LC adapter provided with built-in light shielding plate

An LC adapter provided with a built-in light shielding plate, comprising a frame, wherein one end of the frame is provided with a plurality of 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 an interface, and 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 the interface, the upper light shielding plate and the lower light shielding plate rotate relative to the frame and are separated from each other under the acting force of the connection member, and 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 under the acting force of the return spring to completely close the interface,
• wherein the upper light shielding plate comprises a body which is in a spliced connection with the lower light shielding plate, an extension part for being against the connection member and protecting the upper light shielding is provided at a side of the body close to the interface, a reinforcing rib is provided between the extension part and the body, and rounded angles are provided at positions where the body and the extension part are against the connection member.
