Terminal Blocks – Headers, Plugs, and Sockets – have been used since the 1950s to connect multiple electrical components on a circuit board. Terminals depend on their design to create a safe, reliable connection for power, control, and data signal needs.

Terminal blocks come in various styles to suit unique connection needs and system architectures. Types of Terminal Blocks generally include: Headers, Plugs, and Sockets. Although there are many variations in size and features, this article will clarify the 2713748 application field and working principle of each type.

Headers

Headers are commonly used in power systems to connect a single line electrical load to multiple components. Headers are placed in-between two conductive surfaces and provide insulation to the current from both sides. The lines between electric loads can be extended up to several thousand feet by using headers.

Headers utilize a spring-based contact system for reliable connections. They are compatible with a wide variety of conductors and support numerous amps continuously. Many headers also feature strain relief for cables that may be bent by accident, or over-stretched due to external forces.

Plugs

Plugs are primarily used for low-voltage connections between components or boards. Plugs feature a larger contact than other connectors and can accommodate more data wires or pins as needed. The large number of pins (up to 48) also makes plugs favorable for multiple voltage applications.

For quick connections, plugs have been designed with removable ends. This feature allows for faster setup compared to using headers, as the plug can be inserted and then easily removed to access the required connections. Plugs are also designed to ensure that all pins are contacting their proper connections.

Sockets

Sockets are designed to connect and secure components where the pins are already connected. Sockets are used in high-density applications, along with 16-line pins that allow for more intricate controlled circuits. The 2713748 application field and working principle of sockets is that they are designed to protect components from short circuits, voltage spikes, and other harmful conditions. They require minimal current to operate and come with several safety features to help protect components.

Connectors and sockets have evolved over time, providing more reliable connections and higher-power ratings. As they have become more reliable and cost-effective, more applications have been designed to utilize their advantages. For these reasons, sockets continue to be popular for many electrical designs including: LED lighting systems, robotics, gaming, and automotive.

Terminal blocks, with their headers, plugs, and sockets, have proven themselves to be a valuable interconnect solution for electrical systems. They are designed to create reliable connections that will provide enhanced continuity, safety, and protection to electrical components. The 2713748 application field and working principle of each type of terminal block are clear, and their value in providing reliable power connections has made them an invaluable component in many industrial designs.
