Abstract
The utility model relates to a connecting structure of the electrode post of the super capacitor and the electrode handle which are welded together. The conflux row connected by the electrode post and the electrode handle is piled by the melting metal. The utility model is a connecting structure for the electrode post and the electrode handle of the super capacitor which has a small contacting resistance and is steady and reliable with high work efficiency.
Description
Technical field
The utility model discloses the syndeton between a kind of ultracapacitor pole and the lug, belongs to the ultracapacitor technical field.
Background technology
Ultracapacitor is a kind of novel energy-storing device, has good high-power charge-discharge performance, energy conversion efficiency height, good temp characteristic, recycles advantages such as life-span length and environmental protection.
A lot of electric equipments all need ultracapacitor that very big power is provided, and the high-power characteristic of ultracapacitor seems particularly important.If the internal resistance of ultracapacitor is big, not only can reduce its high-power characteristic, and cause and the heat that produces also can accumulate quickly by internal resistance, make ultracapacitor quicken to worsen, reduce useful life.And the welding between ultracapacitor pole and the lug is exactly one of key factor that influences its internal resistance.
Fastening or the electric resistance welding of employing screw that connected mode between general ultracapacitor pole and the lug has, the contact resistance after the connection is bigger; Though what have adopts some than advanced welding manners, but the material of pole and lug generally all adopts nickel, iron, steel or copper, and the bus-bar that often needs to add in addition between pole and lug is assisted welding, because these melting point metals are all very high, so when the welding of carrying out between pole and the lug, can produce very big heat, heat passes on the electrode slice along lug, might make the softening closed pore of barrier film of ultracapacitor, influences the performance of entire product.
Summary of the invention
The purpose of this utility model has provided a kind of contact resistance is little, reliable and stable and operating efficiency the is high ultracapacitor pole and new Joining Structure of lug of welding.
The utility model is achieved in that the syndeton of a kind of ultracapacitor pole and lug, it is characterized in that: be welded to connect.Described pole material is any one in lead, lead alloy, the aluminum or aluminum alloy.Described lug material is any one in lead, lead alloy, the aluminum or aluminum alloy.Describedly be welded as in acetylene welding, ratio-frequency welding, supersonic welding, Laser Welding or the arc welding any one.
Because pole and lug material have adopted the lower metal of fusing point, when being welded to connect, a part of metal on pole and the lug or the metal molten that adds in addition, the liquid metals of fusing is along the groove trickling and the filling of weld jig, naturally form the bus-bar between pole and lug after the cooled and solidified, thereby pole and lug are welded together.
The utility model is a kind of contact resistance is little, reliable and stable and operating efficiency the is high ultracapacitor pole and new Joining Structure of lug of welding.
Description of drawings
Fig. 1 is the front elevational schematic before wherein a kind of mode of the utility model is welded;
Fig. 2 is that overlooking before wherein a kind of mode of the utility model is welded looked schematic diagram.
Embodiment
The utility model is described in further detail below in conjunction with embodiment.
Embodiment 1
Pole and lug material all adopt lead-calcium alloy.With reference to the accompanying drawings 1, at first lug 2 beam splitting are positioned in the slot corresponding in the weld jig, then pole 1 also is installed on the position of weld jig correspondence.Adopt acetylene welding to carry out welding between pole and the lug then.During welding, make the metal molten of pole lower end, and make of the groove trickling of the liquid metals of fusing, until filling smooth and reaching certain thickness along weld jig.Pull down weld jig after metal cools is solidified and finish welding.
Pole and lug material all adopt terne metal.With reference to the accompanying drawings 2, at first lug 2 beam splitting are positioned in the slot corresponding in the weld jig, then pole 1 also is installed on the position of weld jig correspondence.In the groove of weld jig, add an amount of terne metal piece, adopt acetylene welding to weld then.During welding, make and add an amount of terne metal piece fusing, and make of the groove trickling of the liquid metals of fusing, until filling smooth and reaching certain thickness along weld jig.Pull down weld jig after metal cools is solidified and finish welding.
