Abstract
The utility model discloses a kind of button cell of high leakproofness, including battery core, the shell being coated on outside battery core, the shell includes the inner casing being coated at the top of battery core with side, it is coated on the shell of battery core bottom and inner casing side, the place of joining of the shell and inner casing is provided with sealing ring, and the bottom of the interior shell side wall has flaring outwardly, and the flaring squeezes sealing ring and forms o-ring groove.The leakproofness of battery is realized and reinforced to the setting of the flaring so that the contact between inner casing and shell and sealing ring is even closer.
Description
Technical field
The utility model relates to a kind of batteries, are to be related to a kind of button cell of high leakproofness more specifically.
Background technique
For current most of battery producers when making cylindrical battery, shell uses circular metal shell.Referring to FIG. 3, existing
The sealing structure of some cylindrical batteries is divided into three layers: inner casing 80, shell 70 and sealing ring 30.The sealing of battery uses the angle R
Sealing technique, however existing technological means to the measurement at the angle R be not very precisely, cannot control battery seal leakproofness completely.Therefore R
Angle sealing tech cannot reliably solve sealing problem.
Utility model content
To overcome drawbacks described above in the prior art, the utility model provides a kind of button cell of high leakproofness.
To achieve the above object, the utility model provides a kind of button cell of high leakproofness, including battery core, is coated on electricity
Shell outside core, the shell include the inner casing for being coated at the top of battery core and side, are coated on battery core bottom and inner casing side
The place of joining of shell, the shell and inner casing is provided with sealing ring, and the bottom of the interior shell side wall has flaring outwardly, described
Flaring squeezes sealing ring and forms o-ring groove.
Preferably, the sealing ring includes being located at the sealing ring body of shell and the inner casing place of joining and being installed in close
Bending part of the seal ontology bottom end towards inner bending.
Preferably, the bottom of the side wall of the inner casing is installed in the top surface of bending part.
Preferably, the width expanded outwardly that is flared is 0.03mm.
Preferably, the height of the flaring is 2mm.
Preferably, the shell is metal-back.
Compared with prior art, the utility model has the beneficial effects that:
The utility model includes battery core, the shell being coated on outside battery core, and the shell is coated at the top of battery core and side
The inner casing in face, is coated on the shell of battery core bottom and inner casing side, and the place of joining of the shell and inner casing is provided with sealing ring, institute
The bottom of interior shell side wall is stated with flaring outwardly, the flaring extruding sealing ring formation o-ring groove.The flaring is set
It sets so that the contact between inner casing and shell and sealing ring is even closer, realizes and reinforce the leakproofness of battery.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is this
Some embodiments of utility model, for those of ordinary skill in the art, without creative efforts, also
Other drawings may be obtained according to these drawings without any creative labor.
Fig. 1 is a kind of structure chart of the button cell of high leakproofness provided by the embodiment of the utility model；
Fig. 2 is the enlarged drawing in the portion A in Fig. 1；
Fig. 3 is the sealed structure chart of existing button cell.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
The embodiments of the present invention provide a kind of button cell of high leakproofness.
Fig. 1 and Fig. 2 are please referred to, the utility model provides a kind of button cell of high leakproofness, including battery core 1, is coated on
Shell 21 outside battery core 1, the shell 21 are coated on the inner casing 8 at battery core 1 top and side, be coated on 1 bottom of battery core and
The place of joining of the shell 7 of 8 side of inner casing, the shell 7 and inner casing 8 is provided with sealing ring 3, the bottom tool of 8 side wall of inner casing
There is flaring 2 outwardly, the flaring 2 squeezes sealing ring 3 and forms o-ring groove 10, and the sealing ring 3 includes being located at 7 He of shell
The sealing ring body 9 at 8 place of joining of inner casing and it is installed in bending part 6 of 9 bottom end of sealing ring body towards inner bending, the inner casing 8
The bottom of side wall be installed in the top surface of bending part 6.
So that the contact between inner casing 8 and shell 7 and sealing ring 3 is even closer, realization simultaneously adds for the setting of the flaring 2
Gu the leakproofness of battery.
In the present embodiment, the width a that the flaring 2 is expanded outwardly is 0.03mm, and the height b of the flaring 2 is 2mm.When
So, in other embodiments, the width a that the flaring 2 is expanded outwardly may be the arbitrary value between 0.01mm-0.5mm, institute
The height b for stating flaring 2 may be arbitrary value among 0.1mm-3mm, and the flaring 2 in above range value may make inner casing
Contact between 8 and shell 7 and sealing ring 3 is even closer, realizes and reinforce the effect of the leakproofness of battery.
In the present embodiment, the material of the shell 21 is iron, certainly, in other embodiments, the material of the shell 21
Other metals can also be selected.
Above-described embodiment is the preferable embodiment of the utility model, but the embodiments of the present invention is not by above-mentioned
The limitation of embodiment, it is made under other any spiritual essence and principles without departing from the utility model to change, modify, replacing
In generation, simplifies combination, should be equivalent substitute mode, is included within the protection scope of the utility model.
