Description

本発明は、光コネクタプラグの高密度実装における光コネクタ用アダプタのガタ止め機構に関する。   The present invention relates to a rattling mechanism for an optical connector adapter in high-density mounting of an optical connector plug.

従来、光コネクタプラグの高密度実装における光コネクタ用アダプタ１００をパネルＰに取り付ける場合、図５（ａ）に示すように、該光コネクタ用アダプタ１００の左右両サイドにバネ等の抜け止め部１０１を設けたスナップイン方式を採っている。   Conventionally, when the optical connector adapter 100 in high-density mounting of the optical connector plug is attached to the panel P, as shown in FIG. 5A, the left and right sides of the optical connector adapter 100 are provided with retaining portions 101 such as springs. The snap-in method is used.

しかし、このようなスナップイン方式によると、パネルＰの取付孔Ｑと光コネクタ用アダプタ１００との間に若干のクリアランスが生じるため、パネルＰを動かすと光コネクタ用アダプタ１００がガタ付いてガタガタと音を出してしまうことがある。   However, according to such a snap-in method, a slight clearance is generated between the mounting hole Q of the panel P and the optical connector adapter 100. Therefore, when the panel P is moved, the optical connector adapter 100 is rattled. It may make a noise.

このようなガタガタ音が出るのを未然に防止するため、従来では、図５（ｂ）に示すように、光コネクタ用アダプタ１００の両サイドのフランジ１０２を大きくして、そこに孔１０３を設け、この孔１０３に例えばタッピングネジ等の締結部材１０４をパネルＰを貫通するようにねじ込むことで光コネクタ用アダプタ１００のガタ付きを無くす方式が採られている。
特になし In order to prevent such rattling noises from occurring, conventionally, as shown in FIG. 5B, the flanges 102 on both sides of the optical connector adapter 100 are enlarged, and holes 103 are provided there. A method of eliminating the play of the optical connector adapter 100 by screwing a fastening member 104 such as a tapping screw into the hole 103 so as to pass through the panel P is adopted.
nothing special

しかしながら、従来においては、光コネクタ用アダプタの両サイドにおけるフランジにネジ止めのスペースを設けた分だけ当該光コネクタ用アダプタの外形が大きくなるため、高密度の実装には向かないという問題点を有している。   However, the conventional optical connector adapter has a problem that it is not suitable for high-density mounting because the outer shape of the optical connector adapter is increased by the amount of space for screwing the flanges on both sides of the optical connector adapter. is doing.

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、光コネクタ用アダプタをパネルに取り付けた際に、光コネクタ用アダプタのガタ付きを容易且つ確実に無くすことができ、パネルに震動を与えてもガタガタ音の発生を防ぐことができ、しかも光コネクタ用アダプタへの光コネクタプラグの挿入が支障なく行えるものとした光コネクタ用アダプタのガタ止め機構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 when the optical connector adapter is attached to the panel, the backlash of the optical connector adapter is easily and reliably eliminated. Provides a rattling stop mechanism for optical connector adapters that can prevent rattling noises even when the panel is vibrated, and that can be inserted into the optical connector adapter without problems. The purpose is to do.

上述した課題を解決するため、本発明にあっては、光コネクタ用アダプタに形成された取付孔に挿入され、該取付孔内側で固定可能となるよう形成された複数の爪脚部と、中央面が若干***してなる係止面とを有する係止バネ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 plurality of claw leg portions formed so as to be inserted into a mounting hole formed in the adapter for an optical connector and fixed inside the mounting hole, A locking spring having a locking surface with a slightly raised surface is provided.

光コネクタ用アダプタの取付孔に挿入される爪脚部は、取付孔内側で折り込まれ、あるいは取付孔内に圧入されることにより固定されるものとなっている。   The claw leg portion inserted into the mounting hole of the optical connector adapter is fixed by being folded inside the mounting hole or being press-fitted into the mounting hole.

また、取付孔内側には、装着した係止バネと光コネクタ用プラグとが互いに干渉しない空間部を設けて成る。   In addition, a space portion in which the mounted locking spring and the optical connector plug do not interfere with each other is provided inside the mounting hole.

係止バネは、その係止面が光コネクタ用アダプタの上側壁に向けて順次圧潰されながらパネルにおけるアダプタ取付部に嵌着保持されて成る。   The locking spring is fitted and held on the adapter mounting portion of the panel while its locking surface is sequentially crushed toward the upper wall of the optical connector adapter.

