Abstract
The utility model belongs to the field of cells, and particularly relates to an insulting rubber ring of a button cell. The insulting rubber ring of the button cell comprises an outer side wall and a bottom, wherein the outer side wall is perpendicular to the bottom; the bottom is upwards bent to form an inner side wall; an included angle between the bottom and the inner side wall is a blunt angle; and a groove is formed among the bottom, the inner side wall and the outer side wall. The insulting rubber ring of the button cell is characterized in that the groove comprises an arc-shaped groove and a U-shaped groove; the circle center of the arc-shaped groove is positioned at one side of the inner side wall; the arc-shaped groove comprises an arc-shaped groove bottom and an arc-shaped groove opening; the arc-shaped groove opening is communicated with the outside; the U-shaped groove comprises two U-shaped groove openings; and the U-shaped groove opening, which is close to the inner side wall, of the U-shaped groove is communicated with the arc-shaped groove bottom. The insulting rubber ring of the button cell, which is provided by the utility model, has the advantages of simple structure and good sealing property.
Description
Technical field
The utility model belongs to field of batteries, relates in particular to a kind of battery insulation cushion rubber.
Background technology
Button cell comprises negative pole box hat, positive pole steel shell, barrier film, electrode material, is filled with the insulation cushion rubber between negative pole box hat and the positive pole steel shell.Be separated by by the insulation cushion rubber between the both positive and negative polarity of button cell, the insulation cushion rubber plays insulating effect on the one hand, prevents the generation of short circuit phenomenon, also plays a part on the other hand sealing, prevents electric liquid seepage.Traditional insulation cushion rubber comprises lateral wall, bottom, lateral wall be cylindric and and bottom vertical, the bottom is bent upwards the formation madial wall, and the angle between bottom and the madial wall is the obtuse angle, has formed a groove between madial wall and the lateral wall for the insertion of negative cover sidewall.In the manufacturing process of button cell, to insulate and coat fluid sealant in the cushion rubber, the negative pole box hat is inserted in the insulation cushion rubber, fixation by fluid sealant is fitted the two, because the sidewall of negative pole box hat has a plurality of bending parts, has the space between the sidewall of this insulation cushion rubber and negative pole box hat, can not accomplish real sealing, after button cell was packaged, the electric liquid easily slit between cushion rubber and negative pole box hat the phenomenon of leakage occurred easily toward exosmosis.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of button cell insulation cushion rubber, comprise lateral wall, the bottom, described lateral wall and described bottom vertical, described bottom is bent upwards the formation madial wall, angle between described bottom and the described madial wall is the obtuse angle, described bottom, described madial wall, formed a groove between the described lateral wall, it is characterized in that: described groove comprises a deep-slotted chip breaker and a U-lag, the center of circle of described deep-slotted chip breaker is positioned at described madial wall one side, described deep-slotted chip breaker comprises deep-slotted chip breaker bottom land and deep-slotted chip breaker notch, described deep-slotted chip breaker notch communicates with the external world, described U-lag comprises two U-lag notches, and the close described U-lag notch of described U-lag and described madial wall is communicated with described deep-slotted chip breaker bottom land.
The beneficial effects of the utility model are: the groove that is formed by bottom, madial wall, lateral wall is formed by connecting by a deep-slotted chip breaker and a U-lag, be identical between the groove of insulation cushion rubber and the sidewall of negative pole box hat, reached real sealing state, after button cell is packaged, the phenomenon of leakage can not appear.It is a kind of simple in structure that the utility model provides, the button cell insulation cushion rubber of good seal performance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
