Description

本発明は、光ＬＡＮ（Local Area Network）等の高速光通信に送受信機として用いられる光トランシーバに関し、特に通信機器側のケージに対して脱着可能に取り付けられるＳＦＰタイプ（ Small Form-Factor Pluggable）の光トランシーバおよびそのラッチ機構に関するものである。   The present invention relates to an optical transceiver used as a transmitter / receiver for high-speed optical communication such as an optical LAN (Local Area Network), and more particularly to an SFP type (Small Form-Factor Pluggable) that is detachably attached to a cage on a communication device side. The present invention relates to an optical transceiver and its latch mechanism.

高速ＬＡＮにおいて、デジタル電気信号と光信号とを相互に変換する光モジュールとして、光通信機器社間で取り決められたＭＳＡ（Multi Source Agreement）により規格化されたＳＦＦ（Small Form Factor ）タイプの光トランシーバやＳＦＰタイプの光トランシーバが広く用いられている。このうち、ＳＦＰタイプの光トランシーバは、光電気変換素子や回路基板等を内蔵しており、通信機器側の基板（例えば、マザーボード）上に設置されたケージに脱着可能に差し込むると、ケージ内の電気インターフェースコネクタに対して電気的、機械的に接続され、これにより光ファイバとの間で送受する光信号と、通信機器側の基板との間で送受する電気信号を互いに変換することで光通信を可能にしている。   SFF (Small Form Factor) type optical transceiver standardized by MSA (Multi Source Agreement) agreed between optical communication equipment companies as an optical module for mutual conversion between digital electrical signals and optical signals in high-speed LAN And SFP type optical transceivers are widely used. Among these, the SFP type optical transceiver contains a photoelectric conversion element, a circuit board, and the like, and if it is detachably inserted into a cage installed on a board (for example, a motherboard) on the communication equipment side, Electrically and mechanically connected to the electrical interface connector of the optical device, thereby converting the optical signal transmitted / received to / from the optical fiber and the electrical signal transmitted / received to / from the substrate on the communication equipment side to each other to convert the light. Communication is enabled.

このようなＳＦＰタイプの光トランシーバは、動作中に通信機器側のケージから外れると通信が中断したり、通信機器やトランシーバ自体が故障するおそれがあるため、ＭＳＡ規格ではこのような事故を防止するために、ラッチ機構（またはロック機構ともいう）によって光トランシーバをケージに対してしっかりと係止することを規定している。ラッチ機構の具体的な構造としては、係止手段と、この係止手段の係合状態を解除するロック解除手段とを備えた構造であることを規定している。このため、構造が簡単で光トランシーバの脱着を容易に行うことができるラッチ機構が従来から種々提案されている（例えば、特許文献１〜４参照）。   Such an SFP-type optical transceiver may be interrupted if it is disconnected from the cage on the side of the communication device during operation or the communication device or the transceiver itself may break down. Therefore, the MSA standard prevents such an accident. For this reason, it is defined that the optical transceiver is securely locked to the cage by a latch mechanism (also referred to as a lock mechanism). As a specific structure of the latch mechanism, it is defined that the latch mechanism has a structure including a locking unit and a lock releasing unit that releases the engagement state of the locking unit. For this reason, various latch mechanisms having a simple structure and capable of easily attaching / detaching an optical transceiver have been proposed (see, for example, Patent Documents 1 to 4).

特許文献１に記載された光モジュールのロック機構は、ケージ側に係止穴を有するばね板部を設け、光モジュールの下面側に前記係止穴に係合する突起状のロック部と、前記係止穴とロック部との係合状態を解除するロック解除用のレバーを設けている。ロック解除用レバーは、上下方向に回動自在に枢支された支軸部と、光モジュールの前方に突出するつまみ部と、ロック部の近傍に位置する凸部とを有し、ロック解除時につまみ部が指によって押し上げられると回動し、凸部がケージのばね板部を上方から押圧して下方に弾性変形させることにより、ロック部と係止穴との係合状態を解除するように構成されている。このため、光モジュールの取り出しに際しては、ロック解除用レバーを上方に回動させて係止穴とロック部の係合状態を解除する動作と、光モジュールをケージから前方に取り出す動作の２動作を行う必要がある。   The optical module locking mechanism described in Patent Document 1 includes a spring plate portion having a locking hole on the cage side, and a protruding locking portion that engages with the locking hole on the lower surface side of the optical module; An unlocking lever for releasing the engagement state between the locking hole and the lock portion is provided. The unlocking lever has a support shaft that is pivotably supported in the vertical direction, a knob that projects forward of the optical module, and a convex that is located near the lock. When the knob part is pushed up by the finger, it rotates, and the convex part presses the spring plate part of the cage from above and elastically deforms downward so that the engagement state between the lock part and the locking hole is released. It is configured. For this reason, when removing the optical module, the unlocking lever is rotated upward to release the engagement state between the locking hole and the lock portion, and the optical module is removed from the cage forward. There is a need to do.

