  • Patent number: 7416442
    Abstract: A connector has a combination of a terminal set and a back cover together disposed inside a shell, where the shell and the back cover are further covered by a metal mask. The terminal set consists of at least one connecting port. The connecting port includes a circuit board and a hollow pin base disposed on the circuit board. The front side wall of the pin base is formed with a grating part so that the hollow part of the pin base has a larger space to accommodate electronic devices. A ground window is formed on the back cover so that the ground node of the circuit board is directly exposed. The metal mask is thus directly in touch with the ground node to simply the assembly process of the connector.
