【発明の詳細な説明】
本発明は、構造簡単で、かつ製造容易な高耐圧密封スイ
ッチを提供しようとするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention aims to provide a high voltage sealed switch that has a simple structure and is easy to manufacture.
従来から存在する高耐圧密封スイッチとして、例えばガ
ラス等の密封容器の両端から封入され、中央にて対向接
点部を構成した一対のリード片を具備したリードスイッ
チを例にとると、１つには前記密封容器内を高真空排気
または高圧ガス封入することにより高耐圧化を図る方法
、または複数個のリードスイッチを直列に接続して高耐
圧化を図る方法等がとられているが、前者はスイッチ製
造工程が複雑、かつコストアップになり、さらに接点ギ
ャップとしては１点であるだめ、おのずから耐圧的に限
界があり、また後者においては、スイッチを１本１本接
続しなければならず全体構成として大きく、したがって
構成しにくく、また接続工数アップなどの点から、やは
りコストアップになっていた。As an example of a conventional high-voltage sealed switch, for example, a reed switch is sealed from both ends of a sealed container made of glass or the like, and is equipped with a pair of reed pieces that form opposing contact points in the center. Methods of increasing the pressure resistance by evacuating the sealed container to a high vacuum or filling it with high-pressure gas, or connecting multiple reed switches in series have been used. The switch manufacturing process becomes complicated and costs increase, and since there is only one contact gap, there is a natural limit to the voltage resistance, and in the latter case, each switch must be connected one by one, which reduces the overall structure. It is large and therefore difficult to configure, and the cost increases due to increased connection man-hours.
本発明は、上記従来の欠点に鑑みてなされたもので、以
下本発明の一実施例を第１図〜第３図によって説明する
。The present invention has been made in view of the above-mentioned conventional drawbacks, and one embodiment of the present invention will be described below with reference to FIGS. 1 to 3.
第１図において、１〜３は各々ガラス等からなる密封容

パイプからなるリード片７，８゜９．１０を封入したス
イッチ部であり、前記スイッチ部１の片方リード片８を
次段スイッチ部２のリード片に共用し、また同時にスイ
ッチ部２の他方リード片９をさらに次段スイッチ部３の
リード片に共用している。In FIG. 1, 1 to 3 are switches in which lead pieces 7, 8, 9, and 10 are enclosed, each consisting of a pair of metal pipes that constitute a contact point at the center of a sealed container 4, 5, 6 made of glass or the like. , one lead piece 8 of the switch part 1 is commonly used as the lead piece of the next stage switch part 2, and at the same time, the other lead piece 9 of the switch part 2 is also used as the lead piece of the next stage switch part 3. There is.
ここで、リード片８，９は前段と次段スイッチ部が通気
容易なように、例えば第２図Ａのように通気部ａを有す
る形状、または第２図Ｂのように金属パイプの１部に通
気穴すをあけた形状となっている。Here, the lead pieces 8 and 9 have a shape that has a ventilation part a as shown in FIG. 2A, or a part of a metal pipe as shown in FIG. It has a shape with ventilation holes in it.
次にこの状態にて例えば真空封入する場合、リード片１
０を封止して第３図のように金属パイプからなるリード
片７部を、真空排気装置１１の接合部１２において、ゴ
ムシール１３等を、締め金具１４で締めつけて接合し、
その後所定の圧力に真空排気、加熱ベー′キング等を行
った後、リード片７のＡ点にて冷間圧接等の方法にて封
止して、直列に二接点部を具備一体構成し、高真空に密
封された高耐圧スィッチを得る。Next, when vacuum sealing is performed in this state, for example, lead piece 1
0, and as shown in FIG. 3, the 7 lead pieces made of metal pipe are joined at the joint 12 of the vacuum exhaust device 11 by tightening the rubber seal 13 etc. with the fastener 14.
After that, after performing evacuation to a predetermined pressure, heating baking, etc., the lead piece 7 is sealed at point A by a method such as cold pressure welding, and two contact parts are integrated in series. Obtain a high voltage resistant switch sealed in a high vacuum.
同様にして所要耐圧に応じてさらに多接点構成とするこ
とは容易である。In the same way, it is easy to configure a structure with more contacts depending on the required withstand voltage.
以上の説明から明らかなように本発明によれば、１本１
本のスイッチを各々接続することなく、多数の密封接点
部を一体構成した、かつ密封容器内部（密封接点部）を
高真空または高圧ガス封入した簡易、かつ低コストな高
耐圧密封スイッチを得ることができる。As is clear from the above description, according to the present invention, one
To obtain a simple, low-cost, high-voltage sealed switch that integrally configures a large number of sealed contact parts without connecting individual switches, and in which the inside of a sealed container (sealed contact parts) is filled with high vacuum or high-pressure gas. I can do it.
また単一のリードスイッチを犬型にする場合は、一対の
接点で得られる耐圧を自由に選定することがある電圧以
上になると非常に困難であるが、本発明では単に直列本
数の増加により対応できるという効果を有する。In addition, when making a single reed switch into a dog shape, it is extremely difficult to freely select the withstand voltage obtained by a pair of contacts when the voltage exceeds a certain voltage, but with the present invention, this can be solved by simply increasing the number of wires connected in series. It has the effect of being able to.
