[0001] The present invention relates to the technical field of radio frequency coaxial connectors, and specifically to an assembly machine for a tin phosphor bronze radio frequency coaxial connector, an assembly method, and a radio frequency coaxial connector applicable to the assembly machine. Background Technique

[0002] Among the various components of a radio frequency coaxial connector, the ferrule, the body, the center pin, the solder cup, and the tail tube are all metal products. Beryllium bronze, tin phosphor bronze, brass, and stainless steel are common precious metal materials in radio frequency coaxial connectors, each having its own advantages.

[0003] Among them, due to the certain soft characteristics of tin phosphor bronze, it has become a substitute for other various copper alloy precious metal materials. When the beryllium bronze material must be used due to extremely high electrical performance, tin phosphor bronze can be used as a substitute considering other performance aspects. In terms of the characteristics of the material itself, tin phosphor bronze has good corrosion resistance, mechanical properties, and processing properties; in terms of usage characteristics, tin phosphor bronze can be applied to larger jacks, elastic contacts, or outer conductors.

A rotating ring is rotatably installed on the rotating sleeve. A first connecting rod hinged to the third sliding block is hinged on the rotating ring. A second connecting rod hinged to the first sliding block is hinged on the rotating sleeve.

[0013] As a further solution of the present invention: The follower rotation assembly includes a through groove opened on the circumferential outer wall of the hollow rod. A limiting ring penetrating through the through groove is provided on the support rod. A first spring and a second spring are sleeved on the hollow rod.

It further includes a guiding groove opened on the support rod. A limiting block slidably fitted with the guiding groove is arranged inside the hollow rod.

[0014] An assembling method of a tin phosphor bronze radio frequency coaxial connector includes the following steps: Step 1: The lower clamping assembly controls the clamping plate to limit some components of the connector. Meanwhile, the clamping plate clamps another part of the components of the connector. Step 2: Under the action of the lifting assembly, the upper clamping assembly controls the clamping plate to move towards the clamping plate direction to control the mutual insertion of the two components. Step 3: When the clamping plate moves to the end of the stroke, the lifting assembly will control the follower rotation assembly to move, so as to control the inserted assembly to rotate a certain angle through the clamping plate. Step 4: After the insertion is completed, the lifting assembly controls the clamping plate to reset to apply a pulling force to the connector.

[0015] A radio frequency coaxial connector includes: A base, and an outer conductor and an inner conductor installed on the base. A housing is sleeved on the outer conductor.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: After the nesting member is successfully inserted into the plug-in member under the control of the upper clamping assembly in this application, it rotates a certain angle to complete the assembly of the connector. During the reset process of the clamping plate, a pulling force is synchronously provided to the nesting member to test the insertion strength of the connector. Specifically, the lower clamping assembly controls the clamping plate to limit the plug-in member, and the upper clamping assembly controls the clamping plate to clamp the nesting member. At this time, under the action of the lifting assembly, the upper clamping assembly controls the clamping plate to move towards the clamping plate to control the nesting member to be sleeved on the plug-in member. When the clamping plate descends to the maximum depth, under the action of the follow-up rotation assembly, the clamping plate controls the nesting member to rotate a certain angle to complete the insertion. At this time, the lifting assembly provides a certain pulling force to the nesting member through the upper clamping assembly and the clamping plate. If the plug-in member and the nesting member are inserted in place, the assembled connector will not separate. If the nesting member and the plug-in member are not inserted in place, when the clamping plate provides a pulling force to the nesting member, the nesting member will separate from the plug-in member. Through the above operations, the assembly of the connector is realized, and after the assembly is completed, the plug and unplug quality of the connector is detected to ensure that the connector is assembled in place.

[0018] After the nesting member and the plug-in member are inserted, during the reset stage of the clamping plate, a pulling force can be provided to the nesting member, so that after the assembly is completed, the insertion strength between the nesting member and the plug-in member can be directly tested. Without additional equipment or complex operation processes, it is possible to intuitively judge whether the insertion of the two is firm and reliable, effectively ensuring the overall performance and quality stability of the connector.

