Description

Technical Field

[0001] The utility model relates to the technical field of connection components, in particular to an outdoor waterproof pre-connection component. Background Art

[0002] Outdoor connection component optical cables and fiber optic heads are widely used in ODN. The main function of the optical cables in the connection components is to provide optical transmission channels between the OLT optical line terminal and the ONU optical network unit. ODN is an important component of the FTTH fiber-to-the-home network. It is built based on PON passive optical network equipment and is functionally divided into feeder optical cable subsystem, distribution optical cable subsystem, drop line optical cable subsystem and optical fiber terminal subsystem.

[0003] The comparative document, application number CN201921821100.5, provides a preconnector and communication equipment, which includes a connector assembly and an outdoor assembly. The connector assembly includes a ferrule base and a ferrule that can slide relative to the ferrule base. The ferrule base is used to fix the optical cable, and the ferrule is used to connect with the optical fiber of the optical cable inserted into the ferrule base; so that the optical fiber can be connected to the communication equipment through the ferrule. The outdoor assembly includes a main shaft that is sleeved on the ferrule base and fixed to the ferrule base; and a handle sleeve sleeved on the main shaft. The outdoor assembly serves as a connecting part with a detachable fixed connection to the communication equipment to provide a locking force when the communication equipment is connected. The preconnector is directly connected to the optical cable by adopting the ferrule base, and the handle sleeve and the main shaft are made into a modular structure. When assembling the preconnector, it is only necessary to sleeve the outdoor assembly on the optical cable, which facilitates the assembly of the preconnector.

[0004] The comparative document, application number CN202222321957.9, relates to a miniaturized adapter, a pre-connector assembly and a pre-connection box, and belongs to the field of optical fiber connector technology. The miniaturized adapter includes: a plug sleeve, which is used to insert the connector; an elastic arm, which is used to snap-connect the connector and is located on the circumference of the plug sleeve; a locking pressure ring, which is slidably connected to the plug sleeve and is used to lock one end of the elastic arm on the connector. A miniaturized adapter of the present application is provided with a plug sleeve that is inserted into the connector, and an elastic arm that is snap-connected to the connector. When the connector is inserted into the plug sleeve, the elastic arm of the adapter snaps into contact with the connector to achieve locking of the connector and the adapter. A locking pressure ring that locks one end of the elastic arm on the connector is slidably connected to the plug sleeve. The locking pressure ring prevents the elastic arm from falling off the connector to improve the reliability of the connection between the connector and the adapter.
