Abstract
The utility model provides a kind of ni-mh cylindrical battery box hat, box hat is untight cylindrical shape, comprise box hat bottom surface, box hat stage casing and box hat top, box hat bottom surface, box hat stage casing and box hat top integral, box hat bottom surface is provided with boss, boss is arranged at outside box hat, the wall thickness on box hat top is greater than the wall thickness in box hat stage casing, the wall thickness in box hat stage casing is 0.15 ± 0.02mm, the wall thickness on box hat top is 0.2 ± 0.02mm, when the ni-mh cylindrical battery box hat that the utility model provides avoids winding there is distortion in box hat top, occur during jet-bedding that box hat splits groove, finally occur splitting neck phenomenon when electrolyte sealing annotated by battery, and capacity increases about 10%, seal compression resistance simultaneously and increase about 30%, scheme of the present utility model improves the quality of production of Ni-MH battery, reduce the percent defective of product.
Description
Technical field
The utility model belongs to cell art, is specifically related to a kind of ni-mh cylindrical battery box hat.
Background technology
Existing market ni-mh column type conventional low capacity battery steel shell (AA type, AAA type) external diameter is 13.9mm, thickness is 0.20mm, height is that 50mm is in order to increase inside battery space, thus raising battery capacity, what high-capacity battery adopted substantially is thickness is 0.15mm, be highly 50mm, external diameter is the box hat of 14.2, box hat inner space about increases by 5% ~ 6%, battery capacity can improve about 10% simultaneously, but thickness be 0.15mm box hat due to too thin after winding complete pole group enters shell faucal yielding, because box hat is partially thin during jet-bedding, also be easy to cause box hat to split groove, easily occur when Ni-MH battery seals splitting neck phenomenon simultaneously, box hat oral area thickness is on the low side can be caused sealing pressure on the low side about 30% simultaneously, when cell internal pressure is bigger than normal, block is easily rushed out, battery electrolyte is easily caused to leak, cause and scrap, reduce Ni-MH battery overall quality.
Utility model content
The purpose of this utility model is to provide a kind of ni-mh cylindrical battery box hat, and solve in existing high-capacity battery technology yielding after box hat winding, during sealing, pressure reduces about 30%, and the technical problem that sealing easily occurs splitting neck and causes battery electrolyte to leak.
The technical scheme that the utility model adopts is, a kind of ni-mh cylindrical battery box hat, box hat is untight cylindrical shape, comprise box hat bottom surface, box hat stage casing and box hat top, box hat bottom surface, box hat stage casing and box hat top are integral, box hat bottom surface is provided with boss, and boss is arranged at outside box hat, and the wall thickness on box hat top is greater than the wall thickness in box hat stage casing.
Feature of the present utility model is also:
The wall thickness in box hat stage casing is 0.15 ± 0.02mm, and the wall thickness on box hat top is 0.2 ± 0.02mm;
Box hat top length is 5.5 ± 0.1mm;
Box hat top inner side is provided with chamfering, and the size of chamfering is R0.1;
The height of box hat bottom surface boss is 0.3 ± 0.02mm.
The beneficial effects of the utility model are: the utility model provides a kind of ni-mh cylindrical battery box hat, by the top wall thickness dimension of Ni-MH battery box hat being greater than the wall thickness dimension in box hat stage casing, not only increase Ni-MH battery inner space 5% ~ 6%, and avoid the appearance distortion in box hat top when reeling of Ni-MH battery box hat, simultaneously when the follow-up jet-bedding of battery because box hat wall is partially thin, box hat is caused to split groove, and sealing pressure about 30% can be increased after box hat oral area increases thickness, avoid occurring splitting neck when electrolyte sealing annotated by battery, battery electrolyte is finally caused to leak, battery becomes the phenomenon of waste product.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of ni-mh cylindrical battery of the utility model box hat;
Fig. 2 is the plan structure schematic diagram of a kind of ni-mh cylindrical battery of Fig. 1 the utility model box hat.
In figure, 1. box hat bottom surface, 2. box hat stage casing, 3. box hat top.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model provides a kind of ni-mh cylindrical battery box hat, as shown in Figure 1 and Figure 2, Ni-MH battery box hat is untight cylindrical shape, comprise box hat bottom surface 1, box hat stage casing 2 and box hat top 3, box hat bottom surface 1, box hat stage casing 2 and box hat top 3 are integral, box hat bottom surface 1 is provided with boss, and boss is arranged at outside box hat, and the wall thickness on box hat top 3 is greater than the wall thickness in described box hat stage casing 2.
The wall thickness in the box hat stage casing 2 of ni-mh cylindrical battery box hat of the present utility model is 0.15 ± 0.02mm, the wall thickness on box hat top 3 is 0.2 ± 0.02mm, box hat top 3 length is 5.5 ± 0.1mm, also chamfering is provided with inside box hat top 3, the size of chamfering is R0.1, the height of box hat bottom surface 1 boss is 0.3 ± 0.02mm, what the utility model adopted increases 0.05 ± 0.02mm by box hat top wall thickness, when avoiding winding there is distortion in box hat top, occur during jet-bedding that box hat splits groove, finally occur splitting neck phenomenon when electrolyte sealing annotated by battery, battery electrolyte is finally caused to leak, battery becomes the phenomenon of waste product, simultaneously when box hat top wall thickness increases, not only increase inner space 5% ~ 6%, and do not change Ni-MH battery internal structure, and the addition of battery electrolyte inside, thus do not affect the capacitance of Ni-MH battery, and capacity can increase about 10%, seal compression resistance simultaneously and increase about 30%.
A kind of ni-mh cylindrical battery box hat that the utility model provides is increased by the wall thickness on Ni-MH battery box hat top, if whole for Ni-MH battery box hat thickness is increased, so just reduce box hat inner space, simultaneously electrolyte content of annotating will reduce, the capacitance of Ni-MH battery also can reduce thereupon, the Ni-MH battery amount of capacity of same like this model can be affected, so ni-mh cylindrical battery box hat of the present utility model not only avoid the damage that Ni-MH battery box hat quality in the fabrication process causes, add battery capacity simultaneously.
