Description

Technical Field

[0001] This utility model relates to the field of communication technology, and in particular to an audio male connector. Background Technology

[0002] As a core component of audio connectors, male audio connectors are widely used in headphones, microphones, and audio equipment. Their typical structure includes a metal housing, insulator, terminal contacts, and tail terminals, requiring a balance of conductivity, abrasion resistance, and structural stability to meet high-frequency mating requirements. However, current production of male audio connectors generally employs a "segmented collaboration" model: specialized connector manufacturers are responsible for core processes such as stamping the metal electrodes and injection molding the insulator, creating semi-finished products that are then delivered to end-product manufacturers for wire bonding (soldering the wires to the terminals) and secondary encapsulation (fixing the wires and enhancing structural strength). The secondary encapsulation used by end-product manufacturers results in low production efficiency and high costs. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the technical problem to be solved by this utility model is to propose an audio male connector that can solve the production problem of low manufacturing efficiency caused by the connection of the latter half of the audio male connector by the product manufacturer through overmolding.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] This utility model provides an audio male connector, including a female connector and a wire bonding connector, which are electrically connected. An insulating seat is provided between the female connector and the wire bonding connector, and the insulating seat has a threaded structure for threaded connection with the end product.

[0006] The preferred technical solution of this utility model is that the thread structure is an external thread.

[0007] The preferred technical solution of this utility model is that a breaking structure is provided on the external thread.

[0008] A preferred embodiment of this invention is that a limiting part is provided on one side of the insulating base located at the female connector.

[0009] The preferred technical solution of this utility model is that the female connector includes a plurality of female connector contacts, and the wire bonding connector includes a plurality of wire bonding contacts corresponding to the female connector contacts, and the female connector contacts and the corresponding wire bonding contacts are electrically connected.

[0010] The preferred technical solution of this utility model is that the female contact electrode and the bonding wire contact electrode have a ring-shaped structure.

[0013] The preferred technical solution of this utility model is that the insulating base and the insulating part are made of one of liquid crystal polymer, ABS and nylon.

[0014] The preferred technical solution of this utility model is that the material of the female connector and the wire bonding connector is one of brass, tellurium copper, copper, oxygen-free copper, pure silver, and pure gold.

[0015] The beneficial effects of this utility model are:

[0016] This invention proposes an audio male connector where the female connector and the wire bonding connector are integrated into a complete electrical path for signal transmission.

Detailed Implementation

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-8 As shown in this embodiment, an audio male connector includes a female connector 1 and a wire bonding connector 2. The female connector 1 and the wire bonding connector 2 are electrically connected. An insulating seat 3 is provided between the female connector 1 and the wire bonding connector 2. The insulating seat 3 has a threaded structure for threaded connection with the end product. In the existing production mode, the wire bonding connector of the latter half of the audio male connector needs to be encapsulated and injection molded by the manufacturer responsible for the end product to complete the connection of the product. This results in a longer production cycle, and the internal structure of the injection mold, including the wire bonding, increases the difficulty of quality control. The technical solution of this embodiment integrates the female connector and the wire bonding connector into a complete electrical path to realize signal transmission. The female connector is used to insert into the female connector to connect with it, while the wire bonding connector undertakes the subsequent wire welding and external cable splicing functions. The two are electrically isolated and structurally supported by the insulating seat. This insulating seat not only blocks current to avoid short circuit risk, but also innovatively introduces a threaded structure as the connection interface of the end product. This design allows end-user manufacturers to quickly assemble the audio male connector portion of their products simply by screwing it on after receiving the component, completely eliminating the time-consuming steps of mold replacement and secondary curing involved in traditional overmolding processes. The standardized threaded structure further enhances product compatibility, accommodating various sizes of mounting holes in end-user devices. While ensuring electrical performance, it significantly improves production efficiency and effectively reduces yield losses caused by injection molding, fully demonstrating a systematic technological breakthrough from structural innovation and process optimization.

[0030] Preferably, the thread structure is an external thread 4. 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 male 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.

[0031] Preferably, the external thread 4 is provided with a break structure 5. 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.

[0032] Preferably, a limiting part 6 is provided on one side of the female connector 1 on the insulating base 3. Different terminal devices have different requirements for the screw-in depth of the audio male connector. If it is screwed in too shallowly, it may cause poor contact between the audio male 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 male 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.

[0033] Preferably, the female connector 1 includes several female connector contacts, and the wire bonding connector 2 includes several wire bonding contacts corresponding to the female connector contacts. The female connector contacts and their corresponding wire bonding contacts are electrically connected. From the perspective of signal transmission integrity, the one-to-one electrical connection between multiple female connector contacts and their corresponding wire bonding contacts ensures that each channel of the audio signal is transmitted independently and stably. In the audio field, different channels (such as left channel, right channel) and possible grounding and control signals need to be transmitted through their respective channels. Each female connector contact is responsible for receiving a specific signal from the audio female connector and transmitting the signal to the external cable through its corresponding wire bonding contact, avoiding mutual interference and crosstalk between signals and ensuring high-fidelity transmission of the audio signal. From the perspective of functional scalability, this design adds more functional possibilities to the audio male connector. For example, with the development of audio technology, it may be necessary to add new signal channels or functional modules in the future. The existing multi-contact design provides the hardware foundation for these expansions. New functions can be integrated simply by making corresponding adjustments at the software and protocol levels, without requiring large-scale modifications to the physical structure of the audio male connector. From the perspective of production consistency, standardized contact electrode correspondence facilitates quality control and inspection during the production process. In this embodiment, four sets of female connector contacts and corresponding bonding wire contacts are provided. The female connector connection part 1 includes a first female connector contact 11, a second female connector contact 12, a third female connector contact 13, and a fourth female connector contact 14. Correspondingly, the bonding wire connection part 2 includes a first bonding wire contact 21, a second bonding wire contact 22, a third bonding wire contact 23, and a fourth bonding wire contact 24.

