JP 2001-194562 A

しかしながら、従来においては、ハウジングの複数の挿入部毎に個々のシャッター板を固定し、各シャッター板の立ち上がり部をそれぞれ独立した状態で挿入部内奥側に臨ませるようにしているため、部品点数が増えてコスト高となり、しかも、組み付け作業が非常に面倒なものとなる問題があった。   However, conventionally, each shutter plate is fixed to each of the plurality of insertion portions of the housing, and the rising portions of the shutter plates are faced to the back side in the insertion portion in an independent state. There is a problem that the cost is increased and the assembling work becomes very troublesome.

そこで、本発明は、叙上のような従来存した諸事情に鑑み案出されたもので、双方向からの光コネクタプラグを受け入れ可能となる両端開口の複数の挿入部を有するハウジングの各挿入部内に割りスリーブを介して挿入されるスリーブホルダーを備えて成る光コネクタ相互接続用アダプタにおいて、１点部品による遮光部材で複数の挿入部内の遮光が同時に行えることで、製造上における作業性の向上と低コスト化を図ることができる光コネクタ相互接続用アダプタを提供することを目的とする。   Therefore, the present invention has been devised in view of the conventional circumstances as described above, and each insertion of a housing having a plurality of insertion portions with both end openings capable of receiving a bidirectional optical connector plug. In an optical connector interconnection adapter comprising a sleeve holder inserted through a split sleeve in the part, light shielding in a plurality of insertion parts can be performed simultaneously with a light shielding member made of one point component, thereby improving workability in manufacturing. An object of the present invention is to provide an optical connector interconnection adapter capable of reducing the cost.

上述した課題を解決するため、本発明にあっては、双方向からの光コネクタプラグを受け入れ可能となる両端に複数の開口を有するハウジングの各開口内に割りスリーブを介して挿入されるスリーブホルダーを備えて成る光コネクタ相互接続用アダプタであって、ハウジングの開口側に着脱可能に係止される差し込み部と、各開口内奥側のスリーブホルダーからの出射光を同時に遮蔽するよう差し込み部に突設した複数の遮光板とから成る遮光部材を備えたことを特徴とする。   In order to solve the above-described problem, in the present invention, a sleeve holder inserted into each opening of a housing having a plurality of openings at both ends capable of receiving an optical connector plug from both directions via a split sleeve. An optical connector interconnection adapter comprising: an insertion portion that is detachably locked to the opening side of the housing; and an insertion portion that simultaneously shields light emitted from the sleeve holder inside each opening. A light-shielding member comprising a plurality of light-shielding plates protruding is provided.

遮光部材は、２つの開口を有するハウジングの両開口間に装着して係止される差し込み部と、両開口内奥側のスリーブホルダーからの出射光を同時に遮蔽するよう差し込み部から末広がりの二股状に突設した一対の遮光板とから成る。   The light shielding member has a bifurcated shape extending from the insertion portion so as to simultaneously shield the insertion portion that is attached and locked between the two openings of the housing having two openings, and the light emitted from the sleeve holder on the inner side of both openings. And a pair of light-shielding plates provided in a protruding manner.

遮光部材は、３つ以上の開口を有するハウジングの各開口における上端側もしくは下端側から装着して係止される差し込み部と、各開口内奥側のスリーブホルダーからの出射光を同時に遮蔽するよう差し込み部から各開口に対応して突設した複数の遮光板とから成る。   The light-shielding member shields the light emitted from the sleeve holder on the back side in each opening and the insertion portion that is mounted and locked from the upper end side or the lower end side in each opening of the housing having three or more openings. It consists of a plurality of light shielding plates protruding from the insertion portion corresponding to each opening.

差し込み部の内側には、両開口間に装着した遮光部材の離脱を阻止する係止片を備えている。   On the inner side of the insertion portion, there is provided a locking piece that prevents the light shielding member attached between both openings from being detached.

本発明によれば、双方向からの光コネクタプラグを受け入れ可能となる両端に複数の開口を有するハウジングの各開口内に割りスリーブを介して挿入されるスリーブホルダーを備えて成る光コネクタ相互接続用アダプタにおいて、１点部品による遮光部材で複数の開口内の遮光が同時に行えることで、製造上における作業性の向上と低コスト化を図ることができる。   According to the present invention, for optical connector interconnection comprising a sleeve holder inserted through each split sleeve into each opening of a housing having a plurality of openings at both ends capable of receiving an optical connector plug from both directions. In the adapter, light shielding in a plurality of openings can be performed simultaneously with a light shielding member made of one point component, so that workability in manufacturing and cost reduction can be achieved.