[0019] Through the above series of operation designs and structural combinations, not only the smooth progress of the assembly process is guaranteed, but also the subsequent detection process is greatly simplified, reducing the time and labor costs of the detection link, thus significantly increasing the overall efficiency of the connector assembly.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, and it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manners.

[0037] Please refer to Figures 1 to 14 , in the embodiment of the present invention, an assembly machine for a tin-phosphor bronze radio frequency coaxial connector includes: Processing table 1, as well as a fixing plate 2 and a supporting plate 9 fixed on the processing table 1. A conveying component is arranged on the fixing plate 2. The conveying component includes belt pulleys rotatably installed on the fixing plate 2 and symmetrically arranged, and a conveyor belt 3 is sleeved on the belt pulleys; It further includes: A lower clamping component, arranged on the processing table 1. The lower clamping component includes clamping plates 8 symmetrically arranged; A lifting component, arranged on the supporting plate 9. An upper clamping component is arranged on the lifting component. The upper clamping component includes clamping plates 20 symmetrically arranged. The lifting component drives the clamping plates 20 to move in the vertical direction through the upper clamping component; A spacing adjustment mechanism, arranged on the supporting plate 9 and connected to the upper clamping component. The spacing adjustment mechanism can adjust the spacing between the clamping plates 20 when the upper clamping component moves; A follow-up rotation component, arranged on the lifting component and connected to the spacing adjustment mechanism. The follow-up rotation component can drive the clamping plates 20 to rotate when the lifting component moves.

[0038] Specifically, the assembly of the connector can be divided into two parts, namely the plug-in part and the sleeve part. The lower clamping component controls the clamping plates 8 to limit the plug-in part, and the upper clamping component controls the clamping plates 20 to clamp the sleeve part. At this time, under the action of the lifting component, the upper clamping component controls the clamping plates 20 to move towards the clamping plates 8 to control the sleeve part to be sleeved on the plug-in part. When the clamping plates 20 descend to the maximum depth, under the action of the follow-up rotation component, the clamping plates 20 control the sleeve part to rotate a certain angle to complete the insertion. At this time, the lifting component provides a certain pulling force to the sleeve part through the upper clamping component and the clamping plates 20. Since the plug-in part limited by the clamping plates 8 is still in the limited state, the sleeve part has a tendency to move away from the plug-in part. If the plug-in part and the sleeve part are inserted in place, the assembled connector will not separate. After the lifting component moves to a certain position, the upper clamping component is controlled to move through the spacing adjustment mechanism, so that the two clamping plates 20 move away from each other to release the sleeve part. If the sleeve part and the plug-in part are not inserted in place, when the clamping plates 20 provide a pulling force to the sleeve part, the sleeve part will separate from the plug-in part. At this time, the sleeve part can be clamped by a manipulator, and after the lifting component rises to a certain height, the sleeve part is released. The manipulator can transfer the sleeve part. By mutually clamping and limiting the plug-in part and the sleeve part, the assembly of the connector can be realized, and after the assembly is completed, the plugging and unplugging quality of the connector is detected to ensure that the connector is assembled in place.

[0039] Please refer to Figure 1 、 Figure 2 、Figure 5 , the lower clamping assembly includes a guide post 4 installed on the processing table 1, symmetrically arranged guide sleeves 5 are slidably installed on the guide post 4, a movable plate 6 is arranged on the guide sleeve 5, the movable plate 6 is connected to the clamping plate 8, and a cylinder 7 connected to the movable plate 6 is arranged on the processing table 1.

