[0002] In addition to conventional VGA, USB and other interfaces, the car's central control host is usually also equipped with an HDMI interface, which enables lossless transmission of audio and video data between the terminal device and the car's central control host through an HDMI cable.

[0003] Upon investigation, the disclosure (announcement) number: CN205248538U discloses an HDMI cable plug-in fixing structure for an in-vehicle navigation multimedia system, which discloses a plug connected to an HDMI cable and a socket provided on an in-vehicle central control host. The plug includes a plug body, an HDMI male head connected to the front end of the plug body, and a fixing seat provided on the plug body. A fastening screw is threadedly connected to the fixing seat. The socket includes a guide groove for accommodating the plug body, an HDMI female seat for plugging with the HDMI male head, the HDMI female seat is provided at the bottom of the guide groove, and a threaded hole is further provided on one side of the guide groove to cooperate with the fastening screw. The utility model of the HDMI cable plug-in fixing structure for an in-vehicle navigation multimedia system can not only effectively reduce the shaking of the plug and socket, ensure the stability and reliability of the fixation of the HDMI connection socket, and extend the service life of the plug and socket, but also has a simple structure and is easy to assemble, thereby improving assembly efficiency and vehicle compatibility, and facilitating user assembly and use.

The upper and lower sides of the HDMI connector 7 are provided with connecting splints 58 that cooperate with the locking splints 54, and the ends of the connecting splints 58 are provided with connecting claws 59. Mutually cooperating inclined surfaces are provided on the locking claws 55 and the connecting claws 59, and the initial position of the locking splint 54 is limited by the positioning seat 57, so that there is a certain gap between the locking splint 54 and the rectangular positioning tube 52, which is convenient for the installation of the HDMI connector 7 to directly plug the connecting splint 58 into the interior of the locking splint 54.

[0026] As a further implementation plan of the above technical solution: screws are provided at the four corners of the mounting backplate 51, and the mounting backplate 51 is fixedly mounted on the mounting backplate 4 by screws. The mounting backplate 51 is mounted on the mounting backplate 4 by screws, and the rectangular positioning tube 52 is installed simultaneously to realize the positioning of the rectangular positioning tube 52 and the plug interface 6.

[0027] As a further implementation plan of the above technical solution: the rectangular positioning tube 52 is made of acrylic material, which is convenient for observing the insertion of the HDMI plug connector 7 inside the rectangular positioning tube 52. The internal size of the rectangular positioning tube 52 is compatible with the HDMI plug connector 7, ensuring the stability of the HDMI plug connector 7 after being plugged into the rectangular positioning tube 52, and ensuring that the HDMI plug connector 7 can be accurately positioned with the plug interface 6.

[0028] As a further implementation plan of the above technical solution: the upper and lower sides of the rectangular positioning tube 52 are fixedly connected with a hinge seat 53 that cooperates with the locking clamp 54. The position of the locking clamp 54 is restricted by the hinge seat 53 to ensure that the locking clamp 54 is firmly installed on the rectangular positioning tube 52 and can rotate stably. The locking clamp 54 is hinged in the hinge seat 53, and an adjustment arc plate 56 is provided at one end of the locking clamp 54 away from the locking claw 55, which is convenient for pushing the locking clamp 54 outward by adjusting the arc plate 56, so as to release the lock of the locking clamp 54 on the HDMI connector 7.
