DETAILED DESCRIPTION

[0043] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0044] See also Figure 1 or Fig.13 , Figure 1 and Fig.13 The schematic diagrams of the structures of the radio frequency devices in the two embodiments of the present application are respectively shown. The radio frequency device provided in one embodiment of the present application includes a radio frequency connector 10 and a cavity device 20. The radio frequency connector 10 is used in conjunction with the cavity device 20. The specific structure of the radio frequency connector 10 can be referred to in Figures 8 to 10 The specific structure of the cavity device 20 can be found in Figures 4 to 6 .

[0045] See also Figures 8 to 10 Specifically, the RF connector 10 includes a docking assembly 11 and a transmission line 12. The docking assembly 11 includes a conductive housing 111, an electrical connector 112 and a first supporting dielectric member 113.

[0046] Please refer to Figure 1 , Figure 3 , Fig. 9 and Fig.10 , the conductive shell 111 is used to be connected to the outer wall of the cavity device 20 and electrically connected to the cavity device 20. The electrical connector 112 is inserted into the conductive shell 111, and the electrical connector 112 is provided with a first end 1121 and a second end 1122 opposite to each other. The first end 1121 extends out of the conductive shell 111 and extends into the interior of the cavity device 20 through the joint hole 211 of the cavity device 20. The first end 1121 is used to achieve electrical connection with the first feeder 23 of the cavity device 20 by plugging and combining. The first supporting dielectric member 113 is connected between the electrical connector 112 and the conductive shell 111, so that the electrical connector 112 and the conductive shell 111 are insulated and isolated from each other. The transmission line 12 is connected to the docking assembly 11, and the transmission line 12 includes an inner conductor 121, an outer conductor 122 and a first insulating layer 123 arranged coaxially. The first insulating layer 123 is arranged between the inner conductor 121 and the outer conductor 122. The inner conductor 121 is electrically connected to the second end 1122 , and the outer conductor 122 is electrically connected to the conductive shell 111 .

[0047] In the above-mentioned radio frequency device, on the one hand, the conductive shell 111 of the docking assembly 11 is electrically connected to the outer conductor 122 of the transmission line 12 and grounded, and is directly mounted on the outer wall of the cavity device 20 and electrically connected to the cavity device 20 to achieve grounding; on the other hand, the second end 1122 of the electrical connector 112 is electrically connected to the inner conductor 121 of the transmission line 12, the first end 1121 extends out of the conductive shell 111 and extends into the interior of the cavity device 20 through the connector hole 211 of the cavity device 20, and the first end 1121 is electrically connected to the first feeding member 23 of the cavity device 20 by means of plug-in combination. It can be seen that there is no need to separately set a radio frequency connector on the outside of the cavity device 20, nor is there a need to set a screw sleeve on the radio frequency connector 10. The conductive shell 111 is electrically connected to the outer wall of the cavity device 20, and the first end 1121 is extended into the cavity device 20 and electrically connected to the first feeding member 23 to achieve a combined connection between the transmission line 12 and the cavity device 20. This not only avoids the first end 1121 being located outside the cavity device 20 and occupying space, but also saves the space occupied by the radio frequency connector outside the cavity device 20. The overall volume is reduced, and at the same time, the product weight can be reduced, thereby achieving the purpose of reducing costs.

[0048] See also Fig.13 Since the volume size of the RF device in this embodiment is reduced, the occupied space size is reduced, thereby meeting the high requirements on the external size and cost when at least two cavity devices 20 are cascaded together.

[0049] The transmission line 12 includes, but is not limited to, a coaxial cable.

[0050] See also Fig. 9 and Fig.10 Optionally, the transmission line 12 further includes a second insulating layer 124 , and the second insulating layer 124 is disposed outside the outer conductor 122 .

[0051] The first feeder 23 and the first end 1121 can be electrically connected by abutting or by coupling feeding, which is not limited here and can be flexibly adjusted and set according to actual needs. In this embodiment, the first feeder 23 and the first end 1121 are electrically connected by abutting.

[0052] The first feeder 23 and the first end 1121 are combined and connected by plugging a male head and a female head into each other. When the first feeder 23 is provided with a male head, the first end 1121 is provided with a female head corresponding to the male head; conversely, when the first feeder 23 is provided with a female head, the first end 1121 is provided with a male head corresponding to the female head.

