Description

【0001】
【発明の属する技術分野】
本発明は、両端に光部品が接続された光ファイバを巻いた状態で収容する光ファイバの包装ケースに関するものである。
【0002】
【従来の技術】
図3に示すように、光ファイバ1の両端にパッケージ2や光コネクタ3等の光部品4が接続されてなる光モジュール5を収容するには、従来、光部品4を固定して収容する光部品収容部6と、光ファイバ1を収容する光ファイバ収容部7と、この光ファイバ収容部7内に設けられ光ファイバ1を巻き付ける巻付部8とが設けられた光ファイバ1の包装ケース9が用いられていた。
【0003】
この包装ケース9は、パッケージ2を光部品収容部6に固定して、光ファイバ1の長さに応じて光ファイバ1を巻付部8へ巻き付けた後に折り返して、光コネクタ3を光部品収容部6に固定するようになっている。すなわち、光ファイバ1の巻付部8への巻付回数を調整することで、光ファイバ1の長さと、光部品収容部6、光ファイバ収容部7及び巻付部8間の距離との関係を最適にするようになっていた。
【0004】
これによって、包装ケース9内で光ファイバ1を弛ませることなく収容でき、光ファイバ1を安定した状態で運搬するようになっていた。
【0005】
【特許文献1】
実開平5−55104号公報
【0006】
【発明が解決しようとする課題】
しかしながら、光モジュール5の光ファイバ1は、その長さが多種に及び、上述の包装ケース9では、光部品収容部6と巻付部8との距離が一定であるため、光ファイバ1の巻付部8への巻付回数だけでは、光ファイバ1の長さと、光部品収容部6、光ファイバ収容部7及び巻付部8間の距離との関係を最適とすることができない場合もあった。
【0007】
この場合、包装ケース9内で光ファイバ1が弛んだ状態となっているので、運搬時の振動により、光ファイバ1の巻付部8への巻き状態が崩れて、光ファイバ1の断線を引き起こすことがあるといった問題があった。
【0008】
そこで、本発明は上記問題を解決すべく案出されたものであり、その目的は、光ファイバの長さに拘わらず、安定した状態で運搬できる光ファイバの包装ケースを提供することにある。
【0009】
【課題を解決するための手段】
前記課題を解決すべく、本発明は、包装ケース本体に光ファイバの両端に接続された光部品を固定して収容する光部品収容部と、上記光ファイバを収容する光ファイバ収容部と、この光ファイバ収容部内に設けられ上記光ファイバを巻き付ける巻付部とを備えた光ファイバの包装ケースにおいて、上記巻付部と上記光部品収容部との距離を可変とすべく上記巻付部を複数の位置から取付位置を選択して上記包装ケース本体に取り付けたものである。
【0010】
そして、上記巻付部に突起部を設け、上記包装ケース本体に上記突起部が嵌合される穴を上記光部品収容部からの距離を代えて複数形成したものが好ましい。
【0011】
また、上記包装ケース本体が、導電性材料を混合した弾性素材にて形成されたものが好ましい。
【0012】
【発明の実施の形態】
以下、本発明の実施の形態を添付図面に従って説明する。
【0013】
図1及び図2に示すように、本実施の形態に係る光ファイバ1の包装ケース11は、光ファイバ1の両端にパッケージ2や光コネクタ3等の光部品4が接続されてなる光モジュール5を収容するものである。
【0014】
包装ケース11は、包装ケース本体12に光ファイバ1の両端に接続された光部品4を固定して収容する光部品収容部6と、光ファイバ1を収容する光ファイバ収容部7と、この光ファイバ収容部7内に設けられ光ファイバ1を巻き付ける巻付部19とを備えている。
【0015】
包装ケース本体12は、スポンジやウレタンフォーム等の弾性素材にて長方形の板状に形成されている。弾性素材には、静電気を防止するためにフェライトやカーボン等の導電性材料が混入されている。
【0016】
光部品収容部6は、パッケージ2用と光コネクタ3用の二箇所形成されており、包装ケース本体12の長手方向一端部側の短手方向両側近傍にそれぞれ配置されている。光部品収容部6は、包装ケース本体12の表面に所定深さの凹部15をそれぞれ形成して構成されている。凹部15は、パッケージ2及び光コネクタ3の厚さより深い深さを有しており、パッケージ2や光コネクタ3が包装ケース本体12の表面から突出しないようになっている。
【0017】
光ファイバ収容部7は、凹部15よりも浅い凹部16にて構成されている。凹部16は、光部品収容部6に連続して形成され一方の光部品収容部6から包装ケース本体12の長手方向逆側へ延出して、包装ケース本体12の端部近傍で折り返して、他方の光部品収容部6に連通しており、略U字状に形成されている。凹部16は、光ファイバ1が包装ケース本体12の表面から出ない幅及び深さで形成されており、光部品収容部6との間に段部17が形成されている。この段部17で、光部品収容部6に収容された光部品4が係止され固定されるようになっている。光ファイバ収容部7の折返部18は、光ファイバ1を巻くために幅広に形成されている。
【0018】
折返部18には、光ファイバ1を巻き付ける巻付部19が、包装ケース本体12の下側(図1中紙面裏側)から着脱自在に設けられている。巻付部19は、折返部18の内周面と所定の間隔を隔てる外周面を有する円柱部21と、円柱部21から径方向外方に延びるブラケット22とを備えている。
【0019】
