A sealing sleeve for a stator of an electrical machine is disclosed. The sealing sleeve is configured to provide that a coolant flowing around the stator coils follows a predefined, serpentine coolant path. The sleeve has two sealing rings arranged on the stator with the coils of the stator lying between them. Each sealing ring includes a hard component and a soft component. The sleeve is arranged on the stator such that sealing sections of the soft component bear against the surfaces of the stator coils and adapt to the coil surfaces. As such, no coolant may pass between the coils and the sealing rings at these sealing locations thus formed, and therefore the desired coolant flow is guaranteed. Furthermore, the sealing rings are configured such that alternately for each coil only one of the sealing rings has a sealing section so that ultimately the serpentine coolant flow is achieved.

An electrical module contains at least one electrical component which is accommodated in a module housing. The module housing has at least two housing parts which lie one on the other and, on their own or together with one or more further housing parts of the module housing, delimit the interior of the module housing. There is at least one adhesive layer between the two housing parts, the adhesive layer adhesively bonding the two housing parts to one another.

A power semiconductor module includes at least two power semiconductor units that are interconnected and that have controllable semiconductors. Each semiconductor unit is associated with a cooling plate to which the semiconductors are connected in a heat-conducting manner. The object is to provide a semiconductor module that is compact and cost-effective and at the same time explosion-proof. The power semiconductor module of the invention has a module housing which houses the power semiconductor units. The cooling plates form at least part of the module housing.

The vacuum switch is compact, requires little effort, and provides a reliable current path having a high current-carrying capacity between the terminals of the vacuum switch, particularly at high switch-on speeds. The vacuum switch has a vacuum chamber, in which a vacuum is present and in which a switching contact is arranged. The switching contact includes a fixed contact piece firmly connected to the vacuum chamber and in electrical contact with a fixed contact terminal, and a moving contact piece movably guided relative to the fixed contact piece. The moving contact piece is at a distance to the fixed contact piece in a disconnect position and contacts the latter in a contact position. A drive unit produces a drive movement. A switching mechanism is connected to the drive unit and the moving contact piece and includes a conductor section that is electrically conducting up to the moving contact piece. A connector connects a moving contact terminal electrically to the moving contact piece in the contact position. The connector has a clamping contact, which has an insertion clamping contact piece connected to the conductor section of the switching mechanism and a mating clamping contact piece firmly connected to the vacuum chamber and electrically connected to the moving contact terminal. The insertion clamping contact piece and the mating clamping contact piece are arranged relative to each other such that the insertion clamping contact piece is clamped with the mating clamping contact piece in an electrically conducting manner as a result of the drive movement.
