Ribbon type optical fiber connector

Claim 1

A ribbon type optical fiber connector comprising: an optical connector plug main body whose transverse section is a trapezoid having a groove of a rectangular transverse section on an upper face of the of the main body in a longitudinal direction, and in a longitudinal direction of a bottom of the groove having V-shaped grooves for aligning a plurality of optical fiber elements, a plate member of a rectangular transverse section having a groove of a rectangular transverse section in a longitudinal direction of a bottom of the plate member into which a cover portion of the ribbon type optical fiber is inserted, the rectangular groove being connected with the bottom of the member at a slope thereof, and an alignment sleeve, of rectangular transverse section, having a groove provided in a longitudinal direction with respect to the upper face of the alignment sleeve and into which the optical connector plug main body is pressedly put while contacting two inclined faces of the optical connector plug main body, one of the two inclined faces and the bottom face being made reference faces, the plate member being engaged at its portion in the rectangular groove of the optical connector plug main body and bonded therewith, ends of the ribbon type optical fibers are inserted from one end of the rectangular groove of the plate member and the fibers of the ribbon type optical fiber being guided into the V-shaped grooves, thus assembling into an integral body, whereby two integral bodies thus assembled are engaged while being faced with each other at the respective end surfaces in the groove of the alignment sleeve.
