Abstract

PURPOSE:To restrict electric consumption and aim at increasing action speed by providing a differentiation circuit element for converting inputted rectangular wave current into positive/negative differential wave current to energize a drive coil. CONSTITUTION:At the bottom of a sealed container 4 enclosing conductive liquid 3 are fixed a needle 2a and a freely rotatable pivot part 2b, and at the top are provided fixed electrodes with the top end of the needle 2a between them. At the electrodes 1, 1 are fixed permanent magnets 5, 5 respectively. A drive coil 6 is provided having a container 4 inserted, so the needle 2a is magnetized with its polarity switched between N and S poles by sending a proper positive/negative current to the coil 6. A differentiation circuit element 7 takes rectangular wave current from a rectangular wave generator 8 and converts it into positive/negative differential wave current so as to energize the coil 6. The needle 2a rotates about the pivot part 2b and is switched by positive/negative current corresponding to the rectangular wave from the generator 8. Current consumption is thus restricted, while high speed action is enabled.

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.

[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.

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.

Furthermore, in double-sided stable conductive liquid contact relays, the polarity of the drive current is changed and reversed.

[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.

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.
