DETAILED DESCRIPTION

[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments. Example 1

[0023] Ordinary audio interfaces are easy to loosen. In order to improve the connection stability of the audio interface, an audio interface for audio data transmission is designed. The specific solution is as follows:

[0024] like Figure 1-3 As shown, an audio interface for audio data transmission includes a plug-in base 1 and a rubber sleeve 2. A sinking groove is provided at the front end of the plug-in base 1, and the rubber sleeve 2 is installed in the sinking groove. A slot 101 is also provided at the rear of the plug-in base 1. The slot 101 is coaxial with the sinking groove. At least one fixed structure 4 extending forward is provided on the periphery of the plug-in base 1. The fixed structure 4 is a movable part 403. A buckling part 402 is provided at the front end of the fixed structure 4, and a movable part 403 is provided at the rear of the fixed structure 4.

[0025] The fixing structure 4 is in a J-shaped structure, and a rotating shaft 401 is provided at the corner of the J-shaped structure. The fixing structure 4 is screwed to the plug base 1. The front end of the hook-shaped part of the J-shaped structure exceeds the front end of the interface in the initial state, so that when the plug 5 is inserted, it is first released to the front end of the hook-shaped part, so that the fixing structure 4 is actuated to buckle and fix the plug 5.

[0026] A pair of relatively arranged fixing structures 4 are provided on the plug-in base 1 for easy operation. In the present embodiment, the fixing structures 4 are provided on the upper and lower sides of the plug-in base 1. In other schemes, the fixing structures 4 are provided on the left and right sides of the plug-in base 1. When in use, the fixing structures 4 on the upper and lower sides can play a clamping role to clamp the outer wall of the plug 5. The front end of the fixing structure 4 remains dropped when the plug 5 is not plugged in. During the insertion of the plug 5, the front end of the fixing structure 4 will be lifted up and moved along the outer wall of the plug 5 toward the card slot 501 until it is inserted into the card slot 501.

[0027] An installation groove 301 for installing the fixed structure 4 is opened on the plug-in base 1, and the fixed structure 4 can move within the range of the installation groove 301. Similarly, the installation groove 301 is opened on the upper and lower sides of the plug-in base 1, and an integrated installation part 3 is provided on the plug-in base 1. The installation part 3 protrudes from the plug-in base 1, and the installation groove 301 is opened in the installation part 3, and the front side of the installation groove 301 is an opening.

[0028] A contact portion 404 extending forward is provided at the front end of the snap-fit ​​portion 402 for releasing the snap-fit ​​portion 402 from snapping. When in use, the contact portion 404 contacts the front of the pressing plate 503, and the contact portion 404 is lifted up by the action of the pressing plate 503, thereby disengaging the snap-fit ​​portion 402 from the card slot 501, making it easier to pull the plug 5 out.

[0029] It also includes a plug 5 that matches the audio interface, and an outer wall of the plug 5 is provided with a slot 501 that matches the buckle portion 402 .

[0030] A limiting portion 502 protruding outward is provided on the outer wall of the plug 5, and a channel is formed between the limiting portions 502. The channel is in the same straight line as the fixed structure 4 to limit the fixed structure 4. A limiting portion 502 is provided on the left and right sides of each fixed structure 4. When the plug 5 rotates, the limiting portion 502 cooperates with the fixed structure 4 to prevent the plug 5 from rotating forward or reversely, thereby preventing the plug 5 from rotating loose.

[0031] A pressing structure is provided at the rear of the plug 5 for releasing the fastening structure 4 .

[0032] The pressing structure includes a pressing plate 503 and a torsion spring 504. The pressing plate 503 is screwed and installed on the outer surface of the plug 5. The torsion spring 504 is installed at the screwed connection between the mounting plate and the plug 5. The two ends of the torsion spring 504 respectively abut against the pressing plate 503 and the plug 5. When the plug 5 is inserted, there is no need to use a pressing structure. The ordinary plug 5 can be inserted to achieve fixed insertion. When the plug 5 is pulled out, pinching the rear part of the pressing plate 503 on the upper and lower sides can make the front end of the pressing plate 503 tilt up, so that the plug 5 is out of the snap-fit ​​state, and then the plug 5 can be pulled out.

[0033] Working principle:

[0034] When the plug 5 is inserted, the user can pinch the left and right sides of the plug 5 with the thumb and index finger and insert it normally as an ordinary plug 5. When the plug 5 is inserted, the outer wall of the plug 5 will push the fixed structure 4 upward, and the front end of the fixed structure 4 will be close to the outer wall of the plug 5. When the plug 5 is inserted to the bottom, the buckling part 402 at the front end of the fixed structure 4 will fall into the card groove 501 on the outer wall of the plug 5, completing the plug-in fixation, which is convenient and quick. When the plug 5 is pulled out, the user can also pinch the rear part of the pressing plates 503 on the upper and lower sides with the thumb and index finger to make the fixed structure 4 stick to the outer wall of the plug 5. At the same time, the movable part 403 at the rear of the fixed structure 4 will protrude forward, causing the plug 5 to be pushed outward, so that the user can pull out the plug 5 more easily.

[0035] The audio interface of the present invention is based on the RCA connector, which is suitable for music enthusiasts. On the basis of the RCA connector, there is no need to modify the structure used for audio transmission. The interface or plug 5 of the present invention is suitable for ordinary plugs 5 or interfaces and has wide applicability. Considering the improvement of the connection stability of the audio interface, a fixing structure 4 and a pressing structure for improving the connection stability are provided on the audio interface and the plug 5, so that the audio interface will not be easily loosened. When the audio interface is plugged in or unplugged, the user can complete the plugging and unplugging action with one hand, without the need for both hands or additional tools, and the operation is more convenient. Example 2

[0036] In this embodiment, the structure of the audio interface and the plug 5 is basically the same as that in Embodiment 1, except that a pressing portion is provided on the front of the pressing plate 503, so that the front plate of the pressing plate 503 is a V-shaped structure. After the plug 5 is plugged in, the pressing portion fits against the top of the contact portion 404, and even if it receives a certain external force, the fixing structure 4 will not easily detach from the slot 501.

[0037] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
