A PCB Spring Terminal Block is an electrical connector used to securely connect wires to a printed circuit board (PCB) using a spring-clamp mechanism instead of traditional screws.

Key Features:

• Tool-Free Connection: Uses a built-in spring to hold the wire, allowing for quick and easy wire insertion and removal without a screwdriver.

• Vibration-Resistant: The spring mechanism maintains constant contact pressure, ensuring a reliable connection even under vibration or thermal expansion.

• Compact Design: Ideal for tight spaces on PCBs in compact electronic devices.

• Reusability: Wires can be reinserted multiple times without damaging the terminal block.

How It Works:

1. You press or push a button or tab to open the internal spring.

2. Insert the stripped wire into the terminal.

3. Release the button—spring clamps onto the wire to make an electrical connection.  

Applications:

1. Industrial control systems

2. Power supplies

3. Building automation

4. LED drivers

5. Smart home devices

6. IoT and embedded systems
