The tension spring type

The tension spring design allows the user to connect and disconnect wires by opening the spring with a screwdriver or operating lever – there is no time-consuming rotation of a screw or need for a special tool. The tension spring type is very useful in difficult operating conditions, for example where there is a risk of vibration, impact, shock or extreme temperature fluctuations. The spring compensates for the stress-dependent and thermal compression/flow performance of the wires, and this ensures a gas-tight and maintenance-free electrical connection. This dynamic clamp connection system creates a reliable contact, protects the connection against vibration, and is becoming more and more popular in industrial and traffic technology applications.
