Description

本発明は内視鏡をプロセッサ装置等に接続するための内視鏡用コネクタ、特に防水キャップを用いて電気接点部材の腐食等を防止するための構成に関する。   The present invention relates to an endoscope connector for connecting an endoscope to a processor device or the like, and more particularly to a configuration for preventing corrosion or the like of an electrical contact member using a waterproof cap.

図10には、従来の内視鏡用コネクタ(電気コネクタ)の構成が示されており、この図10は、コネクタ1に防水キャップ2が取り付けられた状態を示している。このコネクタ1は、本体3の外周に回転(操作)リング4を所定の角度だけ回転できるように取り付けた構成とされ、本体3の接続口3aの内部に、複数のピン(電気接点部材)5が配置される。一方、防水キャップ2は、内側円筒部6と外側円筒部7からなり、内側円筒部6の外周の溝6eに、上記接続口3aの内周に密着するOリング8が取り付けられている。   FIG. 10 shows a configuration of a conventional endoscope connector (electrical connector). FIG. 10 shows a state in which a waterproof cap 2 is attached to the connector 1. The connector 1 has a structure in which a rotation (operation) ring 4 is attached to the outer periphery of the main body 3 so as to be rotated by a predetermined angle, and a plurality of pins (electrical contact members) 5 are provided inside the connection port 3a of the main body 3. Is placed. On the other hand, the waterproof cap 2 includes an inner cylindrical portion 6 and an outer cylindrical portion 7, and an O-ring 8 that is in close contact with the inner periphery of the connection port 3 a is attached to an outer groove 6 e of the inner cylindrical portion 6.

また、この種の内視鏡用コネクタでは、プロセッサ装置側のコネクタ受けに対する接続固定の方法として例えばバヨネット式が採用されており、上記防水キャップ2との接続固定についても、このバヨネット構造を利用して接続が行われる。例えば、上記外側円筒部7の先端外周の2,3箇所に、係合爪9が設けられ、この係合爪9を上記回転リング4の内周に形成されたカム溝に係合・配置する構成とされる。これによれば、係合爪9を回転リング4のカム溝に係合させ、防水キャップ2を所定の角度だけ回転させて押し込むことで、防水キャップ2をコネクタ1に接続固定することができる。   In addition, in this type of endoscope connector, for example, a bayonet type is adopted as a method of fixing the connection to the connector receiver on the processor device side, and this bayonet structure is also used for connection and fixing to the waterproof cap 2. Connection is made. For example, engaging claws 9 are provided at two or three locations on the outer periphery of the outer cylindrical portion 7, and the engaging claws 9 are engaged and arranged in cam grooves formed on the inner periphery of the rotating ring 4. It is supposed to be configured. According to this, the waterproof cap 2 can be connected and fixed to the connector 1 by engaging the engaging claw 9 with the cam groove of the rotating ring 4 and rotating the waterproof cap 2 by a predetermined angle.

図11には、上記コネクタ1とプロセッサ装置10側のコネクタ受け部の構成が示されており、このプロセッサ装置10のコネクタ受け(レセプタクル)11には、上記防水キャップ2側の係合爪9と同様の係合爪12が設けられている。従って、従来のコネクタ1では、例えば回転リング4の外周に設けられたマーク(指標)Mをプロセッサ装置10側のマークMに位置合わせしながら、該回転リング4内に上記コネクタ受け11を挿入し、カム溝を係合爪12に係合させた後、回転リング4をマークMの位置まで回転させれば、コネクタ本体3(その接続口3a)が前側へ移動しコネクタ受け11へ接続固定される。なお、このコネクタ1をコネクタ受け11から外したとき、回転リング4はバネの付勢力で元の基準位置へ戻るようになっている。 FIG. 11 shows a configuration of the connector 1 and a connector receiving portion on the processor device 10 side. The connector receiver (receptacle) 11 of the processor device 10 has an engaging claw 9 on the waterproof cap 2 side and Similar engaging claws 12 are provided. Therefore, in the conventional connector 1, for example, while the mark provided on the outer periphery of the rotating ring 4 (index) M 1 aligned with the mark M 2 of the processor unit 10 side, the connector receiving 11 to the rotating ring 4 After inserting and engaging the cam groove with the engaging claw 12, if the rotating ring 4 is rotated to the position of the mark M 3 , the connector main body 3 (its connection port 3 a) moves to the front side to the connector receiver 11. Connection is fixed. When the connector 1 is removed from the connector receiver 11, the rotating ring 4 returns to the original reference position by the biasing force of the spring.

このような内視鏡用コネクタによれば、コネクタ受け11から外したコネクタ1に、防水キャップ2を取り付けると、この防水キャップ2のOリング8が接続口3aの内周面に密着することにより、電気接点であるピン5を有するコネクタ1の内部が水密状態に維持され、防水が可能となる。そして、コネクタ1の防水を図った状態として、内視鏡(スコープ)は、洗浄が施されると共にオートクレーブ等による滅菌処理が行われる。

According to such an endoscope connector, when the waterproof cap 2 is attached to the connector 1 removed from the connector receiver 11, the O-ring 8 of the waterproof cap 2 comes into close contact with the inner peripheral surface of the connection port 3a. The inside of the connector 1 having the pins 5 that are electrical contacts is maintained in a watertight state and can be waterproofed. The endoscope (scope) is cleaned and sterilized by an autoclave or the like while the connector 1 is waterproofed.
JP-A-6-133919 JP 2000-340290 A JP 2005-278944 A JP 2001-204681 A

ところで、図10で説明した従来の内視鏡用コネクタでは、キャップ2のOリング8を接続口3aの内周面に密着させて防水を図っているが、接続口3aの外周側に、回転リング4を設けているため、この回転リング4と本体3の間の隙間に水分が浸入して付着すると、防水キャップ2をコネクタ1から外したとき、隙間に付着した(又は溜まった)水分が、ピン5を有する接続口3aの内部に垂れて入り込む場合がある。そして、この水分が浸入したコネクタ1をコネクタ受け11に接続すれば、このコネクタ受け11の内部も水分で濡れることになり、これによって、コネクタ1内のピン5だけでなく、コネクタ受け11内の電気接点も腐食する可能性がある。   In the conventional endoscope connector described with reference to FIG. 10, the O-ring 8 of the cap 2 is in close contact with the inner peripheral surface of the connection port 3a for waterproofing. Since the ring 4 is provided, when moisture enters and adheres to the gap between the rotating ring 4 and the main body 3, when the waterproof cap 2 is removed from the connector 1, the moisture attached (or accumulated) to the gap is removed. In some cases, the pin 5 hangs down and enters the connection port 3a. Then, if the connector 1 into which the moisture has entered is connected to the connector receiver 11, the inside of the connector receiver 11 will also be wetted with the moisture, whereby not only the pins 5 in the connector 1 but also the connector receiver 11 Electrical contacts can also corrode.

