The Relationship Between Contact Force And Ferrule Terminals

Contact force is one of the elements in cold-pressed terminal blocks. If we do not have sufficient contact force, then no matter how good our conductive material is, it is useless. For example, if our contact force is very low, then there will be a displacement between the wire and the conductive sheet, which will cause oxidation pollution to appear, and the contact resistance will increase. Therefore, we will not be affected by other effects when using cold-pressed terminals.
The cold-press terminal uses a crimping frame, so it is very reliable. When we tighten the screw again, its threaded tongue will spring up, so that there will be a reaction force of the screw. . This is actually caused by the temperature, we don't need to tighten the screws.
If the crimping frame of the pressed wire is aged in 168 hours of operation, it will also undergo a 168-hour vibration test in 20 times the gravity, and its total value will be more than 6 times higher , but its voltage remains the same. This also means that the cold-pressed terminal block does not need to be maintained if the crimping frame is used. Its airtightness can work in a variety of environments, such as temperature, humidity, etc., can be used for a long time to work with cold-pressed terminal blocks, and it will not have any negative effects.
