Description

Technical Field

[0001] This utility model belongs to the technical field of audio cables, and in particular relates to an audio cable that prevents loosening. Background Technology

[0002] The existing Chinese patent database discloses a patent entitled "An Audio Acquisition Cable," application number CN202322758653.3, application date 2023-10-16. This patent relates to the field of audio acquisition cable technology, and includes a USB connector. Multiple audio cables are evenly arranged on one end of the USB connector. Each audio cable has an audio connector at one end. A protective cover is fitted onto the outer wall of the audio cable. An annular groove is formed on the inner wall of the protective cover, and a marking card is placed within the groove. An annular block is located at one end of the groove. This invention, through the use of the protective cover, facilitates the fixing of the audio cables and audio connectors, preventing breakage at the connection point and ensuring the normal operation of the audio acquisition cable, thus extending its service life. Simultaneously, the combined use of the annular groove and marking card facilitates marking of the audio acquisition cables, preventing excessive audio cables from becoming tangled and hindering accurate connection, further facilitating connection and improving the working efficiency of the audio acquisition cable.

[0003] Existing audio cable connections are prone to fatigue at the connectors after prolonged use, which can cause the connectors to detach and pose a hazard. Therefore, this solution aims to propose an anti-loosening audio cable that uses a limiting component at the connector to prevent the fiber optic cable connector from detaching, thus ensuring safety during long-term use. Utility Model Content

[0004] The technical problem this invention aims to solve is how to reduce the risk of audio cables coming loose during use. To address these shortcomings, this invention provides an audio cable designed to prevent loosening.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] An anti-loosening audio cable includes a cable body, one end of which is provided with a male connector and the other end with a female connector. Both the male and female connectors have annular grooves on their outer circumferential surfaces. A circular connecting component is engaged in the annular groove. The inner end face of each connecting component is integrally provided with several engaging protrusions. A dustproof ring is provided between the two connecting components. The end face of the dustproof ring has a groove that mates with the engaging protrusions. The two end faces of the dustproof ring respectively abut against the inner end faces of the two connecting components.

[0007] As a preferred embodiment, the connecting assembly includes two annular connecting rings, each with an annular protrusion integrally formed on its inner circumferential surface to fit an annular groove, and both free ends of the connecting rings are provided with connecting flanges, with the connecting flanges of the two connecting rings correspondingly connected.

[0008] As a preferred embodiment, the free end of the snap-fit ​​protrusion is provided with a wedge-shaped limiting section, and the outer circumferential surface of the dustproof ring is provided with a limiting groove that communicates with the bottom of the snap-fit ​​groove. When the snap-fit ​​protrusion engages with the snap-fit ​​groove, the limiting section is located in the limiting groove.

[0009] As a preferred embodiment, the outer circumferential surface of the connecting ring is provided with a plurality of ear plates, and the corresponding ear plates of each connecting ring are arranged on the same axis.

[0010] As a preferred embodiment, both the connecting component and the dust seal are plastic parts.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. Due to the coordinated design of the connecting components and the dustproof ring, when the male and female connectors of the audio cable are connected, the interaction between the snap-fit ​​protrusions and the slots increases the resistance required for the male and female connectors to detach, reducing the possibility of the connectors falling off.

[0013] 2. The two circular connecting rings in the connecting assembly make the entire device have an assembled structure, which is convenient for carrying and installation;

[0014] 3. The dustproof ring not only works in conjunction with the connecting components, but also forms a ring-shaped protective cover at the connection between the male and female connectors to prevent dust accumulation. This device is suitable for industrial production and has strong practicality. Attached Figure Description

[0019] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-3 As shown, an anti-loosening audio cable includes a cable body 1. One end of the cable body 1 is provided with a male connector 2, and the other end is provided with a female connector 3. Both the male connector 2 and the female connector 3 have annular grooves 5 on their outer circumferential surfaces. A circular connecting component 4 is snapped into the annular groove 5. Several snap-fit ​​protrusions 6 are integrally provided on the inner end face of the connecting component 4. A dustproof ring 7 is provided between the two connecting components 4. The end face of the dustproof ring 7 has a groove 701 that mates with the snap-fit ​​protrusions 6. The two end faces of the dustproof ring 7 respectively abut against the inner end faces of the two connecting components 4. The connecting component 4 includes two annular connecting rings 401. An annular protrusion 402, adapted to the annular groove 5, is integrally formed on the inner circumferential surface of each connecting ring 401. Connecting flanges 403 are provided at both free ends of the connecting rings 401, and the connecting flanges 403 of the two connecting rings 401 are connected accordingly. The connection method here is achieved by countersunk holes within the connecting flanges 403, ensuring that the fasteners are not exposed after connection. A wedge-shaped limiting section 601 is provided at the free end of the snap-fit ​​protrusion 6. A limiting groove 702, communicating with the bottom of the snap-fit ​​groove 701, is provided on the outer circumferential surface of the dustproof ring 7. When the snap-fit ​​protrusion 6 engages with the snap-fit ​​groove 701, the limiting section 601 is positioned within the limiting groove 702. Several ear plates 404 are provided on the outer circumferential surface of the connecting rings 401. The corresponding ear plates 404 of each connecting ring 401 are arranged on the same axis, and the corresponding ear plates 404 can be laterally connected and fixed by means of tie rods or other methods. Both the connecting component 4 and the dustproof ring 7 are plastic parts.

[0021] During operation, the operator uses the annular protrusion 402 as a reference line to determine the horizontal position of the two connecting rings 401 of the connecting component 4 with the annular groove 5 on the wire body 1. After completion, the connecting flange 403 of the connecting ring 401 is screwed into the countersunk hole with fasteners to fix the two connecting rings 401. After fixing, the dustproof ring 7 is moved along the axis of the wire body 1 toward the connecting component 4 so that the snap-fit ​​protrusion 6 is inserted into the snap-fit ​​groove 701. At the same time, the other end of the wire body 1 is fixed in the same way, thus completing the connection between the connecting component 4 and the dustproof ring 7 and the wire body 1.

[0022] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
