Terminal Blocks - Contacts

Terminal blocks are electrical connectors used to securely connect electrical wires. They can be used for both making connections between two wires and for connecting multiple wires together through a single connector. They are available in a variety of sizes, shapes and styles, making them a versatile and economical solution for many electrical projects.

Terminal blocks consist of two main parts, the contact and the block. The contact is the part that contacts the wires and the block is the outer shell that holds the contact in place. The contact is typically made from either metal or plastic and is designed to conduct electricity from one wire to the other. The block is generally made from a strong plastic, such as nylon, that is strong enough to hold the contact securely.

The contacts on a terminal block can be of either a screw-type or a push-in type. Screw-type contacts are fastened to the wire by using a screw, which securely holds the wire in place. Push-in connections require no tools and simply push straight in to the contact, although extra care should be taken to ensure the wire is securely held in place. Push-in connections are ideal for low-voltage applications where the user is not experienced with using screw-type connections.

Terminal block connections are appreciated for their versatility, reliability and cost-effectiveness. They are used in a variety of industrial, consumer and commercial applications, including lighting, automation systems, home appliances, security systems and more. They can be used in high-power and high-voltage devices, as well as low-power and low-voltage devices.

The working principle of a terminal block relies on the simple concept of conduction. As electricity passes through the contact, it creates an electrical field around it, which enables the electricity to flow through the contact and the block. This electricity then flows through the attached wires and to the desired destination, completing the connection.

Terminal blocks are a useful and reliable connection method that has been around for more than a century. They continue to be used as the go-to connection option in many applications due to their cost-effectiveness, versatility and durability. With the right terminal block for the job, anyone can easily set up and maintain an electrical connection quickly and easily.
