Opening up late many, electrokinetic cell the most just starts to produce in enormous quantities, and at the initial stage produced, the electricity of substantially more than 50A
Core produces, and during chemical conversion with partial volume, the connection between power supply and battery core, is all to be led to by the positive and negative polar curve ear of power supply
Cross that screw is locked to be completed on two lugs of battery core, make to produce, the battery core of batch in efficiency and technique in this way
On all there is the biggest restriction, the principal element producing this restriction is as follows:
1) lock screw needs long time, and directly resulting in human resources wastes in a large number；
2) manual operation is used to there is the recessive problem such as quality and safety；
3) lock screw technique has considerable restraint to the structure of core strueture, and the limitation making battery core design is very big, some designs
After needing in process of production to increase a few road, operation just can complete, and i.e. waste material and human resources, limit again the structure of product
Variation；
4) it is difficult to realize producing in enormous quantities.
In order to solve problem above, the mode using probe to connect produces.But given birth on market in the past few years
The big current probe produced, the most all exists and uses unstable safety problem, the developed country such as including Japan and Korea S, all because of
The contact portion of probe can not be fully contacted with the lug of battery core and be directed at high temperature and burn out probe and lug, time and have on fire showing
As.
At present, in the processing technique of probe, the end face of probe can be processed the most smooth, and the lug of battery core is the most relative
The most smooth, but two workpiece are all moveable, always there is certain beat, many times this beat aborning
Angle be not to be visible to the physical eyes, so causing seeming two good parts of contact can find effective contact point after amplification
The most several, and then the contact surface resistance of conducting is increased, temperature raises, and finally burns out battery core.
