Further, a female screw 46 is formed at the base end of the hole portion of the holder 45, and is screwed to the male screw 48 at the tip of the substantially cylindrical water cooling holder 47.
The water cooling holder 47 is provided with a shaft center hole 49 having a stepped portion 49A closer to the tip and forming a tip small diameter hole portion 49B.

挿入ユニット構造体29が基端から挿入されるユニット保持筒50が、上記水冷ホルダ47の基端から挿入、保持されている。つまり、ユニット保持筒50は水冷ホルダ47の基端から挿入されて、ユニット保持筒50の先端部は、水冷ホルダ47の先端の小径孔部49Bに密嵌状に挿入され、(図示省略の)シール材にて、密封され、冷却水の先端側への洩れを防止している。そして、既述の冷却水入口継手35と冷却水出口継手36が取着されるラジアル方向孔部33A,33Aが軸心L1 方向に位置をずらせて、基端と先端寄りに、上記水冷ホルダ47に形成される。さらに、ユニット保持筒50の外周面と、軸心孔49との間には、円筒型水路部33Bが形成され、上記ラジアル方向孔部33A,33Aと円筒型水路部33Bとを連通して、冷却水路33を構成する。これによって、挿入ユニット構造体29の軸心方向中央部位の発熱しやすい部位を、薄肉としたユニット保持筒50を介して冷却できる。 A unit holding cylinder 50 into which the insertion unit structure 29 is inserted from the base end is inserted and held from the base end of the water cooling holder 47. That is, the unit holding cylinder 50 is inserted from the base end of the water cooling holder 47, and the distal end portion of the unit holding cylinder 50 is inserted into the small diameter hole portion 49B at the distal end of the water cooling holder 47 in a close fitting manner (not shown). Sealed with a sealing material to prevent leakage of cooling water to the tip side. The radial hole 33A which cooling water outlet fitting 36 and the cooling water inlet fitting 35 described above is attached, 33A is shifted to the position in the axial L 1 direction, the proximal and distal ends toward said water-cooled holder Formed in 47. Further, a cylindrical water channel part 33B is formed between the outer peripheral surface of the unit holding cylinder 50 and the axial hole 49, and the radial hole parts 33A, 33A and the cylindrical water channel part 33B are communicated with each other. A cooling water channel 33 is formed. As a result, the heat generating portion of the central portion in the axial center direction of the insertion unit structure 29 can be cooled via the thin unit holding cylinder 50.

ところで、51は内部保護用内窓ガラスであり、ユニット保持筒50の孔部先端に固着される。この内窓ガラス51は、前記石英チップ30の大径出射端面30Bに近接状に対面する。
従って、先端窓ホルダ45の着脱にかかわらず、防塵が最も要求される大径出射端面30Bに近接して、内窓ガラス51が対面する。このように内窓ガラス51は、ユニット保持筒50に固着され、ユニット保持筒50は先端側が密封された状態として、閉鎖され、大径出射端面30Bは清浄に維持できる。
Incidentally, reference numeral 51 denotes an internal window glass for internal protection, which is fixed to the tip of the hole of the unit holding cylinder 50. The inner window glass 51 faces the large-diameter emitting end face 30B of the quartz chip 30 in a close proximity.
Therefore, regardless of whether the tip window holder 45 is attached or detached, the inner window glass 51 faces in the vicinity of the large-diameter emitting end face 30B where dust protection is most required. Thus, the inner window glass 51 is fixed to the unit holding cylinder 50, the unit holding cylinder 50 is closed in a state where the tip end side is sealed, and the large-diameter emission end face 30B can be kept clean.

なお、ユニット保持筒50の基端大径部には雄ネジ52を設け、カップリングナット53を着脱自在に螺着し、挿入ユニット構造体29の基端に(図示省略のビス等にて固着された)ブラケット固着用部材54が、固着されている。
また、ネジ46, 48にて取着された先端窓ホルダ45の内端面45Aと、水冷ホルダ47の先端面47Aとの間にギャップを形成して、内窓ガラス51と先端窓ガラス44の間に空室部55を設ける。
The unit holding cylinder 50 is provided with a male screw 52 at the base end large diameter portion, and a coupling nut 53 is detachably screwed to the base end of the insertion unit structure 29 (fixed with a screw or the like not shown). The bracket fixing member 54 is fixed.
Further, a gap is formed between the inner end surface 45A of the front end window holder 45 attached by screws 46 and 48 and the front end surface 47A of the water cooling holder 47, so that the space between the inner window glass 51 and the front end window glass 44 is increased. A vacant part 55 is provided in the room.

