MOLD HAVING MOVABLE PLATE-SHAPED CORE
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.

BACKGROUND
[0002] 1. Technical Field
[0003] The present disclosure relates to a mold having movable
plate-shaped cores for fabricating an optical fiber connector.
[0004] 2. Description of the Related Art
[0005] 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.

DETAILED DESCRIPTION
[0010] Embodiments of the present mold will now be described in
detail below and with reference to the drawings.
[0011] FIGS. 1 through 3 show a mold 100 for fabricating an optical
fiber connector. The mold 100 includes a male mold 10, a female
mold 20 for coupling with the male 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 eight rectangular spacers 50.
[0012] The male mold 10 includes a first parting surface 101 and
defines a molding cavity 11 from the first parting surface 101
toward an inner portion of the male mold 10. The rod-shaped cores
30 extend through the male mold 10 with an end portion of the
rod-shaped cores 30 exposed in the molding cavity 11. The female
mold 20 includes a second parting surface 202 for coupling with the
first parting surface 101 and defines two separated through holes
21 passing through the second parting surface 202. Each
plate-shaped core 40 has an end surface 41 and defines two
separated aspherical recesses 42 from the end surface 41 toward an
inner portion of the plate-shaped core 40. Each aspherical 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 through holes 21, with the end surface 41 protruding beyond the
second parting surface 202.
[0013] Spacers 50 are selectively accommodated in a through hole 21
and contact the plate-shaped core 40. The number of spacers 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 the cavities 42 can be optically coupled with a rod-shaped
core 30.
[0014] To fabricate the optical fiber connector, the male mold 10
is coupled with the female mold 20 in a manner that has the first
parting surface 101 contacting the second parting surface 202. That
is, the end surfaces 41 of the plate-shaped cores 40 exposes in the
molding cavity 11, and each aspherical recess 42 is optically
coupled with one of the rod-shaped cores 30. Molten plastic is then
injected into the molding cavity 11. Hence, the molding cavity 11
and the recesses 42 are filled with the plastic, four aspherical
lens portions each having the same size and shape as the recesses
42 and four blind holes each having the same size and shape as the
rod-shaped cores 30 are obtained. Next, the female mold 20 is
separated from the male 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.
[0015] In alternate embodiments, the end surface 41 is aligned with
the second parting surface 202, and the molding cavity 11 is
defined in the female mold 20.
[0016] 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.
