Terminal Blocks - Wire to BoardTerminal blocks are electrical components used to join conductors from a wire harness to electrical devices or appliances. Usually, terminal blocks are mounted on boards or panels and consist of two or more pins. Often, they can also be used to interconnect long-distance wiring. With their diverse range of applications, terminal blocks are essential components for any electronics project.The wide range of terminal blocks available can be classified based on two main criteria: Wire to Board (WTB) and Board to Board (BTB). WTB models are designed to join wires to printed circuit boards (PCBs). This type of terminal blocks is generally used in appliances that require frequent connections and disconnections. On the other hand, BTB models are used to connect two printed circuit boards that have been designed for easy isolation of components.In the WTB terminal block category, three main designs are available: screw, clamp, and spring-clamp. The main difference between these types of terminal blocks is the way they secure the electrical wires. The screw design has two-piece construction with external screws used to secure the wires in place by tightening the blocks. The clamp and spring-clamp designs require the user to squeeze the clamping mechanism to secure the connection.The application fields of terminal blocks in the WTB category are varied and include appliances for residential, industrial, and commercial use. Commonly, they are used to connect and attach AC power supplies, terminal strips, grounding leads, and low voltage lighting controls.The working principle of a WTB terminal block is determined by its design. In general, all terminal blocks use screws, clamps, or spring clamps to fix the connected wire, and a specific voltage rating to provide a safe connection between the power supply and the electrical device.For screw designs, tightening the screws on the terminal block provides a secure connection between two wires. The two metal pieces, insulated from each other, forces the wire into two separate contact points, closing the connection and establishing electricity flow. This type of terminal block also has multiple layers for each electrical connection, which can help to protect the wiring from bending, vibration, and other external forces. For the clamp and spring-clamp designs, the two-piece construction enables the user to apply enough pressure to make electrical contact between the two wires. The block pieces are designed in a way to enable the user to easily secure the wire with minimal effort. Connecting the wires via a clamp or spring-clamp design utilizes a metal-encased spring to ensure the electrical connection between the two wires. In industrial applications, terminal blocks are widely used as interconnecting or distribution points in big installations. Their robust construction, multiple contact points, and the ability to easily disconnect the wires makes them an ideal choice for this purpose. WTB terminal blocks commonly have a terminal strip, a housing, and a locking mechanism that allow for easy mounting onto the device or appliance. Overall, WTB terminal blocks are effective components used to join wires to printed circuit boards in different applications. They provide a secure connection of wires and help protect them from external forces. Their robust construction and easy installation features allow these components to be used in many applications around the world.