パージエア入口継手37は水冷ホルダ47の外周の一部に付設され、パージエア流路34は、この継手37から上記空室部55とを連通連結するように、水冷ホルダ47に設けられる。
先端窓ガラス44は、窓ホルダ45の孔部に、先端側から嵌め込まれて、エア噴出小溝を複数ずつ有するエア噴出リング56・押えリング57を順次取着し、空室部55に一旦導入されたパージエアは、エア噴出リング56・押えリング57等のエア噴出小溝(小孔)等のパージエア噴出部Mを介して、先端窓ガラス44の先端側外面44Aの防塵を行う。このとき、空室部55内はパージエアによる陽圧状態となって、先端側(外部)から粉塵が侵入せず、内窓ガラス51の外面、及び、先端窓ガラス44の内面も、常に清浄に保たれる。
The purge air inlet joint 37 is attached to a part of the outer periphery of the water cooling holder 47, and the purge air flow path 34 is provided in the water cooling holder 47 so as to communicate and connect the empty chamber portion 55 from the joint 37.
The front window glass 44 is fitted into the hole of the window holder 45 from the front end side, and the air ejection ring 56 and the holding ring 57 each having a plurality of air ejection small grooves are sequentially attached, and once introduced into the empty space 55. The purge air protects the front end side outer surface 44A of the front end window glass 44 through a purge air ejection portion M such as an air ejection small groove (small hole) such as the air ejection ring 56 and the presser ring 57. At this time, the inside of the vacant chamber 55 is in a positive pressure state by purge air, dust does not enter from the front end side (external), and the outer surface of the inner window glass 51 and the inner surface of the front window glass 44 are always clean. Kept.

次に、図6に於て、(図1の)挿入孔4への挿入深さを調整するための円環状調整リング10の当接面10Aの軸心方向位置は、内部のレーザ伝送用光ファイバ28の出射端側の焦点位置N───即ち、図6では光ファイバ端面28Aに相当する位置───に略一致させる。言い換えると、石英チップ30の細径端面30Aの位置と、調整リング10の当接面10Aの軸心方向位置とを、略一致させて、外観的に焦点位置Nが判断可能として、光学部品が接続される部品(例えば、図1,図14の光学ヘッド部材2)等の設計が容易となる。   Next, in FIG. 6, the axial position of the contact surface 10A of the annular adjustment ring 10 for adjusting the insertion depth into the insertion hole 4 (of FIG. 1) is the internal laser transmission light. The focal position N on the emission end side of the fiber 28, that is, the position corresponding to the optical fiber end face 28A in FIG. In other words, the position of the small diameter end surface 30A of the quartz chip 30 and the axial direction position of the contact surface 10A of the adjustment ring 10 are substantially matched so that the focal position N can be visually determined, and the optical component can be determined. Design of components to be connected (for example, the optical head member 2 in FIGS. 1 and 14) and the like becomes easy.

また、図6と図7に示すように、以下の特徴的構成も具備している。即ち、コネクタ軸心L1 に沿って挿入された光ファイバ28の端面28Aに、先端側に拡径する石英チップ30の細径端面30Aを融着一体化し、該石英チップ30の大径出射端面30Bにおけるエネルギ密度を低下させると共に、上記光ファイバ28の上記端面28Aを出射端側焦点位置Nに略一致させ、さらに、上記石英チップ30の大径出射端面30Bに近接して内部保護用内窓ガラス51を設け、かつ、先端寄りに先端窓ガラス44を配設し、該先端窓ガラス44の内面と上記焦点位置Nまでの軸心方向距離L44が、上記内窓ガラス51の内面と上記焦点位置Nまでの軸心方向距離L51の 1.5倍〜10倍の範囲に設定している。 Further, as shown in FIGS. 6 and 7, the following characteristic configuration is also provided. That is, the end surface 28A of the connector axis L 1 is inserted along the optical fiber 28, a small-diameter end surface 30A of the quartz chip 30 whose diameter increases distally fused integrated large-diameter exit end face of the quartz chip 30 While reducing the energy density at 30B, the end face 28A of the optical fiber 28 is made to substantially coincide with the output end side focal position N, and the inner window for internal protection is provided close to the large-diameter exit end face 30B of the quartz chip 30. A glass 51 is provided, and a tip window glass 44 is disposed near the tip, and the axial distance L 44 between the inner surface of the tip window glass 44 and the focal position N is such that the inner window glass 51 and the inner window glass 51 The axial center direction distance L 51 to the focal position N is set in the range of 1.5 to 10 times.

