Description

Technical Field

HDMI can be used in set-top boxes, DVD players, personal computers, video game consoles, integrated amplifiers, digital audio and televisions. HDMI can transmit audio and video signals at the same time.

[0003] The existing HDMI connector often generates signal interference when in use, making its signal unstable. To solve the above problem, the Chinese utility model patent with the announcement number CN202308603U discloses a socket structure of an HDMI connector with a shielding function, including an insulating body, the insulating body extends forward with a terminal body, the terminal body is formed with an upper terminal piece slot and a lower terminal piece slot, and the terminal piece is embedded in the upper terminal piece slot and the lower terminal piece slot; and an outer shell that clamps the insulating body and the terminal body, the outer shell is formed with two symmetrical outer shell springs; and a plurality of pins embedded in the rear end of the insulating body and electrically connected to the terminal piece; the outer shell of the socket structure of the electronic connector adopts a metal shell with a shielding function. It adopts a metal shell with a shielding electromagnetic interference function, and the shell can be connected with the grounding circuit of the main device to eliminate the electromagnetic waves of the insulating body of the connector. When transmitting high-frequency electronic information, the signal is stable, which can ensure high-fidelity information transmission.
