Patent ID: 8262380

Claim:
An injection mold for manufacturing a fiber optic connector, the connector including at least one converging lens and at least one receiving hole for receiving an optical fiber, each of the at least one receiving hole being aligned with a corresponding one of the at least one converging lens, the injection mold comprising: a first mold and a second mold cooperatively defining a mold cavity, the mold cavity comprising at least one lens molding recess configured for molding the at least one converging lens; at least one insert attached to the second mold and located in the mold cavity and configured for molding the at least one receiving hole; and at least one first positioning bar and at least two neighboring second positioning bars, a dimension of each second positioning bar in cross section being substantially smaller than a dimension of the at least one first positioning bar, and the at least one first positioning bar and the at least two second neighboring positioning bars being arranged around the at least one insert to position the at least one insert, such that the at least one insert is suspended in the mold cavity and aligns with the at least one lens molding recess; wherein each of the at least one first positioning bar comprises a flat bottom surface perpendicular to a lengthwise direction of the first positioning bar, each of the at least two neighboring second positioning bars is positioned parallel to a corresponding one of the at least one first positioning bar and comprises a peripheral surface, and the two peripheral surfaces of two second positioning bars neighboring the corresponding first positioning bar have two opposite peripheral surface portions parallel to the lengthwise direction; and a combination of one first positioning bar and two corresponding neighboring second positioning bars is configured to position one of the at least one insert, wherein in each combination, the flat bottom surface of the first positioning bar cooperating with the two opposite peripheral surface portions of the two second positioning bars is configured to abut against a corresponding one of the at least one insert, so as to position the corresponding insert.
