The invention discloses a connector for plugging of an electronic card. The connector comprises the components of a housing; an insulating body which is accommodated in the housing and is provided with an accommodating chamber for insertion of the electronic card; and a plurality of terminals which are kept in the insulating body, wherein each terminal is provided with an elastic cantilever and a gasket. The elastic cantilever is provided with a contact which electrically contacts with the plugged electronic card, and a free end which is placed on the gasket. The connector further comprises a plurality of blocking sheets. Each blocking sheet is arranged above the free end of a corresponding elastic cantilever and faces the gasket, thereby limiting the free end of the elastic cantilever between the blocking sheet and the gasket, effectively preventing overlarge upward warpage deformation of the free end of the elastic cantilever of the terminal, and prolonging service life of the terminal.
