ところが、従来の光ファイバ収容部を備えた光受信機によると、光ファイバ収容部に光ケーブルを配設するための挿入口の位置が予め決められていることにより、前記光受信機を通常の如く壁面等の設置面に装着する場合、光ケーブルの配線方向に制限が生じるなど、光ケーブルの配線の容易性、つまりは設置工事の容易性が損なわれる点で問題があった。 However, according to the conventional optical receiver provided with the optical fiber housing portion, the position of the insertion port for arranging the optical cable in the optical fiber housing portion is determined in advance, so that the optical receiver is operated as usual. When it is mounted on an installation surface such as a wall surface, there is a problem in that the ease of optical cable wiring, that is, the ease of installation work is impaired, such as restrictions on the wiring direction of the optical cable.

また、光受信機の近傍まで壁面等に沿うように配線されてきた光ケーブルを当該光受信機に引き込むため、壁面に引き回された光ケーブルと前記光受信機との間に配設される光ケーブルの自由部分に対して、前記光ケーブルの曲げ半径が当該光ケーブルの安全曲率を超えないようにするには、光ケーブルが配線されている方向（例えば、光受信機の上方から光ケーブルが配線されている場合）に応じて、当該光ケーブルが破損しないよう曲率を考えながら、大きく弧を描くように撓ませるなどして配線する必要が生じ、配線に時間が掛かったり、余分な長さの光ファイバが必要となると言った問題もあった。
Also, in order to draw the optical cable that has been routed along the wall surface up to the vicinity of the optical receiver into the optical receiver, an optical cable disposed between the optical receiver and the optical cable routed on the wall surface. To prevent the bending radius of the optical cable from exceeding the safety curvature of the optical cable with respect to the free part, the direction in which the optical cable is wired (for example, when the optical cable is wired from above the optical receiver) Depending on the situation, it is necessary to wire the cable by bending it so as to draw a large arc while considering the curvature so that the optical cable is not damaged, and the wiring takes time or an extra length of optical fiber is required. There was also the problem I said.

更に言えば、上述のように配線した結果、壁面に引き回された光ケーブルと前記光受信機との間に配設する光ケーブルの自由部分が長すぎてしまうことになって、作業をする際に作業道具を光ケーブルに引っ掛けたり、余分なストレスが加わったりする可能性が大きくなり、光ケーブルを破損させてしまうと言った問題も考えられた。
Furthermore, as a result of wiring as described above, the free portion of the optical cable disposed between the optical cable routed on the wall surface and the optical receiver will be too long, and when working The possibility of hooking the work tool on the optical cable and applying extra stress increased, and there was a problem that the optical cable was damaged.

そこで本願においては、こうした問題点を解決するためになされたものであり、
その目的は、設置工事の容易な光受信機を提供することに有る。
その目的は、余長の光ケーブルの収納が容易な光ファイバ収容部を備えた光受信機を提供することに有る。
他の目的は、光ケーブルにストレスが加わったり、破損したりすることの無い光受信機を提供することにある。
Therefore, in the present application, it was made to solve these problems,
The purpose is to provide an optical receiver that is easy to install.
An object of the present invention is to provide an optical receiver including an optical fiber accommodating portion that can easily accommodate an extra-length optical cable.
Another object is to provide an optical receiver which does not cause stress or damage to the optical cable.

A procedure for disposing the optical fiber 33 in the optical receiver 1 configured as described above will be described with reference to FIG. 4 is a perspective view for explaining a state in which the optical fiber 33 is disposed in the optical receiver 1 of the present invention. FIG. 4A is an enlarged view showing a connection portion between the optical relay adapter 31 and the optical connector 32. FIG. (B) is an enlarged view showing the optical fiber housing 8. As shown in FIG. 4, the optical connector 32 provided at the end of the optical fiber 33 is exposed from the terminal portion 18 in the storage space 15, and the light provided in the optical receiver 30. Begin by attaching to the relay adapter 31. When the mounting is completed, the optical fiber 33 drawn out from the optical connector 32 is moved from the outside of the case body 2 (specifically, the outer surface 2c) to the direction of the arrow in FIG. When inserted, the optical fiber 33 is disposed from the arrangement path 13 to the storage space 15 and the side of the optical fiber storage portion 8 located on the opposite side of the storage space 15 (from point A in FIG. 4A). It is arranged at point B in FIG.

