Embodiment Construction

[0015] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0016] [Schematic structure of lead storage battery 100]

[0017] figure 1 It is a perspective view which shows the lead acid battery 100 which concerns on embodiment of this invention. like figure 1 As shown, the lead-acid battery 100 includes: a plurality of electrode plates (not shown); an electrolyte solution (not shown); Cover 15.

[0018] The electric tank 12 is a substantially rectangular parallelepiped-shaped container having an opening on the upper surface, and is formed of, for example, synthetic resin. The cell 12 has partition walls. The inside of the cell is partitioned into a plurality of cells arranged in a predetermined direction by partition walls. An electrode plate group is arranged in each of the plurality of cells.

[0019] The opening of the cell 12 is closed by a cover 15 having a shape corresponding to the opening. ...

Abstract

The liquid port plug (18) is provided with a head part (35), a cylindrical part (36) extending from the head part (35), and a filter (34) provided on the inside of the cylindrical part (36), the cylindrical part (36) is provided with a through hole (43) that connects the inside and the outside of the cylindrical part (36), the through hole (43) has an opening in the inner peripheral surface of the cylindrical part (36), and the filter (34) is provided so as to close the opening of the through hole (43).

Description

technical field [0001] The present invention relates to a liquid port plug for a lead storage battery and a lead storage battery. Background technique [0002] Lead-acid batteries are used in various applications in addition to automotive and industrial use. The lead acid battery includes an electrode plate group in which a positive electrode plate and a negative electrode plate are stacked on each other with a separator interposed therebetween. In the lead acid battery, the electrode plate group is immersed in the electrolyte solution held in the cell, and the opening of the cell is sealed with a lid. Among such lead storage batteries, there is a lead storage battery in which a liquid port plug for replenishing the electrolyte solution is provided in the lid. The liquid port plug includes: a cylindrical body whose lower end is open; and a head that closes the upper end of the cylindrical body. In addition, among the liquid port plugs, there is a liquid port plug in which...
