Yes. However, it is not necessary to limit to this position.
- the guide pins 121 and the guide holes 131 may be arranged at positions shifted from the optical components 110 and 120 in the Y direction, or may be at other positions. If at least two guide pins 121 and guide holes 131 are provided, the degree of freedom in the X direction and the Y direction of the second connector 102 can be limited, so the positions of the guide pins 121 and the guide holes 131 may be determined freely.

It is set to the same level as the total thickness (thickness). With such dimensions, the length of the shutter in the X direction can be shortened, so that the distance between the daughter boards 30 inserted into the backplane 20 can be narrowed. However, it is not necessary to limit to this length, and there is no disadvantage even if the length of the shutter 140 in the X direction is increased if there are other factors that require the spacing between the daughter boards 30 to be increased. .
- the “degree” is used to mean that an error in manufacturing or the like is allowed.
- the pressing portion 126 protrudes closer to the first connector 101 than the second light input / output portion 1201 by about the length of the shutter 140 in the X direction. Therefore, even if the portion of the shutter 140 covering the first light input / output unit 1101 rotates, the length of the second connector in the Z direction is set so that the shutter 140 does not hit the second light input / output unit 1201. It is shortened.
- the guide pin 121 protrudes closer to the first connector 101 than the second light input / output unit 1201 as much as the pressing portion 126.

Protrudes to the side. Therefore, it is not necessary to increase the size of the second connector in the Z direction for the guide pins 121, and the shutter 140 is rotated after limiting the degree of freedom of the second connector 102 in the X and Y directions. Can do.

- FIG. 3C is a diagram illustrating a state where the shutter 140 is rotated by being pressed by the pressing portion 126.
- the dirt 999 on the inner periphery of the guide hole 131 is peeled off by the guide pins 121 and scattered. However, only the inside of the guide hole 131 is scattered. As can be seen from FIG. 3C, dirt 999 also adheres to the outer surface of the shutter 140. The dirt 999 is peeled off and scattered by the pressing portion 126. However, the stain 999 is not scattered in the direction of the path of the second light input / output unit 1201. Further, since the pressing portion 126 does not come into contact with any part of the first connector 101 until it comes into contact with the shutter 140 in the process of inserting the daughter board 30, dirt other than the dirt of the shutter 140 is not scattered. Therefore, according to the optical connector for a backplane of the present invention, there is no risk that the first optical input / output unit 1101 and the second optical input / output unit 1201 are contaminated.

- the floating mechanism of the second connector 102 includes a rod 162, a flange 163, and a hole 166.
- the hole 166 is an oval hole whose Y direction is longer than the Z direction.
- the rod 162 is a circular rod having a diameter slightly shorter than the length of the hole 166 in the Z direction, and penetrates the hole 166. The difference between the diameter of the rod 162 and the length of the hole 166 in the Z direction may be within a range of manufacturing errors.
- the difference between the diameter of the rod 162 and the length of the hole 166 in the Y direction is the degree of freedom in the Y direction of the second connector 102 (the length that can float in the Y direction).
- the flange 163 is attached to the rod 162 so that the interval is wider than the length of the hole 166 in the X direction.
- the difference between the gap between the flanges 163 and the length of the hole in the X direction is the degree of freedom in the X direction of the second connector 102 (the length that can float in the X direction).
- the second connector 102 can be attached to the daughter board 30 so as to have a degree of freedom in the X direction and the Y direction. Note that the degrees of freedom in the X direction and the Y direction may be appropriately determined in consideration of manufacturing and assembly errors of the backplane 20 and the daughter board 30.

図3A~図3Cは、本発明のバックプレーン用光コネクタ100が課題を解決していることを説明するための図である。図3A~図3Cでは、説明に関係する部分には汚れ999を示している。なお、説明に関係ないので図示していないが、第1コネクタ101の外周部分には同じように汚れが付着している。図3Aは、第2コネクタ102が第1コネクタ101に接触する前の状態を示す図である。図3Bは、ガイドピン121がガイド穴131に挿入された状態を示す図である。図3Cは、シャッタ140が押圧部126に押されて回転した状態を示す図である。
図4は、本発明のバックプレーン用光コネクタの具体例を示す斜視図である。第1コネクタ101は、光部品110-1と、2つのガイド穴131を有するガイド部130と、シャッタ140と、回転軸150を備えている。この図では見えないが、光部品110-1は光部品固定部190-1に固定されており、光部品110-1の第1光入出力部1101はシャッタ140によって覆われている。第2コネクタ102は、2つのガイドピン121と、押圧部126と、光部品固定部170-1,…,4と、光部品120-1と、棒162と、ツバ163と、穴166を備える。この例では、光部品固定部170-2,3,4には光部品は固定されていない。また、第1コネクタ101は、光部品固定部170-2,3,4に対向する部分に、光部品固定部190-2,3,4も備えている(見えない部分なので図示されていない)。なお、図4の具体例では、ガイドピン121とガイド穴131は、光部品110-1,120-1とは、Y方向(ドーターボードの面と平行な方向)にずれた位置に配置されている。
