[0056] The following description of the embodiments refers to the attached drawings, which illustrate specific embodiments in which the present invention can be implemented. The directional terms mentioned in the present invention, such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are for explaining and understanding the present invention, rather than for limiting the present invention.

[0057] The RF connector of the present invention can solve the problem that the impedance discontinuity caused by the significantly high impedance in the existing structure leads to an increase in signal attenuation and reflection in the transmission of higher-frequency signals. The RF connector of the present invention is particularly suitable for the transmission of high-frequency signals and can achieve a transmission frequency of 20 GHz.

[0058] Please refer to Figure 1 and Figure 2 As shown, the RF connector 1 of the present invention includes an insulating base 10 and at least one center conductor assembly 20 disposed in the insulating base 10.

[0059] The insulating base 10 includes at least one channel 11 for fixing the center conductor assembly 20. The insulating base 10 further includes a latch structure 12 disposed on the top surface of the insulating base 10. When the RF connector 1 is docked with the docking connector 2, as Figure 12 shown, the latch structure 12 locks the docking connector 2.

[0060] In this embodiment, the RF connector 1 further includes a pair of fixing elements 13 installed in the grooves 14 on both sides of the insulating base 10 for restricting the movement of the center conductor assembly 20.

[0061] In this embodiment, the RF connector 1 of the present invention includes four center conductor assemblies 20, and the present invention does not limit the number of the center conductor assemblies 20.

[0062] The center conductor assembly 20 of the RF connector 1 of the present invention is disposed in the channel 11 of the insulating base 10. Please refer to Figures 3 to 6 the center conductor assembly 20 of the RF connector 1 of the present invention as shown, which includes an inner conductor 21, an insulating support 22 for supporting the inner conductor 21, an inner shielding ring 23 fixed on the outer peripheral surface of the insulating support 22, and an outer conductor 24 surrounding the insulating support 22.

[0063] AsFigure 4 and Figure 6 As shown in Figure 6 , the inner conductor 21 has a contact end 210 at the front end and a connection end 211 at the rear end. The contact end 210 is used to dock with the docking conductor assembly 40 of the docking connector 2, and the connection end 211 is connected to an electrical component, such as a cable 25a. In other embodiments, the electrical component can be a circuit board or other components.

[0064] In this embodiment, the inner conductor 21 is a hollow tube, and its contact end 210 is claw-shaped and can be elastically clamped. For example, when the RF connector 1 of the present utility model is docked with the docking connector 2, the center pin 41 of the docking conductor assembly 40 is inserted into the contact end 210 of the inner conductor 21, and the contact end 210 elastically clamps the center pin 41, thereby forming a stable electrical contact effect. The connection end 211 of the inner conductor 21 is connected to the center conductor 250 of the cable 25a and is fixed by a conductive sleeve 26. Further, the conductive sleeve 26 is crimped on the shielding layer of the cable 25a.

[0065] As Figure 4 and Figure 6 shown in Figure 6 , the insulating support 22 has a central cavity 220 for wrapping or accommodating the inner conductor 21. The insulating support 22 includes a front support section 221 and a rear support section 222, and the central cavity 220 penetrates through the front support section 221 and the rear support section 222 of the insulating support 22. Among them, the contact end 210 of the inner conductor 21 extends towards the front support section 221 of the insulating support 22, and the connection end 211 of the inner conductor 21 extends towards the rear support section 222 of the insulating support 22. In addition, the inner conductor 21 can be provided with a protrusion 212, and the inner conductor 21 is fixed in the central cavity 220 by pressing against the inner wall of the central cavity 220 through the protrusion.

[0066] As Figure 4 , Figure 5 , Figure 6 shown in Figure 4 , Figure 5 , Figure 6 , the inner shielding ring 23 is disposed on the outer peripheral surface of the insulating support 22 and is located in the front support section 221. Specifically, the inner shielding ring 23 is embedded in the front support section 221 and is exposed on the outer peripheral surface of the insulating support 22. Compared with the existing design, the front support section 221 of the insulating support 22 can be thinned. Through this design, the impedance of the RF connector 1 of the present utility model can be effectively controlled. Specific details will be described later. In this embodiment, the inner shielding ring 23 is provided with a locking portion 230, and a mating portion 223 is provided on the outer peripheral surface of the insulating support 22. The inner shielding ring 23 is fixed to the outer peripheral surface of the front support section 221 of the insulating support 22 by the engagement of the locking portion 230 and the mating portion 223.

