New description: [New technical field] This creation is about an electrical connector, especially an electrical connector that has both USB and eSATA interface connectors and can be combined into a multi-connector or individually used. [Prior Art] . The Universal Serial Interface Bus (hereafter referred to as USB) is currently the most common computer transmission interface, and in order to provide a faster transmission interface, many computers have begun to introduce SATA A eSATA, while in space With the full use of the f source, the USB and eSATA interfaces are integrated into one, which means that the same connector socket has both a USB & eSATA interface, and the same connector plug also has a matching USB and eSATA interface. The connector plug of the integrated interface is inserted into the connector socket with integrated interface, and the connection can be formed through the USB& eSATA interface at the same time. • Although the connector sockets and plugs that have both USB and eSATA interfaces are compatible with each other's, but they are all newly developed products, it is a natural trend to use connector plugs with integrated interfaces for new electronic devices. Although the connector plug has both USB and eSATA interfaces, it must be plugged into a compatible integrated interface connector socket in the integrated state, and the USB or eSATA interface can not be used independently, in other words, as a personal computer. Or a separate USB interface and eSATA interface on the notebook, new integrated electronic devices - the integrated interface connector plugs, the integrated interface connector plugs can not be selectively plugged into the 3 M366205 brain The USB or eSATA interface is detrimental to the application. It can be seen from the above that although the integration of various interfaces of the electrical connector plug is a general trend, the connector plug having the integrated interface cannot match the existing interface on the computer. The solution should be that the multiple interfaces of the integrated interface connector plugs can be used not only in the integrated state, but also in the individual interfaces as needed.

Contact, in this state, Two interfaces connected to the interface connector used for port corresponding to the agreement; if two rearwardly: a time shift 'the second connector retracted interface, the first interface connector =, and individually inserted into the interface port matching agreement. As can be seen from the above, this creation uses a special structural design to enable the first and fifth M366205 second interface joints to be used separately or in an integrated state, which not only meets the development trend of electrical connectors, but also satisfies existing computer resources.
