Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of communication, and particularly relates to a radio frequency connector. BACKGROUND

[0002] In the field of communication, a radio frequency connector is used to connect a cable to an electronic device to realize signal transmission, and is mainly used for transmitting radio frequency signals.

[0003] In the related art, a radio frequency connector generally comprises a first connector and a second connector, the first connector and the second connector are plugged and matched, the first connector is connected with an interface of an electronic device, and the second connector is connected with a cable. However, after long-time use, the connection structure of the first connector and the second connector is prone to loosening, which causes the first connector and the second connector to be easily disconnected, and affects the transmission of radio frequency signals. CONTENT OF THE UTILITY MODEL

[0004] The embodiment of the application aims to provide a radio frequency connector, which can solve the problem that the connection between the first connector and the second connector of the radio frequency connector in the related art is prone to loosening and affects signal transmission.

[0005] The embodiment of the application provides a radio frequency connector, which comprises a first connector, a second connector, a connecting piece and a locking piece, one of the first connector and the second connector is used to connect an electronic device, and the other is used to connect a cable, the first connector and the second connector are plugged and matched,

[0006] The connecting piece is connected with the first connector, one of the second connector and the connecting piece is provided with a first limiting structure, the first limiting structure is provided with a locking groove, the other is provided with a limiting groove and the locking piece, the limiting groove extends along the direction of the central axis of the radio frequency connector, the first limiting structure extends into the limiting groove, the first limiting structure and the limiting groove are limited and matched in the direction of the central axis, and the first limiting structure and the limiting groove are slidingly matched in the direction around the central axis, so that the second connector and the connecting piece can relatively rotate,

[0007] When the second connector and the connecting piece relatively rotate to a locking position, the locking groove is opposite to the locking piece, the locking piece can extend into the locking groove, so that the second connector and the connecting piece are relatively fixed.

[0008] In this embodiment, the RF connector is equipped with a connecting member, which is connected to the first connector. The connecting member and the second connector are locked together in the plugged-in state through a special structure. Specifically, one of the second connector and the connecting member is provided with a first limiting structure and a locking groove, and the other is provided with a limiting groove and a locking member. The first limiting structure extends into the limiting groove, so that the first limiting structure slides in the limiting groove along the direction around the central axis. The first limiting structure and the limiting groove are in a limiting engagement in the direction of the central axis, so as to realize the rotational engagement of the second connector and the connecting member. At the same time, it prevents the second connector and the connecting member from moving relative to each other along the central axis and separating. Furthermore, when the second connector and the connecting member rotate relative to each other to the locking position, the locking member is opposite to the locking groove, and the locking member can extend into the locking groove. The first limiting structure can no longer slide along the limiting groove. That is, the second connector and the connecting member are relatively fixed in the direction around the central axis.

[0009] With this configuration, the second connector and the connector are relatively fixed in the direction of the central axis by the first limiting structure and the limiting groove, and the second connector and the connector are relatively fixed in the direction around the central axis by the locking member and the locking groove. This ensures that the second connector and the connector are accurately fixed in relative position. Since the connector is connected to the first connector, the first connector and the second connector are accurately fixed in relative position when they are plugged in. The connection structure between the first connector and the second connector is not easy to loosen, and the first connector and the second connector are not easy to disconnect, thus ensuring the stable transmission of radio frequency signals.

Moreover, the first limiting structure 210 and the limiting groove 310 are slidingly connected in the direction around the central axis S, so that the second connecting head 200 and the connecting piece 300 can rotate relative to each other. That is, through the first limiting structure 210 and the limiting groove 310, the relative movement of the second connecting head 200 and the connecting piece 300 in the direction of the central axis S is limited.

[0042] Optionally, the locking groove 211a can be a square groove, a cylindrical groove, etc., and the locking piece 400 can be a block structure, a strip structure, etc., and the embodiments of the present application do not limit the specific structures of the locking groove 211a and the locking piece 400, and it is only required that the locking piece 400 can extend into the locking groove 211a to lock the relative positions of the first limiting structure 210 and the limiting groove 310.

