Terminal blocks are electrical devices used to connect two or more electrical circuits into one circuit. They provide an effective way to wire electrical applications, such as machines, control systems and lighting systems. There are several different types of terminal blocks, from basic plug and play models to more specialized systems that offer higher levels of control and connection points. The type of terminal block used is determined by the application and the amount of control required.

2904273 Application Field and Working Principle

Terminal blocks are widely used in various industries such as automotive, home appliance, electrical and electronic, medical equipment, communication, etc. They have a wide range of uses, such as in power distribution, signal connection, control, communication, and data transmission. In automotive, they are often used in the connection of the power supply module, the control circuit, the sensor signal acquisition circuit, and the motor control circuit.

The central part of terminal blocks is the modular terminal assembly, which usually has two types of module assembly components: wiring components and insulation components. The wiring components are responsible for electrically connecting the conductive terminal and providing the contact part for the electrical wiring. The insulating component is responsible for the insulation and protection of the electric core, so as to achieve the electrical insulation of each circuit. It also prevents the metal parts from being short-circuited.

Terminal blocks have a large variety of terminal styles and installation methods. They are usually integrated with relay sockets, indicating lamps, terminals, DIN rails, plugs, fuses, and other components. According to the shape of the end face, it can be divided into two categories: punching type and finger press type; according to the installation method, it can be divided into plug-in type and rail mounting type, both of which have 3 and 6 row varieties.

The working principle of terminal blocks is to connect multiple electric circuits by the connection wiring block and the terminal block. Each electric circuit is equipped with a separate terminal block, and the two terminal blocks are connected by a connector. The connector can be made of a variety of material such as metal, plastic, PVC and other materials, which can be connected to the terminal block through a variety of methods such as screw, bolt and rivet. The terminal blocks can be made with a variety of insulating materials. The most common is nylon, plastic, or ceramic.
