Abstract
The utility model discloses a battery shell, particularly to a battery shell made of cold rolling stainless steel belt being stretched and pressed, which comprises a cylinder shaped shell body, wherein one end of the cylinder shaped shell body is provided with a cylinder bottom, the other end is of exposure shape, portrait point outer circle diameter of which is the same. The utility model is characterized in that one end of the cylinder shaped shell body mouth is smaller in diameter than the other part inner circle diameter. With the battery shell, phenomenon of sealing mouth being crashed or damaged is prevented and serious consequence of battery liquid leakage or explosion is eliminated. The utility model is especially suitable for small type high capacitance battery such as NI-MH battery, NiCd battery and lithium battery.
Description
Technical field
The utility model relates to a kind of shell of compact battery.Be the battery case of making by stretching, punching press with the cold-rolling stainless steel steel band specifically.Be particularly useful on the miniaturized high capacity battery of ni-mh, NI-G and lithium battery and so on.
Background technology
Know all that in the battery production industry its capacity of miniaturized high capacity battery of ni-mh, NI-G and lithium battery and so on and the thickness of its shell are closely bound up, under same size, the thin more capacity of the thickness of battery case is big more.Therefore, at present the shell of this class battery all do very thin, and the interior circular diameter and the outside diameter of its vertical each point all equate.Because this battery case is thinner, and the interior circular diameter of its vertical each point is equal respectively with outside diameter, makes very easily to occur oral area cracking, damage situations when sealing, even can directly cause serious consequences such as battery leakage, blast.
The utility model content
The utility model will solve to such an extent that problem provides a kind of battery case.Use this battery case, oral area cracking, damage situations are avoided the generation of serious consequences such as battery leakage, blast in the time of can preventing to seal.
For addressing the above problem, take following technical scheme:
Battery case of the present utility model comprises cylinder shell, and at the bottom of an end of cylinder shell had tin, the other end was uncovered shape, and the outside diameter of its vertical each point equates.Circular diameter is less than the interior circular diameter of other section in that section of its design feature formula cylinder shell oral area one end.Wherein, in that section of cylinder shell oral area one end circular diameter than the little 0.05mm of interior circular diameter of other section.
Take such scheme, have the following advantages:
Because circular diameter is less than the interior circular diameter of other section in that section of its cylinder shell oral area one end of battery case of the present utility model, make that oral area thickness is thick, intensity is high, be not prone to oral area cracking, damage situations when sealing, thereby avoided the generation of serious consequences such as battery leakage, blast.
Description of drawings
Fig. 1 is a battery case structural representation of the present utility model;
Fig. 2 is the I point enlarged diagram among Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, battery case of the present utility model contains cylinder shell 1, and at the bottom of an end of cylinder shell 1 is processed with tin 2, the other end is processed into uncovered shape, and the outside diameter of its vertical each point equates.And near the interior circular diameter of circular diameter in that section of cylinder shell 1 oral area one end less than other section.In the present embodiment, the body wall thickness N of tubular shell 1 is 0.13mm, and the wall thickness M that its oral area is a section is 0.18mm then, makes in that section of cylinder shell 1 oral area one end circular diameter than the little 0.05mm of interior circular diameter of other section.Oral area cracking, damage situations occur thereby guaranteed to seal Shi Buhui, avoided the generation of serious consequences such as battery leakage, blast.
Claims (2)
1. a battery case comprises cylinder shell (1), and at the bottom of an end of cylinder shell (1) has tin (2), the other end is uncovered shape, and the outside diameter of its vertical each point equates; It is characterized in that circular diameter is less than the interior circular diameter of other section in that section of cylinder shell (1) oral area one end.
2. battery case according to claim 1 is characterized in that circular diameter is than the little 0.05mm of interior circular diameter of other section in that section of cylinder shell (1) oral area one end.
