Directional terms mentioned in the present invention, such as "upper", "lower", "front", "back", "left", "right", "top", "bottom", etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, but are not used to limit the present invention.

[0057] The RF connector of the present invention can solve the problem of impedance discontinuity caused by the obvious high impedance of the existing structure, which in turn causes the problem of increased signal attenuation and reflection in higher-frequency signal transmission. The RF connector of the present invention is particularly suitable for the transmission of high-frequency signals and can reach a transmission frequency of 20 GHz.

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

[0059] The insulating base 10 includes at least one channel 11 for fixing the central conductor assembly 20. The insulating base 10 also 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 shown in FIG. Fig.12 As 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 to limit the movement of the central conductor assembly 20 .

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

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

[0063] like Figure 4 and Figure 6As shown, the inner conductor 21 has a contact end 210 at the front end and a connection end 211 at the rear end, wherein the contact end 210 is used to connect 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 invention 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 connecting end 211 of the inner conductor 21 is connected to the center wire 250 of the cable 25a and is crimped and fixed by a conductive sleeve 26. Furthermore, the conductive sleeve 26 is crimped on the shielding layer of the cable 25a.

[0065] like Figure 4 and Figure 6 As shown, 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 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 to the front support section 221 of the insulating support 22, and the connection end 211 of the inner conductor 21 extends to the rear support section 222 of the insulating support 22. In addition, the inner conductor 21 can be provided with a protrusion 212, which is pressed against the inner wall of the central cavity 220, so that the inner conductor 21 is fixed in the central cavity 220.

[0066] like Figure 4 , Figure 5 , Figure 6 As shown, the inner shielding ring 23 is arranged on the outer circumferential surface of the insulating support member 22 and is located on the front support section 221. Specifically, the inner shielding ring 23 is embedded in the front support section 221 and exposed on the outer circumferential surface of the insulating support member 22. Compared with the existing design, the front support section 221 of the insulating support member 22 can be thinner. Through this design, the impedance of the RF connector 1 of the present invention can be effectively controlled. Please describe the specific details later. In the present embodiment, the inner shielding ring 23 is provided with a locking portion 230, and a mating portion 223 is provided on the outer circumferential surface of the insulating support member 22. The inner shielding ring 23 is fixed to the outer circumferential surface of the front support section 221 of the insulating support member 22 by the engagement of the locking portion 230 with the mating portion 223.

[0067] In this embodiment, the locking portion 230 of the inner shielding ring 23 can be a stamped sheet that is bent toward the inner side of the inner shielding ring 23, and the matching portion 223 of the insulating support 22 is a recess, and the sheet can be inserted into the recess 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 segment 221 , and the inner shielding ring 23 may be installed on the front support segment 221 ; or the inner shielding ring 23 may be fixed to the front support segment 221 by injection molding.

[0069] In this embodiment, the inner shield ring 23 is an independent member.

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

[0071] like Figure 4 The outer conductor 24 is disposed on the periphery of 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, such as Fig.14 , but at the same time, the outer shielding shell 43 will also be connected to the inner shielding ring 23, thereby reducing the shielding distance between the outer shielding shell 43 and the inner conductor 21, and by adjusting the shielding distance and / or the thickness of the front support section 221 of the insulating support member 22, the RF connector 1 of the present invention can obtain a desired impedance value (for example, 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, the inner shielding ring 23 is set on the front support section 221 of the insulating support member 22 to control the thickness of the front support section 221, thereby controlling the impedance of the RF connector 1 of the present invention.

[0072] In addition, the outer conductor 24 and the inner shielding ring 23 are connected to the outer shielding shell 43 of the butt conductor assembly 40, such as Fig.14 , thus forming a complete shielding body 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 member 22 and the inner shielding ring 23, so that the annular insertion space 240 is located between the front conductive portion 241 of the outer conductor 24 and the inner shielding ring 23 for connecting the outer shielding shell 43 (see FIG. Fig.10 and Fig.14) is inserted therein to form a shield connection. In this embodiment, the front conductive portion 241 has at least one elastic arm 2410, and at least a portion of the elastic arm 2410 protrudes toward the insertion space 240. In this embodiment, the front conductive portion 241 is claw-shaped and has a plurality of elastic arms 2410 for clamping the outer shield shell 43 together.

[0074] In this embodiment, the outer conductor 24 further has an intermediate conductive portion 243, whose inner diameter is smaller than the inner diameter of the front conductive portion 241 and the inner diameter of the rear conductive portion 242. The intermediate conductive portion 243 surrounds and is crimped on the insulating support 22, especially between the front support segment 221 and the rear support segment 222 of the insulating support 22, thereby limiting the movement of the outer conductor 24. The rear conductive portion 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, which is used as a male end connector docking with the RF connector 1 of the present invention, includes a docking base 30 and at least one docking conductor assembly 40. The docking base 30 forms a cavity 31, and the docking conductor assembly 40 is fixed in the docking base 30 and extends into the cavity 31.

[0076] like Figure 7 and Figure 8 As shown, the docking base 30 includes a locking structure 32, which is disposed on the top surface of the docking base 30. Fig.12 As 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 a docking state. Figure 8 As shown, the docking base 30 further includes a pair of inserting members 33 inserted into the slots 34 of the docking base 30 to limit 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 four center conductor assemblies 20 .

[0078] Please refer to Fig. 9 , Fig.10 , Fig.11 The mating conductor assembly 40 of the mating connector 2 shown 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] like Fig.10 , Fig.11As shown, the center pin 41 has an insertion end 410 located at the front end and a fixed end 411 located at the rear end, wherein the insertion end 410 extends out of the front end of the insulating shell 42 to connect with the inner conductor 21 of the RF connector 1 of the present invention; specifically, the insertion end 410 can be inserted into the central cavity 220 of the insulating support 22 and enter the tubular inner conductor 21 (see Fig.14 ), and forms electrical contact with the contact end 210. The fixed end 411 is connected to an electrical component, such as a cable 25b.

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

[0081] like Fig.10 As shown, the outer shielding shell 43 is sleeved on the insulating shell 42 and forms a matching space 430 located in front of the insulating shell 42. The insertion end 410 of the center pin 41 extends out of the insulating shell 42 and is exposed in the matching space 430. In other words, the matching space 430 surrounds the insertion end 410. The matching space 430 is used to accommodate the front support section 221 and the inner shielding ring 23 of the insulating support member 22 of the RF connector 1 when docking with the RF connector 1 of the present invention.

[0082] Please refer to Figure 12 to Figure 14 The connector assembly 3 of the present invention shown in the figure comprises a radio frequency connector 1 and a docking connector 2. Fig.12 As shown, the insulating base 10 of the RF connector 1 of the present invention 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 a docking state.

[0083] like Fig.13 and Fig.14 As shown, the central conductor assembly 20 and the butt conductor assembly 40 are in a butt-jointed state.

[0084] In detail, Fig.14 As shown, the central pin 41 is inserted into the central cavity 220 of the insulating support 22 (see reference numerals). Figure 4 ), enters the inner conductor 21, and forms electrical contact with the contact end 210 of the inner conductor 21 to transmit signals. The outer shield shell 43 is inserted into the annular insertion space 240 (see reference numerals) between the outer conductor 24 and the inner shield ring 23. Figure 4), accordingly, the front support section 221 of the insulating support member 22 and the inner shielding ring 23 enter the matching 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 will be crimped on the outer shielding shell 43, which can better ensure that the contact between the two is stable. The connector assembly 3 of the present invention is particularly suitable for the transmission of high-frequency signals, and can reach a transmission frequency of 20GHz.

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