Description

Technical Field

[0001] This application relates to the technical field of radio frequency connectors, and in particular to a radio frequency connector with a coaxial locking mechanism. Background Technology

[0002] Radio frequency (RF) connectors are components that enable signal transmission in high-frequency electronic systems and are widely used in 5G communications, satellite communications, radar, test and measurement, and other fields. As electronic devices move towards miniaturization and high-density installation, push-in RF connectors such as MCX and SMP are widely used in space-constrained environments due to their advantages of quick insertion / removal and compact size.

[0003] The core structure of existing push-in RF connectors includes a connecting body, an inner conductor, an insulator, and a mating interface. Signal transmission is achieved by axially pushing the inner conductor into contact with the insulator. However, existing connectors of this type lack sufficient reliability. Push-in connections rely solely on the interference fit of elastic claws or friction for initial fixation, resulting in weak vibration resistance. During equipment operation, vibration can easily cause the mating interface to unexpectedly disconnect, leading to signal transmission interruption and failing to meet the high reliability requirements of high-frequency electronic systems. Utility Model Content

[0004] To address the shortcomings of push-in connectors in terms of connection reliability, which are prone to accidental disconnection of the mating interface due to vibration, resulting in signal transmission interruption and failing to meet the high reliability requirements of high-frequency electronic systems, this application provides an RF connector with a coaxial locking mechanism.

[0005] This application provides an RF connector with a coaxial locking mechanism, which adopts the following technical solution: A radio frequency connector with a coaxial locking mechanism, comprising: The main component includes a connecting body. An RF input (output) insulator and a first limiting member are coaxially sleeved within the connecting body. The RF input (output) insulator is located on one side of the RF input (output) interface of the connecting body, and the first limiting member is located on one side of the RF output (input) interface of the connecting body. An inner conductor for conducting signals is coaxially sleeved within the RF input (output) insulator, and the inner conductor extends along the axial direction of the RF input (output) insulator into the first limiting member. An RF output (input) insulator is sleeved between the first limiting member and the inner conductor. A locking assembly includes an adjusting member, an elastic element sleeved outside the adjusting member, and a second limiting member. The adjusting member and the elastic element slide and engage between the connecting body and the first limiting member. The second limiting member is coaxially sleeved between the adjusting member and the first limiting member, and the second limiting member is engaged between the adjusting member and the first limiting member at one end near the outer periphery of the RF output (input) interface. The second limiting member can slide out of the other end of the outer periphery between the adjusting member and the first limiting member.

[0006] By adopting the above technical solution, the main components are arranged coaxially, with the inner conductor, insulators at all levels, and the connecting body assembled coaxially to ensure characteristic impedance matching, reduce signal transmission loss and radio frequency leakage, and provide a stable channel for high-frequency signal transmission. The locking assembly controls the engagement and release of the second limiting component through the extension and retraction of the elastic element and the adjustment component, achieving a secure locking and convenient unlocking of the mating connector. This structure retains the quick insertion and removal of the push-in connector while using a mechanical locking structure to prevent accidental disconnection due to vibration during equipment operation. At the same time, the coaxial arrangement ensures stable electrical performance, guaranteeing ease of operation and connection reliability.

[0007] Optionally, the adjusting component includes an adjusting cylinder, a retaining ring, and a limiting ring. One end of the adjusting cylinder is coaxially connected to the retaining ring, and the other end is coaxially connected to the limiting ring for engaging with the first limiting component. The elastic element is sleeved on the outside of the adjusting cylinder.

[0008] By adopting the above technical solution, the adjusting cylinder provides installation and movement space for the second limiting component, the retaining ring serves as a limit for the elastic element and also provides a force support point for the elastic element, ensuring stable force transmission when the elastic element is compressed and reset; the limiting ring engages with the first limiting component to limit the sliding stroke of the adjusting component and prevent damage to the component due to improper operation.

[0009] Optionally, a first mounting step is provided on one side of the radio frequency output (input) interface of the connecting body, and a boss for engaging with the limiting ring is provided on the outside of the first limiting member. The connecting body, the first mounting step, and the boss form a sliding cavity for sliding of the adjusting member and the elastic element.

[0010] By adopting the above technical solution, the first mounting step and the boss cooperate to form a sliding cavity, which provides movement space for the adjusting component and the elastic element, restricts their lateral displacement, and ensures that the adjusting component slides along the axis of the connecting body. The size of the sliding cavity is adapted to the adjusting component and the elastic element, which not only ensures the flexible movement of the components, but also avoids shaking caused by excessive gaps, improves the stability of the locking assembly, and thus ensures the reliability of the connection.

