Description

Technical Field

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

[0002] Radio frequency (RF) coaxial connectors are generally considered to be components mounted on cables or instruments, serving as electrical connections or disconnections between 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. They achieve lossless signal transmission through physical contact, with the receptacle fixed to the printed circuit board.

[0003] In implementing the embodiments of this application, the inventors discovered that when a pulling force is applied to the cable end of the connector, the outer shell of the socket is prone to yielding deformation due to insufficient strength when subjected to lateral pressure, which in turn causes damage to the printed circuit board.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application embodiment is: to provide a connector, including a plug, a socket, a first locking structure and a second locking structure, wherein the first locking structure is fixed to the plug, the second locking structure is sleeved on the socket, the second locking structure includes a first locking arm, a connecting part and a second locking arm, the connecting part is connected to the first locking arm and the second locking arm respectively, the first locking arm is provided with a first locking part and a first welding surface, the first welding surface is used for welding and fixing to a circuit board, and the first locking part cooperates with the first locking structure to form a locking connection.

[0006] Optionally, the first locking arm, the connecting part, and the second locking arm are integrally formed.

[0009] Optionally, the second limiting plate is further provided with a first welding foot, which is used to weld and fix it to the circuit board.

[0010] Optionally, the second locking arm is provided with a second locking part and a second welding surface. The second welding surface is used for welding and fixing to the circuit board, and the second locking part cooperates with the second locking structure to form a locking connection.

[0011] Optionally, the first locking structure includes a second stop plate, the second locking part includes a third limiting plate, a fourth limiting plate and a second locking base, the second welding surface is disposed on the second locking base, the second locking base is connected to the third limiting plate and the fourth limiting plate respectively, and one end of the third limiting plate and one end of the fourth limiting plate are connected to form a second guide slide, and the second stop plate can slide relative to the second guide slide.

[0013] Optionally, the first stop plate further includes a first abutting arm, the first abutting arm is further provided with a first abutting part, the first guide arm is connected to the first abutting arm, the first abutting arm abuts against the wall of the first locking cavity, and the first abutting part abuts against the side wall of the first limiting plate.

[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 connectors mentioned above.

[0015] This application provides a connector including a plug, a socket, a first locking structure, and a second locking structure. The first locking structure is fixed to the plug, and the second locking structure is sleeved on the socket. The second locking structure includes a first locking arm, a connecting portion, and a second locking arm. The connecting portion is connected to the first locking arm and the second locking arm, respectively. The first locking arm has a first locking portion and a first welding surface. The first welding surface is used for welding and fixing to a circuit board. The first locking portion cooperates with the first locking structure to form a locking connection. When the connector is subjected to a pulling force from the cable end, the second locking structure formed by the first locking arm, the connecting portion, and the second locking arm can effectively disperse and transfer stress, improving the overall deformation resistance of the socket. Furthermore, the connecting portion of the second locking structure avoids local stress concentration. When subjected to lateral pressure, the load is distributed throughout the second locking structure through the connecting portion, making it less likely for the structure to reach the material yield strength, thereby effectively preventing permanent deformation. This structural improvement directly reduces the risk of yield deformation of the socket shell and protects the integrity of the welded connection with the circuit board. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1 and Figure 2This embodiment provides a connector 100, which adopts an integrally formed second locking structure 40 design, effectively solving the technical problem of insufficient strength of the socket 20 in the prior art.

[0022] Connector 100 includes a plug 10, a socket 20, a first locking structure 30, and a second locking structure 40. The plug 10, as the active connecting component of connector 100, is inserted into the socket 20 to achieve an electrical connection. The socket 20, as the passive connecting component of connector 100, is fixedly mounted on a printed circuit board and provides a connection interface for the plug 10. The first locking structure 30 is fixedly mounted on the plug 10 and engages with a locking mechanism at the socket 20 end to ensure a stable connection between the plug 10 and the socket 20. The first locking structure 30 is made of metal and has sufficient strength and durability to withstand multiple insertion and removal operations without deformation. The second locking structure 40 is installed on the socket 20 by a sleeve method. The second locking structure 40 includes a first locking arm 41, a connecting part 42, and a second locking arm 43. The first locking arm 41 and the second locking arm 43 are respectively disposed on both sides of the socket 20 to form a symmetrical locking configuration. The connecting part 42 is located between the first locking arm 41 and the second locking arm 43. The connecting part 42 forms a rigid connection with the first locking arm 41 and the second locking arm 43 respectively, connecting the two originally independent locking arms into a whole structure.

