[0037] In some cases, a connector can be coupled between a signal sending component and a signal receiving component so that the signal can be transmitted from the signal sending component to the signal receiving component via the connector. The outer conductor of the connector and the signal receiving component are usually connected by glue at the contacting edges to form a glue ring, which is convenient for providing signal shielding effect and reducing signal leakage through the glue ring. However, in order to form the glue ring, a circle of more connection points needs to be set between the outer conductor and the signal receiving component, resulting in numerous and complicated glue processes, resulting in poor assembly convenience and efficiency between the connector and the signal receiving component. In addition, the signal shielding effect between the connector and the signal receiving component based on the glue ring is not good.

[0038] The embodiments provided in this application will solve the above-mentioned problems.

[0039] In order to illustrate the technical solution provided by the present application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0040] See also Figure 1 , Figure 2 , Figure 3 Some embodiments of the present application provide a connector 10, including an inner conductor 11 and an outer conductor 12, the inner conductor 11 is used to couple and connect between a signal sending component 20 and a signal receiving component 30; the outer conductor 12 is sleeved on the outer circumference of the inner conductor 11, the outer conductor 12 includes an outer cylinder 121 and a shielding ring 122 connected to one end of the outer cylinder 121, the end of the outer cylinder 121 away from the shielding ring 122 is connected and fixed to the signal sending component 20, and the shielding ring 122 can be deformed under force and elastically press against the signal receiving component 30.

[0041] It should be noted that the connector 10 is used to transmit signals and energy from the signal sending component 20 to the signal receiving component 30. The signal sending component 20 may be, but not limited to, a filter, an antenna, AFU (Antenna Filter Units, antenna filter integrated), etc. The signal receiving component 30 may be, but not limited to, a power amplifier board, a radio frequency board, a modem, etc.

[0042] It should also be noted that one end of the inner conductor 11 is coupled to the signal sending element 20 (can be an inductive coupling connection or a capacitive coupling connection) to realize the introduction of signals and energy from the signal sending element 20; the other end of the inner conductor 11 is coupled to the signal receiving element 30 (can be an inductive coupling connection or a capacitive coupling connection) to realize the output of signals and energy to the signal receiving element 30. That is, the connector 10 can transmit signals and energy from the signal sending element 20 to the signal receiving element 30 via the inner conductor 11.

[0043] The outer conductor 12 is cylindrical in shape and is sleeved on the outer circumference of the inner conductor 11. When the inner conductor 11 transmits signals and energy, the outer conductor 12 can play a signal shielding role to prevent signal leakage and block external signals from interfering with the inner conductor 11. The inner wall of the outer conductor 12 is spaced from the outer wall of the inner conductor 11 so that the outer conductor 12 and the inner conductor 11 are not in contact and conduct. Figure 2 , Figure 3 As shown, in some embodiments, the connector 10 further includes an insulator 13, the insulator 13 is installed in the outer conductor 12, the inner conductor 11 is passed through the insulator 13, and both opposite ends of the inner conductor 11 pass through the insulator 13. The insulator 13 provides a fixing and supporting function for the inner conductor 11, so that the outer conductor 12, the insulator 13 and the inner conductor 11 are relatively fixed, and the insulator 13 is also insulated and blocked between the inner conductor 11 and the outer conductor 12. Of course, in other embodiments, the outer conductor 12 and the inner conductor 11 can be stabilized in relative installation position and relative installation state by other components, for example, the outer conductor 12 and the inner conductor 11 can be fixed relative to the signal sending component 20 respectively.

[0044] The outer conductor 12 includes an outer cylinder 121 and a shielding ring 122. The outer cylinder 121 is the main body of the outer conductor 12, and one end of the outer cylinder 121 is connected and fixed to the signal sending member 20, so that the outer conductor 12 is supported by the signal sending member 20 to stabilize the installation position and installation state, wherein the connection and fixing method between the outer cylinder 121 and the signal sending member 20 can be adopted but not limited to the use of plug-in, crimping, threaded connection, welding, clamping, bonding and the like.

