［産業上の利用分野］
本発明は導電液体接点リレーに関し、特に高速形の導電
液体接点リレーに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a conductive liquid contact relay, and more particularly to a high speed conductive liquid contact relay.
［従来の技術］
従来の導電液体接点リレーとしては二つの固定電極に設
けられた磁石の強さを不平衡にして可動電極を固定電極
の一方に接触させておき、駆動電流により反転させる片
側安定型リレーと、磁石の強さを平衡にしておいて駆動
電流の方向を変えることにより可動電極の接触位置を反
転させる両側安定型リレーの二種類が有る。[Prior art] Conventional conductive liquid contact relays are one-sided stabilized in which the strengths of the magnets provided on two fixed electrodes are unbalanced, the movable electrode is kept in contact with one of the fixed electrodes, and the drive current is reversed. There are two types of relays: type relays and double-sided stabilized relays in which the contact position of the movable electrode is reversed by balancing the strength of the magnet and changing the direction of the drive current.
片側安定型リレーは板バネの復帰力を有する可動電極を
もつ導電液体接点スイッチを内蔵し、駆動電流を流して
反転状態を維持するようにしていた。Single-sided stabilized relays had a built-in conductive liquid contact switch with a movable electrode that had the restoring force of a leaf spring, and were designed to maintain the reversed state by applying a driving current.
また、両側安定型導電液体接点リレーでは駆動電流の極
性を変化させて反転させるようにしていた。Furthermore, in double-sided stable conductive liquid contact relays, the polarity of the drive current is changed and reversed.
尚、この場合でも板バネを用いている。Note that a leaf spring is used in this case as well.
［解決すべき問題点］
上述した従来の導電液体接点リレーのうち片側安定型導
電液体接点リレーは、板バネの復帰力を有する可動電極
を持つ導電液体接点スイッチを内蔵しているため、反転
状態を保持するには駆動電流を流し続けなくてはならず
駆動時の電力消費が大きい上に、スイッチの温度が上昇

より誤動作現象が引き起され、且つ、復旧が板バネの復
帰力によって行われるため動作が遅いという欠点があっ
た。[Problems to be solved] Among the conventional conductive liquid contact relays mentioned above, the single-side stable conductive liquid contact relay has a built-in conductive liquid contact switch with a movable electrode that has the restoring force of a leaf spring, so it cannot be reversed. In order to maintain the switch, the drive current must continue to flow, which consumes a lot of power during operation, and the temperature of the switch rises and the conductive liquid inside evaporates and condenses, causing malfunctions due to the condensed conductive liquid. This phenomenon is caused, and the recovery is performed by the restoring force of the leaf spring, so there is a drawback that the operation is slow.
両側安定型導電液体接点リレーは反転を繰返す時には、
駆動電流の極性をその都度変化させなければならず、更
に動作が常に板バネの復帰力に抗して行われるため、動
作速度が遅くなったり、電力消費が大きくなるという欠
点があった。When double-sided stable conductive liquid contact relays repeat reversals,
The polarity of the drive current must be changed each time, and furthermore, the operation is always performed against the restoring force of the leaf spring, which has the drawbacks of slow operation speed and increased power consumption.
