Embodiment:

Below be merely preferred embodiment of the present invention, do not limit protection scope of the present invention with this.

See shown in Fig. 1-6, the electric connector of electronic communication product provided by the present invention, it comprises an insulator 1 and metal shell 2, terminal 3.Described metal shell 2 front end upper surfaces are provided with the metal buckle 21 that raises up of integrated molding, and described metal buckle 22 has two.When electric connector was pegged graft, metal buckle 21 can be buckled on the grafting thing, makes it difficult drop-off.

The upper and lower layer in described metal shell 2 rear ends is provided with the clamping sheet 23 to outer lug, and clamping sheet 23 is provided with hole clipping 24, and metal shell 2 rear end left and right sides are provided with edge 22.The card that insulator 1 is provided with is established the limit groove of edge 22.