[0045] The shielding ring 122 is connected to the end of the outer cylinder 121 away from the signal sending element 20, that is, connected to the end of the outer cylinder 121 close to the signal receiving element 30, so that the shielding ring 122 is supported and fixed by the outer cylinder 121. The shielding ring 122 and the outer cylinder 121 can be connected as one piece or separately, and the separate connection method can be, but is not limited to, welding, fusion, etc.

[0046] When the connector 10 is assembled between the signal transmitting component 20 and the signal receiving component 30, the shielding ring 122 can be pressed against the signal receiving component 30, and can be elastically deformed outwardly due to the pressing force, thereby elastically pressing against the signal receiving component 30. Based on this, the outer conductor 12 can be tightly pressed against the signal receiving component 30 via the shielding ring 122, so as to provide a signal shielding effect between the outer conductor 12 and the signal receiving component 30 via the shielding ring 122 to prevent signal leakage.

[0047] In summary, the connector 10 provided in the embodiment of the present application can be coupled and connected between the signal sending component 20 and the signal receiving component 30 via the inner conductor 11, so as to transmit the signal and energy from the signal sending component 20 to the signal receiving component 30; and can also play a signal shielding role in the process of the inner conductor 11 transmitting the signal and energy through the outer conductor 12 sleeved on the outer periphery of the inner conductor 11, so as to prevent signal leakage and block the external signal from interfering with the inner conductor 11. In particular, the outer conductor 12 of the connector 10 can be directly elastically pressed against the signal receiving component 30 through the shielding ring 122 connected to one end of the outer cylinder 121, so as to quickly and reliably press the signal receiving component 30 tightly, thereby playing a reliable and effective signal shielding role between the outer conductor 12 and the signal receiving component 30, and reliably preventing the signal from leaking from between the outer conductor 12 and the signal receiving component 30. In this way, the structure of the connector 10 can be simplified and optimized, the assembly process between the connector 10 and the signal receiving component 30 can be simplified, the assembly convenience and efficiency between the connector 10 and the signal receiving component 30 can be improved, and the signal shielding effect between the outer conductor 12 of the connector 10 and the signal receiving component 30 based on the shielding ring 122 can be optimized.

[0048] See also Figure 1 , Figure 2 , Figure 3 In some embodiments of the present application, the shielding ring 122 is integrally connected to the outer cylinder 121. That is, the outer conductor 12 is an integrated structure, an integrally molded structure.

[0049] By adopting the above scheme, by making the shielding ring 122 and the outer cylinder 121 integrally formed and integrally connected, the assembly process between the shielding ring 122 and the outer cylinder 121 can be saved, thereby improving the assembly convenience and assembly efficiency of the connector 10. In addition, the connection strength, connection reliability and connection stability between the shielding ring 122 and the outer cylinder 121 can be improved, the risk of the shielding ring 122 falling off the outer cylinder 121 can be reduced, and the structural reliability of the outer conductor 12 can be improved, thereby improving the signal shielding effect of the shielding ring 122 between the outer conductor 12 and the signal receiving element 30, and improving the use reliability and service life of the shielding ring 122, the outer conductor 12 and the connector 10. In addition, the processing cost, assembly cost and other costs can be reduced.

[0050] See also Figure 1 , Figure 2 , Figure 3 In some embodiments of the present application, the shielding ring 122 is provided with at least one truncation groove 1221 in its circumference.

[0051] It should be noted that the shielding ring 122 is provided with at least one truncation groove 1221. In the case where there are multiple truncation grooves 1221, the multiple truncation grooves 1221 are arranged at intervals along the circumference of the shielding ring 122 (they can be arranged at equal intervals or at unequal intervals); the multiple truncation grooves 1221 can be arranged identically or unequally. The truncation groove 1221 penetrates the annular wall of the shielding ring 122 and is connected to the end face of the shielding ring 122 away from the outer cylinder 121 to cut off the complete continuity of the shielding ring 122 in the circumferential direction. In addition, the shape and size of the truncation groove 1221 can be set as required.

