[0001] The present application belongs to the field of connector technology, and in particular relates to a line-end radio frequency connector and a board-end radio frequency connector. Background Art

[0002] With the widespread application of communication systems in high-vibration equipment such as automobiles and drones, RF connectors used in communications are often in high-vibration application scenarios. Figure 1 As shown, currently common RF connectors feature a socket 11' and slot 12' on the female pin 1' (board-side inner conductor) to hold the male pin 2' (line-end inner conductor). The female pin 1' (board-side inner conductor) is inserted into the socket 11' of the male pin 2' (line-end inner conductor), and the slot on the socket 11' secures the male pin 2' (line-end inner conductor). If the nut on the outside of the RF connector loosens and is exposed to high vibration, it can easily break the slot on the female pin 1' (board-side inner conductor), leading to communication interruption and device failure. Utility Model Content

[0003] The purpose of this application is to provide a line-end RF connector and a board-end RF connector to address the deficiencies of the prior art.

[0004] To achieve the above objectives, this application provides the following technical solutions:

[0005] A line-end RF connector is used to cooperate with a board-end RF connector, the line-end RF connector comprising: an outer conductor; a connecting shell, sleeved on the outside of the outer conductor; an insulator, disposed in the outer conductor; an inner conductor, disposed in the insulator, the inner conductor comprising a fixed portion, a movable portion and conductive silicone, the fixed portion being fixed in the insulator, one end of the fixed portion being provided with a mounting hole extending axially, the conductive silicone being disposed at one end of the mounting hole, one end of the movable portion being slidably disposed in the mounting hole and abutting against the conductive silicone, and the other end of the movable portion being exposed outside the fixed portion.

[0006] In some embodiments, the mounting hole is a blind hole extending backward from the front end of the fixed portion, one end of the conductive silicone abuts the bottom of the mounting hole, and the other end of the conductive silicone abuts the rear end of the movable portion.

[0007] In some embodiments, the conductive silicone is a cylinder having the same diameter as the mounting hole, and the outer wall of the conductive silicone is in contact with the inner wall of the mounting hole.

[0008] In some embodiments, the front end of the insulator is provided with a stop boss extending toward the inner conductor, and the rear end of the movable part is provided with a step portion, and the front side of the step portion abuts against the rear side of the stop boss to axially limit the movable part.

[0009] In some embodiments, a rear end of the connecting shell is connected to the outer conductor, and a front end of the connecting shell and a front end of the outer conductor form a gap in a radial direction.

[0010] In some embodiments, the connecting shell is a nut structure, the connecting shell can rotate around the outer conductor, and an inner wall of the front end of the connecting shell is provided with an internal thread.

[0011] In some embodiments, the line-end RF connector further comprises:

[0012] The housing positioning block is provided with a fixing groove, in which the connecting housing is placed. The fixing groove can prevent the connecting housing from rotating during use.

[0013] In some embodiments, the front end of the connecting shell is provided with a plurality of slits spaced apart along the circumference of the connecting shell, and the slits enable the front end of the connecting shell to be expanded or contracted;

[0014] The line-end RF connector further includes:

[0015] A sliding sleeve, slidably mounted on the outer conductor and capable of sliding forward to a position where the connecting housing is tightened;

[0016] A stopper, provided on the outer side of the outer conductor;

[0017] The elastic member has a front end abutting against the rear end of the sliding sleeve, and a rear end abutting against the stop sheet.

[0018] In some embodiments, a protrusion is provided on the inner wall of the front end of the connecting shell, and the protrusion is used to clamp the board-end RF connector.

[0019] A board-end RF connector is used to cooperate with the line-end RF connector. The board-end RF connector includes a board-end outer conductor, a board-end inner conductor and a board-end insulator. The board-end insulator is arranged between the board-end outer conductor and the board-end inner conductor. The front end surface of the board-end inner conductor abuts the inner conductor of the line-end RF connector. The front end surface of the board-end inner conductor is a continuous plane or a curved surface.

A mounting hole is provided on the fixed portion for mounting the conductive silicone and the movable portion. One end of the movable portion is slidably disposed in the mounting hole and abuts against the conductive silicone. When the board-end RF connector is connected to the wire-end RF connector, the inner conductor of the board-end RF connector contacts the movable portion of the inner conductor of the wire-end RF connector. Since the rear end of the movable portion of the inner conductor of the wire-end RF connector is provided with conductive silicone, which is elastic, the movable portion forms elastic contact with the inner conductor of the board-end RF connector, thereby ensuring the contact effect. This eliminates the need to slot the inner conductor (female pin) of the board-end RF connector to clamp the inner conductor (male pin) of the wire end, as in the background art, thereby avoiding the possibility of the slot breaking in a high-vibration environment, leading to communication interruption. At the same time, the conductive silicone can also ensure good electrical conductivity between the movable portion and the fixed portion of the inner conductor of the wire end.

