Power feeding system for solenoid valve assembly

A power feeding system for a solenoid valve assembly, which comprises manifold bases, each having a plurality of openings on a mounting surface for supplying and discharging pressure fluid to and from a solenoid valve, and solenoid valves, each having a plurality of ports, each port arranged to be connected to one of said openings on the mounting surface of one of said manifold bases, said openings and said ports communicating with each other when said solenoid valve is installed on the manifold base, wherein:

• a solenoid terminal for supplying power to the solenoid is provided on one end surface of the solenoid valve so that a socket for power feeding can be directly connected thereto;
• a wiring box having a power feeding terminal connected to a power source, said wiring box being removably mounted on one end surface of a manifold base;
• a relay socket having a conductive fixture to be electrically connected with the solenoid terminal;
• power feeding pins for electrically connecting the conductive fixture to the power feeding terminal of the wiring box when the solenoid valve is installed on the manifold base;
• said conductive fixture has a plurality of squeezers;
• each power feeding pin is formed in an inverted L-shape and comprises a horizontal sector for insertion in one of said plurality of squeezers of said conductive fixture, and a vertical sector for electrical connection to the power feeding terminal of the wiring box;
• and
• the solenoid terminal protrudes from the solenoid and is inserted in other of said plurality of squeezers of the conductive fixture to connect electrically when the relay socket is mounted on the solenoid.
