Existing double electric layer capacitor structure as shown in Figure 1, the diaphragm paper of insulating properties be placed on double layer electrodes and centre, wherein double layer electrodes is used conductive adhesive to be attached on the upper cover part formed with stainless steel, and another double layer electrodes is used conductive adhesive to be attached on the lower cover part formed with stainless steel.Nonaqueous electrolyte is charged into double layer electrodes and reaches in insulating properties diaphragm paper space.Upper cover part and lower cover partly adopt insulating properties rubber sealing insulation, and two terminals directly are welded on the outer surface of above-mentioned double electric layer capacitor upper and lower covers, form this capacitor both positive and negative polarity fishplate bar.
In prior art, generally adopt single terminal directly to be welded on above-mentioned double electric layer capacitor, as shown in Figure 2, the upper terminal of plane is through laser welding on upper cover part, and the cut-off type lower terminal is attached on the lower cover part with laser welding.This mode complex procedures, precision is poor, and efficiency is low.
Corrective measure terminal as shown in Figure 4 further, its is whole the manufacture during fabrication, is about to several terminals and the whole manufacture of cutting portion, between terminal, be arranged in parallel, is provided with pin hole on cutting portion.Terminal is when welding on capacitor; at first after after the terminal translation being implemented to cut off, recycling cylinder or CAM critically up are transferred to double layer capacitor, weld; this design causes the equipment complexity; the equipment precision requirement is high, and operating speed sharply descends, and manufacturing expense is high; moreover; for easy welding, usually also need on terminal, plate gold, silver or tin, more XXL the manufacturing cost of terminal.
The utility model content
The purpose of this utility model just is to overcome the defect of above-mentioned prior art, provide a kind of utilize that simple bonding machine just can be easy by terminal soldering on double electric layer capacitor, reduce manufacturing expense, accelerate operating speed, the terminal of the button double electric layer capacitor of increasing work efficiency.
For realizing that the technical scheme that above-mentioned utility model purpose is taked is:
A kind of terminal of button double electric layer capacitor, by into a single integrated structure cutting portion and several positive terminals and negative terminal, formed, positive terminal and negative terminal are set in parallel on cutting portion, and the coupling part of positive terminal, negative terminal and cutting portion has the first line of cut and the second line of cut;
The first cut-out line is contrary with the cut direction of the second cut-out line;
Evenly be provided with pin hole on cutting portion, this pin hole is arranged according to the equidistant of 4-8mm;
Gold-plated head on positive terminal and negative terminal is coated with gold or silver or tin coating;
Positive terminal and negative terminal laser welding, at button double electric layer capacitor both sides external face, form double electric layer capacitor positive terminal and negative terminal.
The utility model, by the connecting portion at terminal and cutting part, opening line of cut, makes each terminal early in the hemisect state, when needs carry out the terminal separation, only need to just can realize according to 90 degree are crooked, thereby remove the setting of cutting machine in technique; Simultaneously, arranging according to precision and minimum interference of pin hole spacing designs, and after cutting like this, through complicated handover program, the seat of terminal not there will be deviation yet, can accurate being welded on correct position.
The simple bonding machine of the utility model utilization just can be easy by terminal soldering on double electric layer capacitor, there is welding position accurate, manufacturing expense is low, operating speed is fast, the advantages such as operating efficiency height.
