Abstract
The utility model provides a lithium battery with a positive pole and a negative pole in the same direction. The lithium battery comprises a battery shell, wherein an annular soldering lug is welded at the periphery of a center pole of a battery positive pole, the periphery of the soldering lug is connected with a negative pole of the battery shell, and the diameter of an inner hole of the welding lug is slightly larger than the outer diameter of the center pole. Enough spaces are remained in the positive pole and the negative pole so that short circuit is prevented. The lithium battery has the beneficial effects of simple structure, convenience in installation, and low error rate because the positive pole and the negative pile are arranged at the same end.
Description
Technical field
The utility model relates to the lithium battery field, be specifically related to a kind of positive and negative electrodes in same to lithium battery.
Background technology
At present, general disposable lithium-battery in the process of using all be positive pole at one end, negative pole is at the other end, and is sometimes easily that battery polar is anti-loaded to, damage equipment.Therefore, there to be some overseas enterprises easy for installation in order considering, quick when the design battery compartment, to avoid makeing mistakes, positive and negative electrode is arranged on one side, but structure is comparatively complicated.
Summary of the invention
Technical problem to be solved in the utility model is for existing lithium battery above shortcomings, provide a kind of positive and negative electrodes in same simple in structure to lithium battery.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be:
Positive and negative electrodes in same to lithium battery, comprise battery container, be welded with an annular weld tabs in pole periphery, the center of anode, the periphery of described weld tabs links to each other with the negative pole of battery container, and the diameter of bore of described weld tabs is more bigger than the external diameter of described center pole.
In such scheme, described weld tabs evenly is welded on four points of battery container negative pole boss by spot welding machine.
In such scheme, described weld tabs is stainless steel nickel plating weld tabs.
The utility model is welded with a weld tabs around the pole periphery, center with the positive pole of battery projection, and the weld tabs diameter of bore is larger than center pole external diameter, so that the battery positive and negative electrode leaves sufficient space, prevents short circuit, and reaches the same purpose at one end of positive and negative electrode.
The beneficial effects of the utility model are: simple in structure, easy for installation, positive and negative electrode is difficult for makeing mistakes with at one end.
Description of drawings
Fig. 1 be the utility model positive and negative electrodes in same to the structural representation of lithium battery.
Fig. 2 is the vertical view of Fig. 1.
Among the figure, the 1-battery container; 2-center pole; The 3-weld tabs
Embodiment
Below in conjunction with embodiment and accompanying drawing the technical solution of the utility model is described further:
As shown in Figure 1, positive and negative electrodes in same described in the utility model to lithium battery, comprise battery container 1, be welded with an annular weld tabs 3 in pole 2 peripheries, the center of anode, the periphery of described weld tabs 3 links to each other with the negative pole of battery container, and the diameter of bore of described weld tabs 3 is more bigger than the external diameter of described center pole 2.
Described weld tabs 3 evenly is welded on four points of battery container 1 negative pole boss by spot welding machine.
Described weld tabs 3 is stainless steel nickel plating weld tabs.
The utility model bossing weldering a slice around the anode end is evenly put four points with spot welding machine with weld tabs 3 and battery boss and is got final product with the stainless steel nickel plating weld tabs of endoporus.Weld tabs 3 diameter of bores are larger than center pole 2 external diameters, so that the battery positive and negative electrode leaves sufficient space, prevent short circuit, and reach the same purpose at one end of positive and negative electrode.
Above-described only is preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalence of therefore doing according to the utility model claim changes, and still belongs to protection range of the present utility model.
