Screw PCB terminal block introduction.

2022-12-15

Main Functions:
For transmitting electrical signals and conducting electricity.

Main material:
Phosphor copper, Brass/Cu, Steel/Iron, Stainess steel/Steel, Aluminium/AL, etc.

Environmental protection:
There are ROSH and non-ROsh.

Surface treatment:

Tin plating, silver plating, gold plating, nickel plating, galvanizing, pickling or anodizing.


Tin plating, nickel plating, silver plating and gold plating are generally suitable for copper products to improve the electrical conductivity of the products, of which the electrical conductivity is the best; Galvanized is often used in iron products for rust prevention, of course, other electroplating also has the function of rust prevention; Stainless steel is often used in pickling terminals, it can maintain the metal color and by the short term can play the role of rust prevention, admittedly, it can also be used in other plating treatment; Anodic treatment is generally for aluminum products, the colors are beautiful red and green and so on.

Terminal crimping: Good crimping of wire and terminal can reduce the resistance and copper wire oxidation, and make it firm and not easy to open and loose after tight crimping, with excellent electrical conductivity, solid crimping should pay attention to whether the mold magazine or loose, the employee's control gesture or terminal is in place.

The screw connection is still the mainstream of industrial connection technology. Other joining techniques cannot provide as much compression in such a small space as screw connections. Screw self - locking system prevents accidental loosening of connections. The operation is very simple. Only a screwdriver is needed to complete the operation of wiring screws and Bridges.

With high quality contact materials, long-term reliability is maintained even in harsh environments such as erosive air. Screw connection is indispensable in high current situations. The 240mm2 terminal block can bear more than 400A working current.
