Patent ID: 8512605

Claim:
A method for verifying tolerance of a connector molding die, the method comprising: providing a first connector molding die; molding a first optical connector using the first connector molding die, the first optical connector comprising a first transparent body having a first transmission surface, a plurality of first blind holes defined in the first transparent body, and a plurality of lenses positioned on the first transmission surface corresponding to the first blind holes; locating centers of the lenses relative to a center of the first transmission surface; providing a second connector molding die; molding a second optical connector using the second connector molding die, the second optical connector comprising a second transparent body having a second transmission surface and a plurality of second blind holes defined in the second transparent body, the second optical connector not comprising lenses, the center of the first transmission surface being the same as that of the second transmission surface, and accordingly central locations of the first blind holes being the same as those of the second blind holes relative to the center of the first and second transmission surfaces respectively; determining the central locations of the first blind holes by measuring the central locations of the second blind holes based on the center of the second transmission surface; and determining difference values between the locations of the centers of the lenses and the central locations of the corresponding first blind holes.
