  • Publication number: 20220113484
    Abstract: To provide a connector plug that makes it possible to facilitate a plurality of persons' confirmation of a connector plug before its removal or after its insertion and to prevent erroneous work. The connector plug according to the present invention has a discoloration member mounted on a gripping portion for pinching during work. The color of the discoloration member changes due to heat of a worker's fingertips when the worker pinches the connector plug or pressure when the worker pinches the connector plug. The discoloration member is discolored by one worker pinching the connector plug. Another worker looks at the discolored discoloration member, and then is able to confirm whether the connector plug is a work target.

  • Publication number: 20210389528
    Abstract: An object is to provide an optical fiber connector ferrule, a sleeve, and a method for manufacturing a ferrule member that can avoid an increase in manufacturing time and an increase in cost of optical connectors for connecting multicore optical fibers. The present invention provides an optical fiber connector ferrule, a sleeve, and a method for manufacturing ferrule member which realizes alignment of multicore optical fibers corresponding to the connection by mounting a ferrule on a multicore fiber and then cutting a ferrule member instead of aligning core positions by rotating an axis of an optical fiber and adjusting positions of cores to the ferrule, leading to simplification of a rotational alignment step.
