Abstract
An array of dust shutter plate connected to a body by a flexible bridge member. The body holds one or more dust shutter plate, a corresponding bridge member, and an actuator that opens the dust shutter or moves the dust shutter plate from a closed position covering an opening in the alignment sleeve holder to an open position, so the connector ferrule can be accepted into an opening at one end of the alignment sleeve holder.
Claims14
A fiber optic adapter protecting against debris ingress, comprising:
- an adapter housing having a longitudinal axis and defining an adapter port into which a fiber optic connector can be inserted in a forward direction along the longitudinal axis into the fiber optic adapter;
- a dust shutter plate;
- a flexible bridge member, the dust shutter plate connected to the flexible bridge member, wherein the flexible bridge is deformable to move the dust shutter plate between a closed position and an open position;
- a bias spring separate from the flexible bridge member yieldable biasing the dust shutter plate toward the closed position;
- a dust shutter housing actuator integrally connected to the flexible bridge member and connected to the bias spring;
- and
- an alignment sleeve having an open end for receiving a ferrule of the optical fiber connector when the fiber optic connector is inserted into the port of the adapter housing;
- wherein a front housing of the fiber optic connector actuates the dust shutter plate from the closed position covering the open end of the alignment sleeve to the open position exposing the open end of the alignment sleeve when a ferrule is fully inserted into the alignment sleeve via the opening.
5 more elements
A dust shutter plate assembly, comprising:
- a housing with a plurality of slots;
- a retention tab received in each slot,
- a bias spring;
- the retention tab retaining the bias spring within a corresponding slot and the retention tab being movable along a longitudinal axis within the slot;
- an actuator, the retention tab being secured to one side of the actuator;
- a flexible bridge member, the actuator being connected to the flexible bridge member,
- a dust shutter plate, the flexible bridge member being connected to the dust shutter plate;
- and
- wherein the bias spring forces the dust shutter plate closed over an opening formed in an alignment sleeve;
- wherein the bias spring comprises a compression spring configured to be compressed along the longitudinal axis.