[0040] Specifically, in the initial state, under the action of the cylinder 7, the guide sleeve 5 is controlled by the movable plate 6 to be at the end of the stroke away from the fixed plate 2, so that the distance between the two clamping plates 8 is the largest. When the connector to be assembled is conveyed by the conveyor belt 3 to the position where it cooperates with the clamping plate 8, the cylinder 7 works, and the guide sleeve 5 is controlled by the movable plate 6 to move along the length direction of the guide post 4. The guide sleeve 5 will also drive the two clamping plates 8 to move towards each other until the clamping plates 8 limit the bottom of the connector and provide a certain clamping force to the side of the connector. At this time, the connector cannot move in the resin direction but can rotate freely to facilitate subsequent assembly.

[0041] Please refer to Figures 1 - 3 , Figure 7 , Figure 8 , the lifting assembly includes a guide rail 11 installed on the support plate 9, a motor 12 is arranged on the processing table 1, a lead screw 13 connected to the output shaft of the motor 12 is rotatably installed on the support plate 9, a threaded sleeve 14 threadedly connected to the lead screw 13 and slidably connected to the guide rail 11 is arranged on the lead screw 13, and a fixing ring 15 is arranged on the side wall of the threaded sleeve 14.

[0042] It should be noted that after the clamping plate 20 clamps the sleeve, it is necessary to control the sleeve to move towards the connector. At this time, the motor 12 works and drives the lead screw 13 to rotate, thereby driving the threaded sleeve 14 to move along the length direction of the guide rail 11. The guide rail 11 has a guiding function to ensure that the threaded sleeve 14 does not rotate along with the lead screw 13 during movement. The threaded sleeve 14 will also drive the fixing ring 15 to move, so as to control the sleeve to move towards the connector through the upper clamping assembly and the clamping plate 20.

[0043] Please refer to Figures 1 - 4 , Figures 6 - 9, the upper clamping assembly includes a hollow rod 16 installed on the fixed ring 15. A support rod 17 is slidably installed in the hollow rod 16. A rotating plate 18 is provided at the end of the support rod 17. Symmetrically arranged first sliding grooves 1801 are formed on the rotating plate 18. First sliding blocks 19 are slidably installed in the first sliding grooves 1801. The first sliding blocks 19 are connected to the clamping plates 20. The spacing adjustment mechanism includes symmetrically arranged guide grooves formed on the support plate 9. Guide rods 10 are rotatably installed in the guide grooves. It further includes a first connecting plate 21 installed on the hollow rod 16. Symmetrically arranged second sliding grooves 2101 are formed on the first connecting plate 21. Second sliding blocks 22 are slidably installed in the second sliding grooves 2101. A limiting post 23 that is slidably fitted with the guide groove is provided on the second sliding blocks 22. A driven assembly connected to the second sliding blocks 22 is provided on the support rod 17. Among them, the driven assembly includes a second connecting plate 24 rotatably installed on the support rod 17. Symmetrically arranged third sliding grooves 2401 are formed on the second connecting plate 24. Third sliding blocks 25 are slidably installed in the third sliding grooves 2401. A support post 26 that penetrates the second sliding blocks 22 is provided on the third sliding blocks 25. It further includes a rotating sleeve 27 slidably installed on the support rod 17. A rotating ring 2701 is rotatably installed on the rotating sleeve 27. A first connecting rod 28 that is hinged to the third sliding blocks 25 is hinged on the rotating ring 2701. A second connecting rod 29 that is hinged to the first sliding blocks 19 is hinged on the rotating sleeve 27.