ここで、前記光ファイバ収容部８側に配設された余長の前記光ファイバ３３を、当該光ファイバ収容部に設けられた巻枠５に巻き付けるに当たり、前記光コネクタ３２と光ファイバ収容部８との間の光ケーブル３３が緩んだ状態とならないよう、光ファイバ３３を引っ張ったとしても、当該光ファイバ３３は、前記収容空間１５に形成された前記添付壁１２と、前記配設路１３を構成する前記内周壁１３ｂ及び底壁１３ａに添付されるので、前記光ファイバ３３は安全曲率の範囲内で配設される。
Here, when the extra length of the optical fiber 33 disposed on the optical fiber housing portion 8 is wound around the winding frame 5 provided in the optical fiber housing portion, the optical connector 32 and the optical fiber housing portion 8 are wound. Even if the optical fiber 33 is pulled so that the optical cable 33 between them is not loosened, the optical fiber 33 constitutes the attachment wall 12 formed in the accommodation space 15 and the arrangement path 13. Since it is attached to the inner peripheral wall 13b and the bottom wall 13a, the optical fiber 33 is disposed within a safe curvature range.

即ち、本考案の実施形態に係る光受信機１によれば、前記収容空間１５（詳しくは、光コネクタ３１と光受信部３０の光中継用コネクタ３１の接続部分である端子部１８）と、余長の光ファイバ３３を収容する前記光ファイバ収容部８とが同一面上にならないように構成されているので、光受信機１を小型化できる。また、端子部１８と前記光ファイバ収容部８との位置関係が前記収容空間１５の段部１１を介して反対側に位置するように構成されていても、前記切欠部７の存在によって、光ファイバ３３を前記収容空間１５と前記光ファイバ収容部８との間に容易に配設することができるから、光受信機１の設置工事をより簡単なものにすることができる。しかも、光ファイバ３３を前記収容空間１５と前記光ファイバ収容部８との間に配設する際は、前記光ファイバを安全曲率の範囲内で添付を可能とする前記添付壁１２と前記配設路１３の存在によって、光ファイバの最小曲げ半径を気にすることなく配設作業を行なうことができるので、設置工事の工数を低減するばかりでなく、工事の信頼性を向上させることができる。更に言えば、前記光コネクタ３２と当該光コネクタ３２から引き出された光ファイバ３３を前記収容空間１５内に収納して、前記光受信機１の外形より外側にはみ出さない構成すると共に、当該収納空間１５を蓋体３で持って閉塞するように構成したことによって、設置工事をする際に作業道具を光コネクタ３２や光ファイバ３３に引っ掛けたり、余分なストレスが加わったりする可能性を無くすことができ、この点でも設置工事を容易、且つ安全に行うことができる。
That is, according to the optical receiver 1 according to the embodiment of the present invention, the accommodation space 15 (specifically, the terminal portion 18 which is a connection portion between the optical connector 31 and the optical relay connector 31 of the optical receiver 30), and Since the optical fiber accommodating portion 8 that accommodates the extra length optical fiber 33 is configured not to be on the same plane, the optical receiver 1 can be reduced in size. Even if the positional relationship between the terminal portion 18 and the optical fiber housing portion 8 is positioned on the opposite side via the step portion 11 of the housing space 15, the presence of the notch portion 7 makes it possible to Since the fiber 33 can be easily disposed between the housing space 15 and the optical fiber housing portion 8, the installation work of the optical receiver 1 can be simplified. In addition, when the optical fiber 33 is disposed between the accommodating space 15 and the optical fiber accommodating portion 8, the attachment wall 12 and the arrangement which enable the optical fiber to be attached within the range of the safety curvature. The presence of the path 13 makes it possible to perform the installation work without worrying about the minimum bending radius of the optical fiber, so that not only the number of installation works can be reduced, but also the work reliability can be improved. More specifically, the optical connector 32 and the optical fiber 33 drawn out from the optical connector 32 are housed in the housing space 15 so as not to protrude outside the outer shape of the optical receiver 1 and the housing. By configuring the space 15 so as to be closed by the lid 3, it is possible to eliminate the possibility that a work tool may be hooked on the optical connector 32 or the optical fiber 33 or excessive stress may be applied during installation work. In this respect, the installation work can be performed easily and safely.
