Description
Technical field
The present invention relates to a kind of accumulators, and in particular to a kind of lead-acid accumulator and electric vehicle.
Background technology
The mounting structure generally use of the positive terminal in lead-acid accumulator or negative terminal (i.e. battery terminal) is such as at present
Lower structure：As shown in figure 8, the mounting structure of positive terminal includes positive terminal 6, sealing ring 14 is linked together just with bus-bar 3
It holds post terminal guiding 16 and is arranged in the upper surface of battery case lid 2 and terminal glue groove 12 corresponding with anode post terminal guiding, and
The bottom surface of terminal glue groove is equipped with sealing ring mounting groove 13；Evacuation through-hole 15 is additionally provided on the bottom surface of the sealing ring mounting groove, and
Anode post terminal guiding passes through evacuation through-hole to be located in terminal glue groove.
The packaging technology of positive terminal or negative terminal is as follows in lead-acid accumulator at present：It is sleeved on firstly the need of by sealing ring
On anode post terminal guiding or negative terminal post terminal guiding, and sealing ring is made to be placed in sealing ring mounting groove, it is using sealing ring that evacuation is logical
Hole envelope hides；Then, by positive terminal or negative terminal by weld directly with the anode post terminal guiding or negative terminal in terminal glue groove
Post terminal guiding is connected；Followed by casting glue being injected in terminal glue groove, by positive and negative electrode terminal and positive and negative end post terminal guiding
Welding position embedding, to the packaging technology of outside positive and negative electrode terminal.
On the other hand, the packaging technology of positive terminal or negative terminal is in battery case lid and electricity in lead-acid accumulator at present
Pond box body glue is honored as a queen progress.Battery case lid and battery box glue envelope technique are to inject casting glue in the glue groove of battery case lid,
Then it is buckled in the port of battery box is directed downwardly on battery case lid, battery case lid and battery box is completed after embedding adhesive curing
Glue seals.
At present in lead-acid accumulator the glue of battery case lid and battery box envelope technique and positive terminal or negative terminal envelope
Dress technique can not carry out in the technique with along with, they must be divided into the successively operation of twice technique, this not only adds
Processing step reduces generation efficiency；And the encapsulating structure of this kind of battery positive voltage terminal or negative terminal is complicated at present, operates
It is cumbersome, since evacuation through-hole is located at the battery case surface of accumulator, in order to avoid in terminal glue groove when encapsulating, terminal glue groove
Interior casting glue drops onto the electricity of accumulator by the gap between anode post terminal guiding or negative terminal post terminal guiding and evacuation through-hole
In the slot of pond；It thus needs to be sleeved on sealing ring by manually before positive and negative electrode terminal is welded with positive and negative end post terminal guiding positive and negative
It holds between post terminal guiding and sealing ring mounting groove, will avoid through-hole envelope using sealing ring hides.Due to current this kind of battery positive voltage
Terminal or negative terminal need to install sealing ring during the installation process, and this not only adds installation procedures, and in practical generation
It often will produce operator's work neglected loading sealing ring in the process or sealing ring installation be not in place, hidden without envelope completely and allow through-hole, led
It causes in terminal glue groove when encapsulating, the casting glue in terminal glue groove is logical by anode post terminal guiding or negative terminal post terminal guiding and evacuation
Gap between hole drops onto in the battery case of accumulator, influences the normal use of accumulator.