[0041] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of this application.

[0042] The embodiment of the present application provides a line-end RF connector. Figures 2 to 4As shown, the line-end RF connector 10 includes an outer conductor 110 , a connecting housing 120 , an insulator 130 and an inner conductor 140 .

[0043] The connecting shell 120 is sleeved on the outer side of the outer conductor 110, and the connecting shell 120 is used to connect to the board end RF connector 20. Figure 2 As shown, the connecting housing 120 can be a nut, such as Figure 6 As shown, during assembly, the connecting housing 120 is screwed onto the board-end outer conductor 210 of the board-end RF connector 20. Figure 9 and Figure 10 As shown, the connecting housing 120 can also be a sleeve with a clamping function, such as Figure 13 As shown, during assembly, the sleeve is clamped on the board-end RF connector 20 and then locked by the sliding sleeve 150 .

[0044] like Figure 3 As shown, the insulator 130 is disposed in the outer conductor 110 . The inner conductor 140 is disposed in the insulator 130 . The inner conductor 140 and the outer conductor 110 are coaxially disposed and separated from each other by the insulator 130 .

[0045] like Figure 3 As shown, the inner conductor 140 includes a fixed portion 141, a movable portion 142 and a conductive silicone 143. The fixed portion 141 is fixedly arranged in the insulator 130, and the conductive silicone 143 and the movable portion 142 are both arranged in the fixed portion 141. Figure 3 As shown in Figure 5, one end of the fixed portion 141 is provided with a mounting hole 1411 extending in the axial direction, and the conductive silicone 143 is provided at one end of the mounting hole 1411. One end of the movable portion 142 is slidably provided in the mounting hole 1411 and abuts against the conductive silicone 143. The other end of the movable portion 142 is exposed outside the fixed portion 141, so that the movable portion 142 can contact the docking board-end RF connector 20.

[0046] When the line-end RF connector 10 is connected to the board-end RF connector 20, refer to Figure 6The board-end inner conductor 220 of the board-end RF connector 20 contacts the movable portion 142 of the line-end inner conductor 140 of the line-end RF connector 10. The board-end inner conductor 220 squeezes the movable portion 142 of the line-end inner conductor 140 axially, and the movable portion 142 moves backward. Since the rear end of the movable portion 142 abuts against the conductive silicone 143, and the conductive silicone 143 is elastic, the movable portion 142 forms elastic contact with the board-end inner conductor 140, ensuring good contact. Unlike the prior art, there is no need to cut a groove 12' on the board-end inner conductor 1' to clamp the line-end inner conductor 2'. The absence of a groove 12' on the board-end inner conductor 1' avoids communication interruption caused by broken slots. At the same time, the conductive silicone 143 can ensure good contact between the movable portion 142 of the line-end inner conductor 140 and the fixed portion 141. The conductive silicone 143 has a large contact area with the conductor and good conductivity.

[0047] The mounting hole 1411 on the fixing portion 141 can be a regular-shaped hole or an irregular-shaped cavity, without limitation, as long as it can accommodate the conductive silicone 143 and the movable portion 142. Figure 3 As shown, mounting hole 1411 is a cylindrical blind hole extending rearward from the front end of fixed portion 141. One end of conductive silicone rubber 143 abuts the bottom of mounting hole 1411, while the other end abuts the rear end of movable portion 142. Designing mounting hole 1411 as a blind hole and abutting conductive silicone rubber 143 against the bottom of the blind hole allows conductive silicone rubber 143 to rest more securely on fixed portion 141, providing better support for movable portion 142.

[0048] Further, such as Figure 5 As shown, the conductive silicone 143 is a cylinder with the same diameter as the mounting hole 1411. When the conductive silicone 143 is installed in the mounting hole 1411, as shown in FIG. Figure 3 As shown, the outer wall of the conductive silicone 143 is in contact with the inner wall of the mounting hole 1411. As mentioned above, the rear end of the conductive silicone 143 is in contact with the bottom of the mounting hole 1411, so that the side walls and bottom of the conductive silicone 143 are in close contact with the mounting hole 1411, ensuring the conductive effect.

