Abstract
The utility model relates to an electronic components technical field is a nickel -clad copper changes tin utmost point ear who is used for ultracapacitor system particularly, including nickel plating copper -base ear, tin area and nickel plating copper strips, nickel plating copper -base ear contains one end and the welding of electric core that utmost point ear was glued, and the other end is equipped with first weld part, is equipped with the second weld part on the tin area, and first weld part and second weld part adopt that the nickel plating copper strips is fixed to be pasted tightly, and nickel plating copper strips adoption ultrasonic bonding is with first weld part and second weld part linking together tightly. The utility model discloses well structural design is equitable, tightly binds round tip and tin tip outside nickel plating copper -base ear with the nickel -clad copper strengthening band, the disposable undamaged copper of having realized changes tin, has improved the resistant folding endurance that copper changes tin, reduces the damage and the loss of buckling many times and bringing at the in -service use in -process, has reduced production processes, has saved manufacturing cost greatly, for the processing operation in later stage facilitating, does not make resistance increase when having strengthened utmost point ear intensity, is favorable to the application in reality greatly.
Description
[technical field]
The utility model relates to technical field of electronic components, and a kind of nickel-clad copper for ultracapacitor turns tin lug specifically.
[background technology]
Ultracapacitor is a kind of novel energy-storing device with quick charge, high-specific-power, long-life, relatively high-energy-density, and there is important application in the fields such as electronic product, new-energy automobile, novel energy (solar energy, wind energy etc.)/intelligent grid energy storage that are included in.Ultracapacitor is divided into Hard Roll ultracapacitor and Soft Roll ultracapacitor according to the difference of housing material.
Soft Roll ultracapacitor uses copper polar ear as negative lug usually, and aluminium pole ears is as positive pole ear.Lug mainly play in ultracapacitor conduction current and with the effect such as external circuit is connected, improve its folding resistance, workability and conductivity very important.Current most of ultracapacitor, in the fabrication process in order to improve applied environment, broaden application field, usually adopting positive pole aluminium-to-nickel technology, comprising riveted joint, ultrasonic bond, Laser Welding etc., then according to the actual requirements, then carry out turning tin or other metal solder.This operating process increases operation and the cost of production undoubtedly, reduces production efficiency.
[utility model content]
The utility model makes complicated, that useful life is shorter technical problem for lug in existing Soft Roll ultracapacitor, provides a kind of and be easy to operate, folding resistance is good, is convenient to process, the nickel-clad copper of good conductivity turns tin lug.
To achieve these goals, design a kind of nickel-clad copper and turn tin lug, comprise nickel-clad copper lug, tin band and nickel plating copper strips, nickel-clad copper lug contains one end and the battery core welding of tab, the other end is provided with the first weld part, tin band is provided with the second weld part, and the first weld part and the second weld part adopt nickel plating copper strips fixedly to be adjacent to, and nickel plating copper strips employing ultra-sonic welded is by the first weld part and the second weld part linking together tightly.
The first described weld part is connected with nickel plating copper strips with on the second weld part.
Described nickel-clad copper lug and tin band are all strip structure.
Compared with the existing technology, its advantage is the utility model:
It is reasonable in design that copper in the utility model turns nickel extreme ear structure, tightly bind round in nickel-clad copper lug outer end and tin end with nickel-clad copper reinforcing band, the disposable intact copper that achieves turns tin, improve the folding resistance that copper turns tin, reduce and repeatedly bend the damage and loss that bring in actual use, decrease production process, greatly save production cost, the process operation that can be the later stage provides convenient, does not make resistance increase, be greatly conducive to application in practice while enhancing lug intensity.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model;
In figure: 1. nickel-clad copper lug 2. tin band 3. nickel plating copper strips.
[embodiment]
Below in conjunction with accompanying drawing, the utility model is described in further detail, and this structure and principle are very clearly concerning the people of this specialty.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model nickel-clad copper turns tin lug, wherein nickel-clad copper lug and tin band are all strip structure, and contain one end and the battery core welding of tab at nickel-clad copper lug, the other end and tin band are respectively arranged with the first weld part and second weld part of welding.First weld part and the second weld part apply one deck tab.
When welding, the first above-mentioned weld part and the second weld part nickel plating copper strips are fixedly adjacent to.Adopt ultra-sonic welded at two the part nickel plating copper strips be connected to each other, by Part I and Part II linking together tightly, then connect into an overall lug and turn over, then by opposite side tightly banding.This mode enhances the intensity of lug, does not also increase internal resistance, is greatly conducive to application in practice.
In addition, this mode is not only applicable to Soft Roll ultracapacitor lug, be also applicable to lithium ion cell polar ear etc., and the copper being applicable to other occasions turns tin.Meanwhile, this method is not only applicable to nickel-clad copper and turns tin, and can also be used as nickel-plated aluminum and turn tin, copper turns nickel, aluminium-to-nickel etc.The thickness of lug can adjust in 0.1-0.5mm and width 2-10mm, and the weld width of nickel plating copper strips also can make the appropriate adjustments, and can either meet Structural Design Requirement, can reach welding requirements again, can make to make lug in this way.
Claims (3)
1. a nickel-clad copper turns tin lug, comprise nickel-clad copper lug, tin band and nickel plating copper strips, it is characterized in that nickel-clad copper lug contains one end and the battery core welding of tab, the other end is provided with the first weld part, tin band is provided with the second weld part, first weld part and the second weld part adopt nickel plating copper strips fixedly to be adjacent to, and nickel plating copper strips employing ultra-sonic welded is by the first weld part and the second weld part linking together tightly.