[0011] Optionally, the adjusting member is provided with a snap-fit ​​section, a sliding section, and an unlocking section. The sliding section has the snap-fit ​​section at one end and the unlocking section at the other end. The first limiting member has a snap-fit ​​groove. When the elastic element is in a non-compressed state, the snap-fit ​​section and the snap-fit ​​groove are engaged and locked between the adjusting member and the first limiting member by the second limiting member. When the elastic element is in a compressed state, the sliding section and the unlocking section are engaged with the snap-fit ​​groove by the second limiting member and the second limiting member releases the snap-fit ​​and slides out of the snap-fit ​​section between the adjusting member and the first limiting member.

[0012] By employing the above technical solution, and utilizing the different sections within the adjusting component in conjunction with the state switching of the elastic element, the automatic engagement and unlocking of the second limiting component is achieved. When the elastic element is in the uncompressed state, the engaging section engages with the engaging slot, firmly fixing the second limiting component and ensuring the reliability and stability of the RF connector mating connection. When the elastic element is in the compressed state, the sliding section and unlocking section engage with the engaging slot, eliminating the constraint on the second limiting component and allowing it to slide out smoothly for convenient unlocking. This design, through the corresponding cooperation of the mechanical structure, achieves reliable switching of the locking state and also has a foolproof effect, preventing connection failures caused by misoperation.

[0013] Optionally, the connecting body is provided with a second mounting step for mounting the RF input (output) terminal insulator and a positioning groove for engaging and fixing the first limiting member, and the outer periphery of the first limiting member is provided with a positioning ring that engages with the positioning groove.

[0014] By adopting the above technical solution, the second mounting step provides corresponding mounting positioning for the RF input (output) terminal insulator, ensuring its coaxiality with the connecting body and inner conductor, and guaranteeing insulation performance and signal transmission stability; the positioning groove and positioning ring engage to achieve stable fixation of the first limiting component within the connecting body, preventing displacement in the vibration environment, thereby ensuring the fitting accuracy of the locking assembly and the main body assembly, and improving the structural stability and service life of the entire connector.

[0015] Optionally, a limiting insulator is provided between the radio frequency input (output) terminal insulator and the first limiting member, and along the axial direction of the connecting body.

[0016] By adopting the above technical solution, the limiting insulator further enhances the insulation and isolation effect of the main component, avoids electrical interference between the inner conductor and other metal parts, and at the same time plays an axial limiting role, restricts the relative displacement between the RF input (output) terminal insulator and the first limiting member, ensures the stability of the assembly position of each component, reduces impedance mismatch and signal leakage caused by component offset, and improves the electrical performance reliability of the connector.

[0017] Optionally, the characteristic impedance of the RF connector is matched to be 50 (75) Ω.

[0018] By adopting the above technical solution, the RF connector can be adapted to MCX connectors and can also be matched with a characteristic impedance of 50 (75) Ω. It is not limited to a single MCX connector. Its wide impedance adaptability enhances the versatility of the product and can meet the application needs of different fields such as 5G communication, satellite communication, and radar.

[0019] Optionally, the locking assembly is made of metal.

[0020] By adopting the above technical solution, the metal material has high strength, high wear resistance and good fatigue resistance, and can withstand long-term vibration and impact and repeated insertion and removal operations, thus extending the service life of the locking assembly.

[0021] In summary, this application includes at least one of the following beneficial technical effects: By using a coaxial design and locking structure in conjunction, while retaining the quick insertion and removal of push-in connectors, a secure locking mechanism made of metal is used to achieve a stable lock, effectively resisting vibration interference and preventing accidental disconnection. This solves the core problem of insufficient reliability of traditional push-in connectors, while ensuring low insertion loss and low leakage electrical performance. The locking assembly achieves convenient switching between locking and unlocking through the precise cooperation of elastic elements and adjusting parts, and has a foolproof mechanism. It is simple and labor-saving to operate. At the same time, each component is precisely positioned and assembled through structures such as steps and slots, resulting in strong structural stability and long service life.

