Description

Technical Field

[0001] This application relates to the field of connector technology, and in particular to a coaxial connector and an electronic device. Background Technology

[0002] Coaxial connectors are widely used in electronic devices for signal transmission, especially in applications requiring shielding against electromagnetic interference. Existing coaxial connectors typically consist of a plug assembly and a receiver assembly. The plug assembly connects to the coaxial cable, while the receiver assembly is usually mounted on a circuit board.

[0003] In implementing the embodiments of this application, the inventors discovered that the plug shell of current coaxial connectors is prone to deformation during repeated insertion and removal, especially the metal shell (iron shell) of the plug, which undergoes permanent deformation when mating with the receiving component. This deformation not only reduces the service life of the connector but also leads to unstable connection, reduced pull-out force, and affects the reliability of signal transmission. Utility Model Content

[0004] The main technical problem addressed by this application is to provide a coaxial connector that prevents permanent deformation of the plug housing during mating with the receiver housing, especially in areas subject to high stress. The reinforced plug housing structure effectively improves the connector's pull-out force, ensuring the reliability and stability of signal transmission.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application embodiment is: to provide a coaxial connector, including a plug assembly and a receiving assembly. The plug assembly includes a plug housing, a plug insulator disposed within the plug housing, and a plug conductive terminal disposed within the plug insulator. The receiving assembly includes a receiving housing, a receiving insulator disposed within the receiving housing, and a receiving conductive terminal disposed within the receiving insulator. The circumferential wall of the plug housing has at least one inwardly bent reinforcing structure. The plug conductive terminal is connected via a coaxial cable, and the plug conductive terminal is connected to the receiving conductive terminal. At the same time, the plug housing and the receiving housing are connected to each other.

[0006] Optionally, the reinforcing structure includes a plurality of bends evenly distributed along the circumferential wall of the plug housing, each bend including a bend wall extending inward from the inner surface of the circumferential wall, the bend wall forming an angle with the circumferential wall.

[0007] Optionally, the plug housing is provided with a snap-fit ​​structure, and the receiver housing is provided with a slot structure that cooperates with the snap-fit ​​structure.

[0008] Optionally, one end of the plug housing is provided with a protrusion, and the receiving housing is provided with an annular groove that mates with the protrusion. When the protrusion contacts the annular groove, it forms a positioning feature.

[0009] Optionally, the receiving housing includes a base and a receiving portion, the base being connected to a circuit board, the receiving portion cooperating with the plug housing, and the inner surface of the receiving portion having a plurality of protrusion structures.

[0010] Optionally, the surfaces of the plug housing and the receiver housing are provided with an anti-corrosion coating.

[0011] Optionally, the receiving housing includes at least one solder foot that is connected to the circuit board.

[0012] Optionally, the outer surface of the plug housing is provided with an anti-slip texture.

[0013] Optionally, the edge of the receiver housing that contacts the plug housing has a chamfered structure.

[0014] To solve the above-mentioned technical problems, another technical solution adopted in the embodiments of this application is to provide an electronic device including any of the coaxial connectors mentioned above.

[0015] This application provides a coaxial connector, including a plug assembly and a receiving assembly. The plug assembly includes a plug housing, a plug insulator disposed within the plug housing, and plug conductive terminals disposed within the plug insulator. The receiving assembly includes a receiving housing, a receiving insulator disposed within the receiving housing, and receiving conductive terminals disposed within the receiving insulator. The circumferential wall of the plug housing has at least one inwardly bent reinforcing structure. The plug conductive terminals are connected via a coaxial cable and mate with the receiving conductive terminals. Simultaneously, the plug housing and the receiving housing mate with each other. By providing an inwardly bent reinforcing structure on the circumferential wall of the plug housing, the overall structural rigidity of the plug housing is improved. This reinforcing structure prevents permanent deformation of the plug housing during mating with the receiving housing, especially in areas of high stress. The reinforcing structure effectively improves the connector's pull-out force, ensuring the reliability and stability of signal transmission. Furthermore, this design does not require increasing material thickness or changing overall dimensions, and does not affect the connector's standard specifications or installation space. This structural optimization is simple and easy to implement, suitable for mass production, and can effectively extend the product's service life and reduce the risk of damage during frequent insertion and removal. In addition, the improved structural strength allows the connector to maintain good mechanical performance in harsh environments, meeting the needs of various application scenarios.

