Description

Technical Field

[0001] The embodiments of the present application relate to the field of connector technology, and in particular to a coaxial connector and a mobile device. Background Art

[0002] RF coaxial connectors are generally considered to be components that are attached to cables or installed on instruments. As components that electrically connect or separate 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 usually consist of two parts: a plug and a receptacle. They use a metal shell and an inner conductor structure to achieve lossless signal transmission through physical contact. In actual application environments, especially mobile devices, aerospace equipment, industrial automation equipment, and automotive electronic systems, equipment often faces high-frequency vibration challenges. These vibrations mainly come from factors such as mechanical moving parts, engine operation, road bumps, or external shocks, and the vibration frequency can range from a few hertz to several thousand hertz.

[0003] While implementing the embodiments of this application, the inventors discovered that, under high-frequency vibration conditions, the connection structure of conventional coaxial connectors relies primarily on friction and elastic force to maintain contact. When the external vibration frequency approaches the natural frequency of the connector, resonance occurs, causing the contact force between the plug and the socket to periodically weaken. As the vibration continues, the plug gradually loosens and eventually pops off, causing signal interruption and degraded communication quality. Summary of the Invention

[0027] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0028] See also 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] See also Figure 2 The plug 10 includes a first housing 11, which is provided with a first interlocking structure 101. The receptacle 20 includes a second housing 21, which is provided 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 receptacle 20 and rotated relative to each other. A limiting structure 30 is provided on the second housing 21. The limiting structure 30 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 receptacle 20.

[0030] In this embodiment, the first housing 11 is made of C5210R-EH material, which has excellent 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 housing 21 is made of C5191R-H material, which has 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 ensure that the coaxial connector 100 of this application maintains excellent electrical conductivity while having sufficient mechanical strength to withstand vibration environments.

[0031] In the embodiment of the present application, a soldering pad (not shown) for surface mounting (SMT) is provided on the second housing 21 to facilitate mounting the socket 20 on a printed circuit board.

[0032] The connection process of the coaxial connector in this embodiment 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 so that the first interlocking structure 101 and the second interlocking structure 201 gradually engage; finally, when the plug 10 is rotated to a predetermined position, the limiting structure 30 abuts against the first shell 11 to complete 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 in a high-frequency vibration environment. 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] See also 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, and the first locking arm 111 and the second locking arm 112 are disposed opposite each other. The first locking arm 111 locks with one end of the second interlocking structure 201, and the second locking arm 112 locks with the other end of the second interlocking structure 201. This arrangement improves the stability of the coaxial connector 100 in high-frequency vibration environments, preventing the plug 10 from falling off the receptacle 20 due to vibration.

[0034] Specifically, the first locking arm 111 is bent in sequence along the width direction of the first housing 11 to form a first extension portion 113, a first bent portion 114, and a first engaging portion 115. The first extension portion 113 extends from the first housing 11 and forms the base of the first locking arm 111. The first bent portion 114 connects the first extension portion 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 a corresponding groove or slot in the second interlocking structure 201, providing a reliable mechanical connection.

[0035] Similarly, the second locking arm 112 is bent in sequence along the width of the first housing 11 to form a second extension 121, a second bent portion 122, and a second engaging portion 123. The second extension 121 extends from the other end of the first housing 11, opposite the first extension 113. The second bent portion 122 connects the second extension 121 and the second engaging portion 123, enabling the second engaging portion 123 to form a locking engagement with the other end of the second interlocking structure 201. The second engaging portion 123 has the same design as the first engaging portion 115 and can securely 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 integrated 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 actual application, when the plug 10 is inserted into the socket 20 at a specific angle (about 30°-35°), the first locking arm 111 and the second locking arm 112 are slightly deformed to adapt to the insertion process. Subsequently, the plug 10 is rotated so that the first clamping portion 115 of the first locking arm 111 and the second clamping portion 123 of the second locking arm 112 gradually engage with the corresponding parts of the second interlocking structure 201. When rotated to a predetermined position, the limiting structure 30 abuts against the first shell 11 to prevent excessive rotation. At this time, the first locking arm 111 and the second locking arm 112 form a firm mechanical connection with the second interlocking structure 201. The coaxial connector 100 provided in this embodiment enhances the stability of the coaxial connector 100 in a high-frequency vibration environment 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 achieves a maximum holding force of 11.34N. When the displacement is 0.05mm, the plug 10 remains connected to the socket 20. Combined with the unlocking force, the total holding force can exceed 22N. This holding force is sufficient to withstand most high-frequency vibration environments, effectively preventing disconnection and signal interruption caused by vibration. Furthermore, the integral molding of the first and second locking arms 111, 112, with the first housing 11 simplifies the number of components, improves structural reliability, and reduces the risk of connection failure due to loose components. This design also facilitates mass production and assembly, reducing manufacturing costs.

[0038] The coaxial connector 100 provided in this embodiment successfully solves the problem of the connector being easily detached in a high-frequency vibration environment in the prior art 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, and provides a reliable signal transmission solution for equipment that needs to work stably in a vibration environment.

