Terminal Blocks - Headers, Plugs and SocketsTerminal blocks are defined as detachable electrical interfaces which are used to connect to two different electrical devices together. They provide the electrical connectivity of different electrical circuits or the joining of electrical wires. Terminal blocks offer the flexibility and convenience of easy assembly and are available in various sizes, shapes and types.There are three main types of terminal blocks: headers, plugs and sockets. HeadersHeaders are also known as splice blocks or double-level terminal block. They provide a space for splicing two or more wires together. They have a double layer of conductors on their base, allowing multiple connections. Headers can be further classified into two sub-categories:• Non-insulated headers - These are made of plastic and are offered in single or dual level configurations. They are generally used for low current applications like signal and sensor lines.• Insulated headers - Insulated headers provide a higher level of insulation against electrical shock. They are offered in single and double level configurations and can be used in high current applications.PlugsPlugs are used to connect electrical wires to terminal blocks. They are available in various types and sizes and are suitable for different voltage and current levels. The advantages of using plugs include easy installation, no need to strip or tin the wires, and a low contact resistance.SocketsSockets are used to connect the terminal block to another electrical device. They are generally made of metal and are offered in a variety of configurations. Sockets are available in both single and double level configurations and can handle high current levels.The 1778845 application field and working principle of terminal blocks depends greatly on the type of terminal blocks used and the application it is used for. Headers are generally used for splicing different electrical wires together. Plugs are used to link an electrical wire to a terminal block and sockets are used to link the terminal block to another electrical device. For a double-level header, the lower level provides the electrical connection to the wire while the upper level provides the electrical connection to the other terminal block. Each level has a set of contacts that must be inserted into the block to complete the connection.For a single-level plug, the plug is inserted into the female contacts of the terminal block and is secured with a lock, which ensures a good electrical connection. For a double-level plug, the upper level is used to provide the electrical connection to the other terminal block and the lower level is used to provide the electrical connection to the wire.For a single-level socket, the socket is inserted into the female contacts of the terminal block and is secured with a lock. The socket provides the electrical connection to the other terminal block. For a double-level socket, the upper level is used to provide the electrical connection to the other terminal block and the lower level is used to provide the electrical connection to the wire.Terminal blocks provide the electrical connectivity of different electrical circuits, and they are widely used in various industrial and commercial applications. They offer the flexibility and convenience of easy assembly and are available in various sizes, shapes, and types.
