Description

Technical Field

[0001] This utility model relates to the field of wireless communication technology, and in particular to a radio frequency coaxial connector with extended insertion and removal life. Background Technology

[0002] RF coaxial connectors are widely used in many electronic fields such as wireless communication and satellite communication, responsible for connecting devices and transmitting RF signals. However, traditional products have many drawbacks, such as poor connection stability, simple mechanical plug-in structure, and loosening of the male and female connectors when the device moves. For example, in vehicle communication systems, vehicle bumps can interfere with communication. In terms of electromagnetic interference, with the increase in electronic devices and the increasing complexity of the electromagnetic environment, external interference can easily penetrate the connector and affect the internal signal, and the internal signal can also leak and interfere with surrounding devices. This problem is particularly prominent in data centers. The lifespan of the plug-in connector is also not ideal, the plug-in angle is difficult to control precisely, and the internal structure is prone to damage due to stress concentration. In scenarios such as electronic equipment testing that require frequent plugging and unplugging, failures occur frequently, increasing maintenance costs. In addition, traditional connectors are inconvenient to operate, lack anti-slip and fixing designs, and are prone to connection failure or damage due to improper operation. Therefore, it is urgent to develop new connectors to improve performance and solve the above problems. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] Therefore, the purpose of this utility model is to provide an RF coaxial connector with extended mating life, which can solve the existing problems of connection stability and short mating life.

[0005] To solve the above-mentioned technical problems, this utility model provides an RF coaxial connector with extended insertion and removal life, adopting the following technical solution: It includes a male outer sleeve, a male electromagnetic shielding layer fixedly connected to the outer surface of the male outer sleeve, a magnet compartment fixedly connected to the outer surface of the male electromagnetic shielding layer, a first slider slidably connected inside the magnet compartment, a first fixing sleeve fixedly connected to the outer surface of the first slider, an RF plug fixedly connected to the inner wall of the male outer sleeve, a male wire core pressed into the rear end of the RF plug via a groove, a second fixing sleeve threadedly connected to the inner wall of the front end of the first fixing sleeve, a female electromagnetic shielding layer rotatably connected to the inner wall of the second fixing sleeve, a female outer sleeve fixedly connected to the lower end of the female electromagnetic shielding layer, a male mounting groove provided inside the magnet compartment, a male magnet installed inside the male mounting groove, a female mounting groove provided at the front end of the second fixing sleeve, a female magnet installed inside the female mounting groove, and the male magnet and the female magnet are magnetically connected.

[0006] Optionally, a male threaded plug is threadedly connected to the inner wall of the rear end of the male outer sleeve, and a male anti-slip ring is fixedly connected to the inner wall of the male threaded plug.

[0007] The above technical solution provides the following: the male threaded plug seals the rear end to prevent foreign objects from entering; the male anti-slip ring increases grip friction; it prevents the male sleeve from rotating, thus facilitating connection operations.

[0008] Optionally, the inside of the male anti-slip ring is tightly pressed with a male rubber sheet, and the inside of the male rubber sheet is connected to the male wire core cable.

[0009] The above technical solution uses a male connector sheath to secure and protect the male connector core, ensuring stable signal transmission and extending the lifespan of the core.

[0010] Optionally, a second slider is fixedly connected to the outer surface of the outer sleeve of the female head, and the outer surface of the second slider is rotatably connected to the second fixed sleeve.

[0011] Through the above technical solution, the second slider allows the second fixed sleeve to rotate flexibly relative to the female sleeve, facilitating connection at different angles and enhancing the flexibility of use.

[0012] Optionally, an RF socket is fixedly connected to the inner wall of the outer sleeve of the female connector, and the interior of the RF socket is slidably connected to the RF plug.

[0013] The above technical solution involves a sliding connection between the RF socket and the plug, creating a key signal transmission path and ensuring stable and efficient signal transmission.

[0014] Optionally, a female head threaded plug is threadedly connected to the inner wall of the rear end of the outer sleeve of the female head, and a female head anti-slip ring is fixedly connected to the inner wall of the female head threaded plug.

