Terminal Blocks - Headers, Plugs and Sockets

Application of 1942370000 terminal blocks, plugs, sockets and headers helps in addressing different types of electrical connections. This product line includes several items such as Headers (socket strips and plug strips), Plugs, Sockets and Terminal Blocks. While the use of these items can be categorized based on the type of device they are used with (such as telephone systems, automotive, motors, etc.), it is often helpful to look at their general use and working principles as well.

Headers

Headers (also known as plug strips or socket strips) are often applied as bridge-type connectors. They allow for single wiring harness and cable assemblies to be attached and then routed using several different terminals. Headers are designed to be used with wider cable gauges and can often allow for multiple plugs to be inserted. They are usually employed in both flat cables and round cables, with round cables often being used to provide better strain relief.

Plugs

Plugs, also known as male connector units, are used to connect the wiring harness or cable assembly to the header. They feature a socket that carries the electric current, while acting as a mechanical connector to hold the wires together. These plugs come in both male and female genders and can be designed in a wide variety of sizes and shapes.

Sockets

Sockets, also known as female connector units, are sometimes used in place of plugs. They have openings on both sides of the connector in which the wires will be inserted. By using appropriate wiring harnesses and cable assemblies, sockets can effectively be used as bridge-type connectors. Additionally, when two wires with different gauge sizes are present, it can be beneficial to use a socket instead of a header for better termination.

Terminal Blocks

Terminal blocks, also known as PCB terminals, are often used in combination with headers and other types of connectors when it is necessary to install multiple connections. They have a single pin that connects the power connection and the ground, and can easily be attached to the headers using a variety of tools. These tools either require a crimping force to ensure optimal contact, or they have self-releasing pressure that is easy to operate. Additionally, terminal blocks are much smaller than headers and are therefore ideal for smaller applications.

Working Principles

Headers, plugs, sockets and terminal blocks all employ basic electrical principles in order for them to effectively work. The fundamental rule, often called Ohm\'s law, states that the total voltage drop is equal to the current multiplied by the resistance. This law is important, as it implies that no current can flow unless the voltage is greater than the resistance. In using these items, this voltage must be maintained in order for the connection to function properly.

Additionally, when using terminal blocks, it is important to consider the amount of current that will be flowing through the connection. The terminal block is rated for a certain amount of amperage, and if this limit is exceeded, then the connection may become damaged or unstable. The size of the terminal block is also important to consider, as it must be able to adequately contain the amount of current that is being supplied.

Overall, headers, plugs, sockets and terminal blocks are essential items when constructing electrical connections. All of these items have different applications and employ basic electrical principles in order to operate properly. By following these guidelines, users can ensure that the connections are strong, reliable, and free from electrical issues.
