The Housing Of The Copper Terminal Block Must Meet The Standard Requirements.

For copper terminal block applications, the design of the enclosure is not arbitrary but strictly constrained by standards and specifications. According to current standards, such as GB/T 14048.7 for copper distribution block, its mechanical structure, electrical insulation, resistance to damp heat, and environmental adaptability all depend on the quality and construction of the enclosure.

For copper terminal strip applications, the enclosure must ensure stable positioning of the wires and metal contacts during screw clamping or insertion/removal, and must not cause poor contact or detachment due to vibration or temperature changes. Relevant standard clauses require the clamping device to complete pull-out tests and dielectric tests, and pass damp heat environment tests.

Plastic or metal enclosures must also possess sufficient insulation performance and protection rating to prevent the risk of electric shock from exposed metal parts of the terminals. For certain high-safety applications, the enclosure design must meet the specifications regarding insulation distances and clearances.