[0043] Referring to FIGS. 1 to 4, the first connecting head 100 and the second connecting head 200 are connected to each other through the connecting piece 300. Figure 2 Figure 3 As shown in FIGS. 1 to 4, when the second connecting head 200 and the connecting piece 300 are relatively rotated to the locking position, the locking groove 211a is opposite to the locking piece 400, and the locking piece 400 can extend into the locking groove 211a to relatively fix the second connecting head 200 and the connecting piece 300. Figure 3 The position of the locking piece 400 in the connecting piece 300 is the position of the locking piece 400 when the locking piece 400 extends into the locking groove 211a.

[0044] In the embodiments of the present application, the radio frequency connector is additionally provided with the connecting piece 300, the connecting piece 300 is connected to the first connecting head 100, and the connecting piece 300 and the second connecting head 200 are connected through special structures to realize the mutual locking of the first connecting head 100 and the second connecting head 200 in the plug-in cooperation state. Specifically, one of the second connecting head 200 and the connecting piece 300 is provided with the first limiting structure 210 and the locking groove 211a, and the other is provided with the limiting groove 310 and the locking piece 400. The first limiting structure 210 extends into the limiting groove 310 to realize the sliding cooperation of the first limiting structure 210 in the limiting groove 310 along the direction around the central axis S, and the first limiting structure 210 and the limiting groove 310 are limited in the direction of the central axis S to realize the rotary cooperation of the second connecting head 200 and the connecting piece 300, and at the same time, the relative movement of the second connecting head 200 and the connecting piece 300 along the central axis S is avoided to separate the second connecting head 200 and the connecting piece 300. Further, when the second connecting head 200 and the connecting piece 300 are relatively rotated to the locking position, the locking piece 400 is opposite to the locking groove 211a, the locking piece 400 can extend into the locking groove 211a, the first limiting structure 210 cannot continue to slide along the limiting groove 310, that is, the second connecting head 200 and the connecting piece 300 are relatively fixed along the direction around the central axis S.

[0045] ​In this way, the first limiting structure 210 and the limiting groove 310 are used to fix the second connector 200 and the connecting piece 300 relative to each other in the direction of the central axis S, and the locking piece 400 and the locking groove 211a are used to fix the second connector 200 and the connecting piece 300 relative to each other in the direction around the central axis S, so that the second connector 200 and the connecting piece 300 are accurately fixed relative to each other. Since the connecting piece 300 is connected to the first connector 100, the first connector 100 and the second connector 200 are accurately fixed relative to each other in the plugged and fitted state, the connection structure of the first connector 100 and the second connector 200 is not easy to loosen, and the first connector 100 and the second connector 200 are not easy to disconnect, thereby ensuring stable transmission of the radio frequency signal.

[0046] In the scheme of the present application, it is referred to Figure 7 and Figure 8 It is shown that the first limiting structure 210 includes a connecting part 211 and a limiting part 212 connected to each other, one of the second connector 200 and the connecting piece 300 is connected to the connecting part 211, and the limiting part 212 protrudes from the surface of the connecting part 211 in the second direction. Optionally, the limiting part 212 protrudes from the first surface of the connecting part 211, the first surface faces away from the central axis S, or the first surface faces the central axis S. The second direction intersects the central axis S, and optionally, the second direction is perpendicular to the central axis S. Of course, the second direction can also intersect the central axis S but not be perpendicular to the central axis S. In the present embodiment, the first connector 100 and the second connector 200 are both circular plugs, and the second direction is the radial direction of the circular plug.

[0047] The connecting part 211 is used to connect the limiting part 212 and the second connector 200, and the connecting part 211 and the limiting part 212 can both be block-shaped structures or strip-shaped structures, and the present application does not limit the specific structures of the connecting part 211 and the limiting part 212. In the present embodiment, the connecting part 211 is a rectangular body structure, the length direction of the rectangular body structure is parallel to the central axis S, and the limiting part 212 is a square structure. The locking groove 211a can be arranged on the connecting part 211 or the limiting part 212, and in the present embodiment, the locking groove 211a is arranged on the surface of the connecting part 211 facing away from the central axis S.

[0048] The connecting part 211 and the second connector 200, and the limiting part 212 and the connecting part 211 can be connected by welding, bonding or the like, and the connecting part 211 and the limiting part 212 can also be an integral structure. Of course, the connecting part 211 can also be used to connect the limiting part 212 and the first connector 100.

