A fiber optic connector is provided for mating with a complementary connecting device along a mating optical axis. The connector includes an outer housing having a forward mating end, a rear end and a resilient latch arm for latching engagement with the complementary connecting device. The outer housing includes walls at the rear end thereof substantially surrounding the optical axis to define a cavity opening rearwardly of the housing. An inner housing is fitted into the rearwardly opening cavity in the outer housing, wherein the walls of the outer housing constrain the inner housing in &ldquo;X&rdquo; and &ldquo;Y&rdquo; directions generally perpendicular to the optical axis. The inner housing includes an optical element receiving cavity communicating with the optical axis. Complementary interengaging retaining members are provided between the inner and outer housings to hold the inner housing in the rearwardly opening cavity of the outer housing against movement in a &ldquo;Z&rdquo; direction generally parallel to the optical axis.

Optical receptacle

A connector assembly includes a multi-part housing for mating with a complementary connecting device. The housing has a first housing part of a first, resilient plastic material and includes a resilient latch portion for latching engagement with the complementary connecting device. The housing has a second housing part of a second plastic material with less resiliency than the first plastic material and includes a cavity for receiving and retaining an operative component of the connector assembly.

Connector assembly with multi-part housing

A connector assembly includes a plug connector having a plug housing and a sheath movably mounted about the plug housing. A receptacle connector receives the plug connector in mated condition. A primary latch is provided between the plug housing and the receptacle connector for holding the connectors in mated condition. A release is provided on the sheath for unlatching the primary latch means in response to movement of the sheath relative to the plug housing. A secondary latch is provided between the plug housing and the receptacle connector for holding the connectors in mated condition in the event of inadvertent unlatching of the primary latch means. An interengaging press-fit rib-and-slot structure is provided between the plug connector and the receptacle connector when the connectors are mated.

Latching system for connector assemblies

A connector assembly includes a plug connector having a plug housing and a sheath mounted about the plug housing. A receptacle connector receives the plug connector in mated condition. A complementary interengaging first latch is provided between the plug housing of the plug connector and the receptacle connector for holding the connectors in mated condition. A complementary interengaging second latch is provided between the sheath of the plug connector and the receptacle connector for holding the connectors in mated condition.

Disclosed optical fiber connector adaptor includes a guide cylinder to accommodate two ferrules each attached to an end of a different optical fiber, which are to be connected to each other with their optical axes aligned by inserting the ferrules in the guide cylinder from its opposite sides. The adaptor has outer and inner hollow bodies which are adapted to telescope within each other during assembly. Each hollow body has a cylindrical holder to surround and hold the guide cylinder allowing an optical fiber connector having a ferrule at its end to be press-fit in the outer hollow body until the ferrule is inserted in the guide cylinder. The inner hollow tube permits the press-fit of a ferrule, which is attached to the end of another optical fiber, into the guide cylinder on the open side of the inner hollow body.

Adaptor for interconnecting optical fibers

A method of oblique spherical polishing of an optical connector by which a desired contact surface angle on an axis of the optical connector is obtained easily and securely without requiring additional processing. In order to form a dome of a radius R, which is oblique with the contact surface angle .theta.', at the end surface of the optical connector 20, which has ferrule 22 of which a tip 24 is beveled, the tip of the optical connector 20 is polished by tilting it with the angle .theta. which fulfills the relation
