Abstract: A pump assembly has an electrical drive motor arranged in a stator housing (8) and has an electronics housing (18) which is connected to the stator housing (8) and in which at least one circuit board (40) with electronic components is arranged. At least one separate connection element (48; 62), which is designed a plastic shaped part, is arranged on or in the electronics housing (18). The connection element includes a first electrical plug connector (52; 66), connected to a corresponding electrical plug coupling on the circuit board (40), as well as a second electric plug connector (54; 68) connected to the first electrical plug connector (52; 66) via strip conductors (54). The second electric plug connector (54; 68) serves for the electrical connection of a component situated outside the electronics housing (18).

Abstract: A pump assembly with an electric motor which includes a stator housing (6) and an electronics housing (4; 50) fastened at the outside on the stator housing (6). The electronics housing (4; 50) is connected to the stator housing (6) via at least one fastening element (24, 24′; 56). The fastening element is situated within an outer contour of the electronics housing (4; 50) which is delimited by the outer walls of the electronics housing (4; 50) and is accessible even with a closed electronics housing (4; 50).