また、上記回転リング4が配置されず、接続口3aの外周側の該回転リング4の位置に回転しない単なる外装体が設けられる場合もあり、この場合でも、外装体と本体3との間に隙間があれば、この隙間に水分が付着し、上記と同様の不都合が生じる。   In addition, there is a case where the rotary ring 4 is not disposed and a simple exterior body that does not rotate is provided at the position of the rotary ring 4 on the outer peripheral side of the connection port 3a. If there is a gap, moisture adheres to the gap and the same disadvantages as described above occur.

従来において、コネクタ内に浸入した水分を除去するものとして、上記の特許文献1及び2があり、この特許文献1には、内視鏡装置のプラグ内にスポンジを配置し、プラグをソケットに嵌合する際に、プラグに付着した水分を上記スポンジで吸収し、プラグ内の電気接点が水に濡れることを防止する構成が開示されている。また、引用文献2には、コネクタに、電気接点部材が液密的に密着して挿通する孔を備えた水分除去カバーを設け、この水分除去カバーを移動させて電気接点部材付近に付着した水分を除去する構成が示されている。   Conventionally, there are Patent Documents 1 and 2 described above for removing moisture that has entered the connector. In Patent Document 1, a sponge is disposed in a plug of an endoscope apparatus, and the plug is fitted into a socket. A structure is disclosed in which when adhering, moisture adhering to the plug is absorbed by the sponge to prevent the electrical contacts in the plug from getting wet. Further, in the cited document 2, the connector is provided with a moisture removal cover provided with a hole through which the electrical contact member comes into close contact with the liquid, and the moisture attached to the vicinity of the electrical contact member by moving the moisture removal cover. A configuration is shown for removing.

しかしながら、上記特許文献1の場合は、スポンジの水の吸収量が許容量を超えると、水の浸入が起こり、電気接点が腐食する可能性があり、上記特許文献2の場合は、使用者が水分除去カバーの操作をする必要があるため、この除去操作を忘れたときには水分を完全に除去できないことになり、電気接点部材の腐食の可能性が残ってしまう。   However, in the case of the above-mentioned Patent Document 1, if the amount of water absorbed by the sponge exceeds the allowable amount, water may enter and the electrical contacts may be corroded. Since it is necessary to operate the moisture removal cover, if the removal operation is forgotten, the moisture cannot be completely removed, and the possibility of corrosion of the electrical contact member remains.

更に、コネクタのシールを図るものとして特許文献3があり、この特許文献3は、中継ケーブルの両端側に配置されたコネクタ同士をシール性を図りながら連結することで、コネクタ内の電気接点部をシールするものである。しかし、この特許文献3でも、上述した従来例と同様に、コネクタ同士の連結を解除するとき、その連結部分に付着した水分が各コネクタの内部に落下し、電気接点部を腐食させる可能性がある。   Furthermore, there is Patent Document 3 as a connector for sealing a connector. This Patent Document 3 connects the connectors arranged at both ends of the relay cable with sealing performance, thereby connecting the electrical contact portion in the connector. It is to be sealed. However, even in this Patent Document 3, as in the conventional example described above, when the connection between the connectors is released, there is a possibility that moisture attached to the connection part falls into each connector and corrodes the electrical contact part. is there.

また、上記特許文献4に示されるように、電気コネクタの接続筒の基部と防水キャップの外側のキャップ部材との間を第1シール部材でシールし、かつ接続筒の開口部と内側のキャップ部材との間を第2シール部材でシールするように構成し、電気コネクタの接続筒の内側と外側の両方でシール効果を高めるものも存在する。しかし、このような構成は、防水キャップが大型化すると共に、防水キャップを装着したときの電気コネクタの外周が大きくなってしまう。   In addition, as shown in Patent Document 4, a gap between the base of the connecting cylinder of the electrical connector and the outer cap member of the waterproof cap is sealed with a first seal member, and the opening of the connecting cylinder and the inner cap member There is also a structure in which the gap between the two is sealed with a second seal member, and the sealing effect is enhanced both inside and outside the connecting tube of the electrical connector. However, such a configuration increases the size of the waterproof cap and increases the outer periphery of the electrical connector when the waterproof cap is attached.

本発明は上記問題点に鑑みてなされたものであり、その目的は、接続口を有する本体とその外側に配置される回転リングや外装体等との間に付着した水分が防水キャップの取外し時等にコネクタ内に浸入することがなく、電気接点部材の腐食を確実に防止することができ、また防水キャップを装着したときでもコネクタの外周が大きくなることのない内視鏡用コネクタを提供することにある。   The present invention has been made in view of the above problems, and its purpose is to remove moisture adhered between a main body having a connection port and a rotating ring or an exterior body disposed outside the main body when the waterproof cap is removed. An endoscope connector that can reliably prevent corrosion of an electrical contact member without entering the connector or the like and that does not increase the outer periphery of the connector even when a waterproof cap is attached. There is.

