Separate Leaf Spring type Tulip Contact
The tulip contact is consisted of moving contact-piece, leaf spring and contact-piece shelf. When a piece of leaf spring failed, the other contacts still work，which is more stable than the bundled type tulip contact. Due to R angle trunking is designed foreach contact-piece, the radiating performance of a whole contact is high.
It has been won the national utility models patent (patent number: ZL200920195577.7)
