Description

Acid-climbing-preventing structure of lead-acid storage battery

Technical Field

The utility model belongs to the technical field of the lead acid battery technique and specifically relates to a lead acid battery acid leakage prevention structure is related to.

Background

After the lead-acid storage battery is used for a period of time, white acidic substances gradually appear on positive and negative poles and connecting wires of the lead-acid storage battery, the pole part of a serious person has the phenomena of liquid leakage, burning loss or corrosion of the root part of the pole, and the industry is generally called acid leakage or seepage.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough and provide a lead acid battery acid leakage prevention structure, this structure has effectively solved utmost point post acid leakage phenomenon, has prolonged lead acid battery's life.

The utility model discloses a realize through following technical scheme: the acid leakage prevention structure of the lead-acid storage battery comprises a lead pole, wherein more than one acid leakage prevention ring is sequentially arranged on the outer side wall of the lead pole from top to bottom;

a copper terminal is embedded in the lead pole, the copper terminal is superposed with the vertical axis of the lead pole, and the copper terminal and the lead pole are cast into a whole in a gravity casting mode;

the outer side of the lead pole is encapsulated by a plastic encapsulating piece in a pressure injection molding mode, the plastic encapsulating piece is made of PP materials, and the plastic encapsulating piece at least wraps the upper end face of the lead pole and the anti-creeping acid ring;

the copper terminal extends out from the upper end face of the lead pole upwards and partially extends out of the plastic encapsulating piece;

the plastic encapsulating piece is encapsulated on the battery cover in a body hot melting mode.

Wherein, preferred, anticreep acid ring sets up quantity and is 8, and every anticreep acid ring thickness is 3mm, and when the vertical interval between every anticreep acid ring was 3mm, plumbous utmost point post anticreep acid effect was best.

Wherein, preferred, the length that the copper terminal stretches out in lead utmost point post sets up to 6mm, and the copper terminal stretches out to set up to 2mm in plastics encapsulating length, has so both satisfied copper terminal and external connecting piece and has connected length, has guaranteed overall structure's stability.

Preferably, a circle of convex part is further arranged on the outer side wall of the plastic packaging part, a circle of extending part corresponding to the convex part is arranged on the battery cover, the extending part extends from the lower end face of the battery cover towards the direction of the convex part, when the battery cover is packaged on the battery jar, the lower end face of the extending part is just fully matched with the upper end face of the convex part, and the design of the convex part and the extending part further improves the sealing performance between the battery cover and the plastic packaging part.

Preferably, the upper end surface of the protruding portion is flush with the upper end surface of the battery case.

Wherein, preferably, the bulge is connected with the extension part through a hot melting mode.

Compared with the prior art, the beneficial effects of the utility model are that:

lead utmost point post and plastics encapsulating adopt the mode of pressure injection molding to encapsulate for lead utmost point post and encapsulating combine very tightly, lead utmost point post sets up eight acid-blocking ring structures, has avoided the inside acidizing fluid of battery to climb up along lead utmost point post, and utmost point post encapsulating adopts the mode of the hot melt of body to link together with the battery cover, and it is integrative to encapsulate with the battery cover, further strengthens anti-acid-climbing effect.
