The terminal block is commonly used to connect electrical wiring components, mainly from the electrical connection between the devices and components, components and cabinets, systems and subsystems, and the role of signaling, and try to maintain the system and the system does not occur between signal distortion andthe change of the energy loss.

Terminal block is one of the most extensive use of electronic components widely used in computers, telecommunications, network communications, industrial electronics, transportation, aerospace, medical equipment and automotive fields.

With the trend in the development of today's electronics, information technology, the development of the connector industry to create a vast space. Appliances, electronic information products, automobiles, mobile phones and other manufacturing transfer to China, China has become the world's largest home appliance, information products manufacturing center, consumer electronics, network design, communication terminal products and production increased rapidly, so the terminals, and other intermediate products the rapid growth in demand, China has become the fastest growing markets of the global terminal.
