[0002] As a key interface for audio signal transmission in electronic devices, the audio female connector is widely used in various audio devices such as mobile phones, computers, speakers, and headphones. Its function is to provide a stable electrical connection and ensure that audio signals are transmitted accurately between devices.

[0003] However, current audio connectors commonly use a method of clamping the springs between two shells in production applications. While this design simplifies the assembly process to some extent, it gradually reveals numerous problems as the number of springs increases. Firstly, the installation process becomes complex and time-consuming, significantly increasing the difficulty of aligning the upper and lower shells, easily leading to spring misalignment and tilting, affecting the transmission quality of audio signals. Secondly, the uneven stress distribution on the shells is further exacerbated by frequent plugging and unplugging of audio connectors, resulting in poor structural stability, easy deformation or cracking of the shells, and shortened lifespan of the audio connector. Furthermore, maintenance difficulties and low production efficiency are also significant issues. Disassembling the shells to repair the springs can easily damage other components and requires high-level assembly techniques, increasing costs. Utility Model Content

Detailed Implementation

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1-6As shown, this embodiment provides an audio connector, including a connector body and several spring pieces 3. The bottom of the connector body is provided with several spring piece limiting and fixing slots 4 corresponding to the spring pieces 3. The spring pieces 3 and the spring piece limiting and fixing slots 4 are inserted and engaged. The technical solution of this embodiment creatively solves the problem of inconvenient installation caused by the original method of clamping and fixing the spring pieces with two shells when the number of spring pieces increases. Its core lies in the design of the insertion and engagement between the connector body and the spring pieces, which realizes an efficient and convenient assembly structure. Specifically, the bottom of the connector body is provided with several spring piece limiting and fixing slots that precisely correspond to the number and position of the spring pieces. These spring piece limiting and fixing slots serve as installation guides and fixing structures for the spring pieces, replacing the fixing method of clamping the upper and lower shells in the traditional solution. During assembly, the spring pieces only need to be directly inserted into the corresponding spring piece limiting and fixing slots to complete the positioning and fixing, without the need for additional clamping or pressing operations, which significantly simplifies the assembly process. Each spring, as an independent conductive contact component, is precisely positioned by the spring-limiting and fixing groove, ensuring a stable connection with the socket body and guaranteeing reliable electrical conductivity. Simultaneously, the socket body, as the overall support structure, provides a robust mounting foundation for the springs through its spring-limiting and fixing groove design. Furthermore, its rational layout and dimensional design ensure the orderly arrangement of multiple springs within a limited space, avoiding installation interference or space constraints caused by an increase in the number of springs. Therefore, this technical solution, through the plug-in mating design between the socket body and the springs, fundamentally solves the installation inconvenience problem faced by traditional solutions when the number of springs increases, improving production efficiency, reducing manufacturing costs, and providing strong technical support for the large-scale production and application of audio sockets.

[0029] Preferably, the female connector body includes a tube 1 and a base 2, which are embedded and fitted together to form the female connector body. On one hand, this split design makes the manufacturing process of the female connector body more flexible; the tube and base can be processed using materials and processes suitable for their respective structural and performance requirements, reducing overall manufacturing difficulty and cost. On the other hand, the embedded fit facilitates the subsequent assembly and maintenance of the spring clips. During installation, the female connector body can be assembled simply by precisely aligning and embedding the tube and base, making the operation simple and efficient. If any component is damaged, it can be easily disassembled and replaced without the need for complete scrapping, greatly reducing maintenance costs and improving the maintainability and service life of the product. It should be noted that the embedded fit between the tube 1 and the base 2 can be fixed by means of snap-fit, adhesive, riveting, etc.

[0030] Preferably, the base 2 has a snap-fit ​​protrusion 21 on its side, and the inner wall of the tube 1 has a slot 11 that matches the snap-fit ​​protrusion 21, allowing the base 2 and the tube 1 to snap together. This snap-fit ​​connection is simple in structure and reliable in connection. The precise fit between the snap-fit ​​protrusion and the slot ensures that the tube and base form a stable overall structure after assembly, effectively preventing loosening or separation during use and guaranteeing the electrical connection stability and mechanical strength of the audio connector. Furthermore, the snap-fit ​​connection facilitates quick assembly and disassembly, improving assembly efficiency and reducing labor costs during production. During maintenance, it also allows technicians to quickly disassemble the tube for troubleshooting and component replacement.