特に、一体構造のハウジング内に一対のスリーブホルダーが反対向きに配されて成る、例えば、２心用または４心等の光コネクタ相互接続用アダプタのいずれにおいても、１点部品の簡易構造による遮光部材でもって、複数の開口内の遮光が同時に行える。   In particular, in any one of two-fiber or four-fiber optical connector interconnection adapters in which a pair of sleeve holders are arranged in opposite directions in an integral housing, for example, light shielding by a simple structure of one-point components With a member, light shielding in a plurality of openings can be performed simultaneously.

さらに、差し込み部の内側には、両開口間に装着した遮光部材の離脱を阻止する係止片を備えたので、光コネクタプラグの挿脱によって遮光部材が離脱されるのを防止することができる。   Furthermore, since the locking piece for preventing the light shielding member attached between the openings from being detached is provided inside the insertion portion, it is possible to prevent the light shielding member from being detached due to the insertion / removal of the optical connector plug. .

以下、図面を参照して本発明を実施するための最良の一形態を説明する。
図において示される符号１は、例えばＬＣ型コネクタ等の一対の対向する光コネクタプラグを相互接続するための２心用の光コネクタ相互接続用アダプタを構成する外部ハウジングである。 The best mode for carrying out the present invention will be described below with reference to the drawings.
Reference numeral 1 shown in the drawing is an external housing constituting a two-fiber optical connector interconnection adapter for interconnecting a pair of opposing optical connector plugs such as LC type connectors.

この外部ハウジング１は、図１、図２および図５に示すように、一対の対向する光コネクタプラグＰを両端開口から相互に挿入可能とする矩形状の筒体によって形成され、外部ハウジング１内部の中央には、図２（ｂ）、図４に示すように、中央仕切部６が一体形成され、該中央仕切部６には、光コネクタプラグＰ先端部を装着保持するための、内側から一方の開口側へ向けて突出した状態の円筒状を成す左右一対のスリーブホルダー５を備えている。   As shown in FIGS. 1, 2, and 5, the outer housing 1 is formed by a rectangular cylindrical body that allows a pair of opposed optical connector plugs P to be inserted into each other from both end openings. 2 (b) and FIG. 4, a central partition 6 is integrally formed at the center of the optical connector plug P from the inner side for mounting and holding the optical connector plug P tip. A pair of left and right sleeve holders 5 having a cylindrical shape protruding toward one opening side are provided.

図３に示すように、外部ハウジング１内部には、この上側内壁面の中央長手方向に沿って、内部ハウジング２上側を挿入するための下面中央にガイド溝条７ａを備えた突部７が形成され、さらに、下側内壁面の中央長手方向に沿って、内部ハウジング２下側を挿入するための長手方向に沿って凹条のガイド溝条７ｂが形成されている。   As shown in FIG. 3, a protrusion 7 having a guide groove 7a at the center of the lower surface for inserting the upper side of the inner housing 2 is formed in the outer housing 1 along the central longitudinal direction of the upper inner wall surface. Furthermore, a concave guide groove 7b is formed along the longitudinal direction for inserting the lower side of the inner housing 2 along the central longitudinal direction of the lower inner wall surface.

そして、中央仕切部６側からスリーブホルダー５の内方に割りスリーブ３が嵌挿され、前記中央仕切部６に対向すべく、矩形板体の長手方向一端側に直角に配された左右一対の直角板それぞれに円筒状のスリーブホルダー４を突設して成る内部ハウジング２が、外部ハウジング１の他方の開口側から上下両ガイド溝条７ａ、７ｂに沿って挿入されることで、中央仕切部６を介して両スリーブホルダー４、５がそれぞれ反対向きに突出配置される。これにより、図２（ｂ）に示すように、両スリーブホルダー４、５内に、割りスリーブ３が内挿された状態となる。   Then, the split sleeve 3 is inserted into the sleeve holder 5 from the central partition 6 side, and a pair of left and right disposed at right angles to one end in the longitudinal direction of the rectangular plate body so as to face the central partition 6. The inner housing 2 formed by projecting a cylindrical sleeve holder 4 on each of the right-angle plates is inserted along the upper and lower guide grooves 7a and 7b from the other opening side of the outer housing 1, so that the central partition portion 6, both sleeve holders 4 and 5 are arranged to project in opposite directions. As a result, as shown in FIG. 2B, the split sleeve 3 is inserted into the sleeve holders 4 and 5.