上記目的を達成するために、請求項1に係る発明は、電気接点部材が内部に配置されたコネクタの接続口と、この接続口の外側に配置された外側部材とを有し、防水キャップが取り付けられる内視鏡用コネクタにおいて、上記防水キャップに、上記接続口の内周面に密着して防水をする第1シール部材を設けると共に、上記外側部材の外周を超えない大きさのシール体からなり、上記外側部材に密着して防水をする第2シール部材を設けたことを特徴とする。
請求項2に係る発明は、上記外側部材として、上記接続口外側に回転可能に配置され、上記コネクタをコネクタ受けに固定するために回転操作される回転リングを備え、この回転リングの後端側とコネクタ本体との間に、水密状態を維持する第3シール部材を設けると共に、上記防水キャップの第2シール部材を上記回転リング(の前面又は内周面)に密着配置することを特徴とする。
In order to achieve the above object, the invention according to claim 1 includes a connector connection port having an electrical contact member disposed therein, and an outer member disposed outside the connection port. In the endoscope connector to be attached, the waterproof cap is provided with a first seal member that is in close contact with the inner peripheral surface of the connection port and waterproofed, and the seal body having a size that does not exceed the outer periphery of the outer member. Thus, a second seal member that is in close contact with the outer member and waterproofs is provided.
According to a second aspect of the present invention, the outer member includes a rotating ring that is rotatably disposed outside the connection port and is rotated to fix the connector to the connector receiver. A third seal member that maintains a watertight state is provided between the connector and the connector body, and the second seal member of the waterproof cap is disposed in close contact with the rotating ring (the front surface or the inner peripheral surface thereof). .

本発明の構成によれば、コネクタの接続口内周面に密着する第1シール部材により接続口内への水分の浸入が防止されると共に、接続口外側部材(例えば外装体)に密着する第2シール部材により、該外側部材とコネクタ本体との間の隙間等に水分を付着(又は貯留)させることがなく、接続口内の電気接点部材が水分で濡れることが防止される。   According to the configuration of the present invention, the first seal member that is in close contact with the inner peripheral surface of the connection port of the connector prevents moisture from entering the connection port, and the second seal that is in close contact with the connection port outer member (for example, the exterior body). The member prevents moisture from adhering (or storing) to the gap between the outer member and the connector body, and prevents the electrical contact member in the connection port from getting wet.

請求項2の構成によれば、回転リングの前面等に密着する第2シール部材により、該回転リングとコネクタ本体との間に前側から水分が浸入することが防止され、また回転リングの後端側とコネクタ本体との間に配置された第3シール部材により、これらの間に後側から水分が浸入することが防止され、回転リングとコネクタ本体との間に水分が付着(又は貯留)しないようになる。   According to the configuration of claim 2, the second seal member that is in close contact with the front surface or the like of the rotating ring prevents moisture from entering from the front side between the rotating ring and the connector body, and the rear end of the rotating ring. The third seal member disposed between the side and the connector body prevents moisture from entering between them from the rear side, and moisture does not adhere (or accumulate) between the rotating ring and the connector body. It becomes like this.

本発明の内視鏡用コネクタによれば、接続口を有する本体とその外側に配置される回転リングや外装体等との間に付着した水分が防水キャップの取外し時等にコネクタ内に浸入することがなく、電気接点部材の腐食を確実に防止することができる。また、防水キャップを装着したときでも、コネクタの外周が大きくならず、内視鏡の洗浄、消毒、オートクレーブ等での滅菌においても取扱い易くなり、防水キャップ自体、そして防水キャップを装着したコネクタが細身となりスマートになるという効果がある。   According to the endoscope connector of the present invention, moisture adhering between the main body having the connection port and the rotating ring or the exterior body arranged outside thereof enters the connector when the waterproof cap is removed. Therefore, corrosion of the electrical contact member can be reliably prevented. In addition, even when a waterproof cap is attached, the outer circumference of the connector does not increase, making it easier to handle in endoscope cleaning, disinfection, sterilization with an autoclave, etc., and the waterproof cap itself and the connector with the waterproof cap attached are thin. It has the effect of becoming smart.

図1乃至図6には、第1実施例に係る内視鏡用コネクタの構成が示されており、この第1実施例は、図1及び図2に示されるように、コネクタ15に防水キャップ16が取り付けられる構成とされる。この防水キャップ16は、コネクタ15のケーブル側に紐状体17で連結され、この紐状体17のコネクタ側根元には、例えばリング状(その他、鉤状のものでもよい)の係止部材18が設けられており、この係止部材18により、コネクタ15を他の部材、例えば光コネクタ部等に係止できるようになっている。即ち、電気コネクタとしてのコネクタ15は、内視鏡側に設けられ、プロセッサ装置等の信号処理回路部に接続されるもので、例えば光源部に接続される内視鏡の光源コネクタから分岐されたケーブルの端部に設けられており(例えば特開2005−261837号公報)、不使用時の保管がし難いという事情がある。そのため、第1実施例では、上記係止部材18を用いて、コネクタ15を光コネクタ等の部材に係止し、保管が行い易いようになっている。   FIGS. 1 to 6 show the configuration of an endoscope connector according to the first embodiment. In the first embodiment, as shown in FIGS. 1 and 2, the connector 15 has a waterproof cap. 16 is attached. The waterproof cap 16 is connected to the cable side of the connector 15 by a string-like body 17, and a ring-like (or other hook-like) locking member 18 is provided at the connector-side base of the string-like body 17. The connector 15 can be locked to another member, such as an optical connector portion, by the locking member 18. That is, the connector 15 as an electrical connector is provided on the endoscope side and is connected to a signal processing circuit unit such as a processor device. For example, the connector 15 is branched from the light source connector of the endoscope connected to the light source unit. It is provided at the end of the cable (for example, Japanese Patent Application Laid-Open No. 2005-261837), and it is difficult to store it when not in use. Therefore, in the first embodiment, the connector 15 is locked to a member such as an optical connector by using the locking member 18 so that it can be easily stored.

