Why Are Copper Terminal Blocks Not Usually Designed As Pluggable Structures?

The basic definition of copper terminal block is that it is a fixed conductive connector used to carry and distribute current, and to stably fix the wires by means of screws or crimping.

The structure of copper distribution block typically emphasizes the reliable clamping of the connection surface and the continuity of the conductor. The contact points formed by metallic materials (such as copper and copper alloys) and fasteners bear a constant current carrying requirement during long-term operation, and are not designed for repeated plugging and unplugging cycles like plugs/sockets. The pluggable connection structure must be designed with high elasticity and positioning accuracy between the mating surface and the elastic contact element, which will significantly affect the overall dimensional tolerances and contact pressure distribution of copper terminal strip, and may also lead to wear, loosening, and even degradation of the conductivity of the contact point surface.
