  • Patent number: 11852874
    Abstract: In accordance with the following description, an optical communication connector includes a ferrule having retractable alignment pins that are actuable between an extended position and a retracted position. For example, the connector may include an inner housing assembly having optical fibers and an outer housing positioned over the inner housing assembly. The outer housing is shaped to be removable from the inner housing assembly, which has a movable pin clamp mechanically coupled to alignment pins for aligning the connector with another connector. The pin clamp may be slid from a first position (corresponding to a male gender) to a second position (corresponding to a female gender). Separately or in combination with changing gender, the polarity of a communication connector may be changed due to its inclusion of an asymmetric polarity-changing feature that is actuable by an installer to change a polarity of the communication connector.

  • Patent number: 8702317
    Abstract: An optical connector having an optical fiber inserted into a connector main body includes a buckling regulating section whose length in an optical fiber insertion direction is formed variable and which regulates a buckling of the optical fiber while becoming short in an optical fiber insertion direction when the optical fiber is inserted into the connector main body. Even if an insertion area is made long, since no buckling of the optical fiber is generated, the buckling regulating section can sufficiently increase an insertion force of the optical fiber. Thus, even when foreign substances such as dusts enter and an insertion resistance increases, the optical fiber can be securely inserted. Further, the buckling regulating section is very advantageous to realize an end surface preparation of the optical fiber making use of the insertion force of the optical fiber such as a coating removing of the optical fiber, and an end surface grinding preparation of the optical fiber.
