Miniature relay with double air gap magnetic circuit
Abstract
Abstract A MINIATURE RELAY IS PROVIDED INCLUDING A STURDY, BOXLIKE ELECTROMAGNET UNIT MOUNTED IN SPACED RELATION TO A BASE. ONE SIDE OF THE BOX-LIKE STRUCTURE INCLUDES FIRST AND SECOND POLE PIECES MAGNETICALLY CONNECTED TO THE SOURCE OF ELECTROMAGENTIC ENERGY. AN ARMATURE UNIT WHICH COMPRISES AN ARMATURE AND A CONTACT ACTUATING LEVER ARM IS MOUNTED FOR ROTATION ABOUT AN AXIS EXTERIOR TO THE DIMENSIONS OF THE ARMATURE. THE ARMATURE IS FREE OF ENGAGEMENT WITH THE POLE FACES WHEN THE ELECTROMAGNETIC ENERGY SOURCE IS DEENERGIZED. WHEN THE SOURCE IS ENERGIZED, THE ARMATURE MOVES THROUGH THE AIR GAPS BETWEEN ITSELF AND THE FIRST AND SECOND POLE PIECES RESPECTIVELY. ONE FACE OF THE ARMATURE CONTACTS BOTH POLE PIECES, CLOSING THE MAGNETIC CIRCUIT BETWEEN THEM. IN ONE FORM, THE POLE PIECES HAVE SURFACES IN A COMMON PLANE.
