Prevent malfunction of lead accumulator indicator caused by foreign matter contamination

摘要

The present invention relates to a structure for preventing malfunction of a lead acid battery indicator due to contamination of a foreign material, and more specifically, an indicator ball when foreign matter in the electrolyte such as oil generated during the manufacture of a separator and scattering floating substances during circulation of the electrolyte is adsorbed to the space inside the indicator. By preventing the movement of the indicator to prevent the movement of the indicator, even though it is a normal lead-acid battery, it is indicated as abnormal, so it improves the problem that causes confusion to the user, and a plurality of through holes 410 are fixed to the lower and both sides of the lower holder formed on the lower side of the indicator. By forming a microporous filter portion for forming only the electrolyte solution with the contaminants filtered and remaining around the specific gravity ball, each acts as a filter to prevent the inflow of foreign substances and through capillary action, only pure electrolyte solution can remain in the indicator indication space. Foreign matter It relates to a structure for preventing malfunction of a lead acid battery indicator due to contamination. Through the present invention, even though it is a normal lead-acid battery in the prior art, it is indicated as abnormal, thereby solving the problem of causing confusion to the user.
