Abstract: In a plug connection assembly for a moisture-protected electrical plug connection having at least one plug which has a main body (1) having a fastening flange (4) on the front side and a resilient sealing element (7) arranged on said flange and an electric line cable (2) emerging rearward from the main body (1), a contact carrier (5) which receives electric contacts (6) is inserted into the main body (1) in a form-fitting manner. The fastening flange (4) can have a rigid contact area (14) for contact with a socket (9), and the sealing element (7) can have a surface seal (17) and a raised molded seal (27) on a partial surface thereof.

Abstract: A plug for a moisture-protected electrical plug connection has a plug housing having an interior and contact elements secured in the plug housing. Electrical lines extend through the plug housing and are each conductively connected by an electrical connection to one of the contact elements. The electrical lines each have an enveloping insulation. A potting compound fills out the interior of the plug housing. The electrical lines each have a first area without insulation adjoining the electrical connection. An electrically non-conductive spacer is arranged between the first area and the electrical connection. The first area, on a side of the spacer facing away from the electrical connection, is embedded in the potting compound.

Abstract: A rotary pump has a pump housing enclosing a flow space and provided with an intake opening and a discharge opening, wherein the intake opening and the discharge opening are connected to each other by the flow space. An impeller wheel is disposed in the flow space and is driven in rotation. An expansion body is provided that is fluidically connected to the flow space. A spiral casing surrounds, in a mounted position in the pump housing, an outer circumference of the impeller wheel, wherein the spiral casing is a single-part or multi-part shaped component and is embodied separate from the pump housing.