また、コネクタ15は、プロセッサ装置側のコネクタ受け及び上記防水キャップ16に対する接続固定の方法として例えばバヨネット式(前進固定機構)を採用しており、このバヨネット式の接続のために、本体20の外周に回転(操作)リング21が回転可能に配置されると共に、この回転リング21には、基準位置(取付け前の位置)に戻るように本体20側からバネ付勢力が与えられている。この回転リングの21の内周面には、図11で説明したように、プロセッサ装置10のコネクタ受け(レセプタクル)11に設けられた2,3個の係合爪12に係合し、コネクタ15を少し前進させる2,3個のカム溝(斜め方向の溝)22が形成される。   The connector 15 employs, for example, a bayonet type (advance fixing mechanism) as a connection fixing method for the connector receiver on the processor device side and the waterproof cap 16, and the outer periphery of the main body 20 is used for this bayonet type connection. A rotating (operation) ring 21 is rotatably arranged, and a spring biasing force is applied to the rotating ring 21 from the main body 20 side so as to return to a reference position (position before mounting). As described with reference to FIG. 11, the inner surface of the rotating ring 21 is engaged with two or three engaging claws 12 provided on the connector receiver (receptacle) 11 of the processor device 10, and the connector 15. 2 or 3 cam grooves (grooves in an oblique direction) 22 are formed.

このような回転リング21によれば、図11のコネクタ受け11の係合爪12にカム溝22Cを係合させ、バネ付勢力に抗してマークMの位置からMの位置へ所定の角度を回転させることで、コネクタ15をコネクタ受け11に接続することができる。そして、この回転リング21を反対方向へ回転させれば、コネクタ15をコネクタ受け11から取り外すことができる。このとき、この回転リング21は、バネ付勢力によってそのマークMの位置が常に基準位置に保持されるようになっており、コネクタ15の接続及び位置合わせが容易となるように工夫されている。 With such a rotary ring 21, in Figure 11 the engaging claw 12 of the connector receiving 11 engaged with the cam groove 22C, the position of the mark M 2 against the spring bias of a predetermined the position of M 3 The connector 15 can be connected to the connector receiver 11 by rotating the angle. The connector 15 can be removed from the connector receiver 11 by rotating the rotating ring 21 in the opposite direction. At this time, the rotary ring 21 is adapted to be held always reference position is the position of the mark M 1 by the spring bias, connection and positioning of the connector 15 is devised so as to facilitate .

上記コネクタ15の本体20の前側には、接続口20aが存在し、この接続口20aの内部に、複数のコネクタ用ピン(電気接点部材)23が配置される。なお、この本体20は、ピン23を配置する前側部材20(F)と上記紐状体17の根元を取り付けた後側部材20(R)とに分かれており、これらの部材は、Oリング24で水密状態が維持されている。   A connection port 20a exists on the front side of the main body 20 of the connector 15, and a plurality of connector pins (electrical contact members) 23 are arranged inside the connection port 20a. The main body 20 is divided into a front member 20 (F) on which the pin 23 is disposed and a rear member 20 (R) to which the base of the string-like body 17 is attached. The watertight state is maintained.

一方、上記防水キャップ16は、内側円筒部26とA外側円筒部27及びB外側円筒部28からなり、これら全ての部材は、金属を使用しないようにして、合成樹脂材料(プラスチック)で形成されている。そして、上記内側円筒部26の外周、即ちコネクタ接続口20aの内側に挿入される部分の外周に形成された溝26eに、上記接続口20aの内周に密着する第1シール部材としてのOリング29が取り付けられる。   On the other hand, the waterproof cap 16 includes an inner cylindrical portion 26, an A outer cylindrical portion 27, and a B outer cylindrical portion 28. All these members are made of a synthetic resin material (plastic) without using metal. ing. Then, an O-ring as a first seal member that is in close contact with the inner periphery of the connection port 20a in the outer periphery of the inner cylindrical portion 26, that is, the groove 26e formed in the outer periphery of the portion inserted inside the connector connection port 20a. 29 is attached.

上述のように、実施例では、バヨネット式の固定機構が採用されており、上記A外側円筒部27の先端(接続側)外周の数箇所(例えば3箇所)に、係合爪30が設けられ、この係合爪30を上記回転リング21内側の円筒部材22のカム溝22Cに係合する構成となる。即ち、上記円筒部材22は、回転リング21と一体となるように組み付けられており、この円筒部材22の内周に、図3に示されるようなカム溝22Cが形成される。これによれば、回転リング21の円筒部材22のカム溝22Cのそれぞれに係合爪30を係合させ、防水キャップ16を所定の角度だけ回転させて押し込むことで、防水キャップ16の全体を前進させながらコネクタ15に接続固定することができる。   As described above, in the embodiment, a bayonet-type fixing mechanism is employed, and the engaging claws 30 are provided at several locations (for example, three locations) on the outer periphery of the tip end (connection side) of the A outer cylindrical portion 27. The engaging claw 30 is configured to engage with the cam groove 22C of the cylindrical member 22 inside the rotating ring 21. That is, the cylindrical member 22 is assembled so as to be integrated with the rotating ring 21, and a cam groove 22 </ b> C as shown in FIG. 3 is formed on the inner periphery of the cylindrical member 22. According to this, the engaging claw 30 is engaged with each of the cam grooves 22 </ b> C of the cylindrical member 22 of the rotating ring 21, and the waterproof cap 16 is rotated by a predetermined angle to be pushed in, whereby the entire waterproof cap 16 is advanced. It can be connected and fixed to the connector 15.

なお、上記バヨネット式の固定機構において、上記カム溝22Cと係合爪30の配置を逆にし、上記カム溝22Cを防水キャップ16側に、上記係合爪30をコネクタ15側に配置してもよい。また、前進固定機構として、ネジ螺合式の固定機構を採用することもでき、例えば防水キャップ16のA外側円筒部27の外周に雄ネジ部、コネクタ16の円筒部材22の内側に雌ネジ部を設けるようにしてもよい。   In the bayonet-type fixing mechanism, the cam groove 22C and the engaging claw 30 may be disposed in the reverse direction so that the cam groove 22C is disposed on the waterproof cap 16 side and the engaging claw 30 is disposed on the connector 15 side. Good. Further, as the forward fixing mechanism, a screw screw type fixing mechanism can also be adopted. For example, a male screw part is provided on the outer periphery of the A outer cylindrical part 27 of the waterproof cap 16 and a female screw part is provided on the inner side of the cylindrical member 22 of the connector 16. You may make it provide.

