Optical connectors with rotatable protective covers and related methods

By designing an optical connector including a connector subassembly, an inner shell, a protective cover and a housing, the axial movement of the housing is achieved by using the relative rotation of the protective cover to the inner shell, the problems of complex design and limited functionality of the existing optical connector are solved, and more efficient connector unlocking and polarity reversal are achieved.

AI Technical Summary

Technical Problem

Existing optical connectors have complex designs, poor performance and limited functionality, especially in terms of duplex connectors and polarity reversal, requiring a large number of specially designed components.

Method used

An optical connector is designed, which includes a connector subassembly, an inner case, a protective cover and an outer case. By relative rotation between the protective cover and the inner housing, the outer housing is allowed to move axially with the protective cover, depressing the end portion of the latch arm, thereby enabling unlocking and polarity reversal of the connector.

Benefits of technology

Simplifies connector design, improves performance and functionality, reduces dependence on specialized components, and enables convenient connector unlocking and polarity reversal.

Abstract

An optical connector (10) includes a connector subassembly (12), an inner housing (40) receiving a rear portion of the connector subassembly (12), a protective cover (44) extending from the inner housing (40), and an outer housing (42) coupled to the protective cover (44). The housing (42) and the protective cover (44) are configured to allow relative rotation about a longitudinal axis of the optical connector (10), but can move together along the longitudinal axis. The protective cover (44) is rotatable relative to the inner housing (40) between a locked position, in which the outer housing (42) is prevented from axial movement and depresses an end portion of a latch arm (26) of the connector subassembly (12), and an unlocked position, in which the outer housing (42) is axially movable to depress the end portion of the latch arm (26).
