Electrical coil, in particular for solenoid valves
An electrical coil has a coil body, at least one face-end flange of the coil body, at least one mount for coil wire on the face-end flange, and one tonguelike insulation displacement contact for contacting the coil wire in the mount. Two intersecting slots of different depth are embodied on the mount, and the coil wire rests on the bottom of the slot of lesser depth, while the tonguelike insulation displacement contact is received in the slot of greater depth. Since the slot of lesser depth, in the region of its bottom, has a width which is less than the diameter of the coil wire, the coil wire is firmly clamped in the mount. The electrical coil is particularly useful for use in magnet valves.
1. An electrical coil ( 10 ) for magnet valves, the coil comprising
a coil body ( 11 ),
at least one face-end flange ( 14 ) of the coil body ( 11 ),
at least one mount ( 16 , 17 ) for coil wire ( 18 ) on the face-end flange ( 14 ),
one tonguelike insulation displacement contact ( 23 ) for contacting the coil wire ( 18 ) in the at least one mount ( 16 , 17 ), the at least one mount ( 16 , 17 ) having two intersecting slots ( 21 , 22 ) of different depth, the coil wire ( 18 ) resting on the bottom of the slot ( 21 ) having the lesser depth and the tonguelike insulation displacement contact ( 23 ) being received in the slot ( 22 ) of greater depth,
the slot ( 21 ) of lesser depth having a width, in the region of its bottom, that is less than the diameter of the coil wire ( 18 ), and
the mount ( 16 , 17 ) having an exposed step ( 28 ), extending in the plane of the bottom of the slot, on which step the coil wire ( 18 ) is braced while excess residual length is being cut off.
