For din 41612 type d connectors wholesale, the application in various electrical components is more extensive. In actual use, the joint is often overheated. For this situation, we can summarize the following reasons:

First, the connector surface protective coating failure, resulting in corrosion of connector contacts.

Second, chemical and electrochemical corrosion: pure metals in the atmospheric environment, due to its thermodynamic instability, have an excessive trend from a high-energy state to a low-energy state, so the corrosion process of metals in the atmospheric environment is a natural law. The corrosion of metals generally exists in two cases, namely chemical corrosion and electrochemical corrosion. Because the speed of chemical corrosion is extremely slow, it will not constitute the main factor of joint heating. The electrochemical corrosion system has its own loop, the corrosion current is generated, so that the anode continues to dissociate, so that the corrosion may continue uninterrupted, so the connector joint area will tend to decrease, and from time to time the deposition film generated and accumulated in the process and the passivation film generated on the anode metal surface will be the contact resistance of the connector joint significantly increases, so that the temperature rise of the joint is significantly increased. And produce a vicious cycle, become the main component of joint heating.

Metal wear: Due to the impact of external force or the thermal expansion and contraction of the metal itself and the fluctuation of the load between the peak and the trough, the contact point of the connector will be less and less. As a result, din 41612 type d connectors wholesale connectors have progressively more corrosion on the contact surface, thus increasing contact resistance and increasing temperature rise at the joint.
