Patent ID: 7163412

Claim:
An electrical connector comprising: an insulative housing; a plurality of terminals retained in the housing and comprising, a controlling signal terminal for transmitting locking/unlocking signals and power terminal for supplying power; a moveable locking device for locking with a complementary connector; an electromagnetic anti-disengagement device comprising a holding component defining a holding position and a releasing position and actuated by the power provided by the power terminal to be reversible between the two positions; wherein when the power is provided on the electromagnetic anti-disengagement device, the holding component is pushed into the holding position so as to prevent the locking device moving to lock or unlock the complementary connector; when the power turns off, the holding component automatically returns back into the releasing position, the locking device can be moved to lock or unlock the complementary connector; further comprising a printed circuit board having a controlling element for electrically connecting the terminals with the electromagnetic device; wherein the controlling signal controls the power of the power terminal turning on or off by transmitting locking/unlocking signals into the controlling element; wherein said anti-disengagement device includes an electromagnetic component used for controlling the holding component moveable nearby the locking device to block/unblock movement of the said locking device; wherein the electromagnetic component has a main body being immobile relative to the housing and a moveable portion having a distal end retained in the holding component.
