AI Technical Summary
Existing connectors are prone to electric field concentration between pins in high-voltage, high-humidity, or pollutant environments, leading to frequent creepage phenomena and affecting the safety and reliability of equipment operation.
A plug structure was designed, including a base, first and second terminals, signal pins, and a crown spring. By arranging the insertion platforms at intervals and setting the crown spring, the contact area is increased, the creepage distance and insulation strength are improved, and the insertion and removal smoothness is enhanced.
It improves the safety and reliability of connectors, reduces the occurrence of creepage failures, enhances the durability and stability of plugs, and is suitable for high current transmission.
