しかしながら、従来技術では、ロックレバーの被操作部の弾性変形を利用しているため、コネクタのロック及びロック解除を繰り返した時等において徐々に塑性変形が生じてロック又はロック解除が確実にできなくなる等のおそれがあった。 However, in the prior art, since the elastic deformation of the operated portion of the lock lever is used, plastic deformation gradually occurs when the connector is repeatedly locked and unlocked, and the locking or unlocking cannot be reliably performed. There was a risk of such things.

本発明の１つの態様は、コネクタであって、ハウジングと、ロック部材と、リリース部材とを備え、前記ロック部材は、第１延伸部、第２延伸部及び回転軸を有し、前記第２延伸部には他部材と係合させるためのラッチが設けられており、前記第１延伸部と前記第２延伸部とが前記回転軸によって連接され、前記回転軸を回転中心として前記ハウジングに装着されており、前記リリース部材は、前記ハウジングに対して相対的に移動可能に配置され、前記ハウジングに対して前記リリース部材を相対的に移動させることで、前記回転軸を回転中心として前記第１延伸部及び前記第２延伸部を回動させることで前記ラッチを移動させてロック状態とリリース状態とを選択的に切り換えることを特徴とするコネクタである。 One aspect of the present invention is a connector comprising a housing, a locking member, and a release member, wherein the locking member has a first stretched portion, a second stretched portion, and a rotating shaft, said second. The stretched portion is provided with a latch for engaging with another member, and the first stretched portion and the second stretched portion are connected by the rotation shaft and mounted on the housing with the rotation shaft as the rotation center. The release member is arranged so as to be relatively movable with respect to the housing, and by moving the release member relative to the housing, the first release member is centered on the rotation axis. The connector is characterized in that the latch is moved by rotating the stretched portion and the second stretched portion to selectively switch between a locked state and a released state.

ここで、前記リリース部材は、ハンドル部、格納溝、位置規制部及び操作突起部を有し、前記位置規制部は、前記ハウジングを装着できるような形状とされ、前記ハンドル部は、前記位置規制部の前記ハウジングを挿入する側の反対側に延伸して凸設され、前記格納溝は、前記ハンドル部内に設置され、前記ハウジングに対して前記リリース部材を前記ハウジングを挿入する側の反対側に向けて相対的に移動させることで、前記操作突起部が前記ロック部材の当接部に当接されて前記回転軸を回転中心として前記ロック部材が回動させられて前記ラッチがロック状態からリリース状態に遷移することが好適である。 Here, the release member has a handle portion, a storage groove, a position restricting portion, and an operation protrusion portion, the position restricting portion is shaped so that the housing can be mounted, and the handle portion is the position restricting portion. The housing is extended and projected to the opposite side of the portion to the side where the housing is inserted, and the storage groove is installed in the handle portion, and the release member is placed on the opposite side of the housing to the side where the housing is inserted. By relatively moving toward the lock member, the operation protrusion is brought into contact with the contact portion of the lock member, the lock member is rotated around the rotation axis, and the latch is released from the locked state. It is preferable to transition to the state.

本発明の実施の形態における光コネクタ１００は、図１の斜視図及び図２の分解斜視図に示すように、ハウジング１０、フェルール２０、ロック部材３０及びリリース部材４０を含んで構成される。 As shown in the perspective view of FIG. 1 and the exploded perspective view of FIG. 2, the optical connector 100 according to the embodiment of the present invention includes a housing 10, a ferrule 20, a lock member 30, and a release member 40.

光コネクタ１００は、例えば、フェルール２０に光ファイバを装着し、相手側となるアダプタやモジュール等に設けられた装着穴に挿入及び嵌合させて相手側の光ファイバと光学的に結合させるために用いられる。ただし、光コネクタ１００の適用分野は、光ファイバの結合に限定されるものではない。 The optical connector 100 is, for example, for mounting an optical fiber on a ferrule 20 and inserting and fitting it into a mounting hole provided in an adapter or module on the other side to optically connect the optical fiber to the optical fiber on the other side. Used. However, the field of application of the optical connector 100 is not limited to the coupling of optical fibers.

