Abstract: A unitary-construction shielding system obstructs an energy source opening within a connector housing when no connector is present within the housing. The shield is at least as wide as the energy source opening and is configured to rest in a position, when no connector is present in the housing, that obstructs the laser source opening. When a connector is inserted into the connector housing, the connector supplies an obstruction force to the shielding device, causing the shielding device to remain in a deflected position. When the connector is removed from the connector housing, and the obstruction force is therefore removed from the shielding device, and the bias portion of the shielding device causes the device to return to a rest position that again obstructs the energy source opening. A method for providing a shielding system provides that the installation and removal of the shielding device may be accomplished without removing the connector from the connector housing.
