Abstract

An optical fiber adapter according to the present disclosure includes a main body, an inner housing, a cover plate and an elastic shutter member. The optical fiber adapter of the present disclosure may obstruct the light beams emitted from an accommodation room of the main body thereby preventing the eyes from exposure to the light beams.

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 the accommodation room has a first opening opposing to a second opening, and an access opening is formed on the first wall

an inner housing positioned within the accommodation room, the inner housing including;

a flange having a front surface opposing to a back surface; and

a hollow cylinder extending from the front surface of the flange;

a cover plate positioned to cover the access opening on the first wall; and

an elastic shutter member, including;

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

a shutter plate;

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

a hook extending from the horizontal portion, wherein the hook is configured to hook on to the flange;

wherein the shutter plate extends from the connecting portion and into the accommodation room to arrive in front of an opening of the hollow cylinder.

2. The optical fiber adapter as claimed in claim 1, wherein an indentation is formed on the back surface of the flange, the hook is configured to hook on to the indentation.

3. The optical fiber adapter as claimed in claim 2, wherein the indentation is formed on an edge of the back surface of the flange.

4. The optical fiber adapter as claimed in claim 2, wherein the hook comprises a horizontal portion connects to a vertical portion, the vertical portion is configured to be attached to the indentation.

5. The optical fiber adapter as claimed in claim 1, wherein the hook is configured to hook on to the back surface of the flange.

6. The optical fiber adapter as claimed in claim 1, wherein a protrusion is formed on the third wall to stop the horizontal portion from being further moved toward the flange.
