Terminal Blocks - Wire to Board

Terminal blocks are multi-conductor electrical connection blocks that allow multiple electrical devices such as bare wires and cables to securely connect to a single location. They are commonly used in a wide range of applications, from household appliances and industrial electronics to computers, automotive and aerospace applications.

Terminal blocks provide a secure connection between the power supply and the electrical device, and can reduce wiring time and improve safety. They come in a variety of sizes and shapes to meet different application requirements.

1819079 Application Field and Working Principle

Terminal blocks are available in different types and configurations for various types of electrical applications, including Wire to Wire, Wire to Board, Board to Board, and Wire to Tubing.

Wire to Board

Wire to board (W2B) or board to board (B2B) terminal blocks have multiple types of contact designs including screw terminals, one and two-piece design clamping, pressure spring and spring types. They are used for many applications, such as PCB assembly, building intercom systems, remote control, audio and alarm systems, and communication systems.

These applications require a secure and reliable electrical connection between two or more components. W2B/B2B terminal blocks provide the connection and are typically used to connect multiple wires to a printed circuit board (PCB). The terminal blocks have contacts that protrude into the PCB in order to make a secure and reliable electrical connection.

The W2B/B2B terminal blocks are typically composed of an insulating base, a contact system, an electrical barrier system, and external wiring. The insulating base is a non-conductive material that provides the basic support and shape of the terminal block. The contact system is made from metals such as copper, brass, steel, nickel, etc. The electrical barrier system provides an electrically and thermally stable connection between each wire and the contact system. The external wiring can be made of a variety of wires such as bare copper, PVC, and polyethylene.

The W2B/B2B terminal blocks are used to connect two or more components by means of soldering, welding or crimping. The terminal block is then secured to the PCB by soldering, welding or crimping. The wires are then connected to the contacts on the terminal block using options such as insulation-displacement technology.

The W2B/B2B terminal blocks are rated for a range of current and voltage levels, depending on the application requirements. For example, some may have a current rating of up to 5A, while others may have a voltage rating of up to 500V. The terminal blocks also come in a range of sizes to accommodate wires of different sizes and shapes.

W2B/B2B terminal blocks are an essential component of any electronic system. They provide a secure and reliable electrical connection between two or more components and can save valuable time and improve safety when properly installed and used.
