Terminal Blocks - Headers, Plugs and Sockets – Application Field and Working PrincipleTerminal blocks are widely used in electrical and electronic engineering field for connecting two or more electrical circuits securely and easily. They are highly standardized connectors which facilitate wiring and cable management for a substantial savings in time and effort.Terminal blocks are classified into three groups, depending on their usage: Headers, Plugs and Sockets. All types of terminal blocks offer the same basic features, but each type has its own advantages and disadvantages.HeadersHeader terminal blocks are used when a group of wires need to be run to a single point. They are typically 2 to 24 contacts per row and can often be held in an array for higher current applications. The contacts can be spring loaded or soldered, depending on the application. The contacts normally accept stranded wire and this makes it easier to crimp compared to solid wire. They are ideal for low voltage, low current applications.The header terminal blocks are available in PCB mount and chassis mount varieties. The header can be flat or stepped depending on the amount of current that needs to flow through it. The stepped headers are designed to allow multiple sets of pins to fit into the same space and will have a higher current rating than the flat versions.The header terminal blocks are also available in different types of materials including, phenolic, plastic and metal. The metal versions are the most robust of the three and are suitable for higher current applications. Plastic versions are often used with general purpose applications.PlugsPlug terminal blocks are used to connect two circuits together. They are usually available with 3 to 12 contacts on the same row and are either spring loaded or soldered. The contacts normally accept stranded wire which is easier to crimp than solid wire. They are ideal for low voltage, low current applications.The plug terminal blocks are available in a range of materials including, plastic, phenolic and metal. The phenolic version is suitable for general purpose applications. The plastic versions are available in a variety of colors which can be used to differentiate between different wires. The metal versions are usually used for higher current applications.The plug terminal blocks also have a variety of configurations including, swivel type, angled type and axle type. The swivel type has the most versatile range of currents that can be accepted due to the multiple contact points which are in the shape of a cup. The angled type is used for connecting two circuits that are in different positions. The axle type is used for piezo electric actuators and is often used in robotic applications.SocketsSocket terminal blocks are used to provide a connection from a moving circuit to a stationary circuit. They are usually 2 to 16 contacts in a row and can often be stacked to increase current. The contacts normally accept stranded wire which is easier to crimp than solid wire. They are ideal for low voltage, low current applications.The socket terminal blocks are available in a variety of materials including, plastic, phenolic and metal. The phenolic version is suitable for general purpose applications. The plastic versions are available in a variety of colors which can be used to differentiate between different wires. The metal versions are usually used for higher current applications.The socket terminal blocks also have a variety of configurations including, high current, low current, board mounted and chassis mounted. The high current versions are more robust and are suitable for higher current applications. The low current versions are often used in general purpose applications. The board mounted versions are usually used when space is limited. The chassis mounted versions are used for large power applications.ConclusionIn conclusion, terminal blocks are highly versatile connectors that are used for connecting two or more electrical circuits in a safe and secure manner. The three types of terminal blocks – Headers, Plugs and Sockets – all have the same basic features but each type has its own advantages and disadvantages. They are available in a variety of materials and configurations, depending on the application.
