Therefore, the present application can achieve electrical connection between some of the conductive terminals on the electrical connector without the need for additional jumpers, allowing electronic devices equipped with the electrical connector of the present application to continue to develop in the direction of being thinner and smaller. In this embodiment, the lower row top conductive channel can, for example, provide for transmitting ground signals to meet the customization requirements of the electrical connector; the lower row top terminal welding structure 152 provides a welding circuit substrate.
