Terminal Blocks - Headers, Plugs and Sockets

1089380000 is a generic catalog number for a series of related electrical components. Specifically, 1089380000 is used to describe what is known as a terminal block, header, plug, and socket. These components are essential to electrical wiring and have a wide range of applications.

Application

Terminal blocks can be found in numerous places in modern machines. In power supplies, terminal blocks are used as a safe connection point for line voltages, allowing the electricity to be distributed and managed within a product. Electronic control equipment that runs on low voltage may also use terminal blocks and headers. In these applications, either wire-to-board, board-to-board, or wire-to-wire connections may be created. The smaller plug and socket connection systems achieve reliable connections at a fraction of the size of a terminal block.

Terminal blocks also find use in lightning protection systems, busbars, and low voltage DC applications. In busbars, terminal blocks are used as a connector between different cables or branches in the electrical supply network. In professional audio and video, terminal blocks are used to create connections between amplifiers, speakers, etc. Terminal blocks are also used in broadcasting, telecommunications, industrial plants, and automated control systems.

Working Principle

Terminal blocks, headers, plugs, and sockets function as a connection point between two separate points of an electrical circuit. Terminal blocks provide a safe place to link together different incoming and outgoing wires. The wires are then secured to the terminal block utilizing one or more of the available connection methods, such as screws or springs.

Headers are electrical components used to connect two wire harnesses or boards together. They utilize either screws and posts or PCB pins. Plugs and sockets are smaller devices that serve as a fast and secure connection point between two smaller pieces of a circuit. They are generally smaller than terminal blocks and are used to join two wires together without the need for any further connections.

No matter the application, a terminal block, header, plug, and socket serves as a reliable connection point between two parts of an electrical circuit. Its purpose is not to create an electrical connection between two wires, but to provide a secure connection point that allows for a reliable electrical connection to be easily achieved.
