Material Evaluation Of Push-type Terminal Connectors

The selection of materials for push connector block involves multiple factors such as conductivity, durability, and environmental adaptability, which not only affect the performance of push wire terminal block, but also influence production and maintenance strategies. Copper and copper alloys are mostly used as the base metal for conductive components because this material combination offers a good balance between electrical conductivity and mechanical strength, while meeting engineering requirements such as the number of insertion/removal cycles. Surface plating, such as nickel, tin, or even silver, is used to enhance surface properties and improve contact stability and oxidation resistance for specific applications.

The housing is typically made of thermoplastic or thermosetting plastics, whose electrical insulation and heat resistance must meet established safety standards. Different combinations of plastics can result in different performances of the push in terminal block wire connector device in terms of thermal deformation and mechanical stability.