[0049] It is referred to Figure 3As shown, the limiting groove 310 includes a first limiting groove 311 and a second limiting groove 312 which are in communication, the first limiting groove 311 is used for the connecting part 211 to extend into, and the second limiting groove 312 is used for the limiting part 212 to extend into, the second limiting groove 312 is opened on the groove wall surface of the first limiting groove 311, the limiting part 212 and the second limiting groove 312 are limitedly matched in the direction of the central axis S, and optionally, the limiting part 212 and the second limiting groove 312 are limitedly contacted in the direction of the central axis S. Optionally, the second limiting groove 312 can be opened on the groove wall surface of the first limiting groove 311 which is relatively close to the central axis S, or can be opened on the groove wall surface of the first limiting groove 311 which is relatively far away from the central axis S.

[0050] In the case that the second connecting head 200 rotates relative to the connecting piece 300, the connecting part 211 and the first limiting groove 311 are slidingly matched, and the limiting part 212 and the second limiting groove 312 are slidingly matched. That is, the matching of the first limiting structure 210 and the limiting groove 310 does not affect the relative rotation process of the connecting piece 300 and the first connecting head 100 or the second connecting head 200.

[0051] By adopting the embodiment, the connecting part 211 and the first limiting groove 311 are matched, and at the same time, the limiting part 212 and the second limiting groove 312 are matched, so that the area of the limiting matching of the first limiting structure 210 and the limiting groove 310 is increased, which is beneficial to the stable relative rotation of the first connecting head 100 and the second connecting head 200, and improves the stability in the process of the rotation matching.

[0052] Optionally, referring to Figure 4 and Figure 5 As shown, the second connecting head 200 or the connecting piece 300 in which the limiting groove 310 is opened is provided with an insertion groove 313 which is in communication with the second limiting groove 312, so that the limiting part 212 can extend into the second limiting groove 312 through the insertion groove 313, and at the same time, the connecting part 211 directly extends into the first limiting groove 311. Further optionally, the insertion groove 313 is located at the first end of the limiting groove 310, and the locking piece 400 is located at the second end of the limiting groove 310, so as to ensure that the first limiting structure 210 can move a larger distance in the limiting groove 310.

[0053] Of course, in other embodiments, the first limiting structure 210 only includes the limiting part 212, the limiting groove 310 is the second limiting groove 312, and the first limiting structure 210 or the limiting groove 310 is directly arranged on the surface of the connecting piece 300 which is away from the central axis S.

[0054] In the optional embodiment, referring to Figure 3As shown, the second connector 200 and the other one of the connecting member 300 are also provided with a sliding groove 320, that is, the first connector 100 or the connecting member 300 provided with the limiting groove 310 is provided with the sliding groove 320, the sliding groove 320 is used for slidingly matching with the locking member 400, the sliding groove 320 is communicated with the limiting groove 310, and optionally, when the locking groove 211a is arranged at the connecting portion 211, the sliding groove 320 is communicated with the first limiting groove 311; when the locking groove 211a is arranged at the limiting portion 212, the sliding groove 320 is communicated with the second limiting groove 312. The locking member 400 comprises a locking rod 410, the locking rod 410 is slidingly matched with the sliding groove 320. When the locking groove 211a is opposite to the locking member 400, the locking groove 211a is communicated with the sliding groove 320, and the locking rod 410 can extend into the locking groove 211a.

[0055] Optionally, the direction in which the locking rod 410 is slidingly matched with the sliding groove 320 is perpendicular to the central axis S, of course, the direction in which the locking rod 410 is slidingly matched with the sliding groove 320 can also intersect with the central axis S but not perpendicular.

[0056] In a further embodiment, the locking member 400 further comprises a pressing end cover 420, the pressing end cover 420 is located outside the sliding groove 320, the pressing end cover 420 is connected with the first end of the locking rod 410, the second end of the locking rod 410 penetrates through the sliding groove 320, the second end of the locking rod 410 can extend into the locking groove 211a, and the other one of the second connector 200 and the connecting member 300 is limitedly matched with the pressing end cover 420. Optionally, the pressing end cover 420 and the locking rod 410 can be a split structure, and the two can be fixedly connected by welding, bonding or the like, or the pressing end cover 420 and the locking rod 410 can be an integral structure.

