Description
Technical field
The utility model belongs to electrokinetic cell field, and more particularly to a kind of band overcharges the lithium battery top cap plate of function.
Background technology
At present, with increasingly miniaturization, lighting and the Portable belt of electronic product, such as video camera, notebook and hand
Machine etc., the driving power of these electronic products also develop towards high power capacity, high security and the direction of lighting, lithium battery with
The good characteristics such as its high power capacity, are widely used in electronic product.
Lithium battery includes housing, cover plate and battery core etc., and wherein battery core is placed in the inside of housing, and the upper end of housing has upper
End opening, cover plate are then enclosed in the opening of the upper end of housing, then by forming pole on the cover board, then can by lithium battery with
Outside electronic component is electrically connected with, and realizes power supply.
Lithium battery when in use can because of the factor such as battery charger failure and undue charging and with inside battery chemical reaction and
Abnormal gas are produced, cause cell internal pressure excessive, so as to which battery explosion accident occur.Protected however, existing battery anti-explosion is fried
Poor reliability be present in protection unit, under pressure-resistant scope, complicated, the weak point such as processing request height.
Utility model content
Technical problem：In order to solve the defects of prior art, the utility model provides the lithium electricity that a kind of band overcharges function
Pond lamina tecti.
Technical scheme：A kind of band provided by the utility model overcharges the lithium battery top cap plate of function, including on substrate, negative pole

Post；The negative pole pole plate is provided with negative pole pole and SSD seats；Under the negative pole plastics be provided with the second negative pole pole column hole and
SSD holes；Plastics are provided with the second Positive Poles hole under the positive pole；Porous plate, are sequentially provided with the substrate from left to right
One negative pole pole column hole, explosionproof hole, the second negative pole pole column hole；Negative pole sealing ring, the second negative pole are sequentially passed through on the negative pole pole
Pole column hole, the first negative pole pole column hole, plastics on negative pole；Positive pole sealing ring, the second positive pole pole are sequentially passed through in the Positive Poles
Plastics in post holes and the first Positive Poles hole, positive pole；It is close to be fixed with SSD, SSD hole, SSD on the SSD seats successively from bottom to top
Seal, porous plate, SSD pasters；The explosionproof hole bottom is provided with burst disk, and top is provided with explosion-proof valve protection paster.
As an improvement, the first negative pole pole column hole and the second negative pole pole column hole both sides are respectively equipped with a pair of positioning and guidings
Groove；Plastics include half plastics of a pair of fastenings respectively on plastics and positive pole on the negative pole, half plastic bottoms be provided with it is fixed
The lug boss that position guide groove coordinates.
Improved as another kind, the SSD is copper SSD.
Beneficial effect：Lithium battery top cap harden structure provided by the utility model is simple, cost is cheap, easy to use, significantly
Reduce manufacturing cost and use cost.
The utility model uses copper SSD, and SSD is welded on negative pole pole plate, by O-shaped close between SSD and substrate
Seal seals.The cover plate, can be sensitiveer during reversion when inside battery produces gas, while identical current carrying area, is conventional
2-3 times of cover plate.The battery because overcharge aerogenesis and caused by potential safety hazard when, than routine SSD structures more can effectively ensure it is whole
The safety of body battery.
