Description

Technical Field

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

[0002] Radio frequency (RF) coaxial connectors are generally considered components mounted on cables or instruments, serving as electrical connections or disconnectors for transmission lines. Their core function is to ensure high-quality, low-loss transmission of RF signals between different circuit boards or modules. Traditional RF coaxial connectors typically consist of a plug and a receptacle, employing a metal housing and inner conductor structure to achieve lossless signal transmission through physical contact. In practical applications, especially in mobile devices, aerospace equipment, industrial automation equipment, and automotive electronic systems, equipment frequently faces the challenge of high-frequency vibrations. These vibrations mainly originate from factors such as moving mechanical parts, engine operation, road bumps, or external impacts, with vibration frequencies ranging from a few hertz to several kilohertz.

[0003] In implementing the embodiments of this application, the inventors discovered that: currently, under high-frequency vibration conditions, the connection structure of traditional coaxial connectors mainly relies on friction and elastic force to maintain contact. When the external vibration frequency is close to the natural frequency of the connector, resonance occurs, causing the contact force between the plug and the socket to weaken periodically. As the vibration continues, the plug gradually loosens and eventually completely pops off, causing signal interruption and a decrease in communication quality. Utility Model Content

[0004] The main technical problem solved by the embodiments of this application is to provide a coaxial connector that can effectively solve the technical defect that the plug is easy to fall off the socket under high-frequency vibration environment in the prior art. The meshing mechanical connection formed by the first interlocking structure and the second interlocking structure during the rotation of the plug provides a holding force for the coaxial connector, enabling it to maintain a stable connection under harsh vibration conditions and improve the reliability of signal transmission.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application embodiment is: providing a coaxial connector, including a plug, a socket, and a limiting structure. The plug includes a first housing with a first interlocking structure. The socket includes a second housing with a second interlocking structure. The first and second interlocking structures engage with each other to form a mechanical connection when the plug is inserted into the socket and rotates relative to it. The limiting structure is disposed on the second housing and abuts against the first housing when the plug rotates to a predetermined position. The limiting structure is used to limit the rotation range of the plug relative to the socket.

[0006] Optionally, the first interlocking structure includes a first locking arm and a second locking arm. The first locking arm is disposed at one end of the first housing, and the second locking arm is disposed at the other end of the first housing. The first locking arm and the second locking arm are disposed opposite to each other. The first locking arm is locked to one end of the second interlocking structure, and the second locking arm is locked to the other end of the second interlocking structure.

[0007] Optionally, the first locking arm is bent sequentially along the width direction of the first housing to form a first extension, a first bending portion, and a first locking portion, wherein the first locking portion and one end of the second interlocking structure are locked together.

[0008] Optionally, the second locking arm is bent sequentially along the width direction of the first housing to form a second extension, a second bend, and a second latching portion, wherein the second latching portion and the other end of the second interlocking structure are locked together.

[0009] Optionally, the first locking arm, the second locking arm, and the first housing are integrally formed.

[0010] Optionally, the second interlocking structure includes a first limiting sidewall and a second limiting sidewall. The first limiting sidewall is disposed at one end of the second housing, and the second limiting sidewall is disposed at the other end of the second housing. The first limiting sidewall and the second limiting sidewall are disposed opposite to each other. One end of the first locking arm is engaged with the first limiting sidewall, and one end of the second locking arm is engaged with the second limiting sidewall.

[0011] Optionally, the first limiting side arm includes a first receiving portion extending from the second housing, the first receiving portion having a first groove for accommodating the first locking arm, the first groove and the first locking arm forming an interference fit when the plug is rotated to a predetermined position.

[0012] Optionally, the first limiting sidewall, the second limiting sidewall, and the second outer shell are integrally formed.

[0013] Optionally, the limiting structure includes a first stop and a second stop disposed on the first limiting sidewall, the first stop and the second stop forming a first arc-shaped limiting channel, the first arc-shaped limiting channel guiding the first locking arm to rotate along a predetermined trajectory and be positioned at the locking position.

