The invention relates to a small high-density multi-
core optical fiber connector. A plurality of contact pin parts are arranged in a spline shell of a plug, contact pin pressing plates are arranged on the
tail portions of the contact pin parts, springs are arranged between the contact pin parts and the contact pin pressing plates, a fastening nut is arranged at the
tail of the spline shell, and the fastening nut tightly ejects the contact pin pressing plates through a rear ejector sleeve. A
metal shell of a socket is installed in an outer shell, each cavity of the
metal shell is provided with a
ceramic bushing, contact pin pieces are arranged in the
ceramic bushings,
ceramic bushing pressing plates are installed on the
tail portions of the ceramic bushings, and a tail nut tightly ejects the ceramic
bushing pressing plates through a contact pin ejector plate. The
optical fiber connector is small in size and high in integration level, and can be used in small space. A
viscose structure is not arranged inside a shell of the
optical fiber connector, so that the
optical fiber connector is convenient to disassemble, the whole internal structure can be taken out only by disassembling the tail of the
optical fiber connector in the maintenance process, if some parts are damaged, only the damaged parts need to be replaced, other parts cannot be scraped, and therefore maintenance cost is low.
