IntroductionThe 1771020 terminal block, sometimes referred to simply as a European Terminal Block or a Euro-style terminal block, is a type of industrial grade electrical connection system commonly used in electronic systems and equipment. The terminal block provides a secure electrical interface between a wire and an electronic component or circuit board. The design enables a easy and wireless connection that can be quickly and easily separated. Applications1771020 terminal blocks are available for a huge variety of applications, including wire-to-board, wire-to-board hot swap, and wire-to-wire. Common applications include wiring automotive electronics, industrial systems, computers and peripherals, renewable power equipment, and white goods. Wire-to-board applications are where the terminal block connects the wire to a board. These terminal blocks are designed to give a secure electrical connection between the wire and circuit board. This type of terminal block offers versatility in a variety of applications.Wire-to-board hot swap applications are where the board is inserted and removed from a unit without losing the electrical connection with the terminal block. This design is ideal in applications where components often need to be quickly disconnected without the need for tools. Wire-to-wire terminal blocks are also available for connecting multiple wires in a single connection. Design FeaturesThe 1771020 terminal block offers several design features, such as a one-piece, two-piece, or three-piece design with a variety of termination options. It is designed for a wide range of current, voltage, and temperature ratings, with terminal blocks capable of carrying up to 10A. The terminal block has a double layer terminal design which provides superior insulation and strain relief. The terminal block also has a low profile design which makes it easier to install in tight spaces. Installation & AssemblyThe device is easily installed by simply inserting it into a gland seal connector. The glands seal connectors are precise, reliable, and are designed to accept multiple types of wires, such as stranded and solid. The terminal block can also be snapped into place using a variety of mounting configurations. Once assembled, the terminal block is secured with a spring-action clamp which is tightened with a screwdriver or hex nut.Working PrincipleThe 1771020 terminal block works with an electrical connection between two contacts. One of the contacts is the wire, which is inserted into the wire connector and made into electrical contact with the terminal block. The other contact is the circuit board, which is connected to the board connector. When the wire and board connector are securely held in place and the spring-action clamp is tightened, an electrical connection is created. This connection can be quickly disconnected as needed by loosening the clamp. ConclusionIn conclusion, the 1771020 terminal block is an industrial grade electrical connection system that is popular for a variety of applications, such as wire-to-board, wire-to-board hot swap, and wire-to-wire. The device is designed with features such as double layer terminal design and low profile for easy installation in tight spaces. The device creates an electrical connection between two contacts, the wire and the board connector, which can be quickly disconnected by loosening the spring-action clamp.
