Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a miniaturized multi-core circular waterproof connector. Background Technology

[0002] In the current development of electronic devices, the demand for miniaturization, integration, and adaptability to complex environments is growing exponentially. Whether it's the pursuit of ultra-thin and multi-functional integration in portable electronic devices, or the desire for miniaturized devices with highly reliable connections in fields such as industrial automation, the Internet of Things, and medical equipment, miniaturized, multi-core waterproof connectors have become a key technological milestone. However, existing connector products on the market struggle to simultaneously meet these three key indicators: miniaturization, multi-core count, and reliable waterproofing.

[0003] The current field of miniature circular connectors is facing a significant technical contradiction: existing products either meet the form factor requirement of "miniaturization" but have obvious shortcomings in waterproof performance; or they achieve effective waterproof protection but have to sacrifice compactness or reduce the number of cores, making it difficult to meet multi-dimensional performance requirements. Specifically, mainstream small circular connectors on the market generally adopt open or simple dustproof designs to achieve a compact structure, with basic mating gaps at the joints and a lack of dedicated waterproof structures. These products are highly susceptible to moisture intrusion in humid environments. When used in outdoor equipment, industrial automation, or water-related scenarios in consumer electronics, they often experience signal transmission abnormalities or even short circuits within a short period due to a drop in insulation resistance. Conversely, waterproof circular connectors face a design dilemma between size and core count. Therefore, the current market urgently needs a miniaturized, high-core, and reliably waterproof connector.

[0004] Therefore, we propose a miniaturized, multi-core circular waterproof connector to solve the above problems. Utility Model Content

[0014] (III) Beneficial Effects: Compared with the prior art, this utility model provides a miniaturized multi-core circular waterproof connector, which has the following beneficial effects: 1. Through its overall design, this utility model offers the following advantages: Breaking through technical contradictions and achieving synergistic balance of multiple performance aspects: The overall design breaks through the bottleneck of the incompatibility between miniaturization, high core count, and reliable waterproofing in existing technologies, achieving an organic unity of the three without sacrificing any core performance; it gets rid of the dilemma of traditional design between size, core count, and protection capability, allowing the connector to maintain a compact form to adapt to the miniaturization requirements of equipment, support multi-functional integration with sufficient core count, and cope with complex and humid environments with reliable waterproof characteristics, fully meeting multi-dimensional usage needs; Expanding application scenarios and adapting to diverse device needs: This design can accurately match the usage scenarios of multiple fields such as portable electronic devices, industrial automation, IoT, and medical devices. For portable products that pursue extreme thinness and multi-functional integration, its miniaturization and multi-core characteristics can help devices integrate more functions without taking up too much space; for devices used in outdoor operations, water immersion, or humid industrial environments, reliable waterproof performance can ensure stable operation of the connector, no longer limited by the usage environment, and greatly expanding the application range of the connector; Improve reliability and reduce equipment failure risk: Through a specialized structure and the design of O-rings and sealing gaskets, the system effectively blocks the path of moisture intrusion, avoiding the insulation resistance reduction problem that is prone to occur in traditional open or simple dustproof designs; it not only ensures the stability and accuracy of signal transmission, but also prevents faults such as short circuits, reduces equipment repair and replacement costs due to connector failure, extends the overall service life of the equipment, and improves the user experience.

