Description
Technical field
The utility model relates to a kind of battery and connects, and more particularly, it relates to a kind of cell connector.
Background technology
The developing rapidly of auto industry has promoted the progress of industry such as global machinery, the energy and the development of the aspect such as economy, traffic, also greatly facilitate the life of people simultaneously, New Generation of Electric Vehicle can the new traffic tool of variation configuration as pollution-free, the energy, causes the common concern of people in recent years and obtains great development.Electric automobile is compared with general-utility car, and core technology is battery technology, the battery pack of electric automobile by dozens of even up to a hundred single batteries formed by series, parallel mode, to meet the driving requirement of electric automobile.Series, parallel between single battery in current battery group adopts full copper sheet or full nickel sheet to connect, but full copper sheet connect make it with battery battery core not prison welding admittedly, thus resistance is increased.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide that a kind of resistance is little, the cell connector of sheet metal stable connection.
For achieving the above object, the utility model provides following technical scheme: a kind of cell connector, comprise negative straps and positive strap, described positive strap is all identical with the shape size structure of negative straps, described negative straps and positive strap are formed by some sheet metals, the one side of described sheet metal is provided with some boss, the another side of described sheet metal is provided with groove at the correspondence position of boss, described some sheet metals are connected together by supersonic welding, and described boss is embedded in groove.
The utility model is set to further: the sheet metal of described positive strap is aluminium flake, and described aluminium flake is set to five, and the thickness of described aluminium flake is 0.1mm.
The utility model is set to further: described five aluminium flakes are by the thickness 0.4mm after ultrasonic bonding.
The utility model is set to further: the sheet metal of described negative straps is copper sheet, and described copper sheet is set to four, and the thickness of described copper sheet is 0.1mm.
The utility model is set to further: described four copper sheets are 0.35mm by the thickness after ultrasonic bonding.
The utility model is set to further: the cell wall of described groove is provided with the annular groove arranged around groove circumference, described boss is provided with the bulge loop with annular groove adaptation, described bulge loop is embedded in annular groove.
Compared with prior art, the utility model has the advantage of: by the mode of ultrasonic bonding, the thickness after five aluminium flake welding is made to be 0.4mm, the thickness after four copper sheet welding is made to be 0.35mm, make between every sheet aluminium flake, fit together all closely between copper sheet, and be embedded in groove by boss, be embedded in the annular groove in groove by the bulge loop on boss again, boss is connected more firm with groove, thus make to be positioned together firmly between sheet metal, even if bend, also dislocation and gap can not be produced, thus make positive strap, the resistance decreasing of negative straps, even if in use also can not gap be produced.

Embodiment
Referring to figs. 1 through Fig. 4, the utility model cell connector embodiment is described further.
A kind of cell connector, comprise negative straps 2 and positive strap 1, described positive strap 1 is all identical with the shape size structure of negative straps 2, it is characterized in that: described negative straps 2 and positive strap 1 are formed by some sheet metals, the one side of described sheet metal is provided with some boss 3, the another side of described sheet metal is provided with groove 4 at the correspondence position of boss 3, and described some sheet metals are connected together by supersonic welding, and described boss 3 is embedded in groove 4.
The sheet metal of described positive strap 1 is aluminium flake 11, and described aluminium flake 11 is set to five, and the thickness of described aluminium flake 11 is 0.1mm.
Described five aluminium flakes 11 are by the thickness 0.4mm after ultrasonic bonding.
The sheet metal of described negative straps 2 is copper sheet 12, and described copper sheet 12 is set to four, and the thickness of described copper sheet 12 is 0.1mm.
Described four copper sheets 12 are 0.35mm by the thickness after ultrasonic bonding.
The cell wall of described groove 4 is provided with the annular groove 41 arranged around groove 4 circumference, described boss 3 is provided with the bulge loop 31 with annular groove 41 adaptation, described bulge loop 31 is embedded in annular groove 41.
By the mode of ultrasonic bonding, thickness after five aluminium flakes 11 are welded is 0.4mm, thickness after four copper sheets 12 are welded is 0.35mm, make between every sheet aluminium flake 11, fit together all closely between copper sheet 12, and be embedded in groove 4 by boss 3, be embedded in the annular groove 41 in groove 4 by the bulge loop 31 on boss 3 again, boss 3 is connected more firm with groove 4, make to be positioned together firmly between sheet metal, even if bend, also dislocation and gap can not be produced, thus make positive strap 1, the resistance decreasing of negative straps 2, even if in use also can not gap be produced.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