[0052] By adopting the above scheme, the shielding ring 122 can be completely continuous in the circumferential direction through at least one truncation groove 1221 without affecting the shielding ring 122 from forming a shielding network, and a deformation space can be provided for the shielding ring 122. Based on this, the deformation resistance of the shielding ring 122 can be reduced, the elastic deformation capacity of the shielding ring 122 under stress can be optimized, and the shielding ring 122 can be conveniently and reliably elastically pressed against the signal receiving part 30, thereby improving the assembly convenience and assembly efficiency between the connector 10 and the signal receiving part 30, and optimizing the signal shielding effect between the outer conductor 12 of the connector 10 and the signal receiving part 30 based on the shielding ring 122.

[0053] Of course, in other embodiments, the shielding ring 122 may be made of an elastic material and have elasticity, for example, the shielding ring 122 may be made of an elastic metal material, or the shielding ring 122 may be made of an elastic material and covered with a metal layer, etc. In this case, the shielding ring 122 may omit the truncation groove 1221 as required.

[0054] See also Figure 1 , Figure 2 , Figure 3 In some embodiments of the present application, the truncation groove 1221 extends from the end surface of the shielding ring 122 away from the outer cylinder 121 to the end surface of the shielding ring 122 close to the outer cylinder 121 .

[0055] By adopting the above scheme, by extending the truncation groove 1221 from the end face of the shielding ring 122 away from the outer cylinder 121 to the end face of the shielding ring 122 close to the outer cylinder 121, the shielding ring 122 can be divided into multiple petals due to the truncation groove 1221. Based on this, each petal of the shielding ring 122 can be relatively independently adaptively elastically deformed according to its own stress conditions, so that the shielding ring 122 can evenly distribute stress when subjected to stress, and the stress concentration phenomenon can be reduced, thereby optimizing the elastic deformation ability of the shielding ring 122, and enabling the shielding ring 122 to quickly and reliably elastically press the signal receiving component 30, and improve the fit between each petal of the shielding ring 122 and the signal receiving component 30, thereby improving the assembly convenience and efficiency between the connector 10 and the signal receiving component 30, and optimizing the signal shielding effect between the outer conductor 12 of the connector 10 and the signal receiving component 30 based on the shielding ring 122.

[0056] This embodiment is particularly suitable for implementation together with "the shielding ring 122 is integrally connected to the outer cylinder 121". In the case where the shielding ring 122 is separately connected to the outer cylinder 121: if the truncated groove 1221 extends from the end face of the shielding ring 122 away from the outer cylinder 121 to the end face of the shielding ring 122 close to the outer cylinder 121, each petal of the shielding ring 122 needs to be separately connected to the end of the outer cylinder 121, and the connection operation is cumbersome and complicated, and it is difficult to ensure the accuracy of the connection position; if the truncated groove 1221 does not extend from the end face of the shielding ring 122 away from the outer cylinder 121 to the end face of the shielding ring 122 close to the outer cylinder 121, although the shielding ring 122 can maintain the integrity of the structure, the elastic deformation ability will be deteriorated, and the elastic pressing effect of the shielding ring 122 on the signal receiving component 30 will be deteriorated. In this embodiment, on the basis of “the shielding ring 122 and the outer cylinder body 121 being integrally connected”, the truncation groove 1221 can be extended from the end face of the shielding ring 122 away from the outer cylinder body 121 to the end face of the shielding ring 122 close to the outer cylinder body 121, thereby ensuring the elastic deformation effect and elastic pressure effect of the shielding ring 122, as well as the connection convenience and positioning accuracy of the shielding ring 122 and the outer cylinder body 121.

[0057] Of course, in other embodiments, the extension length of the truncation groove 1221 along the axial direction of the shielding ring 122 can be set as needed.

[0058] See also Figure 1 , Figure 2 , Figure 3 In some embodiments of the present application, the shielding ring 122 includes a first ring portion 1222 and a second ring portion 1223. The first ring portion 1222 is connected to the outer cylinder body 121 and extends in a direction away from the outer cylinder body 121. The second ring portion 1223 is connected to one end of the first ring portion 1222 away from the outer cylinder body 121 and is protruded outward along the circumference of the first ring portion 1222.

