Publication number: 20220113484Abstract: 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.Type: ApplicationFiled: October 9, 2019Publication date: April 14, 2022Applicant: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Masaaki TAKAYA, Yoshiteru ABE, Ryo KOYAMA, Chisato FUKAI, Kazunori KATAYAMA
