Electrical connector assembly

The present invention relates to an electrical connector assembly, and more particularly to an electrical connector assembly having two different interface specifications and suitable for use in a USB interface of a car audio control panel.

According to the audio-visual system on the car, it has evolved from the early radio and cassette to the current CD (Compact Disc) and MD (Mini Disc). With the advent and development of digital audio and video, people hope to use MP3 (Moving Picture Experts Group Audio Layer III) video player, portable device and other mobile devices to listen to music. Since the data in the car needs to be transmitted to the USB (Universal Serial Bus) connector through the adapter through the corresponding connector, the conventional adapter uses the connector to pass the PCB (Printed Circuit Board). Printed circuit boards are connected together to achieve data transfer.

However, the above-mentioned electrical connector combination requires two PCBs to be connected together, and the manufacturing cost is greatly improved. At the same time, the PCB and the two connectors need to be soldered by SMT (Surface Mounted Technology), which not only increases soldering and testing.
