2. Description of Prior Art
Due to the development of the electronics industry, many types of electronic devices are now popular and surronding people's life. In order to transmit control commmands, multimedia data and power, most electronic devices are arranged with at least one electrical connector.
The most popular electrical connector in the market is universal serial bus (USB) connector. General speaking, the most popular USB connector is USB Type-A connector. Besides, USB Micro-B connector is another USB interface which is smaller than USB Type-A connector, and is mostly adopted in portable devices such as smart phones, tablets, etc. Furthermore, USB Implementers Forum announced USB Type-C interface, which is made for slighter, thinner devices.
In order to save the arranging space of the mainboard, most computers (such as laptops or PCs) are arranged with one or more composite electronic connectors. In particular, the most popular composite electronic connector is the connector that combined by two USB 3.0 Type-A connectors or one USB 3.0 Type-A connector and one USB 2.0 Type-A connector.

As a result, if a current composite electronic connector needs to be update to combine a USB Type-C connector with a USB 3.0 Type-A connector, or to combine a USB Type-C connector with a USB 2.0 Type-A connector, the pin difinition of a mainboard of a computer needs to be changed following USB 3.1 Type-C standard (for example, traditional pin difinition, such as nine pins plus nine pins or nine pins plus four pins, needs to be changed into, for example, nine pins plus twenty-four pins or four pins plus twenty-four pins). Besides, the circuit design of the mainboard also needs to be extremely adjusted. Therefore, the cost of development and manufacture of the mainboard will be increased.
The present invention is to provide a composite electronic connector, which may connect with a mainboard through inserting holes adopted with USB Type-A standard and make the mainboard to use a USB Type-C connector of the composite electronic connector.
In one of the exemplary embodiments, the composite electronic connector comprises an insulating housing, a USB Type-C connector and a USB Type-A connector which are arranged in the insulating housing. The USB Type-C connector comprises a circuit board, a connecting line and a plurality of transferring terminals. One side of the circuit board is arranged with twenty-four golden fingers, other side of the circuit board is connected with the plurality of transferring terminals. The connecting line is used to integrate signal transmitted through the twenty-four golden fingers of the USB Type-C connector into USB Type-A standard adopted outputting signal, and outputs the outputting signal through the plurality of transferring terminals.
In comparison with prior art, the composite electronic connector of the present invention may connect with an external mainboard through USB Type-A adopted inserting holes, so as to connect with the mainboard and make the mainboard to use the USB Type-C connector on the composite electronic connector without changing the circuit arrangement of the mainboard, which is very convenient.
