[0005] To solve the above-mentioned technical problems, the present invention also adopts the following technical solution: a radio frequency connector assembly, including a mating male connector and a female connector, wherein the male connector is the aforementioned male connector.

[0006] The beneficial effects of this invention are as follows: In this male connector, each signal terminal is located in a different inner shell, and adjacent signal terminals are isolated by the side walls of two frame portions, which greatly improves the signal isolation effect and helps to improve the performance of the RF connector; no additional isolation plate is required between adjacent signal terminals, which not only facilitates the assembly of the male connector, but also ensures the structural stability of the male connector and eliminates the risk of isolation plate detachment; in addition, the male connector includes multiple independent signal transmission components, and designers can increase or decrease the number of signal transmission components according to actual application needs, which greatly enriches the diversity of the male connector and makes it applicable to more application scenarios, making it more practical.

[0016] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0017] Please refer to Figures 1 to 6 The male connector 1 includes a housing 11 and a plurality of signal transmission components 12. The signal transmission components 12 include an inner housing 121 and an insulating substrate 122 disposed in the inner housing 121. The insulating substrate 122 is provided with signal terminals 123. The inner housing 121 is installed and fixed inside the housing 11. The inner housing 121 includes a plate portion 1211 and a frame portion 1212 connected together. The plate portion 1211 is located at one end of the frame portion 1212 and covers at least a portion of the opening of the frame portion 1212. The insulating substrate 122 is located in the cavity enclosed by the plate portion 1211 and the frame portion 1212.

[0018] As can be seen from the above description, the beneficial effects of the present invention are as follows: In the male connector 1, each signal terminal 123 is located in a different inner shell 121, and two adjacent signal terminals 123 are isolated by the side walls of two frame portions 1212, which greatly improves the signal isolation effect and is conducive to improving the performance of the RF connector; no additional isolation plate is required between two adjacent signal terminals 123, which not only facilitates the assembly of the male connector 1, but also ensures the structural stability of the male connector 1 and eliminates the risk of isolation plate detachment; in addition, the male connector 1 includes multiple independent signal transmission components 12, and designers can increase or decrease the number of signal transmission components 12 according to actual application needs, which greatly enriches the diversity of the male connector 1, making it applicable to more application scenarios and more practical.

[0019] Furthermore, the signal transmission component 12 is snapped into the housing 11.

[0020] As can be seen from the above description, the connection between the signal transmission component 12 and the housing is simple and reliable, which facilitates the assembly and production of the male connector 1.

[0021] Furthermore, the plate portion 1211 has a fixing portion 12111 protruding outward relative to the frame portion 1212 on both sides, and the outer shell 11 is provided with a fixing structure that cooperates with the fixing portion 12111.

[0022] As can be seen from the above description, the snap-fit ​​structure between the signal transmission component 12 and the housing 11 is simple and easy to manufacture.

[0023] Furthermore, the outer shell 11 is provided with a limiting spoke 111, the limiting spoke 111 is located between two adjacent inner shells 121, and the limiting spoke 111 abuts against the fixing part 12111 on the two adjacent inner shells 121 respectively.

[0024] As described above, the limiting spokes 111 not only serve to contact and fix the two adjacent inner housings 121, but also allow the two adjacent inner housings 121 to maintain a preset relative positional relationship, thereby ensuring the structural stability and operational stability of the RF connector assembly.

[0025] Furthermore, there are two opposing limiting spokes 111 between two adjacent inner housings 121, and the two limiting spokes 111 are bent toward each other to abut against the fixing portions 12111 on the two inner housings 121.

[0026] As can be seen from the above description, the two opposing limiting spokes 111 can prevent the inner shell 121 from sliding within the outer shell 11, which helps to ensure the structural stability of the male connector 1.

[0027] Furthermore, the outer shell 11 includes a connected top wall 112 and a surrounding wall 113. The surrounding wall 113 is provided with a locking block 114 that cooperates with the fixing part 12111 located nearby. The plate part 1211 abuts against the inner side of the top wall 112.

[0028] As described above, the outer casing 11 has a simple structure and can effectively prevent internal signal leakage and external signal interference. The plate portion 1211 contacts the top wall 112, which allows the inner casing 121 to be well installed and positioned within the outer casing 11, and also allows the inner casing 121 and the outer casing 11 to have stable contact and conduction.