特許文献２に記載された光モジュールのロック機構は、ケージ側に係止穴を設け、光モジュールのケース下面側に前記係止穴に係合する突起状のロック部を有するロック部材を上下方向に回動自在に設け、前記ケースの接続口に光ファイバケーブルコネクタを差し込み接続することにより、このコネクタが前記ロック部材を動作させてロック部を係止穴に係合させ、光ファイバケーブルコネクタを接続口から抜き取ることにより、ロック部材が元の状態に復帰して係止穴とロック部の係合状態を解除するように構成したものである。このため、光モジュールの取り出し時には、先ず光ファイバケーブルコネクタを光モジュールの接続口から抜き取り、しかる後光モジュールをケージから取り出し、取り出した後は再びコネクタを元の接続口に差し込む必要がある。   The locking mechanism of the optical module described in Patent Document 2 is provided with a locking hole on the cage side, and a lock member having a protruding lock portion that engages with the locking hole on the case lower surface side of the optical module. The optical fiber cable connector is inserted into and connected to the connection port of the case so that the connector operates the lock member to engage the lock portion with the locking hole. By pulling out from the connection port, the lock member returns to the original state and the engagement state between the locking hole and the lock portion is released. For this reason, when the optical module is taken out, it is necessary to first remove the optical fiber cable connector from the connection port of the optical module, then take out the optical module from the cage, and after removing the optical module, insert the connector into the original connection port again.

特許文献３に記載された光ファイバ・モジュールのラッチ外し機構は、光ファイバ・モジュールの下面側に第１、第２のアクチュエータを設け、第１のアクチュエータを操作するとこれに連動して第２のアクチュエータが光ファイバ・モジュールとケージとの係合状態を解除し、引き出しタブを引っ張ることにより光ファイバ・モジュールをケージから引き出すように構成したものである。このため、光ファイバ・モジュールの取り出しには、上記した特許文献１に記載されている従来装置と同様に第１のアクチュエータを回動させる動作と、光ファイバ・モジュールをケージから取り出す動作の２動作を必要とする。   The latch release mechanism of the optical fiber module described in Patent Document 3 is provided with first and second actuators on the lower surface side of the optical fiber module, and when the first actuator is operated, The actuator is configured to release the engaged state between the optical fiber module and the cage and pull the optical fiber module out of the cage by pulling the pull-out tab. For this reason, in order to take out the optical fiber module, two operations, that is, the operation of rotating the first actuator and the operation of taking out the optical fiber module from the cage as in the conventional apparatus described in Patent Document 1 described above. Need.

特許文献４に記載されたＳＦＰ光ファイバ・モジュールのレリーズ機構は、ＳＦＰケージ側に係止穴を有するばね板部を設け、ＳＦＰ光ファイバ・モジュールのケース下面側に前記ばね板部の係止穴に係合するラッチ（ロック部）と進退自在なエジェクターとを設けている。エジェクターは、光ファイバ・モジュールの取り出し時に押し込むことにより、前記ばね板部を下方に弾性変形させて係止穴とラッチの係合状態を解除するように構成されている。そして、ＳＦＰ光ファイバ・モジュールはレリーズ機構による係止状態が解除されると、ＳＦＰケージから引き出される。この場合、エジェクターの押込み方向と光ファイバ・モジュールの取り出し方向は互いに反対方向であるため、光ファイバ・モジュールの取り出し時には、エジェクターを押し込む動作と、光ファイバ・モジュールをケージから取り出す動作の２動作を必要とする。   The release mechanism of the SFP optical fiber module described in Patent Document 4 includes a spring plate portion having a locking hole on the SFP cage side, and the locking hole of the spring plate portion on the case lower surface side of the SFP optical fiber module. A latch (lock portion) that engages with the ejector and an ejector that can freely advance and retract are provided. The ejector is configured to release the engagement state between the latch hole and the latch by being elastically deformed downward by pushing the ejector when the optical fiber module is taken out. Then, when the SFP optical fiber module is released from the locking state by the release mechanism, it is pulled out from the SFP cage. In this case, the ejecting direction of the ejector and the removing direction of the optical fiber module are opposite to each other. Therefore, when removing the optical fiber module, two operations are performed: pushing the ejector and removing the optical fiber module from the cage. I need.

