Description

本発明は、ラックに段積みされたスプライスユニットに後から簡単に光ケーブルを追加して引き込むことができるスプライスユニットに関するものである。   The present invention relates to a splice unit in which an optical cable can be easily added later and pulled into a splice unit stacked in a rack.

従来から、ラックに段積みされるスプライスユニットとして、後方から内部に光ケーブルを引き入れた後、内部で余長を取り、また後方へ引き出したり前方へアダプタ接続するものがある（例えば、特許文献１参照）。このような光ケーブルを接続するスプライスユニットには、図１０および図１１に示されるように、光ケーブルを固定するためのケーブルクランプ３５とテンションメンバクランプ３６を備えたケーブル把持部３４が設けられており、このケーブル把持部３４はユニット本体内に固定されているのが普通である。また、ユニット本体３１は上面が開放されたボックス形状であるため、上面の開放部を利用して光ケーブルをケーブルクランプ３５とテンションメンバクランプ３６に固定して配線していた。なお、図において３７は融着トレー、３８はケーブルガイドである。   2. Description of the Related Art Conventionally, as a splice unit stacked in a rack, there is one in which an optical cable is drawn from the rear to the inside, and then an extra length is taken inside, and the rear is pulled out or adapter connected to the front (for example, see Patent Document 1). ). As shown in FIGS. 10 and 11, the splice unit for connecting such an optical cable is provided with a cable gripping portion 34 including a cable clamp 35 and a tension member clamp 36 for fixing the optical cable. The cable gripping portion 34 is usually fixed in the unit main body. Further, since the unit main body 31 has a box shape with the upper surface opened, the optical cable is fixed and wired to the cable clamp 35 and the tension member clamp 36 using the open portion of the upper surface. In the figure, 37 is a fusing tray and 38 is a cable guide.

しかしながら、上記のようなものでは、ラックに段積みされた場合、上面の開放部が塞がれてしまうために、光ケーブルを後方側からケーブルクランプ３５とテンションメンバクランプケーブル３６に固定することができず、新たに別のユニットをラックに取付けることにより光ケーブルを増設する必要があった。   However, in the above-described case, when stacked in a rack, the open portion of the upper surface is blocked, so that the optical cable can be fixed to the cable clamp 35 and the tension member clamp cable 36 from the rear side. First, it was necessary to add an optical cable by attaching another unit to the rack.

一方、ユニット本体３１は、ラックに装着される固定部３２と前方側へスライドして引き出し自在な引き出し部３３とからなり、該引き出し部３３の中央部に融着トレー３７が設けられているのが普通である。このため、光コードの余長スペースを確保するにはユニット本体３１全体を大きくせねばならならないという問題点や、光コードの余長を収納できる本数が限られて施工性に劣るという問題点もあった。
特開２０００−２７５４４７号公報 On the other hand, the unit main body 31 includes a fixed portion 32 attached to the rack and a drawer portion 33 that can be slid forward and pulled out, and a fusion tray 37 is provided at the center of the drawer portion 33. Is normal. For this reason, in order to secure the extra length space of the optical cord, there is a problem that the entire unit body 31 has to be enlarged, and there is a problem that the number of optical cords that can accommodate the extra length is limited and the workability is inferior. there were.
JP 2000-275447 A

本発明は上記した従来の問題点を解決して、ラックに段積みされたスプライスユニットに後から簡単に光ケーブルを追加して引き込むことができ、またユニット本体を小型化しても十分な光ケーブルの余長スペースを確保することができるスプライスユニットを提供するためになされたものである。   The present invention solves the above-mentioned conventional problems, and can easily add an optical cable later to a splice unit stacked in a rack and pull it in, and even if the unit body is reduced in size, a sufficient amount of optical cable is sufficient. The present invention was made to provide a splice unit that can secure a long space.

上記の課題を解決するためになされた本発明のスプライスユニットは、ラックに段積みされるスプライスユニットであって、ユニット本体に、光ケーブルを固定するためのケーブルクランプとテンションメンバクランプを備えたケーブル把持部を引き出し自在に設けたことを特徴とするものである。   The splice unit of the present invention made to solve the above problems is a splice unit that is stacked in a rack, and includes a cable gripping unit that includes a cable clamp and a tension member clamp for fixing an optical cable to the unit body. This is characterized in that the part is provided so as to be freely drawn out.

また、ユニット本体は、ラックに装着される固定部と前方側へスライドして引き出し自在な引き出し部とからなり、該引き出し部の後方部には固定部の後方側に設けたケーブル把持部と干渉しないように床上げされた段上部が形成されているとともに、この段上部上に融着トレーが設けられているものとすることや、固定部と引き出し部との間にはケーブルガイドが設けられており、該ケーブルガイドが段上部の下面に収納可能とされているものとすることもできる。   In addition, the unit main body is composed of a fixed part mounted on the rack and a drawer part that is slidable forward and can be pulled out. The rear part of the drawer part interferes with the cable gripping part provided on the rear side of the fixed part. The floor is raised so that it does not rise, and a fusing tray is provided on the top, and a cable guide is provided between the fixed part and the drawer. The cable guide can be stored on the lower surface of the upper part of the step.

