The Choice Of Material For Push-button Terminal Connectors Directly Affects The Durability Of The Equipment.

In electrical equipment design, the material composition of push wire terminal block directly affects the durability and stability of the overall device. Terminals are generally composed of conductive components, a spring structure, and an insulating shell. Copper or copper alloys (metal springs and contacts) are typically chosen as conductive metals to achieve good conductivity and mechanical strength. These materials are widely used in spring-type or push in terminal block wire connector internal components due to their low resistance and high conductivity.

The elastic element of the spring clamping structure is often made of stainless steel to ensure that the push in wire terminal block maintains a stable clamping force during insertion and removal. This continuous mechanical pressure ensures constant contact between the wire and the metal contacts, preventing loosening due to vibration, temperature changes, or other environmental factors.

The shell material is mostly thermoplastic engineering plastics, such as polyamide (PA66) or polycarbonate (PC), possessing good insulation, flame retardancy, and heat and shock resistance. This insulating shell protects the internal metal structure from external mechanical impacts, electrical short circuits, or environmental corrosion.
