Abstract
A coupling solenoid valve having a main valve unit and a solenoid operating unit, of which both side faces in the valve-width direction correspond to a first coupling face and a second coupling face for coupling another solenoid valve, wherein pilot valves are detachably attached to the top and bottom faces of a center base extending from an adapter block, electroconductive fittings for electrically connecting between coil terminals and board terminals of each pilot valve, and folding-type elastic terminal portions are provided on both ends, these elastic terminal portions are flexibly in contact with the coil terminals and the board terminals from the side-face direction.
Claims7
A coupling solenoid valve of which both side faces in the valve-width direction correspond to a first coupling face (8a) and a second coupling face (8b) for being coupled with another solenoid valve, said coupling solenoid valve comprising:
- a main valve unit (3) including
- a plurality of coupling communication holes (15 and 16) passing through in the valve-width direction,
- a valve hole (10) through which said coupling communication holes (15 and 16) mutually communicate, and
- a spool (6) for switching a channel accommodated within said valve hole (10);
- and
- a solenoid operating unit (4) connected with said main valve unit (3);
- wherein said solenoid operating unit (4) comprises
- an adapter block (50) attached to said main valve unit (3),
- a center base (50a) extending from this adapter block (50),
- one or two pilot valves (7a and 7b) detachably assembled to this center base (50a),
- a coupling connector (61), which is mutually connected to an insertion type when plurality of solenoid valves are coupled, for electrically connecting between the adjacent solenoid valves, and
- an electroconductive mechanism (66) for electrically connecting this coupling connector (61) to said pilot valves (7a and 7b);
- said electroconductive mechanism (66) comprises
- an electroconductive board (68) electrically connected to said coupling connector (61),
- board terminals (69a and 69b) protruding from this electroconductive board (68),
- a coil terminal (57) formed on the side face on said center base (50a) side of said pilot valves (7a and 7b), and
- electroconductive fittings (70a and 70b) electrically connecting this coil terminal (57) with said board terminals (69a and 69b);
- and
- these electroconductive fittings (70a and 70b) are supported by said center base (50a), and include elastic terminal portions (73a and 73b) formed by being folded on both end portions, and these elastic terminal portions (73a and 73b) are flexibly in contact with said coil terminal (57) and said board terminals (69a and 69b) from the side-face direction.
