Electric power supply apparatus for solenoid valve manifold

摘要

A solenoid valve manifold comprises interconnected manifold blocks 2 each having a solenoid valve 1 mounted thereon. An electric circuit section of each manifold block 2 is constructed by electrically connecting, with a printed circuit board 34, a multiple-pole male connector 35 disposed on one connecting surface of the manifold block, a multiple-pole female connector 36 disposed on another connecting surface, and an electric power supplying connector 37 which is located to one side and connected to an electric power receiving connector 14 of the solenoid valve. The wiring on the printed circuit board 34 is constructed in such a manner that terminals of the multiple-pole male connector 35 that send driving signals to the solenoid valves are connected to terminals of the female connector 36 such that the driving signals thereof are shifted sequentially across each block 2 to terminals toward the electric power supplying connector 37 side. The upmost terminal is connected to the electric power supplying connector 37 and a common terminal 57 is disposed at the end of the electric power supplying connector side.
