Terminal blocks, also known as headers, plugs and sockets, are the most common connection methods for the wiring of electrical equipment. They are widely used in industrial control equipment, communication and industrial automation systems, circuit boards and plug-in connectors for computers and other electronic systems. 1948040000 application field and working principle.

Terminal blocks consist of two parts: a terminal block body and a plug-in device. The terminal block body is a conductor and insulator with a certain current and voltage rating, and it is composed of a contact, a bridge, an insulating material and supporting components. Its most commonly used form is a metal rail with multiple terminals arranged in a line. Each terminal is a single socket with a certain current carrying capacity and voltage resistant performance. The plug-in device includes an insulation panel, a block plug connector and a bridge contact plug connector.

The working principles of terminal blocks are based on two elements: electrical connection and mechanical connection. The electrical connection is based on the pin contact between the two contacts, which completes the electrical connection. The effect of the mechanical connection is to fix the block conductor to the conductor to achieve the purpose of short connection and parallel connection. For example, high-voltage and low-voltage terminals are used to prevent reverse connection, and parallel connection terminals are used to protect the coil from overheating.

Terminal blocks are used in many different applications, from the simple wiring of high-voltage and low-voltage lines to complex communication and computing systems. In the industrial production line, they are used to ensure a reliable, secure connection between motors, sensors, actuators, servo controllers, and other components. For example, high-voltage AC terminal blocks are widely used in the control of AC motors, and low-voltage DC terminal blocks are used in the wiring of communication systems. In addition, terminal blocks are essential for the production of electronic equipment, such as computers, cell phones, and cameras.

Terminal blocks are available in a variety of styles, shapes, and sizes, from standard through-hole terminal blocks to modular blocks that are configured and assembled to meet specific application requirements. Different types of connections are also available, from screw-on posts to push-in lugs. The selection of the right type of terminal blocks for the application is essential for ensuring maximum performance.

Terminal blocks can be used to replace permanent wiring connections, as well as to provide a simple and cost-effective way to wire and rewire electrical equipment. They are not only used in industrial settings, but are also becoming increasingly popular in home automation and entertainment systems. Terminal blocks are the ideal solution for connecting various electrical systems and electrical equipment.