[0067] In this embodiment, the locking portion 230 of the inner shielding ring 23 can be a sheet body formed by stamping and bent towards the inner side of the inner shielding ring 23, while the mating portion 223 of the insulating support 22 is a notch, and the sheet body can be snapped into the notch to limit the movement of the inner shielding ring 23.

[0068] In addition, it should be noted that the inner shielding ring 23 is embedded in the front support section 221. It can be that the inner shielding ring 23 is installed on the front support section 221, or it can be that the inner shielding ring 23 is fixed to the front support section 221 by injection molding.

[0069] In this embodiment, the inner shielding ring 23 is an independent component.

[0070] In other embodiments, the inner shielding ring 23 may not be an independent component, and it may be a metal layer or metal surface formed on the outer peripheral surface of the insulating support 22 by electroplating or other means.

[0071] Such as Figure 4 , the outer conductor 24 is disposed around the insulating support 22, and an annular insertion space 240 is formed between the outer conductor 24 and the front support section 221 of the insulating support 22. When the RF connector 1 of the present invention is docked with the docking connector 2, the outer conductor 24 is connected to the outer shielding shell 43 of the docking conductor assembly 40 of the docking connector 2, as Figure 14 , but at the same time, the outer shielding shell 43 will also form a connection with the inner shielding ring 23, thereby reducing the shielding distance between the outer shielding shell 43 and the inner conductor 21. Moreover, by adjusting the shielding distance or / and the thickness of the front support section 221 of the insulating support 22, the RF connector 1 of the present invention can obtain the desired impedance value (such as 50 ohms, 70 ohms or other values). That is to say, at the beginning of the design of the RF connector of the present invention, by providing the inner shielding ring 23 on the front support section 221 of the insulating support 22 to control the thickness of the front support section 221, the impedance of the RF connector 1 of the present invention is controlled.

[0072] In addition, by connecting the outer conductor 24, the inner shielding ring 23 and the outer shielding shell 43 of the docking conductor assembly 40, as Figure 14 , a complete shielding body is formed to ensure high-quality signal transmission.

[0073] Specifically, in this embodiment, the outer conductor 24 has a front conductive portion 241 and a rear conductive portion 242. The front conductive portion 241 surrounds the front support section 221 of the insulating support 22 and the inner shielding ring 23. Therefore, the annular insertion space 240 is located between the front conductive portion 241 of the outer conductor 24 and the inner shielding ring 23, and is used for the outer shielding shell 43 of the docking conductor assembly 40 (see Figure 10 and Figure 14)It is inserted therein to form a shielding connection. In this embodiment, the front conductive part 241 has at least one elastic arm 2410, and at least a part of the elastic arm 2410 protrudes towards the insertion space 240. In this embodiment, the front conductive part 241 is claw-shaped and has a plurality of elastic arms 2410 for jointly clamping the outer shielding shell 43.

[0074] In this embodiment, the outer conductor 24 further has an intermediate conductive part 243, whose inner diameter is smaller than that of the front conductive part 241 and also smaller than that of the rear conductive part 242. The intermediate conductive part 243 surrounds and is crimped on the insulating support 22, especially between the front support section 221 and the rear support section 222 of the insulating support 22, thereby restricting the movement of the outer conductor 24. The rear conductive part 242 of the outer conductor 24 surrounds and is crimped on the conductive sleeve 26, thereby further fixing the cable 25a and further improving the shielding effect.