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

[0015] This application provides a coaxial connector, including a plug, a socket, and a limiting structure. The plug includes a first housing with a first interlocking structure. The socket includes a second housing with a second interlocking structure. The first and second interlocking structures engage with each other to form a mechanical connection when the plug is inserted into the socket and rotates relative to it. The limiting structure is disposed on the second housing and abuts against the first housing when the plug rotates to a predetermined position. The limiting structure limits the rotation range of the plug relative to the socket. By providing the first and second interlocking structures, the high-frequency... To address the technical drawback of plugs easily detaching from sockets under vibration, the first and second interlocking structures form a meshing mechanical connection during plug rotation, providing the connector with retaining force. This ensures a stable connection under harsh vibration conditions, improving signal transmission reliability. The limiting structure design allows the plug to be precisely positioned and locked when rotated to a predetermined position, preventing excessive rotation or backspinning. This enhances the ease of operation and reliability of the coaxial connector. Furthermore, these features maintain the connection within a certain displacement range, preventing signal interruption due to momentary vibration. This provides a more stable signal transmission channel for communication systems, meeting the application needs of industries such as industrial, automotive electronics, and mobile devices.

[0027] 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.

[0028] Please see Figure 1 and Figure 2The coaxial connector 100 provided in this embodiment includes a plug 10, a socket 20, and a limiting structure 30.

[0029] Please see Figure 2 The plug 10 includes a first housing 11, which has a first interlocking structure 101. The socket 20 includes a second housing 21, which has a second interlocking structure 201. The first interlocking structure 101 and the second interlocking structure 201 engage with each other to form a mechanical connection when the plug 10 is inserted into the socket 20 and rotates relative to it. A limiting structure 30 is disposed on the second housing 21 and abuts against the first housing 11 when the plug 10 rotates to a predetermined position. The limiting structure 30 is used to limit the rotation range of the plug 10 relative to the socket 20.

[0030] In this embodiment, the first outer shell 11 is made of C5210R-EH material, which has good mechanical strength and electrical conductivity, with a Young's modulus of 112,000 MPa, a Poisson's ratio of 0.32, and a yield strength of 681 MPa. The second outer shell 21 is made of C5191R-H material, with a Young's modulus of 110,000 MPa, a Poisson's ratio of 0.32, and a yield strength of 580 MPa. These material properties enable the coaxial connector 100 in this application to maintain good electrical conductivity while possessing sufficient mechanical strength to withstand vibration environments.

[0031] In this embodiment, the second housing 21 is provided with pads (not shown) for surface mount technology (SMT) to facilitate mounting the socket 20 on a printed circuit board.

[0032] In this embodiment, the connection process of the coaxial connector is as follows: First, the plug 10 is inserted into the socket 20 at a specific angle of 30° to 35°; then, the plug 10 is rotated to gradually engage the first interlocking structure 101 and the second interlocking structure 201; finally, when the plug 10 is rotated to a predetermined position, the limiting structure 30 abuts against the first housing 11, completing the locking. In the locked state, the mechanical connection formed by the first interlocking structure 101 and the second interlocking structure 201 provides additional holding force, enabling the connector to maintain a stable connection under high-frequency vibration environments. Through finite element analysis, the maximum holding force of the coaxial connector 100 provided in this embodiment in the locked state can reach 11.34N. When the displacement is 0.05mm, the plug 10 still remains connected to the socket 20. Combined with the unlocking force, the total holding force can exceed 22N, which is much higher than the holding force of traditional coaxial connectors.

[0033] Please see Figure 3The first interlocking structure 101 includes a first locking arm 111 and a second locking arm 112. The first locking arm 111 is disposed at one end of the first housing 11, and the second locking arm 112 is disposed at the other end of the first housing 11, with the first locking arm 111 and the second locking arm 112 arranged opposite to each other. The first locking arm 111 is locked into one end of the second interlocking structure 201, and the second locking arm 112 is locked into the other end of the second interlocking structure 201. This configuration improves the stability of the coaxial connector 100 under high-frequency vibration environments and prevents the plug 10 from detaching from the socket 20 due to vibration.

