Assembly of electric connector

The connector has a printed circuit board in its interior to take place of known connection method of conductive wires, it can reduce the volume of connector effectively, the said connector has a first internal mould and a second internal mould, thus effectively improving the phenomena of plastic overflow in existing injection forming of internal mould and loose of the welding points, besides, it has a metal case, a part of the metal case extends outside the first internal mould to form an outer shield, thus it can effectively protect the electronic devices from electrostatic harm.
