Description

Technical Field

[0001] This utility model relates to the field of radio frequency coaxial connector technology, specifically a snap-fit ​​pin structure and its radio frequency coaxial connector. Background Technology

[0002] A radio frequency (RF) coaxial connector is an electromechanical component used to transmit radio frequency (RF) signals. It is typically mounted on cables or equipment as a bridge for electrical connection or disconnection of transmission lines. Based on the principle of coaxial transmission lines, it consists of an inner conductor, an insulating medium, and an outer conductor. The inner conductor is responsible for signal transmission, the outer conductor provides shielding and grounding, and the insulating medium maintains a fixed distance between the inner and outer conductors to ensure the stability of the characteristic impedance. This type of connector has excellent shielding performance, stable impedance characteristics, and low voltage standing wave ratio (VSWR), which can reduce signal loss and distortion. It is widely used in communications, broadcasting, aerospace, military and other fields and is the most common standardized connector type in RF transmission. Existing RF coaxial connectors typically achieve direct snap-fit ​​during installation through structural deformation. While this installation method is simple, it requires prying open during disassembly. Improper handling can easily lead to breakage of the snap-fit ​​structure. Once the snap-fit ​​structure breaks, not only will the connector become unusable, but it may also damage other components of the connector, and even damage the connected equipment or cables. This not only increases maintenance costs but may also affect the normal operation of the equipment. Therefore, to address the above problems, a snap-fit ​​pin structure and its RF coaxial connector are proposed. Utility Model Content

[0014] 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.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-7 This utility model provides a technical solution: A snap-fit ​​pin structure and its radio frequency coaxial connector include a female connector assembly 1, a male connector assembly 2 inserted into the front end of the female connector assembly 1, and a snap-fit ​​assembly 3 installed inside the male connector assembly 2. The female connector assembly 1 includes a female body 11, with planar grooves 12 at both the upper and lower ends. The inner side of the female body 11 has a snap-fit ​​groove 13, an arc-shaped groove 14, and a disassembly groove 15. The male connector assembly 2 includes a male body 21, which is integrally fixedly connected to an operation plate 22. The inner side of the operation plate 22 has a guide groove 23, and a guide block 24 is fixedly connected to the inner side of the guide groove 23. A spring telescopic rod 25 is fixedly connected to the front end of the operation plate 22. The snap-fit ​​assembly 3 includes a horizontal plate 31, with a snap-fit ​​head 32 fixedly connected to one side of the horizontal plate 31. A first stop block 33, a connecting arm 36, and a second stop block 35 are sequentially fixedly connected to the front end of the horizontal plate 31. A limit groove 34 is provided inside the connecting arm 36.

[0017] As a further implementation of this solution, the rear end of the male terminal body 21 is inserted into the inner side of the female terminal body 11, and the front end of the female terminal body 11 is attached to the rear end of the operation board 22. Through the above settings, the stability of the connection is ensured. At the same time, the attachment of the front end of the female terminal body 11 to the rear end of the operation board 22 can effectively reduce the loss during signal transmission and improve the efficiency and quality of signal transmission. As a further implementation of this solution, the slot 13, the arc-shaped groove 14, and the disassembly groove 15 are connected. The slot 13 extends forward based on the arc-shaped groove 14, and the disassembly groove 15 penetrates the front end of the female end body 11. The slot 13 is located in the middle of the planar groove 12. Through the above arrangement, the continuity and stability of the signal during transmission can be ensured. The design of the disassembly groove 15 penetrating the front end of the female end body 11 provides sufficient space for the snap-fit ​​and enhances the overall structural strength of the connector. As a further implementation of this solution, the horizontal plate 31 is fitted with the flat groove 12, and the locking head 32 is locked inside the groove 13. A gap is provided between the front end of the locking head 32 and the rear end of the groove 13. Through the above settings, it can be ensured that the horizontal plate 31 can fit tightly with the flat groove 12 when the deformation is restored, thereby improving the stability of the locking. The gap design between the front end of the locking head 32 and the rear end of the groove 13 provides sufficient space for the deformation of the locking head 32, reduces the damage to the locking head 32 during the locking process, and extends the service life of the connector. As a further implementation of this solution, the guide block 24 is located inside the guide groove 23 and slides inside the limiting groove 34. Through the above setting, it plays a role in guiding the movement of the connecting arm 36, preventing the connecting arm 36 from twisting, and ensuring the effectiveness of the card head 32 opening inside the card slot 13. As a further implementation of this solution, the front end of the piston rod of the spring telescopic rod 25 is fixedly connected to the rear end of the second stop 35, and the spring telescopic rod 25 is embedded in the limiting groove 34. Through the above settings, this design not only improves the installation and disassembly efficiency of the connector, but also enhances the structural stability of the connector and reduces the loosening of the connection due to insufficient spring force. As a further implementation of this solution, the front end of the limiting groove 34 extends to the rear end of the second stop 35, and the rear end of the limiting groove 34 extends to the front end of the first stop 33. The rear end of the first stop 33 is in close contact with the front end of the operation plate 22. Through the above settings, the assembly space occupied is reduced, and the close contact design between the rear end of the first stop 33 and the front end of the operation plate 22 further enhances the stability of the connector signal transmission.

[0018] Workflow: During engagement, align the male end body 21 with the groove inside the female end body 11, and simultaneously align the locking head 32 with the flat groove 12. Move the female end body 11 and male end body 21 closer together. When the locking head 32 contacts the front end of the flat groove 12, due to the slope of the locking head 32, the locking head 32 will move under the reaction force, causing the horizontal plate 31 to deform. During this process, the first stop 33 will remain in close contact with the operating plate 22. When the front end of the locking head 32 contacts the horizontal plate 21... After the front end of the slot 13 is aligned, the clamp 32 engages with the inside of the slot 13 under the action of the deformation recovery of the horizontal plate 31, and the installation is completed. Under the elastic extension of the spring telescopic rod 25, the second stop 35, the connecting arm 36 and the first stop 33 will be pushed forward, so that the first stop 33 is in close contact with the operating plate 22, and the front end of the clamp 32 is in close contact with the front end of the slot 13. In this way, the clamp 32 will not be aligned with the arc groove 14, thereby improving the stability of the RF coaxial connector after installation. During disassembly, use your index and middle fingers to push the second stop 35 forward simultaneously. The second stop 35 drives the connecting arm 36, the first stop 33, the horizontal plate 31, and the locking head 32 to move forward simultaneously. The connecting arm 36 slides through the limiting groove 34 and the guide groove 23. The second stop 35 presses against the spring telescopic rod 25. At this time, the locking head 32 aligns with the arc-shaped groove 14. Then, operate the operating plate 22 to rotate the entire connector male end assembly 2. The connector male end assembly 2 drives the two locking assemblies 3 to rotate simultaneously. When the two locking heads 32 are aligned with the disassembly groove 15, pull the female end body 11 and the male end body 21 to move away from each other, so that the locking head 32 is disengaged from the disassembly groove 15 and the male end body 21 is disengaged from the female end body 11, thus completing the disassembly. Based on the above principles, the snap-fit ​​installation method of the device is not only convenient for installation, but also allows for separation between the male end body 21 and the female end body 11 without having to pry the snap-fit ​​structure during disassembly. This disassembly method is suitable for frequent installation and disassembly, significantly reducing the probability of damage to the RF coaxial connector due to improper operation, reducing maintenance costs, and ensuring normal operation of the equipment.
