Terminal Blocks - Headers, Plugs and Sockets - Application Field and Working Principle
The terminal block, also known as the electrical distribution block, is a type of electrical connector, which is designed to connect two or more electrical paths. Headers, plugs and sockets are specialized types of terminal blocks specifically designed for different types of applications, such as connecting different components inside electronic and power-distribution systems. This article discusses the application field and working principle of these terminal blocks.
The terminals are widely used in almost all kinds of electronic products like machines, computers, telecommunication systems, instruments and other equipments. One of the oldest and most widely used terminal block is the pluggable header, used as a general-purpose connection for any type of electronic signal. Headers usually are available in both single and double row design and with various pin numbers. Plug and socket type terminal blocks are another common type and are specially manufactured with an interlocking function, allowing users to securely join two terminal blocks together without the use of any other securing device. For higher power applications, such as power distribution in industrial machines, power boards and control panels, special purpose terminal blocks are available that are designed to handle high-amperage and high-voltage current and include additional features such as disconnection and short-circuit protection.
The working principle of a terminal block is based on three main properties: electrical conductivity, good insulation, and secure mechanical connection. Most terminal blocks are made up of a wire conductor, an insulator, and a terminal. The wire conductor is typically made from metal while the insulator is often a plastic, ceramic, or rubber material. The terminal is generally a piece of metal that is connected to the wire and designed to create a secure mechanical connection. Once the wire is connected to the terminal, an electrical connection is established which allows the current to flow from the wire to the terminal. The insulation surrounding the wire conductor helps to keep the current from short-circuiting or traveling to other portions of a circuit.
Terminal blocks are available in a wide range of sizes, shapes, materials, and design features, allowing them to be used in a variety of applications. Some of the most popular terminal blocks include single and double row headers, plugs, and sockets. Small single row headers, for instance, are typically used in small electronic products, while industrial control and power distribution systems use larger double row headers. Pluggable headers and sockets are typically used in telecommunications applications, while power boards and control panels typically use power boards and plugs specifically designed for higher-amperage, high-voltage applications.
Terminal blocks are also available with a variety of features such as disconnection, short-circuit protection, and over-voltage protection. Disconnection refers to the ability to quickly and easily remove the terminal block from the circuit, while short-circuit protection prevents current from flowing from one circuit to another and potentially causing damage or a fire. Over-voltage protection is typically used in more complex systems where multiple terminals need to be connected and power regulated. This type of protection ensures that no excessive voltage is delivered to an individual terminal, protecting both the terminal and the other connected terminals.
In conclusion, terminal blocks are widely used in all types of electronic products and for diverse applications. The most common types include single and double row headers, plugs, and sockets, which are available in a variety of sizes and designs. Depending on the application, additional features may be needed such as disconnection, short-circuit protection, or over-voltage protection. With a wide range of sizes, materials, and features, these terminal blocks make it easy to securely and reliably connect different circuits, components, and power sources together.
