CN-224232001-U - Dustproof optical fiber adapter of preventing misplug

Abstract

The utility model provides a dustproof misplug-proof optical fiber adapter which comprises a connecting seat, wherein a first optical fiber interface and a second optical fiber interface are respectively arranged on two side walls of the connecting seat, an installation seat is fixedly arranged at the top of the connecting seat, and a first connecting arm and a second connecting arm are rotatably arranged on the installation seat. When the utility model is used, the elastic structure can limit the rotation of the first connecting arm and the second connecting arm through the elasticity of the elastic structure, so that the first protective cover and the second protective cover can always keep a close fit state with the ports of the first optical fiber interface and the second optical fiber interface, the first protective cover and the second protective cover can be effectively prevented from being separated from the ports of the first optical fiber interface and the second optical fiber interface in a vibration environment, the possibility that dust enters the interface or the interface is damaged by the wrong insertion of external foreign matters is greatly reduced, and the interface is better protected.