本発明によれば、光コネクタ用アダプタをパネルに取り付けた際に、光コネクタ用アダプタのガタ付きを容易且つ確実に無くすことができ、パネルに震動を与えてもガタガタ音の発生を防ぐことができ、しかも光コネクタ用アダプタへの光コネクタプラグの挿入が支障なく行える。   According to the present invention, when the adapter for an optical connector is attached to the panel, the rattling of the adapter for the optical connector can be easily and surely eliminated, and the generation of rattling noise can be prevented even if the panel is vibrated. Moreover, the optical connector plug can be inserted into the optical connector adapter without any trouble.

光コネクタ用アダプタの取付孔に挿入される爪脚部は、取付孔内側で折り込まれ、あるいは取付孔内に圧入されることにより固定されるものとなっているので、ガタ付くことなくしっかりと固定されるのは勿論、作業性も良い。   The claw leg inserted into the mounting hole of the optical connector adapter is fixed by being folded inside the mounting hole or by being press-fitted into the mounting hole. Of course, workability is also good.

また、取付孔内側には、装着した係止バネと光コネクタ用プラグとが互いに干渉しない空間部を設けて成るので、係止バネが取り付けられていても、光コネクタ用アダプタへの光コネクタプラグの挿入が支障なく行える。   In addition, since the mounting spring is provided with a space where the installed locking spring and the optical connector plug do not interfere with each other, even if the locking spring is mounted, the optical connector plug to the optical connector adapter Can be inserted without any problem.

さらに、係止バネは、その係止面が光コネクタ用アダプタの上側壁に向けて順次圧潰されながらパネルにおけるアダプタ取付部に嵌着保持されて成るので、パネルのアダプタ取付部に対し、光コネクタ用アダプタをクリアランスを生じさせない状態でスムーズに嵌着させることができる。   Furthermore, the locking spring is fitted and held in the adapter mounting portion of the panel while the locking surface is sequentially crushed toward the upper side wall of the optical connector adapter. The adapter can be smoothly fitted in a state where no clearance is generated.

以下、図面を参照して本発明に係る光コネクタ用アダプタのガタ止め機構を実施するための最良の一形態を詳細に説明する。   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The best mode for carrying out the optical connector adapter ratchet mechanism according to the present invention will be described below in detail with reference to the drawings.

In addition, one fitting portion A of the optical connector plug and the other fitting portion B of the optical connector plug and other optical components are provided so that the optical axes coincide with each other.

アダプタハウジング２は、図３（ａ）乃至図３（ｃ）に示すように、上側壁、左右の側壁、底壁、１つの仕切壁とが一体に形成されて２つの嵌合部Ａ、Ａ（Ｂ、Ｂ）が並置されて成り、アダプタハウジング２の中央には略コ字枠状となった左右一対の接合端壁３ａが配置され、一方の嵌合部Ａにおける嵌合端３ｂ、および他方の嵌合部Ｂにおける接続端３ｃがそれぞれ水平方向に開口している。   As shown in FIGS. 3A to 3C, the adapter housing 2 is formed by integrally forming an upper side wall, left and right side walls, a bottom wall, and one partition wall to form two fitting portions A and A. (B, B) are juxtaposed, and a pair of right and left joint end walls 3a having a substantially U-shaped frame shape is disposed in the center of the adapter housing 2, and a fitting end 3b in one fitting portion A, and The connection ends 3c in the other fitting portion B are open in the horizontal direction.

また、アダプタハウジング２の中央部に配される左右一対の接合端壁３ａの一方には、一方の円筒４ａが嵌合端３ｂに向かって突設してあると共に、他方の接合端壁３ａには、他方の円筒４ｂが接続端３ｃに向かって形成してあり、両円筒４ａ、４ｂが光学軸上で中心軸を一致させて接合端壁３ａ同士を不図示の嵌合爪を介して係合固定することによってスリーブホルダー４が形成される。このとき、スリーブホルダー４内側に円筒状の割りスリーブ５が装着され保持されている。   One of the pair of left and right joining end walls 3a arranged in the center of the adapter housing 2 has one cylinder 4a projecting toward the fitting end 3b and the other joining end wall 3a. The other cylinder 4b is formed toward the connection end 3c, and both the cylinders 4a and 4b are aligned with the center axis on the optical axis so that the joining end walls 3a are engaged with each other via a fitting claw not shown. The sleeve holder 4 is formed by fixing together. At this time, a cylindrical split sleeve 5 is mounted and held inside the sleeve holder 4.