[0039] See also Figure 4 The second interlocking structure 201 includes a first limiting side wall 211 and a second limiting side wall 212. The first limiting side wall 211 is provided at one end of the second housing 21, and the second limiting side wall 212 is provided at the other end of the second housing 21, and the first limiting side wall 211 and the second limiting side wall 212 are arranged opposite to each other. This symmetrical design ensures the stability of the connector in a vibration environment and prevents the connection from loosening due to unilateral force. In the connected state, one end of the first locking arm 111 is buckled with the first limiting side wall 211, and one end of the second locking arm 112 is buckled with the second limiting side wall 212, forming a two-way locking structure.

[0040] Specifically, the first position-limiting side arm 211 includes a first receiving portion 213 extending from the second housing 21. The first receiving portion 213 is provided with a first recess 214 for accommodating the first locking arm 111. The first recess 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 engages with the first recess 214, forming an interference fit that provides significant retention force, preventing the plug 10 from loosening or falling off under vibration.

[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 recess 223 for accommodating the second locking arm 112. The second recess 223, similar in design to the first recess 214, forms a precise interference fit with the second engaging portion 123 of the second locking arm 112. The recesses and engaging portions on both sides work together to create a secure mechanical connection, significantly improving the connector's stability in vibration environments.

[0042] It's worth noting that the first limiting sidewall 211, the second limiting sidewall 212, and the second housing 21 are integrally molded. This integrated design not only simplifies the manufacturing process and improves production efficiency, but also enhances the overall strength and rigidity of the second housing 21. Made of high-quality C5191R-H material, the second housing 21 and its limiting sidewalls possess excellent mechanical strength and durability, capable of withstanding prolonged plugging and unplugging operations and environmental vibrations.

[0043] In actual use, 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 side wall 211 and the second limiting side wall 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 locking arms on both sides fully engage with the grooves, and the limiting structure 30 abuts against the first housing 11, preventing excessive rotation. The depth and shape of the first groove 214 and the second groove 223 in this embodiment are designed to ensure 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 11.34N. When the displacement is 0.05mm, the plug 10 remains connected to the socket 20. Combined with the unlocking force, the total holding force can exceed 22N.

[0044] The coaxial connector 100 provided in this embodiment successfully addresses the prior art issue of coaxial connector 100 easily falling off in high-frequency vibration environments through the special design of the first limiting sidewall 211 and the second limiting sidewall 212 in the second interlocking structure 201, particularly the groove structure that precisely mates with the first locking arm 111 and the second locking arm 112. This integrated structural design improves manufacturing efficiency and product reliability, providing an ideal connection solution for devices that require stable operation in vibration environments.

[0045] See also Figure 5 and Figure 6 The limiting structure 30 includes a first stopper 31 and a second stopper 32 disposed on the first limiting sidewall 211. The first and second stops 31, 32 are distributed along the circumference of the first limiting sidewall 211, forming a specific spacing therebetween. The first and second stops 31, 32 together form a first arcuate limiting channel 33. This channel is designed to be arcuate, and its curvature matches the motion trajectory of the first locking arm 111 when the plug 10 rotates. The first arcuate limiting channel 33 can guide the first locking arm 111 to rotate along a predetermined trajectory and ultimately locate it in the locked position, ensuring a smooth connection process and accurate locking.

[0046] To further enhance the stability of the connector, this embodiment also provides corresponding third and fourth stops 34, 35 on the second limiting sidewall 212. The design of the third and fourth stops 34, 35 is identical to that of the first and second stops 31, 32, but they are symmetrically arranged on the second limiting sidewall 212. A second arcuate limiting channel 36 is formed between the third and fourth stops 34, 35, guiding the second locking arm 112 to rotate along a predetermined trajectory and position itself in the locked position. These two arcuate limiting channels work together to ensure that the plug 10 remains balanced during rotation, preventing unstable connections caused by uneven force on one side.

[0047] In this embodiment of the present application, the height of the first and second stops 31, 32 is designed to be slightly higher than the surface of the first limiting side wall 211. This ensures that they can effectively contact and guide the movement of the first locking arm 111. Similarly, the height of the third and fourth stops 34, 35 is also slightly higher than the surface of the second limiting side wall 212 to ensure effective guidance of the second locking arm 112. The surfaces of the stops are finely processed to ensure a smooth and 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 shaking. The angle range of the two arc-shaped limiting channels is designed to be approximately 30°-35°, matching the rotational locking angle of the plug 10 and ensuring that the plug 10 can accurately rotate 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 locked position. In the locked position, the end of the first locking arm 111 is restrained by the first and second stops 31 and 32, and the end of the second locking arm 112 is restrained by the third and fourth stops 34 and 35, preventing the plug 10 from rotating further or in the opposite direction, thus forming a secure locked state.

