Description of the drawings
Fig. 1 is the lead-acid accumulator part section structural representation of the application.
Specific implementation mode
The utility model is described in further detail below by specific implementation mode combination attached drawing.
The utility model embodiment provides a kind of lead-acid accumulator, and Fig. 1 is the part section knot of the lead-acid accumulator
Structure schematic diagram, it is obvious that the right half part of sectional view is not shown in the lead-acid accumulator and provides a left side for sectional view
Half part has symmetrical structure；As shown in Figure 1, the lead-acid accumulator, including：Battery case 11, battery cover 12, Duo Geji
Group 13, pole 14 (including positive terminal and negative terminal, Fig. 1 in illustrate only one of pole) and terminal 15 (including anode
Terminal and negative terminal illustrate only one of terminal in Fig. 1)；Wherein,
Each pole group 13 is made of positive plate, negative plate, partition board, bus-bar, is marked with electrolyte in the pole group, often
Ge Ji groups are fixed in battery case, specifically, each pole group is fixed in battery case 11 cell negative terminal, it is adjacent
Liang Geji groups 13 between be connected by the connection strap 16 of cast welding straight forming, connection strap 16 is connected to the top of pole group 13
Close to marginal position.Specifically, connection strap 16 is also direct cast welding molding connection with pole group 13.
In another optional embodiment of the utility model, when the height of the pole group 13 is less than cell negative terminal
When height, the lead-acid accumulator further includes：Ethylene-vinyl acetate copolymer (EVA) 17, the EVA 17 are padded in cell negative terminal
Bottom is used to support the pole group 13 being fixed in cell negative terminal so that with pole group 13 cast welding molding for connecting consecutive roots
The connection strap 16 of group 13 reaches can be most short under working condition, reduces lead loss, improves the antivibration kinetic force of battery, it is ensured that battery
Starting performance；The pole group 13 that different height can be designed according to 17 thickness of EVA, produces the battery of different capabilities to meet client
Demand makes shell obtain maximization and efficiently uses.
In a kind of optional embodiment of the utility model, the battery case 11 and battery cover 12 are all made of high temperature resistant shape
Polypropylene (PP) high molecular material of change, and the battery case 11 uses heat-seal with battery cover 12, to effectively avoid high temperature
Battery case yielding disadvantage when being used in environment increases battery case cap intensity and heat-resisting ability.
Preferably, it after battery case 11 and battery cover 12 encapsulate, is welded using soldering iron after pole 14 and the cooperation of terminal 15.