[0034] Specifically, the first locking arm 111 is bent sequentially along the width direction of the first housing 11 to form a first extension 113, a first bend 114, and a first engaging portion 115. The first extension 113 extends from the first housing 11, forming the base portion of the first locking arm 111. The first bend 114 connects the first extension 113 and the first engaging portion 115, enabling the first engaging portion 115 to form a locking engagement with one end of the second interlocking structure 201. The first engaging portion 115 is designed to form a tight fit with the corresponding groove or slot of the second interlocking structure 201, providing a reliable mechanical connection.

[0035] Similarly, the second locking arm 112 is bent sequentially along the width direction of the first housing 11 to form a second extension 121, a second bend 122, and a second locking portion 123. The second extension 121 extends from the other end of the first housing 11 and is opposite to the first extension 113. The second bend 122 connects the second extension 121 and the second locking portion 123, enabling the second locking portion 123 to form a locking engagement with the other end of the second interlocking structure 201. The design of the second locking portion 123 is the same as that of the first locking portion 115, enabling a reliable lock with the second interlocking structure 201.

[0036] It should be noted that the first locking arm 111, the second locking arm 112, and the first housing 11 are integrally molded. This integral molding design not only simplifies the manufacturing process and reduces production costs, but also improves the overall strength and reliability of the coaxial connector 100. By using a material with good elasticity, such as C5210R-EH, the first locking arm 111 and the second locking arm 112 can provide appropriate elastic deformation during insertion and removal, ensuring smooth locking and unlocking operations.

[0037] In practical applications, when the plug 10 is inserted into the socket 20 at a specific angle (approximately 30°-35°), the first locking arm 111 and the second locking arm 112 slightly deform to accommodate the insertion process. Subsequently, the plug 10 is rotated, causing the first engaging portion 115 of the first locking arm 111 and the second engaging portion 123 of the second locking arm 112 to gradually engage with corresponding portions of the second interlocking structure 201. When rotated to a predetermined position, the limiting structure 30 abuts against the first housing 11 to prevent excessive rotation. At this point, the first locking arm 111 and the second locking arm 112 form a secure mechanical connection with the second interlocking structure 201. The coaxial connector 100 provided in this embodiment enhances the stability of the coaxial connector 100 under high-frequency vibration environments through the design of the first locking arm 111 and the second locking arm 112 in the first interlocking structure 101. Finite element analysis shows that this design can achieve a maximum holding force of 11.34 N. Even with a displacement of 0.05 mm, the plug 10 remains connected to the socket 20. Combined with the unlocking force, the total holding force exceeds 22 N. This holding force is sufficient to withstand most high-frequency vibration environments, effectively preventing connection disconnection and signal interruption due to vibration. Furthermore, the integral molding structure of the first locking arm 111 and the second locking arm 112 with the first housing 11 simplifies the number of parts, improves structural reliability, and reduces the risk of connection failure due to loose parts. Simultaneously, this design facilitates mass production and assembly, reducing manufacturing costs.

[0038] The coaxial connector 100 provided in this embodiment, through the design of the first interlocking structure 101 and the second interlocking structure 201, specifically through the structural design of the first locking arm 111 and the second locking arm 112, successfully solves the problem of connectors easily falling off in the high-frequency vibration environment in the prior art, and provides a reliable signal transmission solution for equipment that needs to work stably in a vibration environment.

[0039] Please see Figure 4 The second interlocking structure 201 includes a first limiting sidewall 211 and a second limiting sidewall 212. The first limiting sidewall 211 is disposed at one end of the second housing 21, and the second limiting sidewall 212 is disposed at the other end of the second housing 21, with the first limiting sidewall 211 and the second limiting sidewall 212 arranged opposite to each other. This symmetrical design ensures the stability of the connector under vibration and prevents loosening of the connection due to unilateral force. In the connected state, one end of the first locking arm 111 engages with the first limiting sidewall 211, and one end of the second locking arm 112 engages with the second limiting sidewall 212, forming a bidirectional locking structure.