[0059] It should be noted that the first ring portion 1222 is connected to one end of the outer cylinder 121 close to the signal receiving member 30, and the first ring portion 1222 is extended in a direction away from the outer cylinder 121. The second ring portion 1223 is bent and connected to one end of the first ring portion 1222 away from the outer cylinder 121, and the second ring portion 1223 is formed to protrude outward along the circumference of the first ring portion 1222, and the second ring portion 1223 can be used to abut against the signal receiving member 30.

[0060] By adopting the above solution, the shielding ring 122 can contact and press the signal receiving element 30 through the second ring portion 1223 formed by protruding outward along the circumference of the first ring portion 1222, so as to increase the contact area with the signal receiving element 30 and improve the contact tightness with the signal receiving element 30. Based on this, the connection stability and connection reliability of the shielding ring 122 and the signal receiving element 30 can be improved, and the shielding ring 122 can be more effectively blocked by external signal interference and prevent internal signal leakage based on the first ring portion 1222 and the second ring portion 1223, and the signal shielding effect of the shielding ring 122 between the outer conductor 12 and the signal receiving element 30 can be optimized. Furthermore, the second ring portion 1223 is bent relative to the first ring portion 1222, so that the second ring portion 1223 can be more easily elastically deformed relative to the first ring portion 1222. Based on this, the deformation resistance of the shielding ring 122 can be reduced, and the elastic deformation ability of the shielding ring 122 under force conditions can be optimized, which can facilitate the shielding ring 122 to quickly and reliably elastically press the signal receiving component 30, thereby improving the assembly convenience and efficiency between the connector 10 and the signal receiving component 30, and optimizing the signal shielding effect between the outer conductor 12 of the connector 10 and the signal receiving component 30 based on the shielding ring 122.

[0061] Of course, in other embodiments, the shielding ring 122 may only include the first ring portion 1222 .

[0062] See also Figure 2 , Figure 3 , Figure 4 In some embodiments of the present application, one end of the inner conductor 11 close to the signal receiving element 30 is spaced apart from the signal receiving element 30 and capacitively coupled.

[0063] By adopting the above scheme, the inner conductor 11 can be spaced from the signal receiving element 30 by setting the end thereof close to the signal receiving element 30 so that the inner conductor 11 and the signal receiving element 30 can use air as a medium and form an effective capacitor, thereby facilitating stable and reliable capacitive coupling between the inner conductor 11 and the signal receiving element 30, facilitating the transmission of signals and energy from the inner conductor 11 to the signal receiving element 30 when the inner conductor 11 and the signal receiving element 30 are not in direct contact, thereby improving the flexibility of signal transmission and reducing signal loss and interference. In addition, since the inner conductor 11 and the signal receiving element 30 are spaced from each other and do not require direct physical connection and have no connection points, the inner conductor 11 and the signal receiving element 30 do not require high installation accuracy and alignment accuracy and can accommodate a certain installation tolerance, thereby improving the assembly convenience, assembly yield and assembly efficiency between the connector 10 and the signal receiving element 30. Furthermore, since the inner conductor 11 and the signal receiving element 30 are spaced apart and not in direct contact, the structure of the inner conductor 11 can be simplified in design, and there is no need to complicate the structure of the inner conductor 11 itself as in the case of inductive coupling (for example, when the inner conductor 11 and the signal receiving element 30 are inductively coupled hereinafter, the inner conductor 11 includes a base 113, an elastic member 114 and a connecting pin 115, and the base 113 is provided with a groove 1131. The structure of the inner conductor 11 is complex and has too many parts. The multiple parts of the inner conductor 11 also need to be assembled, and the assembly process is too many and cumbersome). This can effectively simplify the structure of the inner conductor 11, facilitate the processing and manufacturing of the inner conductor 11, effectively reduce the number of parts, simplify the assembly process, and improve assembly efficiency.

