Abstract: An electrical connector including a jack and a plug is disclosed. The plug includes a spring biased push button slidably anchored in an opening on a top shell and including an indentation at either side, and a front trigger adjacent the indentation; two U-shaped positioning devices each comprising a front first protrusion at one end and an intermediate second protrusion; and a shield case comprising a grounding plate. The push button is pushed forward to engage with a front end of the opening in an inoperative state. The push button is adapted to push rearward to cause the trigger to push and press down the second protrusions until the first protrusions clear internal openings of the jack such that a subsequent pulling will disengage the plug with the jack.