また、図１または図３に示すように、外部ハウジング１の一端側は、両側板１ａ、１ｂおよび中央のガイド溝条７ａの上端面に、弧状の切欠部９を形成し、これに対応して内部ハウジング２の前部上端面にも弧状の切欠部１０を形成してある。したがって、外部ハウジング１内に内部ハウジング２を上下両ガイド溝条７ａ、７ｂに沿って中央仕切部６に当接するまで挿入すると、図１に示すように、外部ハウジング１の切欠部９と内部ハウジング２の切欠部１０とは合致する。
尚、この切欠部９、１０は、外部ハウジング１の両端開口側に形成されていても良い。 Further, as shown in FIG. 1 or FIG. 3, one end side of the outer housing 1 is formed with arc-shaped notches 9 on the upper end surfaces of the side plates 1a and 1b and the central guide groove 7a. An arcuate notch 10 is also formed on the front upper end surface of the inner housing 2. Therefore, when the inner housing 2 is inserted into the outer housing 1 along both the upper and lower guide grooves 7a and 7b until it comes into contact with the central partition 6, as shown in FIG. 2 notches 10 coincide with each other.
Note that the notches 9 and 10 may be formed on both ends of the outer housing 1.

また、外部ハウジング１の一端側には、図３乃至図５に示すように、両開口内奥側のスリーブホルダー４（またはスリーブホルダー５）からの出射光を同時に遮蔽するための遮光部材１１が着脱可能となるように取り付けられる。   Further, as shown in FIGS. 3 to 5, a light shielding member 11 for simultaneously shielding light emitted from the sleeve holder 4 (or the sleeve holder 5) on the inner side of both openings is provided on one end side of the outer housing 1. It is attached so that it can be detached.

すなわち、遮光部材１１は、図３および図６に示すように、内部ハウジング２の前部中央から左右両側面にかけて凹設した溝部１４に装着して係止されるコ字形状の差し込み部１２と、該差し込み部１２の両端から二股状に延設されて末広がりとなり且つ両先端側が互いに外方へ向くように屈曲された一対の遮光板１３とから成る。   That is, as shown in FIGS. 3 and 6, the light shielding member 11 includes a U-shaped insertion portion 12 that is attached and locked to a groove portion 14 that is recessed from the front center of the inner housing 2 to the left and right side surfaces. And a pair of light-shielding plates 13 that are bifurcated from both ends of the insertion portion 12 and are bent so that both ends are directed outward.

尚、差し込み部１２の互いに対向する内壁面には、図６（ｄ）に示すように、溝部１４に装着された差し込み部１２の離脱を阻止するため係止片１５を互いに内方に向けて切り起すことで突設してある。一方、溝部１４側には、この係止片１５を係止させるための係止孔１６が形成されている。   As shown in FIG. 6 (d), locking pieces 15 are directed to the inner wall surfaces of the insertion portion 12 facing each other inward to prevent the insertion portion 12 mounted in the groove portion 14 from being detached. Projected by cutting up. On the other hand, a locking hole 16 for locking the locking piece 15 is formed on the groove 14 side.

前記遮光板１３は、図５に示すように、開口内に光コネクタプラグＰを差し込んだ際に、当該遮光板１３を開口内壁面に押し退け、開口内から光コネクタプラグＰを抜き出した際に、当該遮光板１３を光遮蔽位置に復帰させるよう差し込み部１２から外方に向けて任意のバネ圧を付与して成る。   As shown in FIG. 5, when the optical connector plug P is inserted into the opening, the light shielding plate 13 pushes the light shielding plate 13 against the inner wall surface of the opening, and when the optical connector plug P is extracted from the opening, Arbitrary spring pressure is applied outward from the insertion portion 12 so as to return the light shielding plate 13 to the light shielding position.

