Connector-Actuated Safety Shutter for Laser Fiber-Optic Devices

       Disclosed is a mechanism for blocking the emission of
light from a laser fiber-optic device upon removal of the connector
from the device.

      In the figure, a molded connector receptacle 1, with openings
and recesses for shutters 2 and leaf springs 3, is shown.  Each
molded shutter 2 has pivot pins 4 on cantilevered arms which snap
into corresponding holes 5 in the receptacle 1.  The shutter 2 is
pushed closed upon connector 6 removal by a leaf spring 3 which
presses down, causing it to pivot into the closed position.  In this
closed position laser emission 7 is obstructed.  The leaf spring 3 is
snapped over the top of the receptacle 1 and retained by bosses 8
(one shown) molded in the receptacle sides.  During insertion of the
connector, the shutters are pivoted up into the opening on the top of
the receptacle and held there.

      Spring loading of the shutter assures that it will close
regardless of the orientation of the receptacle or the need to rely
on gravity.  As depicted in the figure, multiple shutters can be used
to increase the reliability of laser emission obstruction.
