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 supply of these electronic products also develops 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 is 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 be because of the factor such as battery charger failure and undue charging with inside battery chemical reaction
Abnormal gas are produced, cause cell internal pressure excessive, so as to occur battery explosion accident.Protected however, existing battery anti-explosion is fried
Protection unit is present under poor reliability, pressure-resistant scope, complicated, the weak point such as processing request height.
The content of the invention
Technical problem：In order to solve the defect of prior art, the invention provides the lithium battery top that a kind of band overcharges function
Cover plate.
Technical scheme：A kind of band that the present invention is provided overcharges the lithium battery top cap plate of function, including is moulded on substrate, negative pole
Material, plastics, negative pole sealing ring, positive pole sealing ring, negative pole pole plate, positive pole pole under plastics, positive pole under plastics, negative pole on positive pole
Post；The negative pole pole plate is provided with negative pole pole and SSD；Under the negative pole plastics 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 fixed with SSD, SSD hole, SSD on the SSD seats successively from bottom to top close
Seal, porous plate, SSD pasters；The explosionproof hole bottom is provided with burst disk, and paster is protected in top provided with explosion-proof valve.
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, the SSD is copper SSD.
Beneficial effect：Lithium battery top cap plate that the present invention is provided is simple in construction, with low cost, easy to use, substantially reduce
Manufacturing cost and use cost.
The present invention uses copper SSD, SSD to be welded on negative pole pole plate, passes through O-ring seal between SSD and substrate
Sealing.The cover plate, can be sensitiveer during reversion when inside battery produces gas, while identical current carrying area, is conventional cover plate
2-3 times.The battery because overcharge aerogenesis and caused by potential safety hazard when, more can effectively ensure overall electricity than conventional SSD structures
The safety in pond.
