Abstract
The utility model relates to a battery. The batter comprises a positive electrode plate, a negative electrode plate and a battery casing (3), wherein the positive electrode plate and the negative electrode plate have a flake shape and sandwich a diaphragm therebetween; the positive electrode and the negative electrode plate are stacked and wound together to form a cylindrical battery electrode group (2) and are mounted in the battery casing (3); and an elastic device, such as an elastic steel plate, is arranged on the inner side of the cylindrical battery electrode group (2) for expanding the battery electrode group and keeping the battery electrode tightly attached to the inner wall of the battery casing (3). The battery electrode group (2) is tightly pressed onto the inner wall of the battery casing (3) by the elastic device so as to achieve more stable and firm connection with the battery casing (3). Accordingly, the battery electrode group (2) has little possibility of looseness in vibratory environment.
Description
Technical field
The utility model relates to a kind of battery, especially a kind of battery of being made up of battery utmost point group and battery case.
Background technology
Common batteries generally is made up of electrolyte, battery utmost point group, battery container.Battery utmost point group is stacked together by anode pole piece and cathode pole piece and constitutes, and separates with barrier film between two pole pieces.Battery utmost point group is wound into cylindric being installed in the battery container.In the bigger environment of vibrations, battery utmost point group is fixing firm inadequately, battery utmost point group is easily loosening, with battery container generation relative displacement, even come off from battery container, cause and open circuit.
The utility model content
Technical problem to be solved in the utility model provide a kind of battery utmost point group and battery container fixed, the battery that is difficult for opening circuit.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of battery, comprise anode pole piece, cathode pole piece and battery container, described cathode pole piece and anode pole piece are sheet, be provided with barrier film between the two, cathode pole piece and anode pole piece be stacked, be wound on and form cylindrical battery utmost point group together, and be installed in the battery container, described cylindrical battery utmost point group inboard is provided with the elastic device that makes battery utmost point group radial dilatation and cling to the battery container inwall.
Further, described elastic device is a spring steel plate, and spring steel plate is wound into cylindric, is located at described cylindrical battery utmost point group inboard.
The beneficial effects of the utility model are: because the effect of elastic device, battery utmost point group can be extruded and be close on the battery container inwall.As being wound into the cylindric battery utmost point group of inserting when spring steel plate when inboard, spring steel plate opens naturally, pushes battery utmost point group laterally, makes battery utmost point group radial dilatation be close to the battery container inwall.Be connected more firmly, firm between battery utmost point group and the battery container like this, in vibration environment, battery utmost point group is difficult for loosening, and battery can stably be powered.
Description of drawings
Fig. 1 is the utility model embodiment cylindrical battery cross-sectional view;
Fig. 2 is the longitudinal section of the utility model embodiment battery;
In the accompanying drawing, the parts of each label representative are respectively: 1, spring steel plate, 2, battery utmost point group, 3, battery container.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described.
A kind of battery of battery described in the utility model, comprise anode pole piece, cathode pole piece and battery container 3, described cathode pole piece and anode pole piece are sheet, be provided with barrier film between the two, cathode pole piece and anode pole piece be stacked, be wound on and form cylindrical battery utmost point group 2 together, and be installed in the battery container 3.As shown in Figure 1 and Figure 2, cylindrical battery utmost point group 2 inboards are provided with the elastic device that makes battery utmost point group 2 radial dilatation and cling to battery container 3 inwalls.This elastic device can be a spring steel plate 1, and spring steel plate 1 is wound into cylindric, and is located at described cylindrical battery utmost point group 2 inboards in the mode that the center of circle overlaps.
Because steel plate 1 has certain elasticity, steel plate 1 is wound into when cylindric, and the tension force of circumferencial direction is outward arranged, and pushes battery utmost point group 2 laterally, makes battery utmost point group 2 radial dilatation and is close to battery container 3 inwalls.Being connected between battery utmost point group 2 and the battery container 3 is more firm, firm, and in vibration environment, battery utmost point group 2 is difficult for becoming flexible, coming off, and battery can stably be powered.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
Claims (2)
1. battery, comprise anode pole piece, cathode pole piece and battery container (3), described cathode pole piece and anode pole piece are sheet, be provided with barrier film between the two, cathode pole piece and anode pole piece be stacked, be wound on and form cylindrical battery utmost point group (2) together, and be installed in the battery container (3), it is characterized in that: described cylindrical battery utmost point group (2) inboard is provided with the elastic device that makes battery utmost point group (2) radial dilatation and cling to battery container (3) inwall.
2. battery according to claim 1 is characterized in that: described elastic device is spring steel plate (1), and spring steel plate (1) is wound into cylindric, is located at described cylindrical battery utmost point group inboard.