[0064] See also Figure 2 , Figure 3 , Figure 4 In some embodiments of the present application, the inner conductor 11 includes a main body 111 and a coupling portion 112 connected to an end of the main body 111 close to the signal receiving element 30 ; along the axial direction of the inner conductor 11 , the projection of the coupling portion 112 covers the projection of the main body 111 .

[0065] It should be noted that one end of the main body 111 is coupled to the signal transmitter 20 (can be an inductive coupling connection or a capacitive coupling connection) to realize the introduction of signals and energy from the signal transmitter 20; the other end of the main body 111 is connected to and supports the coupling part 112. The main body 111 and the coupling part 112 can be connected as one piece or separately, and the separate connection method can be, but is not limited to, welding, fusion, and the like.

[0066] Along the circumference of the inner conductor 11, the coupling portion 112 protrudes from the main body 111. Along the axial direction of the inner conductor 11, the projection of the coupling portion 112 covers the projection of the main body 111, that is, the projection of the main body 111 falls within the projection of the coupling portion 112. The projection shape of the coupling portion 112 and the projection shape of the main body 111 may be the same or different. For example, the shape of the coupling portion 112 may be circular, polygonal, and the like. The projection area of ​​the coupling portion 112 is larger than the projection area of ​​the main body 111, and can be used for relative coupling with the signal receiving component 30 (signal receiving disk 31), and relatively increase the coupling area.

[0067] By adopting the above scheme, the inner conductor 11 can be coupled and connected with the signal sending element 20 through the main body 111, and connected and supported by the coupling part 112; it can also be relatively coupled with the signal receiving element 30 (signal receiving disk 31) through the coupling part 112 connected to one end of the main body 111 close to the signal receiving element 30 and having a larger projected area. Based on this, the coupling area between the inner conductor 11 and the signal receiving element 30 can be increased, so that the coupling strength of the capacitive coupling between the inner conductor 11 and the signal receiving element 30 can be improved, and the signal transmission reliability between the connector 10 and the signal receiving element 30 can be improved. Among them, the coupling strength between the coupling part 112 and the signal receiving element 30 can be controlled by controlling the relative coupling area and / or relative coupling distance between the coupling part 112 and the signal receiving element 30 (signal receiving disk 31).

[0068] Of course, in other embodiments, the inner conductor 11 may include only the main body portion 111 , while omitting the coupling portion 112 .

[0069] Of course, in other embodiments, the inner conductor 11 and the signal receiving component 30 can be connected by a hole and a shaft, and by setting the inner wall of the hole and the outer wall of the shaft apart, the inner wall of the hole and the outer wall of the shaft can be connected with air (or an insulating sleeve) as a medium, so that an effective capacitor can be formed, thereby realizing capacitive coupling.

[0070] See also Figure 5 , Figure 6 In some embodiments of the present application, one end of the inner conductor 11 close to the signal receiving element 30 elastically abuts against the signal receiving element 30 and is inductively coupled.

[0071] By adopting the above scheme, the end of the inner conductor 11 close to the signal receiving element 30 can be elastically abutted against the signal receiving element 30 to promote good contact between the inner conductor 11 and the signal receiving element 30, thereby facilitating stable and reliable inductive coupling between the inner conductor 11 and the signal receiving element 30, facilitating the transmission of signals and energy from the inner conductor 11 to the signal receiving element 30, and reducing signal losses caused by poor contact.

[0072] See also Figure 5 , Figure 6 In some embodiments of the present application, the inner conductor 11 includes a base 113, an elastic member 114 and a connecting needle 115, one end of the base 113 is connected to the signal sending member 20, and the other end of the base 113 is provided with a groove 1131, the elastic member 114 is located in the groove 1131, and is elastically connected between the base 113 and the connecting needle 115, one end of the connecting needle 115 extends into the groove 1131 and contacts the inner wall of the groove 1131, and the other end of the connecting needle 115 elastically abuts against the signal receiving member 30.

[0073] It should be noted that one end of the base 113 is coupled to the signal transmitter 20 (may be an inductive coupling connection or a capacitive coupling connection) to achieve the transmission of signals and energy from the signal transmitter 20 to the base 113. A groove 1131 is provided at one end of the base 113 away from the signal transmitter 20, and one end of the connecting needle 115 extends into the groove 1131, and the outer wall of the connecting needle 115 contacts the inner wall of the groove 1131 to achieve the transmission of signals and energy from the base 113 to the connecting needle 115.

