Abstract

An optical fiber adapter according to the present disclosure includes a main body and an elastic shutter member. The main body has an accommodation room defined by a first wall, a second wall, a third wall and a fourth wall, wherein the first wall faces the third wall and connects with the second and fourth walls. An indentation is formed outside the accommodation room and on the third wall. The shutter member includes a fixing portion positioned within the accommodation room and on the third wall, a shutter plate, a connecting portion connecting the fixing portion with the shutter plate, and a hooking portion extending from the connecting portion to hook on to the indentation on the third wall. The shutter plate extends from the connecting portion and into the accommodation room.

Claims

1. An optical fiber adapter, comprising:

a main body having an accommodation room defined by a first wall, a second wall, a third wall and a fourth wall, the first wall facing the third wall and connecting with the second and fourth walls, wherein an indentation is formed outside the accommodation room and on the third wall; and

an elastic shutter member, including;

a fixing portion positioned within the accommodation room and on the third wall;

a shutter plate;

a connecting portion connecting the fixing portion with the shutter plate; and

a hooking portion extending from the connecting portion to hook on to the indentation on the third wall;

wherein the shutter plate extends from the connecting portion and into the accommodation room.

2. The optical fiber adapter as claimed in claim 1, wherein the hooking portion has a first vertical portion, a horizontal portion and a second vertical portion, the first vertical portion extends from the connection portion, the horizontal portion extends from the first vertical portion and is positioned outside the accommodation room and on the third wall, the second vertical portion extends from the horizontal portion and into the indentation on the third wall.

3. The optical fiber adapter as claimed in claim 2, wherein a recess is formed on the third wall, the horizontal portion of the hooking portion is positioned in the recess.

4. The optical fiber adapter as claimed in claim 1, wherein two protrusions are formed on the third wall, each of the protrusions comprising:

a vertical portion extending from the third wall; and

a horizontal portion extending from the vertical portion, wherein a gap is formed between the horizontal portion and the third wall;

wherein the fixing portion of the shutter member has two opposing sides and each of the two opposing sides is positioned between the third wall and the horizontal portion of one of the protrusions.

5. The optical fiber adapter as claimed in claim 1, wherein the shutter member is made of metal.

6. The optical fiber adapter as claimed in claim 1, wherein the optical fiber adapter is an SC type optical fiber adapter.

7. The optical fiber adapter as claimed in claim 1, wherein the indentation extends through the third wall into the accommodation room.

8. A shutter member for an optical fiber adapter, the optical fiber adapter including a main body having an accommodation room defined by a first wall, a second wall, a third wall and a fourth wall, the first wall facing the third wall and connecting with the second and fourth walls, wherein an indentation is formed outside the accommodation room and on the third wall, the shutter member comprising:

a fixing portion;

a shutter plate;

a connecting portion connecting the fixing portion with the shutter plate; and

a hooking portion having a first vertical portion, a horizontal portion and a second vertical portion, wherein the first vertical portion extends from the connection portion, the horizontal portion extends from the first vertical portion, and the second vertical portion extends from the horizontal portion;

wherein the shutter plate is configured to extend into the accommodation room, the fixing portion is configured to be positioned within the accommodation room and on the third wall, and the second vertical portion is configured to extend into the indentation on the third wall.

9. The shutter member as claimed in claim 8, wherein the shutter member is made of metal.
