[0002] HDMI is the abbreviation of High-Definition Multimedia Interface. It is a fully digital video and sound transmission interface that can send uncompressed audio and video signals. HDMI can be used in set-top boxes, DVD players, computers, televisions, game consoles, integrated amplifiers, digital audio and televisions and other devices.

[0003] In the prior art, an HDMI connector includes an upper terminal group and a lower terminal group. A plurality of first welding pins of the upper terminal group are arranged side by side, and a plurality of second welding pins of the lower terminal group are arranged side by side, so that an installation space for inserting a PCB board is formed between the first welding pins and the second welding pins. The first welding pins and the second welding pins are respectively welded to the upper end face and the lower end face of the PCB board. With this structure, when the PCB board is inserted into the installation space, the welding pins are easily contacted, which may cause the welding pins to deform and break, thereby causing the entire HDMI connector to be scrapped, which is not conducive to automated assembly. Moreover, the size of the installation space is fixed, but the thickness of the PCB board is different, so that this HDMI connector cannot adapt to PCB boards of different thicknesses and sizes, and has poor flexibility in use.
