Abstract
An LC adapter provided with a built-in light shielding plate includes a frame. One end of the frame is provided with interfaces for matching with connection members. An upper light shielding plate and a lower light shielding plate in a spliced connection with each other are disposed at a position within the frame close to the interfaces. Both the upper light shielding plate and the lower light shielding plate are hingedly connected to the frame through a return spring. When a connection member is inserted into an interface, the upper light shielding plate and the lower light shielding plate rotate relative to the frame and are separated from each other. When the connection member is unplugged from the interface, the upper light shielding plate and the lower light shielding plate are restored to the state of the spliced connection with each other.