しかしながら、上記した従来の光トランシーバは、いずれもラッチ機構による光トランシーバの係止状態を解除する際にロック解除用部品を動作させるために加えられる操作力の方向と、解除後に光トランシーバをケージから取り出す際に加えられる操作力の方向とが異なるために、取り出す際の動作が２動作となり、取り出し作業が煩わしく時間がかかるという問題があった。   However, in each of the above conventional optical transceivers, the direction of the operating force applied to operate the unlocking component when releasing the locking state of the optical transceiver by the latch mechanism, and the optical transceiver after the release from the cage. Since the direction of the operating force applied at the time of taking out is different, there are two operations at the time of taking out, and there is a problem that the taking out operation is troublesome and takes time.

特に、特許文献１に記載された光モジュールは、ロック解除用レバーをケースの下面側に回動自在に設けているので、ケージへの差し込み時に光モジュールを上下方向から把持すると、指がロック解除用レバーを押さえ込んでロック方向に回動させてしまうために、ロック部がケージの開口端面に当たり光モジュールをケージに差し込めないという問題があった。また、ロック解除用レバーを復帰方向に付勢するためのばねを必要とし、部品点数が増加するという問題もあった。   In particular, the optical module described in Patent Document 1 is provided with an unlock lever on the lower surface side of the case so that the finger is unlocked when the optical module is grasped from above and below when inserted into the cage. Since the lever is pushed down and rotated in the locking direction, there is a problem that the optical module cannot be inserted into the cage because the locking portion hits the opening end surface of the cage. In addition, there is a problem that a spring for urging the unlocking lever in the return direction is required, and the number of parts increases.

特許文献２に記載された光モジュールは、特許文献１の光モジュールと同様な問題に加えて、着脱時の動作が１動作増えるという問題があった。すなわち、光ファイバケーブルコネクタにロック解除用レバーを兼用させると、光モジュールの着脱時に同コネクタを光モジュールから取り外す動作と、元に戻す動作の２動作を必要とするからである。   The optical module described in Patent Document 2 has a problem that the number of operations at the time of attachment / detachment increases by one in addition to the same problem as the optical module of Patent Document 1. That is, if the optical fiber cable connector is also used as the unlocking lever, two operations are required: an operation for removing the connector from the optical module and an operation for returning the optical module when the optical module is attached / detached.

特許文献４に記載されたＳＦＰ光ファイバ・モジュールは、エジェクターの押込み方向とＳＦＰ光ファイバ・モジュールの取り出し方向とが正反対な方向であるため、取り出し時に１本の指でエジェクタを押し込んで係止穴とロック部の係合状態を解除した状態を保持しつつ、他の２本の指でＳＦＰ光ファイバ・モジュールを把持してケージから引き出さなければならなず、指の使い方が難しく取り出し操作に熟練を要するという問題があった。   In the SFP optical fiber module described in Patent Document 4, since the push-in direction of the ejector and the take-out direction of the SFP optical fiber module are opposite to each other, the ejector is pushed with one finger at the time of take-out. While holding the engagement state of the lock part and the other two fingers, the SFP optical fiber module must be grasped and pulled out of the cage, making it difficult to use the fingers and skilled in taking out There was a problem of requiring.

