Terminal Blocks - Headers, Plugs and Sockets

Some of the most common terminals used in electrical interconnection systems are terminal blocks, also known as headers, plugs and sockets. Terminal blocks are most commonly associated with both the power supply side (headers) and the control/load side (plugs).

Terminal Block headers are commonly used as the power part of the terminal block connection system. They provide a direct connection between the power supply (cable or bus-bar) and the load side terminal. Power terminal blocks, therefore, provide a safe connection for high currents and provide insulation from voltage and current spikes. They are typically used for connections between the terminals of a generator and the cables connected to a motor.

Terminal Block plugs are suited for low or low-to-medium current applications and are also used for connecting load side devices such as wiring boxes and distributor systems. Plugs are often used in areas such as the control panel of electrical devices, automation systems, and in testing applications. They tend to be low cost and coms with a variety of designs and features which make them suited to various applications.

Terminal Block sockets are generally used to connect the power side of a terminal block connection system to a device. They connect the power supply to the load device in a safe and reliable way, providing electrical insulation and protection, vibration resistance, shock resistance and electromagnetic interference protection. They are often used to transfer power to large machines such as pumps, machines in the medical or refrigeration industry, or high voltage equipment.

1853081 application field and working principles typically use terminal blocks in a variety of industries. They are used in industries such as automotive, medical, telecommunications, data management, computer, and instrumentation. Their use in these industries is due in part to their low cost, safety, and convenience. They provide a secure connection for both the power supply and the load side, protecting against voltage spike and current surge. They also provide a means for easy connection and disconnection for circuit testing or maintenance.
