FAQ

What advantages does PAXT Electronics have in the terminal block industry?  

PAXT Electronics is a technology-based company integrating production and research. We can proceed evaluation and production through the whole process from product development to automated mass production.  We have a professional sales engineering team, facilitating project cooperation with our customers from the R&D side. So whether from R&D capability or sales team or business cooperation, we firmly believe that we have more advantages.

How to avoid plug and socket misplug for same poles pluggable terminal blocks

1. different colors;
2.add printing on the products;
3. add anti-misplug accessory;
4. add the orientation structure in different locations;
5. add empty poles or distinguished from poles.

What are the common electro-plating methods of terminal blocks?

A.Continuous plating:

put the plating strips into the plating tanks already planned. For parts that are easily deformed during electro-plating process, we will first Continuous plating the plating strips, then start the forming process.
B.Barrel plating:
Put the bulk plating parts into the drum, and then put the drum into the plating tank for electroplating, which is a conventional process for most products
C.Hanging plating:
Put the plating parts in the rack, and then the rack is placed into a plating tank for electroplating, suitable for large volume or weight product so as to prevent deformation or coating damage resulting from plating parts colliding with each other during electroplating process.

What are the factors that lead to aging of terminal blocks housing?

A.Environment and temperature:
The application environment and heat sources of terminal blocks could lead to too high temperature, insulated breakdown, and even explosion.
B.Chemical Corrosion:
Due to long-term chemically corroded or electrolytic corrosion, the housing insulation material of terminal blocks is affected, resulting in the failure of the protective layer, the insulation is reduced, and the terminal blocks aging is aggravated.
C.Long-term overload operation:
Due to the thermal effect of the current, the temperature of the terminal blocks( with load current)will be raised, and the excessive temperature accelerates the aging of insulation, especially in the summer, the aging of terminal blocks will be exacerbates.