[0029] Furthermore, the frame portion 1212 has a groove 12123 on the surface near the plate portion 1211, and the plate portion 1211 and the groove 12123 together form a limiting groove. The insulating substrate 122 has a limiting protrusion 1222 that cooperates with the limiting groove.

[0030] As can be seen from the above description, the connection between the insulating substrate 122 and the inner shell 121 is stable, which helps to ensure the structural stability of the male connector 1.

[0031] Furthermore, the signal transmission component 12 also includes a coaxial cable 13, the core wire of the coaxial cable 13 being connected to the signal terminal 123, and the network cable of the coaxial cable 13 being connected to the inner housing 121; the inner housing 121 is provided with a first rivet 1215 for fixing the coaxial cable 13.

[0032] As described above, each signal transmission component 12 in the male connector 1 is independent of each other and can be manufactured separately. Therefore, when the first rivet 1215 is riveted and fixed to the coaxial line 13, there is no interference from other signal transmission components 12. Thus, the first rivet 1215 can be set as a complete annular rivet, instead of the crescent-shaped rivet in the prior art, which effectively improves the bonding force between the inner shell 121 and the coaxial line 13, thereby strengthening the structural stability of the male connector 1.

[0033] Furthermore, the outer casing 11 has a second rivet claw 115 that presses against the rivet claw.

[0034] As described above, the outer shell 11 is connected not only to the inner shell 121 but also to the coaxial line 13, which greatly reduces the risk of the outer shell 11 falling off and helps to further improve the structural stability of the male connector 1. Moreover, the second rivet 115 can also fasten the first rivet 1215, which helps to improve the bonding force between the inner shell 121 and the coaxial line 13.

[0035] The radio frequency connector assembly includes a mating male connector 1 and a female connector 2, wherein the male connector 1 is the aforementioned male connector 1.

[0036] Example 1

[0037] Please refer to Figures 1 to 6 Embodiment 1 of the present invention is as follows: Figure 1 As shown, an RF connector assembly is used to transmit RF signals. The RF connector assembly includes a mating male connector 1 and a female connector 2. The male connector 1 includes a signal terminal 123, and the female connector 2 includes a mating terminal. After the male connector 1 and the female connector 2 are connected and conductive, the signal terminal 123 and the mating terminal make contact and conduct.

[0038] Please combine Figure 1 and Figure 5 The male connector 1 includes a housing 11 and a plurality of signal transmission components 12. The signal transmission components 12 include an inner housing 121 and an insulating substrate 122 disposed in the inner housing 121. The insulating substrate 122 is provided with the signal terminals 123. The inner housing 121 is installed and fixed inside the outer housing 11. The inner housing 121 includes a plate portion 1211 and a frame portion 1212 connected together. The plate portion 1211 is located at one end of the frame portion 1212 and covers at least a portion of the opening of the frame portion 1212. The insulating substrate 122 is located in the cavity enclosed by the plate portion 1211 and the frame portion 1212.

[0039] Please combine Figure 5 and Figure 6 In this embodiment, the frame portion 1212 includes a base portion 12121. One end of the plate portion 1211 is connected to the base portion 12121 via a bending portion 1213. The other end of the plate portion 1211 has L-shaped protective portions 1214 on both sides, which are arranged opposite to each other. The plate portion 1211 and the two protective portions 1214 enclose a protective cavity. One end of the insulating substrate 122 is located within the protective cavity. Alternatively, the protective cavity can be considered a portion of the chamber. Arm portions 12122 are connected to both sides of the base portion 12121, and the two arm portions 12122 are symmetrically arranged. The end of the arm portion 12122 away from the base portion 12121 extends into the protective cavity. The protective part 1214 can effectively protect the end of the arm 12122 away from the base 12121, preventing the arm 12122 from being accidentally pulled outward, which would cause the inner shell 121 to fail. This helps to ensure the structural stability of the male connector 1 and extend the service life of the male connector 1.

[0040] Preferably, the insulating substrate 122 has a boss 1221 protruding away from the plate portion 1211. The boss 1221 is located within the protective cavity, and the ends of the two arms 12122 extending into the protective cavity are located on both sides of the boss 1221. The surface of the boss 1221 away from the plate portion 1211 abuts against the protective portion 1214. The presence of the boss 1221 not only improves the structural strength of the insulating substrate 122 itself, but also allows the protective portion 1214 to abut against the insulating substrate 122, thereby better fixing the insulating substrate 122, reducing displacement and shaking of the insulating substrate 122 relative to the inner shell 121, and helping to ensure the structural stability of the male connector 1.

