow.Type: GrantFiled: November 14, 2018Date of Patent: February 22, 2022Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Peter Kaesbauer, Norbert Reichenbach

Patent number: 9793666Abstract: An electrical apparatus includes a top-hat rail mount and a first conductor connection with a clamping point. A conductor can be secured via the clamping point. The electrical apparatus can be connected to a top-hat rail via a rotational movement about a rotational axis at the top-hat rail mount. In an embodiment, the first conductor connection be embodied and arranged in such a way that in the state in which the apparatus is connected to the top-hat rail via its top-hat rail mount, the longitudinal axis of a straight conductor which is accommodated in the first conductor connection is located essentially perpendicularly with respect to a straight line which is oriented orthogonally with respect to the rotational axis and which intersects the rotational axis and the clamping point.Type: GrantFiled: August 6, 2012Date of Patent: October 17, 2017Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Peter Käsbauer, Johann Seitz
