A brake pressure control device is provided in which the external wiring can be eliminated to enable a more compact design, and simultaneously, the power supply to the motor is more reliably waterproof. The wiring for the power supply conductors 51, 60 of the motor is passed internally through the valve block 30 of the brake pressure unit 10, and the electrical terminals of said power supply conductors 51, 60 are connected electrically to the control substrate 23 of the electronic control unit 20.

Brake pressure control device

The present invention provides a crack-free electrical connection structure between electrical components and a circuit board in a connector device by soldering electrical wires to through-holes of the circuit board. Retention members (40) formed integrally with the connector device have slots (36) and channels (58, 62) intersecting inside the slots (36). Projections (54) are located at an exit of each channel (58). Ends of electrical wires (90) are stripped to expose core conductors (92) and they are bent in a generally L-shape to be disposed in the respective channels (58, 62) of slots 36. The projections (54) keep the exposed core conductors (92) in position, thereby simplifying electrical connection with through-holes in the circuit board.

Electrical connection structure of connector device

The object of this invention is to decrease the ratio of contact faults by way of releasing the physical stress acted on the electric connecting portions. It settles dispersions of positions of the terminals by using elasticity of the bushing (50) with being attached the bushing (50) to the body (21) of coil unit (20), being held to be pierced terminals (23, 23) extended from the coil (22) out the bushing (50). The flexibility of the conductive sheet (40) gets rid of stress acted on the connecting portions with the terminals (23) by being electrically intermediated with the flexible conductive sheet between each terminal (23, 23) of the coil (22) and the controlling board (32) of the electric controlling unit (30).

Pressure control device integral formed the electric controller

A pressure control device includes a hydraulic unit with a plurality of pressure control valves, a coil unit with a plurality of coils each operating one of the valves, and an electronic controlling unit controlling the coils. Each of the hydraulic unit, the coil unit, and the electronic controlling unit are separately formed. Additional structure is provided to physically and electrically connect the controlling unit and the coil unit.