[0049] Furthermore, the front ends of the first and third stops 31, 34 are each designed with chamfered corners 40, allowing the first locking arm 111 and the second locking arm 112 to initially enter the first and second arc-shaped limiting channels 32, 36, respectively, more smoothly, reducing operational resistance. The rear ends of the second and fourth stops 32, 35 are also designed with corresponding chamfers, facilitating smooth exit of the locking arms when unlocking is required. This detailed design not only enhances operational convenience but also extends the life of the connector.

[0050] Through the above configuration, the coaxial connector 100 provided in this embodiment not only has anti-vibration performance, but also provides positioning and locking functions, making operation more convenient and reliable. The bilaterally symmetrical limit structure design ensures a stable and balanced connection, providing an ideal signal transmission solution for devices that require stable operation in vibrating environments.

[0051] The retaining structure 30 in this embodiment is constructed of materials with different hardness than the first and second housings 11 and 21, ensuring that the retaining structure 30 possesses the appropriate hardness and toughness to withstand repeated insertion and removal operations without damage. By precisely controlling the position and shape of each stopper, the coaxial connector in this embodiment maintains a stable connection in high-frequency vibration environments, effectively preventing vibration-induced loosening and signal interruption.

[0052] See also Figure 7In addition to the first and second housings 11 and 21 and their corresponding interlocking structures, the coaxial connector 100 of this embodiment also includes a complete coaxial transmission line system. Specifically, the plug 10 includes a center conductor 12, which is made of brass and gold-plated to enhance conductivity and oxidation resistance. One end of the center conductor 12 is a pin-shaped structure, and the other end is a soldering terminal for connection to the inner conductor of a coaxial cable.

[0053] Plug 10 also includes an insulator 13 surrounding center conductor 12. This insulator 13 is made of polytetrafluoroethylene (PTFE), a material with excellent insulation properties and low dielectric loss. An outer conductor 14 is positioned around insulator 13 and electrically connected to first housing 11, forming a complete shielding structure.

[0054] Please refer back Figure 4 Inside the receptacle 20, a contact 22 mates with the plug's center conductor 12. Made of a resilient beryllium-copper alloy, this contact 22 is also gold-plated. The design of the contact 22 ensures a reliable electrical connection with the center conductor 12, maintaining stable contact even under vibration. The contact 22 is connected to the receptacle's solder pad via a metal bracket, facilitating surface mounting on a printed circuit board.

[0055] Please refer back Figure 1 The coaxial connector 100 of 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 jacket (not shown). To connect, the outer jacket and outer conductor shielding layer of the coaxial cable must be stripped to an appropriate length to expose the inner conductor and dielectric insulation layer.

[0056] The rear of the plug 10 features a cable-securing structure (not shown), consisting of a cable clamp and a strain relief. The clamp secures the outer sheath of the coaxial cable through an interference fit or snap-fit mechanism, while the strain relief disperses and reduces stress concentration during cable bending, preventing breakage from prolonged use. The inner conductor is connected to the center conductor 12 by welding or crimping, while the outer conductor shield is connected to the outer conductor 14 by crimping or welding, ensuring the integrity of the signal transmission path and effective shielding.

[0057] The embodiment of the present application provides a coaxial connector 100, including a plug 10, a socket 20 and a limiting structure 30, wherein the plug includes a first shell 11, the first shell 11 is provided with a first interlocking structure 101, the socket includes a second shell 21, the second shell 21 is provided with a second interlocking structure 201, the first interlocking structure 101 and the second interlocking structure 201 are engaged with each other to form a mechanical connection when the plug 10 is inserted into the socket 20 and rotated relative to each other, the limiting structure 30 is provided on the second shell 21, the limiting structure 30 and the first shell 11 abut against each other 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, by providing the first interlocking structure 101 and the second interlocking structure Structure 201 effectively solves the technical defect in the prior art that the plug is easily detached from the socket under high-frequency vibration environment. 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 a holding force for the coaxial connector 100, enabling it to maintain a stable connection under harsh vibration conditions, thereby improving 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, thereby improving the convenience and reliability of the operation of the coaxial connector 100. Through the above-mentioned setting, 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 industries, automotive electronics, mobile devices and other fields.

[0058] This embodiment provides a mobile device, including the coaxial connector 100 described in any of the above 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 of the above embodiment to connect signals between a motherboard and an antenna module, between a radio frequency module and a power amplifier module, or between other modules requiring high-frequency signal transmission.

[0060] Mobile devices often experience various vibrations during use, such as walking, running, or riding in public transportation. These vibrations can also cause internal motor vibrations and speaker low-frequency resonances. These vibrations can cause poor contact in traditional connectors, leading to signal interruption or decreased communication quality. The anti-vibration coaxial connector 100, adopted in this embodiment, maintains a stable connection in these vibration environments through its unique interlocking structural design, 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 via a surface mount (SMT) process, forming a secure mechanical connection. The plug 10 is connected to the antenna module or other RF module via a coaxial cable. During installation, the plug 10 is inserted into the socket 20 at an angle of 30°-35°. The plug 10 is then rotated to engage the first interlocking structure 101 with the second interlocking structure 201 until the retaining structure 30 abuts against the first housing 11, completing the locking process.

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

[0063] The above description is merely an embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
