Embodiment

Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described further：

, it is necessary to explanation in description of the present utility model, term " " center ", " on ", " under ", it is "left", "right", " perpendicular Directly ", the orientation of the instruction such as " level ", " interior ", " outer " or position relationship are based on orientation shown in the drawings or position relationship, are only Described for the ease of description the utility model and simplifying, rather than instruction or imply signified position or element must have it is specific Orientation, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.

, it is necessary to which explanation, unless otherwise clearly defined and limited, term " are pacified in description of the present utility model Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integratedly Connection；Can be mechanical connection or electrical connection；Can be joined directly together, can also be indirectly connected by intermediary, It can be the connection of two element internals.For the ordinary skill in the art, it is above-mentioned that concrete condition understanding can be regarded Concrete meaning of the term in the utility model.

As shown in figure 1, a kind of band consolidate extreme ear structure positive and negative electrodes in same to draw battery, including battery case 3, battery and Cover plate 6, battery are arranged on inside battery case 3, and cover plate 6 is covered at battery case upper opening, and the installation of the top of cover plate 6 is drawn in the same direction The positive pole ear 1 that goes out, negative lug 2, positive pole ear 1, the afterbody of negative lug 2 are electrically connected battery both positive and negative polarity, positive pole pole Ear 1, the upper section of negative lug 2 are bent into sophisticated cattle horn shape.

Embodiment 1 as shown in Figure 2, positive pole ear, the kink overbending direction of negative lug are on the contrary, kink is conllinear；Such as Embodiment illustrated in fig. 32, positive pole ear, the kink overbending direction of negative lug are on the contrary, kink is relative；Implement as shown in Figure 4 Example 3, positive pole ear, the kink overbending direction of negative lug are the positive pole ear 1 of sophisticated cattle horn shape, negative on the contrary, kink is parallel The a variety of conversion of arrangement mode, shape and structure of pole lug 2, suitable for the installation requirement of different size, use range is wide, meets peace Reload request.

Specifically, as it can be seen in figures 5 and 6, the structure 2 of the positive pole ear 1, negative lug is identical, positive pole ear 1, negative pole Lug 2 is made up of the plate-like portion 4 and kink 5 that are integrally connected respectively, and plate-like portion 1 is riveted at the upper cover plate 6 of battery case 3, lid Plate 6 includes soft-slab and plank, rivet sequentially pass through from top to down soft-slab, plank and plate-like portion is riveted on soft-slab, Kink 5 is folded upward at into sophisticated cattle horn shape, and kink 5 includes transitioning end 51 and tip 52, the bottom connecting plate shape of transitioning end 51 Portion 4 is bent laterally, the top of transitioning end 51 connection tip 52, the inside lateral bending folding of tip 52, the outward bending of transitioning end 51 and it is sophisticated 52 inside lateral bendings folding collective effects, make lug clamping more firm, tip 52 fully with attachment CONTACT WITH FRICTION.

As shown in Figure 7 and Figure 8, the outer circumferential side of battery case 3 rolling waistband 7, banding consolidate battery position, ensure that it does not shake It is dynamic, and the bottom of battery case 3 is provided with explosion-proof trace 8, explosion-proof trace 8 can be variously-shaped preferably Y shape or X-shaped, in battery is unstable During the increase of portion air pressure, gas expansion washes the explosion-proof trace 8 (remaining part thickness is thinner with respect to battery case for explosion-proof trace) of rupture open, gas from Discharged at the explosion-proof trace 8 of the bottom of battery case 1, reach discouraged purpose, further improve security, prevent battery from drastically exploding.

Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to Assert that specific implementation of the present utility model is confined to these explanations, for the ordinary skill of the utility model art For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded To belong to the scope of protection of the utility model.
