Connecting holes and corresponding online transmission of various portable electronic devices such as mobile communication devices and digital cameras.

As the main trend of electronic devices is still light, thin and small, relatively, the electrical connectors on the electronic devices must also reduce the volume occupied, especially the need to install multiple electrical connectors that meet different electronic signal transmission specifications. For plugging in different plug connectors, since the installation of each electrical connector requires a certain volume, and the space between the electrical connectors is required, the space between the electrical connectors becomes a waste of space; An all-in-one electrical connector that integrates different electronic signal transmission specifications.

However, since the all-in-one electrical connector is provided with multiple sets of connecting terminals, how to electrically connect the pins of the multiple sets of connecting terminals with the preset circuit substrate becomes a problem to be solved. For example, if the pins of multiple sets of connecting terminals are electrically connected to the preset circuit substrate by through-hole welding, the position of the through-hole on the circuit substrate cannot be provided with multi-layer circuits, resulting in a waste of limited circuit design space. Also, for example: if the pins of multiple sets of connection terminals are electrically connected to the preset circuit substrate by surface welding, the pins at the bottom of the electrical connector will be shielded by the electrical connector, causing surface soldering problems. The difficulty is relatively increased.