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0028] This application discloses an RF connector with a coaxial locking mechanism, referring to... Figures 1-3The RF connector with coaxial locking includes a main body assembly 1 and a locking assembly 2. The main body assembly 1 includes a connecting body 11. An RF input (output) end insulator 12 and a first limiting member 13 are coaxially sleeved inside the connecting body 11. The RF input (output) end insulator 12 is located on the RF input (output) interface side of the connecting body 11, and the first limiting member 13 is located on the RF output (input) interface side of the connecting body 11. An inner conductor 14 for conducting signals is coaxially sleeved inside the RF input (output) end insulator 12, and the inner conductor 14 extends along the axial direction of the RF input (output) end insulator 12 into the first limiting member 13. An RF output (input) end insulator 15 is sleeved between the first limiting member 13 and the inner conductor 14. The locking assembly 2 includes an adjusting member 21, an elastic element 22 sleeved on the adjusting member 21, and a second limiting member 23. The adjusting member 21 and the elastic element 22 slide and are locked between the connecting body 11 and the first limiting member 13. The second limiting member 23 is coaxially sleeved between the adjusting member 21 and the first limiting member 13, and the second limiting member 23 is locked on the outer periphery of the adjusting member 21 and the first limiting member 13 near the RF output (input) interface. The second limiting member 23 can slide out of the other outer periphery between the adjusting member 21 and the first limiting member 13.

[0029] The main body 11 of the main component 1 in this RF connector provides an installation reference and fixed space for all internal components, ensuring the coaxial assembly accuracy of each component. The RF input (output) end insulator 12 plays an electrical insulation and isolation role, effectively blocking the electrical interference between the inner conductor 14 and the external structure, ensuring the safety of signal transmission. At the same time, by positioning the inner conductor 14, it reduces impedance changes during signal transmission, reduces signal reflection and insertion loss, and improves RF transmission performance.

[0030] The first limiting member 13 cooperates with the connecting body 11 to form the installation space of the latch assembly 2, providing end positioning for the RF output (input) end insulator 15 and inner conductor 14, limiting the axial displacement of each component, ensuring the stable assembly position of the inner conductor 14, insulator and other components, avoiding loosening of components due to vibration, ensuring the stability of impedance matching, and at the same time, the first limiting member 13 provides a reliable mating reference for the latch assembly 2, ensuring that the latching and unlocking actions are controllable.

[0031] The inner conductor 14 serves as the channel for radio frequency (RF) signal transmission, directly receiving and conducting high-frequency signals. Its coaxial design ensures the straightness and stability of the signal transmission path, reducing attenuation and interference during transmission, guaranteeing efficient high-frequency signal transmission, and meeting the stringent signal transmission quality requirements of fields such as 5G and satellite communications. The RF output (input) insulator 15 continues the insulation isolation function, preventing signal leakage or short circuits caused by partial insulation failure. It also enhances the structural stability of the inner conductor 14, reduces the impact of vibration on signal transmission, and improves the electrical reliability of the connector.

[0032] In the locking assembly 2, the adjusting component 21 serves as the mounting carrier for the elastic element 22 and the control component for the second limiting component 23. By sliding itself, it drives the second limiting component 23 to switch between engaged and disengaged states. This provides reliable locking control for the connector without affecting the ease of push-in insertion and removal, preventing accidental unlocking. Simultaneously, the structure is adapted to the push-in operation logic, ensuring smooth operation. The elastic element 22 provides elastic driving force to the adjusting component 21. Through its own compression and reset, it drives the adjusting component 21 to slide, thereby controlling the state switching of the second limiting component 23. This ensures the locking mechanism remains locked when there is no external force, improving vibration resistance. It also provides a buffer during unlocking operations, preventing damage to components due to excessive force.

[0033] The second limiting member 23 locks the mating connector by engaging between the adjusting member 21 and the first limiting member 13, solving the problem of traditional push-in connectors relying on friction for fixation and having weak vibration resistance, thus avoiding connection failure caused by vibration during equipment operation; in the unlocked state, the second limiting member 23 can slide out smoothly, ensuring quick insertion and removal of the connector for replacement or repair.

[0034] This RF connector with a coaxial locking mechanism ensures efficient and stable transmission of high-frequency signals through the coaxial arrangement of the main body component 1. Simultaneously, through the synergistic action of the locking component 2, it provides reliable locking and limiting for mating connections while retaining the quick insertion and removal capabilities of the push-in connector. Specifically, the locking component 2 replaces traditional friction-based fixing with a mechanical locking structure, effectively resisting vibration and external interference, preventing accidental disconnection of the mating connector, effectively protecting the mating stability of the push-in RF connector, significantly improving its vibration resistance, reducing failed insertions and removals, effectively extending its service life, and ensuring continuous operation of the equipment under complex working conditions. The automatic reset mechanism driven by the elastic element 22 forms a foolproof mechanism, preventing unlocking due to accidental operation and improving safety.

