Abstract
The utility model provides a battery, a serial communication port, including positive polar cap, utmost point ear, positive polar cap includes that the face that bottom and lid were located on the bottom covers, the bottom has the upper surface that is close to the face lid and keeps away from the lower surface of face lid, the bottom is kneaded dough through solder joint fixed connection between the lid, the solder joint is located the lower surface of bottom, the face is covered and is equipped with the exhaust hole, utmost point ear one end is welded in the lower surface of bottom, be equipped with the through -hole on the utmost point ear, follow in the exhaust hole expose in the through -hole, through -hole and exhaust hole are coincident completely. The bottom is kneaded dough and is equipped with explosion -proof ball between the lid. The utility model discloses the beneficial effect who realizes is: a battery, connects the bottom and kneads dough the solder joint of lid and be located the lower surface of bottom, like this when battery encapsulate, the solder joint encapsulation inside the battery, avoid the solder joint to expose in the air, easy rusty shortcoming, air vent that the face was covered, messenger battery has good exhausting function, explosion -proof ball has increased battery's security performance.
Description
Technical field
This utility model relates to a kind of battery technology, is specifically related to a kind of battery.
Background technology
The positive electrode cap of the battery of commercial type is generally adopted upper cover and lower cover and seals structure, is usually upper cover and is welded on down and covers, and solder joint is positioned at and covers, and in use, owing to solder joint exposes in atmosphere, easily gets rusty.
At present, the lug of battery covers the steam vent of positive electrode cap, so can block steam vent, causes that the gas produced in battery can not smooth and easy be discharged, thus affecting the security performance of battery.
Utility model content
The deficiencies in the prior art that aim to solve the problem that of the present utility model, and the one provided has antirust, explosion-proof, degassing function is good simultaneously battery.
This utility model adopts techniques below to be attained in that a kind of battery, it is characterized in that, including positive electrode cap, lug, described positive electrode cap includes bottom and the cover being covered on bottom, described bottom has the upper surface of close cover and away from the lower surface of cover, connect by solder joint is fixing between described bottom and cover, described solder joint is positioned at the lower surface of bottom, described cover is provided with steam vent, described lug one end is welded in the lower surface of bottom, described lug is provided with through hole, described steam vent exposes in described through hole, described through hole and steam vent are completely superposed.
It is provided with explosion-proof ball between described bottom and cover.
This utility model realizes providing the benefit that: a kind of battery, the solder joint connecting bottom and cover is positioned at the lower surface of bottom, so when cell package, solder joint is encapsulated in inside battery, it is to avoid solder joint exposes in atmosphere, the shortcoming easily got rusty, passage on cover, making battery have good degassing function, increase battery, explosion-proof ball adds the security performance of battery.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of battery；
Wherein, 1-cover, 2-bottom, 3-steam vent, 4-lug, 5-through hole.
