Abstract: A plug (2) that includes a plug frame (7) is inserted into an opening of a housing (4) and is retained by a pair of spring-like detent pieces (6) extending into the opening. Projecting portions (6a) on the detent pieces engage recess portions (15) on right and left hand sides of the plug frame. A cylindrical lug (13) is slidably mounted on the plug frame and includes an opening portion (14) and inclined surfaces (17) to permit plug removal. The inclined surfaces (17) serve as cams to lift the projection portions (6a) out of the recess portions (15) when the lug is moved rearwardly. A stopper (3) is insertable into the plug frame to block such rearward sliding motion of the lug on the frame to prevent removal of the plug from the housing. The stopper may include a locking inward projection (3d) for engaging a hole (13b) bored in the lug to block rearward motion of the lug on the plug frame.

Abstract: This invention presents a method and an apparatus for adjusting the axial orientation angle between the principal axis of a polarization maintaining fiber (PMF) and a ferrule with ease and precision. The invented ferrule is composed of a ferrule body, having a through hole into which a PMF is inserted, and a ring-shaped flange, having a keyway on the circumferential rim, installed on the outer periphery of the ferrule body. An engaging part is provided on the periphery to restrain the forward movement of the ferrule body by engaging with the flange. The invented ferrule enables adjustment of the axial angle, between the principal axis of the PMF and the keyway of the flange, to be made after adhesively bonding the PMF onto the ferrule body and polishing the end of the fiber. Therefore, the axial angle adjustment is carried out conveniently and accurately, without being affected by the processing effects, such as curing of the adhesive.