[0041] For ease of manufacturing, preferably, the signal transmission component 12 is snapped into the outer casing 11. In other embodiments, the inner casing 121 and the outer casing 11 may also be welded together.

[0042] Please combine Figure 3 and Figure 5 The plate portion 1211 has fixing portions 12111 protruding outward relative to the frame portion 1212 on both sides, and the outer shell 11 is provided with a fixing structure that cooperates with the fixing portions 12111. In this embodiment, the fixing portion 12111 is L-shaped. More specifically, the side of the plate portion 1211 extends outward at one end and then bends away from the side close to the frame portion 1212 to form the L-shaped fixing portion 12111, and the fixing portion 12111 is located outside the frame portion 1212.

[0043] Please combine Figures 2 to 4 The outer shell 11 is provided with limiting spokes 111, which are located between two adjacent inner shells 121. The limiting spokes 111 abut against the fixing parts 12111 on the two adjacent inner shells 121 respectively. That is, the adjacent inner shells 121 are connected and fixed to the outer shell 11 by the limiting spokes 111 at their close positions. This allows the spacing between the two adjacent inner shells 121 to be set smaller, or even the fixing parts 12111 of the two adjacent inner shells 121 to abut against each other. In this way, the volume of the male connector 1 can be effectively reduced, so that the RF connector assembly can adapt to the trend of miniaturization of electronic devices.

[0044] To improve the fixing effect of the outer shell 11 on the inner shell 121, it is preferable that two limiting spokes 111 are arranged opposite to each other between two adjacent inner shells 121, and the two limiting spokes 111 are bent toward each other to abut against the fixing part 12111 on the two inner shells 121.

[0045] Please combine Figure 2 , Figure 4 and Figure 5 The outer shell 11 includes a connected top wall 112 and a surrounding wall 113. The surrounding wall 113 is provided with a locking block 114 that engages with the nearby fixing part 12111. The plate part 1211 abuts against the inner side of the top wall 112. In this embodiment, the fixing parts 12111 on the opposite sides of the two inner shells 121 engage with the locking blocks 114 on the outer shell 11.

[0046] It is easy to understand that the locking block 114 and the limiting spoke 111 are the fixing structures on the outer shell 11 of this embodiment.

[0047] like Figure 5 and Figure 6 As shown, the frame portion 1212 has a groove 12123 on its surface near the plate portion 1211. The surface of the plate portion 1211 near the frame portion 1212 and the groove 12123 form a limiting groove. The insulating substrate 122 has a limiting protrusion 1222 that mates with the limiting groove. The L-shaped fixing portion 12111 can, to a certain extent, shield the limiting groove, thereby preventing the limiting protrusion 1222 from being accidentally damaged during the transmission of the signal transmission component 12 and during the assembly of the male connector 1, which would reduce the bonding strength between the insulating substrate 122 and the inner shell 121 and help ensure the structural stability of the male connector 1.

[0048] like Figure 3 As shown, the signal transmission component 12 further includes a coaxial cable 13, the core wire of the coaxial cable 13 is connected to the signal terminal 123, and the network cable of the coaxial cable 13 is connected to the inner housing 121; the inner housing 121 is provided with a first rivet 1215 for fixing the coaxial cable 13.

[0049] In a preferred embodiment, the outer casing 11 has a second rivet claw 115 that presses against the rivet claw.

[0050] In summary, the male connector and RF connector assembly provided by this invention have the following characteristics: each signal terminal in the male connector is located in a different inner shell, and adjacent signal terminals are isolated by the side walls of two frame portions, which greatly improves the signal isolation effect and is beneficial to improving the performance of the RF connector; no additional isolation plate is required between adjacent signal terminals, which not only facilitates the assembly of the male connector but also ensures the structural stability of the male connector and eliminates the risk of isolation plate detachment; in addition, the male connector includes multiple independent signal transmission components, and designers can increase or decrease the number of signal transmission components according to actual application needs, greatly enriching the diversity of the male connector and enabling it to be applied to more application scenarios, making it more practical.

[0051] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
