Abstract
A lead-acid storage battery comprises a battery tank body, and a cover body adaptive to the battery tank body, wherein electrode plates and bus bars are arranged in the battery tank body; poles are arranged on the electrode plates and are connected with the electrode plates; the bus bars are arranged at the middle positions on the tops of the electrode plates; the tops of the bus bars extend out of the tank body; a boss is arranged on the rear end of the top surface of the cover body; a liquid injection hole is formed in the rear end of the boss; two bilaterally symmetric through-holes are formed in the front end of the cover body, and are adaptive to the poles in position; and an accommodating cavity for accommodating the bus bars can be formed when the cover body is combined with the battery tank body. According to the lead-acid storage battery, the position of a conventional acid injection hole is formed on the front end of the top surface of the cover body instead of the middle part; a partial pole groove is removed; and the middle part on the back side of the cover body is available to place the bus bars after monomers are connected, and is sealed by epoxy resin. The lead-acid storage battery provided by the utility model can increase the height of electrode plates without changing the boundary dimension of the battery, thereby improving discharge performance of the battery.
Description
Technical field
The utility model relates to the storage battery field, specifically refers to a kind of lead acid accumulator.
Background technology
Along with the requirement of electricity consumption product more and more comes high, thereby the performance to lead acid accumulator is also had higher requirement, and general electricity consumption product stays the space of giving storage battery limited, the discharge performance of original storage battery can not satisfy daily needs, thereby how improve the discharge performance of storage battery in the confined space, become the emphasis of numerous researchs.
The utility model content
The purpose of this utility model is to provide a kind of storage battery that can improve discharge performance under the prerequisite of the size that keeps original battery effectively.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of lead acid accumulator, comprise battery cell body and the lid adaptive with described battery cell body, be provided with pole plate and bus-bar in the described battery cell body, described pole plate is provided with pole, and be connected with described pole, described bus-bar places the centre position at the top of described pole plate, and described cell body is stretched out at the top of described bus-bar; The rear end of the end face of described lid is provided with a boss, and the rear end of described boss is provided with liquid injection hole, and the front end of described lid is provided with two symmetrical through holes, and the position of this through hole and described pole is suitable; The medium position of the bottom surface of described lid is vacant, and described lid can form the container cavity of taking in described bus-bar when cooperating with described battery cell body.
Further, the surface coverage of described bus-bar has the epoxy gum layer.
Further, the height of described pole plate is 8/9-9/10 of the cell body degree of depth.
The utility model is with traditional sour hole site is changed into the end face of lid by the centre front end that adds, and cancelled polar biased post groove and cancelled, centre position, the lid back side is vacant to place the bus-bar after monomer connects, seal with epoxy resin simultaneously, the utility model can not change the size of battery profile, increase height of pole plate, improve the discharge performance of battery.

Fig. 2 is the vertical view of lid;
Fig. 3 is the upward view of lid.
Embodiment
Now by reference to the accompanying drawings, describe the utility model in detail.
With reference to accompanying drawing 1, a kind of lead acid accumulator, comprise battery cell body 1 and the lid 2 adaptive with battery cell body 1, be provided with pole plate 11 and bus-bar 12 in the battery cell body 1, it is high that the height of the storage battery that the aspect ratio of pole plate 11 is traditional is wanted, the height of pole plate 11 is 8/9-9/10 of the cell body degree of depth, pole plate 11 is provided with pole (not marking among the figure), and be connected with pole, bus-bar 12 places the centre position at the top of pole plate 11, and cell body 1 is stretched out at the top of bus-bar 12, promotes the position of bus-bar simultaneously by the height that increases pole plate 11, thereby improve the discharge performance of battery, improve the discharge performance of battery.
With reference to accompanying drawing 2 and accompanying drawing 3, the rear end of the end face of lid 2 is provided with a boss 21, and the rear end of boss 21 is provided with liquid injection hole 22, and the front end of lid 2 is provided with two symmetrical through holes 23, and this through hole 23 is suitable with the position of pole; The medium position of the bottom surface of lid 2 is vacant, can form the container cavity of taking in bus-bar 12 when lid 2 cooperates with battery cell body 1, seals with epoxy resin simultaneously, is about to bus-bar 12 and is sealed in the epoxide-resin glue, has reached the effect of sealing.
Above-described the utility model execution mode does not constitute the restriction to the utility model protection range.Any modification of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the claim protection range of the present utility model.
Claims (3)
