この構成によると、光電変換装置１０は、光ファイバ心線１６の一端部を第１の形状に保持し、他端部を第２の形状に保持する。そのため、光電変換装置１０において、電気機器の内部設けられたコネクタ（レセプタクル）に第１コネクタ１１および第２コネクタ１２を接続した場合に光ファイバ心線１６が予期せぬ形状に曲がる可能性を低減することができる。したがって、光電変換装置１０は、その設置場所に関わらず光信号の損失を軽減することができる。   According to this configuration, the photoelectric conversion device 10 holds one end of the optical fiber core wire 16 in the first shape and holds the other end in the second shape. Therefore, in the photoelectric conversion device 10, when the first connector 11 and the second connector 12 are connected to a connector (receptacle) provided inside the electrical device, the possibility that the optical fiber core wire 16 is bent into an unexpected shape is reduced. can do. Therefore, the photoelectric conversion device 10 can reduce the loss of the optical signal regardless of the installation location.

ここで、光電変換装置１０は、光ファイバ心線１６のうちコネクタから引き出された部位を覆うブッシング（第１ブッシング１３、第２ブッシング１４）を備えることが好ましい。保持用部材は、ブッシングと被覆部材１５のコネクタ側の端部との間の光ファイバ心線１６を、予め定められた形状で保持させるために覆う。この構成によると、光電変換装置１０は、その設置場所に関わらず光信号の損失を軽減することができる。   Here, the photoelectric conversion device 10 preferably includes bushings (first bushing 13 and second bushing 14) that cover a portion of the optical fiber core wire 16 that is drawn from the connector. The holding member covers the optical fiber core wire 16 between the bushing and the end of the covering member 15 on the connector side in order to hold the optical fiber core wire 16 in a predetermined shape. According to this configuration, the photoelectric conversion device 10 can reduce the loss of the optical signal regardless of the installation location.

ここで、保持用部材は、熱可塑性樹脂または熱硬化性樹脂であることが好ましい。この構成によると、光電変換装置１０は、光ファイバ心線１６を予め定められた形状に保つことができる。   Here, the holding member is preferably a thermoplastic resin or a thermosetting resin. According to this configuration, the photoelectric conversion device 10 can keep the optical fiber core wire 16 in a predetermined shape.

（実施形態２）
実施形態１では、第１保持用部材２０および第２保持用部材２１は単層としたが、本実施形態では、２層で形成されている。 (Embodiment 2)
In the first embodiment, the first holding member 20 and the second holding member 21 are single layers. However, in the present embodiment, the first holding member 20 and the second holding member 21 are formed of two layers.

以下、実施形態１との相違点を中心に説明する。なお、本実施形態では、実施形態１と同様の構成要素には同一の符号を付して説明を適宜省略する。   Hereinafter, the difference from the first embodiment will be mainly described. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

図４Ａは、本実施形態の光電変換装置１０の両端部を表す図であり、図４Ｂは、図４ＡにおけるＸ−Ｘの断面図である。なお、図４Ｂでは、第１コネクタ１１の記載を省略している。   4A is a diagram illustrating both end portions of the photoelectric conversion device 10 of the present embodiment, and FIG. 4B is a cross-sectional view taken along line XX in FIG. 4A. In FIG. 4B, the description of the first connector 11 is omitted.

本実施形態では、図４Ｂで示すように、第１保持用部材２０は、第１の層２０ａと第２の層２０ｂとの２層構造で形成され、第２保持用部材２１は、第１の層２１ａと第２の層２１ｂとの２層構造で形成されている。第２の層２０ｂ（２１ｂ）は、コア１６ｃとコア１６ｃの外周を包囲するクラッド１６ｄとから構成された光ファイバ心線１６の外周を包囲している。第１の層２０ａ（２１ａ）は、第２の層２０ｂ（２１ｂ）の外周を包囲している。つまり第２の層２０ｂ（２１ｂ）は、２層構造のうち内層に相当し、第１の層２０ａ（２１ａ）は、２層構造のうち外層に相当している。   In the present embodiment, as shown in FIG. 4B, the first holding member 20 is formed in a two-layer structure of a first layer 20a and a second layer 20b, and the second holding member 21 is a first layer. The layer 21a and the second layer 21b are formed in a two-layer structure. The second layer 20b (21b) surrounds the outer periphery of the optical fiber core wire 16 composed of the core 16c and the clad 16d surrounding the outer periphery of the core 16c. The first layer 20a (21a) surrounds the outer periphery of the second layer 20b (21b). That is, the second layer 20b (21b) corresponds to the inner layer of the two-layer structure, and the first layer 20a (21a) corresponds to the outer layer of the two-layer structure.

