Terminal introduction


 

Terminal is a kind of accessory product that is used for electrical connection, and the industry is divided into connectors. As industrial automation becomes more and more stringent and more stringent, the use of terminals will gradually increase. With the development of electronic industry, the use of terminal is more and more, and the variety is more and more. The most widely used are the PCB terminals, hardware terminals, nut terminals, spring terminals, etc.



Historical development


In 1928, phoenix contact invented the world's first piece of modular terminal, this is the prototype of the modern terminals, is also the first phoenix contact to apply for and obtain a patent for invention. Since then, the phoenix electric passion for innovation, committed to the development of all kinds of connection technology, formed the perfect electrical interface technology system, many products has become the industry standard.


define


Terminal is applied for the convenience of the connection wire, it is actually a seal inside the insulation plastic pieces of metal, with a hole at both ends can be inserted into conductor, a screw is used to tighten or loosen, such as two wire, sometimes need to connection, sometimes need to disconnect, then connect them can use the terminal, and can be disconnected at any time, without having to weld them up or intertwined, very convenient. And suitable for a large number of wires connected, in the electric power industry is a special terminal, terminal box, above all terminal, single, double, current, voltage, ordinary, can be broken, and so on. A certain amount of pressure is required to ensure reliable contact and to ensure sufficient current.


classification



Terminals can be divided into WUK terminals, european-style terminal series, plug terminal series, transformer terminal blocks, wiring terminal buildings, fences terminal series, spring loaded terminal series, rail type terminal series, the series of wear wall type terminal blocks, etc.


Plug type


Part of the wire is pressed and then inserted into the other part, which is attached to the PCB board. This is the mechanical principle of the bottom, which ensures the reliability of the product's long airtight connections and the use of finished products. Can add assembly ears on both ends of the socket, assembling the ear to a large extent can protect splicing and can prevent the splicing arrangement position, at the same time, this design can ensure outlet socket right into the matrix. The socket can also have the assembly button and lock position. The assembly button can be secured to the PCB board more firmly, and the lock position can lock the mother and socket after the installation is complete. All kinds of socket design can match different maternal insertion method, for example: horizontal, vertical or inclined to printed circuit boards, etc., can choose different ways according to the customer's requirements. It is the most popular terminal type on the market that you can choose the metric line.


Fence type


It is a safe, reliable and effective connection, especially in high current and high voltage use.


Spring loaded


It is the new terminal of the spring device, which is widely used in the world electrician and electronic engineering industry. Lighting, elevator lift control, instrumentation, power supply, safety and industrial control.


Wear a wall



Using screw connection technology, the insulation material is PA66 (flame retardant grade: UL94, v-0), the connector adopts high quality conductive metal material.

H wear wall type terminals can be installed side by side in 1 mm to 10 mm on the thickness of the panel, such as the distance can be adjusted automatically compensate panel thickness of any number of terminals, and can be used to separate board to increase the air clearance and creepage distance. Without any tool, you can install the wall type wire terminal securely on the panel and make it extremely convenient.