[0023] For details, please refer to Figure 2 The first locking arm 41 is provided with a first locking part 401 and a first welding surface 402. The first locking part 401 is located at the front end of the first locking arm 41, and its structural design matches the first locking structure 30. When the first locking part 401 and the first locking structure 30 are engaged, a reliable locking connection can be formed. The first welding surface 402 is located at the bottom of the first locking arm 41 and has a flat metal surface design. The first welding surface 402 is used to weld and fix it to the printed circuit board, ensuring the mechanical and electrical connection between the connector 100 and the circuit board. In this embodiment, the first locking arm 41, the connecting part 42, and the second locking arm 43 are manufactured as a single piece. The single-piece structure is manufactured into a seamless integral metal part by means of processes such as mold pressing or machining. The single-piece structure eliminates the weak connection points existing in the traditional split structure and improves the overall strength and rigidity of the second locking structure 40.

[0024] When connector 100 is subjected to pulling force from the cable end, the external force is transmitted through plug 10 to the first locking structure 30, and then to the first locking part 401 that cooperates with the first locking structure 30. Since the connecting part 42 connects the first locking arm 41 and the second locking arm 43 into a single structure, the external force acting on the first locking part 401 can be dispersed to the second locking arm 43 through the connecting part 42, avoiding the problem of excessive local stress caused by the force being concentrated on a single locking arm. Furthermore, the integrally molded connecting part 42 has a sufficient cross-sectional area and a reasonable geometry, enabling it to effectively transmit stress without breakage or plastic deformation. The stress transmission effect of the connecting part 42 allows the second locking structure 40 to exhibit excellent overall performance when subjected to external forces, effectively preventing yielding deformation of the socket 20 housing and protecting the integrity of the connection with the printed circuit board.

[0025] Please see Figure 3 and Figure 4 The first locking structure 30 includes a first stop plate 31, and the first locking part 401 includes a first limiting plate 411, a second limiting plate 412, and a first locking base 413. A first welding surface 402 is disposed on the first locking base 413, which serves as the main structure of the first locking part 401 and undertakes the connection function with the printed circuit board. The first locking base 413 is connected to the first limiting plate 411 and the second limiting plate 412 respectively, forming a stable ternary structure combination. One end of the first limiting plate 411 is connected to one end of the second limiting plate 412, and the ends of the first limiting plate 411 and the second limiting plate 412 are connected to form a first guide slide 414. The first guide slide 414 has a preset width and depth dimensions, and the geometric parameters of the first guide slide 414 match the corresponding part of the first stop plate 31. The first stop plate 31 can slide relative to the first guide slide 414, and the sliding process realizes the closing and opening operation of the locking mechanism.

[0026] For further information, please refer to [link / reference]. Figure 4The first stop plate 31 includes a first guide arm 311 as a guiding and positioning component. A first limiting plate 411, a second limiting plate 412, and a first locking base 413 enclose a first locking cavity 415, which provides accommodating space when the first stop plate 31 is fully locked. A first guide slide 414 is provided with a first guide port 416, which serves as the starting position for the first guide arm 311 to enter the first guide slide 414. During the locking process, the first guide arm 311 enters the first guide slide 414 from the first guide port 416 and is guided along a predetermined path in the first guide slide 414 to the first locking cavity 415. The sliding movement of the first guide arm 311 within the first guide slide 414 has good guiding and stability, ensuring a smooth locking process. After the first guide arm 311 reaches the first locking cavity 415, the first stop plate 31 and the first locking part 401 form a fully locked state. The design of the first guide slide 414 ensures that the first stop plate 31 maintains the correct movement trajectory during sliding, avoiding jamming or displacement. The volume and shape of the first locking cavity 415 precisely correspond to the final locking position of the first stop plate 31, achieving a tight fit without any excess gap. The connecting part 42 connects the first locking arm 41 and the second locking arm 43 into a whole, so that the external force acting on the locking mechanism can be effectively dispersed through the connecting part 42, improving the overall deformation resistance and service life of the connector 100.

[0027] It should be noted that the first limiting plate 411 is a connecting end for connecting with the second limiting plate 412, and the second limiting plate 412 is a connecting end for connecting with the first limiting plate 411. Both connecting ends are designed with adjustable size and can be customized according to actual application needs and structural requirements.

[0028] The size adjustment of the connector end is mainly reflected in the changes of parameters in three dimensions: length, width, and thickness, which can adapt to different socket sizes and circuit board layout requirements. When used in compact electronic devices, the connector end length can be set to a minimum configuration of 0.200000 mm, ensuring the miniaturization of the overall size of the connector 100. When used in large communication equipment, the connector end length can be extended to 2.30000 mm, providing stronger structural strength and greater stress dispersion capabilities.