[0049] It is understandable that the conductive silicone 143 can also be replaced with other conductive and elastic materials.

[0050] Since the movable portion 142 of the inner conductor 140 can move in the mounting hole 1411 of the fixed portion 141, in order to prevent the movable portion 142 from falling out, as shown in FIG. Figure 3 As shown, the front end of the insulator 130 is provided with a stop boss 131, and the stop boss 131 extends radially toward the inner conductor 140. Correspondingly, the rear end of the movable portion 142 is provided with a step portion 1421 for cooperating with the stop boss 131. Figure 3 As shown, the front side of the step portion 1421 abuts against the rear side of the stop boss 131, thereby limiting the axial position of the movable portion 142. During assembly, the conductive silicone 143 and the movable portion 142 are sequentially installed into the mounting hole 1411 on the fixed portion 141. The fixed portion 141, the conductive silicone 143 and the movable portion 142 constitute the inner conductor 140 of the line-end RF connector 10. The inner conductor 140 is inserted into the insulator 130 from the back to the front until the step portion 1421 on the movable portion 142 abuts against the stop boss 131 on the insulator 130. Figure 3 As shown, the front end of the movable portion 142 is exposed from the front end of the insulator 130 to contact the board-side inner conductor 220 of the board-side RF connector 20 .

[0051] like Figure 3 As shown, the front end of the connection housing 120 has an insertion port 121, and the board-side RF connector 20 is inserted into the insertion port 121. Figure 3 As shown, the rear end of the connecting shell 120 is connected to the outer conductor 110, and the front end of the connecting shell 120 and the front end of the outer conductor 110 form a gap d in the radial direction. Figure 3 and Figure 6 The gap d is used to accommodate the board-end outer conductor 210 of the board-end RF connector 20. Figure 6 As shown, the board-end outer conductor 210 of the board-end RF connector 20 extends into the gap d between the front end of the connection shell 120 and the front end of the outer conductor 110, the outer side of the board-end outer conductor 210 is connected to the inner wall of the connection shell 120, and the inner side of the board-end outer conductor 210 is in contact with the line-end outer conductor 110, thereby achieving electrical connection.

[0052] There are many ways to connect the housing 120 and the board end outer conductor 210. In the embodiment of the present application, the following are provided: Figure 6 and Figure 13 The two methods shown in FIG. The two methods correspond to different connection housing 120 structures. First, Figure 6 The structure of the connecting housing 120. Figure 2 、 Figure 3 and Figure 6 As shown, the connecting shell 120 is a nut structure, and the connecting shell 120 can rotate around the outer conductor 110, and the inner wall of the front end of the connecting shell 120 is provided with an internal thread 122. Figure 3 As shown, a limiting ring 111 is provided on the outside of the outer conductor 110, and an annular groove 123 is provided on the inner wall of the rear end of the connecting shell 120 to cooperate with the limiting ring 111. The annular groove 123 cooperates with the limiting ring 111 to axially limit the connecting shell 120. The connecting shell 120 can rotate around the outer conductor 110, so that the connecting shell 120 will be screwed into the board-end outer conductor 210. After the connecting shell 120 is screwed into the board-end outer conductor 210 of the board-end RF connector 20, Figure 6It is understood that the plate end outer conductor 210 is provided with an outer thread 211 that matches the inner thread 122 on the connecting shell 120 .

[0053] like Figure 2 As shown, the outer contour of the connecting housing 120 is in the shape of a hexagonal nut, which is convenient for screwing with a tool such as a wrench.

[0054] In order to prevent the connection housing 120 from loosening in a vibration environment, in the embodiment of the present application, Figure 7 As shown, a housing positioning block 180 is provided. The housing positioning block 180 can be provided on the terminal to which the line-end RF connector 10 of the present application is applied. Figure 7 As shown, the housing positioning block 180 is provided with a fixing groove 181, into which the connecting housing 120 is placed. The fixing groove 181 prevents the connecting housing 120 from rotating during use. Specifically, the profile of the fixing groove 181 can be configured to match the shape of the hexagonal nut of the housing positioning block 180. Once the connecting housing 120 is engaged with the fixing groove 181, the connecting housing 120 cannot rotate and will not become loose.

