Description

Technical Field

[0001] This utility model relates to the field of communication connector-related products, specifically a cold-shrink sealing connection shell device for optical cables. Background Technology

[0002] With the rapid development of 5G communication, the performance requirements for its FTTA base station equipment are also getting higher and higher, and the waterproof requirements for fiber optic connectors are also getting higher and higher. This is to meet the higher requirements for the interface between the connector and the equipment, and to ensure that the connector has lower loss in optical transmission in harsh environments, so as to meet the transmission performance requirements of 5G high bandwidth.

[0003] Currently, the waterproof housing of existing communication connectors mates with the LC full-duplex connector through extrusion. This requires pre-installation in the factory. After injection molding, the housing and internal components are aligned and fixed with the locking points, and a dust cap is installed, which is equivalent to a physical mechanical seal. However, when encountering blizzards or storms, the wind can cause the connector to sway and bend, creating gaps. This makes it impossible to guarantee that the waterproof connector will not be infiltrated, which will cause the transmission function to fail. Utility Model Content