[0053] For example, the first end 1121 is provided with a female connector, specifically, an insertion hole 11211 extending along the axial direction thereof is formed, and the first feeder 23 is correspondingly provided with a male connector, specifically, for example, plugged into and matched with the insertion hole 11211. During assembly, the first end 1121 is plugged and combined with the end of the first feeder 23 through the insertion hole 11211, so that the first end 1121 and the first feeder 23 can be quickly assembled and docked together, and the disassembly operation is also convenient.

[0054] In some embodiments, the first feeding element 23 includes but is not limited to a feeding rod, a feeding bar or a feeding plate, etc., which can be flexibly adjusted and set according to actual needs and is not limited here, as long as the signal transmission between the transmission line 12 and the first resonant column 22 can be achieved.

[0055] In this embodiment, in order to facilitate the combination with the first end 1121 in a plug-in manner, the first feeder 23 is, for example, configured as a feed rod. The cross-section of the feed rod along its central axis includes, but is not limited to, regular shapes such as a circle, an ellipse or a polygon and other irregular shapes. Specifically, the axial cross-sectional profile of the feed rod is adapted to the axial profile shape of the insertion hole 11211. As a specific example, the axial cross-sectional profile of the feed rod and the axial profile shape of the insertion hole 11211 are both specifically circular. In addition, the feed rod is, for example, interference fit with the insertion hole 11211.

[0056] See also Figure 3 , Figure 8 and Fig. 9On the basis of the above-mentioned embodiment, the first end 1121 includes a plurality of clamping parts 11212 arranged around its central axis, and the plurality of clamping parts 11212 enclose an insertion hole 11211. When the first end 1121 is inserted into the first feeder 23, the first feeder 23 can push outward each clamping part 11212 during the process of entering the insertion hole 11211. After each clamping part 11212 is pushed open, the first feeder 23 is clamped and fixed by elastic force. In this way, the first end 1121 and the first feeder 23 can be firmly assembled together, and the intermodulation index is stable and reliable.

[0057] Optionally, the end of the feeding rod that is plugged into the insertion hole 11211 is set as a tapered portion 231. In this way, the end of the feeding rod can be easily inserted and assembled into the insertion hole 11211, elastically abutting against the inner wall of the insertion hole 11211, and the assembled structure is stable and the intermodulation index is reliable.

[0058] The connection method of the conductive shell 111 on the outer wall of the cavity device 20 includes but is not limited to connection through the first fastener 13, snap connection, connection through conductive adhesive, welding fixation or connection in other ways. It can be flexibly adjusted and set according to actual needs and is not limited here.

[0059] In this embodiment, the conductive shell 111 is, for example, detachably connected to the outer wall of the cavity device 20 .

[0060] See also Figures 1 to 3 In a specific embodiment, the conductive shell 111 is provided with a first mounting portion 1111, and the RF connector 10 further includes a first fastener 13. The first mounting portion 1111 is attached to the outer wall of the cavity device 20, and is connected and fixed to the cavity device 20 through the first fastener 13. In this way, the conductive shell 111 is directly attached to the outer wall of the cavity device 20 through its first mounting portion 1111, and there is no need to add an RF connector between the conductive shell 111 and the outer wall of the cavity device 20, thereby reducing the overall volume size. In addition, under the fixing action of the first fastener 13, the conductive shell 111 can be stably mounted on the outer wall of the cavity device 20.

[0061] Optionally, the first fastener 13 includes but is not limited to screws, pins or rivets, etc., as long as the first mounting portion 1111 can be locked and fixed to the outer wall of the cavity device 20.

[0062] Optionally, the number of the first fasteners 13 is not limited to one, and can be, for example, multiple. The multiple first fasteners 13 are arranged on the first mounting portion 1111 at intervals.

[0063] See also Figure 3 , Fig. 9 and Fig.10In one embodiment, the RF connector 10 further includes a first sealing ring 14. The first sealing ring 14 is connected between the conductive shell 111 and the outer wall of the cavity device 20. The first mounting portion 1111 is arranged around the circumference of the electrical connector 112, and the first mounting portion 1111 faces the outer wall of the cavity device 20 and abuts against the outer wall of the cavity device 20 through the first sealing ring 14. In this way, the first sealing ring 14 can improve the sealing performance at the connection portion between the RF connector 10 and the cavity device 20, thereby having better waterproof performance.