本発明は上記した従来の問題を解決するためになされたものであり、その目的とするところは、構造簡易にして指の使い方が自然で、係止手段の係合状態を解除する動作と光トランシーバをケージから取り出す動作を実質的に連続した１動作とすることにより、取り出し作業を容易かつ迅速に行うことが可能な光トランシーバおよびそのラッチ機構を提供することにある。   The present invention has been made to solve the above-described conventional problems. The object of the present invention is to simplify the structure and use the finger naturally, and to release the engagement state of the locking means and the light. It is an object of the present invention to provide an optical transceiver and a latch mechanism thereof that can easily and quickly perform the operation of taking out the transceiver from the cage as one substantially continuous operation.

An engaging portion that engages with the hole and an insertion portion that is inserted into the cage; and the elastically deforming portion of the cage is elastically deformed in a direction away from the engaging portion, whereby the locking hole and the engaging portion And a lever for operating the latch release lever. The latch release lever is provided on the lower side of the receptacle part so as to be movable back and forth, and the operation lever is operated. The lever operates the latch release lever by being rotated by an operating force in the same direction as the direction in which the insertion portion is removed from the cage.

第２の発明に係る光トランシーバは、前記操作レバーが、前記レセプタクル部の両側面に軸によって回動自在に枢支された左右一対の支軸部と、前記一対の支軸部を連結する連結部と、前記連結部にそれぞれ延設されることにより前記レセプタクル部の上方および前方に延在する操作部および押圧部と、前記連結部に形成されたプラグ用凹部とを有し、前記光コネクタプラグが前記プラグ用凹部を通って前記レセプタクル部の接続口に差し込まれるものである。   An optical transceiver according to a second aspect of the present invention is a connection for connecting the pair of support shafts to a pair of left and right support shafts pivotally supported by shafts on both side surfaces of the receptacle portion. The optical connector, and an operating portion and a pressing portion that extend upward and forward of the receptacle portion by being respectively extended to the connecting portion, and a plug recess formed in the connecting portion. The plug is inserted into the connection port of the receptacle through the plug recess.

第３の発明に係る光トランシーバは、前記ラッチ解除用レバーが、前記レセプタクル部の前方に位置し前記操作レバーの押圧部によって押圧される被押圧部と、前記差し込み部の下面側に位置し前記ケージの弾性変形部を前記係合部から離間する方向に弾性変形させるラッチ解除部とを有するものである。   In the optical transceiver according to a third aspect of the invention, the latch release lever is located in front of the receptacle part and pressed by the pressing part of the operation lever, and is located on the lower surface side of the insertion part. And a latch releasing portion that elastically deforms the elastically deforming portion of the cage in a direction away from the engaging portion.

第４の発明に係る光トランシーバのラッチ機構は、通信機器側のケージに対して光トランシーバを着脱可能に係止する光トランシーバのラッチ機構において、前記ケージに設けられた係止穴を有する弾性変形部と、前記光トランシーバの前記ケージに差し込まれる差し込み部の下面側に突設され前記ケージの係止穴に係合する係合部と、前記光トランシーバの光コネクタプラグが接続されるレセプタクル部の下部側に前後移動自在に設けられ前記弾性変形部を前記係合部から離間する方向に弾性変形させることにより前記係止穴と前記係合部との係合状態を解除するラッチ解除用レバーと、前記レセプタクル部に回動自在に設けられた操作レバーとを備え、前記操作レバーは前記光トランシーバの差し込み部を前記ケージから取り出す方向と同方向の操作力によって回動されることにより、前記ラッチ解除用レバーを動作させるものである。   An optical transceiver latch mechanism according to a fourth aspect of the invention is an optical transceiver latch mechanism for detachably locking an optical transceiver with respect to a cage on the side of a communication device, and elastic deformation having a locking hole provided in the cage. A receptacle portion to which an optical connector plug of the optical transceiver is connected, an engaging portion that projects from a lower surface side of an insertion portion that is inserted into the cage of the optical transceiver, and engages with a locking hole of the cage A latch release lever that is provided on the lower side so as to be movable back and forth, and that elastically deforms the elastic deformation portion in a direction away from the engagement portion, thereby releasing the engagement state between the engagement hole and the engagement portion; An operation lever rotatably provided on the receptacle portion, and the operation lever has a direction to take out the insertion portion of the optical transceiver from the cage. By being rotated by the direction of the operation force, in which operating the latch release lever.