本発明では、ユニット本体に、光ケーブルを固定するためのケーブルクランプとテンションメンバクランプを備えたケーブル把持部を引き出し自在に設けたものとしたので、スプライスユニットをラックに段積みした場合でも、ケーブル把持部を後方側へ引き出すことにより簡単に光ケーブルを増設できることとなる。また、別の新たなスプライスユニットをラックに取付けなくても、光ケーブルを増設できることとなる。
更に、引き出し部の後方部に床上げされた段上部を形成して、この段上部上に融着トレーを設けた場合は、光コードの余長スペースが大きくなり余長を多くとれるとともに、多心数の光コードにも対応することができることとなる。 In the present invention, the cable gripping part including the cable clamp and the tension member clamp for fixing the optical cable is provided in the unit main body so that the cable gripping part can be pulled out, so that the cable gripping can be performed even when the splice unit is stacked in the rack. The optical cable can be easily added by pulling out the part to the rear side. In addition, an optical cable can be added without attaching another new splice unit to the rack.
Further, when a raised upper part is formed at the rear part of the drawer part and a fusion tray is provided on the upper part, the extra length of the optical cord becomes larger and the extra length can be increased. It is possible to cope with a number of optical codes.

以下に本発明を図面とともに詳細に説明する。   The present invention will be described in detail below with reference to the drawings.

図１は本発明のスプライスユニットであってケーブル把持部を後方へ引き出した状態を示す斜視図、図２は同様の融着トレー７及び後述する段上部を略した場合を示す斜視図である。また、図３は本発明のスプライスユニットをラック１１に段積みした状態を示す正面図、図４はその側面図、図５はその斜視図、図６は要部の拡大斜視図である。図７は、引き出し部３を引き出した状態を示す側面図、図８はその斜視図、図９は収納状態を示す斜視図である。図において、１はユニット本体であり、図示のものでは、ユニット本体１はラックに装着される固定部２と前方側へスライドして引き出し自在な引き出し部３とから構成されている。なお、図中、８は余長収納部、１２は光ケーブルである。   FIG. 1 is a perspective view showing a state in which a cable gripping portion is pulled out rearward in the splice unit of the present invention, and FIG. 2 is a perspective view showing a case where a similar fusion tray 7 and a stepped portion described later are omitted. 3 is a front view showing a state in which the splice units of the present invention are stacked on the rack 11, FIG. 4 is a side view thereof, FIG. 5 is a perspective view thereof, and FIG. 7 is a side view showing a state in which the drawer portion 3 is pulled out, FIG. 8 is a perspective view thereof, and FIG. 9 is a perspective view showing a stored state. In the figure, reference numeral 1 denotes a unit main body. In the illustrated case, the unit main body 1 is composed of a fixed portion 2 mounted on a rack and a drawer portion 3 that can slide forward and be pulled out. In the figure, 8 is a surplus length storage section and 12 is an optical cable.

そして本発明では、ユニット本体１の後部に、光ケーブル１２を固定するためのケーブルクランプ５とテンションメンバクランプ６を備えたケーブル把持部４を後方側へ引き出し自在に設けたものとなっている。
このように、ケーブル把持部４が必要に応じて任意に後方側へ引き出し可能な構造となっているので、スプライスユニットをラック１１に段積みして、上面の開放部が塞がった状態となっても、ケーブル把持部４を後方側へ引き出すことでケーブルクランプ５とテンションメンバクランプ６を外部へ露出させ、簡単に光ケーブル１２を固定・増設できることとなる。また、光ケーブル１２を増設後はケーブル把持部４を前方側へ戻せばユニット本体１内に再び収納されるので邪魔になることもない。従って、従来のように別の新たなスプライスユニットをラックに取付けなくても、光ケーブル１２を簡単に増設できることとなる。なお、ケーブル把持部４は後方側へ引き出すもので説明したが、ユニット本体１の固定部２の側面の孔を利用して横方向に引き出せるようにしてもよい。 In the present invention, the cable gripping portion 4 including the cable clamp 5 for fixing the optical cable 12 and the tension member clamp 6 is provided at the rear portion of the unit main body 1 so as to be freely drawn out to the rear side.
Thus, since the cable gripping portion 4 has a structure that can be arbitrarily pulled out to the rear side as necessary, the splice units are stacked on the rack 11 and the open portion on the upper surface is closed. However, the cable clamp 5 and the tension member clamp 6 are exposed to the outside by pulling out the cable gripping portion 4 to the rear side, and the optical cable 12 can be easily fixed and added. Further, after the optical cable 12 is added, if the cable gripping portion 4 is returned to the front side, it is housed again in the unit main body 1 so that it does not get in the way. Therefore, the optical cable 12 can be easily added without attaching another new splice unit to the rack as in the prior art. The cable gripping portion 4 has been described as being pulled out to the rear side. However, the cable gripping portion 4 may be pulled out in the lateral direction using a hole in the side surface of the fixing portion 2 of the unit body 1.

