1. Extremely high wiring efficiency and speed
This is the most intuitive advantage. Traditional screw terminals require at least three steps of loosening the screw, inserting the wire, and then tightening the screw again.
One plug is enough ": For quick terminals, simply use a screwdriver to push the operating hole to the bottom, insert the stripped wire, and then pull out the screwdriver to complete the connection. Some even require no tools and can be directly inserted (suitable for flexible cords or small wire diameters).
Save a lot of time: In scenarios with a large number of cables such as large-scale production, distribution box installation, or smart home panel wiring, this efficiency improvement is revolutionary and can save up to 70% of wiring time.
2. Reliable connection, resistant to vibration and looseness
Constant contact pressure: The quick terminal has a high-quality spring plate (usually made of high-quality stainless steel) inside, which can apply a constant and continuous pressure to the wire. This pressure will not weaken due to thermal expansion, contraction, or slight vibration.
Superior to screw connections: Screw connections may become loose in long-term vibration environments, leading to increased contact resistance, heating, and even accidents. And the elasticity of the spring can compensate for this change, maintaining a long-lasting and reliable connection, which is very suitable for vibration environments such as rail transit and mechanical equipment.
3. Easy to operate, reducing human errors
No torque control required: Screwing requires experience, too little force may result in poor contact, and too much force may crush the wire core or damage the terminal. The quick terminal eliminates this problem, as long as the wire is plugged in place, the spring will provide just the right amount of pressure.
Unified wiring quality: Regardless of the operator's experience, consistent and high-quality connections can be achieved, reducing quality fluctuations caused by individual technical differences.
4. Space saving and compact design
Higher wiring density: As there is no need to reserve a large amount of rotation space for screwdriver operation, fast terminals can usually be designed narrower and more compact. This allows for more points to be arranged in equally sized terminal blocks or distribution boxes, making it very suitable for modern control cabinets and distribution boxes with limited space.
5. Easy to inspect and maintain
Intuitive testing holes: The vast majority of fast terminals are equipped with specialized testing holes, which can be used to measure voltage and current with multimeter probes inserted without disconnecting, greatly facilitating circuit diagnosis and system debugging.
Easy to disassemble: Although insertion is simple, disassembly is not complicated either. Simply insert the screwdriver into the operating hole again and push it to the bottom to release the wire, and then pull it out. This makes line modification and maintenance very convenient.
6. Minimal damage to wires
Uniform clamping force: The spring plate provides a surface contact pressure that acts uniformly around the wire. And screw terminals are pressure points, and sharp screw edges can easily cut or break small copper wires, especially when using multi strand flexible wires. Fast terminals can better protect the integrity of wires.
7. Comprehensive cost reduction
Although the cost of a single quick terminal may be slightly higher than traditional screw terminals, from the perspective of the entire project lifecycle, its total cost of ownership (TCO) is lower:
Reducing labor costs: The biggest cost advantage is the saved installation time.
Reduce tool costs: No need to purchase and calibrate torque screwdrivers.
Reducing the cost of failure risk: Higher reliability reduces post maintenance, troubleshooting, and losses caused by downtime.
