## 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

### Claim 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.

### Claim 2 (depends on 1)
