The production of terminal connectors involves plastic injection molding, metal stamping, and subsequent maintenance stages. Scientific production and maintenance ensure high-quality terminals with extended service life.

Several factors can lead to the aging of terminal connectors:

Chemical Erosion

The insulation material of the terminal housing is subject to chemical or electrolytic corrosion over time, leading to the failure of the protective layer, reduced insulation, and accelerated aging of the terminal.

2. Extended periods of overloading

Due to the thermal effect of current, the load current passing through the terminal connections inevitably causes heating, leading to an increase in the temperature of the terminal connections. Excessive heat accelerates the aging of insulation, especially during summer when the aging of the terminal connections intensifies.

3. Environment and Temperature

The external environment and heat sources surrounding the terminal block can also lead to excessively high terminal block temperatures, insulation breakdown, and even explosions and fires.
