Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing embodiment.
The bottom inside face of sealing ring 4 of traditional alkaline button cell is rectangular, as shown in Figure 1.When positive pole cake 5 is not longitudinal
During expansion, come as shown in figure 4, barrier film 6 now is not jacked up.During the use of battery, due to the hair of cell reaction
It is raw, laterally fettered by box hat, positive pole cake 5 can violent longitudinal dilatation, the positive expansion of positive pole cake 5 drive barrier film 6 move up (every
Film jacked up come), as shown in fig. 7, now the right angle of sealing ring 4 made of plastics can be formed at barrier film 6 shearing force with
Barrier film 6 is punctured, barrier film 6 punctures the both positive and negative polarity contact of rear battery so as to can cause the short circuit of battery.
Embodiment one：
Alkaline button cell 1 disclosed by the invention, including positive pole cup 2, negative pole top 3, sealing ring 4, calamine cream, positive pole cake 5, every
Film 6 and electrolyte, separated between positive pole cake 2 and lithium metal by barrier film 6, pass through sealing ring 4 between positive pole cup 2 and negative pole top 3
Insulation, electrolyte are filled in the cavity that negative pole top 3 is formed with positive pole cup 2.As shown in Fig. 2 sealing ring 4 includes plastics system
Into annular body, annular body includes vertical ring part 41 and transverse annular portion 42, and transverse annular portion 42 is positioned at vertical annular
The inside bottom position in portion 41, the flexible annular that the medial extremity integrated injection molding in transverse annular portion 42 has thickness to taper into are prevented
Shield portion 421, the lower surface and the lower surface of flexible annular protection department 421 in transverse annular portion 42 seamlessly transit.
As shown in Fig. 2 the initiating terminal thickness of flexible annular protection department 421 and the medial extremity thickness phase in transverse annular portion 42
When flexible annular protection department 421 is in the structure inwardly tilted.As shown in figure 5, when the also not positive expansion of positive pole cake 5, will not drive
Dynamic barrier film 6 moves up, and does not produce stronger active force between sealing ring 4 and barrier film 6 now mutually also.As shown in figure 8,
During using alkaline button cell 1, positive pole cake 5 expands upwards, drives barrier film 6 to move up, and produces strong effect between the two
Power；And the sealing ring 4 of the alkaline button cell 1 of the present invention is provided with flexible annular protection department 421, therefore, when positive pole cake 5 is positive
When expansion drives the barrier film 6 to move up, sealing ring 4 will not puncture barrier film 6, avoid the generation of button cell short circuit phenomenon.
Embodiment two：
Other parts are identical with embodiment one, and difference is：As shown in figure 3, the starting of flexible annular protection department 421
1/3-1/2 of the rear end for the medial extremity rear end in transverse annular portion 42 is held, as shown in figure 9, under 6 upward active force of barrier film, it is flexible
The end at annular shield end 421 is in the structure inwardly tilted.
As shown in fig. 6, when the positive expansion of positive pole cake 5, do not drive barrier film 6 to move up, sealing ring 4 now with every
Have no very strong interaction force between film 6, and flexible annular protection department 421 is not when by the active force of barrier film, flexible annular
The lower surface of protection department 421 is in a plane with the lower surface in transverse annular portion 42.As shown in figure 9, using alkalescence button
During formula battery 1, positive pole cake 5 expands upwards, drives barrier film 6 to move up, and produces strong active force between the two；It is and of the invention
The sealing ring 4 of alkaline button cell 1 be provided with flexible annular protection department 421, therefore, when the positive expansion of positive pole cake 5 drive every
When film 6 moves up, because the end at flexible annular protection end 421 is in the structure inwardly tilted, therefore sealing ring 4 will not puncture
Barrier film 6, avoid the generation of button cell short circuit phenomenon.