第1実施例では、この防水キャップ16に、上記回転リング21の前面に密着する末広がり形状の第2シール部材32が取り付けられる。この第2シール部材32は、弾性ゴム部材から形成され、図4に示されるように、円筒状基部32aとこの基部32aから先端側がラッパ状(又は傘状)に広がる末広部32bとを有し、この末広部32bは、先端側程、厚みが小さくなるように形成されており、この末広部32bの先端(の径)が広がりながら(接触面積を拡げながら)回転リング21の前面に押圧されて密着することになる。   In the first embodiment, the second seal member 32 having a divergent shape that is in close contact with the front surface of the rotating ring 21 is attached to the waterproof cap 16. The second seal member 32 is formed of an elastic rubber member, and as shown in FIG. 4, has a cylindrical base portion 32a and a divergent portion 32b whose tip side extends from the base portion 32a in a trumpet shape (or an umbrella shape). The divergent portion 32b is formed so that its thickness decreases toward the tip end side, and the tip (diameter) of the divergent portion 32b expands (expands the contact area) and is pressed against the front surface of the rotating ring 21. Will be in close contact.

また、この第2シール部材32は、図4(B)に示されるように、その末広部32bの外周の径を回転リング21、即ちコネクタ15の外径を超えない大きさに設定している。即ち、末広部32bの先端が回転リング21の前面に密着してシール効果が得られる状態で、第2シール部材32の最大外径が回転リング21(又はコネクタ15)の外径以下となるように設定される。このようにして、第1実施例では、防水キャップ16を取り付けた場合でも、シール部によってコネクタ15の外周が大きくならないようにしている。   Further, as shown in FIG. 4B, the outer diameter of the divergent portion 32b of the second seal member 32 is set to a size that does not exceed the outer diameter of the rotary ring 21, that is, the connector 15. . That is, the maximum outer diameter of the second seal member 32 is less than or equal to the outer diameter of the rotating ring 21 (or the connector 15) in a state where the tip of the divergent portion 32b is in close contact with the front surface of the rotating ring 21 and a sealing effect is obtained. Set to In this way, in the first embodiment, even when the waterproof cap 16 is attached, the outer periphery of the connector 15 is not increased by the seal portion.

図5(A),(B)には、防水キャップ16の取付け・組立ての前後の状態が示されており、第1実施例の防水キャップ16は、圧入のみで製作できるようになっている。即ち、内側円筒部26の後側(図の左側)には、複数の段差部が形成され、A外側円筒部27の後側にも、内周と外周に段差部が形成され、B外側円筒部28の内側には、後側へ行く程、内径が小さくなるように第1内周部28a、第2内周部28b、第3内周部28cが形成されており、上記内側円筒部26の外周段差部の前面26aとA外側円筒部27の内周段差部の後面27aが当接する。   5A and 5B show a state before and after the waterproof cap 16 is attached and assembled. The waterproof cap 16 of the first embodiment can be manufactured only by press-fitting. That is, a plurality of stepped portions are formed on the rear side (the left side in the figure) of the inner cylindrical portion 26, and stepped portions are formed on the inner and outer circumferences on the rear side of the A outer cylindrical portion 27. Inside the portion 28, a first inner peripheral portion 28a, a second inner peripheral portion 28b, and a third inner peripheral portion 28c are formed so that the inner diameter becomes smaller toward the rear side, and the inner cylindrical portion 26 is formed. The front surface 26 a of the outer peripheral step portion and the rear surface 27 a of the inner peripheral step portion of the A outer cylindrical portion 27 abut.

また、A外側円筒部27の外周段差部27bの前面27cがB外側円筒部28の第2内周部28bの後壁面(径方向の面)に当接することで、第1内周部28aの内周面と上記A外側円筒部27の外周段差部27bの外周面との間に、第2シール部材32の円筒状基部32aを配置して挟み込むための空間が形成されるようになっている。更に、内側円筒部26の段差部の外周に、環状の突起34が形成されると共に、この突起34を係止するために、上記第3内周部28cの後側に該第3内周部28cよりも内径が大きい第4内周部28dが設けられており、この第4内周部28dには、Oリング35が配置される。   Further, the front surface 27c of the outer peripheral step portion 27b of the A outer cylindrical portion 27 abuts on the rear wall surface (radial surface) of the second inner peripheral portion 28b of the B outer cylindrical portion 28, so that the first inner peripheral portion 28a Between the inner peripheral surface and the outer peripheral surface of the outer peripheral stepped portion 27b of the A outer cylindrical portion 27, a space for placing and sandwiching the cylindrical base portion 32a of the second seal member 32 is formed. . Further, an annular projection 34 is formed on the outer periphery of the step portion of the inner cylindrical portion 26, and the third inner peripheral portion is disposed on the rear side of the third inner peripheral portion 28c in order to lock the projection 34. A fourth inner peripheral portion 28d having an inner diameter larger than 28c is provided, and an O-ring 35 is disposed on the fourth inner peripheral portion 28d.

従って、上記の構成によれば、図5(B)に示されるように、第4内周部28dにOリング35を取り付けながら、B外側円筒部28の第1内周部28aに第2シール部材基部32aを配置し、A外側円筒部27と内側円筒部26を順に取り付け、この内側円筒部26を押し込む(圧入する)と、突起34が第4内周部28dに係止することにより、第2シール部材32がB外側円筒部28の第1内周部28aとA外側円筒部27の外周段差部27bとの間に、挟まれるようにして取り付けられる。なお、上記A外側円筒部27の役割を内側円筒部26に持たせ、A外側円筒部27をなくすようにしてもよい。   Therefore, according to the above configuration, as shown in FIG. 5B, the second seal is attached to the first inner peripheral portion 28a of the B outer cylindrical portion 28 while the O-ring 35 is attached to the fourth inner peripheral portion 28d. When the member base portion 32a is arranged, the A outer cylindrical portion 27 and the inner cylindrical portion 26 are attached in order, and the inner cylindrical portion 26 is pushed in (press-fit), the protrusion 34 is locked to the fourth inner peripheral portion 28d, The second seal member 32 is attached so as to be sandwiched between the first inner peripheral portion 28 a of the B outer cylindrical portion 28 and the outer peripheral step portion 27 b of the A outer cylindrical portion 27. Note that the inner cylindrical portion 26 may have the role of the A outer cylindrical portion 27, and the A outer cylindrical portion 27 may be eliminated.