[0024] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0025] Please see Figure 1 The coaxial connector 100 includes a plug assembly 10 and a receiver assembly 20.

[0026] Please see Figure 2 and Figure 4 The plug assembly 10 includes a plug housing 11, a plug insulator 12 disposed within the plug housing 11, and plug conductive terminals 13 disposed within the plug insulator 12. To address the problem of easy deformation of the plug housing during insertion and removal in the prior art, this embodiment designs at least one inwardly bent reinforcing structure 30 on the circumferential wall of the plug housing 11. The reinforcing structure 30 is similar to a reinforcing rib, improving the structural rigidity of the plug housing 11 and enhancing its resistance to deformation.

[0027] Please see Figure 3 The receiving assembly 20 includes a receiving housing 21, a receiving insulator 22 disposed inside the receiving housing 21, and a receiving conductive terminal 23 disposed inside the receiving insulator 22. When the coaxial connector 100 is working, the plug conductive terminal 13 is connected to the signal source through the coaxial cable and is connected in conjunction with the receiving conductive terminal 23 to achieve reliable signal transmission; at the same time, the plug housing 11 and the receiving housing 21 are connected in conjunction to form a stable mechanical structure and provide grounding protection.

[0028] In this embodiment, the mechanical stability and service life of the coaxial connector 100 during repeated insertion and removal are improved by setting the reinforcing structure 30, so that the coaxial connector 100 always maintains good electrical connection performance and meets the needs of high reliability application scenarios.

[0029] In some preferred embodiments, the reinforcing structure 30 includes a plurality of bends (not shown) evenly distributed along the circumferential wall of the plug housing. By arranging them evenly in the circumferential direction to ensure balanced structural strength, each bend includes a bend wall extending inward from the inner surface of the circumferential wall and forming an angle with it. This forms an internal reinforcing rib structure, enhancing the overall rigidity of the plug housing 11. This evenly distributed bend design can more effectively disperse stress and reduce local deformation during insertion and removal. Especially during product mating, where permanent deformation of the plug housing often occurs, it can provide additional support at critical locations, significantly reducing the amount of deformation. Compared to a single reinforcing structure 30, the evenly distributed multiple bends provide more comprehensive structural support, improving overall pull-out force while ensuring the structural integrity of the connector during long-term use.

[0030] In some embodiments, the plug housing 11 is provided with a snap-fit ​​structure (not shown), and the receiver housing 21 is provided with a slot structure that mates with the snap-fit ​​structure. When the plug assembly 10 is connected to the receiver assembly 20, the snap-fit ​​structure and the slot structure automatically lock together, ensuring a secure and reliable connection. This design ensures both good electrical connection performance and sufficient mechanical strength to prevent accidental disconnection due to external forces during use. Furthermore, when disassembly is required, the snap-fit ​​can be released simply by applying appropriate force, enabling convenient disassembly.

[0031] In some embodiments, to improve the positioning accuracy and ease of insertion and removal of the coaxial connector 100, a protrusion (not shown) is designed at one end of the plug housing 11. Correspondingly, an annular groove that mates with the protrusion is designed on the receiving housing 21. When the plug assembly 10 is connected to the receiving assembly 20, the protrusion slides into the annular groove, forming a precise positioning that ensures accurate alignment between the terminals, reduces the risk of terminal damage due to misalignment, and improves the reliability of signal transmission. Furthermore, this positioning mechanism provides clear tactile feedback, allowing the user to clearly perceive that the connection is complete.

