Terminal Blocks - Headers, Plugs and SocketsTerminal blocks are mechanical components that are used to electrically interconnect various components in an electronics design. These components are used in almost every electronics design and are indispensable components for wiring, power, control and communications. Basically, terminal blocks are in the form of blocks electrically connected by means of pins or screws, and these terminal connection components can be called headers, plugs, and sockets. These components are often referred to simply as “terminal blocks” and in certain applications, they can also be referred to as connector blocks or relay blocks.Terminal Blocks – HeadersThe headers of terminal blocks are designed to provide terminals for the connection of other devices or components. Headers are formed by a series of conductive pins that are “guarded” by barriers on either side, and are typically either rigidly mounted to a panel or printed circuit board or are designed to be mounted to a post, a ribbon cable, or other such devices. In its most rudimentary form, a header will use two or more pins to form a bare wire connection, but there are also male headers that are used to form connections with female connectors. Headers can also range in size, pitch, and number of pins, which allows for a level of adaptability to any specific application.Terminal Blocks – PlugsPlugs are the components that connect to the header pins from a terminal block. Typically, plugs used in terminal block applications are either male connectors, like jumper and ribbon cables, or female connectors, like IDC terminals. These plugs are supplied with a variety of types and numbers of pins or contacts, and they can also be supplied in a variety of shapes and sizes. The main job of the plug used in electronic terminal block applications is to provide a secure connection, and these plugs will also often provide additional features, such as strain relief and EMI/RFI shielding.Terminal Blocks – SocketsThe sockets used in the terminal block application are the receptacles for the plugs, and they generally have two or more clearance holes for the mating plug. In addition, they also typically provide grounding, EMI/RFI shielding and strain relief functions. These sockets are also generally made from plastic and they can be designed to accept a wide range of plugs. The contacts on the sockets are either brass-plated steel or gold plated, which prevents corrosion and maintains contact accuracy over long periods of time.ConclusionTerminal blocks are an indispensable component in almost every electronic design, and they are formed from a combination of headers, plugs, and sockets. Headers provide the terminals for connection to other components, plugs form the connection the headers, and sockets provide the receptacle for the plugs to form the secure connection. These components come in a wide range of sizes and shapes, which allows them to adapt to almost any electronic application.
