Embodiment Construction

[0021] Such as figure 1 As shown, the button battery provided by the embodiment of the present invention includes a first pole shell 3, a second pole shell 2, an insulating sealing ring 4, an annular bracket 5, a first current collector strip 6, a second current collector strip 7, and a fuse 8 and cell 9.

[0022] The first pole shell 3, the second pole shell 2 and the insulating sealing ring 4 form a button battery accommodating cavity 10 through precise combination. Generally speaking, the first pole shell 3 is a positive pole shell, and the second pole shell 3 The pole shell 2 is a negative pole shell, and of course the opposite also exists, and both pole shells are made of 304 stainless steel and formed by stamping. In one embodiment, both the first pole shell 3 and the second pole shell 2 are made of steel with a thickness of 0.2 mm to form a relatively stable structure.

[0023] The first pole case 3 includes a bottom plate 31 and a side wall 32 extending upward from t...

Abstract

The invention relates to a button cell. The button cell comprises a first pole shell, a second pole shell, an insulating seal ring and a cell, wherein an accommodating is formed by the first pole shell, the second pole shell and the insulating seal ring together; the cell is arranged inside the accommodating cavity; the second pole shell comprises a body and a flanging formed by bending and extending the periphery of the body downwards; the insulating seal ring comprises a main body part and an inward bending part formed by extending the main body part inwards, the main body part is clamped between the flanging of the second pole shell and the first pole shell, the inward bending part is positioned below the flanging, and the end face of the inward bending part does not exceed the inner side face of the flanging of the second pole shell. The invention also relates to a button shell. The structure of the insulating seal ring is improved without occupying the inner space of the second pole shell, the stability of the inner structure of the button cell is further strengthened while the capacity is improved, and the sealing property of the insulating seal ring is improved.

Description

technical field [0001] The invention relates to the field of electronic products, in particular to a button casing and a button battery using the button casing. Background technique [0002] The button battery visibly includes the positive and negative stainless steel shells and the materials that play an insulating and sealing role between them. The combination and sealing of the three materials are usually achieved by crimping and sealing processes well known in the button battery industry. Inside the battery, the positive and negative electrodes of the specific configuration of the cell are connected to the positive and negative stainless steel casings in a specific electrical and mechanical contact. The cell is made by winding the positive and negative electrodes and the separator, or the positive and negative electrodes and the separator are made of laminated sheets, and the cells packaged in the battery are soaked or infiltrated by the electrolyte. [0003] The positi...