[0034] Preferably, the female connector contact and the solder wire contact are in a toroidal structure. From the perspective of contact reliability, the toroidal structure increases the contact area. When the audio male connector is connected to the audio female connector, and when the solder wire contact is connected to the external cable, the larger contact area means a more stable electrical connection. Compared with other contact shapes, the toroidal structure can fully contact the mating parts in all directions, reducing problems such as increased resistance and overheating caused by poor contact, thus ensuring high-quality transmission of audio signals. From the perspective of wear resistance and durability, the toroidal structure can better distribute stress during long-term use. When the audio male connector is frequently plugged in and out or subjected to external forces, the uniform stress characteristics of the toroidal structure can avoid local stress concentration, reduce wear and deformation of the contact, and extend the service life of the audio male connector. From the perspective of installation adaptability, the toroidal structure has relatively low requirements for installation angle and position. Regardless of the angle at which the audio female connector or the external cable connection parts contact the audio male connector, the toroidal structure can guarantee a certain contact area, improving the convenience and flexibility of installation and reducing contact problems caused by improper installation.

[0035] Preferably, an insulating portion 7 is provided between adjacent female connector contacts and between adjacent solder wire contacts, and the insulating portion 7 has a toroidal structure. From the perspective of electrical insulation performance, the insulating portion between adjacent contacts can effectively prevent interference and short circuits between signals. During audio signal transmission, different contacts carry signals with different potentials or functions. Without the isolation of the insulating portion, crosstalk may occur between adjacent contacts due to minor electrical leakage or external interference, resulting in audio signal distortion. The toroidal insulating portion can completely surround adjacent contacts, providing reliable electrical isolation, ensuring that the signal on each contact is transmitted independently, and improving the quality of the audio signal. From the perspective of structural stability, the toroidal insulating portion can play a certain supporting and fixing role. It can enhance the structural strength between contacts, prevent the contacts from shifting or deforming due to external forces during use, and maintain the stability of the internal structure of the audio male connector.

[0036] Preferably, the insulating base 3 and the insulating part 7 are integrally formed. From an electrical performance perspective, the integrally formed structure eliminates the assembly gap between the insulating base and the insulating part. In audio signal transmission, even tiny gaps can lead to a decrease in electrical performance, such as the generation of parasitic capacitance and inductance, affecting the signal transmission quality. Integral forming ensures the continuity and integrity of the insulating part, providing a more stable and reliable electrical insulation environment and reducing the possibility of signal leakage and interference. From a structural strength perspective, integral forming makes the insulating base and the insulating part a whole, greatly enhancing the strength of the entire insulation structure.

[0037] Preferably, the insulating base 3 and the insulating part 7 are made of one of liquid crystal polymer, ABS, and nylon. From the perspective of electrical insulation performance, all three materials have excellent insulation properties. Liquid crystal polymer has extremely low dielectric constant and dielectric loss, which can effectively reduce energy loss and distortion during signal transmission, making it particularly suitable for applications with high requirements for audio signal quality. ABS material has good insulation and electrical stability, maintaining stable insulation performance under different environmental conditions, meeting the usage requirements of general audio equipment. Nylon material also has excellent insulation performance, and its insulation performance remains relatively stable even in harsh environments such as humidity, providing reliable electrical protection for the audio male connector. From the perspective of mechanical properties, they all have a certain degree of strength and toughness. Liquid crystal polymer has high strength and high modulus, capable of withstanding large external forces without deformation or damage, ensuring the structural stability of the audio male connector during insertion, removal, and use. ABS material has good toughness and impact resistance, effectively buffering external impact forces and protecting internal electrical connection components. Nylon material possesses 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 male connector. From a processing perspective, all three materials are easily molded using common processing techniques such as injection molding. They exhibit good flowability, enabling them to fill complex mold structures. In this embodiment, the insulating base 3 and the insulating portion 7 are made of liquid crystal polymer.

[0038] Preferably, the materials for the female connector 1 and the wire bonding connector 2 are one of brass, tellurium copper, copper, oxygen-free copper, pure silver, and pure gold. These materials not only have excellent electrical conductivity and corrosion resistance, but also maintain stable electrical performance during long-term use. Simultaneously, these materials also possess 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 male 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.

[0039] The manufacturing process for the above-mentioned male audio connector is as follows:

[0040] First, the female connector contact and its corresponding bonding wire contact are processed into a single integral component, omitting the additional electrical connection process between the two. The first female connector contact 11 and the first bonding wire contact 21 are integrally formed into a first integral component through metal processing. Similarly, the second female connector contact 12 and the second bonding wire contact 22 are integrally formed into a second integral component through metal processing. The third female connector contact 13 and the third bonding wire contact 23 are integrally formed into a third integral component through metal processing. The fourth female connector contact 14 and the fourth bonding wire contact 24 are integrally formed into a fourth integral component through metal processing.

[0041] Then, the various integral parts mentioned above are arranged in the mold according to the design structure, and then formed into a continuous structure with an insulating base 3, external thread 4, insulating part 7, and limiting part 6 by injection molding. This ultimately yields the desired audio male connector product.

[0042] It should be noted that this male connector can be used not only in the field of audio communication, but also in the medical and aerospace fields where multiple signals need to be transmitted, in order to improve the stability of signal transmission.