[0055] In addition, in order to cushion the vibration in a vibration environment, such as Figure 3 As shown, a shock-absorbing rubber ring 112 is also provided on the outer conductor 110. Figure 6 As shown, the front end surface of the shock-absorbing rubber ring 112 abuts against the front end of the board-end outer conductor 210 of the board-end RF connector 20, and the rear end surface of the shock-absorbing rubber ring 112 abuts against the outer conductor 110 of the line-end RF connector 10, that is, the shock-absorbing rubber ring 112 is arranged between the outer conductor 110 of the line-end RF connector 10 and the end surface of the board-end outer conductor 210 of the board-end RF connector 20, thereby playing a buffering role.

[0056] like Figure 13 In the embodiment shown, the structure of the connecting shell 120 is different from the nut structure connecting shell 120 described above. In another optional embodiment, the structure of the connecting shell 120 is different from the nut structure connecting shell 120 described above. Figure 11 and Figure 13 As shown, the connecting shell 120 is sleeve-shaped, and the front end of the connecting shell 120 is provided with a plurality of slits 124 distributed along the circumference of the connecting shell 120. The slits 124 make the front end of the connecting shell 120 elastic and can be opened or contracted, so that it can be clamped into the board-end outer conductor 210 of the board-end RF connector 20.

[0057] like Figure 9 and Figure 10 As shown, the line end RF connector 10 further includes a sleeve 150, a stopper 160 and an elastic member 170. The sleeve 150 is used to lock the connection housing 120. The sleeve 150 is slidably mounted on the outer conductor 110 and can slide forward and backward along the axial direction. Figure 13As shown, the sliding sleeve 150 can slide forward to a position where the connecting housing 120 is clamped. When the connecting housing 120 is connected to the plate end outer conductor 210, as shown in FIG. Figure 12 As shown, the sliding sleeve 150 is pushed backward to the rear of the connecting housing 120. At this time, the front end of the connecting housing 120 is not restricted by the sliding sleeve 150 and can be opened freely, so that the front end of the connecting housing 120 can be stuck on the board end outer conductor 210. After the connecting housing 120 is connected to the board end outer conductor 210, as shown in FIG. Figure 13 As shown, the sliding sleeve 150 slides onto the outer portion of the connecting housing 120, locking the connecting housing 120. The front end of the connecting housing 120 is tightened and cannot be opened, thereby locking it to the board end outer conductor 210. The stopper 160 is provided on the outer side of the outer conductor 110. The front end of the elastic member 170 abuts the rear end of the sliding sleeve 150, and the rear end of the elastic member 170 abuts the stopper 160. The elastic member 170 thus presses against the sliding sleeve 150 and secures it to the connecting housing 120. The elastic member 170 can be a spring.

[0058] In order to allow the connecting housing 120 to clamp the board end outer conductor 210 more tightly, as shown in FIG. Figure 10 As shown, a protrusion 125 is provided on the inner wall of the front end of the connection housing 120, and the protrusion 125 is used to clamp the board end outer conductor 210 of the board end RF connector 20. The provision of the protrusion 125 makes the front end diameter of the connection housing 120 smaller and the clamping effect better.

[0059] The present application also discloses a board-side RF connector 20. Figure 14 As shown, the board-end RF connector 20 includes a board-end outer conductor 210, a board-end inner conductor 220, and a board-end insulator 230. The board-end insulator 230 is disposed between the board-end outer conductor 210 and the board-end inner conductor 220. Figure 6 and Figure 13 As shown, the board-side RF connector 20 can cooperate with the line-side RF connector 10 to achieve communication transmission. Figure 6 As shown, after mating, the board-end inner conductor 220 of the board-end RF connector 20 contacts the line-end inner conductor 140 of the line-end RF connector 10. As mentioned above, since the conductive silicone 143 is provided in the line-end inner conductor 140, the line-end inner conductor 140 and the board-end inner conductor 220 can achieve elastic contact, ensuring the contact effect. Therefore, in the embodiment of the present application, Figure 14 As shown, it is not necessary to provide the jack 11' and the slot 12' as described in the background art on the board-end inner conductor 220 of the board-end RF connector 20 to clamp the line-end inner conductor 140. Figure 14 As shown in the embodiment of the present application, the front end surface of the plate end inner conductor 220 is a continuous plane or curved surface without openings. Figure 6As shown, the front end surface of the board-end inner conductor 220 directly contacts the inner conductor 140 of the line-end RF connector 10 , and under the action of the conductive silicone 143 , a good contact effect is ensured without the need for a groove 12 ′.