[0057] By directly manually pressing the pressing end cover 420 from the outside of the sliding groove 320 in the embodiment, the locking rod 410 can directly extend into the locking groove 211a, without the need to additionally add a driving member such as an electric driving member or a pneumatic driving member to drive the locking rod 410 to slide, which is conducive to reducing the number of components and simplifying the structure of the radio frequency connector.

[0058] In the embodiment, the locking member 400 can directly adopt a fastener such as a bolt or a screw, the shank of the fastener as the locking rod 410, and the nut of the fastener as the pressing end cover 420. In this way, the locking member 400 naturally forms the locking rod 410 and the pressing end cover 420 by using existing components, without the need to separately produce the locking member 400, which is conducive to simplifying the process flow of the radio frequency connector.

[0059] In an optional embodiment, after manually pressing the pressing end cover 420 to make the locking rod 410 extend into the locking groove 211a, the pressing end cover 420 can also be manually pulled to make the locking rod 410 disengage from the locking groove 211a, so as to release the locking of the connecting member 300 and the first connector 100 or the second connector 200.

[0060] In another embodiment, the radio frequency connector further comprises a first elastic member 510, which can be but is not limited to a spring. The first elastic member 510 is located in the sliding groove 320 and is sleeved on the outside of the locking rod 410. The first end of the first elastic member 510 is connected to the groove wall surface of the sliding groove 320, and the second end of the first elastic member 510 is connected to the locking rod 410. Alternatively, the first end of the first elastic member 510 and the second end of the first elastic member 510 can be connected to the groove wall surface of the sliding groove 320 and the locking rod 410 by welding, bonding or the like. In this embodiment, the first end of the first elastic member 510 directly abuts against the groove wall surface of the sliding groove 320.

[0061] Alternatively, the sliding groove 320 comprises a slot 321 and a sliding cavity 322 connected in communication. The slot 321, the sliding cavity 322 and the limiting groove 310 are connected in sequence. The locking rod 410 penetrates through the slot 321 and extends into the sliding cavity 322. The first elastic member 510 is located in the sliding cavity 322. The first end of the first elastic member 510 directly abuts against the wall surface of the sliding cavity 322.

[0062] When the pressing end cover 420 is pressed, the locking rod 410 slides relative to the sliding groove 320, and the first elastic member 510 is elastically deformed to accumulate elastic potential energy. When the pressing force disappears, the first elastic member 510 restores the elastic deformation, and the elastic potential energy is released. The first elastic member 510 drives the locking member 400 to reset reversely.

[0063] In this embodiment, the elastic force generated by the first elastic member 510 is directly used as the driving force for resetting the locking member 400, and manual pulling and pressing of the pressing end cover 420 are not required for resetting, which is more conducive to simplifying the unlocking operation process.

[0064] In an optional embodiment, as shown in Figure 3 The radio frequency connector further comprises a limiting structure 411 located in the sliding groove 320. The limiting structure 411 is connected to the locking rod 410 and can be fixedly connected to the locking rod 410 by welding, bonding or the like. When the other one of the second connecting head 200 and the connecting member 300 is in limiting cooperation with the limiting structure 411, the radio frequency connector is in a locked state. The limiting structure 411 is in limiting cooperation with the second connecting head 200 or the connecting member 300 provided with the sliding groove 320, and the locking rod 410 extends into the locking slot 211a. When the other one of the second connecting head 200 and the connecting member 300 is out of limiting cooperation with the limiting structure 411, the radio frequency connector is in an unlocked state. The limiting structure 411 is in sliding cooperation with the sliding groove 320, and the locking rod 410 can be separated from the locking slot 211a.

[0065] The limiting structure 411 can be a limiting plate, a limiting block, etc. The specific structure of the limiting structure 411 is not limited in the embodiments of the present application. Optionally, a groove can be arranged on the wall surface of the sliding groove 320, and the groove can accommodate part of the limiting structure 411. When the locking rod 410 extends into the locking groove 211a, the limiting structure 411 extends into the groove, so that the position of the locking rod 410 relative to the sliding groove 320 is fixed, thereby maintaining the locking state. Of course, other structures except the groove can be arranged to limit the limiting structure 411.

