Abstract: The invention relates to an electrical feed-through unit for penetration of electrical contacts through the wall of a housing of an electric motor. It has a pin made of an electrically conducting material, which is surrounded by an electrically insulating material. The pin possesses an at least partially wedge-shaped contact surface for the area of a penetration through the wall of the housing and is able to be arranged with the sheath surrounding it in an at least partially wedge-shaped borehole penetrating through the wall of the housing. In addition, the invention relates to a housing of an electric motor, which contains at least one such electrical feed-through unit as well as an electric motor which has such a housing.What is advantageous with the design of an electric motor proposed here, is that, through savings in assembly time and assembly expense, as well as parts costs, it is possible to assemble the motor components in the motor housing very simply and favorably, and additionally a number of advantages are offered as compared to use of conventional glass-to-metal feed-through (GTMS). The openings in the motor housing required for the electrical feed-through units are small, resulting in improved pressure resistance and stiffness of the motor housing. The cross-sectional surface to be sealed is also small, and as a consequence, the rates of leakage and permeation are low.
