Description
Technical field
This utility model relates to poly-lithium battery technical field, the negative lug of a kind of combinative structure and battery.
Background technology
Lithium battery is a kind of large-capacity high-power battery, is mainly used on mini-plant.Poly-lithium battery is a point both positive and negative polarity, and lug is exactly the metallic conductor extracted by both positive and negative polarity from battery core, and the popular ear saying battery positive and negative polarities is the contact point when carrying out discharge and recharge, and negative electrode lug uses nickel (Ni) material, therefore is also called nickel lug.
Its solderability of nickel strap after the existing nickel strap for nickel lug, in order to ensure corrosion resistance, needs to process its surface, and surface processes can be substantially reduced, it is not easy to upper stannum.Therefore the solderability of nickel lug and anticorrosive property cannot be taken into account simultaneously.In view of this, prior art has yet to be improved and developed.
Utility model content
In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide negative lug and the battery of a kind of combinative structure, it is intended to the solderability and the anticorrosive property that solve nickel strap in prior art are the problems that cannot simultaneously take into account.
The technical solution of the utility model is as follows:
A kind of negative lug of combinative structure, wherein, including: the first nickel strap, the second nickel strap, upper tab and lower tab；Described first nickel strap and the second nickel strap are respectively arranged with that the first weld part and the second weld part, described first weld part and the second weld part are stacked to be welded and fixed；Described upper and lower tab covers described stacked weld.
Preferably, the negative lug of described combinative structure, wherein, the length of described second nickel strap is between 7.0mm to 8.5mm.
Preferably, the negative lug of described combinative structure, wherein, described first weld part and the second weld part are stacked the length of weld between 2.00mm to 3.00mm.
Preferably, the negative lug of described combinative structure, wherein, described upper and lower tab covers the length of the second nickel strap between 1.00mm to 2.00mm.
A kind of battery, wherein, including above-mentioned negative lug, described negative lug is connected with electrode.
Beneficial effect: the negative lug of combinative structure described in the utility model and battery, wherein, the negative lug of described combinative structure includes: the first nickel strap, the second nickel strap, upper tab and lower tab；Described first nickel strap and the second nickel strap are respectively arranged with that the first weld part and the second weld part, described first weld part and the second weld part are stacked to be welded and fixed；Described upper and lower tab covers described stacked weld.Design ingenious rationally, protect lug the most well, it is to avoid occur because repeating to bend the phenomenon causing lug to rupture；More importantly take into account anticorrosive property and the solderability of negative lug, thus ensure that delivery quality is high, reduce entreprise cost.

Fig. 1 is the schematic diagram of the negative lug preferred embodiment of combinative structure described in the utility model.
Fig. 2 is the explosive view of the negative lug preferred embodiment of combinative structure described in the utility model.
Detailed description of the invention
This utility model provides negative lug and the battery of a kind of combinative structure, for making the purpose of this utility model, technical scheme and effect clearer, clear and definite, further describes this utility model below.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
Please also refer to the schematic diagram of the negative lug preferred embodiment that Fig. 1 and Fig. 2, Fig. 1 are combinative structure described in the utility model, Fig. 2 is the explosive view of the negative lug preferred embodiment of combinative structure described in the utility model.As it can be seen, the negative lug of described combinative structure includes: first nickel strap the 100, second nickel strap 200, upper tab 300 and lower tab 400；Described first nickel strap 100 and the second nickel strap 200 are respectively arranged with the first weld part 110 and the second weld part 120, and described first weld part 110 and the second weld part 120 are stacked and are welded and fixed；Described upper tab 300 and lower tab 400 cover described stacked weld.
Described first nickel strap 100 is for being connected with electrode, and it is after surface processes, and corrosion resistance is preferable, meets the negative lug demand for corrosion resistance of existing lithium battery.And the second nickel strap 200 solderability is preferable.Therefore by combining the first nickel strap 100 and the second nickel strap 200 so that negative lug can have good corrosion resistance and solderability simultaneously.Specifically, in the present embodiment, the first half of described first nickel strap 100 is provided with the first weld part 110, and the lower half of the second nickel strap 200 is provided with the second weld part 120, by laser-beam welding machine, the first weld part 110 and the second weld part 120 is stacked and is welded and fixed.Then, described stacked weld is covered by upper tab 300 and lower tab 400.
Further, in the present embodiment, in the negative lug of described combinative structure, the length of described second nickel strap is between 7.0mm to 8.5mm.
Further, in the negative lug of described combinative structure, described first weld part and the second weld part are stacked the length of weld between 2.00mm to 3.00mm.Typically arrange three row's solder joints (2 solder joints of first row, 3 solder joints of second row, the 3rd row two solder joint) the 3rd row's solder joint to be covered by upper and lower tab.Preferably, described upper and lower tab covers the length of the second nickel strap between 1.00mm to 2.00mm.
It addition, this utility model additionally provides a kind of battery, it includes that above-mentioned negative lug, described negative lug are connected with electrode.
In sum, the negative lug of combinative structure of the present utility model and battery, design ingenious rationally, protect lug the most well, it is to avoid occur because repeating to bend the phenomenon causing lug to rupture；More importantly take into account anticorrosive property and the solderability of negative lug, thus ensure that delivery quality is high, reduce entreprise cost.
Should be understood that; application of the present utility model is not limited to above-mentioned citing; for those of ordinary skills, can be improved according to the above description or convert, all these modifications and variations all should belong to the protection domain of this utility model claims.
