Type-C-based USB Connector Capable of Transmitting Large Current

A Type-C-based USB connector capable of transmitting large current, comprising a housing, an upper insert member and a lower insert member, the upper insert member comprising an upper insulating body and an upper row of conductive terminal, the lower insert member comprising a lower insulating body and integrally formed metallic shielding layer and lower row of conductive terminal, wherein said upper row of conductive terminal comprises at least an upper ground terminal and an upper power signal terminal, and said lower row of conductive terminal comprises at least a lower ground terminal and a lower power signal terminal, characterized in that,

• each conductive terminal comprises a joint portion at a front end, a soldering portion at a rear end, and a main body provided within the insulating body and positioned between the joint portion and the soldering portion;
• the joint portion of the lower ground terminal comprises a ground base and a plate-shaped ground portion protruding downward from the ground base, the ground portion lies in a different plane from that of the ground base, the ground base is provided within the lower insulating body, and the ground portion emerges from the lower insulating body for contacting with the ground terminal of a joint connector;
• the joint portion of the lower power signal terminal comprises a power signal base and a plate-shaped signal power portion protruding downward from the power signal base, the power signal portion lies in a different plane from that of the power signal base, the power signal base is provided within the lower insulating body, and the power signal portion emerges from the lower insulating body for contacting with the power signal terminal of a joint connector;
• the ground base of the lower ground terminal, the power signal base of the lower power signal terminal, the main body of the lower ground terminal and the main body of the lower power signal terminal are all widened parts.