また、第1実施例では、図1に示されるように、回転リング21の後側(図の右側)においてもシール部材を設けている。即ち、本体20の後側部材20(R)の先端側外周面に、環状の溝20eを設け、この溝20eに第3シール部材としてのOリング37(図6)を取り付け、このOリング37を回転リング21の後側の内面に密着させる。このとき、図6に示されるように、Oリング37によるしめしろ(密着により潰される断面円の径方向の長さ)を0.05〜0.1mmの範囲に設定することで、水密状態を保ちつつ、回転リング21の回転動作に影響が出ないようにしている。   In the first embodiment, as shown in FIG. 1, a seal member is also provided on the rear side (right side in the drawing) of the rotating ring 21. That is, an annular groove 20e is provided on the outer peripheral surface on the front end side of the rear member 20 (R) of the main body 20, and an O-ring 37 (FIG. 6) as a third seal member is attached to the groove 20e. Is brought into close contact with the inner surface of the rear side of the rotating ring 21. At this time, as shown in FIG. 6, by setting the interference by the O-ring 37 (the length in the radial direction of the cross-sectional circle crushed by the close contact) in a range of 0.05 to 0.1 mm, the watertight state is set. The rotation operation of the rotating ring 21 is not affected while maintaining it.

第1実施例は以上の構成からなり、図2の状態から、防水キャップ16の係合爪30を回転リング21(円筒部材22)の内周のカム溝22Cに係合させ、防水キャップ16を所定の角度だけ回転させると、防水キャップ16が前進しながら(コネクタ15内へ引き込まれるようにして)、図1に示されるように、コネクタ15に取り付けられ、内側円筒部26の外周に配置されたOリング(第1シール部材)29によってコネクタ15の接続口20aの内部が水密状態とされる。   The first embodiment is configured as described above. From the state shown in FIG. 2, the engaging claw 30 of the waterproof cap 16 is engaged with the cam groove 22C on the inner periphery of the rotating ring 21 (cylindrical member 22). When rotated by a predetermined angle, the waterproof cap 16 moves forward (withdrawn into the connector 15), and is attached to the connector 15 and disposed on the outer periphery of the inner cylindrical portion 26 as shown in FIG. The O-ring (first seal member) 29 brings the inside of the connection port 20a of the connector 15 into a watertight state.

また同時に、防水キャップ16の前進動作に連動して、第2シール部材32の末広部32bが少し広がりながら回転リング21の前面に押圧されて密着する。即ち、上述のように、防水キャップ16の係合爪30を回転リング21のカム溝22Cに係合させているため、そのカム作用によって、回転する防水キャップ16がコネクタ15側に押し付けられる方向(図1,図2の右方向)に前進移動し、これによって、第2シール部材32と回転リング21の前面が確実に密着し、コネクタ15の前側から回転リング21と本体20との間への水分の浸入が防止される。更に、コネクタ15の後側(ケーブル側)では、本体20(R)の外周に配置された第3シール部材であるOリング37が回転リング21の内周面に密着しているので、コネクタ15の後側から回転リング21と本体20との間への水分の浸入が防止され、この結果、回転リング21と本体20との間の水密状態が確保される。   At the same time, in conjunction with the forward movement of the waterproof cap 16, the divergent portion 32b of the second seal member 32 is pressed against the front surface of the rotating ring 21 while being slightly expanded. That is, since the engaging claw 30 of the waterproof cap 16 is engaged with the cam groove 22C of the rotating ring 21 as described above, the rotating waterproof cap 16 is pressed against the connector 15 side by the cam action ( 1, the second seal member 32 and the front surface of the rotating ring 21 are securely adhered to each other, and the front side of the connector 15 is connected between the rotating ring 21 and the main body 20. Infiltration of moisture is prevented. Further, on the rear side (cable side) of the connector 15, the O-ring 37, which is a third seal member disposed on the outer periphery of the main body 20 (R), is in close contact with the inner peripheral surface of the rotating ring 21. Intrusion of moisture between the rotating ring 21 and the main body 20 from the rear side is prevented, and as a result, a watertight state between the rotating ring 21 and the main body 20 is ensured.

このようにして、第1実施例では、コネクタ接続口20aの部分をシールするだけでなく、回転リング21と本体20との間もシールすることになり、特に回転リング21と本体20との間における水分の付着又は貯留をなくすことにより、コネクタピン23及びその周辺部分の腐食が良好に防止され、その結果、コネクタ受け側の電気接点部材の腐食も防止できることになる。そして、第1実施例では、上記第3シール部材であるOリング37のしめしろが0.05〜0.1mmの範囲で設定されており、これによって回転リング21の良好な回転動作が確保されている。   In this way, in the first embodiment, not only the portion of the connector connection port 20a is sealed, but also the space between the rotating ring 21 and the main body 20 is sealed. By eliminating the adhesion or accumulation of moisture in the connector, corrosion of the connector pin 23 and its peripheral portion can be satisfactorily prevented, and as a result, corrosion of the electrical contact member on the connector receiving side can also be prevented. In the first embodiment, the interference of the O-ring 37 serving as the third seal member is set in a range of 0.05 to 0.1 mm, thereby ensuring a good rotational operation of the rotating ring 21. ing.

