It is placed inside the opening/closing pipe. The movable switching contact elements of a vacuum switch must be guided with as little play as possible, in order to prevent them from tilting relative to the other (usually stationary) switching contact element. be. Furthermore, the movable switching contact member must be permanently electrically connected to the current-carrying parts of the vacuum switch.

本発明は、特には可動式開閉接点部材の案内に関して改良された、真空開閉器を提供することを課題とする。 SUMMARY OF THE INVENTION It is an object of the present invention to provide a vacuum switch which is improved in particular with regard to the guidance of movable switching contact members.

この課題は、本発明によれば請求項１の特徴を備える真空開閉器により、解決される。 This object is solved according to the invention by a vacuum switch having the features of claim 1.

本発明の有利な実施態様は、従属請求項の対象である。 Advantageous embodiments of the invention are the subject of the dependent claims.

本発明による真空開閉器は、
- 可動式開閉接点部材を備えた真空開閉管と、
- 円筒状の内壁を備えた導電性中空体として形成されたソケット部材（５）であって、可動式開閉接点部材の真空開閉管から引き出された端部が突入しているソケット部材と、
- 可動式開閉接点部材の端部と固定的に接続されている導電性のガイド接点部材と、
- ガイド接点部材にて互いに間隔をおいて配置された少なくとも２つのガイドリング及びガイド接点部材にて配置された導電性の電流伝達部材と、を備え、
- ガイドリングと電流伝達部材が、それぞれ、ガイド接点部材の周囲に環状に延びており、ソケット部材の内壁に当接している。 The vacuum switch according to the present invention includes:
- A vacuum switching tube equipped with a movable switching contact member,
- a socket member (5) formed as a conductive hollow body with a cylindrical inner wall, into which an end pulled out from the vacuum switching tube of the movable switching contact member protrudes;
- a conductive guide contact member fixedly connected to the end of the movable switching contact member;
- at least two guide rings spaced from each other at the guide contact member and an electrically conductive current transmission member located at the guide contact member;
- a guide ring and a current transmission member each extend annularly around the guide contact member and abut against the inner wall of the socket member;

本発明による真空開閉器では、したがって、真空開閉管の可動式開閉接点部材は、導電性のガイド接点部材によって保持され、このガイド接点部材は、多数のガイドリングを介して、導電性のソケット部材の内壁にて案内される。それにより、ガイド接点部材は、ソケット部材にて可動式開閉接点部材をガイドリングを介して案内することを可能にする。ガイド接点部材との可動式開閉接点部材の固定的な接続、及び、ガイド接点部材でのガイドリングの相互に離間された配置、は、有利には、可動式開閉接点部材をほとんど遊びなくガイドすることを可能にする。さらにガイド接点部材は電流伝達部材によってソケット部材に導電的に接続されており、従ってさらに可動式開閉接点部材のソケット部材との持続的な電気的接続をも、可能にする。 In the vacuum switch according to the present invention, therefore, the movable switching contact member of the vacuum switching tube is held by the conductive guide contact member, and the guide contact member is connected to the conductive socket member via a large number of guide rings. You will be guided on the inner wall. Thereby, the guide contact member allows the socket member to guide the movable switching contact member via the guide ring. The fixed connection of the movable switching contact element with the guide contact element and the mutually spaced arrangement of the guide rings on the guide contact element advantageously guide the movable switching contact element with little play. make it possible. Furthermore, the guide contact element is electrically conductively connected to the socket element by means of a current transmission element, thus also making possible a permanent electrical connection of the movable switching contact element with the socket element.

本発明による真空開閉器の一構成では、ガイドリングはポリテトラフルオロエチレンから製造されている。ポリテトラフルオロエチレンは、摩擦係数が非常に低く、したがって良好なスライド特性を有し、また非常に耐熱性も高いので、ガイドリングに適した材料である。 In one configuration of the vacuum switch according to the invention, the guide ring is manufactured from polytetrafluoroethylene. Polytetrafluoroethylene is a suitable material for guide rings because it has a very low coefficient of friction and therefore good sliding properties and is also very heat resistant.

本発明による真空開閉器のさらなる構成では、電流伝達部材は、弾性的に支持された導電性の接触薄板から構成される構造を有する。弾性的に支持された接触薄板により、有利には、低摩擦であり、同時に、多数の電気接点により信頼性の高い、電流伝達部材とソケット部材との間の電気的接続、が可能となる。 In a further embodiment of the vacuum switch according to the invention, the current transmission element has a structure consisting of an elastically supported electrically conductive contact plate. The elastically supported contact plate advantageously allows an electrical connection between the current-carrying member and the socket member that is low-friction and at the same time reliable due to the large number of electrical contacts.

