Abstract
Description
Technical Field
[0001] This utility model relates to the field of communication technology, and in particular to an audio female connector. Background Technology
[0002] An audio female connector is a connector interface used for audio signal transmission, widely used in various audio devices such as speakers, headphones, power amplifiers, and mixing consoles. It typically consists of a metal housing, insulating material, and internal conductive contacts. Its function is to provide a stable and reliable electrical connection for audio signals, ensuring efficient and accurate transmission between different devices, thereby enabling audio playback, recording, and processing functions.
[0003] In the manufacturing process of audio connectors, the handling of the wire bonding section has a significant impact on production efficiency and product quality. Currently, many manufacturers use overmolding to connect the wire bonding portion of the audio connector. Specifically, this involves first soldering the various pins of the audio connector to the wires, then placing the soldered component into a mold, and finally using injection molding to encapsulate the soldered area with plastic material, providing fixation, insulation, and protection. However, this overmolding method easily leads to low manufacturing efficiency, mainly in the following aspects: Complex process flow: Overmolding involves multiple steps, including welding, mold preparation, injection molding, cooling, and demolding. Long production cycle: Because overmolding requires multiple steps, and each step takes time to complete, the overall production cycle is long. Difficulty in guaranteeing quality stability: During the overmolding process, various factors such as mold precision, injection parameters, and plastic material properties can easily lead to unstable product quality.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0027] like Figure 1-5 As shown, this embodiment provides an audio connector, including a housing 1 and several spring contacts 2. The spring contacts 2 are installed on the housing 1, and the housing 1 has a threaded structure for threaded connection with the end product. In current audio connector production, it is common practice to first complete semi-finished components, and then hand over the parts requiring wire bonding to the product manufacturer for encapsulation and injection molding. However, this mode suffers from low production efficiency and inconvenience. The technical solution of this embodiment uses the housing as the basic support structure of the entire audio connector, which plays a role in shaping and protecting the internal components. The additional threaded structure on the housing allows the audio connector to be directly and securely installed with the end product through threaded connection, eliminating the need for complex connection methods such as injection molding. The entire audio connector component enters the subsequent production stage as a relatively complete component, effectively avoiding the time loss and quality risks caused by step-by-step production and multi-stage connection. This optimizes the overall production process, significantly improves production efficiency, and solves the problems of low efficiency and inconvenience of traditional production methods.
[0028] Preferably, the thread structure is an external thread 3. Firstly, from an installation compatibility perspective, the external thread structure has broader compatibility in end-product applications. Currently, many audio devices and electronic products on the market tend to use internal thread mounting holes in their interface designs. External thread audio female connectors can be directly screwed into these standard interfaces without the need for additional adapters, greatly improving product versatility. Secondly, in the manufacturing process, the machining technology for external threads is relatively mature and cost-effective. Compared to internal threads, external threads can be efficiently machined using conventional processes such as turning and rolling, with easily controllable precision. This ensures that parameters such as pitch and tooth profile are consistent for each thread, thereby guaranteeing a tight and stable connection with the end product.
[0029] Preferably, the external thread 3 is provided with a break structure 4. In mold design, the determination of the parting surface is crucial, directly affecting the manufacturing difficulty and cost of the mold. When the external thread lacks a break structure, the parting surface of the mold needs to extend complexly along the helix of the thread to complete the thread formation. This not only increases the complexity of the mold design but may also lead to defects such as burrs and flash at the parting surface. The presence of the break structure provides a certain margin of error in mold processing. During mold processing, since the thread at the break structure does not need to be completely continuous, the requirements for machining accuracy can be appropriately reduced. The mold can be rationally parted at the break structure, making the parting surface simpler and more regular.
[0030] Preferably, a limiting part 5 is provided on one side of the front end of the housing 1. Different terminal devices have different requirements for the screw-in depth of the audio female connector. If it is screwed in too shallowly, it may cause poor contact between the audio female connector and the terminal device, affecting the transmission quality of the audio signal; if it is screwed in too deeply, it may damage the internal components or structure of the terminal device. The limiting part is like a precise "ruler". When the audio female connector is screwed in to a certain depth, the limiting part will contact the corresponding part of the terminal device and prevent it from being screwed in further, thereby accurately controlling the screw-in depth and ensuring the stability and reliability of the installation.
