Embodiment 1

[0016] Such as figure 1 The shown HDMI audio-video switcher includes a casing, a male connector 1 and a female connector both arranged on the casing, there are multiple female connectors, and the casing includes a first A housing part 2 and a second housing part 3 for covering the female joint, the first housing part 2 is provided with a first connecting part 21, and the second housing part 3 is provided with a second The connection part 31, the first connection part 21 and the second connection part 31 are connected by a conductive metal shaft, and the first connection part 21 and the second connection part 31 are provided with wires connected to the metal shaft. The interface control module and indicating module of the HDMI audio-video switcher can be arranged in the first casing part or the second casing part or in the first casing part and the second casing part respectively according to specific conditions. The wires are respectively introduced into the internal installa...

Embodiment 2

[0018] Such as figure 1 The HDMI audio-video switch shown in this embodiment is optimized on the basis of the above-mentioned embodiments, that is, there are two second connecting parts 31 located on both sides of the first connecting part 21 respectively. With this structure, compared with the structure in which only one first connecting portion 21 and one second connecting portion 31 are provided, the structure is more stable, and the structural requirements for the metal shaft are lower.

[0019] The first connecting portion 21 and the second connecting portion 31 are in a cylindrical structure with a cut surface. With the first connection part 21 and the second connection part 31 of this structure, the rotation operation of the second case part 3 relative to the first connection part 21 is facilitated.

[0020] The metal shaft is arranged on the centers of the first connecting portion 21 and the second connecting portion 31 .

Description

technical field [0001] The present invention relates to the field of audio and video switching devices, in particular to an HDMI audio and video switcher. Background technique [0002] High-definition multimedia interface, or HDMI switcher, is a fully digital image and sound transmission interface standard that can transmit uncompressed audio signals and video signals. Because the same cable is used for audio signal and video signal, the installation and connection of the system are greatly simplified. HDMI can be used in common media devices such as DVD players, set-top boxes, high-definition TV boxes, game consoles, and televisions, and has now become an essential interface for media devices. [0003] The HDMI audio and video switcher is used for signal transmission between the signal of the signal source device and the display device. The existing HDMI audio-video switcher includes a casing, and a male connector and a female connector are arranged around the casing, whi...
