2）Using manual operation, there are the recessive problems such as quality and safety；
3）Lock screw technique has considerable restraint to the structure of core strueture, keeps the limitation that battery core designs very big, has
Design needs process after increasing several roads that could complete in process of production, not only wastes material and human resources, but also limit product
The diversification of structure；
4）It is not easy to realize and produce in enormous quantities.
In order to solve problem above, it is generated using the mode that probe connects.However it gives birth in the market in the past few years
The high current probe of production all exists use unstable safety problem always, including Japan and the developed countries such as South Korea, all because
The contact portion of probe cannot come into full contact with the lug of battery core and high temperature is caused to burn out probe and lug, when and have on fire show
As.
Currently, in the processing technology of probe, the end face of probe can process very smooth, and the lug of battery core is also opposite
It is more smooth, but two workpiece are all moveable, and always there is certain beat in production, many times this beat
Angle be not to be visible to the physical eyes, so effective contact point can be found after amplification by leading to seem good two parts of contact
Just only several, so that the contact surface resistance of conducting increases, temperature increases, and finally burns out battery core.
