Electro-hydraulic unit for controlling the breaking pressure in a hydraulic braking system of a vehicle

An electro-hydraulic unit for regulating a brake pressure of a hydraulic vehicle braking system, comprising a hydraulic block including a hydraulic pump;

• an electric motor connected with said hydraulic block for driving said hydraulic pump;
• an electronic control unit attached to a side of said hydraulic block opposite from said electric motor;
• at least one electrical contact which connects said electric motor to said electronic control unit in an electrically conductive manner;
• a rod-shaped insulator in which said electrical contact is contained, said insulator with said electrical contact being inserted through a throughhole in said hydraulic block, which passes through said hydraulic block from a side of said hydraulic block to which said electric motor is attached, said insulator and said electrical contact being movable at least partially in a lateral direction, said electrical contact being formed as a blade contact that protrudes from said insulator at both ends, said insulator being expandable over only a part of its length;
• spreader elements disposed toward a free end for expanding said insulator and pushable apart from each other by said electrical contact, said electrical contact expanding said insulator so that in a vicinity of said spreader elements, said insulator rests without play in said throughhole of said hydraulic block.