[0029] The dimensional adjustment is achieved using a modular design concept. During manufacturing, precise control of the connection end dimensions is achieved by changing processing molds of different specifications or adjusting CNC machining parameters. The one-piece molding process ensures that connection ends of different sizes maintain the same material density and mechanical properties, avoiding performance differences caused by dimensional variations.

[0030] In this embodiment, the second limiting plate 412 extends to include a first welding foot 417, which serves as an additional welding connection point. The first welding foot 417 is used for welding and fixing to the printed circuit board. It cooperates with the first welding surface 402 to provide double welding fixation protection. The first welding foot 417 enhances the connection strength between the connector 100 and the printed circuit board, effectively dispersing welding stress and improving connection reliability.

[0031] In this embodiment, the second locking structure 40 further includes a first connecting arm 418 and a second connecting arm 438. The first connecting arm 418 is connected to the first locking arm 41 and the first locking part 403, respectively. The second connecting arm 438 is connected to the second locking arm 43 and the second locking part 431, respectively. The positions of the first connecting arm 418 and the second connecting arm 438 can be selected in multiple ways, allowing for flexible configuration according to different application requirements and space constraints. The first connecting arm 418 and the second connecting arm 438 can be located at one end of the first locking arm 41 and the second locking arm 43, forming an arch bridge-type connection structure, suitable for installation environments with ample vertical space. The connecting part can also be located on the side of the first locking arm 41 and the second locking arm 43, forming a beam-type connection structure, suitable for compact application scenarios with limited horizontal space.

[0032] The first connecting arm 418 and the second connecting arm 438 can also be configured with multiple points of connection. Two or more first connecting arms 418 and second connecting arms 438 are arranged between the first locking arm 41 and the second locking arm 43, located in different spatial positions, forming multiple connection supports. The multi-point connection configuration significantly enhances the overall stiffness and load distribution capability of the second locking structure.

[0033] The flexible selection of the positions of the first connecting arm 418 and the second connecting arm 438 provides greater freedom in product design. Designers can choose the optimal configuration of the first connecting arm 418 and the second connecting arm 438 based on the specific circuit board layout, the distribution of surrounding components, and assembly process requirements. This design flexibility improves the adaptability and versatility of connector products, reduces customized development costs, and accelerates the product's market launch.

[0034] For further details, please refer to Figure 4The connector 100 adopts a double-sided symmetrical locking mechanism design. By setting complete locking systems on both sides of the second locking structure 40, a more stable and reliable connection effect is achieved. Specifically, the second locking arm 43 is provided with a second locking part 431 and a second welding surface 432, forming a symmetrical function with the first locking arm 41. The second welding surface 432 is used for welding and fixing to the printed circuit board. The second welding surface 432 and the first welding surface 402 together undertake the fixed connection between the connector 100 and the printed circuit board. The second locking part 431 cooperates with the first locking structure 30 to form a locking connection, realizing double locking protection on both sides of the connector 100.

[0035] The first locking structure 30 includes a second stop plate 32, which uses the same material and manufacturing process as the first stop plate 31 to ensure consistent mechanical properties and service life. The geometry of the second stop plate 32 precisely matches the internal structure of the second locking part 431, ensuring the accuracy and reliability of the locking process. The second locking part 431 includes a third limiting plate 433, a fourth limiting plate 434, and a second locking base 435. The second welding surface 432 is disposed on the second locking base 435, which undertakes the main function of the second locking part 431 and provides a connection interface with the printed circuit board. The second locking base 435 is connected to the third limiting plate 433 and the fourth limiting plate 434 respectively, forming a ternary structure configuration corresponding to the first locking part 401. One end of the third limiting plate 433 is connected to one end of the fourth limiting plate 434, and the ends of the two limiting plates are connected to form a second guide slide 436. The width, depth, and other technical parameters of the second guide slide 436 are consistent with those of the first guide slide 414, ensuring that the locking mechanisms on both sides have the same operating characteristics. The second stop plate 32 can slide relative to the second guide slide 436, and the sliding process realizes the locking and unlocking operation of the second locking part 431.

[0036] Please see Figure 3 and Figure 5 The second stop plate 32 includes a second guide arm 321 as a guiding and positioning component. The third limiting plate 433, the fourth limiting plate 434, and the second locking base 435 enclose and form a second locking cavity 438, which provides a receiving space for the second stop plate 32 in a fully locked state. The second guide slide 436 is provided with a second guide port 437, which serves as the starting position for the second guide arm 321 to enter the second guide slide 436.

