MINIATURIZED INNER CORE STRUCTURE FOR FIBER OPTIC PREFORMED END AND COMBINATION KIT COMPRISING SAID INNER CORE STRUCTURE

A miniaturized inner core structure for a fiber optic preformed end and a combination kit. The inner core structure comprises: an inner core main body (1), one end of the inner core main body (1) being a first connecting end, and the periphery of the inner core main body (1) being provided with a step (106); a ferrule (3), the ferrule (3) being connected to the first connecting end; and a connecting nut (6), the periphery of the connecting nut (6) being provided with an external thread (601) for matching and connecting to internal threads of different kits, and the connecting nut (6) being sleeved on the periphery of the inner core main body (1) and being limited by the step (106). The inner core structure itself can be connected to adapters, serves as a miniaturized connector, can also be assembled with different kits, is compatible with fiber optic adapters of different models, can also be assembled with a traction cap (11), and is used for pipe penetration construction.
