Functions and application fields of terminal blocks

Nowadays, in many electrical equipment, it is often necessary to connect terminal blocks. After connecting, the terminal blocks can play the role of transmission. Especially in the electrical field, terminal blocks are particularly important, which can realize long-distance connection!

Function of terminal blocks
Terminal block is actually a kind of connector, which is used to facilitate the connection of wires. It is actually a piece of metal enclosed in insulating plastic, with holes at both ends, which can be inserted into wires. With the development of the electronic industry, the use of terminal blocks has become more and more extensive. At present, they are mainly used in power control, equipment control, automatic control, security control, instrumentation and other industries. If the terminal is not used before, the copper wire is directly connected to the screw. If there is a terminal, it will be much safer and won't fall off.

Its tail is also insulated.
There are holes at both ends of the terminal block for inserting wires, and screws for fastening or loosening. For example, two wires sometimes need to be connected and sometimes need to be disconnected. At this time, they can be connected with terminals and can be disconnected at any time, without welding or winding them together, which is very convenient and fast. It is also suitable for the interconnection of a large number of wires. In the electric power industry, there are special terminal blocks and terminal boxes, which are full of terminal blocks, single-layer, double-layer, current, voltage, common, and disconnectable. A certain crimping area is to ensure reliable contact and sufficient current.

Application field of terminal blocks
The terminal block is a basic accessory. Its function is extended from screws and screws to be applied in the field of electrical connection and control. It has the requirements of firmness, safety, beauty and speed. With the progress of society and the increase of labor costs, the requirements for terminal blocks are also higher and higher. Its main manifestations are as follows:
1) Control box industry: control integrated systems such as electrical equipment plants, power protection, power generation control sets, power control boxes, etc. have box, switch, fuse, metering device, instrument, signal control and other control components, and control lines with large current mainly use rail-type terminals;
2) Components and accessories, power consumption of instruments, controllers, relays, meters, switch control systems and other components in the control cabinet, and input and output terminals for control functions, as well as independent lighting, power supply, motors, instruments and meters, automation equipment control, and other power consumption and control functions.
Terminal block is a kind of accessory product used to realize electrical connection, which is divided into the category of connector in industry. With the increasingly high degree of industrial automation and the increasingly strict requirements of industrial control, the consumption of terminal blocks has gradually increased. With the development of the electronic industry, the application fields of terminal blocks are more and more extensive, and the types are also more and more.
