Introduction
Terminal blocks are essential for secure and reliable electrical connections. Among the latest connection technologies, spring cage connection has gained popularity for its efficiency and performance. This blog explains how spring cage terminal blocks work, their benefits, and key applications in modern electrical systems.
1.How Spring Cage Connection Works
1-1 Definition and Mechanism
A spring cage connection is a type of terminal block connection that uses a spring mechanism to clamp wires securely. Instead of screws, the spring applies constant pressure on the conductor, maintaining stable electrical contact. This design compensates for vibration, thermal expansion, and conductor relaxation, ensuring long-term reliability.
