Background technique
Existing battery module is generally series-parallel by positive and negative polarity wire by two to multiple battery cells or battery device
It constitutes, single battery monomer is connect by positive and negative polarity wire with external cell monomer or battery device, and existing attachment device is
The rectangle nickel strap of positive and negative polarity wire terminal connection is connected by way of spot welding with battery cell positive and negative anodes.The rectangle nickel strap width
Generally 4mm, length is generally 16mm, and anode pole is generally circular in cross section, and diameter is generally 3mm, therefore nickel strap spot welding
Range there was only diameter≤3mm circle；For battery cathode, the range of nickel strap spot welding generally also only has diameter 3mm's
Region.The both ends of one nickel strap respectively connect a positive wire or respectively a piece cathode conductor of connection, therefore connect same nickel strap
Two positive wires or the terminals of two cathode conductors be separated by the length of a nickel strap, i.e. 16mm causes connection to be played pendulum；
And Wire termination is separated by a distance also longer with battery cell positive and negative anodes, and stretching resistance is caused to reduce, and battery cell positive and negative anodes hold
Easily fall off with positive and negative polarity wire.
Utility model content
Technical problem to be solved by the utility model is to provide a kind of battery cell and conducting wires suitable for battery module
Attachment device, the positive and negative anodes junction of positive and negative polarity wire terminal and battery cell use, to fix well positive and negative
The connection of polar conductor terminal and battery cell positive and negative anodes can enhance stretching resistance, avoid waving or fall off.
In order to solve the above technical problems, the utility model discloses a kind of battery cell positive and negative anodes suitable for battery module
It is arranged on battery cell with the attachment device of conducting wire including several battery cells connected by positive wire with cathode conductor
There is a battery cell Anode and battery monomer cathode, the terminal of the positive wire and cathode conductor is 5mm each by a diameter
Round nickel sheet be connected to battery cell Anode and battery monomer cathode.
Further, the edge of the round nickel sheet is provided with the connection end of outwardly convex, the positive wire and negative
The terminal of polar conductor is fixed by the connection end and round nickel sheet.
Further, the edge of the round nickel sheet is provided with a connection end.
Or, there are two connection ends for the edge setting of the circle nickel sheet.
Further, described two connection ends are located at the same diameter institute of round nickel sheet on straight line.
The circle that general battery plus-negative plate spot welding size area is 2~3mm of diameter, battery cell Positive Poles are generally straight
The circle of diameter 3mm uses diameter for the round nickel sheet of 5mm, had both been bonded Positive Poles and spot welding region, also there is enough distances
Positive wire or cathode conductor are connected, it is respectively separated by a distance to substantially reduce positive and negative electrode Wire termination, reduces from 16mm
To 5mm, stretching resistance is greatly enhanced, it is too long and play pendulum to also avoid nickel strap, and the setting of connection end, then facilitates circle
Shape nickel sheet and conducting wire are connected and fixed.
