Press-type Terminal Connectors Require High Abrasion Resistance.

push connector block typically employs a combination of a metal conductor with spring-loaded clips and an insulating shell. After the wire is inserted, the spring applies a continuous clamping force, thus forming a stable electrical connection. During repeated insertion and removal operations, the metal contact surfaces between the spring, the wire, and the internal terminals are prone to minor wear. If wear-resistant metals or fatigue-resistant clips are not selected, long-term use may lead to a decrease in clamping force or oxidation of the contact surfaces.

During the design and material selection phase of push wire terminal block, it is crucial to pay attention to the elasticity retention and wear resistance of the metal clips. Use appropriate high-hardness or surface-treated metal materials to avoid excessive connection cycles of push in terminal block wire connector, which could lead to a decline in its performance. The shell material must also balance mechanical strength and insulation performance to withstand the friction and impact from frequent insertion and removal.