[0037] The second guide arm 321 enters the second guide slide 436 from the second guide port 437 and is guided along the predetermined trajectory of the second guide slide 436 to the second locking cavity 438. The sliding process of the second guide arm 321 is consistent with the movement of the first guide arm 311, ensuring that the locking mechanisms on both sides can complete the locking operation synchronously. After the second guide arm 321 reaches the second locking cavity 438, the second stop plate 32 and the second locking part 431 form a stable locking connection.

[0038] In the embodiments of this application, please continue to refer to Figure 4 The first stop plate 31 also includes a first abutting arm 312 as an auxiliary mechanism to enhance positioning accuracy. The first abutting arm 312 is provided with a first abutting portion 314, which provides an additional contact surface for precise positioning. The first guide arm 311 is connected to the first abutting arm 312, forming a composite structure configuration of the first stop plate 31. The first abutting arm 312 abuts against the wall of the first locking cavity 415, providing stable support through surface contact. The first abutting portion 314 abuts against the side wall of the first limiting plate 411, and the contact between the first abutting portion 314 and the side wall of the first limiting plate 411 ensures the precise positioning of the first stop plate 31 in the locked state. The first abutting portion 314 eliminates the slight displacement of the first stop plate 31 within the first locking cavity 415, significantly improving the stability and reliability of the locking connection.

[0039] Accordingly, please refer to Figure 5 The second stop plate 32 further includes a second abutting arm 322, which has a second abutting portion 324. The second abutting portion 324 provides a contact surface corresponding to the first abutting portion 314 for precise positioning. The second guide arm 321 is connected to the second abutting arm 322, forming a composite structure configuration of the second stop plate 32. The second abutting arm 322 abuts against the wall of the second locking cavity 438, providing stable support through surface contact. The second abutting portion 324 abuts against the side wall of the third limiting plate 433, and the contact between the second abutting portion 324 and the side wall of the third limiting plate 433 ensures the precise positioning of the second stop plate 32 in the locked state.

[0040] In this embodiment, the symmetrical design of the dual-sided abutment mechanism achieves high-precision positioning and stability assurance of the locking system. The arrangement of the first abutment part 314 and the second abutment part 324 eliminates the slight displacement of the first stop plate 31 and the second stop plate 32 within their respective locking cavities, significantly improving the stability and reliability of the locking connection. The synchronous action of the two abutment mechanisms ensures that the connector 100 has extremely high positional accuracy and connection strength in the locked state.

[0041] When a pulling force is applied to the cable end, the external force is simultaneously transmitted to the first locking part 401 and the second locking part 431 through the first locking structure 30. The two locking parts, together with the integral structure formed by the connecting part 42, jointly bear the external force. The double-sided abutment system composed of the first abutment arm 312, the second abutment arm 322, and the corresponding abutment parts further enhances the overall rigidity of the locking mechanism, effectively preventing minor deformations and displacements that may occur under external force, and ensuring that the connector 100 maintains a stable and reliable connection state under various working conditions.

[0042] The symmetrical design of the dual-sided locking mechanism enables the connector 100 to achieve uniform load distribution when subjected to external forces. When a pulling force is applied to the cable end, the external force is simultaneously transmitted to the first locking part 401 and the second locking part 431 through the first locking structure 30. The two locking parts, together with the integral structure formed by the connecting part 42, jointly bear the external force. The abutting action of the first abutting arm 312 and the first abutting part 314 further enhances the overall rigidity of the locking system, effectively preventing minor deformations and displacements that may occur under external forces.

[0043] Please continue reading. Figure 4 and Figure 5 In this embodiment of the application, the first guide arm 311 is further provided with a first puncture portion 313, which improves the connection stability and pull-out resistance of the connector 100.

[0044] The first piercing portion 313 is disposed on the side wall of the first guide arm 311. The geometry of the first piercing portion 313 is designed as a sharp wedge or cone structure, providing a piercing function. The first piercing portion 313 is made of the same high-strength metal material as the first guide arm 311, ensuring that the first piercing portion 313 has sufficient hardness and wear resistance. The surface of the first piercing portion 313 is precision machined, resulting in a smooth surface quality and precise geometric dimensions. When the connector 100 is locked, the first guide arm 311 enters the first guide slide 414 from the first guide port 416, and the first guide arm 311 is gradually guided along the predetermined trajectory of the first guide slide 414. During the movement of the first guide arm 311, the first piercing portion 313 moves together with the first guide arm 311, and the movement trajectory of the first piercing portion 313 is completely consistent with that of the first guide arm 311. As the first guide arm 311 is guided along the first guide slide 414 into the first locking cavity 415, the first piercing part 313 comes into contact with the first limiting plate 411. The first piercing part 313 abuts against the surface of the first limiting plate 411. During the contact, the sharp structure of the first piercing part 313 can slightly pierce the material surface of the first limiting plate 411, forming a microscopic mechanical engagement. The abutting action between the first piercing part 313 and the first limiting plate 411 generates significant frictional resistance, effectively preventing the first guide arm 311 from sliding backward under external force. When a pulling force is applied to the cable end, the mechanical engagement between the first piercing part 313 and the first limiting plate 411 can withstand a greater separation force, effectively preventing the connector 100 from accidentally disengaging.