[0035] refer to Figure 3 , Figure 4 and Figure 5The adjusting component 21 includes an adjusting cylinder 211, a retaining ring 212, and a limiting ring 213. One end of the adjusting cylinder 211 is coaxially connected to the retaining ring 212, and the other end is coaxially connected to the limiting ring 213 for engaging with the first limiting component 13. The elastic element 22 is sleeved on the outside of the adjusting cylinder 211. The adjusting cylinder 211 provides a mounting support surface for the elastic element 22, making the force transmission smoother when the elastic element 22 is compressed and reset. Its interior forms a space for accommodating and moving the second limiting component 23, ensuring the stability of the movement trajectory of the second limiting component 23.

[0036] The retaining ring 212 is coaxially connected to the outside of one end of the adjusting cylinder 211, serving as an axial limiting component for the elastic element 22. It restricts the installation position and compression stroke of the elastic element 22, ensuring that the elastic element 22 always operates within a preset stroke. The retaining ring 212 also acts as a mechanical barrier, preventing the adjusting component 21 from excessively displacing and detaching from the assembly range during sliding, thus improving the overall structural reliability. The limiting ring 213 engages with the boss 132 of the first limiting component 13, forming an end-limiting mechanism for the sliding stroke of the adjusting component 21. This controls the movement stroke of the adjusting component 21, preventing it from colliding hard with other components due to excessive operating force, and protecting the components from damage.

[0037] A first mounting step 111 is provided inside the RF output (input) interface side of the connecting body 11, and a boss 132 for engaging with the limiting ring 213 is provided outside the first limiting member 13. The connecting body 11, the first mounting step 111, and the boss 132 form a sliding cavity for sliding the adjusting member 21 and the elastic element 22. The first mounting step 111 is one end boundary of the sliding cavity, providing an axial support surface for the elastic element 22, ensuring that the elastic element 22 is subjected to uniform force after installation, and ensuring smooth compression and reset actions; at the same time, it can position the initial position of the adjusting member 21, providing a reference for the locking state of the locking assembly 2, ensuring the consistency and reliability of the initial state of the locking.

[0038] The boss 132 engages with the limiting ring 213 of the adjusting member 21, forming the other boundary of the sliding cavity. This controls the maximum sliding stroke of the adjusting member 21, preventing excessive displacement of the adjusting member 21 and potential collision damage. The boss 132 also provides a sliding guide for the adjusting member 21, enhancing the fitting accuracy between the adjusting member 21 and the first limiting member 13. Through the support of the connecting body 11, the boundary definition of the first mounting step 111 and the boss 132, and the guiding fit of the first limiting member 13, a well-structured sliding cavity is formed, providing movement space for the adjusting member 21 and the elastic element 22, regulating their movement trajectory and range, ensuring that all components of the locking assembly 2 work together, and achieving stable switching between locking and unlocking states.

[0039] The adjusting member 21 is provided with a snap-fit ​​section 214, a sliding section 215, and an unlocking section 216. One end of the sliding section 215 is provided with the snap-fit ​​section 214, and the other end is provided with the unlocking section 216. The first limiting member 13 is provided with a snap-fit ​​groove 131. When the elastic element 22 is in a non-compressed state, the snap-fit ​​section 214 and the snap-fit ​​groove 131 are engaged and locked between the adjusting member 21 and the first limiting member 13 by the second limiting member 23. When the elastic element 22 is in a compressed state, the sliding section 215 and the unlocking section 216 are engaged with the snap-fit ​​groove 131 by the second limiting member 23 and the second limiting member 23 releases the snap-fit ​​and slides out of the snap-fit ​​section 214 between the adjusting member 21 and the first limiting member 13.

[0040] The locking section 214 is the section inside the adjusting member 21 that realizes the locking function. Its structure is adapted to the locking groove 131. When the elastic element 22 is not compressed, it forms a stable engagement with the locking groove 131, locking the position of the second limiting member 23, so that the second limiting member 23 can be stably locked between the adjusting member 21 and the first limiting member 13, providing a reliable locking force for the mating connector, solving the problem that traditional push-in connectors rely on friction for fixation and have weak vibration resistance, and ensuring a stable connection state.

[0041] The sliding section 215 connects the engaging section 214 and the unlocking section 216, forming a smooth transition section. Its arc shape serves as a transitional element. During the compression of the elastic element 22, it gradually replaces the engaging section 214 and aligns with the engaging groove 131 as the adjusting member 21 slides, ensuring smooth movement of the second limiting member 23 from the engaged state to the unlocked state without any jamming or sticking, thus improving the smoothness of the latch switching. The unlocking section 216 provides release space for the second limiting member 23. When the elastic element 22 is compressed to a preset stroke, it aligns with the engaging groove 131, releasing the constraint on the second limiting member 23 and allowing it to slide out of the engaging area. This ensures that the mating connectors can be quickly and easily inserted and removed, retaining the operational advantages of push-in connectors. The engaging groove 131 is a reference structure that mates with the internal sections of the adjusting member 21. By corresponding with different sections, it achieves constraint and release control of the second limiting member 23. The elastic element 22 drives the adjusting member 21 to slide by switching between non-compressed and compressed states, thereby causing the locking section 214, sliding section 215, and unlocking section 216 to correspond to the locking groove 131 in sequence, realizing the locking and unlocking cycle of the latch.

