Material Selection And Performance Analysis Of Press-type Terminal Connectors

The surface treatment and substrate type of electrical connectors directly affect the chemical stability of the metal contact surface of push wire terminal block, which in turn affects its contact resistance, oxide layer accumulation, and other phenomena.

For push in terminal block wire connector, its construction is inseparable from the mechanical cooperation between the metal conductor and the contact component. Conductors typically use copper or copper alloy substrates with plating to enhance the oxidation resistance of push in wire terminal block. Common surface coatings include tin and nickel, which can slow down the oxidation process of push fit terminal block connector to some extent and improve the contact stability with cables.

The contact surface condition, substrate selection, and surface treatment of push connector block comprehensively determine the long-term stability of electrical connections, and the material combination corresponding to different application scenarios becomes an important part of the technology evaluation.