[0066] Optionally, the limiting structure 411 is located in the sliding cavity 322, and the limiting structure 411 protrudes from the surface of the locking rod 410. The second end of the second elastic member 520 can directly abut against the limiting structure 411. The groove can be arranged on the wall surface of the sliding cavity 322.

[0067] By using the embodiment, the state that the locking rod 410 extends into the locking groove 211a can be maintained by the limiting structure 411, the locking state is maintained, and the situation that the locking rod 410 extends into the locking groove 211a and then separates immediately is avoided, thereby improving the stability in the locking state.

[0068] Of course, in other embodiments, the radio frequency connector can not be provided with the limiting structure 411, and the sliding friction between the sliding groove 320 and the locking rod 410 is increased. When a large pressing force is applied to the pressing end cover 420, the locking member 400 slides relative to the sliding groove 320. When the pressing force disappears, the locking member 400 is stationary relative to the sliding groove 320 by the sliding friction, thereby maintaining the state that the locking rod 410 extends into the locking groove 211a.

[0069] In an optional embodiment, the connecting member 300 can have an arc-shaped structure, the number of the limiting groove 310, the first limiting structure 210 and the locking member 400 is one, and the first limiting structure 210 is provided with one locking groove 211a.

[0070] In another embodiment, as shown in Figure 4 and Figure 5 The connecting member 300 includes a connecting ring, the axis of the connecting ring is collinear with the central axis S, and at least two of the limiting groove 310, the first limiting structure 210 and the locking member 400 are arranged at intervals in the circumferential direction of the connecting ring. The first limiting structure 210 corresponds to the limiting groove 310 one by one, each first limiting structure 210 is provided with a locking groove 211a, and the locking member 400 corresponds to the locking groove 211a one by one.

[0071] With the embodiment, the number of the limiting grooves 310 and the first limiting structures 210 is increased, each first limiting structure 210 is limited and matched with each limiting groove 310 one by one, and different regions of the connecting ring are limited and matched with different regions of the second connecting head 200, which is more conducive to improving the stability during the relative rotation of the connecting ring and the second connecting head 200. At the same time, the number of the locking grooves 211a and the locking pieces 400 is also increased accordingly, and different locking pieces 400 can lock different positions, which is more conducive to improving the stability in the locked state and can avoid loosening of the connecting structure of the first connecting head 100 and the second connecting head 200.

[0072] In the scheme of the present application, the first connecting head 100 is used to connect the cable. Optionally, the inside of the first connecting head 100 is provided with the transmission socket 110 and the cable connecting seat 120 described above, and the cable is connected by relying on the cable connecting seat 120. Referring to Figure 9 and Figure 10 As shown in the drawings, the radio frequency connector further comprises an elastic wire clamping piece 710, a pressing piece 720 and a pulling piece 800. The elastic wire clamping piece 710 is used to clamp or release the cable. The elastic wire clamping piece 710 has elastic performance, so that it can produce elastic deformation to adjust the size of the passage for the cable to pass through, thereby realizing clamping or releasing the cable. The pressing piece 720 is used to press the elastic wire clamping piece 710 to make it produce elastic deformation. The pulling piece 800 is used to pull the pressing piece 720 to move.

[0073] The elastic wire clamping piece 710 can be but is not limited to a plate structure, and can be a flat plate structure or an arc-shaped plate structure. The material of the elastic wire clamping piece 710 can be plastic or other materials with elasticity. The elastic wire clamping piece 710 is connected with the first connecting head 100. The elastic wire clamping piece 710 and the first connecting head 100 can be directly connected by welding, bonding or other methods, or the elastic wire clamping piece 710 and the first connecting head 100 can be indirectly connected through other components, as long as the elastic wire clamping piece 710 is fixed relative to the first connecting head 100.

[0074] The pressing piece 720 is located on the side of the elastic wire clamping piece 710 away from the central axis S. The elastic wire clamping piece 710 is provided with a pressure receiving surface 711, which faces the pressing piece 720. The pressing piece 720 can conveniently exert a force on the pressure receiving surface 711 of the elastic wire clamping piece 710 to make the elastic wire clamping piece 710 produce deformation towards the central axis S along the first direction C. The distance between the pressure receiving surface 711 and the central axis S decreases, and the distance between the pressure receiving surface 711 and the pressing piece 720 increases. That is to say, along the first direction C, the thickness of the elastic wire clamping piece 710 decreases. Optionally, along the first direction C, the distance between the surface of the elastic wire clamping piece 710 away from the pressure receiving surface 711 and the central axis S is constant.