第１、第４の本発明においては、操作レバーに加えられる操作力の方向が光トランシーバをケージから取り出す方向と一致しているので、操作レバーを動作させて係合部と係止穴との係合状態を解除した後も引き続き操作レバーに同方向の操作力を加え続ければ、この操作力が光トランシーバをケージから取り出すための力として働き、ラッチ機構の係止解除動作と光トランシーバの取り出し動作を実質的に連続した１動作で行うことができる。したがって、光トランシーバを２本の指で把持しなくても操作レバーの操作部に引っ掛けている１本の指による取り出しが可能で、光トランシーバの取り出し作業を容易かつ迅速に行うことができる。

Projects forward. The pressed portion 37B is bent and formed substantially vertically upward at the front end of the main body 37A, and has a size that can enter the concave portion 34 of the front plate 25A. The recessed portion 34 restricts the rearward movement of the latch release lever 37 when the pressed portion 37 contacts the inner wall surface. The latch release portion 37C is formed to be bent obliquely upward at an angle of approximately 45 ° at the rear end of the main body 37A, and protrudes rearward of the holder 25 from the insertion hole 39 provided in the bent portion 29 of the lower plate 28. ing. The latch release portion 37 </ b> C is positioned in front of the engaging portion 17 of the case 13 and is in contact with the lower surface of the rear end portion 28 </ b> B of the lower plate 28.

前記操作レバー３８は、前記ラッチ解除用レバー３７と同様にステンレス薄板の折り曲げ加工によって形成されることにより、前記ホルダー２５の左右両側板２５Ｂ，２５Ｃに軸４４によって回動自在に枢支された左右一対の支軸部３８Ａ，３８Ａと、レセプタクル部１１の前方に位置し前記一対の支軸部３８Ａ，３８Ａの前端を連結する連結部３８Ｂと、この連結部３８Ｂの上下縁にそれぞれ一体に延設された操作部３８Ｃおよび押圧部３８Ｄとで構成されている。連結部３８Ｂの左端部側には、操作レバー３８の回動時における光コネクタプラグ２４と連結部３８Ｂとの干渉を防止するプラグ用凹部４５が形成されている。操作部３８Ｃはホルダー２５の上方に延在し、先端には指の掛かりを良くする掛かり部４６（図３、図５）が折り曲げ形成されている。押圧部３８Ｄは、レセプタクル部１１の前方でかつ前記ラッチ解除用レバー３７の被押圧部３７Ｂよりも前方に位置し、下端には係止手段３６の係止状態解除時に被押圧部３７Ｂを押圧する左右一対の押圧片４７が後方に向かって一体に突設されている。操作部３８Ｃと押圧部３８Ｄの交差角度は１２０°、操作レバー３８の最大回動角度α（図８）は２６°程度である。また、操作レバー３８は、操作部３８Ｃの回動範囲がレセプタクル部１１の上方領域内に制限されており、不使用時においては、操作部３８Ｃが図３に実線で示すようにレセプタクル部１１の上面に接触し、ラッチ解除用レバー３７をフリーな状態に保持しておくことが好ましい。   The operating lever 38 is formed by bending a stainless steel thin plate in the same manner as the latch releasing lever 37, so that the left and right plates 25B and 25C of the holder 25 are pivotally supported by the shaft 44 so as to be rotatable. A pair of support shaft portions 38A, 38A, a connection portion 38B that is positioned in front of the receptacle portion 11 and connects the front ends of the pair of support shaft portions 38A, 38A, and an upper and lower edge of the connection portion 38B are integrally extended. The operation unit 38C and the pressing unit 38D are configured. A plug recess 45 that prevents interference between the optical connector plug 24 and the connecting portion 38B when the operation lever 38 is rotated is formed on the left end side of the connecting portion 38B. The operation portion 38C extends above the holder 25, and a hook portion 46 (FIGS. 3 and 5) for improving the hooking of a finger is formed at the tip. The pressing portion 38D is positioned in front of the receptacle portion 11 and in front of the pressed portion 37B of the latch release lever 37, and presses the pressed portion 37B at the lower end when the locking means 36 is released. A pair of left and right pressing pieces 47 are integrally protruded rearward. The crossing angle between the operating portion 38C and the pressing portion 38D is 120 °, and the maximum turning angle α (FIG. 8) of the operating lever 38 is about 26 °. Further, the operating lever 38 has a rotation range of the operating portion 38C limited within the upper region of the receptacle portion 11. When the operating lever 38 is not used, the operating portion 38C has the receptacle portion 11 as shown by a solid line in FIG. It is preferable to keep the latch release lever 37 in a free state by contacting the upper surface.