[0064] On the basis of the above-mentioned embodiment, a mounting groove 1112 is formed on one side of the first mounting portion 1111 facing the outer wall of the cavity device 20 , and the first sealing ring 14 is installed inside the mounting groove 1112 .

[0065] In some embodiments, the material of the first supporting medium member 113 includes, but is not limited to, plastic or rubber, etc., and can be flexibly adjusted and set according to actual needs, which is not limited here.

[0066] In some embodiments, the first supporting dielectric member 113 is disposed around the circumference of the electrical connector 112. Optionally, the first supporting dielectric member 113 is a dielectric sleeve. In this way, the first supporting dielectric member 113 can effectively insulate and isolate the electrical connector 112 from the conductive housing 111, and can prevent the two from contacting each other and causing a short circuit. In addition, the first supporting dielectric member 113 is limitedly matched with the inner wall of the conductive housing 111 and / or the outer wall of the electrical connector 112 along the direction of its central axis. In this way, the first supporting dielectric member 113 is stably installed inside the conductive housing 111.

[0067] See also Figure 3 and Fig. 9 In one embodiment, the inner wall of the conductive housing 111 is provided with a first step 1113, and the first step 1113 abuts against one end of the first supporting dielectric member 113 along the central axis direction. And / or, the outer wall of the electrical connector 112 is provided with a second step 1123, and the second step 1123 is located outside the conductive housing 111 and abuts against the other end of the first supporting dielectric member 113 along the central axis direction. In this way, the first step 1113 and the second step 1123 abut against the opposite ends of the first supporting dielectric member 113, respectively, thereby effectively limiting the movement of the first supporting dielectric member 113 along the central axis direction thereof, and the first supporting dielectric member 113 is stably mounted on the conductive housing 111.

[0068] See also Fig. 9 and Fig.10In some embodiments, a resistance portion 1124 is provided on the outer wall of the electrical connector 112. The resistance portion 1124 includes but is not limited to knurling, anti-skid patterns or anti-skid bumps, etc. The resistance portion 1124 is in close contact with the first supporting dielectric member 113, thereby effectively preventing the first supporting dielectric member 113 from moving along the central axis direction, and having high stability.

[0069] In one embodiment, one end of the first supporting dielectric member 113 is used to extend into the connector hole 211 of the cavity device 20 and to have an interference fit with the connector hole 211; the first supporting dielectric member 113 also has an interference fit with the inner wall of the conductive shell 111. In this way, the first supporting dielectric member 113 can not only stably support the electrical connector 112, thereby ensuring a stable connection between the electrical connector 112 and the first feeding member 23, but also improve the sealing of the joint between the RF connector 10 and the cavity device 20, thereby having better waterproof performance.

[0070] It should be noted that the number of docking components 11 of the RF connector 10 includes but is not limited to one, two, three or any other number, which can be flexibly adjusted and set according to actual needs, and is not limited here. In this embodiment, the example of two docking components 11 will be used for introduction, but it is not limited to this, and the number of docking components 11 can also be increased or decreased according to actual needs. When there are two docking components 11, the two docking components 11 are respectively connected to the opposite ends of the transmission line 12. In this way, the two docking components 11 can be connected to the two cavity devices 20 respectively, thereby realizing the connection of the two cavity devices 20.

[0071] See also Fig.11 and Fig.12 The combination of the transmission line 12 and the docking assembly 11 can be set as a straight end or an elbow. When the transmission line 12 and the docking assembly 11 are set as a straight end, the extension direction of the inner conductor 121 of the transmission line 12 is the same as the extension direction of the electrical connector 112; when the transmission line 12 and the docking assembly 11 are set as an elbow, the extension direction of the inner conductor 121 of the transmission line 12 and the extension direction of the electrical connector 112 are set at an angle, for example, they are set perpendicular to each other.

[0072] See also Fig.12 , the combination of the two opposite ends of the transmission line 12 and the two docking components 11 is, for example, an elbow; see Fig.11 The combination form of one end of the transmission line 12 and one docking component 11 is, for example, an elbow, and the combination form of the other end of the transmission line 12 and another docking component 11 is a straight head.

