Wire Terminal (Spring)

Terminal springs, also known as spring terminals, are critical components in electrical connections. Serving as an essential medium for connecting wires to devices, terminal springs are widely used in various electrical equipment, electronic devices, and industrial control systems, ensuring reliable transmission of current between different circuits. This article will explore the functions, working principles, types, and importance of terminal springs in electrical connections.

Types of wire terminal

Single-piece terminal springs: These springs are made from a single piece of metal formed into a spring structure through bending. They are the most common type of terminal spring and are typically used for low-current connections.

Multi-piece terminal springs: Composed of multiple metal pieces, these springs offer greater elasticity and a larger contact area, making them suitable for high-current and high-vibration environments.

Crimp terminal springs: These springs secure the wire within the terminal using a crimping method, providing high mechanical strength and stability. They are commonly used in applications requiring highly reliable connections, such as in automotive or motor applications.

Spring-loaded terminal springs: These springs have an internal spring mechanism that automatically adjusts the pressure to accommodate wires of different sizes. They often feature a self-locking function, making installation quick and easy.
