Claim:
An optical fiber connector, comprising: a plurality of optical fibers; a connector body comprising a first side surface, a second side surface parallel to the first side surface, an upper surface perpendicularly interconnected between the first side surface and the second side surface, and a plurality of optical lenses arranged at the first side surface, the connector body including a plurality of first recesses defined in the upper surface and exposed at the second side surface, a plurality of second recesses defined in the upper surface and arranged between the first recesses and the optical lenses, a plurality of separating portions separating the first recesses from the second recesses, and a plurality of through holes passing through the second side surface, the first recesses, the separating portions, and the second recesses, each of the second recesses comprising an inner side surface, the inner side surface being perpendicular to a line along a lengthwise direction of the corresponding through hole and being opposite to the separating portion, the optical fibers received in the respective through holes, and passing through the respective first recesses, the respective separating portions, and the respective second recesses, and aligned with the respective optical lenses; and a plurality of positioning members received in the second recesses respectively, each positioning member comprising a first engagement post, a second engagement post, and a third engagement post, the three engagement posts corresponding to one of the through holes and surrounding a receiving room, the three engagement posts perpendicularly extending from the inner side surface toward the second side surface, the three engagement posts and the corresponding separating portion cooperatively retaining the corresponding optical fiber in the connector body; wherein the center of the receiving room coincides with the center of the corresponding optical lens, the three engagement posts are evenly distributed around the center of the receiving room, each optical fiber comprises a main portion consisting of a core portion and a cladding portion surrounding the core portion, and a front portion consisting of an exposed core portion proximate to the main portion, the main portion passes through the through hole of the separating portion and is held by the separating portion, the front portion is received in the receiving room, and the three engagement posts cooperatively retain the front portion, a lead angle portion is formed in a side of each of the separating portions adjacent to the first recess, the lead angle portion communicates with the through hole and surrounds the through hole, the end surface of the optical fiber abuts against the inner side surface, and the inner side surface coincides with the focal plane of the optical lens.