本発明による真空開閉器のさらなる構成では、ガイド接点部材は、アルミニウム、銅、アルミニウム合金、または銅合金から製造されている。これは、有利には、ガイド接点部材の高い導電性を可能にする。 In a further embodiment of the vacuum switch according to the invention, the guide contact element is manufactured from aluminum, copper, an aluminum alloy or a copper alloy. This advantageously allows a high electrical conductivity of the guide contact member.

本発明による真空開閉器のさらなる構成では、ガイド接点部材は、ほぼ円筒状の外壁であって、真空開閉管と向かい合う第１の端部領域であって第１のガイドリングが配置されている第１の端部領域及び真空開閉管とは離背する第２の端部領域であって第２のガイドリングが配置されている第２の端部領域を備える外壁を有している。これにより、これらのガイドリングをガイド接点部材にて可能な限り最大の間隔で配置すること、が可能となる。これは、有利には、ソケット部材におけるガイド接点部材の案内の遊び、従ってまた可動式開閉接点部材の案内の遊び、を最小化する。 In a further embodiment of the vacuum switch according to the invention, the guide contact member has a substantially cylindrical outer wall and a first end region facing the vacuum switch tube, in which the first guide ring is arranged. The vacuum opening/closing tube has an outer wall including a second end region remote from the first end region and the vacuum opening/closing tube, and in which a second guide ring is disposed. This makes it possible to arrange these guide rings at the maximum possible spacing in the guide contact member. This advantageously minimizes the guiding play of the guide contact member in the socket member and thus also the guiding play of the movable switching contact member.

本発明による真空開閉器のさらなる構成は、可動式開閉接点部材の端部と接続されている力伝達部材を備える。これにより、開閉接点部材及びガイド接点部材を動かすために、可動式開閉接点部材へ駆動力を伝達することができる。 A further configuration of the vacuum switch according to the invention comprises a force transmitting member which is connected to the end of the movable switching contact member. Thereby, driving force can be transmitted to the movable switching contact member in order to move the switching contact member and the guide contact member.

本発明による真空開閉器のさらなる構成では、ガイド接点部材の外壁は、可動式開閉接点部材の端部及び力伝達部材の少なくとも一部分、の周りを取り囲んで延びている。それにより、ガイド接点部材の外壁の、力伝達部材へ向かっての広がりが実現され、これはガイドリング同士の可能な限り大きな間隔が可能となり、それにより、ソケット部材でのガイド接点部材の案内の遊びが減少する。 In a further embodiment of the vacuum switch according to the invention, the outer wall of the guide contact element extends around the end of the movable switching contact element and at least a part of the force transmission element. As a result, a widening of the outer wall of the guide contact element towards the force transmission element is achieved, which allows for the largest possible spacing between the guide rings and thereby improves the guidance of the guide contact element in the socket element. Play is reduced.

本発明による真空開閉器のさらなる構成では、力伝達部材は、ねじ付きボルトによって、可動式開閉接点部材の端部と接続されている。さらに、楔状固定板が設けられていてもよく、当該楔状固定板は、可動式開閉接点部材の端部と力伝達部材との間に配置されており、また、当該楔状固定板によって、ねじ付きボルトが案内されている。これにより、力伝達部材の可動式開閉接点部材との機械的に安定した接続が可能になる。 In a further embodiment of the vacuum switch according to the invention, the force transmission element is connected to the end of the movable switching contact element by means of a threaded bolt. Furthermore, a wedge-shaped fixing plate may be provided, and the wedge-shaped fixing plate is disposed between the end of the movable switching contact member and the force transmission member, and the wedge-shaped fixing plate allows the threaded Bolt is guided. This enables a mechanically stable connection of the force transmission member to the movable switching contact member.

本発明による真空開閉器のさらなる構成では、力伝達部材は、ばねパケット用のハウジングとして形成されている。これはばねパケットを力伝達部材に配置することを可能にし、当該ばねパケットを用いて、弾性力が力伝達部材及び第２の開閉接点部材に作用され、真空開閉管内での電気接点を確実に閉じることができる。 In a further embodiment of the vacuum switch according to the invention, the force transmission element is designed as a housing for a spring packet. This makes it possible to arrange a spring packet on the force transmitting member, with which an elastic force is exerted on the force transmitting member and on the second switching contact member, ensuring electrical contact in the vacuum switching tube. Can be closed.