光コネクタ用プラグは、例えばＬＣ型のプラグ本体１１によって構成されており、該プラグ本体１１は、図３（ｄ）に示すように、比較的高強度なプラスチックから成るカップリングスリーブ１２と、このカップリングスリーブ１２内にフェルール用チューブ１３およびフェルールフレーム１４に装着されたフェルール１５と、フェルールフレーム１４の後端部外周に装着されるスプリング１６と、このスプリング１６を介してフェルールフレーム１４の後端部に嵌合するプラスチック製の本体フレーム１７と、該本体フレーム１７後部に装着されたブーツ２０とを具備する。   The plug for an optical connector is composed of, for example, an LC type plug main body 11, which includes a coupling sleeve 12 made of a relatively high strength plastic, as shown in FIG. A ferrule 15 mounted on the ferrule tube 13 and the ferrule frame 14 in the coupling sleeve 12, a spring 16 mounted on the outer periphery of the rear end of the ferrule frame 14, and a rear end of the ferrule frame 14 via the spring 16 A plastic main body frame 17 fitted to the portion and a boot 20 attached to the rear portion of the main body frame 17 are provided.

また、図３（ｄ）に示すように、カップリングスリーブ１２の外周面には、アダプタ本体１との係合およびその解除を行うための解除レバー１８がカップリングスリーブ１２に一体的に設けられている。この解除レバー１８は、カップリングスリーブ１２の先端部から後端部に向かって徐々にカップリングスリーブ１２外表面から離れるように傾斜して延設されており、その後端部は、本体フレーム１７の外周面に形成されたラッチレバー１９に当接するようカップリングスリーブ１２とは反対側に傾斜状に突出している。   Further, as shown in FIG. 3 (d), a release lever 18 for engaging with and releasing from the adapter body 1 is integrally provided on the coupling sleeve 12 on the outer peripheral surface of the coupling sleeve 12. ing. The release lever 18 is inclined and extended so as to gradually move away from the outer surface of the coupling sleeve 12 from the front end to the rear end of the coupling sleeve 12, and the rear end of the release lever 18 extends from the main body frame 17. It protrudes in an inclined manner on the opposite side to the coupling sleeve 12 so as to abut on a latch lever 19 formed on the outer peripheral surface.

次に、本発明に係る光コネクタ用アダプタのガタ止め機構について詳細に説明する。   Next, the rattling stop mechanism of the optical connector adapter according to the present invention will be described in detail.

このガタ止め機構としては、図１（ａ）、図１（ｂ）、図２に示すように、略矩形板片状の金属部材によって形成され、前後両端部それぞれの左右に爪脚部２２が略直角に折り曲げられた状態で突設され、且つ中央面が爪脚部２２の折り曲げ方向とは反対方向に若干***してなる係止面２３となった係止バネ２１を使用している。   As shown in FIGS. 1 (a), 1 (b), and 2, the rattling mechanism is formed of a substantially rectangular plate-shaped metal member, and claw leg portions 22 are provided on the left and right of both front and rear ends. A locking spring 21 is used which protrudes in a state of being bent at a substantially right angle and has a locking surface 23 whose central surface is slightly raised in the direction opposite to the bending direction of the claw leg 22.

また、アダプタハウジング２の上面には、前記係止バネ２１の各爪脚部２２を挿入するための例えば矩形小孔状の取付孔２４を前後左右４箇所に設けている。尚、この取付孔２４は、アダプタハウジング２の下面に設けることで、係止バネ２１がアダプタハウジング２の下面に取り付けられるようにしても良い。   In addition, on the upper surface of the adapter housing 2, for example, rectangular small hole-like mounting holes 24 for inserting the claw leg portions 22 of the locking spring 21 are provided at four positions in the front and rear, right and left. The attachment hole 24 may be provided on the lower surface of the adapter housing 2 so that the locking spring 21 is attached to the lower surface of the adapter housing 2.

そして、図３（ａ）乃至図３（ｃ）に示すように、アダプタハウジング２内部には、これら取付孔２４に連通する偏平状の空間部２５を両嵌合部Ａ、Ｂに対応して設けてあり、係止バネ２１の各爪脚部２２を、これらの取付孔２４に各挿入してから、当該空間部２５内で各爪脚部２２を互いに内方に向けて折り曲げることで係止バネ２１自体がしっかりとアダプタハウジング２に固定されるようにしている。   As shown in FIGS. 3A to 3C, a flat space 25 communicating with the mounting holes 24 is provided in the adapter housing 2 in correspondence with the fitting portions A and B. The claw leg portions 22 of the locking spring 21 are inserted into the mounting holes 24 and then the claw leg portions 22 are bent inward in the space portion 25. The stop spring 21 itself is firmly fixed to the adapter housing 2.

