Abstract
A mold for fabricating an optical fiber connector is disclosed. The optical fiber connector includes a blind hole for accommodating an optical fiber and an aspherical lens portion for being optically coaxial with the optical fiber. The mold includes a rod-shaped core for forming the blind hole and a plate-shaped core. The plate-shaped core includes an aspherical recess for forming the lens portion. The aspherical recess faces the rod-shaped core and is adjustably movable relative to the rod-shaped core to achieve alignment between the aspherical recess and the rod-shaped core.
Description
- This application is a divisional application of patent application Ser. No. 12/979,350 filed on Dec. 28, 2010 from which it claims the benefit of priority under 35 U.S.C. 120. The patent application Ser. No. 12/979,350 in turn claims the benefit of priority under 35 USC 119 from TaiWan Patent Application 099129857, filed on Sep. 3, 2010.
- 1. Technical Field
- The present disclosure relates to a mold having movable plate-shaped cores for fabricating an optical fiber connector.
- 2. Description of the Related Art
- Optical fiber connectors are widely used as interfaces for high-speed transmission of electronic data between two electronic devices. An optical fiber connector is generally fabricated using an injection mold, and includes a male connector and a female connector coupled with the male connector. The male connector and the female connector each encompasses a lens portion, a blind hole facing the lens portion, and an optical fiber accommodated in the blind hole. How well the lens portion is positioned to be optically coaxial with the optical fiber plays a vital role in the transmission of electronic data. Therefore, a mold for fabricating the optical fiber connector that can ensure precise alignment of the lens portion to be optically coaxial with the optical fiber is needed.
- Many aspects of the present circuit board assembly could be better understood with reference to the accompanying drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the circuit board assembly. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.

FIG. 1 is an isometric, assembled view of a mold for fabricating an optical fiber connector in accordance with an exemplary embodiment. -
FIG. 2 is an isometric, exploded view of the mold ofFIG. 1 . -
FIG. 3 shows a cross-sectional view of the mold ofFIG. 1 , taken along line - Embodiments of the present mold will now be described in detail below and with reference to the drawings.
-
FIGS. 1 through 3 show amold 100 for fabricating an optical fiber connector. Themold 100 includes amale mold 10, afemale mold 20 for coupling with themale mold 10, four rod-shaped cores 30 for forming four blind holes of the optical fiber connector, two plate-shaped cores 40 for forming four aspherical lens portions of the optical fiber connector, and eightrectangular spacers 50. - The
male mold 10 includes afirst parting surface 101 and defines amolding cavity 11 from thefirst parting surface 101 toward an inner portion of themale mold 10. The rod-shaped cores 30 extend through themale mold 10 with an end portion of the rod-shaped cores 30 exposed in themolding cavity 11. Thefemale mold 20 includes asecond parting surface 202 for coupling with thefirst parting surface 101 and defines two separated throughholes 21 passing through thesecond parting surface 202. Each plate-shaped core 40 has anend surface 41 and defines two separatedaspherical recesses 42 from theend surface 41 toward an inner portion of the plate-shaped core 40. Eachaspherical recess 42 has the same shape and size as an aspherical lens portion to be fabricated. The plate-shaped cores 40 each extends through one of the throughholes 21, with theend surface 41 protruding beyond thesecond parting surface 202. -
Spacers 50 are selectively accommodated in a throughhole 21 and contact the plate-shaped core 40. The number ofspacers 50 used are however many are needed for finely adjusting alignment of the plate-shaped core 40 relative to the rod-shaped cores 30 such that each of thecavities 42 can be optically coupled with a rod-shaped core 30. - To fabricate the optical fiber connector, the
male mold 10 is coupled with thefemale mold 20 in a manner that has thefirst parting surface 101 contacting thesecond parting surface 202. That is, theend surfaces 41 of the plate-shaped cores 40 exposes in themolding cavity 11, and eachaspherical recess 42 is optically coupled with one of the rod-shaped cores 30. Molten plastic is then injected into themolding cavity 11. Hence, themolding cavity 11 and therecesses 42 are filled with the plastic, four aspherical lens portions each having the same size and shape as therecesses 42 and four blind holes each having the same size and shape as the rod-shaped cores 30 are obtained. Next, thefemale mold 20 is separated from themale mold 10, and the rod-shaped cores 30 are removed. Thereafter, four optical fibers are assembled into the blind holes. In this manner, each optical fiber is optically coaxial with a corresponding lens portion. - In alternate embodiments, the
end surface 41 is aligned with thesecond parting surface 202, and themolding cavity 11 is defined in thefemale mold 20. - It will be understood that the above particular embodiments are shown and described by way of illustration only. The principles and the features of the present disclosure may be employed in various and numerous embodiments thereof without departing from the scope of the disclosure as claimed. The above-described embodiments illustrate the possible scope of the disclosure but do not restrict the scope of the disclosure.