[0042] When the elastic element 22 is in an uncompressed state, the adjusting member 21 is constrained to its original position. At this time, the second limiting member 23 is in a locked state, and since the material of the second limiting member 23 is elastic, it cannot be disengaged by non-destructive torque. When the elastic element 22 is in a compressed state, the adjusting member 21 is constrained to its maximum stroke position. At this time, the second limiting member 23 is unrestrained and can be disengaged by conventional torque, thereby removing the push-in RF connector mated to the RF output (input) interface for replacement or repair. The locking assembly 2 effectively ensures the high reliability of the mating connection of the push-in RF connector, avoids poor mating connection or failure caused by vibration during operation, reduces the number of useless insertion and removal operations, and improves the service life of the push-in connector.

[0043] The combination of elastic element 22 and adjustment element 21 can realize a simple and foolproof structure to avoid failure of the push-in RF connector due to incorrect operation and reduce production costs. The second limiting element 23 can effectively reduce production costs while satisfying the locking function and reduce RF leakage during mating connection of the push-in RF connector to a certain extent.

[0044] In addition, the connecting body 11 is provided with a second mounting step 112 for mounting the RF input (output) terminal insulator 12 and a positioning groove 113 for engaging and fixing the first limiting member 13. The outer periphery of the first limiting member 13 is provided with a positioning ring 133 that engages with the positioning groove 113. The second mounting step 112 provides an installation positioning reference for the RF input (output) terminal insulator 12, defines the axial installation position of the insulator, and also provides radial support for the insulator, ensuring the coaxiality of the insulator and the connecting body 11, preventing it from loosening or shifting under vibration, and ensuring stable electrical performance.

[0045] The positioning groove 113 engages with the positioning ring 133 of the first limiting member 13, providing a fixed installation position for the first limiting member 13, limiting its axial and radial displacement, and ensuring the assembly accuracy of the first limiting member 13 and the connecting body 11. Through the second mounting step 112 and the positioning groove 113 on the connecting body 11, positioning and fixing engagements are formed with the RF input (output) terminal insulator 12 and the positioning ring 133 of the first limiting member 13, respectively, forming a stable assembly structure for the main component 1 and ensuring the coaxiality and positional stability of components such as the inner conductor 14 and the insulator.

[0046] A limiting insulator 16 is provided between the RF input (output) terminal insulator 12 and the first limiting member 13, along the axial direction of the connecting body 11. The limiting insulator 16 is used to continue the axial insulation protection, fill the insulation gap between the two, prevent the inner conductor 14 from making electrical contact with the connecting body 11, the first limiting member 13, and other metal components, avoid signal leakage, short circuits, and other problems caused by weak local insulation, ensure the electrical safety of the RF connector, and meet the insulation performance requirements of high-frequency electronic systems. The limiting insulator 16 also limits the relative displacement between the RF input (output) terminal insulator 12 and the first limiting member 13, ensuring the stability of their assembly position, and also helps maintain the coaxiality of the inner conductor 14. Through its own structure, it supports the outer periphery of the inner conductor 14 and prevents the inner conductor 14 from shifting due to vibration or external force.

[0047] RF connectors are not only suitable for MCX connectors and SMP connectors, but also have a characteristic impedance that can be matched to 50 (75) Ω. They are highly adaptable and efficient in transmission, which broadens the application scenarios of connectors and meets the high-frequency signal transmission needs of 5G communication, satellite communication, radar and other fields.

[0048] The locking assembly 2 is made of metal. Metal is structurally robust and resistant to deformation, capable of withstanding the mechanical stress and vibration of repeated insertion and removal, preventing a decrease in transmission accuracy due to long-term use. Its strong dimensional stability ensures that the clearance between components remains within a reasonable range, guaranteeing smooth and unhindered locking switching and improving the reliability of locking control. The elastic element 22 can be a spring. The metal spring utilizes the excellent elastic recovery properties and fatigue resistance of metal to provide a stable elastic driving force for locking state switching, while the structural strength of the metal resists stress damage caused by repeated compression.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
