Terminal blocks, also known as terminal boards, are used for load and power distribution, as well as for interconnection, signal transference, signal isolation and low voltage radio frequency control. They are common in industrial, commercial and residential control systems. Terminal blocks are typically used to group several wires into one connection point. They are available in a variety of sizes and configurations.

1902822 Application Field and Working Principle

The usage fields of 1902822 terminal blocks mainly include laboratories, control cabinets, machines and electrical devices, boards, boxes, panels, control cases, wires termination, etc. It is a type of signal and power connection terminal block. The 1902822 terminal blocks are designed for use up to 6A, 400Vac and 4mm2 wire and are suitable for a broad range of applications from small control panels and machine control systems to large industrial machinery and equipment applications. It features easy, safe and reliable wiring.

The main structure of 1902822 terminal blocks is a contact unit and a clamp, which is connected by an assembly and a plate. 1902822 terminal blocks have many advantages. They is easy to install, remove or reorganize wires. With self-locking function, it can greatly reduce the possibility of plug-in errors. Moreover, it also offers a large contact surface, reducing contact resistance and increasing current rating. The snap-on spring design on the release lever ensures it won’t be accidentally moved, providing a secure connection.

The working principle of the 1902822 terminal blocks is as follows: With few components and no wires passing through, it can create a stable connection fitting for high current using a spring-locking mechanism. The spring-locking mechanism is at the core of the working principle. When the terminal blocks are connected and disconnected, its clamping mechanism allows the contact to open when pressure is applied and closed when pressure is removed. This ensures a secure and reliable connection, so the current flows normally.

The 1902822 terminal blocks also feature a protection mechanism. It is designed with a screw that applies pressure to pressing plates on both sides of the spring. The pressing plates then hold the contact points on both sides of the spring in place. This ensures that the contact remains in its original state, preventing it from loosening or damaging, and guarantees continual current flow.

To sum up, the 1902822 terminal blocks is a secure, safe and reliable power and signal connection terminal blocks. With its simple and reliable structure, easy installation and operation, it is much favored by the current customers.
