EC121000B000G, a type of terminal block, improve the connection between wire and circuit board. As reliable components, it is widely used in many areas and now I would explain what the application field and working principle are.

Application

EC121000B000G is widely adopted by telecom, industrial automation, automotives and new energy. Let\'s take an example from telecom. When people want to make a call, they need a switchboard, which requires a large number of terminal blocks to ensure the voice and data signals correctly transmitted. Without the terminal blocks, the electric signal can be easily interrupted due to cable wriggling, leading to a poor switchboard performance. Consequently, the terminal blocks here play a very important role. Regarding the industrial automation, there is also an example. Motor Starter terminals blocks, which are mainly used for motor control circuits, are essential for a safe and reliable running process. The motor starter helps to protect motors from overloads and short-circuits and connect the motor with the control panel.

Working Principle

When an EC121000B000G is installed, the wire is first applied into it and then the metal screws, which are the main conducting element, fasten the wire tightly by pressing it against the contacts while the screw is tightened . The tightening of the screws results in an increase of the conductor resistance, creating a high-pressure zone that ensures excellent conductivity. Additionally, an elastic material, which helps to absorb vibration and shock, is also packaged with the metal screws and this material helps to further guarantee a secure connection between the wire and metal screws. Besides, there are two types of EC121000B000G: vertical and horizontal. A vertical terminal block has an insertion hole and a screw hole on the same side, allowing it to easily align and attach to other components. The horizontal terminal block has insertion hole and screws holes on opposite sides, and it is suitable for installation of larger wires.

Conclusion

EC121000B000G is an important part of many applications, especially in telecom and industrial automation. It has a wide variety of uses, from connecting wires to circuit boards to protecting motors from overloads and short-circuits. Its working principle, either vertical or horizontal, is based on screws and elastic materials that guarantee a secure connection between the wire and metal screws. EC121000B000G is an important component that helps many industries run better and more safely.