[0075] Please refer to Figure 7 、 Figure 8 the docking connector 2 shown in

[0076] As Figure 7 and Figure 8 shown, the docking base 30 includes a locking structure 32 provided on the top surface of the docking base 30. As Figure 12 shown, when the docking connector 2 is docked with the RF connector 1 of the present invention, the locking structure 32 of the docking base 30 matches the latch structure 12 of the insulating base 10, thereby locking the docking connector 2 and the RF connector 1 in the docking state. In addition, as Figure 8 shown, the docking base 30 further includes a pair of inserts 33 inserted into the card slots 34 of the docking base 30 for restricting the movement of the docking conductor assembly 40.

[0077] In this embodiment, the docking connector 2 includes four docking conductor assemblies 40 to correspond to the four center conductor assemblies 20.

[0078] Please refer to Figure 9 、 Figure 10 、 Figure 11 shown, the docking conductor assembly 40 of the docking connector 2 includes a center pin 41, an insulating shell 42 for fixing the center pin 41, and an outer shielding shell 43 surrounding the insulating shell 42.

[0079] As Figure 10 、 Figure 11As shown, the center pin 41 has an insertion end 410 at the front end and a fixed end 411 at the rear end. The insertion end 410 extends out of the front end of the insulating housing 42 and is used to dock with the inner conductor 21 of the RF connector 1 of the present utility model. Specifically, the insertion end 410 can be inserted into the central cavity 220 of the insulating support 22, enter the tubular inner conductor 21 (see Figure 14 ), and form electrical contact with the contact end 210. The fixed end 411 is connected to an electrical component, such as the cable 25b.

[0080] As Figure 10 shown, the insulating housing 42 is used to accommodate and fix the center pin 41.

[0081] As Figure 10 shown, the outer shielding housing 43 is sleeved on the insulating housing 42 and forms a mating space 430 in front of the insulating housing 42. The insertion end 410 of the center pin 41 extends out of the insulating housing 42 and is exposed in the mating space 430. That is to say, the mating space 430 surrounds the insertion end 410. The mating space 430 is used to accommodate the front support section 221 and the inner shielding ring 23 of the insulating support 22 of the RF connector 1 when docking with the RF connector 1 of the present utility model.

[0082] Please refer to Figures 12 to 14 the connector assembly 3 of the present utility model shown. The connector assembly 3 includes the RF connector 1 and the docking connector 2. As Figure 12 shown, the insulating base 10 of the RF connector 1 of the present utility model enters the cavity 31 of the docking base 30 of the docking connector 2, and the locking structure 32 of the docking base 30 matches the latch structure 12 of the insulating base 10, thereby locking the connector assembly 3 in the docking and mating state.

[0083] As Figure 13 and Figure 14 shown, the central conductor assembly 20 and the docking conductor assembly 40 form a docking and mating state.

[0084] Specifically, as Figure 14 shown, the center pin 41 is inserted into the central cavity 220 of the insulating support 22 (the label is shown in Figure 4 ), enters the inner conductor 21, forms electrical contact with the contact end 210 of the inner conductor 21, and conducts signal transmission. The outer shielding housing 43 is inserted into the annular insertion space 240 between the outer conductor 24 and the inner shielding ring 23 (the label is shown in Figure 4) Accordingly, the front support section 221 of the insulating support 22 and the inner shielding ring 23 enter the fitting space 430 of the outer shielding shell 43. At this time, the outer conductor 24 contacts the outer shielding shell 43, and the outer shielding shell 43 contacts the inner shielding ring 23, thereby forming a complete shielding path, which can ensure better communication quality during high-frequency signal transmission. In particular, the elastic arm 2410 of the outer conductor 24 is crimped on the outer shielding shell 43, which can further ensure stable contact between the two. The connector assembly 3 of the present utility model is particularly suitable for high-frequency signal transmission and can reach a transmission frequency of 20 GHz.

[0085] In summary, by providing the inner shielding ring 23 on the insulating support 22, the RF connector 1 of the present utility model can control the impedance between the inner conductor 21 and the outer shielding shell 43 of the docking conductor assembly 40, so as to solve the problem of impedance discontinuity caused by significantly high impedance in the existing structure, and further the problem of increased signal attenuation and reflection in the transmission of higher-frequency signals. The RF connector 1 and the connector assembly 3 of the present utility model are particularly suitable for high-frequency signal transmission and can reach a transmission frequency of 20 GHz.
