Tips: Why the insertion/withdrawal cycles of the heavy-duty connector are 500 times?
The contact resistance of heavy duty connector is mainly composed of three parts: conductor resistance, shrinkage resistance, and film resistance. The conductor resistance is usually very small (10-8mΩ) and is usually ignored in the calculation. The actual contact resistance usually only considers shrinkage resistance and film resistance.
In the range of ≤500 times, the contact resistance change is relatively stable, because the surface film of the contact is continuously damaged at this stage, and the gold plating layer and the parent metal on the surface of the contact have not started to wear. The film resistance in the resistor will continue to drop, so the contact resistance at 500 times will be lower than that at 250 times. After more than 500 times insertions and withdrawals, the reason for the increase in contact resistance is that with the increase of insertion and withdrawal, the surface coating of the contact body and the continuous wear of the substrate causes the contact surface to be rough, and the contact area is reduced. The elasticity of the contact ring decreases, and the positive contact pressure decreases during insertion and withdrawal, resulting in an increase in contact resistance.
What to do if the customer requires a higher number of insertions/withdrawal cycles?
The simplest method: On the one hand, use a solid film protective agent on the contact body. On the other hand, pay attention to avoid contact with hydrocarbons during connector assembly and use. These two methods are actually to avoid or reduce the generation of film resistance, in order to achieve the purpose of increasing the number of insertion and withdrawal.