このように、 1.5・L51≦L44≦10・L51に設定することで、清浄なパージエアに接している内窓ガラス51から、外気に触れる先端窓ガラス44を十分に離間させることとなり、この先端窓ガラス44の伝送レーザのエネルギ密度を、約1/2〜1/ 100に低下させ、外気の塵が外面44Aに付着して焼けて先端窓ガラス44を焼損させることを防止し、寿命を延ばし得る利点があり、さらに、清浄なエアを流すための前述の空室部55を十分に形成可能となる。
なお、L44< 1.5・L51の場合は、外面44Aのエネルギ密度が十分に低くできず、先端窓ガラス44の焼損及び寿命短縮の問題を生ずる。逆に、10・L51<L44の場合は、コネクタ1の軸心方向寸法が過大となり、かつ、先端窓ガラス44の外径寸法が過大となり、コネクタ1のコンパクト化が難しくなる。
Thus, by setting 1.5 · L 51 ≦ L 44 ≦ 10 · L 51 , the tip window glass 44 that touches the outside air is sufficiently separated from the inner window glass 51 that is in contact with clean purge air. The energy density of the transmission laser of this front window glass 44 is reduced to about 1/2 to 1/100, and dust from outside air adheres to the outer surface 44A and is burnt to prevent the front window glass 44 from being burned, and the service life. In addition, it is possible to sufficiently form the above-described vacant portion 55 for flowing clean air.
In the case of L 44 <1.5 · L 51 , the energy density of the outer surface 44A cannot be made sufficiently low, causing the problem of burning the tip window glass 44 and shortening the life. On the other hand, when 10 · L 51 <L 44 , the axial direction dimension of the connector 1 is excessive, and the outer diameter of the front window glass 44 is excessive, making it difficult to make the connector 1 compact.

次に、図8に示した他の実施の形態では、図6,図7にて説明した実施の形態と、以下の点で相違している。即ち、挿入ユニット構造体29の構成を用いずに、光ファイバ28、及び、それに付属の最少の部品を、直接的に、コネクタ本体11内へ挿入する構造である。さらに、水冷ホルダ47が2分割結合構造として、基端水冷ホルダ47Bと先端水冷ホルダ47Fを別々に製作して後に、連結一体化した構造である。
図8に於て、図6(図7)と同一符号は同様の構成を示し、繰り返しての重複説明を省略する。
Next, the other embodiment shown in FIG. 8 differs from the embodiment described with reference to FIGS. 6 and 7 in the following points. That is, without using the configuration of the insertion unit structure 29, the optical fiber 28 and the minimum components attached thereto are directly inserted into the connector main body 11. Further, the water-cooling holder 47 has a two-part coupling structure in which the proximal-end water-cooling holder 47B and the distal-end water-cooling holder 47F are separately manufactured and then connected and integrated.
In FIG. 8, the same reference numerals as those in FIG. 6 (FIG. 7) denote the same components, and repeated description will be omitted.

次に、図9〜図11に示す別の実施の形態について説明する。図6と図7にて述べた実施の形態との相違点は、コネクタ本体11と水冷ホルダ47の先端部位、及び、先端防塵ヘッド65(先端窓ホルダ45)の形状と構造、さらに、それ等の内部に付設される部品等にある。
具体的にそれ等の相違点から説明すると、まず、コネクタ先端に、開閉自在な防塵用シャッタ機構Sを具備している。このシャッタ機構Sは、コネクタ先端から突出状に円錐コイルバネや通常のコイルバネ又は板バネ等の(図10に示した)弾発部材58にて付勢された円筒状感知筒体59と、シャッタ本体60と、上記感知筒体59の軸心方向往復動をシャッタ本体60の開閉作動に変換する切換手段61とを、備え、前述の挿入孔4への非挿入状態では、上記弾発部材58の弾発力が上記切換手段61を介してシャッタ本体60へ伝達されて、この弾発力によって、シャッタ本体60が閉状態を保つ。なお、本発明に於て、閉状態とは、シャッタ本体60の絞り孔62が完全に閉じた状態を含むが、それ以外に、絞りの機構上から微小な絞り孔62が存在している状態も含むものとする。
Next, another embodiment shown in FIGS. 9 to 11 will be described. The difference between the embodiment described with reference to FIGS. 6 and 7 is that the connector body 11 and the tip portion of the water cooling holder 47, the shape and structure of the tip dustproof head 65 (tip window holder 45), and the like. It is in the parts attached to the inside.
Specifically, the difference will be described. First, a dust-proof shutter mechanism S that can be opened and closed is provided at the tip of the connector. The shutter mechanism S includes a cylindrical sensing cylinder 59 urged by a resilient member 58 (shown in FIG. 10) such as a conical coil spring, a normal coil spring, or a leaf spring protruding from the tip of the connector, and a shutter body. 60, and switching means 61 that converts the reciprocating motion of the sensing cylinder 59 in the axial direction into the opening / closing operation of the shutter body 60. In the non-inserted state of the insertion hole 4, the elastic member 58 is The elastic force is transmitted to the shutter main body 60 via the switching means 61, and the shutter main body 60 is kept closed by this elastic force. In the present invention, the closed state includes a state in which the aperture hole 62 of the shutter body 60 is completely closed, but in addition, a state in which the minute aperture hole 62 exists from the viewpoint of the aperture mechanism. Shall also be included.