[0040] Specifically, the first limiting arm 211 includes a first receiving portion 213 extending from the second housing 21. The first receiving portion 213 is provided with a first groove 214 for accommodating the first locking arm 111, and the first groove 214 engages with the first engaging portion 115 of the first locking arm 111. When the plug 10 is rotated to a predetermined position, the first engaging portion 115 of the first locking arm 111 inserts into the first groove 214, forming an interference fit, providing a significant retaining force to prevent the plug 10 from loosening or falling off under vibration conditions.

[0041] Correspondingly, the second limiting sidewall 212 also includes a second receiving portion 221 extending from the second housing 21. The second receiving portion 221 is provided with a second groove 223 for accommodating the second locking arm 112. The design of the second groove 223 is the same as that of the first groove 214, enabling a precise interference fit with the second engaging portion 123 of the second locking arm 112. The grooves and engaging portions on both sides work together to form a stable mechanical connection, significantly improving the stability of the connector in vibration environments.

[0042] It is worth noting that the first limiting sidewall 211, the second limiting sidewall 212, and the second outer shell 21 are integrally molded structures. This integral molding design not only simplifies the manufacturing process and improves production efficiency, but also enhances the overall strength and rigidity of the second outer shell 21. The use of high-quality C5191R-H material gives the second outer shell 21 and its limiting sidewalls excellent mechanical strength and durability, enabling them to withstand long-term insertion and removal operations and environmental vibrations.

[0043] In practical applications, when the plug 10 is inserted into the socket 20 at a specific angle, the first locking arm 111 and the second locking arm 112 approach the first limiting sidewall 211 and the second limiting sidewall 212, respectively. Subsequently, the plug 10 is rotated, causing the first locking arm 111 to gradually move into the first groove 214, and the second locking arm 112 to gradually move into the second groove 223. When rotated to the predetermined position, the two locking arms fully engage with the grooves, at which point the limiting structure 30 abuts against the first outer shell 11 to prevent excessive rotation. In this embodiment, the depth and shape of the first groove 214 and the second groove 223 are designed so that the first locking arm 111 and the second locking arm 112 provide sufficient holding force after insertion without causing material fatigue or damage due to excessive interference. Through finite element analysis optimization, the maximum holding force of this structure can reach 11.34 N. When the displacement is 0.05 mm, the plug 10 remains connected to the socket 20. Combined with the unlocking force, the total holding force can exceed 22 N.

[0044] The coaxial connector 100 provided in this embodiment, through the special design of the first limiting sidewall 211 and the second limiting sidewall 212 in the second interlocking structure 201, especially the groove structure that precisely matches the first locking arm 111 and the second locking arm 112, successfully solves the problem of easy detachment of the coaxial connector 100 under high-frequency vibration environment in the prior art. The one-piece molded structural design improves manufacturing efficiency and product reliability, providing an ideal connection solution for equipment that needs to work stably in vibration environment.

[0045] Please see Figure 5 and Figure 6 The limiting structure 30 includes a first stop 31 and a second stop 32 disposed on the first limiting sidewall 211. The first stop 31 and the second stop 32 are distributed circumferentially along the first limiting sidewall 211, forming a specific interval space between them. The first stop 31 and the second stop 32 together form a first arc-shaped limiting channel 33, which is arc-shaped, and its curvature matches the movement trajectory of the first locking arm 111 when the plug 10 rotates. The first arc-shaped limiting channel 33 can guide the first locking arm 111 to rotate along a predetermined trajectory and finally be positioned in the locked position, ensuring the smooth progress of the connection process and the accuracy of locking.

[0046] To further enhance the stability of the connector, this embodiment also provides corresponding third and fourth stops 34 and 35 on the second limiting sidewall 212. The design of the third and fourth stops 34 and 35 is the same as that of the first and second stops 31, but they are symmetrically arranged on the second limiting sidewall 212. A second arc-shaped limiting channel 36 is formed between the third and fourth stops 34 and 35. This channel is used to guide the second locking arm 112 to rotate along a predetermined trajectory and be positioned in the locking position. The arc-shaped limiting channels on both sides work together to ensure that the plug 10 remains balanced during rotation and to prevent connection instability caused by uneven force on one side.