[0032] Please reconsider. Figure 4 In this embodiment, the receiving housing 21 includes a base 211 and a receiving portion 212. The base 211 is used to connect to the circuit board to ensure a secure mechanical fixation; the receiving portion 212 cooperates with the plug housing 11 to achieve electrical connection. To enhance the reliability of the connection, the inner surface of the receiving portion 212 is also provided with multiple protrusion structures (not shown). These protrusions can increase the contact area with the plug housing 11, improve the contact pressure, and ensure good electrical connection and grounding effect. At the same time, this design also helps to reduce wear during the insertion and removal process and extend the service life of the connector.

[0033] In some embodiments, an anti-corrosion plating (not shown) is provided on the surfaces of the plug housing 11 and the receiver housing 21, which effectively prevents oxidation and corrosion of the metal housing in humid, salty, or corrosive gas environments. The anti-corrosion plating not only protects the appearance of the connector but, more importantly, ensures the stability of its electrical performance during long-term use. By selecting appropriate plating materials and processes, the service life of the connector under various environmental conditions can be significantly extended.

[0034] In some embodiments, for ease of integration with a circuit board, the receiving housing 21 of this embodiment is designed with at least one soldering pin (not shown). These soldering pins can be directly inserted into pre-drilled holes in the circuit board and a secure connection is achieved through reflow soldering or wave soldering processes. The design of the soldering pins takes into account the balance between manufacturing process and mechanical strength, ensuring the reliability of the soldering process while providing sufficient mechanical strength to withstand various stresses in daily use.

[0035] In some embodiments, an anti-slip texture (not shown) is provided on the outer surface of the plug housing 11. This texture increases the surface friction coefficient, providing a better grip for the user during plugging and unplugging operations. The anti-slip texture design considers both aesthetics and functionality, making it particularly suitable for scenarios requiring frequent plugging and unplugging operations or use in special environments (such as when operating with gloves). A carefully designed texture pattern can also give the product a unique visual identity.

[0036] In some embodiments, to improve the smoothness of insertion and removal operations and reduce wear, a chamfered structure (not shown) is provided at the edge where the receiver housing 21 contacts the plug housing 11. The chamfered structure allows the plug to slide more smoothly into the receiver assembly 20 during insertion, reducing jamming and wear. The chamfered structure not only improves the user experience but also extends the connector's lifespan, reducing edge wear and deformation caused by repeated insertion and removal. This seemingly minor design detail plays a crucial role in improving the overall quality and durability of the product.

[0037] This application provides a coaxial connector 100, including a plug assembly 10 and a receiving assembly 20. The plug assembly 10 includes a plug housing 11, a plug insulator 12 disposed within the plug housing 11, and a plug conductive terminal 13 disposed within the plug insulator 12. The receiving assembly 20 includes a receiving housing 21, a receiving insulator 22 disposed within the receiving housing 21, and a receiving conductive terminal 23 disposed within the receiving insulator 22. The circumferential wall of the plug housing 11 has at least one inwardly bent reinforcing structure 30. The plug conductive terminal 13 is connected via a coaxial cable and mates with the receiving conductive terminal 23. Simultaneously, the plug housing 11 and the receiving housing 21 mate with each other. By providing the inwardly bent reinforcing structure 30 on the circumferential wall of the plug housing 11, the overall structural rigidity of the plug housing 11 is improved. The reinforcing structure 30 makes the plug housing 11 less prone to permanent deformation during mating with the receiving housing 21, especially in areas of high stress. The plug housing 11, reinforced by the reinforcing structure 30, effectively improves the connector's pull-out force, ensuring the reliability and stability of signal transmission. Simultaneously, this design requires no increase in material thickness or alteration of overall dimensions, without affecting the connector's standard specifications or installation space. This structural optimization is simple and easy to implement, suitable for mass production, effectively extending product lifespan and reducing the risk of damage during frequent mating and unmating. Furthermore, the increased structural strength allows the connector to maintain good mechanical properties even in harsh environments, meeting the needs of various application scenarios.