次に、以上のように構成された最良の形態についての使用、組立、動作の一例について説明する。
本アダプタの組立に際し、先ず、図３に示すように、外部ハウジング１の中央仕切部６側からスリーブホルダー５の内方に向けて割りスリーブ３の略半分が嵌挿される。 Next, an example of use, assembly, and operation of the best mode configured as described above will be described.
When assembling the adapter, first, as shown in FIG. 3, approximately half of the split sleeve 3 is inserted from the central partition 6 side of the outer housing 1 toward the inside of the sleeve holder 5.

そして、内部ハウジング２が外部ハウジング１内の中央仕切部６位置まで上下両ガイド溝条７ａ、７ｂに沿って挿入される。このとき、内部ハウジング２のスリーブホルダー４内に割りスリーブ３の他の略半分が嵌挿される。   Then, the inner housing 2 is inserted along the upper and lower guide grooves 7a and 7b up to the position of the central partition 6 in the outer housing 1. At this time, the other substantially half of the split sleeve 3 is inserted into the sleeve holder 4 of the inner housing 2.

こうして、図２（ａ）に示すように、中央仕切部６を介して両スリーブホルダー４、５がそれぞれ反対向きに突出配置され、且つ両スリーブホルダー４、５内に完全に割りスリーブ３が内挿された状態となる。   Thus, as shown in FIG. 2 (a), the sleeve holders 4 and 5 protrude in opposite directions through the central partition 6, and the sleeve 3 is completely inserted into the sleeve holders 4 and 5. It will be inserted.

また、内部ハウジング２の溝部１４には、遮光部材１１が装着される。
このとき、差し込み部１２の係止片１５が溝部１４の係止孔１６に嵌って係止される。そして、図４に示すように、差し込み部１２の両端から二股状に延設されて末広がりとなった一対の遮光板１３が、両開口内奥側のスリーブホルダー４（またはスリーブホルダー５）にそれぞれ対向配置されることで、スリーブホルダー４（またはスリーブホルダー５）からの出射光が同時遮蔽される。 Further, the light shielding member 11 is mounted in the groove portion 14 of the inner housing 2.
At this time, the locking piece 15 of the insertion portion 12 is fitted and locked in the locking hole 16 of the groove portion 14. Then, as shown in FIG. 4, a pair of light shielding plates 13 extending from the both ends of the insertion portion 12 to expand toward the end are respectively attached to the sleeve holder 4 (or the sleeve holder 5) on the inner side of both openings. By facing each other, the emitted light from the sleeve holder 4 (or the sleeve holder 5) is simultaneously shielded.

光コネクタプラグＰの相互接続に際し、図５に示すように、外部ハウジング１の両端開口側から当該光コネクタプラグＰの先端部分が挿入され、両スリーブホルダー４、５内の割りスリーブ３内にそれぞれのフェルールＰ１が導入される。これによって光コネクタプラグＰ同士が接続される。   When the optical connector plugs P are interconnected, as shown in FIG. 5, the tip portions of the optical connector plugs P are inserted from both ends of the outer housing 1 and are inserted into the split sleeves 3 in the sleeve holders 4 and 5, respectively. The ferrule P1 is introduced. As a result, the optical connector plugs P are connected to each other.

このとき、遮光部材１１が装着されている側の開口内に光コネクタプラグＰを差し込んだ際には、図５（ａ）に示すように、当該光コネクタプラグＰによって当該遮光板１３が開口内壁面に押し退けられた状態となり、光コネクタプラグＰ挿入完了後には、図５（ｂ）に示すように、遮光部材１１が有するバネ圧作用によって光コネクタプラグＰの側面を保持した状態となる。また、開口内から光コネクタプラグＰを抜き出した際には、遮光部材１１自体の弾性力によって当該遮光板１３は光遮蔽位置に復帰させられる。   At this time, when the optical connector plug P is inserted into the opening on the side where the light shielding member 11 is mounted, the light shielding plate 13 is inserted into the opening by the optical connector plug P as shown in FIG. After the insertion of the optical connector plug P is completed, the side surface of the optical connector plug P is held by the spring pressure action of the light shielding member 11 as shown in FIG. 5B. When the optical connector plug P is extracted from the opening, the light shielding plate 13 is returned to the light shielding position by the elastic force of the light shielding member 11 itself.

