Abstract
The utility model discloses a steel shell for preventing a primary lithium battery from swelling. The shape of the steel shell is a cylinder of which one end is open; the bottom of the steel shell is sunken inward to form a concave groove; the depth of the concave groove is 0.4 to 0.6 mm. According to the steel shell for preventing the primary lithium battery from swelling, the problem that the size of the primary lithium battery exceeds a standard after being swelled is solved, so that the deformation degree of the primary lithium battery is reduced.
Description
Technical field
The utility model belongs to disposable lithium-battery technical field, is specifically related to a kind of box hat that prevents disposable lithium-battery bulging.
Background technology
At present, known disposable lithium-battery, due to its superior large electric current, high power and good property at high and low temperature, is more and more subject to vast producer and client's welcome.But after lithium battery work, interior pressure increases, and battery bulging, causes size to exceed standard.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of box hat that prevents disposable lithium-battery bulging, and it can improve after disposable lithium-battery bulging the size problem that exceeds standard, thereby reduces the degree of disposable lithium-battery deformation.
The utility model solves the technical scheme that its technical problem adopts: the box hat that prevents disposable lithium-battery bulging, the cylindrical shape that is shaped as an end opening of described box hat, the bottom of described box hat caves inward and forms a Baltimore groove, and the degree of depth of described Baltimore groove is 0.4～0.6mm.
By technique scheme, the thickness of described box hat is 0.5mm.
By technique scheme, the thickness that described box hat is positioned at Baltimore groove place is 0.25mm.
By technique scheme, the degree of depth of described Baltimore groove is 0.5mm.
The utility model, there is following beneficial effect: by Baltimore groove of box hat bottom design, by reserved space, even if battery bulging in battery use procedure, once whole concave surface is stressed, can bulge, but because concave surface size itself is lower than box hat bottom surface, once bloat, the part that bulging is outstanding is concordant with box hat bottom periphery, and the whole size of battery still can not exceed requirement.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of the utility model embodiment.
Wherein, 1-box hat, 2-Baltimore groove.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
In preferred embodiment of the present utility model, as shown in Figure 1, prevent the box hat of disposable lithium-battery bulging, the cylindrical shape that is shaped as an end opening of box hat 1, its thickness is 0.5mm, the bottom of box hat 1 caves inward and forms a Baltimore groove 2, the degree of depth of Baltimore groove 2 is 0.4～0.6mm, in general, the best results when degree of depth of Baltimore groove is 0.5mm, the thickness that box hat 1 is positioned at Baltimore groove place is 0.25mm.Manufacturing process of the present utility model is simple, uses mould bruising moulding on the battery steel shell that only need produce in routine.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection range of the utility model claims.