第１の層２０ａ（２１ａ）および第２の層２０ｂ（２１ｂ）の材質は、実施形態１で述べたように、ポリオレフィン、ポリ塩化ビニル、エラストマ等の熱可塑性樹脂である。ただし、第１の層２０ａ（２１ａ）と第２の層２０ｂ（２１ｂ）とは、硬度が異なっており、第１の層２０ａ（２１ａ）は第２の層２０ｂ（２１ｂ）よりも硬い材質で形成されている。   As described in Embodiment 1, the material of the first layer 20a (21a) and the second layer 20b (21b) is a thermoplastic resin such as polyolefin, polyvinyl chloride, or elastomer. However, the first layer 20a (21a) and the second layer 20b (21b) are different in hardness, and the first layer 20a (21a) is made of a material harder than the second layer 20b (21b). Is formed.

なお、本実施形態では、第１保持用部材２０および第２保持用部材２１は２層で形成されているとしたが、これに限定されない。第１保持用部材２０および第２保持用部材２１は３層以上から形成されてもよい。この場合、第１保持用部材２０および第２保持用部材２１における３つ以上の層の硬度は、最も外側の層から内側に向かうにつれて順次低下する。   In the present embodiment, the first holding member 20 and the second holding member 21 are formed of two layers, but the present invention is not limited to this. The first holding member 20 and the second holding member 21 may be formed of three or more layers. In this case, the hardness of the three or more layers in the first holding member 20 and the second holding member 21 sequentially decreases from the outermost layer toward the inside.

また、本実施形態においても第１保持用部材２０および第２保持用部材２１の材質は、熱硬化性樹脂であってもよい。この場合、第１の層２０ａ（２１ａ）は、第２の層２０ｂ（２１ｂ）よりも硬い材質で形成される。ここで、熱硬化性樹脂は、エポキシ樹脂、フェノール樹脂、メラミン樹脂等である。   Also in this embodiment, the material of the first holding member 20 and the second holding member 21 may be a thermosetting resin. In this case, the first layer 20a (21a) is formed of a material harder than the second layer 20b (21b). Here, the thermosetting resin is an epoxy resin, a phenol resin, a melamine resin, or the like.

なお、本実施形態では、第１の層２０ａ（２１ａ）および第２の層２０ｂ（２１ｂ）の双方とも熱可塑性樹脂、または熱硬化性樹脂であるとしたが、これに限定されない。例えば、内側の層である第１の層２０ａ（２１ａ）を熱可塑性樹脂、熱硬化性樹脂または接着剤で形成させて光ファイバ心線１６を所定の形状で保持させ、外側の層である第２の層２０ｂ（２１ｂ）を保護性が高く、かつ第１の層２０ａ（２１ａ）の硬度とは異なる硬度の材質で形成してもよい。   In the present embodiment, both the first layer 20a (21a) and the second layer 20b (21b) are made of a thermoplastic resin or a thermosetting resin. However, the present invention is not limited to this. For example, the first layer 20a (21a) that is the inner layer is formed of a thermoplastic resin, a thermosetting resin, or an adhesive to hold the optical fiber core wire 16 in a predetermined shape, and the first layer 20a (21a) that is the outer layer. The second layer 20b (21b) may be formed of a material having high protection and a hardness different from that of the first layer 20a (21a).

以上説明したように、保持用部材（第１保持用部材２０、第２保持用部材２１）は、互いに硬度が異なる少なくとも２つの層（第１の層２０ａ，２１ａ、第２の層２０ｂ，２１ｂ）からなることが好ましい。この構成によると、保持用部材を曲げる際に、光ファイバ心線１６が屈曲する可能性を低減することができる。   As described above, the holding members (the first holding member 20 and the second holding member 21) have at least two layers (the first layers 20a and 21a and the second layers 20b and 21b) having different hardnesses. ). According to this configuration, when the holding member is bent, the possibility that the optical fiber core wire 16 is bent can be reduced.

ここで、少なくとも２つの層の硬度は、最も外側の層から順次低下することが好ましい。この構成によると、単層の場合よりも光ファイバ心線１６に応力をかけることなく保持用部材を曲げること、つまり光ファイバ心線１６が屈曲する可能性を低減することができる。さらには、外部からの応力、部品等のエッジ等に対しても強くなる。   Here, it is preferable that the hardness of at least two layers sequentially decreases from the outermost layer. According to this configuration, it is possible to reduce the possibility that the holding member is bent without applying stress to the optical fiber core wire 16, that is, the possibility that the optical fiber core wire 16 bends, as compared with the case of a single layer. Furthermore, it becomes strong against external stress, edges of parts, and the like.

本実施形態では、実施形態１と比較して第１ブッシング１３および第２ブッシング１４の形状が異なる。さらに、第１保持用部材２０と光ファイバ心線１６との結合方法、および第２保持用部材２１と光ファイバ心線１６との結合方法が、実施形態１とは異なる。 (Embodiment 3)
