The first printed circuit board terminal block was born in 1970. With the birth of terminal blocks produced by Phoenix Contact in 1982, the prototype of modern terminal blocks was established. With the development of the electronics industry, the types of terminal blocks There are more and more types of terminals, which can be divided into European terminal blocks, plug-in terminal blocks, fence terminal blocks, spring type terminal blocks, track type terminal blocks, through-wall terminal blocks...
As far as the current development of science and technology is concerned, the best science and technology will fall behind one day. The rapid development of science and technology is an inevitable trend. Science and technology originate from social practice and serve social practice. Modern science is flourishing in a better and better direction. Development, the times are constantly changing, and technology is constantly innovating. We, humans, have been groping on the road of science and technology. This road is full of challenges and obstacles. Every progress of the times will surprise us. There are big and small innovative things. Although some things are small, they are not small, just like terminal blocks, a simple device composed of plastic and metal sheets, which allows electrical and mechanical The industry is very useful.
Let's first talk about what is a terminal block. In fact, the terminal block is used to facilitate the connection of wires. It is actually a piece of metal sealed in insulating plastic. There are holes at both ends for inserting wires, which can be fastened or loosened with screws. For example, two wires need to be connected. Or when they are disconnected, they can be connected or disconnected with terminals without having to weld them or twist them together, which is very convenient and quick. It is suitable for a large number of wires to be connected to each other. In the power industry, there are special terminal blocks and terminal boxes. The above are all terminal blocks. There are single-layer, double-layer, current, voltage, ordinary, and Can be broken, and so on. A certain crimping area is to ensure reliable contact and to ensure that sufficient current can pass. In a word, the terminal block occupies an important position in the process of machine operation, and the terminal block must conform to the label to avoid accidents.
In fact, our current life, work, entertainment, and the like are completely dependent on electricity. Without electricity, work, life, and entertainment will be interrupted and will stagnate. Cell phones, computers, cameras, and many other electronic digital products and household electrical appliances. The common feature of these products is the use of electricity, and the most important thing is that they are equipped with a variety of wires, white and black, long and short, thick and thin. Power lines, data lines, and various lines are connected to the electronic products we need to use so that they can work normally and perfectly to achieve the services and functions we want.
At present, these various lines all have a port, and they use these ports to connect with various devices. For example, the network cable has two crystal heads, one end is connected to the switch, and the other end is connected to our computer. The crystal head is terminal. The USB interface of the data line is also a kind of terminal block. One end of the charger is connected to the power supply, and the other end is connected to the computer and mobile phone. These ports are also high-current terminals. There are thousands of types of terminal blocks, and there are more than 3,000 types of terminal blocks of a certain well-known brand.
In addition to the application of terminal blocks in computers, digital products, household appliances, etc., all plugs or ports connected to the power supply can be called terminal blocks. The application fields of terminal blocks are staggering. Terminal blocks have reached the point where they can be seen everywhere in daily life. Therefore, the market for terminal blocks is very large. Cixi Kangfei Electronics is a professional manufacturer of terminal blocks. The terminal blocks are of good quality, low price, and good service. Welcome to visit and purchase.
Screw-type terminal block, its structure and design are stronger, which has the characteristics of convenient wiring and reliable screw connection;
1) The terminal block has a compact structure, reliable connection, and has its own advantages;
2) Utilize the lifting principle of the clamping body to ensure reliable wiring and large wiring capacity;
3) The welding foot and the clamp body are divided into two parts to ensure that the distance when the screw is tightened will not be transmitted to the solder joint and damage the solder joint;
4) The shell is strong and reliable, and the needle pitch is accurate.