実施例のコネクタ15では、図11で説明したように、回転リング21の外周に設けられたマークMをプロセッサ装置側のマークMに位置合わせした状態で、該回転リング21内に上記コネクタ受け11を挿入し、カム溝22Cを係合爪12に係合させながら回転リング21を接続位置マークMの位置まで回転させれば、コネクタ本体20(その接続口20a)が前側へ移動しコネクタ受け11へ接続固定される。一方、このコネクタ15をコネクタ受け11から外したときには、回転リング21はバネの付勢力で元の基準位置へ戻る。このような構造のため、従来では、回転リング21と本体20との間に、水分が浸入することが生じていたが、実施例の防水キャップ16によれば、この回転リング21の内側への水分の浸入が防止される。また、この部分の水分の浸入によって、回転リング21を復帰させるバネ付勢力の機構に影響を与えることが防止され、バネ付勢力の低下もなくせるという利点がある。 In the connector 15 according to the embodiment, as described with reference to FIG. 11, the mark M 1 provided on the outer periphery of the rotary ring 21 is aligned with the mark M 2 on the processor device side, and the connector is placed in the rotary ring 21. receiving 11 insert the is rotated to the position of the connecting position mark M 3 the rotating ring 21 while engaging the cam groove 22C claws 12, the connector body 20 (the connecting port 20a) is moved to the front side It is connected and fixed to the connector receiver 11. On the other hand, when the connector 15 is removed from the connector receiver 11, the rotating ring 21 returns to the original reference position by the biasing force of the spring. Due to such a structure, conventionally, moisture has entered between the rotating ring 21 and the main body 20. However, according to the waterproof cap 16 of the embodiment, the inside of the rotating ring 21 is inward. Infiltration of moisture is prevented. Further, the intrusion of moisture at this portion prevents the influence of the spring biasing force mechanism for returning the rotating ring 21, and there is an advantage that the spring biasing force can be prevented from being lowered.

なお、この第1実施例では、本体20の外周に回転リング21が回転可能に設けられている場合を説明したが、この回転リング21の代わりに、単なる外装体が固定状態で設けられる場合もあり、この場合は、外装体の後側が本体後側部材20(R)に対し水密状態で固定されるので、上記第2シール部材32を外装体の前面に密着配置することで、外装体と本体20との間の隙間に水分が浸入・付着することを防止することができる。   In the first embodiment, the case where the rotating ring 21 is rotatably provided on the outer periphery of the main body 20 has been described. However, a simple exterior body may be provided in a fixed state instead of the rotating ring 21. Yes, in this case, the rear side of the exterior body is fixed in a watertight manner to the main body rear side member 20 (R), so that the second seal member 32 is disposed in close contact with the front surface of the exterior body, It is possible to prevent moisture from entering and adhering to the gap between the main body 20.

また、第1実施例では、第2シール部材32の末広部32bを先端側がラッパ状に拡張する末広がり形状にすると共に、この末広部32bの外径が回転リング21(コネクタ15)の外径を超えない大きさにしたので、防水キャップ16を取り付けた場合でも、シール部によってコネクタ15の外周が大きくならず、内視鏡(スコープ)の洗浄、消毒やオートクレーブ等による滅菌において取り扱い易くなり、既存の洗浄器等に無理なく収容できるという利点がある。しかも、防水キャップ自体、そして防水キャップを装着したコネクタが細身となり、スマートな格好となる。   Further, in the first embodiment, the divergent portion 32b of the second seal member 32 has a divergent shape in which the tip side expands in a trumpet shape, and the outer diameter of the divergent portion 32b is the outer diameter of the rotating ring 21 (connector 15). Since the size does not exceed, even when the waterproof cap 16 is attached, the outer periphery of the connector 15 is not enlarged by the seal portion, and it becomes easy to handle in the endoscope (scope) cleaning, disinfection, sterilization by autoclave, etc. There is an advantage that it can be accommodated without difficulty in a washing machine. In addition, the waterproof cap itself and the connector fitted with the waterproof cap become slender, and it looks smart.

更に、上述したように、第1実施例では、防水キャップ16に金属を使用せず、合成樹脂部材とゴム部材を用いて製作し、また第2シール部材32を配置したB外側円筒部28に対し、A外側円筒部27を介して内側円筒部26を圧入するだけで、接着剤や固定ネジを用いずに、第2シール部材32を取り付けるようにしたので、防水キャップの製作が容易になると共に、洗浄や滅菌による防水キャップの金属部分の腐食や接着剤の劣化を抑制することができるという利点がある。即ち、洗浄、消毒又はオートクレーブ等の滅菌では、内視鏡が強酸性水等に晒されると共に高温多湿の状態に置かれるため、ネジ等の金属が腐食したり、接着剤の接着効果が失われたりし、防水キャップが破損することになるが、実施例ではこのような不都合が回避される。   Further, as described above, in the first embodiment, the waterproof cap 16 is made of a synthetic resin member and a rubber member without using a metal, and the B outer cylindrical portion 28 in which the second seal member 32 is disposed is used. On the other hand, since the second seal member 32 is attached by simply press-fitting the inner cylindrical portion 26 via the A outer cylindrical portion 27 without using an adhesive or a fixing screw, the waterproof cap can be easily manufactured. In addition, there is an advantage that corrosion of the metal portion of the waterproof cap and deterioration of the adhesive due to cleaning and sterilization can be suppressed. That is, in sterilization such as cleaning, disinfection, or autoclave, the endoscope is exposed to strongly acidic water, etc. and placed in a hot and humid state, so that metals such as screws are corroded and the adhesive effect of the adhesive is lost. However, although the waterproof cap is damaged, such an inconvenience is avoided in the embodiment.

図7には、第2実施例の構成が示されており、この第2実施例は、第3シール部材としてVリングを使用したものである。即ち、回転リング21の後端内周において内側へ突出する環状凸部(又は内径が小さくなる環状段差部でもよい)40の後端と、本体後側部材20(R)の先端外周において先端側へ向けて外径が小さくなる段差部41との間に形成された空間に、Vリング42が配置され、このVリング42の先端面が環状凸部40の後端面に密着するように取り付けられる。このようなVリング42によっても、上記Oリング37と同様に、コネクタ15の後側から、回転リング21と本体20との間に水分が浸入せず、前側の第2シール部材32と相俟って、回転リング21と本体20との間を水密状態に維持することができる。   FIG. 7 shows the configuration of the second embodiment. This second embodiment uses a V-ring as the third seal member. That is, the rear end of the annular protrusion (or an annular stepped portion having a smaller inner diameter) 40 that protrudes inwardly at the inner periphery of the rear end of the rotary ring 21 and the front end side of the outer periphery of the front end of the main body rear member 20 (R). A V-ring 42 is disposed in a space formed between the stepped portion 41 whose outer diameter decreases toward the surface, and is attached so that the front end surface of the V-ring 42 is in close contact with the rear end surface of the annular convex portion 40. . Similarly to the O-ring 37, such a V-ring 42 does not allow moisture to enter between the rotary ring 21 and the main body 20 from the rear side of the connector 15, and is compatible with the second seal member 32 on the front side. Thus, the space between the rotating ring 21 and the main body 20 can be maintained in a watertight state.

