Being easily caused welding easily to come off when cell connector being welded in battery, and causing whole short circuit, vehicle is running over
Circut breaking and the short-circuit fire phenomenon for thus causing occurs in journey.
The content of the invention
It is an object of the invention to provide a kind of cell connector and its manufacture method with power battery pack, with solution
The problem of the battery modules meeting short circuit proposed in stating background technology, and the diversity between cell connector and welding battery
Problem.
For achieving the above object, the present invention provides following technical scheme：A kind of cell connector and its and power battery pack
Manufacture method, including I shape connection sheet, the I shape connection sheet is mainly by pushing connection sheet, four convex closures and separate gap
Seam composition, the connection sheet that pushes are arranged on four angles of I shape connection sheet, and the shim is arranged on I shape connection
The centre of piece, and shim splits I shape connection sheet for two bonding pads, two connections of the I shape connection sheet are distinguished
Zhi Zuo not there are two convex closures.
Preferably, the length of the I shape connection sheet is 7-13mm.
Preferably, the width of the I shape connection sheet is 7-9mm.
Preferably, the width for separating slot is 0.4-1.2mm.
Preferably, the width for pushing connection sheet is 0.4-1.0mm.
Preferably, the distance between two convex closures of the homonymy are 2.5-3.5mm.
Preferably, the distance between described relative two convex closures are 3.5-4.5mm.
Preferably, the width of the convex closure is 1.0-2.1mm.
Preferably, the height of the convex closure is 0.3-0.7mm.
Preferably, small stair is provided with the convex closure, and the width of small stair is 0.1-0.8mm.
Compared with prior art, the invention has the beneficial effects as follows：Present invention improves in 18650 set of cells every battery it
Between diversity, and the design of I shape, the convex closure in I shape connection sheet can be more easy to contact with battery in welding, and
And on convex closure, having a small stair so that connection sheet more fully can be contacted with battery, increased between battery and connection sheet
The firmness of connection, and the effect of small stair can allow the firmness between connection sheet and battery reach a single point its
Pulling force of the firm welding degree more than 2kg, whole nickel sheet firm welding degree can exceed more than 8KG, and I shape connection sheet can ensure that
Each battery in whole battery modules can ensure to be welded in whole connection sheet, improve the yield of welding, it is ensured that
Will not be because of rosin joint after welding completely so that whole short circuit.