また、上記した２心の外部ハウジング１による光コネクタ相互接続用アダプタを構成する替わりに、図７に示すように、４心用の外部ハウジング１による光コネクタ相互接続用アダプタを構成しても良い。   Further, instead of configuring the adapter for interconnecting optical connectors by the above-described two-core external housing 1, as shown in FIG. 7, an adapter for interconnecting optical connectors by the four-core external housing 1 may be configured. .

すなわち、外部ハウジング１内の中央仕切部６には光コネクタプラグの先端凹部を装着保持するための、内側から一方の開口側へ向けて突出した状態の円筒状を成す合計４本のスリーブホルダー５を備えている。また、図７に示すように、外部ハウジング１内を長手方向に沿って左右に仕切るように、中央仕切部６の前後面中央から開口側に向けて縦仕切部８が一体成形により設けられている。   That is, a total of four sleeve holders 5 that form a cylindrical shape projecting from the inside toward the one opening side for mounting and holding the tip recess of the optical connector plug in the central partition 6 in the outer housing 1. It has. Moreover, as shown in FIG. 7, the vertical partition part 8 is provided by integral molding from the center of the front-and-rear surface of the center partition part 6 toward the opening side so that the inside of the outer housing 1 may be divided into right and left along the longitudinal direction. Yes.

そして、この縦仕切部８を介しての左右開口内部には、これら上側内壁面の中央長手方向に沿って、内部ハウジング２上側を挿入するための下面中央にガイド溝条７ａを備えた突部７がそれぞれ形成され、さらに、これら下側内壁面の中央長手方向に沿って、内部ハウジング２下側を挿入するための凹条のガイド溝条７ｂがそれぞれ形成されている。   And the protrusion provided with the guide groove 7a in the lower surface center for inserting the upper side of the inner housing 2 along the central longitudinal direction of these upper inner wall surfaces inside the left and right openings through the vertical partitioning portion 8. 7 are formed, and further, guide groove strips 7b are formed along the central longitudinal direction of these lower inner wall surfaces to insert the lower side of the inner housing 2.

そして、既述した２心用の光コネクタ相互接続用アダプタと同様、スリーブホルダー５内に、割りスリーブ３が内挿され、前記中央仕切部６に対向すべく、矩形板体の長手方向一端側に直角に配された左右一対の直角板それぞれに円筒状のスリーブホルダー４を突設して成る２個の内部ハウジング２が、外部ハウジング１の他方の開口側の左右それぞれから上下両ガイド溝条７ａ、７ｂに沿って挿入されることで、中央仕切部６を介して４個のスリーブホルダー４、５がそれぞれ反対向きに突出配置される。これにより各スリーブホルダー４、５内に割りスリーブ３が完全に内挿された状態となる。   Then, like the two-fiber optical connector interconnection adapter described above, the split sleeve 3 is inserted into the sleeve holder 5 so that one end in the longitudinal direction of the rectangular plate body faces the central partition 6. Two inner housings 2 each formed by projecting a cylindrical sleeve holder 4 on each of a pair of right and left right-angle plates arranged at right angles to the right and left guide grooves from the left and right of the other opening side of the outer housing 1. By inserting along 7a, 7b, the four sleeve holders 4 and 5 are arranged in a projecting manner in opposite directions via the central partition 6. As a result, the split sleeve 3 is completely inserted into the sleeve holders 4 and 5.

外部ハウジング１の一端側には、両開口内奥側のスリーブホルダーからの出射光を同時に遮蔽するための遮光部材１１が着脱可能となるように取り付けられる。
この遮光部材１１は、既述した２心用の光コネクタ相互接続用アダプタに使用されているものと同様の構成を有する。すなわち、図３および図６に示すように、内部ハウジング２の前部中央から左右両側面にかけて凹設した溝部１４に装着して係止されるコ字形状の差し込み部１２と、該差し込み部１２の両端に形成された一対の遮光板１３と、差し込み部１２に突設された溝部１４からの離脱を阻止する係止片１５とを有する。 A light shielding member 11 for simultaneously shielding light emitted from the sleeve holders at the inner side of both openings is detachably attached to one end side of the outer housing 1.
The light shielding member 11 has the same configuration as that used for the two-fiber optical connector interconnection adapter described above.
