Abstract
The utility model relates to a sealed battery, which is provided with a positive metal casing, a negative metal casing matched with the positive metal casing, and a sealing ring integrated with the negative metal casing. A core is arranged between the positive metal casing and the negative metal casing, and the sealing radius R of an edge ring of the positive metal casing ranges from 1mm to 1.4mm. The sealed battery is high in strength and stability.
Description
Technical field
The utility model relates to the battery technology field, especially a kind of intensity height, the sealed battery that stability is strong.
Background technology
The ring banding port radius 0.8mm of the cathode metal housing of traditional button cell, the intensity of sealing the battery after the shaping is on the low side, and stability is also relatively poor, and the operating efficiency of battery sealing machine is also very low.
The utility model content
The technical problems to be solved in the utility model is: in order to solve the problem in the above-mentioned background technology, the utility model provides an intensity height, the sealed battery that stability is strong.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of sealed battery, the negative pole metal shell that has the cathode metal housing and be complementary with it, and with the into a single integrated structure sealing ring of negative pole metal shell, be provided with Chi Xin between cathode metal housing and the negative pole metal shell, the ring banding port radius R of cathode metal housing is 1mm～1.4mm.
The beneficial effects of the utility model: the ring banding port radius R of the cathode metal housing in the sealed battery of the present utility model is 1mm～1.4mm, and the intensity of sealing the battery after the shaping is very high, and stability is also stronger, and the efficient of sealing machine has increased by 2 times.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, the cathode metal housing, 2, the negative pole metal shell, 3, sealing ring, 4, Chi Xin.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of sealed battery as shown in Figure 1, the negative pole metal shell 2 that has cathode metal housing 1 and be complementary with it, and with the into a single integrated structure sealing ring 3 of negative pole metal shell 2, be provided with Chi Xin 4 between cathode metal housing 1 and the negative pole metal shell 2, and pond core 4 is made up of chip, battery powder and conducting film, and the ring banding port radius R of cathode metal housing 1 is 1mm～1.4mm.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
