Terminal Blocks - Wire to Board

1720 Terminal Block and Working Principle

The 1720 terminal block is a style of wire-to-board connector designed for use in automotive, appliance, and industrial applications. With an array of electrical contacts and a wide variety of contact material and design, these blocks can provide a wide range of utility in various applications.

A 1720 terminal block is designed for a variety of applications, including vehicle and appliance electrical wiring, industrial process control wiring, and telecom/data cabling. It is intended for use with rigid, solid conductor wires and bare stranded wires in a single conductor configuration. In some applications, it is also suitable for use with other types of wires, such as twin-axial cables.

The 1720 terminal block is available with a variety of contact materials, termination styles, and contact configurations. Common contact materials used in 1720 terminal blocks include brass, phosphor bronze, tin copper, and beryllium copper. Termination styles include nail points, screw points, through holes, and quick release pins. More advanced blocks feature contact configurations with multiple pairs, dual-pole, and terminal connections. These blocks are also available with a variety of different ratings, including up to 400A and 600V.

The operation of a 1720 terminal block is based on a simple principle – when two contacts of different polarity are touched together, the electrical current flows through the connection, from the positive pole to the negative pole. This creates an electrical connection that can then be used for power, control, safety, or communications. The contact materials, shape, and size of the contacts determine the maximum voltage that can be applied and the electrical current that can be supplied.

The most common applications for 1720 terminal blocks include vehicle and appliance wiring, process control wiring, and telecom/data cabling. Vehicle wiring applications are used to connect the various power supplies and electrical devices in a car, such as headlights, horn, starter motor, and air conditioning unit. The blocks are also used in appliance wiring applications, such as washing machines, refrigerators, and TVs, to link the power supply to the electrical devices. Process control wiring applications use the blocks to connect the electrical supply to the various motor and control systems in a manufacturing line. Finally, the blocks are often used in telecom/data cabling applications, such as connecting computers to modems or network hubs.

To ensure a quality connection and a safe operation, it is important to check the contact materials and contact configuration before using 1720 terminal blocks. Additionally, the correct installation of the block is essential; proper torque requirements should be followed to ensure a secure connection. Proper maintenance and inspection of the blocks should also be carried out regularly to ensure a safe and reliable operation.

The 1720 terminal block is suitable for a variety of automotive, appliance, and industrial applications. With its high current carrying capacity, these blocks offer the potential for high reliability and a long service life. With the correct selection of contact materials, contact configuration, and installation process, the blocks can provide a reliable and safe connection for any application.