[0074] The connecting needle 115 can move axially relative to the groove 1131. The elastic member 114 is accommodated in the groove 1131, one end of the elastic member 114 is connected to the groove bottom of the groove 1131, and the other end of the elastic member 114 is connected to the connecting needle 115, so that the elastic member 114 is elastically connected between the base 113 and the connecting needle 115. When the connecting needle 115 moves in the direction close to the groove bottom of the groove 1131, the elastic member 114 can be compressed and deformed by force, and generate elastic force that reacts to the connecting needle 115. Based on the elastic force of the elastic member 114, the end of the connecting needle 115 away from the elastic member 114 can elastically abut against the signal receiving member 30, so as to realize the transmission of signals and energy from the connecting needle 115 to the signal receiving member 30. Among them, the elastic member 114 can be but not limited to a spring.

[0075] By adopting the above scheme, the inner conductor 11 can provide elastic displacement space and elastic force for the connecting needle 115 through the elastic member 114 elastically connected between the base 113 and the connecting needle 115, so that the connecting needle 115 can reliably elastically abut the signal receiving member 30, thereby facilitating stable and reliable inductive coupling between the inner conductor 11 and the signal receiving member 30, facilitating the transmission of signals and energy from the signal sending member 20 to the signal receiving member 30 via the base 113 and the connecting needle 115, and reducing signal loss. In addition, based on the structural design of the base 113, the elastic member 114 and the connecting needle 115, the structure of the inner conductor 11 can be simplified and optimized, which helps to conveniently, quickly and reliably assemble and form the inner conductor 11, and improves the assembly convenience and structural reliability of the inner conductor 11.

[0076] Of course, in other embodiments, the elastic member 114 may be omitted, and at least one of the base 113 and the connecting needle 115 may be elastic so that the end of the inner conductor 11 close to the signal receiving member 30 can elastically abut against the signal receiving member 30 .

[0077] See also Figure 1 Some embodiments of the present application provide an active antenna unit, including a signal sending component 20, a signal receiving component 30, and a connector 10 provided in an embodiment of the present application.

[0078] By adopting the above-mentioned scheme, the active antenna unit can realize the transmission of signals and energy from the signal sending component 20 to the signal receiving component 30 by applying the connector 10 provided in the embodiment of the present application, and optimize the signal shielding effect based on the shielding ring 122 between the outer conductor 12 of the connector 10 and the signal receiving component 30, and improve the overall assembly convenience and assembly efficiency.

[0079] See also Figure 1 , Figure 3 , Figure 4 In some embodiments of the present application, a signal receiving disk 31 is provided on the side of the signal receiving member 30 facing the connector 10, the signal receiving disk 31 is arranged corresponding to the connector 10, the shielding ring 122 is elastically pressed against the signal receiving disk 31, and the inner conductor 11 is coupled and connected to the signal receiving disk 31.

[0080] It should be noted that a signal receiving disk 31 is provided on the side of the signal receiving member 30 facing the connector 10. The signal receiving disk 31 is provided corresponding to the connector 10 and can be used to receive signals and energy from the connector 10. The signal receiving disk 31 can be, but is not limited to, a metal disk such as a soldering pad. The shape of the signal receiving disk 31 can be set as required, for example, it can be a circular disk, a rectangular disk, a polygonal disk, etc.

[0081] By adopting the above solution, the signal receiving component 30 can be coupled and connected with the inner conductor 11 through the signal receiving disk 31 as a special signal receiving interface, and effectively receive the signal and energy transmitted by the inner conductor 11, thereby improving the signal transmission integrity and signal transmission efficiency. The signal receiving component 30 can also use the signal receiving disk 31 as a special signal shielding contact surface for the shielding ring 122 to elastically press against, and cooperate with the shielding ring 122 to achieve signal shielding, thereby preventing the signal from leaking between the outer conductor 12 of the connector 10 and the signal receiving component 30, and optimizing the signal shielding effect between the outer conductor 12 of the connector 10 and the signal receiving component 30 based on the shielding ring 122 and the signal receiving disk 31.

