Improve The Load Distribution Design Of Bimetallic Terminals To Prevent Single-terminal Overload.
The bi metal lugs connectors structural design allows for the connection of cable cores and leads to the connecting plate via a crimping sleeve. A well-designed bi metallic cable lugs main and auxiliary connecting plates distribute the load conductors across multiple connecting holes, reducing current and thermal stress in a single connecting hole. Generally, using a bimetal cable lug hole diameter that matches the wire diameter but lacks margin may lead to increased contact resistance in the crimping area due to poor contact or insufficient contact area, resulting in accelerated temperature rise during long-term operation.
When designing bimetal terminal lug, a hole diameter slightly larger than the actual wire diameter and a bimetallic lugs price cross-section are preferred, matching the cable capacity. This ensures sufficient contact area and good contact pressure after conductor insertion and crimping, reducing connection point resistance and distributing the thermal load caused by current. For multiple lead connections, separate clamping structures or multiple connecting holes should be used, rather than concentrating all current in a single hole.
