Abstract
The invention relates to an electro-hydraulic unit (10) for regulating a brake pressure of a hydraulic vehicle braking system. The unit (10) includes a hydraulic block (12) with a hydraulic pump (20), an electric motor (14) for driving the hydraulic pump (20), and an electronic control unit (16), which is attached to the side of the hydraulic block (12) opposite from the electric motor (14). In order to electrically connect the electric motor (14) to the electronic control unit (16), the invention proposes embodying the electric motor (14) with a tubular insulator (40), which has spreader tabs (46) on a free end, which are pushed apart from each other by electrical blade contacts (42) that are contained in the insulator (40). The spreader tabs (46) that are pushed apart from each other rest without play in a through hole (48) of the hydraulic block (12) and position the blade contacts (42) on the hydraulic block (12).
