The guide pin 1 and the optical fiber 6 are housed in a guide pin groove 4 and an optical fiber groove 7 provided on the surface of the substrate 2, respectively. Guide pin groove 4 and optical fiber groove 7
Both have a square cross-sectional shape, and are provided parallel to each other in a direction perpendicular to the end surface 10 by machining on the surface of the substrate 2. Further, the depth thereof is such that the upper portions of the guide pins 1 and the optical fibers 6 substantially coincide with the surface of the substrate 2, respectively. The lid 3 is bonded to the surface of the substrate 2 with an adhesive 8 via the guide pin 1 and the optical fiber 6. However, no adhesive is applied to the guide pin 1 guide pin groove 4 and the guide pin fixing part 5.

う。The guide pin 1 is made of stainless steel, and the substrate 2 and cover body 3 are made of ceramic, glass, silicone, or other hard, wear-resistant, and dimensionally stable materials. The reason why the guide pin 1 is not bonded to the guide pin groove 4 and the guide pin fixing part is because only the guide pin 1 may be replaced later. Note that the guide pin fixing portion 5 refers to a portion of the lid body 3 that is in contact with the guide pin 1. Further, the optical fiber fixing part 9 refers to a part of the lid 3 on the optical fiber halo.

That is, the optical fiber 6 is connected. In this case, it is ideal that the plurality of optical fibers be connected one after the other, but it is unavoidable that the connection efficiency will be poor because some misalignment will occur due to the accuracy of machining.

り、接続の再現性が期待できない。(Problems to be Solved by the Invention) In the substrate-type optical connector described above, the accuracy of the outer diameter of the guide pin and the dimensional accuracy of the 7-shaped guide bin groove greatly affect the connection efficiency of optical fibers. As shown in FIG. 6, when the upper part of the guide pin 1 protrudes above the surface of the substrate 2, a gap is created between the upper part of the optical fiber halo and the optical fiber fixing part 9, so that the optical fiber halo As the backlash increases, it becomes impossible to maintain a constant positional relationship between the optical fibers.Therefore, the loss fluctuation in the connection of the optical fibers increases, and the reproducibility of the connection cannot be expected.On the other hand, the upper part of the guide bin 1 is located on the surface of the substrate 2. If the position is lower, the backlash of the optical fiber 6 can be suppressed to a minimum, but the backlash of the guide pin 1 will increase, and the loss fluctuation of the optical fiber connection will increase, as described above, and the reproducibility of the connection will be reduced. I can't expect that.

。In the board-type optical connector configured as above,
When the guide pin 1 protrudes above the surface of the substrate 2, under normal conditions there is a gap between the surface of the part of the base Fi2 having the optical fiber groove 7 and the optical fiber fixing part 9 of the lid body 3. This will cause the optical fiber halo to get stuck, but in this case, pressing force on the optical fiber fixing part is applied from above the optical fiber fixing part 9 of the lid body 3 by imitating Pole [3], and the above-mentioned gap is This eliminates the wobbling of the optical fiber halo and can minimize it. In addition, when the guide pin 1 is below the surface of the board 2, in the normal state,
A gap will be created between the guide pin fixing part 5 of the lid body 3 and the guide pin 1, causing the guide pin 1 to wobble, but in this case, the guide pin fixing part can be pressed by turning the port 12. A pressing force is applied to the guide pin fixing portion 5 of No. 3, the gap is eliminated, and the looseness of the guide pin 1 can be eliminated. In either case, the thickness of the notch groove 14 provided between the guide pin fixing part 5 of the lid body 3 and the optical fiber fixing part 9 is 173 mm, which is the thickness of the optical fiber fixing part 9. Since the guide pin fixing part 5 can be largely displaced with respect to the optical fiber fixing part 9, even if the upper part of the guide pin 1 and the surface of the substrate 2 do not match, the optical fiber groove of the guide pin 1 and the substrate 2 can be easily moved. It was possible to simultaneously press both surfaces of the portion having 7 with the lid 3. That is, the backlash of the optical fiber 6 can be suppressed to a minimum, and the backlash of the guide pin 1 can be completely eliminated, and fluctuations in the connection loss of the optical fiber are almost eliminated.

の必須要件ではない。FIG. 3 is a cross-sectional view showing another embodiment of the substrate-type optical connector of the present invention, in which a notch groove 14 is formed diagonally from above and below between the guide pin fixing part 5 and the optical fiber fixing part 9 of the lid body 3. It was established in In this case as well, the guide pin fixing portion 5 of the lid body 3
By providing the cutout groove 14 between the optical fiber fixing part 9 and the optical fiber fixing part 9, the thickness of that part is smaller than the thickness of the fiber fixing part 9, so that the same effect as described above is obtained. In the figure, since one end of the guide pin fixing part 5 rests on one end of the substrate 2, it is difficult to displace the guide pin fixing part 5 downward if only the cutout groove 14 is used. Although the cutout groove 15 is provided so that the guide pin fixing portion 5 can be easily displaced downward, it is not an essential requirement of the present invention.

When this optical connector is connected to another female optical connector to connect an optical fiber, there is almost no looseness between the optical connector and the female optical connector due to external force, which reduces the variation in connection loss. It can be almost eliminated and reproducibility of connections can be expected.
