Title: LC-TYPE OPTICAL FIBER CONNECTOR AND SC-TYPE OPTICAL FIBER CONNECTOR
Abstract:
An LC-type optical fiber connector comprising, arranged along a central axis, an insert core (1), a housing (2), a spring (3), a stopper element (4), and a tail cuff. The spring is sleeved onto the tail end of the insert core (1); a first positioning part having an anti-rotation face is arranged at the tail end of the insert core (1). A second positioning part corresponding in shape to the first positioning part is arranged at the front end of the stopper element (4). The stopper part (4) drives the insert core (1) into rotation via the first positioning part and the second positioning part matching each other. The rear end of the spring (3) is abutted against the front end of the stopper element (4). The stopper element (4) and the housing (2) are threadedly connected. A glue dispensing opening (22) used for rapid dispensing of a glue for fixing is also arranged on the housing (2). The diameter of the front end of the insert core (1) is 1.25 mm. An SC-type optical fiber connector having an identical concept. The LC-type optical fiber connector and the SC-type optical fiber are both capable of implementing 360-degree effective adjustment, thus allowing for convenient adjustment of effective matching angles, and for improvement in the matching performance of the connectors, also, both are capable of adjusting fast and slow axis angles of a polarization maintaining fiber, thus ensuring extinction ratio performance and mating performance, and are easy to assemble.
