Terminal Blocks – Headers, Plugs and Sockets are devices used to fasten, transmit and eliminate electrical signals. Also known as Termination Blocks, the main function of this device is to terminate and/or connect electrical wires. They are used to connect and secure wires that are removed or replaced often, such as in power distribution panels, motor control, automobiles, and medical and other equipment. Terminal Blocks – Headers, Plugs and Sockets come in various sizes, materials and configurations, suitable for many applications. The most commonly available products are those manufactured to MIL-STD-16734/4-0000 specification.

MIL-STD-16734/4-0000 is a widely used standard specification for Terminal Blocks – Headers, Plugs and Sockets. It describes the design features, wiring and mechanical construction, material, and testing requirements of such devices. The document stresses electrical safety and appliance integrity, environmental concerns and compatibility with other personnel safety/shock prevention equipment.

Typical products specified under the MIL-STD-16734/4-0000 specification include both Headers and Plugs, also known as Pin Headers and Sockets or Female Connectors. Header and Plug devices are used for a wide variety of electrical applications, including socket receptacles and headers, circuit board connectors and terminal strips, and power relays and motor control systems. Both Headers and Plugs employ multiple wires, and are available in a variety of configurations and sizes to meet the needs of most applications.

Headers and Plugs are designed to mate with each other to form a secure, low-impedance connection. Headers are typically mounted on a circuit board or other device, while Plugs are normally secured to wiring harnesses or cables, allowing the user to quickly and easily connect and disconnect the circuit, making it convenient to access the connection during maintenance or troubleshooting. Headers and Plugs employ various contact designs, including blades, prongs, and tabs to ensure good connection. The contact force of Headers and Plugs is typically maintained by a spring-biased mechanism.

For high temperature or high-vibration applications, the contact spring force is designed to be higher so that the connections do not become undone accidentally. For low voltage and low current applications, the contact force is designed to be low so that it is easier to plug and unplug the connection.

Terminal Blocks – Headers, Plugs and Sockets are ideal for applications in a variety of industries including medical, military, industrial, automotive, and consumer electronics. Their use enables connection of both delicate and large signal lines, making them indispensible for many applications. The MIL-STD-16734/4-0000 specification is just the starting point for utilizing this reliable and flexible technology.