[0047] In this embodiment, the heights of the first stop 31 and the second stop 32 are designed to be slightly higher than the surface of the first limiting sidewall 211. This ensures that they can effectively contact and guide the movement of the first locking arm 111. Similarly, the heights of the third stop 34 and the fourth stop 35 are also slightly higher than the surface of the second limiting sidewall 212 to ensure effective guidance of the second locking arm 112. The surfaces of the stops are finely machined to ensure a smooth, burr-free surface, reducing friction and wear when in contact with the locking arm.

[0048] It should be noted that the widths of the first arc-shaped limiting channel 33 and the second arc-shaped limiting channel 36 are designed to be slightly larger than the widths of the first locking arm 111 and the second locking arm 112, respectively. This ensures that the locking arms can pass smoothly without creating excessive gaps that could cause wobbling. The angle range of the two arc-shaped limiting channels is designed to be approximately 30°-35°, matching the rotation locking angle of the plug 10, ensuring that the plug 10 can be accurately rotated to the predetermined locking position. During the connection process, when the plug 10 is inserted into the socket 20 at a specific angle, the first locking arm 111 enters the first arc-shaped limiting channel 33, and the second locking arm 112 enters the second arc-shaped limiting channel 36. As the plug 10 rotates, the locking arms on both sides are guided by their respective arc-shaped limiting channels until they reach the locking position. In the locking position, the end of the first locking arm 111 is restricted by the first stop 31 and the second stop 32, and the end of the second locking arm 112 is restricted by the third stop 34 and the fourth stop 35, preventing the plug 10 from continuing to rotate or rotating in the opposite direction, thus forming a stable locking state.

[0049] Furthermore, the front ends of the first stop 31 and the third stop 34 are respectively designed with chamfered structures 40, which makes the first locking arm 111 and the second locking arm 112 enter the first arc-shaped limiting channel 32 and the second arc-shaped limiting channel 36 more smoothly, reducing operating resistance. The rear ends of the second stop 32 and the fourth stop 35 are also designed with corresponding chamfers to facilitate the smooth withdrawal of the locking arms when unlocking is required. This detailed design not only improves the ease of operation but also extends the service life of the connector.

[0050] With the above-described configuration, the coaxial connector 100 provided in this embodiment not only has vibration resistance but also offers positioning and locking functions, making operation more convenient and reliable. The symmetrical dual-sided limiting structure design ensures the stability and balance of the connection, providing an ideal signal transmission solution for equipment that needs to operate stably in vibration environments.

[0051] In this embodiment, the limiting structure 30 and the first outer shell 11 and the second outer shell 21 are made of different materials with different hardness, so that the limiting structure 30 has appropriate hardness and toughness, and can withstand repeated insertion and removal operations without being easily damaged. By precisely controlling the position and shape of each stop, the coaxial connector of this embodiment can maintain a stable connection in a high-frequency vibration environment, effectively preventing connection loosening and signal interruption caused by vibration.

[0052] Please see Figure 7In addition to the first housing 11, the second housing 21, and the corresponding interlocking structures described above, the coaxial connector 100 of this embodiment also includes a complete coaxial transmission line system. Specifically, the plug 10 has a center conductor 12 inside, which is made of brass and plated with gold to improve conductivity and oxidation resistance. One end of the center conductor 12 is a needle-like structure, and the other end is a solder end, used to connect with the inner conductor of the coaxial cable.

[0053] The plug 10 also includes an insulator 13 surrounding the central conductor 12. The insulator 13 is made of polytetrafluoroethylene (PTFE) material, which has excellent insulation properties and low dielectric loss characteristics. An outer conductor 14 is provided around the insulator 13. The outer conductor 14 is electrically connected to the first outer shell 11 to form a complete shielding structure.

[0054] Please reconsider. Figure 4 The socket 20 contains a contact 22 that matches the center conductor 12 of the plug. This contact 22 is made of a highly elastic beryllium copper alloy and is also gold-plated. The design of the contact 22 ensures a reliable electrical connection when it contacts the center conductor 12, maintaining stable contact even under vibration conditions. The contact 22 is connected to the socket's pads via a metal bracket, facilitating surface mounting onto a printed circuit board.

