ABSTRACT:
Disclosed is an improved jack structure, includes a main body, a cover, two protective covers, a lock piece and a conductive piece. When an object is inserted into a single one of insertion holes each corresponding to one of the protective covers on the main body, a corresponding one of the protective covers is pushed to move. A protrusion of the pushed protective cover then pushes an urging portion of the lock piece and the urging portion is stopped by the other one of the protective covers. Therefore, the improved jack structure can be prevented from being inserted with an acute object and thus from occurrence of electric shock.