折返部18には、円柱部21が包装ケース本体12の下側から挿入される長穴27が形成されている。長穴27は、包装ケース本体12の長手方向に長い形状となっている。ブラケット22は、円柱部21から包装ケース本体12の短手方向両側に延出して包装ケース本体12の両端から突出しない長さに形成されており、その先端部近傍には上方に延びる突起部23がそれぞれ設けられている。
【0020】
包装ケース本体12には、突起部23が選択的に嵌合する穴24、25、26が設けられている。穴24、25、26は、包装ケース本体12の短手方向両側近傍に、光部品収容部6からの距離を代えて複数(本実施の形態では3箇所ずつ)それぞれ形成されている。すなわち、穴24、25、26は、包装ケース本体12の長手方向に複数(3対)並列されている。
【0021】
収容される光ファイバ1の長さに応じて、最適な位置の穴24、25、26(本実施の形態では中央の25)が選択され、その穴25に突起部23が嵌合されて、これと同時に、円柱部21が長穴27から光ファイバ収容部6の折返部18内上方へと突出して、巻付部19が包装ケース本体12に装着される。このとき、円柱部21は、長穴27に挿入されるので、上記穴24、25、26のうちどれを選択しても、円柱部21が包装ケース本体12に干渉することはなく、折返部18内へ突出することができる。
【0022】
なお、包装ケース本体12の下面の、穴24、25、26の周辺には、巻付部19を装着した際にブラケット22が収容されるブラケット用凹部28が形成されており、ブラケット22が、包装ケース本体12の下面から突出しないようになっている。これによって、運搬時に、包装ケース11を平らに積み上げることができ、安定性を高めることができる。
【0023】
上記構成によれば、巻付部19の突起部23を嵌合する穴24、25、26を選択して巻付部19を装着することによって、光部品収容部6と巻付部19との距離を、光ファイバ1の長さに応じた最適な長さにすることができる。これによって、光ファイバ1を弛ませることなく安定した状態で、包装ケース11内に収容することができる。従って、運搬時の振動等の外力が包装ケース11にかかっても、光ファイバ1の巻付部19への巻き状態が崩れることはなく、光ファイバ1同士がずれることはないので、光ファイバ1の断線等の破損を確実に防止できる。
【0024】
また、包装ケース本体12を弾性素材にて形成したので、運搬中の振動や衝撃を吸収でき、包装ケース11内の光モジュール5へかかる振動等を低減できる。さらに、弾性素材に導電性材料を混合したので、包装ケース11内での静電気の発生を防止できる。従って、IC等の電子部品や光素子(半導体レーザや受光素子)から構成される光モジュール5の静電破壊を防止できる。
【0025】
なお、上記実施の形態では、穴24、25、26を3対としたがこれに限られるものではなく、2対或いは4対以上としてもよい。さらに、穴24、25、26は、包装ケース本体12の長手方向に沿って配置しているが、配置方向を、長手方向に対して傾斜させたり、複数の方向を組み合わせたりしてもよい。
【0026】
さらに、上記実施の形態では、巻付部19に突起部23を設け、包装ケース本体12に穴24、25、26を設けているが、それらの設置位置を逆にしてもよい。また、装着方法も凹凸の嵌め合いに限られるものではなく、接着や他の方法であってもよい。
【0027】
【発明の効果】
以上要するに本発明によれば、光ファイバの長さに拘わらず、光ファイバを安定した状態で運搬できるといった優れた効果を発揮する。

[0015]
The packaging case body 12 is formed in a rectangular plate shape with an elastic material such as sponge or urethane foam. The elastic material is mixed with a conductive material such as ferrite or carbon in order to prevent static electricity.
[0016]
The optical component housing portions 6 are formed at two locations for the package 2 and the optical connector 3, and are respectively disposed in the vicinity of both sides in the lateral direction on one end side in the longitudinal direction of the packaging case body 12. The optical component housing 6 is configured by forming recesses 15 having a predetermined depth on the surface of the packaging case body 12. The recess 15 has a depth deeper than the thickness of the package 2 and the optical connector 3 so that the package 2 and the optical connector 3 do not protrude from the surface of the packaging case body 12.
