Abstract
The utility model relates to a button cell with a dot surface, which is provided with a positive metal casing, a negative metal casing matched with the positive metal casing, and a sealing ring integrated with the negative metal casing.,. A plurality of projections are uniformly distributed on the negative metal casing. The button cell with the dot surface is fine in contact performance, scratches on the surface of the batter are reduced, and strength of a negative electrode is increased.
Description
Technical field
The utility model relates to the technical field of button cell, the site face button cell that especially a kind of contact is good.
Background technology
Generally all be planar structure on the negative pole metal shell of traditional button cell, the phenomenon of loose contact in use usually can appear in battery, and the user just might contact after need pulling battery, has caused great inconvenience to the user.
Because the negative pole metal shell is a planar structure, also can makes battery surface produce cut, thereby influence the contact performance of battery.
The utility model content
The technical problems to be solved in the utility model is: in order to solve the problem in the above-mentioned background technology, the utility model provides a kind of contact performance good, is difficult for producing the site face button cell of cut.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of site face button cell, the negative pole metal shell that has the cathode metal housing and be complementary with it, and with the into a single integrated structure sealing ring of negative pole metal shell, be evenly distributed with some projectioies on the negative pole metal shell.
Further, the projection that is evenly distributed on the negative pole metal shell is circle.
The beneficial effects of the utility model: be evenly distributed with some projectioies on the negative pole metal shell in the face button cell of site of the present utility model, these projectioies can increase the contact performance of battery, and the probability that occurs of the cut that has reduced battery surface, also strengthened the intensity of negative pole metal shell simultaneously.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a front view of the present utility model;
Fig. 2 is an end view of the present utility model.
Among the figure 1, the cathode metal housing, 2, the negative pole metal shell, 3, sealing ring, 2-1, projection.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of site face button cell as depicted in figs. 1 and 2, the negative pole metal shell 2 that has cathode metal housing 1 and be complementary with it, and with the into a single integrated structure sealing ring 3 of negative pole metal shell 2, be evenly distributed with some protruding 2-1 on the negative pole metal shell 2, these protruding 2-1 are circular.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
