The optical fiber connector includes a main body and a pressing block. The main body defines an assembling recess and a number of positioning grooves defined in a bottom surface of the assembling recess. The positioning grooves each correspond to an optical fiber. An end of each optical fiber is received in a corresponding positioning groove, and the pressing block is received in the assembling recess. ## Claims ### Claim 1 An optical fiber connector for positioning a plurality of optical fibers, comprising: a main body defining a first assembling recess and a plurality of positioning grooves in a first bottom surface of the first assembling recess, each positioning groove comprising two opposite sidewalls and a second bottom surface; and a pressing block engaged with the first assembling recess, the pressing block comprising a pressing surface attached on the first bottom surface of the first assembling recess, an end of each optical fiber being received into a corresponding one of the positioning grooves and positioned by the sidewalls, the second bottom surface, and the pressing surface of the corresponding positioning groove; wherein the main body comprises a plurality of lens portions corresponding to the optical fibers in position, and each optical fiber is optically aligned with a corresponding one of the lens portions; wherein the main body comprises a positioning portion and an extending portion connected to the positioning portion, the first assembling recess is defined in the positioning portion, ends of the optical fibers pass through the extending portion and respectively positioned in the first positioning grooves; wherein the positioning portion comprises a first surface and a second surface substantially perpendicular to the first surface, the first assembling recess is defined in the first surface, and the lens portions are formed on the second surface. ### Claim 2 (depends on 1) The optical fiber connector of claim 1, wherein the lens portions are convex lenses. ### Claim 3 (depends on 1) The optical fiber connector of claim 1, wherein each positioning groove comprises a rib portion between each sidewall and the second bottom surface. ### Claim 4 (depends on 1) The optical fiber connector of claim 1, wherein the main body comprises a rounded edge between each sidewall and the first bottom surface. ### Claim 5 (depends on 1) The optical fiber connector of claim 1, wherein the pressing block comprises a top surface opposite to the pressing surface, and the top surface is longer than the pressing surface. ### Claim 6 (depends on 5) The optical fiber connector of claim 5, wherein the pressing block comprises two opposite slanting surfaces and two opposite end surfaces, the opposite end surfaces extend substantially perpendicularly from the top surface, the end surfaces are connected to the pressing surface by the slanting surfaces. ### Claim 7 An optical fiber connector for positioning a plurality of optical fibers, comprising: a main body defining a first assembling recess and a plurality of positioning grooves in a first bottom surface of the first assembling recess, each positioning groove comprising two opposite sidewalls and a second bottom surface; and a pressing block engaged with the first assembling recess, the pressing block comprising a pressing surface attached on the first bottom surface of the first assembling recess, an end of each optical fiber being received into a corresponding one of the positioning grooves and positioned by the sidewalls, the second bottom surface, and the pressing surface of the corresponding positioning groove; wherein the main body comprises a plurality of lens portions corresponding to the optical fibers in position, and each optical fiber is optically aligned with a corresponding one of the lens portions; wherein the main body comprises a positioning portion, the positioning portion comprises a first surface and a second surface substantially perpendicular to the first surface, the first assembling recess is defined in the first surface, and the lens portions are formed on the second surface.
