Shuttered electrical connector

摘要

An electrical connector has a shutter arrangement which moves in the direction of plug insertion. The shutter has tabs which slide in grooves in the housing and grooves which pass over conductors in a plug receiving chamber. The shutter is moved to the back of the chamber when a plug is inserted and is biased by a spring to return to close the chamber when the plug is removed. The spring is formed of a pair of interconnected Z-shaped portion. On movement of the shutter in the direction of plug insertion, a free end of each portion moves in the shutter movement direction whereas an intermediate portion of each Z-shaped portion moves in a transverse direction.
