The utility model discloses it is rational in infrastructure, the easily production, adopt the utility model discloses connect electric core and busbar, when the electrical core module short circuit, the connection piece fuse area is fused, and the connection of electric core and busbar is broken off to avoid the heavy current to last the impact to electric core, improve the passive safety protection performance of electric core.
Description
Technical field
This utility model belongs to new energy car battery technical field, and in particular to a kind of battery core connection sheet.
Background technology
When 18650 battery core modules are short-circuited, under high current constant impingement, it will make 18650 battery cores fail, when serious
Even security incident can be caused.There is presently no the counter-measure for the short circuit of 18650 battery core modules.
Utility model content
The purpose of this utility model is to provide one kind can avoid high current from continuing battery core when the short circuit of 18650 battery core modules
The battery core connection sheet of impact.
To reach above-mentioned purpose, this utility model is adopted the following technical scheme that：
A kind of battery core connection sheet, including recombination region, fuse area and Welding Area, fuse area be located at recombination region and Welding Area it
Between；Recombination region is used for connecting bus-bar, and Welding Area is used for connecting battery core electrode；Fuse area offers one or more through holes.
Fuse area opens up through hole, reduces the sectional area of fuse area, so, when the high current that battery core module short circuit is produced is led to
When crossing connection sheet, fuse area produces high temperature and is blown because current carrying area is less, so as to disconnect the connection between battery core and bus-bar.
To avoid spot welding exception, the elongated slot of closed at both ends, elongated slot insertion fuse area and Welding Area are opened up in connection sheet.This
Sample, current loop can be formed during spot welding in Welding Area, strengthen electric current current-carrying ability to bear during spot welding, so as to effectively evade a little
The spot welding exception such as connection sheet fusing, rosin joint, fried weldering during weldering.
Further, elongated slot is located at the centre of fuse area and Welding Area.
Further, battery core connection sheet is plate shaped, i.e., recombination region, fuse area and Welding Area are in same level.
Further, battery core connection sheet is that stairstepping, i.e. fuse area are respectively formed angle with recombination region, Welding Area.
Further, through hole insertion fuse area.
Compared to the prior art, this utility model has the advantage that and beneficial effect：
（1）It is rational in infrastructure, it is easy to produce.
（2）When battery core module short circuit, connection sheet fuse area is blown, and the connection of battery core and bus-bar disconnects, so as to can
Avoid battery core from failing, improve the passive security barrier propterty of battery core.
（3）When carrying out spot welding, can effectively evade the spot welding exceptions such as rosin joint, fried weldering, connection sheet fusing.

Specific embodiment
For ease of understanding this utility model, this utility model is described comprehensively below with reference to accompanying drawings.Accompanying drawing is given
Preferred embodiment of the present utility model.But, this utility model can be realized in many different forms, however it is not limited to this
Embodiment described by text.On the contrary, the purpose for providing these embodiments is to make the understanding to disclosure of the present utility model
It is more thorough comprehensive.
It should be noted that when element is referred to as " being fixed on " another element, it can directly on another element
Or can also there is element placed in the middle.When an element is considered as " connection " another element, it can be directly connected to
To another element or may be simultaneously present centering elements.
Unless otherwise defined, all of technology used herein and scientific terminology with belong to this utility model technical field
The implication that is generally understood that of technical staff it is identical.It is intended merely in term used in the description of the present utility model herein
The purpose of description specific embodiment, it is not intended that in restriction this utility model.Term as used herein " and/or " include one
The arbitrary and all of combination of individual or multiple related Listed Items.
See Fig. 1, connection sheet 10 is for connection to the connector of battery core 20 and bus-bar 30.Fig. 2 is the concrete knot of connection sheet
Structure, connection sheet 10 includes recombination region 101, fuse area 102 and Welding Area 103, and fuse area 102 is located at recombination region 101 and Welding Area
Between 103.Recombination region 101 is connected with bus-bar 30, and specially the upper surface of recombination region 101 is combined with bus-bar 30, combination process
Can be butt-joint or Laser Welding.Welding Area 103 is connected with the electrode of battery core 20, specifically can connect Welding Area 103 by spot welding mode
With the electrode of battery core 20.Connection sheet 10 can be plate shaped or stairstepping, if plate shaped, then recombination region 101, the and of fuse area 102
Welding Area 103 is in same level；If stairstepping, then fuse area 102 is respectively formed folder with recombination region 101, Welding Area 103
Angle.
Fuse area 102 offers one or more through holes 104, so as to reduce the sectional area of fuse area 102.When battery core mould
When the high current that block short circuit is produced passes through connection sheet 10, fuse area 102 produces high temperature and is blown because current carrying area is less, so as to disconnected
The connection between battery core 20 and bus-bar 30 is opened, can so battery core 20 be avoided by high current constant impingement.This specific embodiment
In, the insertion fuse area 102 of through hole 104.
To avoid spot welding exception, the elongated slot 105 of closed at both ends is opened up in connection sheet 10, the described insertion of elongated slot 105 is melted
Disconnected area 102 and Welding Area 103 and positioned at the centre of fuse area 102 and Welding Area 103.Due to the closed at both ends of elongated slot 105, during spot welding
Current loop can be formed in Welding Area 103, so as to increase electric current current-carrying ability to bear during spot welding, so can effectively be evaded a little
The problem of connection sheet easily fusing during weldering.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more concrete and detailed,
But therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that common for this area
For technical staff, without departing from the concept of the premise utility, some deformations and improvement can also be made, these all belong to
In protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be defined by claims.
