Terminal blocks, headers, plugs, and sockets, have different, yet related, applications and working principles. The 1779475 series, from TE for example, is a useful product to understand the different functions of each component in the context of the larger electrical system.Terminal blocks are used for connecting multiple wires which are electrically isolated from one another. A terminal block consists of individual screw terminals and a common busbar at the base. Wires are connected to the busbar and the individual screws hold the conductors. Different sizes of terminal blocks exist, allowing for different wire sizes and varying applications. Wire material and the type of insulation are taken into consideration when determining which size of terminal block to use.Sockets and plugs, in the context of 1779475, are typically used for applications which require a semi-permanent connection to be made. Plugs are inserted into a socket and secured with screwed connections. The pins in a plug are electrically isolated from one another, meaning that individual conductors are connected. Plugs can be removed and re-inserted for applications that need flexibility or wherever parts of a circuit need to be easily disconnected and reconnected.Headers are generally used for applications involving printed circuit boards. Headers have multiple heat-set sockets for pins and are commonly used for protocol-compliant electrical connections. A connector is inserted into the header, and the pins of the connector come into contact with the sockets in the header, creating a secure and reliable connection. Headers are often used as jumpers between pins on electronic boards or for connecting multiple wires in a circuit.To sum up, the 1779475 series products from TE provide a range of components for various electrical applications. Each component, terminal blocks, headers, plugs, and sockets, have their own purpose and unique working principles. Terminal blocks provide the ability to connect multiple wires which are isolated from each other, while plugs and sockets offer semi-permanent connections for flexible electrical connections. Finally, headers are used for connecting pins on printed circuit boards or for connecting multiple travel wires in a circuit.
