ELECTRICAL PLUG CONNECTOR

摘要

The invention relates to an electrical plug connector including a plug and a coupling in which radially spring elastic annular contact lamellas are arranged. In order to prevent corrosion when the plug and the coupling are made from different materials the invention proposes a tin plated bushing in the coupling in which bushing the contact lamellas are arranged.