[0075] Further, the extrusion piece 720 is in sliding connection with the first connector 100 along a first direction C, which is parallel to the central axis S. Alternatively, the extrusion piece 720 and the first connector 100 can be in sliding connection through sliding rails and sliding blocks in sliding fit. Of course, the two can also be in sliding connection through other structures.

[0076] The pulling piece 800 is located outside the first connector 100. The pulling piece 800 is connected with the extrusion piece 720. A user directly manually acts on the pulling piece 800 to pull the extrusion piece 720 to slide relative to the first connector 100 along the first direction C. Alternatively, the radio frequency connector further comprises a connecting rod 810. A first end of the connecting rod 810 is connected with the pulling piece 800. A second end of the connecting rod 810 is connected with the extrusion piece 720. Further alternatively, the first end of the connecting rod 810 and the pulling piece 800 and the second end of the connecting rod 810 and the extrusion piece 720 can be fixedly connected through welding, bonding or the like. Of course, a part of the pulling piece 800 can also extend into the first connector 100 to be directly connected with the extrusion piece 720.

[0077] Specifically, in the initial state, the extrusion piece 720 acts on the region with a larger thickness of the elastic clamping piece 710. The elastic clamping piece 710 produces a larger elastic deformation. At this time, the elastic clamping piece 710 tightens the cable. When the pulling piece 800 pulls the extrusion piece 720 to slide along the first direction C, the extrusion piece 720 acts on the pressure surface 711. Since the pressure surface 711 gradually moves away from the extrusion piece 720, the extrusion piece 720 exerts a decreasing force on the elastic clamping piece 710. The elastic deformation of the elastic clamping piece 710 decreases. The force exerted by the elastic clamping piece on the cable also gradually decreases until the cable is completely released, indicating that the cable can be detached from the first connector 100. Conversely, when the extrusion piece 720 slides in the opposite direction of the first direction C, since the pressure surface 711 gradually approaches the extrusion piece 720, the extrusion piece 720 exerts an increasing force on the elastic clamping piece 710. The elastic deformation of the elastic clamping piece 710 increases. The force exerted by the elastic clamping piece on the cable also gradually increases to gradually tighten the cable.

[0078] By adopting the embodiment, the elastic clamping piece 710, the extrusion piece 720 and the pulling piece 800 are provided. The cable can be tightened or released as needed. The cable can be quickly disassembled. The flexibility and reliability of the connection are enhanced. Further, the tightness of the clamped cable can be adjusted by pulling the pulling piece 800. Based on this, when the first connector 100 and the second connector 200 are unlocked and plugged together, the first connector 100 can be disassembled. Therefore, the user can replace the first connector 100 as needed.

[0079] In addition, the second connector 200 can be separately disassembled when the second connector 200 is disconnected from the electronic device and the first connector 100 and the second connector 200 are disconnected and plugged together, so that the user can replace the second connector 200 as needed.

[0080] Therefore, the radio frequency connector in the embodiment of the present application can install and disassemble the first connector 100 and the second connector 200 as needed, and when damage occurs, the first connector 100 or the second connector 200 can be replaced separately according to the use condition, without the need to replace the entire radio frequency connector, thereby reducing the cost, the replacement operation is relatively simple, and it is also beneficial to prolong the service life of the radio frequency connector.

[0081] In an optional embodiment, referring to Figure 10 The radio frequency connector further includes a guide mechanism 600, the guide mechanism 600 includes a guide block 610, a guide rod 620, and a connecting block 630, the guide block 610 is connected with the first connector 100, and the guide block 610 and the first connector 100 can be fixedly connected by welding, bonding or the like. Moreover, the guide block 610 is provided with a guide groove 611, the guide rod 620 is located in the guide groove 611, the guide rod 620 extends along the first direction C, and the two ends of the guide rod 620 are connected with the groove walls of the guide groove 611 respectively. Optionally, the two groove walls opposite to each other of the guide groove 611 are provided with a cylindrical groove respectively, and the two ends of the guide rod 620 extend into the corresponding cylindrical grooves respectively, so that the guide rod 620 is suspended, and the guide rod 620 is fixed relative to the guide block 610.