さらに具体的には、図6と図9とを比較すれば明らかなように、図6の先端窓ガラス44を省略して、代わりに、シャッタ本体60を内部保護用内窓ガラス51に近接状に配設している。また、シャッタ本体60は、多数の開閉羽根60Aと、これを包囲するリング体60Bと、リング体60Bの外周面からラジアル外方へ突出して開閉羽根60Aの絞り度合を変更させる作動ピン60Cとを、有する。図10の平面断面図のように、切換手段61は、感知筒体59の円筒壁に形成された斜め方向カム溝63と、上記作動ピン60Cのこのカム溝63への挿入部分をもって、構成される。   More specifically, as apparent from a comparison between FIG. 6 and FIG. 9, the front window glass 44 of FIG. 6 is omitted, and instead, the shutter body 60 is placed close to the inner window glass 51 for internal protection. It is arranged. The shutter body 60 includes a large number of opening / closing blades 60A, a ring body 60B that surrounds the opening / closing blades 60A, and an operating pin 60C that protrudes radially outward from the outer peripheral surface of the ring body 60B to change the degree of aperture of the opening / closing blades 60A. Have. As shown in the plan sectional view of FIG. 10, the switching means 61 is composed of an oblique cam groove 63 formed on the cylindrical wall of the sensing cylinder 59 and a portion where the operating pin 60C is inserted into the cam groove 63. The

感知筒体59は、図10に於て、2点鎖線にて示す突出状態(自由状態)と、実線にて示した中間状態と、図9に実線にて示す後退状態に、切換わる。図2と図14に於て、相手部材Zの挿入孔4の内部に、段付面を形成して当り部64とする。コネクタ先端が、図10の2点鎖線で示すように感知筒体59が大きく突出状の状態で、取付用相手部材Zの挿入孔4へ挿入されてゆく際に、この挿入孔4の内部の当り部64に筒体59の先端面が接触し、弾発部材58に抗して、図10の実線を経て、さらに、図9のように、筒体59は後退し、これに連動するように切換手段61によってシャッタ本体60の開閉羽根60Aは、挿入孔4内部で開く。   In FIG. 10, the sensing cylinder 59 is switched between a protruding state (free state) indicated by a two-dot chain line, an intermediate state indicated by a solid line, and a retracted state indicated by a solid line in FIG. 2 and 14, a stepped surface is formed inside the insertion hole 4 of the mating member Z to form a contact portion 64. When the tip of the connector is inserted into the insertion hole 4 of the mounting mating member Z with the sensing cylinder 59 projecting greatly as shown by the two-dot chain line in FIG. The front end surface of the cylindrical body 59 comes into contact with the contact portion 64, resists the elastic member 58, passes through the solid line in FIG. 10, and the cylindrical body 59 moves backward as shown in FIG. The switching means 61 opens the opening / closing blade 60A of the shutter body 60 inside the insertion hole 4.

そして、パージエア入口継手37に連通するパージエア流路34の先端は、水冷ホルダ47の先端面であって、シャッタ機構Sの近傍に開口している。即ち、パージエア噴出部66をコネクタ本体11の先端側に配設して、シャッタ機構Sに吹き付けて流し、シャッタ本体60の防塵を行う。   The distal end of the purge air flow path 34 communicating with the purge air inlet joint 37 is the distal end surface of the water cooling holder 47 and opens near the shutter mechanism S. That is, the purge air ejection portion 66 is disposed on the distal end side of the connector main body 11 and blows and flows to the shutter mechanism S to prevent the shutter main body 60 from dust.

内部保護用内窓ガラス51の内面は、図6の実施の形態で説明したようにユニット保持筒50にて包囲されて十分清浄に維持され、他方、内窓ガラス51の外面は、シャッタ機構S及びパージエア噴出部66から噴出するパージエアによって、十分に防塵される構造である。
なお、図9に於て、図6と同一の符号は同様の構成を示し、重複説明を省略する。
As described in the embodiment of FIG. 6, the inner surface of the inner window glass 51 for internal protection is surrounded by the unit holding cylinder 50 and is kept sufficiently clean, while the outer surface of the inner window glass 51 is the shutter mechanism S. In addition, the structure is sufficiently dust-proof by the purge air ejected from the purge air ejection section 66.
In FIG. 9, the same reference numerals as those in FIG.

次に、図12に示す、さらに他の実施の形態は、図8の実施の形態と、図9の実施の形態の先端部位とを、結合した構成であり、図8と図10と同一符号は、同様の構成であるので、重複説明を省略する。作用効果についても、図8と図10と同様である。   Next, still another embodiment shown in FIG. 12 is a configuration in which the embodiment of FIG. 8 and the tip portion of the embodiment of FIG. 9 are combined, and the same reference numerals as in FIGS. Since the configuration is the same, redundant description is omitted. The effects are also the same as in FIGS.

ところで、図4〜図12に於て、図13〜図17、及び、図1〜図3に示したクランプ手段Cによって掴持されるクランプ部68が、コネクタ本体11の軸心方向中間部位に、やや小径円周面をもって、設けられている。そして、図13〜図17に基づいて、コネクタ取付構造、及び、その作用と操作手順等について、以下説明する。 4 to 12, the clamp portion 68 held by the clamp means C shown in FIGS. 13 to 17 and FIGS. It is provided with a slightly small-diameter circumferential surface. Based on FIG. 13 to FIG. 17 , the connector mounting structure, and its operation and operation procedure will be described below.