図７に示すように、ユニット本体１は、ラック１１に装着される固定部２と前方側へスライドして引き出し自在な引き出し部３とからなり、該引き出し部３の後方部には固定部２の後方側に設けたケーブル把持部４と干渉しないように床上げされた段上部９が形成されているとともに、この段上部９上に融着トレー７が設けられたものとなっている。     As shown in FIG. 7, the unit main body 1 includes a fixed portion 2 mounted on the rack 11 and a drawer portion 3 that can be slid forward and pulled out. A stepped upper portion 9 is formed so that it does not interfere with the cable gripping portion 4 provided on the rear side, and a fusion tray 7 is provided on the stepped upper portion 9.

すなわち、従来は融着トレー７が引き出し部３の中央部に設けられていたので、光コードの余長スペースを確保するにはユニット本体全体を大きくせねばならならないという問題点や、光コードの余長を収納できる本数が限られるという問題点があったのに対し（図１０、図１１参照）、図７のものでは引き出し部３の後方部に固定部２の後方側に設けたケーブル把持部４と干渉しないように床上げされた段上部９が形成されており、この段上部９上に融着トレー７を設けたものとなっている。つまり、本発明では融着トレー７を床上げされた段上部９上に設置することで引き出し部３の中央部に空白スペースを確保し、このスペースに余長収納部８を形成して余長コードを収納させることでコンパクトなユニット構造を達成するのである。   That is, conventionally, the fusion tray 7 has been provided at the center of the drawer 3, so that it is necessary to enlarge the entire unit body in order to secure the extra space for the optical cord, While there was a problem that the number of extra lengths that could be stored was limited (see FIGS. 10 and 11), in the case of FIG. 7, the cable grip provided on the rear side of the fixed portion 2 on the rear portion of the drawer portion 3 A stepped upper portion 9 is formed so as not to interfere with the portion 4, and a fusion tray 7 is provided on the stepped upper portion 9. In other words, according to the present invention, by installing the fusion tray 7 on the raised stepped portion 9, a blank space is secured in the center portion of the drawer portion 3, and the extra length storage portion 8 is formed in this space to form the extra length code. A compact unit structure is achieved by storing the container.

なお、固定部２と引き出し部３との間にケーブルガイド１０（一点鎖線で表示）が設けられており、該ケーブルガイド１０を段上部９の下面に収納可能とすることもでき、この場合は、ケーブルガイド１０が段上部９の下面にスッポリと完全に収納されるためコードの余長スペース確保のためにユニット自体を大きくする必要がなくなり、コンパクトなユニット構造が可能となる。   In addition, a cable guide 10 (indicated by a one-dot chain line) is provided between the fixed portion 2 and the drawer portion 3, and the cable guide 10 can be stored on the lower surface of the stepped portion 9. In this case, Since the cable guide 10 is completely accommodated in the lower surface of the stepped portion 9, it is not necessary to enlarge the unit itself in order to secure the extra space for the cord, and a compact unit structure is possible.

このように、本発明ではユニット本体１に、光ケーブル１２を固定するためのケーブルクランプ５とテンションメンバクランプ６を備えたケーブル把持部４を引き出し自在に設けたものとなっているので、ケーブル把持部４を引き出してケーブルクランプ５とテンションメンバクランプ６を外部へ露出させれば、簡単に光ケーブル１２を固定・増設できることとなる。
また、該引き出し部３の後方部に固定部２の後方側に設けたケーブル把持部４と干渉しないように床上げされた段上部９が形成されているとともに、この段上部９上に融着トレー７が設けられたものとすれば、引き出し部３の中央部に空白スペースを確保し、このスペースに余長収納部８を形成して余長コードを収納させることが可能となり、更には、ケーブルガイド１０を段上部９の下面に収納すればよりコンパクトなユニット構造が提供できることとなる。 As described above, in the present invention, the cable gripping portion 4 including the cable clamp 5 and the tension member clamp 6 for fixing the optical cable 12 is provided in the unit main body 1 so as to be freely drawn out. If the cable clamp 5 and the tension member clamp 6 are exposed to the outside by pulling out 4, the optical cable 12 can be easily fixed and added.
Further, a stepped upper portion 9 is formed on the rear portion of the drawer portion 3 so as not to interfere with the cable gripping portion 4 provided on the rear side of the fixed portion 2, and a fusion tray is formed on the stepped upper portion 9. 7 is provided, it is possible to secure a blank space in the central portion of the drawer portion 3, and to form a surplus length storage portion 8 in this space to store the surplus length cord. If the guide 10 is stored in the lower surface of the stepped portion 9, a more compact unit structure can be provided.