また、図３及び図４は、光コネクタ１００におけるハウジング１０、フェルール２０、ロック部材３０及びリリース部材４０を組み合わせたときの構成を示す断面図である。図３は、光コネクタ１００を相手側となるアダプタやモジュール等に装着してロックしたときの状態（ロック状態）を示す。図４は、光コネクタ１００を相手側となるアダプタやモジュール等から取り外すときにロックを解除した状態（リリース状態）を示す。 3 and 4 are cross-sectional views showing the configuration of the optical connector 100 when the housing 10, the ferrule 20, the lock member 30, and the release member 40 are combined. FIG. 3 shows a state (locked state) when the optical connector 100 is attached to an adapter, module, or the like on the other side and locked. FIG. 4 shows a state in which the lock is released (release state) when the optical connector 100 is removed from the adapter, module, or the like on the other side.

ハウジング１０は、内部に軸心に沿って穿設された収容溝１１を備える。本実施の形態では、２つのフェルール２０が設けられている。フェルール２０は、ハウジング１０の前端部から突出するように軸心に平行に収容溝１１の左右両側のそれぞれに設置される。 The housing 10 includes a housing groove 11 bored therein along the axis. In this embodiment, two ferrules 20 are provided. The ferrule 20 is installed on each of the left and right sides of the accommodating groove 11 in parallel with the axis so as to project from the front end portion of the housing 10.

ロック部材３０は、第１延伸部３１、第２延伸部３２、回転軸３３、当接部３４及びラッチ３５を含む。第１延伸部３１と該第２延伸部３２とが回転軸３３の両側に連接される。すなわち、第１延伸部３１と第２延伸部３２とが連続するように接続され、その中間部から両側に突出するように回転軸３３が設けられる。また、第２延伸部３２の中間部には回転軸３３からラッチ３５に向けて傾斜した当接部３４を有する溝が設けられる。 The lock member 30 includes a first stretching portion 31, a second stretching portion 32, a rotating shaft 33, a contact portion 34, and a latch 35. The first stretched portion 31 and the second stretched portion 32 are connected to both sides of the rotating shaft 33. That is, the first stretched portion 31 and the second stretched portion 32 are connected so as to be continuous, and the rotating shaft 33 is provided so as to project from the intermediate portion on both sides. Further, a groove having a contact portion 34 inclined from the rotation shaft 33 toward the latch 35 is provided in the intermediate portion of the second stretched portion 32.

ロック部材３０は、ハウジング１０に組み込まれる。具体的には、ロック部材３０は、ハウジング１０に設けられた収容溝１１内に配置される。ロック部材３０は、ハウジング１０の収容溝１１内において回転軸３３を中心軸として回動可能に設置される。すなわち、回転軸３３を中心軸として、第１延伸部３１が押し下げられたときにはラッチ３５が押し上げられ、第１延伸部３１が押し上げられたときにはラッチ３５が押し下げられる。 The lock member 30 is incorporated in the housing 10. Specifically, the lock member 30 is arranged in the accommodating groove 11 provided in the housing 10. The lock member 30 is rotatably installed in the accommodating groove 11 of the housing 10 with the rotation shaft 33 as the central axis. That is, with the rotating shaft 33 as the central axis, the latch 35 is pushed up when the first stretched portion 31 is pushed down, and the latch 35 is pushed down when the first stretched portion 31 is pushed up.

リリース部材４０は、ハンドル部４１、格納溝４２、位置規制部４３及び操作突起部４４を備える。位置規制部４３は、ロック部材３０と組み合わされたハウジング１０を収納するように筒形状とされる。本実施の形態では、ハウジング１０の外形が矩形とされているので、位置規制部４３はハウジング１０に嵌合する矩形筒状とされている。 The release member 40 includes a handle portion 41, a storage groove 42, a position restricting portion 43, and an operation protrusion portion 44. The position regulating portion 43 has a tubular shape so as to accommodate the housing 10 combined with the lock member 30. In the present embodiment, since the outer shape of the housing 10 is rectangular, the position restricting portion 43 has a rectangular tubular shape that fits into the housing 10.

