Stamped Copper Terminal: Classification And Manufacturing Process Analysis

In power systems, wiring components are core parts ensuring stable circuit connections. Stamped Copper Terminals, with their excellent conductivity and reliable connection characteristics, have become the mainstream choice for wire interconnection scenarios. These components are suitable for large-scale line interconnection needs and are widely used in terminal blocks, junction boxes, and other equipment. They cover various specifications, including single-layer, double-layer, current-specific, voltage-specific, general-purpose, and disconnectable types. Sufficient crimping area ensures stable contact and meets the requirements of high current flow.

Material is key to component performance. Copper Stamped Electrical Contacts primarily use copper and phosphor bronze as core materials, formed through machining processes. Their appearance is often shaped like a spatula head, with a fixed threaded edge on one side and a side suitable for connecting the copper core of stripped cables. Structurally, they are mainly divided into plug-type and crimp-type. The oil-sealed structure offers better sealing, effectively isolating air and slowing down the oxidation process. To further enhance protective capabilities, the component surface undergoes plating treatment. Common processes include aluminum plating, nickel plating, copper plating, and copper alloy plating, fundamentally preventing surface oxidation and blackening issues and extending service life.

The forming process directly affects component precision and production efficiency. Copper Sheet Metal Parts primarily uses copper as its raw material. This material has low yield strength, excellent plasticity, and the component's axisymmetric structure makes it naturally suited for cold extrusion forming. Tube cold extrusion mainly falls into two modes: with a mandrel and without a mandrel. The mandrel-based process can precisely define the forming inner diameter, but the die structure is complex, and it is mostly used for high-precision workpieces with constant or thin walls. The mandrel-less process involves axial elongation and wall thickness increase during forming, suitable for products with less stringent requirements on inner diameter and wall thickness. The die structure is simple, easy to manufacture, and highly efficient to operate. A large cross-sectional reduction can be achieved in a single extrusion, reducing deformation processes and meeting the production needs of this type of component.

Standardized processes ensure mass production quality. Copper Pressed Parts' cold extrusion dies adopt a modular structure, resulting in a clear and standardized production process. During operation, the upper die is first raised, and the blank is vertically placed into the lower die for positioning. Then, the upper die presses down to complete the stamping process. After stamping, the upper die quickly resets, and a specialized device ejects the formed workpiece from the lower die, yielding the finished product. This entire process is repeated cyclically, achieving efficient and continuous production. Strict process control ensures that each product maintains dimensional stability and consistent performance, meeting the high reliability requirements of the power industry for connecting components.
