The utility model discloses a button cell's negative -electrode cover, bend in the middle part in negative -electrode cover, has strengthened negative -electrode cover's intensity, is favorable to the perpendicular knot edge sealing mouth and the radial extrusion of existing equipment to seal, guarantees battery seal's technical indicators such as sealing performance, negative -electrode cover does not have a turn -ups, reduces turn -ups material and the shared thickness of material, and the capacity of battery has been improved in the built -in space that has increased the battery.
Description
Technical field
This utility model is related to cell art, more particularly to a kind of button cell.
Background technology
The key technical indexes capacity more and more higher of modern batteries, the discharge capacity improved by same model battery increase
The interior empty volume of the profile shell and lid molectron of battery, accordingly increases electrical chip, and a kind of mode side for improving battery capacity
Method.When button cell is assembled at present, the flange first by plastic ring with negative cover is needed to be assembled together, it is then logical with positive cover again
Excess pressure equipment press-fit realizes sealing.As negative cover has flange, in the case where model is set, flange can take interior
Empty volume, wastes inner space;The assembling consuming time of plastic ring and negative cover is long simultaneously, for this purpose, research changes the lid of battery
Structure there is positive meaning.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, this utility model provides a kind of button cell, and which has structure letter
Single, built-in volume is big, handling ease, it is easy to the features such as assembling.
This utility model solve technical scheme that its technical problem adopted for:
A kind of button cell, including negative cover and anode cover, also including the plastics being arranged between negative cover and anode cover
Circle, is provided with bending part in the middle part of the wall of the negative cover side, the diameter of the negative cover epimere side wall is little compared with the diameter of hypomere side wall, institute
State plastic ring and offer the cannelure being engaged with negative cover hypomere side wall and bending part, the plastic ring is included positioned at cannelure
The inner collar of inner side and the external toroidal ring in outside, the external toroidal ring upper end sets the buckling parts coordinated with anode cover flange.
As the improvement of above-mentioned technical proposal, the epimere side wall of the negative cover, hypomere side wall and bending part rounding off.
Used as the improvement of above-mentioned technical proposal, the epimere side wall inner surfaces of the negative cover are kept with the inner surface of inner collar
Concordantly.
Used as the improvement of above-mentioned technical proposal, the external toroidal ring upper end is higher than bending part.
The beneficial effects of the utility model have:
A kind of button cell of the present utility model, the bending in the middle part of the negative cover, enhances the intensity of negative cover, is conducive to existing
There is the vertical button edge sealing and transverse shear stress sealing of equipment, it is ensured that the technical specification such as sealing property of battery seal, negative pole drowning
There is flange, reduce flange material and thickness shared by material, increase the built-in space of battery, improve the capacity of battery.
Description of the drawings
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail, wherein:
Fig. 1 is the semi-section schematic diagram of this utility model embodiment;
Fig. 2 is the sectional view of this utility model embodiment plastic ring.
Specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of button cell, including negative cover 1 and anode cover 2, also including being arranged on 1 He of negative cover
Plastic ring 3 between anode cover 2, is provided with bending part 4, the diameter of 1 epimere side wall of the negative cover in the middle part of 1 side wall of the negative cover
Little compared with the diameter of hypomere side wall, this feature is conducive to the vertical button edge sealing of existing equipment and transverse shear stress sealing, it is ensured that battery
The technical specifications such as the sealing property of sealing, while the intensity of increased by 1 side wall of negative cover;1 no flange of the negative cover, relatively
In the negative cover 1 of traditional flange, the operation of the manufacture of novel negative electrode cap 1 is reduced, and the plasticity requirements of raw material steel are reduced, while
In the case of model identical, the capacity using the battery of novel negative electrode cap 1 is bigger;31 upper end of the external toroidal ring is higher than bending part
4, so can ensure that anode cover 2 seals the sealing for fastening with negative cover 1, prevent the leakage of button cell, while being easy to note
Glue-feeder is cut off during modeling plastic ring.
With further reference to Fig. 2, also offer including the plastic ring 3 and be engaged with 1 hypomere side wall of negative cover and bending part 4
Cannelure 32, cannelure 32 fitted with the lower end of negative cover;The plastic ring 3 includes the internal ring on the inside of cannelure 32
Circle 33 and the external toroidal ring 31 in outside, the epimere side wall inner surfaces of the negative cover 1 are concordant with the holding of the inner surface of inner collar 33, this
Sample has to be easy to inner stuffing is carried out to battery, and inside battery volume is bigger;31 upper end of the external toroidal ring sets and anode cover 2
The buckling parts 34 that flange coordinates, its effect are to prevent positive cover 2 when with 3 seal buckle edge sealing of negative cover, and plastic ring 3 is squeezed
Pressure is overflowed, and protection negative cover 1 is indeformable, it is ensured that its internal capacity.Plastic ring 3 is moulded in negative cover 1 using injection-moulding device
One-time formed, which is integrated with negative cover 1, and plastic ring 3 also can curve U-shaped plastic ring using plastic sheeting, with sealing
Glue bond is made, better;3 underlayer thickness of the plastic ring in 0.5mm or so, two side thickness of cannelure is 0.15 ~
0.2mm, while sealing is ensured, relative to traditional injection plastic ring, 3 inside and outside wall of plastic ring on novel negative electrode cap 1
It is thinner, so can effectively increase the built-in space of Novel button, improve cell volume, while saving used by manufacture plastic ring 3
Material.
The above, simply better embodiment of the present utility model, but this utility model is not limited to above-mentioned reality
Example is applied, as long as which reaches technique effect of the present utility model with any same or similar means, should all belong to of the present utility model
Protection domain.
