Abstract
The utility model discloses a small storage battery which comprises a casing. An upper cover is arranged above the casing, and at least one electrode plate group is arranged in the casing and soaked in electrolyte in the casing. The electrode plate group leads a pole out, and a wiring terminal is fixed on the pole. The wiring terminal is led out of the front end of the upper cover after bent for many times so that the electrolyte cannot be leaked through the position of the wiring terminal, the sealing performance is reinforced, and leakage is avoided. Only glue filling in one time is needed after the structure is adopted, a production process is simplified, and the cost is effectively reduced.
Description
Technical field
The utility model relates to a kind of battery, the good small battery of particularly a kind of airtight performance.
Background technology
In recent years, be accompanied by the development of various portable electric appts,, researched and developed the storage battery of the hermetic type that becomes its driving power as one of important Primary Component.The storage battery of existing hermetic type is to adopt at least one electrode plate groups that is immersed in the electrolyte as power supply; Electrode plate groups is immersed in the electrolyte, and electrode plate groups is provided with outward extending binding post, and binding post upwards directly passes the through hole that upper cover has and is drawn out to outside the battery; The through hole that is potted in upper cover through environmental protection glue secondary prevents battery leakage; Because binding post is directly to pass loam cake, electrolyte is revealed away along binding post easily, and human body is worked the mischief; And the production of this storage battery need seal complex production process, cost height through twice encapsulating.
The utility model content
In order to overcome the deficiency of prior art, the utility model provides a kind of airtight performance good small battery, can effectively prevent the phenomenon of leakage of storage battery, and manufacture craft is simple, and cost is low.
The utility model solves the technical scheme that its technical problem adopted:
A kind of small battery; Comprise housing, the housing top is provided with loam cake, is provided with at least one electrode plate groups in the housing; Electrode plate groups is immersed in the electrolyte in the housing; Said electrode plate groups is outwards drawn pole, is fixed with binding post on the said pole, and said binding post is repeatedly drawn from the loam cake front end after the bending.
Preferably, the downward bending of said binding post is also stretched out housing bottom loam cake, and bending again makes progress.
The beneficial effect of the utility model is: this small battery has been strengthened the sealing of battery because its binding post through repeatedly drawing from loam cake after the bending, can not reveal electrolyte through the binding post place, and the situation of having stopped leakage occurs; And adopt this structure only need carry out one time embedding glue, and simplify production technology, effectively reduce cost.
A kind of improvement as technique scheme; Be provided with the electrode plate groups of two series connection in the said housing; Be provided with dividing plate in the said housing, said dividing plate is divided into two not connected groove positions with the enclosure interior spatial, and said two electrode plate groups separately are arranged in the groove position; The setting of groove position makes two electrode plate groups keep independent, two independently the electrode plate groups series connection improve cell output voltage.
Further; Said loam cake corresponding groove position is provided with liquid injection hole, and said liquid injection hole is outside equipped with the capping that is used to seal, and said liquid injection hole is arranged on the recess place of loam cake; Said loam cake is provided with the baffle plate that is used to protect liquid injection hole; Liquid injection hole annotates electrolyte toward the battery the inside after being used in cell package, and the situation that can protect liquid injection hole and prevent leakage that is provided with of capping and baffle plate occurs.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the perspective view of the utility model;
Fig. 2 is the fractionation structure chart of the utility model;
Fig. 3 is the internal structure sketch map of loam cake;
Fig. 4 is the structural representation of binding post.
Embodiment
Referring to figs. 1 through Fig. 4, a kind of small battery of the utility model comprises housing 1; Housing 1 top is provided with loam cake 2, is provided with at least one electrode plate groups 3 in the housing 1, and electrode plate groups 3 is immersed in the electrolyte in the housing 1; Said electrode plate groups 3 is outwards drawn pole 31, is fixed with binding post 4 on the said pole 31, and is preferred; Said binding post 4 downward bendings are also stretched out housing 1 from loam cake 2 bottoms, and upwards bending forms terminals again, this small battery since its binding post 4 through repeatedly drawing from loam cake 2 after the bending; Electrolyte can not be revealed through binding post 4 places, strengthened the sealing of battery, the situation of having stopped leakage occurs.
Further; Preferably be provided with the electrode plate groups 3 of two series connection in the housing 1; Be provided with dividing plate 11 in the housing 1, dividing plate 11 is separated into 12, two electrode plate groups in two not connected groove positions with housing 1 inner space and opened in 3 minutes and be arranged in the groove position 12; The setting of groove position 12 makes two electrode plate groups 3 keep independent, two independently electrode plate groups 3 series connection to improve the output voltage of battery.
Further; Said loam cake 2 corresponding groove positions 12 are provided with liquid injection hole 21, and said liquid injection hole 21 is outside equipped with the capping 22 that is used to seal, and said liquid injection hole 21 is arranged on the recess place of loam cake 2; Said loam cake 2 is provided with the baffle plate 5 that is used to protect liquid injection hole 21; Liquid injection hole 21 annotates electrolyte toward the battery the inside after being used in cell package, and the situation that can protect liquid injection hole 21 and prevent leakage that is provided with of capping 22 and baffle plate 5 occurs.
The design's small battery can prevent effectively that the situation of leakage from occurring because its binding post 4 adopts the labyrinth type package design, and the production process of this battery only need carry out the embedding of a glue, simplifies production technology, reduces production costs.
The above is merely the preferential execution mode of the utility model, as long as realize that with basic identical means the technical scheme of the utility model purpose all belongs within the protection range of the utility model.
