Wiring terminal is a kind of accessory product used to realize electrical connection. It is divided into the category of connector in industry. With the higher and higher degree of industrial automation and the more strict and accurate requirements of industrial control, the consumption of wiring terminals is gradually increasing. With the development of the electronic industry, more and more terminals are used, and there are more and more types. At present, in addition to PCB board terminals, hardware terminals, nut terminals, spring terminals and so on are widely used.
Historical development
  in 1928, Phoenix Contact invented the world's first combined wiring terminal, which is the prototype of modern terminal and the first invention patent applied for and obtained by Phoenix Contact. Since then, phoenix contact has been passionate about innovation, committed to the development of various connection technologies, and formed a perfect electrical interface technology system, many of which have become the application standards of the industry.
definition
   the wiring terminal is used to facilitate the connection of wires. In fact, it is a metal sheet sealed in insulating plastic. There are holes at both ends to insert wires, and screws are used to fasten or loosen. For example, two wires sometimes need to be connected and sometimes need to be disconnected. At this time, they can be connected with terminals and disconnected at any time, It is convenient and fast without welding or winding them together. Moreover, it is suitable for a large number of wire interconnection. In the power industry, there are special terminal blocks and terminal boxes, all of which are wiring terminals, single-layer, double-layer, current, voltage, ordinary, breakable and so on. A certain crimping area is to ensure reliable contact and sufficient current.