[0055] Please reconsider. Figure 1 The coaxial connector 100 in this embodiment is designed to connect a coaxial cable 40 with an impedance of 50Ω. The compatible coaxial cable 40 includes an inner conductor (not shown), a dielectric insulation layer (not shown), an outer conductor shielding layer (not shown), and an outer sheath (not shown). During connection, the outer sheath and outer conductor shielding layer of the coaxial cable need to be stripped to an appropriate length to expose the inner conductor and dielectric insulation layer.

[0056] The rear of the plug 10 is equipped with a cable fixing structure (not shown), which includes a cable clamping part and a strain relief part. The cable clamping part secures the outer sheath of the coaxial cable through an interference fit or a snap-fit ​​structure, while the strain relief part disperses and reduces stress concentration when the cable is bent, preventing cable breakage due to long-term use. The inner conductor is connected to the center conductor 12 by welding or crimping, and the outer conductor shielding layer is connected to the outer conductor 14 by crimping or welding, ensuring the integrity of the signal transmission path and the shielding effect.

[0057] This application provides a coaxial connector 100, including a plug 10, a socket 20, and a limiting structure 30. The plug includes a first housing 11 with a first interlocking structure 101. The socket includes a second housing 21 with a second interlocking structure 201. The first interlocking structure 101 and the second interlocking structure 201 engage with each other to form a mechanical connection when the plug 10 is inserted into the socket 20 and rotates relative to each other. The limiting structure 30 is disposed on the second housing 21 and abuts against the first housing 11 when the plug 10 rotates to a predetermined position. The limiting structure 30 is used to limit the rotation range of the plug 10 relative to the socket 20. The first interlocking structure 101 and the second interlocking structure 201 are used to limit the rotation range of the plug 10 relative to the socket 20. Structure 201 effectively solves the technical defect of the plug easily falling off the socket under high-frequency vibration environment in the prior art. The meshing mechanical connection formed by the first interlocking structure 101 and the second interlocking structure 201 during the rotation of the plug 10 provides the coaxial connector 100 with holding force, enabling it to maintain a stable connection under harsh vibration conditions and improve the reliability of signal transmission. The design of the limiting structure 30 enables the plug 10 to be accurately positioned and locked when rotated to a predetermined position, preventing excessive rotation or back rotation, and improving the convenience and reliability of the operation of the coaxial connector 100. Through the above settings, the connection state can also be maintained within a certain displacement range, avoiding signal interruption caused by instantaneous vibration, providing a more stable signal transmission channel for the communication system, and meeting the application needs of industrial, automotive electronics and mobile devices.

[0058] This embodiment provides a mobile device, including the coaxial connector 100 described in any of the foregoing embodiments.

[0059] The mobile device provided in this embodiment can be a smartphone, tablet computer, portable gaming device, wearable device, or other type of mobile communication terminal. The mobile device integrates the coaxial connector 100 described in the above embodiment for connecting the motherboard to the antenna module, the RF module to the power amplifier module, or other modules requiring high-frequency signal transmission.

[0060] During the use of mobile devices, various situations that cause device vibration are frequently encountered, such as users walking, running, or riding in vehicles, as well as internal factors such as motor vibration and low-frequency resonance of speakers. These vibrations may lead to poor contact in traditional connectors, resulting in signal interruption or degraded communication quality. The vibration-resistant coaxial connector 100 used in this embodiment, through its unique interlocking structure design, can maintain a stable connection under the aforementioned vibration environments, ensuring continuous and stable signal transmission.

[0061] Specifically, the coaxial connector 100 is mounted on the motherboard of the mobile device 3, and the socket 20 is fixed to the printed circuit board using surface mount technology (SMT) to form a robust mechanical connection. The plug 10 is connected to the antenna module or other RF modules via a coaxial cable. During installation, the plug 10 is inserted into the socket 20 at an angle of 30°-35°, and then the plug 10 is rotated to engage the first interlocking structure 101 with the second interlocking structure 201 until the limiting structure 30 abuts against the first housing 11, completing the locking process.

[0062] The mobile device in this embodiment solves the signal instability problem that may occur in traditional mobile devices under vibration environment by adopting a coaxial connector 100 with anti-vibration characteristics.