[0073] See also Fig. 9 and Fig.10In one embodiment, the conductive housing 111 includes a main conductive sleeve 1114 and a guide conductive sleeve 1115. One end of the guide conductive sleeve 1115 is connected to an end of the main conductive sleeve 1114 away from the cavity device 20, and the axial direction of the guide conductive sleeve 1115 is set at an angle to the axial direction of the main conductive sleeve 1114. One end of the main conductive sleeve 1114 is connected to the outer wall of the device cavity, and the other end of the main conductive sleeve 1114 is provided with an operation port 1116 and a cover 1117. The cover 1117 is openably arranged at the operation port 1116; the electrical connector 112 is inserted into the main conductive sleeve, the transmission line 12 is inserted into the guide conductive sleeve 1115, and the inner conductor 121 extends into the main conductive sleeve 1114 and is welded to the electrical connector 112. In this way, on the one hand, through the operating port 1116, tools can be easily entered into the conductive shell 111 to connect and fix the inner conductor 121 and the electrical connector 112 by welding; on the other hand, after the inner conductor 121 is connected to the electrical connector 112, the cover 1117 is covered on the operating port 1116 to play a waterproof role; in addition, the extension direction of the transmission line 12 is set at an angle to the extension direction of the electrical connector 112, which facilitates the connection of different cavity devices 20, makes the wiring reasonable, and reduces the occupied space.

The first supporting dielectric member 113 is disposed at one end of the main conductive sleeve 1114 close to the cavity device 20.

[0076] Specifically, the outer conductor 122 is connected and fixed to the guide electric shaft sleeve by welding, for example. In this way, the outer conductor 122 is electrically connected to the guide electric shaft sleeve 1115, the guide electric shaft sleeve 1115 is electrically connected to the main conductive shaft sleeve 1114, and the main conductive shaft sleeve 1114 is electrically connected to the cavity device 20, so that the outer conductor 122, the guide electric shaft sleeve 1115, the main conductive shaft sleeve 1114 and the cavity device 20 are grounded together.

[0077] See also Fig. 9 and Fig.10In one embodiment, the RF connector 10 further includes an insulating heat shrink tube 16. The insulating heat shrink tube 16 is sleeved on the outside of the guiding conductor sleeve 1115 and also sleeved on the outside of the transmission line 12. In this way, the insulating heat shrink tube 16 can increase the connection stability between the transmission line 12 and the guiding conductor sleeve 1115, and can effectively prevent the transmission line 12 from detaching from the guiding conductor sleeve 1115, thereby ensuring the electrical connection performance between the outer conductor 122 and the guiding conductor sleeve 1115.

[0078] Of course, as some optional solutions, the inner conductor 121 is not limited to being connected to the electrical connector 112 by welding, but can also be set as an integrated structure with the electrical connector 112.

[0079] On the basis of the above-mentioned embodiment, the RF connector 10 further includes a third sealing ring 17. The third sealing ring 17 is sleeved on the outside of the guiding conductive sleeve 1115 and is located inside the insulating heat shrink tube 16. In this way, the third sealing ring 17 plays a sealing role, effectively preventing water from entering the inside of the conductive housing 111 through the gap between the guiding conductive sleeve 1115 and the transmission line 12, thereby ensuring electrical performance.

[0080] The cavity device 20 includes but is not limited to a filter, a combiner or a duplexer.

[0081] See also Figures 4 to 6 For example, the cavity device 20 includes: a resonant cavity 21 , a first resonant column 22 and a first feeding element 23 .

[0082] See also Figure 3 and Figure 6 The resonant cavity 21 is provided with a joint hole 211 , and the joint hole 211 passes through the side wall of the resonant cavity 21 , and the side wall of the resonant cavity 21 is used to be connected to the conductive shell 111 .

[0083] The first resonant column 22 is disposed inside the resonant cavity 21 , and the first resonant column 22 is connected to the bottom wall of the resonant cavity 21 .

[0084] The first feeder 23 is disposed inside the resonant cavity 21 , one end of the first feeder 23 is electrically connected to the first resonant column 22 , and the other end of the first feeder 23 is inserted into the connector hole 211 and is used to achieve electrical connection with the first end 1121 by plugging and combining.

