Terminal Blocks - Wire to Board is a technology used to connect electrical wiring to circuit boards. This technology uses the principles of two different types of components, namely terminal block connectors and board to board connectors, to achieve the connection between two pieces of electrical circuit board. Terminal Block connects two or more wires, while board to board connector creates a connection on a printed circuit board. Combining these two elements results in a reliable wire to board connection.

Terminal Blocks are usually made from molded thermoplastic or machined metal components. The most common materials used are polycarbonate, nylon, aluminum, and brass. These materials are generally chosen because of their ability to provide excellent electrical and mechanical performance. All materials used in Terminal Blocks are rated for their electrical insulation properties, providing protection from electrical shock and short circuits.

The two main styles of operative spring or PCB terminal blocks are screw style or spring style. Screw style terminal blocks for PCB are designed to be screwed onto a printed circuit board with a manual or electric screwdriver. As the screw is tightened, a force is applied to the contact surfaces of the terminal block and the PC board, making a secure electrical connection. Spring style terminal blocks for PCB use a spring-loaded plunger that makes contact with the solder pad on the underside of the board. When the board is inserted into the terminal block, the plunger is compressed and creates the contact between PCB and block.

Terminal Blocks can be used in a wide variety of electrical and electronic applications. The most common application is in the connection of power or sign elements on the PCB. Terminal Blocks are suitable for the connection of high power equipment such as motors and lighting systems. They are also used in audio and visual systems, such as television and home cinema, where the terminal blocks enable audio and video signals to travel between the components. The use of terminal blocks is also increasingly common in communications equipment, such as modems and fax machines. Additionally, terminal blocks are commonly used in the testing and validation of printed circuit boards in order to ensure proper connections.

Terminal Blocks are designed to offer superior electrical performance and mechanical protection. The blocks are typically made from metals or polymers, providing excellent mechanical resistance and high insulation value. Furthermore, the design of the block ensures that it can withstand shock and vibration. As such, terminal blocks are commonly used in the automotive industry due to their robust design and superior performance.

In summary, Terminal Blocks - Wire to Board technology provides a reliable and cost effective way of connecting two pieces of electrical circuit board. The blocks provide excellent electrical and mechanical performance and their design ensures that they can withstand shock and vibration. This technology is used widely in the automotive, communication, and audio and visual fields.
