Proper Insertion Force And Precise Matching Are Crucial For Bimetallic Terminals.
The contact portion between bimetallic lugs and the wire must match the design dimensions. Any misfit may result in a "loose insertion" at the connection point. The connection components need to withstand electrical, thermal, and mechanical loads; therefore, installation accuracy is a fundamental requirement.
For the bi metal cable lug connector, the wire insertion force needs to reach the designed position inside the connection hole to ensure sufficient contact area between the metal parts. Insufficient insertion depth will create gaps at the contact interface, making the contact point prone to displacement during vibration or thermal expansion and contraction cycles. This not only hinders stable conduction but may also develop into a loose contact over time. During insertion, it is necessary to check whether the metal and bi metal lugs connectors are firmly attached by gently pulling or other means to prevent unstable contact caused by temperature changes.
