Abstract:
13fiber optic modular connector system which includes a receptacle connector (30) and a locking leaf spring (17) having a locking tang (17c) mounted on the receptacle connector. The connector system further includes a removable plug connector housing (19) carrying a rotatable coupling ring (23) for selective coupling with the receptacle connector. The coupling ring includes external splines (25) for accepting a connector installation and removal tubular wrench (50), and further includes a plurality of notches (27) for cooperating with the locking leaf spring to provide a rachet mechanism. The notches on the coupling ring and the locking leaf spring on the receptacle connector allow the coupling ring to be rotated in a first direction, and prevent rotation in a second direction when the locking tang of the leaf spring is engaged with one of the notches on the coupling ring. The disclosed connector system further includes a connector installation and removal tubular wrench (50) which has an elongated housing (35) and an internally splined socket (39) for selectively meshing with and engaging the external splines of the plug connector coupling ring. An elongated slot (47) extending from the end of the socket along the housing is provided to allow the tubular wrench to be placed over a removable plug connector having a fiber optic cable connected thereto.
Abstract:
A connector (13) is provided with a rotationally spring-loaded coupling ring (21) having a set of thread segments (139) distributed around its front end. A pair of identical such connectors (13) may be quickly interlocked by pressing the connectors together and twisting their coupling rings in mutually opposite directions. Also disclosed is an alignment tube segment (47) which when interfitted with its identical counterpart forms an alignment tube for precisely maintaining a pair of contact bushings (111) on a single axis. A tool (211) designed to install such an alignment tube segment into the disclosed connector is also disclosed.
Abstract:
A precision guide assembly (11) comprising a receptacle (13) having an at least part-cylindrical passage (19) with an axis (27), a guide pin (15) sized to be inserted into the passage (19) of the receptacle (13) and having an axis (31). The guide pin (15) has a part-spherical head (33) and an at least part-cylindrical stem (35) joined to the head by a neck (37). The stem (35) and head (33) have substantially the same diameter and a lesser diameter than the diameter of the passage (19) so that the guide pin (15) can be slid into the passage (19). The neck (37) has a cross-sectional dimension less than the diameter of the stem (35) and an inclined surface (39) which is inclined with respect to the axis (31) of the guide pin (15) so that the inclined surface (39) extends radially inwardly as it extends distally.
Abstract:
A fiber optic terminus (11) comprising a body (13) having a passage (43) therein and a longitudinally compressible and radially expandable coupling element (15) in the passage. The coupling element (15) has a passage (60) therein adapted to receive a portion of an optical fiber (23). An axial force is applied to the coupling element (15) by a plunger (17) and a spring (19). The coupling element (15) is compressed axially and expanded radially to retain the optical fiber (23) in the passage (60) of the coupling element.
Abstract:
A coupling mechanism (11) comprising a receptacle (13) having an open cavity (31) therein, a plug (15) receivable in the cavity (31), and a rotatable coupling member (17) drivingly coupled to the plug (15) and coupling the plug (15) to the receptacle (13). A locking member (19) is mounted on the coupling member (17) for rotation with the coupling member (17) and for translation relative to the coupling member (17). A spring (21) acts between the locking member (19) and the coupling member (17) and urges the locking member (19) to translate with the coupling member (17). Translation of the locking member (19) is limited so that the spring (21) is compressed to store energy. A cam track (33) and a cam follower (105) have interlocking members which are driven into interlocking relationship by the stored energy in the spring (21) when the locking member (19) and the receptacle (13) are in a predetermined angular position relative to each other. The interlocking members retain the locking member (19) against rotation relative to the receptacle (13).
Abstract:
Un connecteur (13) est pourvu d'une bague d'accouplement (21) armée rotativement par un ressort ayant un ensemble de segments filetés (139) répartis autour de son extrémité frontale. Deux de ces connecteurs identiques (13) peuvent être mutuellement verrouillés rapidement en les assemblant à pression et en tournant leurs bagues d'accouplement dans des directions opposées. Un segment de tube d'alignement (47) est également décrit lequel, lorsqu'il est interadapté à sa contre-partie identique forme un tube d'alignement pour maintenir de manière précise une paire de douilles de contact (111) sur un seul axe. Un outil (211) conçu pour monter ce segment de tube d'alignement dans le connecteur de l'invention est également décrit.
Abstract:
Le mécanisme de raccordement décrit (11) comprend un élément récepteur (13) contenant une cavité ouverte (31), une douille (15) pouvant être reçue dans la cavité (31) et un raccord rotatif (17) raccordé par entraînement à la douille (15) et raccordant la douille (15) à l'élément récepteur (13). Un élément de blocage (19) est monté sur le raccord (17) pour effectuer un mouvement de rotation avec le raccord (17) et un mouvement de translation par rapport au raccord (17). Un ressort (21) agit entre l'élément de blocage (19) et le raccord (17) et force l'élément de blocage (19) à effectuer un mouvement de translation avec le raccord (17). Le mouvement de translation de l'élément de blocage (19) est limité, de sorte que le ressort (21) est comprimé pour stocker de l'énergie. Une piste de came (33) et un suiveur de came (105) comportent des éléments de blocage par interpénétration qui sont amenés à se bloquer les uns par rapport aux autres par l'énergie stockée dans le ressort (21), lorsque l'élément de blocage (19) et l'élément récepteur (13) se trouvent dans une position angulaire prédéterminée l'un par rapport à l'autre. Les éléments de blocage par interpénétration retiennent l'élément de blocage (19) pour empêcher sa rotation par rapport à l'élément récepteur (13).
