Patent attributes
The invention provides an optical adapter with a shutter which can shorten a total depth dimension of an adapter main body by reducing a radius of two doors in a rotating direction, and can also achieve a firm coupling of two doors to a plug insertion port side. In an optical adapter with a shutter in which an adapter main body having a plug insertion port inserted a rectangular casing-shaped optical connector plug and formed into a horizontally long rectangular opening shape is equipped with a shutter for closing a plug insertion port so as to freely open and close, and biased each other in a closing direction by an elastic member, the shutter is constructed by two doors respectively rotated inward when the shutter is pressed by an optical connector plug inserted into the plug insertion port and vertically divided into two sections so as to be arranged vertically.
