And an axial through hole is formed in the side wall of the convex edge and is used for filling epoxy resin into the gap cavity. The corrosion of electrolyte to the pole can be effectively isolated in the battery shell, and the service life of the lead-acid battery is further prolonged.

Description

TECHNICAL FIELD

[0001] The utility model relates to lead -acid battery technical field especially relates to a pole post anticorrosive sealing structure for lead -acid battery. BACKGROUND

[0002] At present, lead -acid battery has the characteristics of deep cycle resistance, maintenance free, long service life, battery uniformity is good, is suitable for the environment high low temperature span big feature. Because the application scene of lead -acid battery, generally have the requirement of frequent cycle period, long use period, the pole post is provided with the busbar connected with each pole plate as the carrier lower end of the terminal, the pole post is generally exposed in the pole plate cavity, therefore the electrolyte in the pole plate cavity is very easy to adhere to the pole post, and the electrolyte generally has corrosive, and the pole post is the core area of the current through in the use process of the battery, the concentration of electrolyte adhered to the pole post is increased, thereby the corrosion of electrolyte to the pole post is excited, lead to corrosion accelerates, seriously shortens the service life of battery. SUMMARY

[0003] The utility model discloses a pole post anticorrosive sealing structure for lead -acid battery can effectively reduce the contact of sulfuric acid in the environment and the exposed battery pole post, avoid pole post corrosion, improve the service life of battery.

[0004] In order to realize the above-mentioned purpose, the utility model discloses a technical scheme as follows:

[0005] A pole post anticorrosive sealing structure, including pole post body and pole post sheath, its characterized in that the pole post body lower extreme is solid with the battery pole plate busbar, and the pole post body is cylindrical, and the pole post body top is equipped with a recess for installing the terminal, and the pole post body upper end lateral wall is provided with a certain length of thread downward along the axial direction;

[0006] The pole post sheath is the circular pipe of two ends opening, and the upper port of the pole post sheath is provided with a circle of the convex edge that protrudes inward, and the other end of the pole post sheath is sleeved on the pole post body, and the pole post body top is out of one head from the convex edge, and the inner wall of the pole post sheath and the thread end of the pole post body form the sealed gap cavity, and the lateral wall of the convex edge is provided with the axial through -hole for filling the epoxy resin into the gap cavity.

[0007] Further scheme is: the pole post sheath is ABS plastic material quality.

[0008] The working principle of the utility model is: the pole post sheath is sleeved on the thread of the pole post body, then fills the epoxy resin through the axial through -hole on the convex edge of one end of the pole post sheath in the gap between the pole post sheath and the thread end of the pole post, and forms two stable protection structures on the surface of the pole post body after the epoxy resin solidification.

[0009] The utility model discloses the advantage is: can effectively isolate the corrosion of electrolyte to pole in the battery shell, further improve the service life of lead-acid battery. BRIEF DESCRIPTION OF DRAWINGS
