Electrical connector having dust-proof device with self-driven arrangement

An electrical connector comprising:

• an insulative housing;
• a plurality of contacts retained in the housing;
• a shell enclosing the housing and defining a mating cavity having a mating opening at a front end thereof;
• and
• a dust-proof device movably attached to the mating opening and defining a dust-proof member movable between a closed position and an open position, a resilient connecting member attached to the dust-proof member, and a pivoting portion connecting the dust-proof member with the shell by a shaft formed on the resilient connecting member running through the pivoting portion, the shaft rotating along the pivoting portion between a first position in which the dust-proof member stays at the closed position and a second position in which the dust-proof member stays at the open position;
• wherein a peak point is provided on the pivoting portion and disposed between the first position and the second position, and the dust-proof member will automatically return to the closed position when the shaft rotates between the first position and the peak point and automatically reach to the open position when the shaft rotates between the peak point and the second position.
