Contact force he is one of the elements in the cold-press terminal blocks, if we do not have enough contact force, even if we again good conductive materials also useless. , for example, if we contact force is very low, then the conductor will have shift between him and conductive piece, this will make the oxidation contaminated, unexpectedly and the contact resistance. So we were using the yueqing the fountain electrical cold-press terminal blocks of time is not affected by the other.

Cold-press terminal he is pressing line box, so very reliability, when we put the screw again his thread tongue is to play up the above, this will have a reaction of a screw. It is also caused by the temperature because it is over, we are not to tighten the screw.

If he pressure on the conductor wire frame is done in 168 hours of homework of aging, so he has to take place in a 20 times the gravity of vibration test 168 hours, he the total value is 6 times more likely to be many, but the voltage is still the same. This also means that yueqing the fountain electrical cold-press terminal with the wire frame can not maintain. His air tightness can undertake assignments in a diverse environment, such as temperature, humidity and so on can be a long time to the use of cold pressed terminals for homework, he's won't produce any negative effect.