ハンドル部４１は、位置規制部４３の後端部から延伸して設けられる。ハンドル部４１は、相手側であるアダプタやモジュールに光コネクタ１００を着脱させる際にユーザが操作する部分として機能する。ハンドル部４１を用いてリリース部材４０をハウジング１０に対して相対的に移動させることによって、ハウジング１０をリリース部材４０に押し込んだロック状態（図３）とハウジング１０をリリース部材４０に引き出したリリース状態（図４）に選択的に切換えることができる。 The handle portion 41 is provided so as to extend from the rear end portion of the position restricting portion 43. The handle portion 41 functions as a portion operated by the user when attaching / detaching the optical connector 100 to / from the adapter or module on the other side. By moving the release member 40 relative to the housing 10 using the handle portion 41, a locked state in which the housing 10 is pushed into the release member 40 (FIG. 3) and a released state in which the housing 10 is pulled out to the release member 40. It can be selectively switched to (FIG. 4).

ハンドル部４１の内部は中空状の格納溝４２とされている。中空状の格納溝４２には、ハウジング１０とリリース部材４０とを摺動させてロック状態（図３）からリリース状態（図４）に遷移させた際にロック部材３０の当接部３４と当接する操作突起部４４が設けられる。 The inside of the handle portion 41 is a hollow storage groove 42. The hollow storage groove 42 is in contact with the contact portion 34 of the lock member 30 when the housing 10 and the release member 40 are slid to transition from the locked state (FIG. 3) to the released state (FIG. 4). An operating protrusion 44 in contact is provided.

図２の矢印で示す方向にリリース部材４０がハウジング１０に装着された状態においてロック状態（図３）となる位置までリリース部材４０を移動させる過程では、操作突起部４４がラッチ３５を押圧し、回転軸３３を軸としてラッチ３５から時計回り方向に回動されて下へ若干移動された後、操作突起部４４がラッチ３５を通過して当接部３４に収容される。同時に、ハンドル部４１の中空状の格納溝４２を構成する突起部４１１が第１延伸部３１を押圧し、ロック部材３０が再び回転軸３３を軸として反時計回り方向に回動されて図３に示すロック状態となる。 In the process of moving the release member 40 to the locked state (FIG. 3) when the release member 40 is mounted on the housing 10 in the direction indicated by the arrow in FIG. 2, the operating protrusion 44 presses the latch 35. After being rotated clockwise from the latch 35 with the rotation shaft 33 as an axis and slightly moved downward, the operation protrusion 44 passes through the latch 35 and is accommodated in the contact portion 34. At the same time, the protrusion 411 constituting the hollow storage groove 42 of the handle portion 41 presses the first stretched portion 31, and the lock member 30 is rotated again in the counterclockwise direction about the rotation shaft 33 in FIG. 3. It becomes the locked state shown in.

すなわち、光コネクタ１００を相手側のアダプタやモジュールに装着する際に、このような手順によって、アダプタやモジュールの側に設けられた係止部にラッチ３５を係止させてロック状態（図３）にさせつつ、光コネクタ１００をアダプタやモジュールに装着することができる。 That is, when the optical connector 100 is attached to the adapter or module on the other side, the latch 35 is locked to the locking portion provided on the side of the adapter or module by such a procedure (FIG. 3). The optical connector 100 can be attached to an adapter or a module.

一方、リリース部材４０をロック状態（図３）からリリース状態（図４）に遷移させるときは、リリース部材４０を第１延伸部３１側（図３の左方向）に引っ張って移動させると、操作突起部４４がロック部材３０の当接部３４に当接され、回転軸３３を軸としてロック部材３０を時計回り方向に回動させる。このとき、リリース部材４０が左側に移動する関係で、突起部４１１が第１延伸部３１に当接されなくなるため、回転軸３３を軸としてロック部材３０を回動させることができる。リリース部材４０を継続して移動させると、ラッチ３５が収容溝１１内に収容されてロック状態が解除されてリリース状態（図４）となる。このとき、第１延伸部３１は、リリース部材４０の格納溝４２内に収容される。 On the other hand, when the release member 40 is transitioned from the locked state (FIG. 3) to the released state (FIG. 4), the release member 40 is operated by pulling and moving the release member 40 toward the first stretched portion 31 (left direction in FIG. 3). The protrusion 44 is brought into contact with the contact portion 34 of the lock member 30, and the lock member 30 is rotated clockwise around the rotation shaft 33. At this time, since the release member 40 moves to the left side, the protrusion 411 does not come into contact with the first stretched portion 31, so that the lock member 30 can be rotated around the rotation shaft 33. When the release member 40 is continuously moved, the latch 35 is accommodated in the accommodating groove 11 and the locked state is released to enter the release state (FIG. 4). At this time, the first stretched portion 31 is housed in the storage groove 42 of the release member 40.

