The utility model for the another kind of technical scheme that solves its technical problem and adopt is: a kind of electric connector, comprise insulating base, be coated on the outer metal shell of this insulating base and be assembled in plurality of terminals on this insulating base, this insulating base is extended with hyoplastron to accommodate described terminal, this metal shell comprises roof that is positioned at this hyoplastron top and the two side of being extended and being formed by roof, described metal shell also comprises by the two side diapire that inwardly turnover is extended in opposite directions again and riveted forms below described hyoplastron, described insulating base is provided with the support portion, and this diapire of holder is supported in this support portion.
Described support portion is provided with boss, and this boss is connected to the riveted place of described diapire.
Described roof, two side and diapire surround a coating portion jointly to accommodate described hyoplastron, and this coating portion and hyoplastron constitute interface jointly.
Described interface is high-definition media interface (HDMI).
The beneficial effects of the utility model are: electric connector of the present utility model, the coating portion of its metal shell is by roof, two side and the diapire that is formed by the inside turnover in bottom, two side surround, the bottom of insulating base is provided with a support portion, the diapire of the coating portion of the described metal shell of holder is supported in the upper end of described support portion, the lower end of described support portion compresses wiring board, because the setting of this support portion, make metal shell and insulating base more firm between the two, also make the electric connector monnolithic case more complete, more can strengthen the positioning and fixing between electric connector and circuit board, the useful life that helps improving electric connector.