[0015] The above technical solution involves: a threaded plug at the rear end of the female head, an anti-slip ring on the female head to increase gripping friction, preventing the female head sleeve from rotating, and facilitating a reliable connection.

[0016] Optionally, the inner wall of the female anti-slip ring is press-fitted with a female rubber sheet, and the inner wall of the female rubber sheet is connected with a female wire core.

[0017] The above technical solution secures and protects the female connector core with rubber insulation, ensuring signal transmission and reducing core failures.

[0018] Optionally, the number of magnet compartments is two and they are symmetrically distributed. A limiting block is fixedly connected between the magnet compartments, and the rear end of the limiting block contacts the first slider.

[0019] The above technical solution achieves a more balanced magnetic connection through two symmetrical magnet chambers, and the limiting block restricts the sliding of the slider, ensuring the stability of the connector structure.

[0020] In summary, this utility model has at least one of the following beneficial effects:

[0021] 1. Significantly extended lifespan: The unique slider and sleeve connection structure design gives the male and female connectors excellent relative rotational flexibility during insertion and removal. In actual insertion and removal operations, due to various factors, such as differences in operator technique or limitations of equipment installation location, it is often difficult to achieve completely accurate insertion and removal angles. However, this connector's structural design can automatically adjust the insertion and removal angle, effectively avoiding excessive stress concentration on the internal structure of the connector due to angle deviation. For example, in industrial automation equipment with frequent insertion and removal, this design can significantly reduce the risk of damage to the connector during insertion and removal.

[0022] 2. The magnetic connection between the male and female magnets provides strong attraction and precise positioning for the initial connection, greatly reducing the difficulty of manual alignment and ensuring the efficiency of the connection process. This precise positioning enables quick and accurate connection, avoiding signal transmission instability caused by connection deviation. At the same time, the threaded connection between the first and second fixing sleeves further strengthens the connection between the male and female heads, forming a tight and stable connection structure. Even when the equipment is subjected to strong vibration or frequent movement, such as in vehicle communication equipment, it can effectively prevent the connector from loosening, ensuring the continuity and stability of signal transmission, significantly reducing the occurrence of signal interruption or interference, thereby improving the reliability of the entire communication system.

[0030] Reference Figure 1-4 This utility model provides an extended insertion and removal life radio frequency coaxial connector, which includes a male outer sleeve 1, a male electromagnetic shielding layer 5 fixedly connected to the outer surface of the male outer sleeve 1, a magnet compartment 17 fixedly connected to the outer surface of the male electromagnetic shielding layer 5, a first slider 4 slidably connected inside the magnet compartment 17, a first fixing sleeve 2 fixedly connected to the outer surface of the first slider 4, and a radio frequency plug 23 fixedly connected to the inner wall of the male outer sleeve 1. A male wire core 9 is crimped to the rear end of the radio frequency plug 23 through a groove 24.

[0031] The inner wall of the front end of the first fixed sleeve 2 is threadedly connected to the second fixed sleeve 3. The inner wall of the second fixed sleeve 3 is rotatably connected to the female electromagnetic shielding layer 10. The lower end of the female electromagnetic shielding layer 10 is fixedly connected to the female outer sleeve 12. The magnet compartment 17 is provided with a male mounting groove 21. A male magnet 19 is installed inside the male mounting groove 21. The front end of the second fixed sleeve 3 is provided with a female mounting groove 20. A female magnet 22 is installed inside the female mounting groove 20. The male magnet 19 and the female magnet 22 are magnetically connected. The inner wall of the rear end of the male outer sleeve 1 is threadedly connected to the male threaded plug 6. A male anti-slip ring 8 is fixedly connected to the inner wall of the male threaded plug 6. A male rubber 7 is tightly pressed into the inside of the male anti-slip ring 8. The inside of the male rubber 7 is connected to the male wire core 9 cable.

