Application Field and Working Principle
Terminal Blocks - Headers, Plugs and Sockets
Terminal blocks are among the most versatile of all electrical connection components, bridging the gap between various connectors and terminals used in many industrial, medical and automotive applications. This article provides an overview of the application field of terminal blocks, as well as their working principle.
What are Terminal Blocks?
Terminal blocks are electrical connections that join two electrical circuits. Despite their name, terminal blocks are neither made up of a single solid material, nor do they contain any type of terminal for wires. Instead, they are composed of several metal pins, usually made from stainless steel or brass, and these pins are used to establish electrical contact between the two circuits. The pins are usually secured by soldering or a screws and nuts dependency.
Terminal blocks have become increasingly popular over the past few decades for a number of reasons. The wide range of pin configurations available make them suitable for use in many different applications. Furthermore, they are also more resistant to environmental factors such as temperature and moisture, due to their use of more durable materials such as brass or stainless steel.
Applications of Terminal Blocks
Terminal blocks are widely used in industrial, medical, and automotive applications. In the industrial sector, they are used to provide efficient and reliable connections between various components in machines and process control systems. They are also popular in medical device applications, as they are able to withstand sterilization and other demanding conditions.
Additionally, terminal blocks are also used in automotive applications, since they are able to not only endure vibration and shock, but also provide a high level of electrically secure connections. Their applications range from the distribution of power in automated production lines, to the maintenance of electrical systems in cars.
Working Principle of Terminal Blocks
Terminal blocks are composed of two parts; the base and the wiring. The base is a strip of dielectric insulation material which contains the metal pins. The wiring is a piece of conductor which is attached to the pins and inserted into the insulation material. As the conductor is inserted into the insulation material, it creates an electrical connection between the two ends of the conductor, which allows for the transfer of energy between the two circuits.
When the wiring is inserted into the insulation material, the metal pins must also be secured. This is usually done with screws, which are tightened to create a strong mechanical bond between the wiring and the pins. Additionally, the pins can also be secured with solder, which forms a stronger bond than a simple mechanical connection.
Terminal blocks are also used to form more complex electrical connections. Multiple pins can be connected in series or parallel in order to provide a more powerful electrical current or increase the amount of current available. This is sometimes referred to as "cascading," and it allows for the addition of more pins while maintaining the same amount of space.
Conclusion
Terminal blocks are essential components in many industrial, medical and automotive applications, allowing for efficient and reliable energy transfer between two separate circuits. Their wide range of pin configurations and ability to endure a variety harsh conditions make them an ideal choice for a variety of applications. Additionally, their ability to combine multiple pins in a series or parallel connection make them suitable for more complex electrical connections.
