Abstract
This utility model discloses a kind of lithium battery pole ear, including lug body, the lug body is constituted in the middle part of the lug by lug head, lug afterbody and between the lug head and the lug afterbody, in the middle part of the lug, one end is connected with the lug head, the other end is connected with the lug afterbody, include some bonding jumpers in the middle part of the lug, the overall width of some bonding jumpers is less than the width of the lug head or lug afterbody.The lithium battery pole ear that this utility model is provided, when outside batteries occur that short circuit current is excessive or in the case that charging current is excessive, the lug body can fuse as electric fuse, disconnect the contact between battery plus-negative plate, so as to ensure battery will not catching fire, or even blast.
Description
Technical field
This utility model is related to technical field of lithium batteries, more particularly to a kind of lithium battery pole ear.
Background technology
With the development of technology, the capacity of present battery be made it is increasing, also, with filling the maturation of technology soon,
The charging current of battery requirements is also increasing.And, existing cell positive pole ear be all on it is similarly hereinafter wide, if in outside batteries
It is short-circuited or in the case that external charger is excessive to battery charge, lug is not susceptible to fusing, it is impossible to play guarantor
The effect of shield battery.
Therefore, prior art existing defects, need to improve.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of lithium battery pole ear.
The technical solution of the utility model is as follows：This utility model provides a kind of lithium battery pole ear, including lug body, institute
State in lug of the lug body by lug head, lug afterbody and between the lug head and the lug afterbody
Portion constitutes, and in the middle part of the lug, one end is connected with the lug head, and the other end is connected with the lug afterbody, in the lug
Portion includes some bonding jumpers, and the overall width of some bonding jumpers is less than the width of the lug head or lug afterbody.
The thickness of the bonding jumper is equal to the thickness of the lug head or lug afterbody.
The width of each bonding jumper is the 5%-45% of the lug body width.
Include 3 bonding jumpers in the middle part of the lug.
The overall width of 3 bonding jumpers is equal to the 75% of the lug body width.
The lug body is made up of aluminum.
The lug body is positive pole ear.
Using such scheme, lithium battery pole ear of the present utility model, when outside batteries occur short circuit current it is excessive or charge
In the case that electric current is excessive, the lug body can fuse as electric fuse, disconnect the contact between battery plus-negative plate, from
And ensure battery will not catching fire, or even blast.
Description of the drawings
Structural representations of the Fig. 1 for this utility model lithium battery pole ear.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
Refer to Fig. 1, this utility model provides a kind of lithium battery pole ear, including lug body 2, the lug body 2 by
Lug head 22, lug afterbody 24, and the lug between the lug head 22 and the lug afterbody 24 in the middle part of 26
Composition, in the middle part of the lug, 26 one end are connected with the lug head 22, and the other end is connected with the lug afterbody 24, the pole
In the middle part of ear, 26 include some bonding jumpers 28, and the overall width of some bonding jumpers 28 is less than the lug head 22 or lug afterbody 24
Width.The thickness of the bonding jumper 28 is equal to the thickness of the lug head 22 or lug afterbody 24.
The width of each bonding jumper 28 is the 5%-45% of 2 width of lug body.In the present embodiment, the pole
In the middle part of ear, 26 include that the overall width of 3 bonding jumpers, 28,3 bonding jumpers 28 is equal to the 75% of 2 width of lug body.
The lug body 2 is made up of aluminum, and the lug body 2 is positive pole ear.
When outside batteries occur that short circuit current is excessive or in the case that external charge current is excessive, the lug body 2 can
Fuse as electric fuse, disconnect the contact between battery plus-negative plate, so as to ensure battery will not catching fire, it is or even quick-fried
It is fried.
As the positive pole ear material of battery battery core is aluminum, and the fusing point of aluminum is relatively low, in the lug that this utility model is provided,
In the middle part of lug, 26 are constituted using a plurality of bonding jumper 28, and the overall width of bonding jumper 28 is less than the width of lug body 2, so as to change
Sectional area of the whole lug by electric current, limits the handling capacity of electric current, and filling for external short circuit or battery occurs in battery
When electric current is excessive, the lug body 2 can produce high temperature, can will be lug body 2 narrow where fuse.Meanwhile, battery is normal
During work, the electric current that lug body 2 also has passes through, and the temperature of lug body 2 can also raised, and is to ensure normal battery operation
When electric current by and lug body 2 temperature is raised when ability to bear, should not will be the 2 sectional area cutting of lug body narrow,
Arrange with specific reference to practical situation.
Preferred embodiment of the present utility model is these are only, this utility model is not limited to, it is all in this practicality
Any modification, equivalent and improvement for being made within new spirit and principle etc., should be included in guarantor of the present utility model
Within the scope of shield.
