The utility model omits small metal bowls or auxiliary cushion sheets in the inner part of a traditional alkali battery, and the effective volume of the inner part is increased, causing the filling quantity of active substance to be increased, so the utility model has the advantages of improvement of the capability of the alkali dry cell, extension of service life, and improvement of the security and the reliability of the cell during use.
Description
Technical field
The utility model relates to a kind of chemical power source, is a kind of alkaline dry battery.
Background technology
Alkaline dry battery is always as remote controller, portable stereo cassette player power supply.In recent years, along with popularizing of camera, increase rapidly as the demand of camera flashlamp with power supply.The research that how to improve battery capacity is the problem of pendulum in face of the battery industry scientific research personnel.The wall thickness of attenuate metal shell and the thickness of diaphragm paper are the important measures that improve battery capacity.The sealing ring that uses in the alkaline battery, a kind of is to be material with the polypropylene, uses the little bowl of brass to strengthen sealing, another kind of is material with nylon, strengthens sealing with auxiliary metallic gasket.These two kinds of structures all need to use auxiliary spacer or seal little bowl, so all need take the useful space of inside battery, are unfavorable for further improving the capacity of battery.Along with the development of battery technology, battery performance to be had higher requirement, the battery of above-mentioned two kinds of structures can not adapt to user's needs.
Summary of the invention
The purpose of this utility model is to provide a kind of alkaline dry battery of function admirable for battery industry at above-mentioned the deficiencies in the prior art and defective.The shape of this technical scheme employing change inside battery sealing ring is saved auxiliary spacer or the little bowl of metal in traditional alkaline battery, increases the inside battery effective volume, and the loading of increase active material is realized.The centre of this alkaline dry battery is provided with the negative pole of being made up of negative active core-shell material, extexine around negative pole is provided with the anode ring that is shaped with positive active material, between negative pole and anode ring, be provided with diaphragm paper, the fastener of metal current collector inserts in the negative pole, the negative pole bottom of the bottom of fastener and collector body is fixed, the negative pole bottom is provided with sealing ring, the lug boss of sealing ring and the driving fit of fastener perisporium, its bottom support of the peripheral part of sealing ring is in the negative pole bottom, its perisporium engages with the inner peripheral surface of housing, the connecting portion of sealing ring fuses lug boss and peripheral part, the root of connecting portion is recessed to form the explosion-proof ditch of a circle thinner thickness downwards, the periphery of connecting portion is upwards heaved, and forms a circle air guide circle; Between sealing ring lug boss above the explosion-proof ditch and connecting portion, reinforcement is set; At the explosion-proof ditch back side, be provided with discontinuous bracing ring from the connecting portion root to peripheral part, the air guide port that forms between each section bracing ring extends to the air guide circle always, and is connected with the air guide circle.The utility model compared with prior art, auxiliary spacer or the little bowl of metal established in traditional alkaline dry battery have been omitted, sealing ring total height in the battery is lower, increased the inside battery effective volume like this, thereby increased the loading of active material, improved battery capacity and increased the service life, adopted simultaneously and set up reinforcement and bracing ring, the intensity and the reliable air guide channel of sealing ring be can guarantee, fail safe and reliability that battery uses improved.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the ring structure figure in the utility model.
Embodiment
As shown in Figure 1, this alkaline dry battery is in the centre of metal cylindrical shell 1, be provided with the negative pole of forming by negative electrode active material 5, extexine around negative pole 5 is provided with the anode ring 3 that is shaped with positive active material, be provided with diaphragm paper 4 between negative pole and anode ring, the inner peripheral surface of housing scribbles equadag coating film 2.The fastener 6 of metal current collector inserts in the negative pole, and the negative pole bottom 8 of the bottom of fastener and collector body is fixing, and the negative pole bottom of collector body is provided with sealing ring 7.
As shown in Figure 2, the sealing ring 7 in the battery is by lug boss 9, and the connecting portion 11 of peripheral part 15 and connection bump portion and peripheral part is formed.Lug boss 9 and the 6 perisporium driving fits of metal current collector fastener, the bottom support of peripheral part is on the negative pole bottom 8 of collector body, and its perisporium contacts with the housing inner peripheral surface.The internal concave at root of connecting portion 11 forms the explosion-proof ditch 16 of a circle thinner thickness, and its thickness can be between 0.13～0.27mm.The periphery of connecting portion is upwards heaved and is formed a circle air guide circle 12, and the height of heaving the position can be between 0.6～1.5mm.The total height of sealing circle can≤5.5mm.Lug boss and the explosion-proof ditch between the connecting portion at sealing ring are provided with 3～6 reinforcements 10, and the controllable thickness of reinforcement is between 0.3～1.2mm.At the back side of explosion-proof ditch, to heaving the position discontinuous bracing ring 13 is set from the connecting portion root, form 2～7 air guide ports 14 between each section bracing ring, and extend to air guide circle 12 always, be connected with the air guide circle.
When battery because of reasons such as short circuit high temperature heating or overdischarge in voltage rise when high, air guide port in the sealing ring and air guide circle can absorb a part of pressure of connecting portion, prevent from pressure is concentrated on explosion-proof ditch.When inner pressure of battery further rises, the distortion of sealing ring connecting portion, explosion-proof ditch is torn to discharge in the part and is pressed, and can prevent that the sealing ring connecting portion from breaking when taking place, and the battery content disperses or sends the blast sound because of breaking, and improves fail safe and reliability that battery uses.
