Optical connector module
There is provided an optical connector module in which an adhesive is interposed between a lens and a distal surface of an optical fiber, wherein the module includes a transparent positioning device and an optical fiber fixed in the positioning device. The positioning device has a lens provided to an end surface, a concave insertion portion into which the optical fiber is inserted and which is disposed so that the bottom surface in contact with the distal surface of the optical fiber is positioned opposite the lens, and a debris receiving portion that extends from the bottom surface in a radial direction of the optical fiber and has a surface continuous with the bottom surface.
1. An optical connector module comprising a transparent positioning device and an optical fiber,
the transparent positioning device including a lens, a concave insertion portion, and a debris receiving portion,
the lens being provided at a first exterior surface of the transparent positioning device,
the concave insertion portion extending from a second exterior surface of the transparent positioning device to an interior surface of the transparent positioning device located within the transparent positioning device proximate the lens, the second exterior surface being located at an opposite side of the transparent positioning device relative to the first exterior surface,
the debris receiving portion extending from a third exterior surface of the transparent positioning device such that the interior surface at least partially defines the debris receiving portion, the debris receiving portion providing a debris receiving space in the area surrounding the interior surface, the debris receiving portion extending lengthwise in a first direction and the concave insertion portion extends lengthwise in a second direction that is perpendicular to the first direction; and
the optical fiber being inserted into the concave insertion portion from the second exterior surface and contacting the interior surface.
2. The optical connector module according to claim 1 , wherein
the transparent positioning device includes at least one fitting portion.
3. The optical connector module according to claim 2 , wherein
the fitting portion includes a pair of concave fitting portions disposed on opposite sides of the lens on the first exterior surface of the transparent positioning device.
4. The optical connector module according to claim 1 , wherein
the concave insertion portion is aligned with the lens such that the interior surface coincides with one surface of the lens.
5. The optical connector module according to claim 1 , wherein
the lens and the transparent positioning device are unitarily formed as a single monolithic element.
6. The optical connector module according to claim 1 , wherein
the lens protrudes outward from the first exterior surface of the transparent positioning device.
7. The optical connector module according to claim 1 , wherein
the debris receiving portion has a width measured perpendicular to the first direction and the second direction, and
the concave insertion portion has a diameter that is smaller than the width of the debris receiving portion.
8. The optical connector module according to claim 1 , wherein
the concave insertion portion extends in a direction that is parallel to the third surface of the transparent positioning device and the debris receiving portion extends in a direction perpendicular to the third surface.
9. The optical connector module according to claim 1 , wherein
with the optical fiber inserted into the concave insertion portion and contacting the interior surface, a circumferential end section of the optical fiber is exposed within the debris receiving portion.