[0082] The connecting block 630 is sleeved on the outside of the guide rod 620, the guide rod 620 and the connecting block 630 are in sliding fit, and the connecting block 630 is connected with the extrusion piece 720. The connecting block 630 is used for supporting and limiting the extrusion piece 720. Optionally, the first end of the connecting block 630 is provided with a through hole, the guide rod 620 penetrates through the through hole, and the second end of the connecting block 630 is fixedly connected with the extrusion piece 720 by welding, bonding or the like.

[0083] By using the guide mechanism 600, the extrusion piece 720 is slidably connected with the first connector 100, and the guide mechanism 600 guides the movement direction of the extrusion piece 720, which is beneficial to the accurate sliding of the extrusion piece 720 relative to the first connector 100 along the first direction C and avoids the deviation of the sliding direction.

[0084] In an optional embodiment, the number of the guide mechanism 600 is one.

[0085] In another embodiment, referring to Figure 10As shown, the guide mechanisms 600 are arranged in multiple numbers in the direction around the middle axis S, that is, the numbers of the guide blocks 610, the guide rods 620 and the connecting blocks 630 are all multiple. Alternatively, the guide mechanisms 600 can be uniformly distributed or unevenly distributed in the direction around the middle axis S.

[0086] By the embodiment, the number of the guide mechanisms 600 is increased, different positions of the extrusion member 720 are respectively connected with different guide mechanisms 600 and different positions of the first connecting head 100, which is more conducive to improving the stability of the extrusion member 720 in the sliding process. Meanwhile, the multiple guide mechanisms 600 respectively apply guidance to different regions of the extrusion member 720, which is more conducive to the overall accurate sliding of the extrusion member 720 in the first direction C relative to the first connecting head 100, and further avoids the deviation of the sliding direction.

[0087] In an alternative embodiment, when the pulling member 800 pulls the extrusion member 720 to slide in the first direction C to a certain position, the pulling member 800 can be manually pressed to drive the extrusion member 720 to slide in the reverse direction of the first direction C, so as to reset the extrusion member 720 and the pulling member 800.

[0088] In another embodiment, referring to Figure 10 As shown, the radio frequency connector further comprises a second elastic member 520, which can be but is not limited to a spring. The second elastic member 520 is sleeved outside the guide rod 620, and two ends of the second elastic member 520 are respectively connected with the guide block 610 and the connecting block 630. Alternatively, the first end of the second elastic member 520 and the guide block 610, and the second end of the second elastic member 520 and the connecting block 630 can be fixedly connected by welding, bonding or the like. In the embodiment, the first end of the second elastic member 520 directly abuts against the guide block 610, and the second end of the second elastic member 520 directly abuts against the connecting block 630, avoiding complex connection operations.

[0089] In the case that the pulling member 800 pulls the extrusion member 720 to slide relative to the first connecting head 100 in the first direction C, the second elastic member 520 is elastically deformed, and the second elastic member 520 accumulates elastic potential energy. When the pulling force of the pulling member 800 on the extrusion member 720 disappears, the elastic potential energy is released, the second elastic member 520 restores the elastic deformation, and the second elastic member 520 drives the extrusion member 720 to slide in the reverse direction of the first direction C, so as to reset the extrusion member 720 and the pulling member 800.

[0090] Optionally, the second elastic member 520 can be located on the side of the connecting block 630 away from the pulling member 800, and in the case that the extruding member 720 slides along the first direction C, the second elastic member 520 is in a stretched state; or the second elastic member 520 can be located on the side of the connecting block 630 facing the pulling member 800, and in the case that the extruding member 720 slides along the first direction C, the second elastic member 520 is in a compressed state.

[0091] By using the elastic force generated by the second elastic member 520 as the driving force for resetting the extruding member 720, the embodiment eliminates the need for manually pressing the pulling member 800 for resetting, and is more conducive to simplifying the resetting operation process.

