Abstract
The open a kind of open circuit protection lithium battery pole ear of this utility model, including the first lug, the second lug, the fixing fixing glue connecting two lugs and the sheet metal pack being electrically connected with two lugs；The T-shaped structure of described sheet metal pack, the horizontal end of T-shaped is low bulk sheet metal, and the perpendicular end of T-shaped is highly expanded sheet metal, fixes with the second lug top and be connected bottom highly expanded sheet metal.This utility model lithium battery pole ear is used for the positive and negative lug of lithium battery, its the first lug other end is connected with external circuit, the second lug other end is connected with the positive/negative plate of battery battery core, when high temperature or overcurrent, highly expanded sheet metal has bigger expansion, drive horizontal low bulk sheet metal away from step site, disconnect the electric connection between two lugs, it is to avoid security incident occurs；When temperature or electric current recover normal, sheet metal pack recovers initial condition, two lug connections.
Description
Technical field
This utility model relates to technical field of lithium batteries, particularly relates to a kind of open circuit protection lithium battery pole ear.
Background technology
Lithium battery, because of its technology maturation, use safety and stability, is widely used in the power supply of electronic product.Existing lithium battery pole ear generally uses single unitary construction, in practicality, once there is external short circuit in lithium battery, and electric current increases the heat caused can make the diaphragm failures in battery battery core, cause aseptate two pole pieces direct-connected, cause the dangerous accident of electricity consumption of lithium battery.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of open circuit protection lithium battery pole ear, and under there is overcurrent conditions, lug self open circuit realizes protecting whole circuit.
The technical solution of the utility model is as follows:
A kind of open circuit protection lithium battery pole ear, including the first lug, the second lug, the fixing fixing glue connecting two lugs and the sheet metal pack being electrically connected with two lugs；The T-shaped structure of described sheet metal pack, the horizontal end of T-shaped is low bulk sheet metal, and the perpendicular end of T-shaped is highly expanded sheet metal, fixes with the second lug top and be connected bottom highly expanded sheet metal；Being provided with the chamber of half opening bottom described first lug, be equipped with one step site about described chamber, the step site arcwall being arranged above a center of circle inwardly, the level interval between described two arcwalls is more than the length of low bulk sheet metal.
It is preferred that the chamber of described half opening, two step site, two arcwalls are symmetrical configuration.
It is preferred that described low bulk sheet metal two ends are center of circle semi arch structure inwardly.
Further, described step site height is the 1/2 ~ 2/3 of low bulk sheet metal width.
Use such scheme, this utility model lithium battery pole ear is used for the positive and negative lug of lithium battery, its the first lug other end is connected with external circuit, the second lug other end is connected with the positive/negative plate of battery battery core, when high temperature or overcurrent, highly expanded sheet metal has bigger expansion, drives horizontal low bulk sheet metal away from step site, disconnect the electric connection between two lugs, it is to avoid security incident occurs；When temperature or electric current recover normal, sheet metal pack recovers initial condition, two lug connections.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the off state figure that this utility model omits fixing glue.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
Referring to figs. 1 through shown in Fig. 2, this utility model provides a kind of open circuit protection lithium battery pole ear, including first lug the 1, second lug 2, the fixing fixing glue 3 connecting two lugs 1,2 and the sheet metal pack 4 being electrically connected with two lugs；The described T-shaped structure of sheet metal pack 4, the horizontal end of T-shaped is low bulk sheet metal 42, and the perpendicular end of T-shaped is highly expanded sheet metal 41, fixes with the second lug 2 top and be connected bottom highly expanded sheet metal 41；1 chamber 101 being provided with half opening at the bottom of described first lug, is equipped with a step site 101a about described chamber, step site 101a is arranged above center of circle arcwall 101b inwardly, and the level interval between described two arcwall 101b is more than the length of low bulk sheet metal 42.
The step site 101a of chamber 101, two of described half opening, two arcwall 101b are symmetrical configuration.
Described low bulk sheet metal 42 two ends are center of circle semi arch structure inwardly.
The height of described step site 101a is the 1/2 ~ 2/3 of low bulk sheet metal 42 width.
In this utility model, fixing glue 3 is provided with through hole with the contact position of highly expanded sheet metal 41, in order to highly expanded sheet metal 41 expands and contraction because of variations in temperature at above-below direction.
To sum up, this utility model lithium battery pole ear is used for the positive and negative lug of lithium battery, its the first lug 1 other end is connected with external circuit, second lug 2 other end is connected with the positive/negative plate of battery battery core, when high temperature or overcurrent, highly expanded sheet metal 41 has bigger expansion, drives horizontal low bulk sheet metal 42 away from step site 101a, disconnect the electric connection between two lugs 1,2, it is to avoid security incident occurs；When temperature or electric current recover normal, sheet metal pack 4 recovers initial condition, two lug 1,2 connections.
These are only preferred embodiment of the present utility model, be not limited to this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
