Terminal Blocks - Wire to Board refers to an interconnection technology for the physical connection of a wire to a printed circuit board (PCB). It is composed of a series of metal connection blocks which provide a mechanical connection between wires and a PCB. Terminal Blocks come in a variety of sizes, shapes and pin types, and are used in a variety of applications, from interconnecting low-voltage circuits, to power distribution and high-voltage signal connections. This article will discuss the application field and working principle of Terminal Blocks - Wire to Board, as well as the types of materials used, and the advantages and disadvantages of this connection technology.
Application Field and Working Principle
Terminal Blocks - Wire to Board has been widely used in many industries as a reliable connection method for electrical wiring. For example, it is widely used in wireless communication device, display apparatus, industrial control, and consumer electronics, among other application areas. Typically, it is used in situations where high currents and voltages have to be managed, and low contact resistance is required.
The way a Terminal Block - Wire to Board connection works is relatively simple. A preformed metal connection block typically contains an insulation base, two metal pins spaced apart, and an enclosed spring clip. The insulation base is the part of the connection block that is secured to the printed circuit boards, while the two pins are designed for wires to be inserted into. Once the wires have been inserted into the pins, the spring clip is compressed to create a secure electrical connection between the wires and the board. By this method, currents and voltages can be distributed or transmitted through the connection.
Materials Used
Terminal Blocks - Wire to Board connections are typically made up of several different materials including plastic, metal, and sometimes ceramic. These materials are chosen based upon their ability to both transfer electricity effectively and resist corrosion. Plastic is typically the main material used, due to its light weight and good insulation properties. Metals such as brass and tin-plated steel are also used for their electrical conductivity and durability. Lastly, some Terminal Blocks - Wire to Board connections are made of ceramic due to its superior heat and fire resistance.
Advantages and Disadvantages
Terminal Blocks - Wire to Board connections have a variety of advantages as well as some drawbacks. On the positive side, this connection technology is much more reliable than wire stripping and soldering as it provides greater accuracy and security. Furthermore, it is more efficient and easier to work with than other connection methods, with fewer components needed for assembly. Additionally, this technology is able to handle different current and voltage requirements, making it suitable for a wide range of applications.
The downside to Terminal Blocks - Wire to Board connections is that the connection can be quite bulky as there are a large number of components involved. Furthermore, some materials used do not easily conform to the board’s shape, which leads to greater difficulty during assembly. Finally, this slower than other connection methods, and the added assembly steps required can lead to errors.
Conclusion
Terminal Blocks - Wire to Board is a widely-used connection method for electrical wiring. It consists of a series of metal connection blocks which provide a mechanical connection between wires and a PCB. The connection works by inserting the wires into the pins of the connection block and using a spring clip to compress them. It is made up of several different materials including plastic, metal, and sometimes ceramic. Advantages of this connection technology include accuracy and security, as well as efficiency and ease of use. However, the bulky nature of the connection and additional assembly steps required can lead to errors.
