Coupling configuration for coupling an optical plug with a plug pin to a mounting tubelet
View Patent ↗A coupling configuration enables the coupling of an optical plug with a plug pin to a mounting tubelet wherein at least one optical conductor is arranged in at least one ferrule. The coupling configuration is formed with sleeve having a first and a second coupling region, and a further mounting tubelet. The first coupling region holds the mounting tubelet, and the second coupling region holds the further mounting tubelet. The further mounting tubelet is plugged at one of its ends onto a ferrule end, projecting from the first mounting tubelet, and is centered with respect to that end. The other end of the second mounting tubelet serves for holding the plug pin of an optical plug. The invention permits mechanical decoupling of the operation of plugging and coupling a plug pin from the operation of adjusting and positioning the light-guiding structures contained in the waveguide tubelet.
