The invention relates to a collimation-type optical fiber connector, which comprises a collimating lens, an optical fiber, a lens sleeve, a main sleeve, a limiting nut and a clamping ring, wherein the collimating lens and the optical fiber are packaged in the lens sleeve by a gluing method; the lens sleeve is screwed with the threads of the limiting nut to be fixed through a central inner hole ofthe main sleeve; and the clamping ring is fixed to an outer step of the main sleeve through a retainer ring. By using a collimation component consisting of the collimating lens, the optical fiber andthe lens sleeve, the non-contact transmission in an optical path is realized and the coupling efficiency for an optical signal is improved; and the limiting structure formed by an axial rib on the outer surface of the lens sleeve and a notch on the inner side of the main sleeve improves the accuracy of the collimation component; therefore, the connector has the advantages of compact structure, convenient assembly and convenient mass production.
