ABSTRACT:
A guide block assembly is provided for retaining a plurality of fiber bore forming pins and at least one guide bore forming pin in precise relation to each other during molding of a multi-fiber ferrule used in a multi-fiber connector. The assembly includes an array of fiber bore blocks each with a fiber bore therethrough to retain a respective one of the fiber bore forming pins. At least one guide bore block that defines a guide bore for retaining a guide bore forming pin is assembled with the array of fiber bore blocks. Adjoining surfaces are defined between adjacent fiber bore blocks and between the guide bore blocks and the array fiber bore blocks. The use of bores more precisely retains the pins during the molding process, and the use of blocks with adjoining surfaces allows for the machining of such surfaces to precisely establish the relationships between successive fiber bore blocks and between the array of fiber bore blocks and the guide bore blocks.