次に、上記構造からなる光トランシーバ４のケージ２に対する着脱作業を図６〜図９に基づいて説明する。図６は光トランシーバ４の差し込み部１０をケージ２に途中まで差し込んだ状態を示す図である。光トランシーバ４の装着に際しては、レセプタクル部１１を２本の指、例えば親指１００と人差し指１０１とで上下方向から把持して差し込み部１０をケージ２に挿入する。親指１００と人差し指１０１でレセプタクル部１１を上下方向から把持すると、操作レバー３８の操作部３８Ｃは人差し指１０１によってレセプタクル部１１の上面に押し付けられる。   Next, an attaching / detaching operation of the optical transceiver 4 having the above structure with respect to the cage 2 will be described with reference to FIGS. FIG. 6 is a view showing a state where the insertion portion 10 of the optical transceiver 4 is inserted into the cage 2 halfway. When the optical transceiver 4 is mounted, the receptacle part 11 is grasped from the vertical direction by two fingers, for example, the thumb 100 and the index finger 101, and the insertion part 10 is inserted into the cage 2. When the receptacle part 11 is grasped from the vertical direction by the thumb 100 and the index finger 101, the operation part 38 </ b> C of the operation lever 38 is pressed against the upper surface of the receptacle part 11 by the index finger 101.

図７に示すように差し込み部１０の全長をケージ２に差し込むと、ホルダー２５の後端面がケージ２の前面側開口端面に当接してそれ以上の挿入が阻止される。差し込み部１０がケージ２に差し込まれると、係合部１７は弾性片７の前端部７ａ（図１）に乗り上げて頂部を通過すると係止穴６に係合して光トランシーバ４をケージ２に係止する。また、差し込み部１０をケージ２に差し込み、係合部１７が係止穴６に係合すると、回路基板１４のカードエッジコネクタ２２（図１）はケージ２内の電気インターフェースコネクタに電気的、機械的に接続され、これにより光コネクタ４がケージ２に対して着脱可能に装着される。この装着状態において、ケース１３の上面側に設けられている一対の弾性片１５はケージ２の上板２７の下面に圧接し、その弾発力で差し込み部１０を底板２８に押し付けることにより、光トランシーバ４をしっかりと固定し上下左右方向の遊動を防止する。   As shown in FIG. 7, when the entire length of the insertion portion 10 is inserted into the cage 2, the rear end surface of the holder 25 comes into contact with the front-side opening end surface of the cage 2 and further insertion is prevented. When the insertion portion 10 is inserted into the cage 2, the engaging portion 17 rides on the front end portion 7 a (FIG. 1) of the elastic piece 7 and passes through the top portion, and engages with the locking hole 6, thereby bringing the optical transceiver 4 into the cage 2. Lock. When the insertion portion 10 is inserted into the cage 2 and the engagement portion 17 is engaged with the locking hole 6, the card edge connector 22 (FIG. 1) of the circuit board 14 is electrically and mechanically connected to the electrical interface connector in the cage 2. Thus, the optical connector 4 is detachably attached to the cage 2. In this mounted state, the pair of elastic pieces 15 provided on the upper surface side of the case 13 are in pressure contact with the lower surface of the upper plate 27 of the cage 2, and the insertion portion 10 is pressed against the bottom plate 28 by its elastic force. The transceiver 4 is firmly fixed to prevent the vertical and horizontal movement.

ケージ２に装着されている光トランシーバ４を取り出すときは、図８に示すように人差し指１０１を操作レバー３８の操作部３８Ｃの掛かり部４６に引っ掛けてケージ２の前方に引く。   When the optical transceiver 4 attached to the cage 2 is taken out, the index finger 101 is hooked on the hanging portion 46 of the operating portion 38C of the operating lever 38 as shown in FIG.