[0085] In some embodiments, the first feeder 23 and the first resonant column 22 are electrically connected, for example, by coupling feeding, that is, there is no physical connection between the first feeder 23 and the first resonant column 22, but a gap is provided, and an insulating medium can be provided in the gap to achieve insulation isolation and fixation of the two conductive components, or no component is required, that is, insulation isolation is achieved through air. Due to the gap between the two conductive components, energy can be coupled and transmitted between the two conductive components. Of course, as some optional solutions, the first feeder 23 and the first resonant column 22 can also be directly electrically connected, for example, by welding, or by using metal screws or other locking parts to connect and fix.

[0086] In this embodiment, the first feeding element 23 and the first resonant column 22 are specifically implemented by coupling feeding, but the present invention is not limited thereto.

[0088] In some embodiments, the materials of the second supporting medium member 24 and the third supporting medium member 25 are set according to actual needs, similar to the material of the first supporting medium member 113, and can be plastic or rubber.

A flange is provided at one end of the second supporting dielectric member 24 close to the first feeding member 23, and the flange is located outside the coupling hole 221 and abuts against the first resonant column 22. The flange also abuts against the first feeding member 23 along its axial direction. In this way, the second supporting dielectric member 24 can stably support the first feeding member 23 and prevent the first feeding member 23 from moving along its axial direction.

[0090] Optionally, the third supporting dielectric member 25 is, for example, a dielectric sleeve, and the third supporting dielectric member 25 is, for example, snap-fitted with the joint hole 211 along its axial direction.

[0091] See also Figure 3 , Figure 6 and Figure 7On the basis of the above-mentioned embodiment, a limiting step 2111 and a barb structure 2112 are provided on the inner wall of the joint hole 211. The limiting step 2111 abuts and cooperates with the third supporting dielectric member 25 along its axial direction to prevent the third supporting dielectric member 25 from moving in a direction close to the first resonant column 22; the barb structure 2112 abuts and cooperates with the third supporting dielectric member 25 along its axial direction to prevent the third supporting dielectric member 25 from moving in a direction away from the first resonant column 22. In this way, the third supporting dielectric member 25 can be stably arranged inside the joint hole 211, effectively preventing the third supporting dielectric member 25 from moving along its axial direction, thereby playing a stable supporting role for the first feeding member 23.

[0092] As some optional solutions, the first feeding element 23 is not limited to being coupled and fed with the first resonant column 22 through the coupling hole 221 , and can also be coupled and fed with the first resonant column 22 through a resonant disk.

[0093] In one embodiment, the cavity device 20 further includes a second resonant column 26 and a second feeder 27. The second resonant column 26 is disposed inside the resonant cavity 21, the second resonant column 26 is connected to the bottom wall of the resonant cavity 21, the second resonant column 26 is electrically connected to one end of the second feeder 27, and the other end of the second feeder 27 is electrically connected to the first feeder 23.

[0094] The specific electrical connection mode between the second feeder 27 and the second resonant column 26 can be either coupled feeding or direct electrical connection. Similarly, the specific electrical connection mode between the second feeder 27 and the first feeder 23 can be either coupled feeding or direct electrical connection, which is not limited here.

[0095] The first resonant column 22 and the second resonant column 26 may be connected to the resonant cavity 21 in an integral manner or may be connected to the resonant cavity 21 in a detachable manner, which is not limited herein.

The spare connector 30 is configured as a RF connector, and the spare connector 30 is used to be detachably mounted on the outer wall of the cavity device 20.

In this way, the RF device can not only be cascaded through the RF connector 10, but also the RF connector 10 can be removed, and the device connector 30 and the adapter 40 can be installed on the cavity device 20. The spare connector 30 can be connected to the computer host through, for example, a cable, so as to facilitate the application of multiple scenarios.

[0098] The spare connector 30 includes a second mounting portion 32, and the RF device also includes a second fastener 33. The second mounting portion 32 is attached to the outer wall of the cavity device 20, and is connected and fixed to the cavity device 20 through the second fastener 33. In this way, the spare connector 30 is attached to the outer wall of the cavity device 20 by its second mounting portion 32 to achieve grounding.
