Terminal Blocks - Wire to BoardTerminal blocks are a type of electrical connection that consists of a fixed or removable insulated body. Terminal blocks offer quick and easy ways to connect electrical wires to a system or device. These blocks provide an efficient, dependable, and cost-effective manner of connecting electrical wiring. Terminal blocks are typically used in applications where it is not feasible to use permanently attached cables. The terminal block is also an ideal option for applications where it is desirable to make changes or adapt the wiring system periodically, as the blocks allow wires to be quickly connected or disconnected. Terminal blocks are manufactured with several different featured options, that can be chosen depending on the application needs. This includes options such as:• Fastening elements, such as tension clamp, adhesive, or screw terminals • Leveling elements to enable the wiring of rows or columns that contain several connections • Electrical separation between the contacts for complete insulation • Springs to enable a reliable contact and connection • Special contact materials, such as three-level or gold-plated terminals • Adapter plates or integrated mounting options Terminal blocks are available in various sizes and configurations, which are designed according to their application requirements. Generally, terminal blocks are standardized into one of three categories according to the type of connecting wires they are designed to handle: Wire to Board (WTB), Wire to Wire (WTW), and Board to Board (BTB).Wire to Board (WTB) terminal blocks are designed to interconnect wires into a printed circuit board (PCB). This type of terminal block is the most commonly used for various types of electronic and electrical equipment. They can be used for convenient plug-in connections of discrete wiring when changing over to different wiring configurations. Generally, these terminal blocks feature a molded plastic body, and are available in different sizes. WTB terminal blocks are split into two or three pieces and it is easy to break apart for easier disposal or re-use. They are also available in a variety of terminations for various application requirements. For WTB terminal blocks, wire connections are made by inserting the wire into the block so that the wire is firmly held in place by springs or tensioning devices. A physical connection is achieved by screwing the terminal blocks together to compress the spring on the wire. This ensures that a secure contact is made between the wire and the block.These types of terminal blocks are most often used in the connections between power, control, and signal cables in control panels, servo motors, inverters, and other equipment. WTB terminal blocks also provide a convenient and economical method of quickly connecting and disconnecting wires without the need for any special tools.In summary, Wire to Board (WTB) terminal blocks are versatile electrical connection components that are designed to interconnect wires into a printed circuit board (PCB). They feature a molded plastic body, and are available in different sizes, configurations and terminations for various application requirements. WTB terminal blocks are split into 2 or 3 pieces and feature physical connections that are made by screwing the terminal blocks together to securely contact the wire. They are the most commonly used terminal block and are used for applications such as control panels, servo motors, inverters, and other equipment.
