[0003] To this end, waterproof vertical Type-C connectors are currently available on the market. These waterproof vertical Type-C connectors primarily consist of an insulating body, multiple conductive terminals, and a shielding shell. The insulating body includes a base, a pedestal extending upward from the base, and a tongue extending upward from the base. The multiple conductive terminals are secured within the insulating body, each having a contact portion and a soldering portion. The contact portion is exposed on the side of the tongue, while the soldering portion extends beyond the base. The shielding shell covers the insulating body.
