Title: Method for changing over optical fiber connection and optical fiber connector
Inventor: KOYAMA KAZUHIRO
IPC: G02B26/08
Filed: 1987-01-26
Abstract: PURPOSE:To simplify exchange of a connector and to shorten the time for changing over by joining two connectors by positioning pins and selectively exchanging the connector while grasping auxiliary pins in both sides with V- grooves of upper and lower supporting bases. CONSTITUTION:The positioning pins 5 are spanned and joined to one set of connector ferrules 3, 4 for housing the terminals of optical fibers 2. The ferrule 4 is pressed to the upper supporting base 11 and after the auxiliary pins 17 are engaged with the V-grooves 18 of the base 11, the ferrule 4 is pulled in order to exchange the ferrule 4 in this state with the 3rd ferrule. The lower supporting base 12 on which the 3rd ferrule engaged with the pins 17 and the pins 18 is previously imposed is raised and while the pins 17 are grasped by the upper and lower grooves, the two ferrules are joined by means of the pins 5. The connected state is, therefore, maintained by the pins 17 even after the pins 5 are removed. The exchange of the ferrule is thus simplified and the time for the changing over is shortened.