人差し指１０１によって操作レバー３８の操作部３８Ｃを前方に引くと、操作レバー３８は軸４４を中心として図８において反時計方向に回動し、押圧部３８Ｄの押圧子４７がラッチ解除用レバー３７の被押圧部３７Ｂを押圧する。このため、ラッチ解除用レバー３７は、下板２８の前端部２８Ａの上面に沿って後方に移動してラッチ解除部３７Ｃをケージ２内に挿入させる。そして、ラッチ解除用レバー３７は、操作レバー３８が最大角度（α）回動すると、後方に最大ストローク移動して被押圧部３７Ｂが前面板２５Ａの凹部３４（図１）の内壁面に押し付けられることにより停止し、それ以上の移動を制限される。ラッチ解除用レバー３７のラッチ解除部３７Ｃは、ケージ２内に所定量挿入されると、弾性片７に当たってこれを下方に弾性変形させることにより係止穴６と係合部１７との係合状態を解除する。図８はこの状態を示す。   When the operating portion 38C of the operating lever 38 is pulled forward by the index finger 101, the operating lever 38 rotates counterclockwise in FIG. 8 about the shaft 44, and the pressing element 47 of the pressing portion 38D moves the latch releasing lever 37. The pressed part 37B is pressed. For this reason, the latch release lever 37 moves rearward along the upper surface of the front end portion 28 </ b> A of the lower plate 28 to insert the latch release portion 37 </ b> C into the cage 2. Then, when the operation lever 38 rotates by the maximum angle (α), the latch release lever 37 moves backward by the maximum stroke, and the pressed portion 37B is pressed against the inner wall surface of the recess 34 (FIG. 1) of the front plate 25A. Is stopped, and further movement is restricted. When the latch release portion 37C of the latch release lever 37 is inserted into the cage 2 by a predetermined amount, the latch release portion 37C hits the elastic piece 7 and elastically deforms it downward to engage the locking hole 6 with the engagement portion 17. Is released. FIG. 8 shows this state.

操作レバー３８の回動によりラッチ解除用レバー３７を動作させて弾性片７を下方に撓ませ、係止穴６と係合部１７との係合状態を解除した後も、操作レバー３８の掛かり部４６に引っ掛けている人差し指１０をさらに前方に引き続けると、光トランシーバ４は図９に示すようにケージ２から徐々に引き出され、回路基板１４のカードエッジコネクタ２２がケージ２内の電気インターフェースコネクタから外れる。したがって、光トランシーバ４をケージ２から取り出すことができる。この取り出し時においては必ずしも２本の指で把持する必要はないが、光トランシーバ４が傾いたりしないようにするために親指１００でレセプタクル部１１の下面を支えておくことが好ましい。光トランシーバ４をケージ２から取り出すと弾性片７，１５はそれぞれ元の状態に弾性復帰する。   Even after the latch release lever 37 is operated by the rotation of the operation lever 38 to bend the elastic piece 7 downward and the engagement state between the engagement hole 6 and the engagement portion 17 is released, the engagement of the operation lever 38 is maintained. When the index finger 10 hooked on the portion 46 is further pulled forward, the optical transceiver 4 is gradually pulled out from the cage 2 as shown in FIG. 9, and the card edge connector 22 of the circuit board 14 is connected to the electrical interface connector in the cage 2. Deviate from. Therefore, the optical transceiver 4 can be taken out from the cage 2. At the time of taking out, it is not always necessary to hold with two fingers, but it is preferable to support the lower surface of the receptacle portion 11 with the thumb 100 in order to prevent the optical transceiver 4 from tilting. When the optical transceiver 4 is removed from the cage 2, the elastic pieces 7 and 15 are restored to their original states.