[0032] A second slider 11 is fixedly connected to the outer surface of the female head outer sleeve 12. The outer surface of the second slider 11 is rotatably connected to the second fixed sleeve 3. An RF socket 25 is fixedly connected to the inner wall of the female head outer sleeve 12. The interior of the RF socket 25 is slidably connected to the RF plug 23. A female head threaded plug 13 is threadedly connected to the inner wall of the rear end of the female head outer sleeve 12. A female head anti-slip ring 14 is fixedly connected to the inner wall of the female head threaded plug 13. A female head rubber 15 is pressed into the inner wall of the female head anti-slip ring 14. A female head wire core 16 is connected to the inner wall of the female head rubber 15. There are two magnet chambers 17, which are symmetrically distributed. A limit block 18 is fixedly connected between the magnet chambers 17. The rear end of the limit block 18 is in contact with the first slider 4.

[0033] Working principle: When connecting this RF coaxial connector, the magnetic connection between the male magnet 19 and the female magnet 22 plays a crucial role. Since the male magnet 19 is placed in the male mounting slot 21 and the female magnet 22 is placed in the female mounting slot 20, the magnetic force between them will cause the male and female connectors to tend to attract each other. This not only helps with initial positioning, facilitating accurate alignment of the male and female connectors by the operator, but also provides a certain pre-tightening force during the connection process, ensuring a tight connection. After the male and female connectors are initially close and aligned, the operator pushes the first fixing sleeve 2 forward. At this time, the first fixing sleeve 2... Through its fixed connection with the first slider 4, the male and female heads move smoothly in cooperation with the first slider 4 within the magnet compartment 17. Simultaneously, because the second fixed sleeve 3 is threadedly connected to the inner wall of the front end of the first fixed sleeve 2, when the operator rotates the second fixed sleeve 3, the outer surface of the second slider 11 is rotatably connected to the second fixed sleeve 3, and the second slider 11 is fixed to the outer surface of the female head outer sleeve 12. This allows the second fixed sleeve 3 to rotate around its axis outside the female head outer sleeve 12. As rotation continues, the second fixed sleeve 3 gradually becomes tightly threadedly connected to the first fixed sleeve 2, further reinforcing the connection between the male and female heads.

[0034] To effectively reduce electromagnetic interference, the connector is equipped with comprehensive electromagnetic shielding measures in its structural design. The male electromagnetic shielding layer 5 is fixedly connected to the outer surface of the male outer sleeve 1 and is located at the bottom of the magnet compartment 17. When the male and female connectors are connected, the male electromagnetic shielding layer 5 and the female electromagnetic shielding layer 10 cooperate with each other to form a relatively closed electromagnetic shielding space.

[0035] The female electromagnetic shielding layer 10 is fixed to the bottom of the second fixed sleeve 3. In the connected state, the male electromagnetic shielding layer 5 and the female electromagnetic shielding layer 10 work together to effectively block external electromagnetic interference from entering the connector and prevent it from affecting the transmission of radio frequency signals. At the same time, it can also prevent the radio frequency signals transmitted inside the connector from leaking outward, ensuring the stability and integrity of signal transmission and improving the reliability of the connector in complex electromagnetic environments.

[0036] The first slider 4 is slidably connected to the inside of the magnet compartment 17, and the outer surface of the first slider 4 is fixedly connected to the first fixing sleeve 2. The outer surface of the second slider 11 is rotatably connected to the second fixing sleeve 3, and the second fixing sleeve 3 is threadedly connected to the inner wall of the front end of the first fixing sleeve 2. During the insertion and removal process, this structural design gives the male and female connectors a certain degree of relative rotational flexibility. When the operator performs the insertion and removal operation, even if there is a slight deviation in the insertion and removal angle, the male and female connectors can adjust the angle through this relative rotation, avoiding excessive stress concentration in the internal structure of the connector due to improper angle, effectively reducing the risk of damage to the connector during the insertion and removal process, thereby significantly extending the insertion and removal life of the connector.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
