A flexible connection arrangement is provided which is useful in a pressure control device for a braking system, for example, and a pressure control device utilizing the flexible arrangement is described. The flexible connection arrangement eliminates the need of an interrupting conductor, thereby reducing the number of components required in a pressure control device and reducing manufacturing cost, complexity and the size of the device. The connection arrangement includes a flexible, elastic arm which may be integrated with a bobbin of a coil, and a lead wire terminal which may be embedded in an elastic arm and extend therefrom to directly electrically connect with a control circuit board. The flexibility of the elastic arm allows relative movement between the coil and the control circuit board without damaging the electrical connections therebetween.

Pressure control 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.