また、ロック状態が解除されてリリース状態となったとき、さらに継続してリリース部材４０を引っ張って移動させる（図面の左側に移動させる）ことで、光コネクタ１００をアダプタやモジュールから取り外すことができる。 Further, when the locked state is released and the released state is reached, the optical connector 100 can be removed from the adapter or module by continuously pulling and moving the release member 40 (moving it to the left side of the drawing). ..

以上のように、ロック部材３０を弾性変形させることなく、回転軸３３を回転軸としてラッチ３５を回動させることによってロック状態とリリース状態とを選択的に遷移させることができる光コネクタ１００とすることができる。 As described above, the optical connector 100 is capable of selectively transitioning between the locked state and the released state by rotating the latch 35 with the rotating shaft 33 as the rotating shaft without elastically deforming the lock member 30. be able to.

なお、光コネクタ１００の構成は適宜変更してもよい。例えば、ロック部材３０における当接部３４とリリース部材４０における操作突起部４４との配置を変更して、回転軸３３を回転軸としてリリース状態において第１延伸部３１を下側から押し上げてロック部材３０を回動させるように当接部３４と操作突起部４４を設けてもよい。また、ロック部材３０における第１延伸部３１とリリース部材４０における突起部４１１との配置を変更して、回転軸３３を回転軸としてロック状態において第２延伸部３２を下側から押し上げるようにロック部材３０を回動させるように第１延伸部３１と突起部４１１を設けてもよい。さらに、回転軸３３を回転軸としてラッチ３５を回動させることによってロック状態とリリース状態とを選択的に遷移できるような構成であれば他の構成を採用してもよい。 The configuration of the optical connector 100 may be changed as appropriate. For example, the arrangement of the contact portion 34 in the lock member 30 and the operation protrusion 44 in the release member 40 is changed, and the first extension portion 31 is pushed up from below in the released state with the rotation shaft 33 as the rotation shaft to push up the lock member. The contact portion 34 and the operation protrusion portion 44 may be provided so as to rotate the 30. Further, the arrangement of the first stretched portion 31 in the lock member 30 and the protrusion 411 in the release member 40 is changed so that the second stretched portion 32 is pushed up from below in the locked state with the rotating shaft 33 as the rotating shaft. The first stretched portion 31 and the protruding portion 411 may be provided so as to rotate the member 30. Further, another configuration may be adopted as long as the configuration can selectively transition between the locked state and the released state by rotating the latch 35 with the rotating shaft 33 as the rotating shaft.

また、例えば、光コネクタ１００では、フェルール２０を２つ並べて配置した構成としたが、フェルール２０の数を変更してもよいし、配置を変更してもよい。また、例えば、光コネクタ１００では、収容溝１１及びロック部材３０を２つのフェルール２０の間に配置したが、１つのフェルール２０の横に配置してもよいし、他の位置に配置してもよい。 Further, for example, in the optical connector 100, two ferrules 20 are arranged side by side, but the number of ferrules 20 may be changed or the arrangement may be changed. Further, for example, in the optical connector 100, the accommodating groove 11 and the lock member 30 are arranged between the two ferrules 20, but they may be arranged next to one ferrule 20 or at other positions. good.

また、本実施の形態ではフェルール２０に光ファイバを装着する光コネクタ１００としたが、本発明の適用範囲は光ファイバに対するコネクタに限定されるものではない。例えば、フェルール２０に電気的な配線を装着するコネクタとしてもよい。 Further, in the present embodiment, the optical connector 100 in which the optical fiber is mounted on the ferrule 20 is used, but the scope of application of the present invention is not limited to the connector for the optical fiber. For example, it may be a connector for attaching electrical wiring to the ferrule 20.
