Pump comprising an electric motor with plug connection in the form of an intermediate plug

A pump, comprising:

• an electric motor with a rotor which is rotatably mounted about an axis of rotation and which circumferentially surrounds a stator, the stator includes a stator core and coils wound on the stator core;
• wherein
• the windings are made of a winding wire with winding wire end sections, the winding wire end sections being electrically contacted with a circuit board;
• the rotor, the stator, and the circuit board are surrounded by a motor housing which is adjoined with a pump housing;
• the circuit board is electrically contacted to an intermediate plug to contact the circuit board with an electrical controller;
• the intermediate plug includes contacts which are injection-molded into the intermediate plug and which are electrically contacted at a first end with the circuit board, are directed at least partially radially outwards at a second end, and are introduced into a connecting region of the intermediate plug;
• and
• the connecting region is located at least partially within the housing wall of the motor housing and a connector plug with predefined plug geometry and/or plug collar coding is plugged onto the intermediate plug.