[0082] See also Figure 1 , Figure 3 , Figure 4In some embodiments of the present application, the signal receiving disk 31 includes a signal coupling portion 311 and a signal shielding portion 312 surrounding the outer periphery of the signal coupling portion 311 , the shielding ring 122 elastically presses against the signal shielding portion 312 , and the inner conductor 11 is coupled and connected to the signal coupling portion 311 .

[0083] It should be noted that the signal coupling part 311 is arranged corresponding to the inner conductor 11, and can be coupled to the inner conductor 11. The shape and size of the signal coupling part 311 can be set as required according to coupling requirements.

[0084] The signal shielding portion 312 may be arranged in a ring shape, and the signal shielding portion 312 surrounds the outer periphery of the signal coupling portion 311, and the inner ring edge of the signal shielding portion 312 and the outer periphery of the signal coupling portion 311 may be arranged at intervals. The surrounding shape of the signal shielding portion 312 may be substantially the same as the surrounding shape of the shielding ring 122, and the signal shielding portion 312 and the shielding ring 122 are arranged correspondingly, so that the shielding ring 122 can be elastically pressed.

[0085] By adopting the above scheme, the signal receiving disk 31 can be coupled with the inner conductor 11 via the signal coupling part 311 as the main channel for signal transmission, and effectively receive the signal and energy transmitted by the inner conductor 11, thereby improving the signal transmission integrity and signal transmission efficiency, and reducing the signal loss during the transmission process. The signal receiving disk 31 can also form a circumferentially continuous and effective shielding layer through the signal shielding part 312 surrounding the outer periphery of the signal coupling part 311, so that the shielding ring 122 can be elastically pressed, and the shielding ring 122 can be used to achieve signal shielding, thereby preventing the signal from leaking between the outer conductor 12 of the connector 10 and the signal receiving part 30, and optimizing the signal shielding effect between the outer conductor 12 of the connector 10 and the signal receiving part 30 based on the shielding ring 122 and the signal shielding part 312.

[0086] This embodiment is particularly suitable for application in combination with the embodiment of "the end of the inner conductor 11 close to the signal receiving element 30 is spaced apart from the signal receiving element 30 and capacitively coupled", and is also particularly suitable for application in combination with the embodiment of "the inner conductor 11 includes a main body 111, and a coupling portion 112 connected to the end of the main body 111 close to the signal receiving element 30; along the axial direction of the inner conductor 11, the projection of the coupling portion 112 covers the projection of the main body 111". Based on the separate design of the signal coupling portion 311 and the signal shielding portion 312, when the end of the inner conductor 11 close to the signal receiving element 30 is capacitively coupled to the signal receiving element 30, the shape and size of the signal coupling portion 311 can be easily adjusted as needed to adjust the relative coupling area between the signal coupling portion 311 and the inner conductor 11, so that the coupling strength between the inner conductor 11 and the signal receiving element 30 can be adjusted quickly and accurately.

[0087] See also Figure 1 , Figure 5 , Figure 6 In some embodiments of the present application, along the axial direction of the connector 10 , the projection of the signal receiving disk 31 covers the projection of the connector 10 .

[0088] It should be noted that the signal receiving disk 31 is an integral metal disk without separate parts. Along the axial direction of the connector 10 , the projection of the signal receiving disk 31 covers the projection of the connector 10 , that is, the projection of the connector 10 falls within the projection of the signal receiving disk 31 .

[0089] By adopting the above solution, the signal receiving disk 31 with a larger projection area can be coupled with the inner conductor 11 and can also be elastically pressed by the shielding ring 122. Based on this, the structure of the signal receiving disk 31 and the signal receiving member 30 can be simplified, the connector 10 and the signal receiving disk 31 can be quickly aligned and matched, and the assembly convenience and efficiency between the connector 10 and the signal receiving member 30 can be improved.
