Terminal Blocks - Headers, Plugs and Sockets are widely used in a variety of applications, especially in the electronic industry. The terminal blocks, also known as Link Blocks, are connective elements that link internal circuit paths to external wiring and external wiring to external equipment.

The most basic type of the terminal blocks are the Headers, plugs, and sockets. A header is a device that is inserted into a breadboard or an enclosure, and it usually contains terminals that are soldered onto a PCB. It’s purpose is to permit easy connection and disconnection of wires and equipment. It also provides an easy means to make and break electrical connections between the components. A plug is a connecting element that is placed on the end of the wire, and it has a variety of forms with different terminals and functions. A socket is a connecting element that is mounted onto the circuit board, and it is typically used to couple two separate devices.

The size, durability, and type of contacts in the headers, plugs, and sockets vary greatly depending on the application. For example, in the field of communication, they are usually composed of insulated plugs and sockets that provide reliable and secure connections. On the other hand, in industrial applications, headers are typically soldered directly onto the PCB, and the contacts are crimped onto the wires. The key to selecting the right headers, plugs, and sockets is to understand the application and requirements of the environment in which they will be used.

The working principle of headers, plugs, and sockets is based on the principle of electrical conduction. In order for an electrical current to flow through a circuit, a voltage potential must exist between two points. Therefore, the header, plug, and socket provide a connecting point between two electrical components, allowing the current to flow between them. This is achieved by having metal contacts that allow an electrical current to flow when two components are connected.

Headers, plugs, and sockets are used in a wide range of applications and provide reliable and secure connections. They are available in a variety of sizes and types, and they are designed to meet the needs of different applications and environments. The most important factor in selecting the right headers, plugs, and sockets is to understand the application and environment requirements.
