The design of the modern electronic device, except for must has multiple functions, but it also trend to achieve slightness, thinness, shortness and smallness in outer appearance. In order to seek such a trend, the components disposed in the electronic device must be reduced in volume correspondingly, and the connectors used therein also must be reduced in volume without exception. For example, the USB connector has developed a mini USB connector, and the digital video signal transmission interface evolves from a digital video interface to a high definition multi-media interface having a smaller volume and a faster transmission speed.

现代电子产品的设计除了要功能多样外，在外观上的趋势是追求轻、薄、短、小，为了追求这样的趋势，电子产品内的各个零件也必须跟着将体积缩小，其所使用的电连接器当然也不例外，如通用串行连接埠推出迷你版的通用串行连接端口，而数字影音讯号的传输接口也由数字视觉接口推演到体积较小，传输速度更快的高速高解析多媒体接口。