図15の破線から実線にて示したように、遠隔操作用ロボットRのハンド部23にて、コネクタ1の把持部Dを掴持する。次に、図13に示すように、孔軸心L4 と直交する横方向Eから、掴持したコネクタ1を取付用相手部材Zへ送り込み、遠隔操作可能なクランプ手段Cにて、受取って保持する。このとき、孔軸心L4 とコネクタ軸心L1 とが一致する(図14参照)。
また、クランプ手段Cにて保持したコネクタ1を、孔軸心L4 に沿って、矢印Aのように、直線往復動手段Kにて、送りを与える(降下させる)。
As indicated by the solid line from the broken line in FIG. 15, the grip part D of the connector 1 is gripped by the hand part 23 of the robot R for remote operation. Next, as shown in FIG. 13, from the lateral direction E perpendicular to the hole axis L 4 , the gripped connector 1 is sent to the mounting counterpart member Z, and is received and held by the remotely operable clamp means C. To do. At this time, the hole axis L 4 and the connector axis L 1 coincide (see FIG. 14).
Further, the connector 1 held by the clamping means C is fed (lowered) by the linear reciprocating means K as indicated by the arrow A along the hole axis L 4 .

クランプ手段Cは、横方向Eから送り込まれてくるコネクタ1の外周面の一部を、弾発的に拡開変形して受け取る仮保持用弾発挾持体69を有する。具体的には、往復移動台17から2本の線状バネ69A,69Aを矢印Eと反対方向へ突設して仮保持用弾発挾持体69とし、かつ、この線状バネ69A,69Aは、図16の矢印E方向から送り込まれてくる円形断面のコネクタ本体11の外周面にて、開脚するように誘導する先端拡幅誘導部70を備え、さらに、略半円弧状の最終保持部71が連続して形成されて、往復移動台17から水平状に突設され、例えば、コネクタ1のクランプ部68の上端縁に、弾発的に外嵌状として、挾持する。なお、弾発挾持体69を複数個、上下に所定間隔をもって、配設して、コネクタ軸心L1 に相違する複数の部位にて、弾発的にコネクタ1を仮保持するも、安定姿勢を確保して望ましい。
なお、線状バネ69A,69Aを、帯状の板バネをもって構成することも、自由である。
The clamping means C has a temporary holding bullet-carrying body 69 for receiving a part of the outer peripheral surface of the connector 1 fed from the lateral direction E after being elastically expanded and deformed. Specifically, two linear springs 69A and 69A are projected from the reciprocating moving base 17 in the direction opposite to the arrow E to form a temporary holding bullet holder 69, and these linear springs 69A and 69A are 16 is provided with a tip widening guiding portion 70 for guiding the outer peripheral surface of the connector body 11 having a circular cross section fed from the direction of arrow E in FIG. Are formed in a continuous manner and project horizontally from the reciprocating platform 17 and, for example, are elastically fitted to the upper end edge of the clamp portion 68 of the connector 1 as an external fitting. It should be noted that a plurality of the elastic holding bodies 69 are arranged at predetermined intervals in the vertical direction, and the connector 1 is temporarily held temporarily at a plurality of portions different from the connector axis L 1. It is desirable to ensure.
Note that the linear springs 69A and 69A can be configured with band-shaped plate springs.

そして、クランプ手段Cは、このような仮保持用の弾発挾持体69の他に、さらに、本来のクランプ作用をなすための掴持具72を備えている。つまり、仮保持は、コネクタ自重を一旦、取付用相手部材Z側へ預け、次工程にて、遠隔操作によるクランプ手段Cの作動を、容易とする。   The clamping means C is provided with a gripping tool 72 for performing an original clamping action in addition to the temporary holding bullet holding body 69. That is, the temporary holding temporarily deposits the weight of the connector to the mounting mating member Z side, and facilitates the operation of the clamping means C by remote operation in the next step.

掴持具72は、往復移動台17に固着された(固定側の)半円弧体18と、この半円弧体18にピン19にて、図17の破線と実線のように開閉(揺動)自在に枢結された可動側半円弧体20と、両半円弧体18, 20を閉状態に固定するボルト・ナット結合21A等から、構成される。両半円弧体18, 20の各自由端には、突片18A, 20Aが突設され、一方の突片18Aには、ボルト・ナット結合21Aのボルトの基端がピン73にて、図17に実線と破線のように揺動可能に枢着され、他方、他方の突片20Aには、ボルト・ナット結合21Aのボルトが差込可能な係止溝74が形成される。このボルト・ナット結合21Aのナット75は、遠隔操作用ロボットRのハンド部23にて容易に回転可能であり、螺進退にて、両半円弧体18, 20のロックとアンロックを行い得る。   The gripping tool 72 is opened and closed (oscillated) as indicated by the broken line and the solid line in FIG. The movable side semicircular arc body 20 is pivotally connected freely, and a bolt / nut coupling 21A for fixing both the semicircular arc bodies 18, 20 in a closed state. Projection pieces 18A and 20A project from the free ends of both semicircular arc bodies 18 and 20, and the base end of the bolt of the bolt / nut coupling 21A is pin 73 at one projection piece 18A. On the other hand, a locking groove 74 into which the bolt of the bolt / nut coupling 21A can be inserted is formed on the other projecting piece 20A. The nut 75 of the bolt / nut coupling 21A can be easily rotated by the hand portion 23 of the remote-control robot R, and both the semicircular arc bodies 18 and 20 can be locked and unlocked by screwing back and forth.

