Abstract
The present invention provides an inexpensive and easily manufactured adapter and optical module receptacle which can prevent light from leaking where an optical connector is disconnected, wherein a roughly L-shaped shutter plate (3) is attached in the housing (1) for fitting and insertion of an optical connector by utilizing a supporting plate. In the state where the shutter plate is attached, the roughly L-shaped erectable portion (7) of the shutter plate (3) is erected so as to shield light that is transmitted to the optical connector insertion port (2) of the housing (1). In the state where an optical connector is fitted in the housing (1), the corresponding erectable portion (7) is folded by the optical connector to ensure that the corresponding optical connector receives light. Where the optical connector is disconnected from the housing (1), the abovementioned erectable portion (7) is erected by its resilient restorative force, wherein the light is shielded and is prevented from leaking to the outside of the housing (1) through the optical connector portion (2).
