The invention relates to a small high-density multi-
core optical fiber connector. A plurality of pin parts are arranged in the spline housing of the plug, a pin pressing plate is arranged at the
tail of the pin parts, and a There is a spring, and the fastening nut is arranged at the
tail of the spline housing, and the fastening nut tightens the pin pressing plate through the rear top sleeve; the
metal shell of the socket is installed in the outer shell, and each chamber of the
metal shell is installed There is a
ceramic sleeve, and a pin insert is also arranged in the
ceramic sleeve, a
ceramic sleeve pressure plate is installed at the
tail of the ceramic sleeve, and the tail nut tightens the ceramic sleeve pressure plate through the pin top plate. The
optical fiber connector of the present invention is small in size and high in integration, and can be used in a small space. There is no
adhesive structure inside the housing of the
optical fiber connector, and it is easy to disassemble. When maintaining, only the tail part needs to be removed to remove the entire internal structure. Taken out, if a part is damaged, only the part needs to be replaced, and the rest of the parts will not be scrapped, and the maintenance cost is low.
