Pond does not have water-proof function in itself, when moisture immerses battery main body part, can avoid PCM protection circuit plates, cause battery
Both positive and negative polarity direct short-circuit, battery are likely to result on fire or blast when super-large current discharges, and threaten the personal safety of consumer.
Traditional Waterproof battery is outside battery main body to cover one layer of plastic casing again by injection or ultrasonic bonding mostly,
Play a part of to seal waterproof.As production technology is more complicated, there is tiny gap or when pin hole is not enclosed, naked eyes are very
It is difficult to observe, cause to seal waterproof failure.The other thickness for being exactly plastic casing is than anti-water power that is larger, being made using the technique
Pond, energy density substantially can reduce, and be unfavorable for extending the use time of electronic product.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of waterproof lithium battery, simple production process, and
The effect of sealing waterproof can be reached.
To solve above-mentioned technical problem, the technical solution of the utility model is：A kind of waterproof lithium battery, the battery
Main body, the waterproof case being wrapped in outside battery main body and external unit, the battery main body are connected with PCM protection circuit plates, institute
State external cell surface and be provided with PP glue-lines, the inner surface of the waterproof case is provided with CPP glue-lines, and one end of the waterproof case sets
Stretched in waterproof case by outlet and be connected with PCM protection circuit plates in the one end for having outlet, the external unit；It is described
It is sealed by heat at the outlet of waterproof case.Amalgamation after being heated with CPP glue-lines using PP glue-lines, enables waterproof case
It is enough to seal, and then make battery main body and PCM protection circuit plates in waterproof case that there is water-proof function.
Used as improvement, the waterproof case is aluminum mold.Suitable pit can be stamped out according to the size of battery main body,
Battery main body is placed in pit, and the surrounding of aluminum plastic film is carried out heat-seal, plays a part of to seal waterproof, this plastic-aluminum membrane structure
Waterproof case, as thickness is than relatively thin, the energy density of integral battery door can be obviously improved.
Used as improvement, the battery main body is aluminum-shell battery, box hat battery or polymer soft-package battery.
As improvement, accommodating cavity in the waterproof case, is formed, house the shape of cavity and the shape phase of battery main body
Seemingly.
Used as improvement, being shaped as the battery main body is square, cylindrical or arc.
As improvement, the Surface coating insulation high-temperature-resistant adhesive tape of the battery main body, battery main body part and waterproof are prevented
Shell produces electronic conduction.
Used as improvement, the thickness of the PP glue-lines is 50 ~ 110um.
Used as improvement, the external unit is lead, lug, FFC soft arranging wires or FPC soft boards.
The beneficial effect brought compared with prior art by this utility model is：
Battery main body and PCM protection circuit plates are encapsulated in inside the waterproof case of sealing, even if waterproof case immersion,
PCM protection circuits plate still shielding, it is to avoid the super-large current that acute short circuit is produced is to battery itself and electronic equipment
The destruction of generation；Using aluminum plastic film as waterproof case, it is easy to encapsulation operation, the energy that can be obviously improved battery again is close
Degree.
Description of the drawings
Fig. 1 is this utility model structural representation.
Fig. 2 is the schematic diagram that battery main body is connected with external unit.
Specific embodiment
