Light conductor plug with pin spring-mounted in axial direction - is prevented from rotating by axial groove or rib corresp. to slidable ring of complementary profiling

摘要

The plug pin (1) is non-rotatably held in the plug housing (3) to ensure a certain circumferential orientation. The outer circumference of the housing has an axial groove or rib (3b) that corresponds to complementary profiling (6a) of a slidable ring (6). This ring has a protruding nose (6b) at a certain point confirming the required circumferential orientation of the pin. The profiling of the ring can be in the form of a set of wedges. A circular spring (7) can be used to secure the ring on the front end of the plug housing. This spring fits partly in the circumferential groove of the latter and partly in the groove in the inner wall of the ring lying in the same plane. ADVANTAGE - Lowest possible attenuation.
