Abstract
The utility model discloses a battery outer shell, in particular to a battery outer shell formed by the stretching and pressing of the cold rolling stainless steel strip, which consists of a cylindrical shell body, wherein a cylinder bottom is arranged at one end of the cylindrical shell body and the other end is in an opening shape and the inner diameter at each longitudinal point is equal. The structural feature of the utility model is that the outer diameter of the segment at one end of the mouth part of the cylindrical shell body is larger than that of the other segments. The battery outer shell is applied so as to prevent the mouth part from cracking and damaging when sealing the mouth and avoid the disastrous consequences from occurring such as liquid leakage and explosion, etc. The utility model is especially applied to the small scale high volume battery such as the nickel hydrogen battery, the nickel cadmium battery and the lithium battery.
Description
Technical field
The utility model relates to a kind of shell of compact battery.Be with the battery case of cold-rolling stainless steel steel band specifically by stretching, being stamped to form.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 interior circular diameter of its vertical each point equates.That section outside diameter of its design feature formula cylinder shell oral area one end is greater than the outside diameter of other section.Wherein, that section outside diameter of cylinder shell oral area one end is than the big 0.05mm of outside diameter of other section.
Take such scheme, have the following advantages:
Because that section outside diameter of its cylinder shell oral area one end of battery case of the present utility model is greater than the outside diameter of other section, oral area intensity is higher, make not to be 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 interior circular diameter of its vertical each point equates.And that section outside diameter of close cylinder shell 1 oral area one end is greater than the outside diameter of other section, in the present embodiment, the body wall thickness N of cylinder shell 1 is 0.13mm, the wall thickness M that its oral area is one section is 0.18mm then, makes the outside diameter big 0.05mm of that section outside diameter of cylinder shell 1 oral area one end than 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. 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 interior circular diameter of its vertical each point equates; It is characterized in that the outside diameter of that section outside diameter of cylinder shell (1) oral area one end greater than other section.
2. battery container according to claim 1 is characterized in that the outside diameter big 0.05mm of that section outside diameter of cylinder shell (1) oral area one end than other section.
