Terminal blocks, also known as barrier strips, are printed circuit boards that provide a secure connection for electrical wires and cables. They are designed to help protect delicate electronic components from vibrations or electrical shocks, resulting from a live circuit. Terminal blocks typically have a small, inline body, which can be relatively compact and lightweight, making them a more space-efficient solution than traditional wiring looms. In addition, they can be used for both single-wire and multi-wire connections depending on the application.

Wire to board terminal blocks are designed to connect wires to termination points on a printed circuit board (PCB). This terminal block type can provide a secure connection that is reliable and vibration resistant. Wire to board terminal blocks are available in a variety of styles and sizes to suit different PCB designs, panel sizes, and wire gauges. Most feature either a screw or a spring clamp force connection.

Wire to board connections, with terminal blocks, are typically done with a series of insulation-displacement contacts or IDCs. For this type of connection, a wire is inserted into the terminal block contact which then slices through the insulation of the wire, making a direct connection with the conductor. This is a very robust type of connection, as it eliminates fragility from tension force connections. The IDC connection type of wire to board terminal blocks can also typically be reused multiple times.

Terminal blocks are typically available in black, white, ivory or gray plastic. They can feature connection points that are either open or closed, and either wide or narrow. Open connection points are essentially a plastic insulating block that accommodates an array of electrical terminal connections such as screws, lugs, spade lugs, forks, and eyelets. A closed connection point can be created with a clip, allowing a quicker assembly.

The common connection method in a wire to board terminal block is contact force. This method is achieved by an electrically conductive strip that slides into a cavity in the terminal block. When the strip is inserted into the aperture, the two assembled pieces of the terminal block are then force- connected. For single-wire connections, contact force terminal blocks are also available as single-side or dual-side assembly.

Wire to board connectors come in various sizes, shapes, and colors, allowing them to be used in a variety of applications. They are commonly used in industrial, automotive, and consumer electronics applications. When selecting a terminal block, it is important to consider the number of connections and the maximum current they must carry. It is also important to consider the application environment, as terminal blocks should match or exceed the voltage and environmental requirements of the application.

Terminal blocks are notoriously easy to use in applications requiring multiple wires. They provide a reliable way to secure electrical wiring and reduce the number of electrical connections and the required space for electrical boxes and enclosures. Furthermore, small, easily installed terminal blocks offer the flexibility to make almost any type of connection configuration, including single-wire connections for basic signals or high-current, multiple-wire connections.

Terminal blocks, such as wire to board terminal blocks, serve as a reliable and essential connection point for virtually any type of electronic equipment. They are designed to provide a safe, secure, and reliable electrical connection, and they offer improved flexibility for panel and wiring configurations. Wire to board terminal blocks come in various shapes, sizes, and colors, and offer contact force and insulation- displacement options to provide the ultimate in electrical connections.