このように本発明においては、係止穴６と係合部１７との係合状態を解除するとき、操作レバー３８を回動させる力の方向を前方とし、光トランシーバ４をケージ２から取り出す方向と一致させているので、光トランシーバ４の取り出し時に操作レバー３８の操作部３８Ｃに対して光トランシーバ４を取り出す方向の力を加え続けることにより、ラッチ機構４０の係止解除動作と光トランシーバ４の取り出し動作を実質的に連続した１動作で行うことができる。したがって、光トランシーバ４を２本の指で必ずしも把持する必要がなく操作レバー３８の操作部３８Ｃに１本の指を引っ掛けるだけでも取り出すことができ、光トランシーバ４の取り出し作業を容易かつ迅速に行うことができる。   As described above, in the present invention, when the engagement state between the locking hole 6 and the engaging portion 17 is released, the direction of the force for rotating the operation lever 38 is set to the front, and the optical transceiver 4 is taken out from the cage 2. Therefore, when the optical transceiver 4 is taken out, by continuing to apply a force in the direction of taking out the optical transceiver 4 to the operation portion 38C of the operation lever 38, the latch release operation of the latch mechanism 40 and the optical transceiver 4 The take-out operation can be performed in one substantially continuous operation. Therefore, it is not always necessary to hold the optical transceiver 4 with two fingers, and the optical transceiver 4 can be taken out by simply hooking the finger on the operation portion 38C of the operation lever 38, and the optical transceiver 4 can be taken out easily and quickly. be able to.

また、本発明においては、操作レバー３８によって動作されるラッチ解除用レバー３７の本体３７Ａをレセプタクル部１１内に前後移動自在に組み込むだけでよいので、ラッチ解除用レバー３７の取付けが簡単で、復帰用ばねを設ける必要がなく部品点数を削減できる。さらに、レセプタクル部１１の上下面を指で把持してもラッチ解除用レバー３７を指で押さえつけたり、操作レバー３８がラッチ解除用レバー３７を動作させたりすることがなく、光トランシーバ４をケージ２に確実に装着することができる。   Further, in the present invention, since the main body 37A of the latch release lever 37 operated by the operation lever 38 has only to be incorporated in the receptacle part 11 so as to be movable back and forth, the latch release lever 37 can be easily mounted and returned. There is no need to provide a spring for use, and the number of parts can be reduced. Further, even if the upper and lower surfaces of the receptacle part 11 are grasped with a finger, the latch release lever 37 is not pressed with the finger, and the operation lever 38 does not operate the latch release lever 37, so that the optical transceiver 4 can be connected to the cage 2. Can be securely attached.

また、操作レバー３８の連結部３８Ｂにプラグ用凹部４５を設けているので、操作レバー３８を回動させても、光コネクタプラグ２４が連結部３８Ｂに当たって操作レバー３８の回動を阻害するようなことはない。   Further, since the plug recess 45 is provided in the connecting portion 38B of the operating lever 38, even if the operating lever 38 is rotated, the optical connector plug 24 hits the connecting portion 38B and obstructs the rotation of the operating lever 38. There is nothing.

さらに、本発明においては、操作レバー３８の操作部３８Ｃの回動範囲をレセプタクル部１１の上方のみとし、その回動範囲を水平面から２６°程度の比較的狭い範囲としているので、光トランシーバ４をケージから取り出すときの力の損失を少なくことができる。すなわち、操作部３８Ｃの回動範囲を広くすると、操作部３８Ｃに加える操作力の方向が回動角度によって変化するため、力の損失が大きくなる。また、力の方向が変化すると、光トランシーバ４が傾き、取り出しにくくなる。これに対して、操作部３８Ｃの回動範囲が小さければ、力の方向の変化が少なく安定した状態で光トランシーバ４をケージ２から引き出すことができる。   Furthermore, in the present invention, the rotation range of the operation portion 38C of the operation lever 38 is set only above the receptacle 11, and the rotation range is a relatively narrow range of about 26 ° from the horizontal plane. Loss of force when removing from the cage can be reduced. That is, when the rotation range of the operation unit 38C is widened, the direction of the operation force applied to the operation unit 38C changes depending on the rotation angle, so that the loss of force increases. Further, when the direction of the force changes, the optical transceiver 4 is tilted and becomes difficult to take out. On the other hand, if the rotation range of the operation unit 38C is small, the optical transceiver 4 can be pulled out from the cage 2 in a stable state with little change in the direction of force.

本発明は光トランシーバ４をＯＬＴとＯＮＵ間の光通信に用いた例を示したが、これに限らず、他の光通信、例えばＳＯＮＥＴ（Synchronous Optical Network）、ＳＤＨ（
Synchronous Digital Hierarchy）等に用いることが可能である。 The present invention has shown an example in which the optical transceiver 4 is used for optical communication between the OLT and the ONU.