[0092] Optionally, the number of the second elastic members 520 is multiple, and at least one second elastic member 520 is arranged in each guide slot 611, and in the embodiment, the second elastic member 520 corresponds to the guide mechanism 600 one by one. In this way, the number of the second elastic members 520 is increased, and each second elastic member 520 drives the corresponding connecting block 630 to move, so as to apply a resetting force to different areas of the extruding member 720, which is more conducive to accurately resetting the extruding member 720.

[0093] In an optional embodiment, the number of the elastic wire clamping members 710 is one.

[0094] In another embodiment, as shown in Figure 9 In the circumferential direction of the central axis S, the elastic wire clamping members 710 are arranged at intervals, and the plurality of elastic wire clamping members 710 form a wire clamping channel 712. In the case that the pulling member 800 pulls the extruding member 720 to slide along the first direction C, the wire clamping channel 712 gradually increases in wire passing area. Conversely, in the case that the extruding member 720 slides along the reverse direction of the first direction C, the wire clamping channel 712 gradually decreases in wire passing area. That is, in the process of the extruding member 720 sliding along the first direction C, the cable is gradually loosened; and in the process of the extruding member 720 sliding along the reverse direction of the first direction C, the elastic wire clamping members 710 gradually clamp the cable. The plurality of elastic wire clamping members 710 can be uniformly distributed or non-uniformly distributed in the circumferential direction of the central axis S.

[0095] Optionally, the first connecting head 100 is provided with a wire passing hole 100a, the wire clamping channel 712 communicates with the wire passing hole 100a, and the pulling member 800 is located on the side of the wire passing hole 100a away from the wire clamping channel 712, and the pulling member 800 is in reverse limiting cooperation with the first connecting head 100 along the first direction C.

[0096] By using the elastic wire clamping members 710, the number of the elastic wire clamping members 710 is increased, and the plurality of elastic wire clamping members 710 simultaneously generate elastic deformation and act on the cable, which is more conducive to timely tightening and releasing the cable, and is more convenient for installing and dismounting the cable.

[0097] In the embodiment, the number of the elastic thread clamping members 710 can be four, and the elastic thread clamping members 710, the guide mechanism 600 and the second elastic member 520 correspond to each other respectively. Of course, the elastic thread clamping members 710 can also be other numbers.

[0098] In an alternative embodiment, the extrusion member 720 can be an extrusion sleeve, that is, the extrusion member 720 is a ring structure, the extrusion sleeve is sleeved outside the elastic thread clamping member 710, and the axis of the extrusion sleeve is collinear with the middle axis S. In this way, when the extrusion sleeve slides along the first direction C, the extrusion sleeve simultaneously extrudes multiple elastic thread clamping members 710. Along the first direction C, the distance from the inner wall surface of the extrusion sleeve to the middle axis S is constant.

[0099] In another embodiment, along the first direction C, the distance from the inner wall surface of the extrusion sleeve to the middle axis S decreases. That is, along the first direction C, the thickness of the extrusion sleeve decreases. Alternatively, along the first direction C, the distance from the outer wall surface of the extrusion sleeve to the middle axis S is constant.

[0100] In this way, during the sliding process of the extrusion member 720 along the first direction C, the position with smaller thickness of the extrusion member 720 corresponds to the position with smaller thickness of the elastic thread clamping member 710, which is beneficial to the extrusion member 720 to release the elastic thread clamping member 710 more timely, and the extrusion member 720 no longer acts on the elastic thread clamping member 710, which is beneficial to the elastic thread clamping member 710 to release the cable in time; similarly, during the reverse sliding process of the extrusion member 720 along the first direction C, the position with larger thickness of the extrusion member 720 corresponds to the position with larger thickness of the elastic thread clamping member 710, which is beneficial to the extrusion member 720 to further extrude the elastic thread clamping member 710, to increase the elastic deformation degree of the elastic thread clamping member 710, to make the elastic thread clamping member 710 further deform in the direction close to the middle axis S, and to be more beneficial to the elastic thread clamping member 710 to tighten the cable in time.

[0101] The embodiments of the application are described above with reference to the drawings; however, the application is not limited to the specific embodiments described above, which are only illustrative rather than limiting, and a person of ordinary skill in the art can make many forms under the inspiration of the application without departing from the purpose of the application and the scope protected by the claims.
