US Patent 10295755 Fiber optic adaptor assembly having removable connector holder

A fiber optic adaptor assembly, to be inserted into a metal faceplate of a fiber distribution hub, includes a main body, a connector holder and a conductive ring member. The connector holder is removably inserted into an installation hole of the main body. The conductive ring member is removably sleeved around an outer periphery of the main body. The conductive ring member electrically contacts and cooperates with the metal faceplate to provide a shielding effect against electromagnetic interferences when the main body is inserted into the faceplate.
