Terminal Blocks - Wire to Board

Terminal blocks, also known as terminal strips, are electrical connectors designed to connect wires together and are used in a variety of applications. A terminal block – wire to board is an electrical interface component that connects multiple wires of a specific electrical circuit to a circuit board via a single mating connector. It consists of a series of parallel rails that are installed onto a printed circuit board, which act as connection points for circuits mounted on the board.

Advantages of using a terminal block-wire to board

• Simplified circuit assembly – Since the wires terminate into the board, it eliminates the need for cable assemblies and other wiring techniques.
• Improved component routing – With a terminal block – wire to board, the interconnections between components are secured four times better than standard wiring. This prevents unintentional disconnection and makes the circuit more reliable.
• Reduced downtime – Terminal blocks – wire to board reduces circuit disruption when troubleshooting, as it is capable of providing quick access to specific connections and also has a secondary access point for testing.
• Reduced complexity – By connecting all the wire terminals onto the board in one spot, it eliminates the need for complicated wiring and associated costs associated with it.
• Space saving – By eliminating the need for complex and expansive wiring, the circuit board can be further packed within a smaller form factor.

Types of terminal block-wire to board

There are various types of terminal block-wire to board available including single row, dual row, flat power, PCB mountable, surface mountable and Euro-style. The type of terminal block to be used in an application entirely depends on the number of wires to be connected, the contact force to be applied, the type of connection being made and the environment in which it will be installed.

Working principle of a terminal block-wire to board

A terminal block – wire to board consists of two modules – the board and the terminal. The board module is a flat base that is installed on the printed circuit board and is used to hold the terminal blocks. The terminals blocks comprise of the pins which are designed to accept incoming wires.

The connection is established by connecting the wire to the terminal block – wire to board. Then, the block is placed into the board module and the terminal is secured. When the pins are secured to the board, the electrical circuit is established. The wire is then stripped of its insulation and the exposed wire is inserted into the terminal.

Applications of terminal block-wire to board

Terminal blocks – wire to board are used in a wide variety of applications due to their simplicity, space saving and improved contact reliability. Some of the common applications include power distribution, signal routing, computer networks, telecommunications, automotive electrical systems, electronic appliances, industrial control systems, and audio-visual products.

Terminal blocks – wire to board offer an efficient and cost-effective way to connect multiple wires within a single module. This type of connection reduces the complexity of wiring and ensures that the connection is secure and reliable.