[0015] 2. The structural disassembly and assembly design of this utility model can bring the following benefits to the overall operation: Improving structural fit accuracy and enhancing core performance stability: Independent mold making and processing of internal and external structural components ensure that the dimensional accuracy and shape details of each component can accurately match the design requirements; the assembly fit between structural components is greatly improved, effectively reducing the gap between them, which not only provides a more compact space basis for miniaturized layout, but also further enhances the waterproof sealing effect through tight structural fit, while ensuring the regularity of multi-core arrangement, making the core performance more stable and reliable; Optimizing production and assembly efficiency and ensuring batch consistency: Independently designed molded and machined parts can form a standardized production process, and the production process of each component can be specifically standardized, reducing the adjustment costs when adapting general-purpose parts. During assembly, the connection between various structural components is smoother, without the need for additional grinding or adaptation adjustments. This not only improves assembly efficiency but also reduces the error rate in batch production, ensuring that the performance parameters of each batch of products are consistent and improving the overall quality control level.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0020] Example: Please refer to Figures 1 to 5 As shown: A miniaturized, multi-core circular waterproof connector includes a tail cover A1. One end of the tail cover A1 is threadedly connected to a plug housing 2. The plug housing 2 has an annular groove in which a first O-ring 3 is fitted. A base A4 is inserted and fixedly connected to the plug housing 2. Pins 5 are equidistantly fixedly connected to the base A4, and the tail ends of the pins 5 are connected to a common metal wire A6. A connecting ring 7 is fitted onto the plug housing 2. An inner retaining ring 8 is fitted into another annular groove on the plug housing 2, located between the plug housing 2 and the connecting ring 7. A recessed groove is formed on the top of the plug housing 2, and a sealing gasket 9 is embedded in the recessed groove. 2 and connecting ring 7 form an integral part. The exposed part of the integral part forms a mating ring groove 10. A tail cover B11 is provided on one side of the connecting ring 7. One end of the tail cover B11 is threaded to a socket housing 12. A ring groove is provided on the socket housing 12. A second O-ring 13 is fitted in the ring groove. The second O-ring 13 is located between the tail cover B11 and the socket housing 12. A base B14 is inserted and fixedly connected inside the socket housing 12. Insert shell holes 15 are fixedly connected at equal intervals on the base B14. A metal wire B16 is fixedly connected to the tail end of the insert shell holes 15. The inner cavity of the socket housing 12 is blocked by the outer end of the base B14 to form a mating interface 17.

[0021] in: Both tail cover A1 and tail cover B11 are potted to meet the waterproof requirements of the connector.

[0022] The pin 5 and the rigid housing hole 15 together constitute the contact element; both use high-quality copper alloy as the base material, which can provide a good basic channel for current transmission. On this basis, a uniform and dense gold layer is formed on the surface of the copper alloy through a precise gold plating process; In terms of contact resistance control, the gold plating layer has extremely low resistivity, which can effectively reduce contact resistance during current transmission. In terms of corrosion resistance, gold with a gold plating layer has extremely strong chemical stability and is not easily reacted with oxygen, moisture and other corrosive media in the air. In terms of wear resistance, the gold plating layer has good hardness and wear resistance, which can effectively resist mechanical wear of the contacts during insertion and removal.

[0023] Except for the contact parts, all other metal components are made of stainless steel with high strength and toughness, capable of withstanding certain mechanical impacts and vibrations, ensuring the structural stability of the product. During product assembly and use, the metal components can withstand various external forces, effectively preventing deformation, breakage, and other problems, thus ensuring the overall performance and safety of the product.

[0024] The sealing gasket 9 is made of fluorosilicone rubber to ensure waterproof performance in harsh environments.

[0025] The connector in this design has two types of connector bases, which can be referred to in the appendix. Figure 1 With appendix Figure 2 Apart from slight differences in form, the working process is the same, so this document only describes one of them.

[0026] The plug body is composed of the tail cover A1, plug housing 2, first O-ring 3, base A4, pin 5, metal wire A6, connecting ring 7, inner retaining ring 8, sealing gasket 9, and mating ring groove 10. The plug body is composed of the tail cover B11, socket housing 12, second O-ring 13, base B14, socket hole 15, metal wire B16, and mating interface 17.

[0027] All internal and external structural components in this design are independently designed molded and machined parts.

[0028] Working principle: When in use, the plug and socket are connected, that is, the socket housing 12 will move and insert into the mating ring groove 10. Then, the two are screwed together to make them mesh. At this time, the mating end face of the socket housing 12 will abut against the sealing gasket 9 in the ring groove of the plug housing 2, thus completing the waterproofing at the connection point. Then, by injecting sealant into the tail cover A1 and tail cover B11, the overall waterproofing of the plug and socket is achieved.

[0029] Please refer to the above work process. Figures 1 to 5 .
