Terminal Blocks - Accessories

1872486 application field and working principle of terminal blocks is the application field and working principle of terminal blocks, a kind of cable connection devices. Terminal blocks are usually used to provide electrical connection between different electronic equipment or between power and electronic equipment, so as to realize the combination of different electronic equipment to form various systems, greatly reduce wiring difficult and time-consuming.

Terminal blocks can be divided into double connection terminal blocks, multi-participant terminal blocks, ground terminal blocks, screw terminal blocks and rod terminal blocks according to their different forms. Among them, the most widely used is the screw terminal block, which is mainly composed of block body, screw nut and conductive, insulation and separation components. It has the advantages of good insulation performance, convenient installation and good contact.

The working principle of screw terminal blocks is through the screw nut combined with the conductive materials inside to achieve the connection of the electrical circuit. The screw nut has a certain pre-torque, and the inner spring is used to ensure the pressing force and contact performance of the screw. The connection between the wires and the screw terminal blocks is mainly through the cutting and crimping of the wires on the terminal blocks, and through the spring pressure of the screw nut to press the insulation of the wires. In order to facilitate the replacement of the wires and ensure the safety of the wiring, the screws on the terminal blocks are usually no more than 1.5mm. In addition, besides connecting the wires between the terminal blocks, the plug-in connection and plug-in connection between the wires of the terminal blocks can also be selected.

Terminal blocks are widely used in communication switches, electrical boxes, UPS systems, power supplies, cooling systems and other industries. For example, for data switches, terminal blocks are used to connect different cables for communication. For an electrical box, a terminal block is used to connect the wires between the power line, so that the electrical box can ensure continuous power supply for the internal electrical equipment.

In summary, terminal blocks - accessories 1872486 application fields and working principles mainly includes the forms of terminal blocks, the composition of the screw terminal block, the working principle, and the application of the terminal block in different industries. It has the advantages of convenient installation and good contact, which can be applied in communication switches, electrical boxes, UPS systems, power supplies, cooling systems and other industries.
