摘要： A semiconductor-based fuse for the disconnecting of a charging-current path for the charging of a battery of a vehicle-side high voltage electrical system of a battery-electric vehicle includes one or more semiconductor-switch elements that are switchable in a charging-current path of the battery-electric vehicle, to enable a charging of the battery via the charging-current path. The semiconductor-based fuse includes a measurement sensor system that is connectable in the charging-current path of the battery-electric vehicle, and is to detect a current flowing through the one or more semiconductor-switch elements. The semiconductor-based fuse includes a control system, which is to switch off the one or more semiconductor-switch elements upon the reaching of a threshold value of the detected current, in order to disconnect the vehicle-side high voltage electrical system from the charging-current path.

摘要： An electronic circuit for a battery-electric vehicle for the switching-off of semiconductor switches in the event of critical currents, the electronic circuit includes at least two semiconductor switches that are connectable in parallel with one another between an energy supply source and a load. The electronic circuit includes a control unit configured to detect a current flowing through the at least two semiconductor switches, and, based on reaching a critical current, to switch off the at least two semiconductor switches. The electronic circuit includes a delay circuit connected in parallel with the at least two semiconductor switches and is configured, in the event of a not-exactly-simultaneous switching-off of the at least two semiconductor switches, to absorb a part of the critical current that switches over from at least one first-switching-off semiconductor switch to another one of the at least two semiconductor switches.

摘要： The invention relates to a plug-in connection system (1), to a plug-in connection element (2, 3) and to a plug-in connection (4). The plug-in connection system (1) comprises a locking mechanism (5), the actuating lever (6) of which is pivotably mounted on a cover (7) of the first plug-in connection element (2) and is pivotable between two lever end positions. The locking mechanism (5) is arranged, in the second lever end position, in a locking position in which a form-fitting element (9) of the first plug-in connection element (2) and a form-fitting element (11) of the second plug-in connection element (3) form a locking form-fitting engagement which tensions the plug-in connection elements (2, 3) against one another. In the first lever end position, the locking mechanism (5) is arranged in an unlocking position in which the locking form-fitting engagement is released. A securing slide (12) is mounted so as to be movable in translation in the actuating lever (6) of the locking mechanism (5) and is adjustable between a securing position, in which a securing pin (13) of the securing slide (12) engages in a securing pin receptacle (14) of the cover (7), as a result of which a securing form-fitting engagement is formed between the cover (7) and the actuating lever (6), and a securing-release position, in which the securing form-fitting engagement is released.

摘要： A network for a vehicle and a method of making the network is described. The network is suitable for a number of vehicle network subscribers in at least two topology levels which can be distinguished spatially or functionally. An energy supply device, at least one control unit, at least one interface module, a communication interface; a number of load interfaces, at least one load interface, at least one matrix coupler are provided. The matrix coupler is set up to represent an unbundling task for linking the vehicle network subscribers, where nodes of a line-connector relationship of the graph representing the matrix-coupler in each case denotes a load interface of the number of load interfaces at the end of a line. Here, an edge of the graph denotes a connection relationship of at least one line between a first load interface and a second load interface.

摘要： The present disclosure relates to a temperature measuring device for measuring a temperature of a pin-shaped electrical contact element, which includes a flexible circuit board with a first thermally conducting and electrically insulating substrate layer. The first substrate layer includes a contact surface that is configured to lie flat against a flange of the pin-shaped electrical contact element and an opening disposed in the contact surface. The pin-shaped electrical contact element is disposed at least partially in the opening. The flexible circuit board further includes a second thermally and electrically conducting layer that is disposed on a sensor surface opposite the contact surface of the first substrate layer and includes a sensor element connected to the sensor surface. The sensor element is configured to record a temperature of the pin-shaped electrical contact element when the pin-shaped electrical contact element is at least partially disposed in the opening.

摘要： A method for covering a screw head of a screw which penetrates through a workpiece surface in a sealed manner by means of a viscous coating material is disclosed. The method includes the steps of applying a first strip of the viscous coating material onto the workpiece surface at a first inclination relative to the workpiece surface, the first strip of the viscous coating material, after having been applied, at most partially covering the screw head; and applying a second strip of the viscous coating material to the workpiece surface at a second inclination relative to the workpiece surface, the second strip of the viscous coating material, after having been applied, overlapping the first strip in such a way that the screw head is fully covered, the first inclination and the second inclination being opposite one another. The invention furthermore relates to an application system.
