An electronic connector is a motor system that provides a separable interface to connect two sub-electronic systems. Simply put, the components used to complete the electrical connection between circuits or electronic machines are called connectors, which are the bridges between the two. DP connectors are one type of electronic connectors.

[0003] DP connector is the abbreviation of DisplayPort connector. DisplayPort, also known as high-definition digital display interface, is a digital video interface standard promoted by the Video Electronics Standards Association. It is mainly used to connect video sources to devices such as monitors, connect computers and screens, or computers and home theater systems. It also supports carrying audio, USB and other forms of data.