直線往復動手段Kについて説明すると、基枠(ステージ)3の柱状部材14にスライド用ガイドレール15,15が固設され、このガイドレール15, 15に沿って誘導案内可能としてスライドガイド16, 16が取付けられ、さらに、往復移動台17がスライドガイド16に固設されている。また、スライドガイド16にロックレバー76を付設するのも好ましい。つまり、ロックレバー76にて操作されるロック機構を付加すれば、正確な上下高さ位置に、スライドガイド16を固定可能となる。このロックレバー76の開閉も上記ハンド部23にて遠隔操作する。   The linear reciprocating means K will be described. Slide guide rails 15 and 15 are fixed to the columnar member 14 of the base frame (stage) 3, and the slide guides 16 and 16 can be guided along the guide rails 15 and 15. The reciprocating table 17 is fixed to the slide guide 16. It is also preferable to attach a lock lever 76 to the slide guide 16. That is, if a lock mechanism operated by the lock lever 76 is added, the slide guide 16 can be fixed at an accurate vertical height position. The opening and closing of the lock lever 76 is also remotely operated by the hand unit 23.

さらに、柱状部材14の上端にギヤボックス77を設け、このギヤボックス77から、スクリューシャフト78を垂設して、往復移動台17に付設のナット部材と、螺合させて、送りネジ機構を構成する。79は、送りネジ機構を作動するハンドルであって、遠隔操作用ハンド部23にて、このハンドル79を回転させて、往復移動台17を昇降させ、もって、矢印A及びその反対方向に、孔軸心L4 に沿って、コネクタ1を直線往復動(昇降)させる。
なお、ギヤボックス77を設けることによって、鉛直状スクリューシャフト78の回転を、ハンドル79の水平状軸心L79廻りの回転に変換したので、ハンド部23により遠隔操作が容易となる利点がある。
Further, a gear box 77 is provided at the upper end of the columnar member 14, and a screw shaft 78 is suspended from the gear box 77, and screwed with a nut member attached to the reciprocating table 17 to constitute a feed screw mechanism. To do. Reference numeral 79 denotes a handle for operating the feed screw mechanism. The handle 79 is rotated by the remote operation hand unit 23 to raise and lower the reciprocating table 17 so that a hole is formed in the arrow A and the opposite direction.

The mounting plate piece 39 is disposed in the vicinity of the grip portion D in the axial direction, and the attachment region J to which the relay pipe joints 38, 38, 38 are attached has an axial direction. When viewed from the side, the hand portion 23 is disposed 180 ° opposite to the approaching side of the hand portion 23, so that the problem of interference when the hand portion 23 approaches the grip portion D is eliminated. Moreover, in the normal direction position to the connector axis L 1 around, it can accommodate the relay pipe fittings 38, 38, 38.

また、上記把持部Dの上記二平面22,22の間隔寸法W22の帯状領域42内に、上記中継管継手38,38,38が配設されているので、(図5に示したように、)ハンド部23が、把持部Dへの接近方向から反対側まで突出したとしても、中継管継手38が干渉することが全くない。 Further, the band-like region 42 of the spacing dimension W 22 of the two planes 22, 22 of the grip portion D, since the relay pipe fittings 38, 38, 38 are arranged, as shown in (FIG. 5 )) Even if the hand portion 23 protrudes from the approaching direction to the gripping portion D to the opposite side, the relay pipe joint 38 does not interfere at all.

また、先端に開閉自在な防塵用シャッタ機構Sを付設したので、コネクタ先端側の防塵が十分に行い得て、内窓ガラス51等のハイパワーレーザ光による焼損を防止できる。
Further, the end surface 28A of the laser transmission optical fiber 28 inserted along the base end side to a connector axis L 1, the small-diameter end surface 30A of the quartz chip 30 whose diameter increases distally fused integrated quartz Since the energy density in the large-diameter exit end face 30B of the chip 30 is reduced, even if high power energy is sent, the exit end face 30B is less susceptible to burning even if dust or dirt adheres to it. It will be a lifetime.
In addition, since the dust-proof shutter mechanism S that can be freely opened and closed is provided at the tip, dust can be sufficiently protected at the tip of the connector, and burning of the inner window glass 51 and the like by high-power laser light can be prevented.

