Why Are Copper Terminal Blocks Typically Equipped With A Base For Fixing And Mounting?

In industrial control cabinets, distribution boxes and other electrical devices, the copper terminal block is not used alone in the air; it is equipped with a bottom base for fixing and installation. This base is the mechanical foundation of the entire component structure, directly impacting the overall layout and subsequent maintenance.

Base designs accommodate different installation methods, commonly including rail mounting and panel mounting. Standard guide rails (such as DIN rails) provide a unified "mounting track" for electrical components, allowing multiple modules, including the copper distribution block, to be arranged sequentially on the control cabinet back panel, facilitating neat wiring and modular expansion. The base typically has a snap-fit ​​or slotted structure, enabling quick assembly and adjustment in conjunction with the rail.

Another installation method is to directly fix the copper terminal strip's base to the equipment panel or base plate with screws. This fixing method is more common in scenarios requiring more stable physical support, such as high-vibration machinery or heavy-duty cable connection environments.
