Abstract
The utility model provides a storage battery, relating to the storage battery technical field, in particular to the polar group connection technical field. A plurality of separating grooves are arranged inside a battery groove, and each separating groove is provided with a polar group consisting of a negative plate, a positive plate, a clapboard and a convergent plate. The storage battery is characterized in that two convergent plates corresponding to two polar groups connected in series are welded and fixed directly. The convergent plates connected in series are welded and fixed directly without the graded seal of a bridge and the bridge welding, thereby not only saving materials but also saving two welding processes; moreover, the reduction of the welding points avoids the open circuit caused by a plurality of the welding points so that the product quality is better guaranteed.
Description
Technical field
The utility model relates to a kind of technical field of storage battery, particularly utmost point group's wherein interconnection technique field.
Background technology
As everyone knows, storage battery mainly is made up of the utmost point group in the battery case, electrolyte (or glue) and splicing ear, some interval troughs are set in battery case, the positive plate that in each interval trough, negative plate is set and isolates at interval by dividing plate, the upper end of each negative plate and positive plate is welded on respectively on the cylinder manifold, and the corresponding cylinder manifold of interval trough is in order to form series connection, a L-shaped bridge also will be welded again in each cylinder manifold upper end, and two cylinder manifolds are essential with two close bridge bridge weldings more mutually.The multiple spot welding of prior art not only increases production cost, also increases the production difficulty, as long as one of them pad is not firm, just opening circuit of whole piece circuit can occur, directly influences the useful life of storage battery.
The utility model content
The utility model purpose is to design and a kind ofly makes things convenient for economizing type production, can improve the storage battery storage battery in useful life.
Some interval troughs are set in the utility model battery case, the one group of utmost point group who comprises that negative plate, positive plate, dividing plate, cylinder manifold are formed is set in each interval trough, and directly welding is fixing mutually between corresponding two cylinder manifolds of two groups of utmost point groups that it is characterized in that connecting mutually.
Two cylinder manifolds of connecting mutually of the utility model directly weld fixing, need not only to have saved material by bridge and bridge welding transition welding, also saved the twice welding sequence, and the minimizing of this pad, that can avoid that many pads cause opens circuit, and makes product quality more secure.
The utility model is divided into marginal plate with negative plate and bears two kinds of middle plates, and marginal plate arranges that near interval trough negative middle plate arranges that away from interval trough the thickness ratio of plate and marginal plate is 1: 0.85～0.9 in described the bearing.Have only 70% owing to be close to the utilance of two marginal plate active materials of each interval trough layout, so the marginal plate of attenuate is not only saved the plumbous amount of the consumption of marginal plate, saves cost, but also saves the space, promote the consumption of active material, more can therefore improve the utilance of positive and negative pole active matter.
Described negative middle plate and the preferred thickness ratio of marginal plate are 1: 0.875.
In addition, interval trough of the present utility model can be single setting, can make the attenuate of battery case thickness, promotes storage battery bearing capacity to big electric current when electric motor car climbing or load.Also convenient welding more helps the machinery operation of welding automatically, can improve the quality and the speed of welding of product.In addition, also be beneficial to assembling, be beneficial to positive and negative pole plate is increased, make cylinder manifold be higher than the interval trough height, promote capacity, the life-span of storage battery.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is arranged in the interior structural representation of battery case for utmost point group.
Fig. 3 is utmost point group's a structural representation.
Embodiment
As shown in Figure 1, 2, 3, storage battery mainly is made up of battery case 1, battery cover 12, cover plate 11, cylinder 5, sealing ring 6, bottoming glue 7, signal paint 8, binding post 9, Capsule 10, positive plate 2, dividing plate 4, negative plate plate 3, cylinder manifold 13.
Battery case 1 interior single six interval troughs that are provided with are provided with the one group of utmost point group who comprises that negative plate 3, positive plate 2, dividing plate 4, cylinder manifold 13 are formed in each interval trough.The positive plate 2 that negative plate 3 is set at interval and isolates in each interval trough by dividing plate 4,3 fens marginal plate 3-1 of negative plate and negative in two kinds of plate 3-2, marginal plate 3-1 arranges near interval trough, plate 3-2 arranges away from interval trough in negative, the upper end of each negative plate 3 and positive plate 2 is welded on respectively on the cylinder manifold 13, the corresponding cylinder manifold 13 of interval trough.
Directly welding is fixing mutually between corresponding two cylinder manifolds of two groups of utmost point groups of the mutual series connection of each interval trough.
Wherein, the thickness ratio of negative middle plate and marginal plate is 1: 0.85～0.9.In this example, negative in the thickness of plate be 1.6mm, marginal plate thickness be 1.4mm.
Claims (4)
1, a kind of storage battery, comprise battery case, some interval troughs are set in the battery case, the one group of utmost point group who comprises that negative plate, positive plate, dividing plate, cylinder manifold are formed is set in each interval trough, directly welding is fixing mutually between corresponding two cylinder manifolds of two groups of utmost point groups that it is characterized in that connecting mutually.
2, according to the described storage battery of claim 1, it is characterized in that described negative plate by marginal plate and negative in plate forms, marginal plate arranges near interval trough, negative in plate arrange that away from interval trough the thickness ratio of described negative middle plate and marginal plate is 1: 0.85～0.9.
