no. 1 Embodiment approach

[0034] figure 1 It is a figure which shows 2 A of optical connector ferrules. also, figure 2 yes means figure 1 FIG. II-II cross section of the optical connector ferrule 2A shown. For ease of understanding, an XYZ rectangular coordinate system is shown in the figure. The X-axis is the front-back direction of the optical connector ferrule 2A, that is, the first direction, and the Y-axis is the width direction of the optical connector ferrule 2A, that is, the second direction. The Z axis is the height direction of the optical connector ferrule 2A, that is, the third direction.

[0035] Such as figure 1 and figure 2 As shown, the optical connector ferrule 2A has a front end 2b, a rear end 2c, an upper surface 2a, and a lower surface 2d. The upper surface 2a extends along the XY plane. The end face 2 b extends along the YZ plane, and abuts against another optical connector ferrule to be connected. The optical connector ferrule 2A has: two guide holes 21 into which gu...

Abstract

An optical connector ferrule having a front end, a rear end, an upper surface, and a lower surface includes a window opening on the upper surface, a plurality of fiber holes passing through a portion between the front end and the window along a first direction and including small diameter portions on the front end side and large diameter portions on the window side, and fiber grooves extending from the large diameter portions along the first direction and having openings in a third direction, in which the plurality of fiber holes include a first fiber hole row arranged in a second direction on a lower surface side, and a second fiber hole row arranged in the second direction on the upper surface side, and the large diameter portion in the second fiber hole row is longer than the large diameter portion in the first fiber hole row.

Description

technical field [0001] The invention relates to an optical connector ferrule. Background technique [0002] Japanese Patent No. 4200900 discloses a mold for manufacturing an optical connector ferrule. In this die, a middle die having pins for forming a plurality of optical fiber holes is disposed between the upper die and the lower die. An optical connector ferrule having a plurality of optical fiber holes is obtained by injecting and curing resin into the mold. [0003] As described above, when an optical connector ferrule is manufactured using a mold in which pins are arranged, the pins may be inclined due to shrinkage of the resin in the step of curing the resin. In this case, the optical fiber hole of the optical connector ferrule may also be inclined. Figure 15 is a diagram showing a side cross section of the optical connector ferrule 100 . Such as Figure 15 As shown, there is a tendency that, with respect to the fiber holes 102, 104 before curing shown by double-d...
