Power feeder for solenoid valves

Claim 1

In a power feeder for solenoid valves that supplies power from a feeding terminal on a printed wiring board fastened to a manifold base to a receiving terminal of a plurality of solenoid valves mounted on said manifold base, the improvement which comprises: rails extending in a direction in which said solenoid valves are disposed side by side, said rails being provided on one side of said manifold base; a plurality of U-shaped brackets each having a width corresponding to one of said solenoid valves, said brackets each having an engaging shoe adapted to slide along said rails while engaged therewith without detaching therefrom, and a plurality of said brackets being fitted over said rails for fastening the same number of solenoid valves to said manifold base with said printed wiring board being supported on an opposite side wall of the brackets; a terminal box disposed at one end of the group of said connected brackets, said terminal box having a feeding terminal connected to a receiving terminal of said printed wiring board by means of a cable connector passed through at least some of said brackets; a receiving terminal provided on a surface of each solenoid valve, which faces said printed wiring board; a plurality of feeding terminals provided on the printed wiring board, each of said feeding terminals on the printed wiring board corresponding to said receiving terminal of one said solenoid valve, and a plurality of base plates placed over the printed circuitry on said printed wiring board, said base plate having a plurality of openings through which said feeding terminals are projected, respectively, whereby said feeding terminals on said printed wiring board are adapted to be directly connected to said receiving terminals of said solenoid valves by mounting said solenoid valves onto said manifold base.
