Electrical socket outlet and plug system for charging station of electric car, has rack gear and teeth converting rotating movement of rotary ring into movement of diaphragms between closure and opening positions

摘要

#CMT# #/CMT# The system has a socket (1) and a plug that are joined with each other in plug direction (X). A closure element (100) is arranged in front of the socket. The closure element comprises a rotary ring (120) with a through-hole (126), where the plug is engaged with the through-hole in a torque-proof manner. Diaphragms (130, 130') are movable between a closure position and an opening position. A rack gear (131') and teeth (121) of the rotary ring convert rotating movement of the ring into movement of the diaphragms between the closure and opening positions. #CMT# : #/CMT# Independent claims are also included for the following: (1) a method for controlling access of a plug to a socket (2) a closure element for controlling access of a plug to a socket. #CMT#USE : #/CMT# Electrical socket outlet and plug system for a charging station of an electric car. #CMT#ADVANTAGE : #/CMT# The system enables realizing secure and robust control of authorized access of the plug to the socket. The system can be installed in a narrow installation space. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an exploded perspective view of a closure element with a socket.