[0017]
The optical fiber housing portion 7 is configured by a recess 16 that is shallower than the recess 15. The concave portion 16 is formed continuously from the optical component housing portion 6 and extends from one optical component housing portion 6 to the opposite side in the longitudinal direction of the packaging case body 12, and is folded back in the vicinity of the end of the packaging case body 12. Are communicated with the optical component housing 6 and are formed in a substantially U-shape. The recess 16 is formed with a width and depth that prevent the optical fiber 1 from coming out of the surface of the packaging case body 12, and a stepped portion 17 is formed between the recess 16 and the optical component housing 6. At this stepped portion 17, the optical component 4 accommodated in the optical component accommodating portion 6 is locked and fixed. The folded portion 18 of the optical fiber housing portion 7 is formed wide so as to wind the optical fiber 1.
[0018]
A winding portion 19 around which the optical fiber 1 is wound is provided in the folding portion 18 so as to be detachable from the lower side of the packaging case body 12 (the back side of the paper surface in FIG. 1). The winding portion 19 includes a columnar portion 21 having an outer peripheral surface that is spaced apart from the inner peripheral surface of the folded portion 18 and a bracket 22 that extends radially outward from the columnar portion 21.
[0019]
An elongated hole 27 into which the cylindrical portion 21 is inserted from the lower side of the packaging case main body 12 is formed in the folded portion 18. The long hole 27 has a shape that is long in the longitudinal direction of the packaging case body 12. The bracket 22 is formed to have a length that extends from the cylindrical portion 21 to both sides in the short direction of the packaging case main body 12 and does not protrude from both ends of the packaging case main body 12. Are provided.
[0020]
The packaging case main body 12 is provided with holes 24, 25, and 26 into which the protrusions 23 are selectively fitted. A plurality of holes 24, 25, and 26 are formed in the vicinity of both sides in the short direction of the packaging case main body 12 at different distances from the optical component housing portion 6 (three in this embodiment). That is, a plurality (three pairs) of holes 24, 25, and 26 are juxtaposed in the longitudinal direction of the packaging case body 12.
[0021]
Depending on the length of the optical fiber 1 to be accommodated, holes 24, 25, and 26 at the optimum positions (25 in the center in the present embodiment) are selected, and the projections 23 are fitted into the holes 25, At the same time, the cylindrical portion 21 protrudes upward in the folded portion 18 of the optical fiber housing portion 6 from the long hole 27, and the winding portion 19 is attached to the packaging case main body 12. At this time, since the cylindrical portion 21 is inserted into the long hole 27, the cylindrical portion 21 does not interfere with the packaging case body 12 regardless of which of the holes 24, 25, 26 is selected, and the folded portion 18 can protrude into.
[0022]
A bracket recess 28 is formed in the lower surface of the packaging case main body 12 and around the holes 24, 25, and 26 to receive the bracket 22 when the winding portion 19 is attached. It does not protrude from the lower surface of the packaging case body 12. Thereby, the packaging case 11 can be piled up flatly at the time of conveyance, and stability can be improved.
[0023]
According to the above configuration, by selecting the holes 24, 25, and 26 in which the protrusions 23 of the winding part 19 are fitted and attaching the winding part 19, the optical component housing part 6 and the winding part 19 The distance can be set to an optimum length according to the length of the optical fiber 1. Thereby, the optical fiber 1 can be accommodated in the packaging case 11 in a stable state without being loosened. Therefore, even when an external force such as vibration during transportation is applied to the packaging case 11, the winding state of the optical fiber 1 around the winding portion 19 is not broken, and the optical fibers 1 are not displaced from each other. Breakage such as disconnection can be reliably prevented.
[0024]
Moreover, since the packaging case main body 12 is formed of an elastic material, vibrations and impacts during transportation can be absorbed, and vibrations applied to the optical module 5 in the packaging case 11 can be reduced. Further, since the conductive material is mixed with the elastic material, the generation of static electricity in the packaging case 11 can be prevented. Therefore, it is possible to prevent electrostatic breakdown of the optical module 5 composed of electronic components such as ICs and optical elements (semiconductor lasers and light receiving elements).
[0025]
In the above embodiment, three pairs of holes 24, 25, and 26 are used. However, the present invention is not limited to this, and two pairs or four or more pairs may be used. Furthermore, although the holes 24, 25, and 26 are arranged along the longitudinal direction of the packaging case body 12, the arrangement direction may be inclined with respect to the longitudinal direction, or a plurality of directions may be combined.
[0026]
Furthermore, in the said embodiment, although the projection part 23 is provided in the winding part 19 and the holes 24, 25, and 26 are provided in the packaging case main body 12, those installation positions may be reversed. Also, the mounting method is not limited to the fitting of unevenness, and may be adhesion or other methods.
[0027]
【The invention's effect】
In short, according to the present invention, an excellent effect that the optical fiber can be transported in a stable state regardless of the length of the optical fiber is exhibited.