しかも、この空間部２５の存在により、図３（ｄ）に示すように、プラグ本体１１をアダプタハウジング２の各嵌合端３ｂに接続した際には、係止バネ２１は、プラグ本体１１の先端接続部分と干渉しないようになっている。   Moreover, due to the presence of the space 25, when the plug body 11 is connected to each fitting end 3b of the adapter housing 2 as shown in FIG. It does not interfere with the tip connection part.

また、図４に示すように、光コネクタ用アダプタは、４心コネクタ用のアダプタ本体１によって構成されていても良い。この場合、上側壁、左右の側壁、底壁、３つの仕切壁とが一体に形成されて４つの嵌合部Ａ、Ａ、Ａ、Ａ（Ｂ、Ｂ、Ｂ、Ｂ）が並置されて成る。   Moreover, as shown in FIG. 4, the adapter for optical connectors may be comprised by the adapter main body 1 for 4 core connectors. In this case, the upper side wall, the left and right side walls, the bottom wall, and the three partition walls are integrally formed, and the four fitting portions A, A, A, A (B, B, B, B) are juxtaposed. .

ところで、以上説明した上記の実施形態では、図３に示すように、係止バネ２１の各爪脚部２２は、取付孔２４に挿入した後内方に向けて折り曲げて固定されるものとなっているが、これに限定されるものではなく、例えば取付孔２４に各爪脚部２２を圧入することによって固定できるようにしても良い。   By the way, in the above-described embodiment described above, as shown in FIG. 3, each claw leg portion 22 of the locking spring 21 is bent and fixed inward after being inserted into the mounting hole 24. However, the present invention is not limited to this. For example, each claw leg portion 22 may be fixed by being press-fitted into the mounting hole 24.

次に、以上のように構成された本発明・光コネクタ用アダプタのガタ止め機構の最良の形態における係止バネ２１の組立手順の一例について詳細に説明する。   Next, an example of an assembling procedure of the locking spring 21 in the best mode of the rattling stop mechanism of the present invention / optical connector adapter configured as described above will be described in detail.

先ず、図３（ａ）に示すように、係止バネ２１の各爪脚部２２を各取付孔２４に挿入して、係止面２３の***方向が上方に向くように配置する。   First, as shown in FIG. 3A, each claw leg portion 22 of the locking spring 21 is inserted into each mounting hole 24 and arranged so that the protruding direction of the locking surface 23 faces upward.

そして、図３（ｂ）に示すように、空間部２５内に突出された各爪脚部２２を、例えばドライバーの先端部等で押し込んで、互いに内方に向けて折り曲げる。既述した圧入タイプでは、取付孔２４に各爪脚部２２を圧入するだけで良い。而して、係止バネ２１がしっかりとアダプタハウジング２に固定される。   And as shown in FIG.3 (b), each nail | claw leg part 22 protruded in the space part 25 is pushed in with the front-end | tip part etc. of a driver, for example, and it bends toward each other. In the press-fit type already described, it is only necessary to press-fit each claw leg portion 22 into the mounting hole 24. Thus, the locking spring 21 is firmly fixed to the adapter housing 2.

図３（ｃ）に示すように、パネルＰにおけるアダプタ取付部Ｑにアダプタハウジング２を挿入する。このとき、アダプタハウジング２は、その係止バネ２１の係止面２３がアダプタハウジング２の上側壁に向けて順次圧潰されながらしっかりとアダプタ取付部Ｑに嵌着保持される。   As shown in FIG. 3C, the adapter housing 2 is inserted into the adapter mounting portion Q in the panel P. At this time, the adapter housing 2 is firmly fitted and held in the adapter mounting portion Q while the locking surface 23 of the locking spring 21 is sequentially crushed toward the upper side wall of the adapter housing 2.

図３（ｄ）に示すように、プラグ本体１１をアダプタハウジング２の各嵌合端３ｂに接続する。このとき、係止バネ２１は、空間部２５内で各爪脚部２２が折り込まれているため、プラグ本体１１の先端接続部分とは干渉しない。   As shown in FIG. 3D, the plug body 11 is connected to each fitting end 3 b of the adapter housing 2. At this time, the locking spring 21 does not interfere with the tip connection portion of the plug body 11 because each claw leg portion 22 is folded in the space portion 25.