[0031] Preferably, the spring 3 includes a first spring 31 and a second spring 32. There are two first springs 31 arranged symmetrically at the center, and each first spring 31 has a concave structure 311. This preferred design subdivides the springs, dividing them into two types: first springs and second springs. The two first springs arranged symmetrically at the center, along with the concave structure, offer significant application advantages. The symmetrical arrangement of the first springs ensures more even force distribution when the audio female connector is plugged in, preventing deformation or damage due to uneven force and improving product reliability and lifespan. The concave structure provides precise positioning and limiting. When the audio female connector mates with the audio male connector, the concave structure fits tightly with the corresponding structure of the male connector, preventing the springs from shifting or wobbling during insertion and removal, ensuring the stability and consistency of the electrical connection. Furthermore, one of the first springs can be replaced as the second spring according to actual needs, providing an additional level of connection for the audio female connector product.

[0032] Preferably, the spring retaining groove 4 includes a first spring retaining groove 41 and a second spring retaining groove 42. The first spring 31 is inserted into the first spring retaining groove 41, and the second spring retaining groove 42 is disposed in the base 2, with the second spring 32 also inserted into the second spring retaining groove 42. This detailed design allows for targeted optimization of the structure and dimensions of the spring retaining groove according to the different characteristics and functional requirements of the springs. For example, for a first spring requiring higher conductivity, a matching first spring retaining groove can be designed to ensure good electrical contact; for a second spring with specific functional requirements, the second spring retaining groove can provide corresponding installation space and positioning structure. This design enables the audio socket to better adapt to the insertion requirements of different types of audio plugs, improving product compatibility and versatility. Furthermore, a chamfered structure is provided on one inner end of the second spring retaining groove 42. The chamfered structure facilitates easier installation when inserting the spring.

[0033] Preferably, the first spring clip limiting and fixing groove 41 is formed by assembling the tube body 1 and the base 2. From a manufacturing process perspective, this design simplifies the processing difficulty of individual components. The tube body and base can be better formed, and for some complex spring clip limiting and fixing groove structures, it is easier to achieve high-precision manufacturing requirements by forming them separately and then combining them, thereby improving product quality and production efficiency. During the assembly process, the docking assembly of the tube body and the base can accurately form the first spring clip limiting and fixing groove, ensuring the size and shape of the spring clip limiting and fixing groove, and ensuring that the first spring clip can be smoothly inserted and achieve a good fit, which is especially suitable for products with multiple spring clips.

[0034] Preferably, the second spring contact 32 is provided with a boss structure 321, and the inner wall of the female connector body is provided with a limiting groove 12 that matches the boss structure 321. The boss structure 321 and the limiting groove 12 are engaged. The engagement of the boss structure and the limiting groove provides a more stable installation position for the second spring contact, preventing it from shaking or shifting during insertion and removal, ensuring the stability and reliability of the electrical connection, and improving assembly efficiency and accuracy. In addition, the engagement also provides a certain buffering effect, reducing direct damage to the second spring contact when subjected to external impact, and extending the service life of the spring contact. Therefore, this technical solution improves the performance and reliability of the audio female connector in multiple aspects and is a further preferred solution.

[0035] Preferably, the number of spring contacts 3 is two to six. From the perspective of audio transmission performance, different numbers of spring contacts can meet the transmission requirements of different types of audio signals. For example, for simple audio transmission, two spring contacts may be sufficient, reducing costs and structural complexity; while for applications requiring high audio quality and multi-channel audio signal transmission, six spring contacts can provide more contact points, ensuring stable audio signal transmission. From the perspective of product manufacturing and assembly, the range of two to six spring contacts, while ensuring product performance, makes the installation and fixing of the spring contacts more convenient and feasible, avoiding installation difficulties and space congestion caused by an excessive number of spring contacts, and also facilitating quality control and inspection. In this embodiment, the number of spring contacts 3 is six.

[0036] Preferably, the device also includes a cap 5, which has a cap opening 51 for positioning. One end of the cap 5 engages with the other end of the female connector body. The cap opening provides double positioning for the male audio connector, ensuring proper insertion and positioning without misalignment. The cap primarily serves to secure the male audio connector, enhance aesthetics, and facilitate cooperation with external components.

[0037] Preferably, the material of the spring 3 is one of brass, tellurium copper, copper, oxygen-free copper, pure silver, or pure gold. These materials not only possess excellent electrical conductivity and corrosion resistance but also maintain stable electrical performance over long-term use. Simultaneously, these materials also exhibit good mechanical strength and machinability, ensuring high precision and durability of the insertion electrode during manufacturing and use. This material selection not only improves the transmission efficiency and signal quality of the audio connector but also provides strong support for its application in various complex environments. Furthermore, the selection of different materials can be flexibly adjusted according to specific application scenarios and requirements to meet users' pursuit of a high-quality audio experience. In this embodiment, copper is used.
