とは光ファイバ６上の蓋体３の一部分をいう。A conventional board-type optical connector will be described with reference to FIGS. 4 and 5. FIG. FIG. 4 is a perspective view of a conventional board-type optical connector, and FIG. 5 is a side view thereof. In the figure, 1 is a guide pin,
2 is a substrate, 3 is a lid, 4 is a guide pin groove, 5 is a guide pin fixing portion, 6 is an optical fiber, 7 is an optical fiber groove, 8
Is an adhesive, 9 is an optical fiber fixing portion, and 10 is an end face. The guide pin 1 and the optical fiber 6 are accommodated 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 V-shaped cross section, and are provided on the surface of the substrate 2 by machining so as to be parallel to each other in a direction perpendicular to the end face 10. Further, the depths thereof are such that the upper portions of the guide pins 1 and the optical fibers 6 substantially coincide with the surface of the substrate 2. The lid 3 is adhered to the surface of the substrate 2 with the adhesive 8 via the guide pin 1 and the optical fiber 6. However, the guide pin 1 and the guide pin groove 4 and the guide pin fixing portion 5 are not attached to the adhesive. The material of the guide pin 1 is made of stainless steel, and the material of the substrate 2 and the lid 3 is made of a material such as ceramic, glass, or silicon which is hard, wear-resistant, and has good dimensional stability. Guide pin 1
Is not bonded to the guide pin groove 4 and the guide pin fixing portion because only the guide pin 1 may be replaced later. Note that the guide pin fixing portion 5 refers to a part of the lid 3 that is in contact with the guide pin 1. The optical fiber fixing section 9
Means a part of the lid 3 on the optical fiber 6.

得ない。By inserting the guide pin 1 into the guide pin groove of the female board type optical connector having the same configuration as described above except that there is no guide pin, The end faces of the optical fiber 6 are butted against each other. That is, the connection of the optical fiber 6 is made. In this case, it is ideal that a plurality of optical fibers be connected to each other at will. However, a slight displacement occurs due to the accuracy of machining or the like, and it is inevitable that the connection efficiency deteriorates.

なり、接続の再現性が期待できない。In the substrate type optical connector described above, the accuracy of the outer diameter of the guide pin and the dimensional accuracy of the V-shaped guide pin groove greatly affect the connection efficiency of the optical fiber. That is, as shown in FIG. 6, when the upper portion of the guide pin 1 protrudes above the surface of the substrate 2, a gap is formed between the upper portion of the optical fiber 6 and the optical fiber fixing portion 9. The rattling of the fiber 6 increases, and the positional relationship between the optical fibers cannot be kept constant. Therefore, loss fluctuation of the connection of the optical fiber becomes large, and reproducibility of the connection cannot be expected. On the other hand, when the upper portion of the guide pin 1 is lower than the surface of the substrate 2, the rattling of the optical fiber 6 is minimized, but the rattling of the guide pin 1 becomes large, so that the connection of the optical fiber is performed in the same manner as described above. Loss fluctuation becomes large, and reproducibility of connection cannot be expected.

It can be deformed at right angles.
Therefore, even if the guide pins protrude above the surface of the substrate or are recessed downward, the pressing force is applied from above the guide pin fixing portion or the optical fiber fixing portion to thereby fix the guide pin fixing portion. Can simultaneously press the guide pins on the portions of the substrate having the optical fiber grooves, respectively, with the optical fiber fixing portion. Accordingly, a substrate-type optical connector in which rattling of the optical fiber is minimized can be obtained.

た。In the board-type optical connector configured as described above, when the guide pins 1 protrude above the surface of the board 2, in a normal state, the surface of the portion having the optical fiber groove 7 of the board 2 is Although there is a gap between the optical fiber fixing portion 9 of the lid 3 and the optical fiber 6, the optical fiber 6 will rattle.
At this time, the pressing force is applied from above the optical fiber fixing portion 9 of the lid 3 by turning the optical fiber fixing portion pressing bolt 13, so that the gap is eliminated and the rattling of the optical fiber 6 can be minimized. Guide pin 1
When is below the surface of the substrate 2, in a normal state, a gap is formed between the guide pin fixing portion 5 of the lid 3 and the guide pin 1, and the guide pin 1 is rattled.
At this time, by turning the guide pin fixing part pressing bolt 12, a pressing force is applied to the guide pin fixing part 5 of the lid 3, and the gap is eliminated, so that the rattling of the guide pin 1 can be eliminated. In any case, the thickness of the cutout groove 14 provided between the guide pin fixing portion 5 and the optical fiber fixing portion 9 of the lid 3 is 1/3 of the thickness of the optical fiber fixing portion 9. Therefore, since the guide pin fixing portion 5 can be largely displaced with respect to the optical fiber fixing portion 9, even if the upper portion of the guide pin 1 does not coincide with the surface of the substrate 2, the optical fibers of the guide pin 1 and the substrate 2 do not match. Both surfaces of the portion having the groove 7 were pressed by the lid 3 at the same time. That is, the rattling of the optical fiber 6 can be minimized, and the rattling of the guide pin 1 can be completely eliminated, and the fluctuation of the connection loss of the optical fiber has almost disappeared.

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 cutout groove 14 is obliquely inserted between the guide pin fixing portion 5 and the optical fiber fixing portion 9 of the lid 3 from above and below. It is provided in. Also in this case, the guide pin fixing portion 5 of the lid 3
Since the cutout groove 14 is provided between the optical fiber fixing portion 9 and the optical fiber fixing portion 9, the thickness of the portion is smaller than the thickness of the fiber fixing portion 9, so that the same effect as described above is exhibited. In the figure, since one end of the guide pin fixing portion 5 rests on one end of the substrate 2, it is difficult to displace the guide pin fixing portion 5 downward only with the cutout groove 14. Notch groove 15
Is provided so that the guide pin fixing portion 5 can be easily displaced downward, but is not an essential requirement of the present invention.

きる。As described above, in the board-type optical connector of the present invention, since the guide pin fixing portion is easily deformed in a direction perpendicular to the surface of the board, it is possible to minimize rattling of the optical fiber. When this optical connector is connected to another female optical connector and an optical fiber is connected,
Since rattling is hardly generated between the optical connector and the female optical connector due to external force, fluctuations in connection loss can be almost eliminated, and reproducibility of connection can be expected.