また、上記シャッタ機構Sは、先端から突出状に弾発部材58にて付勢されると共に、取付用相手部材Zの挿入孔4へ挿入されてゆく際に該挿入孔4の内部の当り部64に接触すると上記弾発部材58に抗して後退する感知筒体59と、シャッタ本体60と、上記感知筒体59の軸心方向往復動を上記シャッタ本体60の開閉作動に変換する切換手段61とを、備え、上記挿入孔4への非挿入状態では、上記シャッタ本体60が閉状態を保つように構成されているので、非挿入状態に於ける防塵が十分に行われ、しかも、挿入状態(接続完了状態)では、自動的にレーザ光の通過可能状態となる。従って、遠隔操作用として好適なものといえる。   The shutter mechanism S is urged by the resilient member 58 so as to protrude from the tip, and when the shutter mechanism S is inserted into the insertion hole 4 of the mounting mating member Z, a contact portion inside the insertion hole 4 Sensing cylinder 59 that retreats against the resilient member 58 when it contacts 64, shutter body 60, and switching means for converting the reciprocating motion of the sensing cylinder 59 in the axial direction into the opening / closing operation of the shutter body 60 61, and is configured so that the shutter main body 60 is kept closed in the non-inserted state in the insertion hole 4, so that dust prevention in the non-inserted state is sufficiently performed, and In the state (connection complete state), the laser light is automatically allowed to pass. Therefore, it can be said that it is suitable for remote operation.

また、パージエア噴出部66を先端に有し、パージエアによって上記シャッタ本体60の防塵を行うようにしたので、一層確実に非挿入状態下での防塵が可能である。
また、先端窓ホルダ45を有し、該ホルダ45には先端窓ガラス44が内有され、さらに、上記石英チップ30の上記大径出射端面30Bに近接して内部保護用内窓ガラス51が設けられ、上記ホルダ45の着脱にかかわらずに上記大径出射端面30Bに近接して上記内窓ガラス51が固定されているので、大径出射端面30Bには常時防塵が十分に行われ、組立作業時等にも塵や汚れが付着しない。
また、上記先端窓ガラス44と石英チップ30と上記内窓ガラス51には、使用するレーザ波長に対応した無反射コーティングが施されているので、レーザの透過効率が向上し、発熱も防止できる。
また、パージエアが上記内窓ガラス51と上記先端窓ガラス44の間の空室部55に一旦導入され、このパージエアは上記先端窓ガラス44の先端側外面44Aの防塵を行うようにパージエア噴出部Mから噴出するよう構成したので、先端窓ガラス44の外面44Aが、外部の塵や汚れが付着せず、しかも、空室部55は陽圧に保持されて、内部の内窓ガラス51への塵や汚れの付着をも有効防止できる。従って、ハイパワーレーザ光の伝送に好適なものとなる。
Further, since the purge air ejection part 66 is provided at the tip and the shutter main body 60 is dust-proofed by the purge air, it is possible to more reliably prevent dust in the non-inserted state.
In addition, a tip window holder 45 is provided, and a tip window glass 44 is included in the holder 45, and an inner window glass 51 for internal protection is provided in the vicinity of the large-diameter emitting end face 30B of the quartz chip 30. Since the inner window glass 51 is fixed in close proximity to the large-diameter exit end face 30B regardless of whether the holder 45 is attached or detached, the large-diameter exit end face 30B is always sufficiently dust-proof and assembled. Dust and dirt do not adhere at times.
Further, since the tip window glass 44, the quartz chip 30 and the inner window glass 51 are provided with a non-reflective coating corresponding to the laser wavelength to be used, the laser transmission efficiency is improved and heat generation can be prevented.
Further, purge air is once introduced into the empty space 55 between the inner window glass 51 and the front window glass 44, and the purge air is ejected to the outer surface 44A of the front window glass 44 so as to prevent dust. The outer surface 44A of the front window glass 44 is not attached with external dust or dirt, and the vacant portion 55 is held at a positive pressure, so that the dust on the inner inner window glass 51 is removed. And effectively prevent the adhesion of dirt. Therefore, it is suitable for transmission of high power laser light.

また、取付用相手部材Zの挿入孔4に挿入自在な先端部を有し、かつ、該挿入孔4への挿入深さを調整するための円環状調整リング10をコネクタ軸心L1 方向に進退自在に備え、さらに、内部のレーザ伝送用光ファイバ28の出射端側焦点位置Nが、上記円環状調整リング10の上記相手部材Zへの当接面10Aの軸心方向位置に、略一致させた構成としたので、コネクタ1の外部から、焦点位置Nを確認することが可能となり、光学部品としての接続作業に好都合であり、接続される光学ヘッド部材2等の設計も容易となる。 Further, an annular adjustment ring 10 having a distal end portion that can be inserted into the insertion hole 4 of the mating member Z for mounting and adjusting the insertion depth into the insertion hole 4 is provided in the direction of the connector axis L 1 . Further, the focal position N of the emission end side of the internal laser transmission optical fiber 28 is substantially coincident with the axial direction position of the contact surface 10A of the annular adjustment ring 10 to the counterpart member Z. With this configuration, the focal position N can be confirmed from the outside of the connector 1, which is convenient for connection work as an optical component, and the design of the connected optical head member 2 and the like is easy.