図8には、第3実施例の構成が示されており、この第3実施例は、第3シール部材としてオイルシールを使用したものである。即ち、回転リング21の後端内周において先端側へ向けて内径が小さくなる環状段差部44と、後側本体20(R)の先端外周において先端側へ向けて外径が小さくなる段差部45とで形成された空間に、オイルシール46が配置され、このオイルシール46内周側片が上記段差部45の外周面に密着するように取り付けられる。このようなオイルシール46によっても、上記Oリング37、Vリング42と同様に、前側の第2シール部材32と相俟って、回転リング21と本体20との間を水密状態に維持することができる。また、上記第2及び第3実施例の場合も、Vリング42,オイルシール46のしめしろを0.05〜0.1mmの範囲に設定することにより、回転リング21の良好な回転動作が確保される。   FIG. 8 shows the configuration of the third embodiment. In the third embodiment, an oil seal is used as the third seal member. That is, an annular stepped portion 44 whose inner diameter decreases toward the front end side on the inner periphery of the rear end of the rotating ring 21, and a stepped portion 45 whose outer diameter decreases toward the front end side on the outer periphery of the rear end of the rear body 20 (R). The oil seal 46 is disposed in the space formed by the above-described components, and the oil seal 46 inner peripheral piece is attached so as to be in close contact with the outer peripheral surface of the stepped portion 45. Even with such an oil seal 46, like the O-ring 37 and the V-ring 42, in combination with the second seal member 32 on the front side, the space between the rotating ring 21 and the main body 20 is maintained in a watertight state. Can do. Also in the case of the second and third embodiments described above, by setting the interference between the V ring 42 and the oil seal 46 in the range of 0.05 to 0.1 mm, a satisfactory rotating operation of the rotating ring 21 is ensured. Is done.

図9には、第4実施例の構成が示されており、この第4実施例は、第2シール部材を回転リングの内周面に密着配置したものである。図9に示されるように、防水キャップ16の第2シール部材48は、円筒状基部48aにその径よりも大きな径の円筒状本体を一体形成してなり、この本体の先端側外周に環状の凸部48bが設けられた構成とされ、第1実施例の場合と同様に、上記基部48aを第1内周部28aに配置し、A外側円筒部27と内側円筒部26を順に取り付け、この内側円筒部26を圧入することにより、突起34が第4内周部28dに係止し、第2シール部材48がB外側円筒部28の第1内周部28aとA外側円筒部27の外周段差部27bとの間に、挟まれるようにして取り付けられる。   FIG. 9 shows the configuration of the fourth embodiment. In the fourth embodiment, the second seal member is disposed in close contact with the inner peripheral surface of the rotating ring. As shown in FIG. 9, the second seal member 48 of the waterproof cap 16 is formed by integrally forming a cylindrical main body 48a with a cylindrical main body having a diameter larger than that of the cylindrical base portion 48a. As in the case of the first embodiment, the base portion 48a is disposed on the first inner peripheral portion 28a, and the A outer cylindrical portion 27 and the inner cylindrical portion 26 are sequentially attached. By press-fitting the inner cylindrical portion 26, the protrusion 34 is locked to the fourth inner peripheral portion 28 d, and the second seal member 48 is the outer periphery of the first inner peripheral portion 28 a of the B outer cylindrical portion 28 and the outer peripheral portion 27 It is attached so as to be sandwiched between the stepped portion 27b.

そして、防水キャップ16を取り付けたときには、上記第2シール部材48の凸部48bが回転リング21の内周に密着することにより、コネクタ15の前側から、回転リング21と本体20との間に水分が浸入することが防止され、コネクタ15の後側のOリング37と相俟って、回転リング21と本体20との間が水密状態に維持される。   When the waterproof cap 16 is attached, the convex portion 48 b of the second seal member 48 comes into close contact with the inner periphery of the rotating ring 21, so that moisture is interposed between the rotating ring 21 and the main body 20 from the front side of the connector 15. Intrusion is prevented, and together with the O-ring 37 on the rear side of the connector 15, the space between the rotating ring 21 and the main body 20 is maintained in a watertight state.

このような第4実施例においても、第2シール部材48の外周が回転リング21(コネクタ15)の外径を超えない大きさとなるので、防水キャップ16を取り付けた場合でも、シール部によってコネクタ15の外周が大きくならず、内視鏡(スコープ)の洗浄、消毒やオートクレーブ等による滅菌において取り扱い易いという利点がある。   Also in the fourth embodiment, since the outer periphery of the second seal member 48 has a size that does not exceed the outer diameter of the rotating ring 21 (connector 15), even when the waterproof cap 16 is attached, the connector 15 is attached by the seal portion. There is an advantage that the outer periphery of the endoscope is not enlarged, and it is easy to handle the endoscope (scope) for cleaning, disinfection, sterilization by autoclave, and the like.

なお、この第4実施例は、回転リング21の代わりに、単に外装体が固定状態で設けられる場合にも適用でき、上記第2シール部材48の凸部48bを外装体の内周面に密着配置すれば、外装体と本体20との間の隙間への水分の浸入が防止される。   The fourth embodiment can also be applied to a case where the exterior body is simply provided in place of the rotating ring 21, and the convex portion 48b of the second seal member 48 is in close contact with the inner peripheral surface of the exterior body. If it arrange | positions, the penetration | invasion of the water | moisture content to the clearance gap between an exterior body and the main body 20 is prevented.