[0031] Preferably, the limiting part 5 has a ring-shaped structure, and the limiting part 5 is provided with an anti-slip groove 51. The ring-shaped limiting part can provide uniform support and positioning during installation. The anti-slip groove is designed to solve the problem of applying force during installation. During threaded connection, the user needs to apply a certain rotational force to install the audio female connector in place. The anti-slip groove increases the friction between the hand and the limiting part, making it easier for the user to apply force when rotating the audio female connector.
[0032] Preferably, the inner wall of the housing 1 is provided with several fixing slots 6 for fixing and matching the spring 2. From the perspective of spring fixing stability, the fixing slots provide a precise installation position for the spring, ensuring that the spring is firmly fixed within the housing and will not shift due to external forces or equipment vibration. During audio signal transmission, the spring needs to maintain stable contact with the audio plug. If the spring shifts, it may lead to poor contact, affecting the quality of the audio signal and causing problems such as noise and dropouts. The existence of the fixing slots effectively avoids this situation, ensuring the stability and reliability of audio signal transmission. From the perspective of production assembly efficiency, the design of the fixing slots makes the installation of the spring simpler and faster. During production, workers only need to accurately place the spring into the corresponding fixing slot to complete the installation of the spring, without the need for complex adjustments and fixing operations, significantly shortening the production cycle and improving production efficiency.
[0033] Preferably, the housing 1 includes a tube 11 and a base 12, which are fitted together to form the housing 1. From a manufacturing perspective, this split design makes the production process more flexible. The tube and base can be produced using different processing techniques, and the most suitable processing method can be selected according to their respective structural characteristics and performance requirements, thereby improving production efficiency and product quality. For example, the tube may require more attention to appearance precision and surface treatment, while the base may require stronger structural strength. Split production can better meet these different needs. From the perspective of installation and maintenance convenience, the fitted design of the tube and base makes the installation and disassembly of the audio connector more convenient. During installation, assembly can be completed simply by accurately fitting the tube and base together, without complicated operating steps. Specifically, in order to facilitate the extension of the spring 2, several corresponding openings 122 are provided on the base 12, and one end of the spring 2 extends out of the housing through the openings 122.
[0034] Preferably, the base 12 has an outwardly protruding force-applying part 121. From the perspective of ease of installation, the force-applying part provides a clear point of application for installing the base. When installing the base to the bottom of the tube, the user can apply appropriate force by holding the force-applying part, so that the base can be more accurately and easily embedded into the tube.
[0035] Preferably, the tube body 11 and the base 12 are integrally molded by injection molding. During injection molding, the entire structure of the tube body or base can be manufactured in one step, eliminating the need for assembling and connecting multiple parts, significantly shortening the production cycle and improving production efficiency. Simultaneously, the injection molding process has a high degree of automation, reducing manual intervention and labor costs, further improving the economics of production. From a product quality perspective, integral injection molding ensures the structural integrity and precision of the tube body and base. Because the entire component is molded in one piece, there are no issues such as seams or gaps caused by assembly.
[0036] Preferably, the tube body 11 and the base 12 are made of one of liquid crystal polymer, ABS, and nylon. From an electrical insulation perspective, all three materials possess excellent insulation properties. Liquid crystal polymers have extremely low dielectric constants and dielectric losses, effectively reducing energy loss and distortion during signal transmission, making them particularly suitable for applications with high audio signal quality requirements. ABS material has good insulation and electrical stability, maintaining stable insulation performance under various environmental conditions, meeting the needs of general audio equipment. Nylon material also possesses excellent insulation properties, and its insulation performance remains relatively stable even in harsh environments such as humid conditions, providing reliable electrical protection for the audio connector. From a mechanical perspective, they all possess certain strength and toughness. Liquid crystal polymers have high strength and high modulus, capable of withstanding significant external forces without deformation or damage, ensuring the structural stability of the audio connector during insertion, removal, and use. ABS material has good toughness and impact resistance, effectively buffering external impacts and protecting internal electrical connection components. Nylon materials possess high wear resistance and self-lubricating properties, reducing wear between the connector and mating parts during frequent insertion and removal, thus extending the lifespan of the audio connector. From a processing perspective, all three materials are easily molded using common processes such as injection molding. They exhibit good flowability, enabling them to fill complex mold structures. In this embodiment, a liquid crystal polymer is used.
[0037] Preferably, the number of spring contacts 2 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 2 is six.
[0038] Preferably, the material of the spring 2 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.