また、基端側からコネクタ軸心L1 に沿って挿入されたレーザ伝送用光ファイバ28の端面28Aに、先端側に拡径する石英チップ30の細径端面30Aを融着一体化し、該石英チップ30の大径出射端面30Bにおけるエネルギ密度を低下させると共に、上記光ファイバ28の上記端面28Aを出射端側焦点位置Nに略一致させ、さらに、上記石英チップ30の大径出射端面30Bに近接して内部保護用内窓ガラス51を設け、かつ、先端寄りに先端窓ガラス44を配設し、該先端窓ガラス44の内面と上記焦点位置Nまでの軸心方向距離L44が、上記内窓ガラス51の内面と上記焦点位置Nまでの軸心方向距離L51の 1.5倍〜10倍に設定した構成であるので、先端窓ガラス44の外面におけるエネルギ密度が十分に低下できる。これに伴って、外部の塵や汚れが付着し易い先端窓ガラス44の焼損を一層確実に防止して、ハイパワーレーザ光伝送用として極めて望ましいといえる。 Further, the end surface 28A of the laser transmission optical fiber 28 inserted along the base end side to a connector axis L 1, the small-diameter end surface 30A of the quartz chip 30 whose diameter increases distally fused integrated quartz The energy density at the large-diameter exit end face 30B of the chip 30 is reduced, the end face 28A of the optical fiber 28 is made substantially coincident with the focal position N of the exit end side, and further close to the large-diameter exit end face 30B of the quartz chip 30. The inner window glass 51 for internal protection is provided, and the front window glass 44 is disposed closer to the tip, and the axial distance L 44 between the inner surface of the front window glass 44 and the focal position N is equal to the inner window glass 44. Since the configuration is set to 1.5 to 10 times the axial distance L 51 between the inner surface of the window glass 51 and the focal position N, the energy density on the outer surface of the front window glass 44 can be sufficiently reduced. Along with this, it can be said that it is extremely desirable for high power laser light transmission by more reliably preventing burning of the front window glass 44 to which external dust and dirt easily adhere.

また、レーザ伝送用光ファイバ28の先端に取付されたコネクタ1の先端部を取付用相手部材Zの挿入孔4に挿入して保持固定するコネクタ取付構造に於て、遠隔操作用ロボットRのハンド部23にて掴持された上記コネクタ1を、コネクタ軸心L1 が上記挿入孔4の孔軸心L4 に一致するように該孔軸心L4 と直交する横方向Eから送り込んで該コネクタ1を受け取って保持する遠隔操作可能なクランプ手段Cと、該クランプ手段Cにて保持された上記コネクタ1を上記孔軸心L4 に沿って移動させて上記挿入孔4に挿入させる遠隔操作可能な直線往復動手段Kとを、具備している構成であるので、遠隔操作ロボットRによって、コネクタ1を確実に、かつ、容易に相手部材Zの挿入孔4に挿入できて、作業能率が改善でき、放射線環境下等にも適用可能となる。
また、上記クランプ手段Cは、上記横方向Eから送り込まれるコネクタ1を、弾発的に拡開変形して受け取る仮保持用弾発挾持体69、及び、遠隔操作可能な半円弧体20とボルト・ナット結合21Aを有する掴持具72とを、備えているので、ロボットRのハンド部23から、一旦、コネクタ1を仮保持用弾発挾持体69へ仮渡しし、引続いて、掴持具72にて本来の掴持を行い得る。従って、単数のハンド部23をもって、順次作業が可能となる。
Further, in the connector mounting structure in which the distal end portion of the connector 1 attached to the distal end of the laser transmission optical fiber 28 is inserted into the insertion hole 4 of the mounting mating member Z and held and fixed, the hand of the remote operation robot R gripping been the connector 1 in section 23, the connector axis L 1 is by feeding the transverse direction E perpendicular to the hole axis L 4 so as to match the hole axis L 4 of the insertion hole 4 the and remotely operable clamping means C for retaining receive a connector 1, the connector 1 held by said clamping means C is moved along the hole axis L 4 remote control to insert into the insertion hole 4 Since it has a configuration including the possible linear reciprocating means K, the remote operation robot R can reliably and easily insert the connector 1 into the insertion hole 4 of the mating member Z, and the work efficiency is high. Can be improved and suitable for radiation environments It can become.
Further, the clamping means C includes a temporary holding bullet holder 69 for receiving the connector 1 fed from the lateral direction E after being elastically expanded and deformed, and a semi-circular arc body 20 and a bolt which can be remotely operated. -Since the gripping tool 72 having the nut coupling 21A is provided, the connector 1 is temporarily transferred from the hand portion 23 of the robot R to the temporary holding bullet holder 69 and subsequently gripped. The original gripping can be performed with the tool 72. Therefore, it is possible to sequentially work with a single hand unit 23.
