Terminals

Terminal block is an accessory product used to realize electrical connection, which is divided into the category of connector in industry. With the increasing degree of industrial automation and the stricter and more precise requirements of industrial control, the amount of terminal blocks is gradually increasing. With the development of the electronics industry, the use of terminal blocks is increasing, and there are more and more types. In addition to PCB board terminals, the most widely used ones are hardware terminals, nut terminals, spring terminals and so on.

copper bar

Copper busbar is one of the main varieties of copper processing materials. Copper busbar has high mechanical properties, good electrical conductivity, thermal conductivity, excellent corrosion resistance, electroplating, brazing, beautiful and beautiful metallic luster and good forming performance, etc. Power transmission and transformation, electrical equipment, etc. have been widely used in the field of electric power. In recent years, with the sustained and rapid development of the national economy, the output and consumption of copper busbars in my country have also increased significantly, and the quality requirements for copper busbars are also increasing.

copper wire

In life, practical copper wire is used as conductor. It has good electrical conductivity and is widely used in the manufacture of wires, cables, brushes, etc.; it has good thermal conductivity and is often used to manufacture magnetic instruments and meters that must be protected from magnetic interference, such as compasses, aviation instruments, etc. It has excellent plasticity and is easy to be hot-pressed and Cold pressure processing can be made into copper materials such as pipes, rods, wires, strips, strips, plates, and foils. There are two kinds of pure copper products: smelted products and processed products.

copper rod

Brass rods are rod-shaped objects made of copper and zinc alloys, named for their yellow color. Brass with a copper content of 56% to 68% has a melting point of 934 to 967 degrees. Brass has good mechanical properties and wear resistance, and can be used to manufacture precision instruments, ship parts, and shells for guns. Different zinc content will have different colors. For example, if the zinc content is 18%-20%, it will be red-yellow, and if the zinc content is 20%-30%, it will be brown. In addition, brass has a unique sound when struck, so Eastern gongs, cymbals, bells, horns and other musical instruments, as well as Western brass instruments are all made of brass.

copper pipe

Copper pipe is also called red copper pipe. A type of non-ferrous metal pipe, which is a pressed and drawn seamless pipe. Copper pipes have the characteristics of good electrical conductivity and thermal conductivity, and are the main materials for conductive fittings and heat dissipation fittings of electronic products, and have become the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial buildings. The copper pipe has strong corrosion resistance, is not easy to oxidize, and is not easy to react chemically with some liquid substances, and is easy to bend and shape.
