Reliability And Rust Prevention Optimization Analysis Of Push-in Terminal Blocks Under High Load Conditions

Although push in wire terminal block can be quickly pushed in without tools, saving wiring time and having an advantage in installation efficiency, it is prone to poor contact and abnormal temperature rise under long-term vibration, high temperature or alternating high current conditions. In addition, if the crimping sleeve is not used according to the specifications or the material is improperly selected during construction, it may also cause the contact points of push wire terminal block to loosen, corrode or even rust the screws. Therefore, when selecting, installing and accepting the product, you should give priority to referring to the manufacturer's information, operate according to the rated wire and connection method, and perform post-tests such as thermal imaging or tension to ensure long-term reliability.
