Terminal blocks, also called terminal boards or strips, are modular components used for the connection, routing, and termination of electrical wires. They are the ideal choice for applications where multiple wires need to be connected in a quick and reliable way. Terminal blocks are available in a range of materials and designs, with options to meet the requirements of virtually any application. To help simplify the selection process, terminal block categories are divided by their primary use cases. This article will explore the specific application areas and working principles of terminal blocks in the "Wire To Board" category.

Terminal blocks from the Wire To Board family are primarily used in applications where light to medium-duty wiring is required. They feature wire entry at one end and contact terminals at the other. Wire To Board terminal blocks are often used in building and equipment control panels, electronic test fixtures, and other projects that require secure and reliable connections. As opposed to the larger heavy-duty terminal blocks, Wire To Board products are typically small and lightweight, so they are ideal for installations in cramped or confined spaces.

Wire To Board terminal blocks come in a variety of designs for different applications. For example, there are terminal blocks with two or three levels of contact, depending on the amount of wire lanes needed. Some products are designed with integral or quick-disconnect termination, allowing for easy joining, installation, and removal of wires. There are also terminal blocks designed with insulation displacement connectors (IDCs) for ribbon cable wiring systems.

When it comes to mounting and installation, Wire To Board terminal blocks offer several additional features. There are terminal blocks with screw-clamp or spring-clamp terminals for easy and secure mounting. There are lockable and self-locking variations that can increase the safety of the connection. For easier layout and identification, labels can be quickly applied to labeled terminal blocks. Many products also come with pluggable connectors, allowing for fast and easy assembly.

The working principles behind wire-to-board terminal blocks are fairly straightforward. A wire is inserted into a terminal opening at one end and contacts a metal terminal at the other end. On a basic level, the wire is securely held in place, creating an electrical connection with the terminal. Depending on the type of terminal block, the contact can be made with a spring-clamp, screw-clamp, insulation displacement connector, or another type of terminal.

The great advantage of wire-to-board terminal blocks is the modularity. Once individual wires are connected, the entire terminal block can be rapidly rewired or repositioned. This flexibility and convenience make Wire To Board terminal blocks an ideal choice for many types of equipment and applications.