[0045] Furthermore, based on the principle of bilateral symmetry design, the second guide arm 321 is correspondingly provided with a second piercing portion 323. The second piercing portion 323 and the first piercing portion 313 form a completely symmetrical functional configuration, achieving balanced performance and consistent operating characteristics of the locking mechanisms on both sides of the connector 100. The second piercing portion 323 is located at the corresponding position of the second guide arm 321, and its geometry, dimensions, and material properties are completely consistent with those of the first piercing portion 313. The second piercing portion 323 adopts the same wedge-shaped or conical structure design, possessing the same piercing capability and mechanical properties as the first piercing portion 313. The manufacturing process and quality standards of the second piercing portion 323 are unified with those of the first piercing portion 313, ensuring that the two piercing portions have the same service life and reliability level.

[0046] When the connector 100 performs a locking operation, the second guide arm 321 enters the second guide slide 436 from the second guide port 437 and is guided into the second locking cavity 438 along the predetermined path of the second guide slide 436. During the movement of the second guide arm 321, the second piercing part 323 moves synchronously with the second guide arm 321, and the movement trajectory of the second piercing part 323 completely coincides with that of the second guide arm 321.

[0047] When the second guide arm 321 is guided along the second guide slide 436 into the second locking cavity 438, the second piercing part 323 makes a pre-set contact with the third limiting plate 433. The second piercing part 323 abuts against the surface of the third limiting plate 433, and the sharp structure of the second piercing part 323 slightly pierces the material surface of the third limiting plate 433, forming a mechanical interlocking effect of the same degree as the first piercing part 313. The abutting action between the second piercing part 323 and the third limiting plate 433 generates equivalent frictional resistance, ensuring that the second guide arm 321 has the same anti-reverse slippage capability as the first guide arm 311.

[0048] In this embodiment, when a pulling force is applied to the cable end, the first piercing part 313 and the second piercing part 323 simultaneously bear the anti-separation load, and the load is evenly distributed through the integral structure formed by the connecting part 42. The mechanical engagement between the first piercing part 313 and the first limiting plate 411, and the mechanical engagement between the second piercing part 323 and the third limiting plate 433 work together to significantly improve the overall tensile strength of the connector 100. The double-sided piercing part configuration, together with the aforementioned double-sided abutment mechanism, forms a multi-locking protection system. The first piercing part 313, the first abutment part 314, the second piercing part 323, and the second abutment part 324 constitute a quadruple locking mechanism, where each locking element can function independently, while the elements cooperate with each other to enhance the overall effect. This multi-locking design ensures that the connector 100 maintains extremely high connection stability and reliability under various working environments and load conditions.

[0049] This application provides a connector 100, including a plug 10, a socket 20, a first locking structure 30, and a second locking structure 40. The first locking structure 30 is fixed to the plug 10, and the second locking structure 40 is sleeved on the socket 20. The second locking structure 40 includes a first locking arm 41, a connecting portion 42, and a second locking arm 43. The connecting portion 42 is connected to the first locking arm 41 and the second locking arm 43 respectively. The first locking arm 41 is provided with a first locking portion 401 and a first soldering surface 402. The first soldering surface 402 is used for soldering and fixing to a circuit board. The first locking part 401 cooperates with the first locking structure 30 to form a locking connection. When the connector 100 is subjected to pulling force from the cable end, the second locking structure 40 formed by the first locking arm 41, the connecting part 42, and the second locking arm 43 can effectively disperse and transfer stress, improving the overall deformation resistance of the socket 20. Furthermore, the connecting part 42 of the second locking structure 40 avoids local stress concentration. When subjected to lateral pressure, the load is distributed throughout the second locking structure 40 through the connecting part 42, making it less likely for the structure to reach the material yield strength, thereby effectively preventing permanent deformation. This structural improvement directly reduces the risk of yield deformation of the socket 20 shell and protects the integrity of the soldered connection with the circuit board.

[0050] This application also provides embodiments of mobile devices, which include the connector 100 described above. For embodiments of the mobile devices, please refer to the embodiments of the connector 100 described above, which will not be repeated here.
