Stacked electrical connector

This creation relates to a stacked electrical connector, and more particularly to a stacked electrical connector that can be used to plug two connectors that conform to the USB 3.0 transport protocol.

Today's electronic technology is developing rapidly, and the type of computer has evolved from a desktop computer to a small and easy-to-carry notebook computer. It is common in all corners of the society, when users want to transmit data, transmit signals, or When connecting with other peripheral devices, a so-called peripheral device interface is required. Currently, a USB (Universal Serial Bus) interface is generally used as a mainstream, and a conventional connector has an insulating body, and the terminal body is provided with a terminal group on the insulating body. In order to expose the plurality of contact ends of the bottom of the insulating base, the other side is a plurality of welded ends bent to extend outside the insulating seat, and the outer cover of the insulating cover is covered with a shielding shell, and the connector of the USB2.0 transmission protocol is formed through the above structure.
