ELECTROMAGNETIC COIL APPARATUS EMPLOYING A MAGNETIC FLUX ENHANCER, AND ACCESSORY AND ELECTRICAL SWITCHING APPARATUS EMPLOYING THE SAME |
摘要 |
An electromagnetic coil apparatus includes a ferrous coil frame having a first end and a second end opposite the first end. A coil assembly includes a conduit, a number of coils within the ferrous coil frame and being disposed on the conduit, and a ferrous plunger movable in the conduit. A first ferrous heel member is disposed proximate the first end of the ferrous coil frame. A second ferrous top plate member has an opening and is disposed proximate the second end of the ferrous coil frame. A magnetic flux enhancer is external to the conduit and is at least partially external to the ferrous coil frame. The magnetic flux enhancer includes a ferrous conduit coupled to the second ferrous top plate member and cooperates with the opening thereof to form a passageway. A portion of the ferrous plunger of the coil assembly passes through the passageway.
