Abstract

An optical fiber adapter is provided. The adapter includes a plurality of walls which defines an accommodation room adapted for being coupled with an optical fiber connector. A protrusion in the accommodation room is disposed on one of the walls. The adapter further includes a shutter member having a first parallel portion, a second parallel portion substantially parallel to the first parallel portion and a connecting portion connecting the first and second parallel portions. The first and second parallel portions and the connecting portion together define a clamping portion. The clamping portion clamps the protrusion. An elastic shutter plate extends from the first parallel portion and into the accommodation room.

Claims

1. An optical fiber adapter, comprising:

a plurality of walls which define an accommodation room adapted for being coupled with an optical fiber connector, wherein the plurality of walls comprise at least a first wall and a second wall opposite to the first wall;

a first protrusion disposed on the first wall and in the accommodation room; and

a shutter member including;

a first parallel portion;

a second parallel portion substantially parallel to the first parallel portion, the second parallel portion being positioned within the accommodation room;

a connecting portion connecting the first and second parallel portions, wherein the first and second parallel portions and the connecting portion together define a clamping portion, the clamping portion clamps the first protrusion; and

an elastic shutter plate extending from the first parallel portion and into the accommodation room.

2. The optical fiber adapter as claimed in claim 1, further comprising:

a second protrusion opposite to the first protrusion, disposed on the second wall, wherein the clamping portion clamps the second protrusion.

3. The optical fiber adapter as claimed in claim 2, wherein the second protrusion is positioned within the accommodation room.

4. The optical fiber adapter as claimed in claim 1, wherein

the accommodation room has an entrance through which the optical fiber connector is inserted into the accommodation room,

at least one opening other than the entrance is formed through one of the plurality of walls, and

the shutter member further comprises:

at least one protrusion portion protruding from the second parallel portion, wherein the protrusion portion protrudes from within the accommodation room to an outside of the accommodation room through the opening.

5. The optical fiber adapter as claimed in claim 1, wherein the angle between the shutter plate and the first parallel portion is greater than 140 degrees.

6. The optical fiber adapter as claimed in claim 1, wherein the shutter member is integrally formed and made of metal.

7. The optical fiber adapter as claimed in claim 1, further comprising:

an elastic sheet connecting to the second parallel portion, and adapted to push the elastic shutter plate toward an original position of said elastic shutter plate.

8. A shutter member for an optical fiber adapter, the optical fiber adapter having a plurality of walls and a protrusion disposed on one of the walls, wherein the walls define an accommodation room adapted for being coupled with an optical fiber connector, the protrusion is disposed in the accommodation room, the shutter member comprises:

a first parallel portion;

a second parallel portion substantially parallel to the first parallel portion;

a connecting portion connecting the first and second parallel portions, wherein the first and second parallel portions and the connecting portion together define a clamping portion, the clamping portion is adapted for clamping the protrusion, and wherein the second parallel portion is positioned within the accommodation room when the clamping portion clamps the protrusion of the optical fiber adapter; and

an elastic shutter plate extending from the first parallel portion, wherein the shutter plate extends into the accommodation room when the clamping portion clamps the protrusion of the optical fiber adapter.

9. The shutter member as claimed in claim 8, wherein the accommodation room has an entrance through which the optical fiber connector is inserted into the accommodation room, at least one opening other than the entrance is formed through one of the walls, the shutter member further comprises:

at least one protrusion portion protruding from the second parallel portion, wherein the protrusion portion protrudes from within the accommodation room to an outside of the accommodation room through the opening when the clamping portion clamps the protrusion of the optical fiber adapter.

10. The shutter member as claimed in claim 8, wherein the angle between the shutter plate and the first parallel portion is greater than 140 degrees.

11. The shutter member as claimed in claim 8, wherein the shutter member is integrally formed and made of metal.

12. The shutter member as claimed in claim 8, further comprising:

an elastic sheet connecting to the second parallel portion, and adapted to push the elastic shutter plate toward an original position of said elastic shutter plate.

13. An optical fiber adapter, comprising:

a plurality of walls which define an accommodation room adapted for being coupled with an optical fiber connector, wherein the plurality of walls comprise at least a first wall and a second wall opposite to the first wall;

a first protrusion disposed on the first wall and in the accommodation room; and

a shutter member including;

a first parallel portion;

a second parallel portion substantially parallel to the first parallel portion;

a connecting portion connecting the first and second parallel portions, wherein the first and second parallel portions and the connecting portion together define a clamping portion, the clamping portion clamps the first protrusion; and

an elastic shutter plate extending from the first parallel portion and into the accommodation room, wherein the angle between the shutter plate and the first parallel portion is greater than 140 degrees.