[0044] Furthermore, the guide groove can be divided into five sections, namely a first vertical groove 901, a first inclined groove 902, a second vertical groove 903, a second inclined groove 904, and a limiting groove 905. One end of the first inclined groove 902 is connected to the end of the second vertical groove 903, and the other end is connected to the first vertical groove 901. Both ends of the second inclined groove 904 are respectively connected to the ends of the first vertical groove 901 and the second vertical groove 903. The limiting groove 905 is located at the connection position of the first inclined groove 902 and the first vertical groove 901. The guide rod 10 is located in the limiting groove 905. A torsion spring is sleeved on the rotating shaft of the guide rod 10. Under the action of the torsion spring, the guide rod 10 is parallel to the first inclined groove 902 and blocks the first vertical groove 901. Before assembling the connector, the limiting post 23 is located at the connection position of the second vertical groove 903 and the first inclined groove 902, making the distance between the two second sliding blocks 22 the smallest, so as to control the distance between the two third sliding blocks 25 to be the smallest through the support post 26. The third sliding blocks 25 will control the rotating sleeve 27 to be at the end of the stroke towards the rotating plate 18 through the first connecting rod 28 and the rotating ring 2701, so as to control the distance between the two first sliding blocks 19 and the clamping plates 20 to be the largest through the second connecting rod 29. Subsequently, the fitting to be assembled can be transported to the highest point that the clamping plate 20 can rise by a manipulator. At the same time, under the action of the lifting assembly, the fixed ring 15 is controlled to move away from the fixed plate 2, thereby driving the hollow rod 16 to move. Under the action of the follow-up rotation assembly, the support rod 17 moves synchronously, thereby driving the rotating plate 18 to move, so as to control the clamping plate 20 to rise. The hollow rod 16 will also drive the first connecting plate 21 to move, thereby driving the limiting column 23 to move along the length direction of the second vertical groove 903 through the second sliding block 22. When the limiting column 23 disengages from the second vertical groove 903 and enters the second inclined groove 904, the two second sliding blocks 22 will move away from each other, thereby driving the third sliding block 25 to move away from each other through the support column 26. The third sliding block 25 will control the rotating sleeve 27 to move away from the rotating plate 18 through the first connecting rod 28 and the rotating ring 2701, so as to reduce the distance between the first sliding block 19 and the clamping plate 20 through the second connecting rod 29. When the limiting column 23 moves to the connection position of the second inclined groove 904 and the first vertical groove 901, and the clamping plate 20 rises to the position where it cooperates with the manipulator, the motor 12 stops working. The distance between the clamping plates 20 reaches the minimum, and the fitting is clamped, and the manipulator can withdraw; At this time, the motor 12 controls the screw rod 13 to reverse, so as to control the hollow rod 16 to move towards the fixed plate 2. Under the action of the follow-up rotation assembly, the support rod 17 is controlled to move synchronously with the hollow rod 16, and the first sliding block 19 is driven to move through the rotating plate 18, so as to drive the fitting to move through the clamping plate 20. At the same time, the limiting column 23 will slide along the first vertical groove 901 to ensure that the distance between the clamping plates 20 remains unchanged. When the limiting column 23 abuts against the guiding rod 10, the guiding rod 10 will give way and block the first inclined groove 902. The limiting column 23 will continue to slide along the first vertical groove 901. Under the action of the torsion spring, the guiding rod 10 will reset. When the depth of the fitting inserted into the plug-in part reaches the maximum, the positions of the clamping plate 20 and the support rod 17 will no longer change. The screw rod 13 continues to rotate, so that the size of the sleeve joint between the hollow rod 16 and the support rod 17 increases. Under the action of the follow-up rotation assembly, the support rod 17 rotates, so as to drive the rotating plate 18 to rotate. Under the action of the rotating plate 18, the fitting is controlled to rotate through the clamping plate 20, so that the fitting and the plug-in part are inserted into each other to complete.

[0045] After the insertion is completed, the lifting assembly controls the hollow rod 16 to move away from the fixed plate 2. If the insert and the fitting are firmly inserted, under the action of the follow-up rotation assembly, the support rod 17 will not move with the hollow rod 16, and a force is provided to the fitting to move away from the insert through the clamping plate 20 to test the insertion strength. The limit post 23 slides along the first vertical groove 901, and the distance between the first connecting plate 21 and the second connecting plate 24 gradually increases. When the limit post 23 moves to the position where it abuts against the guide rod 10, since the first vertical groove 901 is blocked, the limit post 23 will enter the first inclined groove 902, causing the clamping plates 20 to move away from each other and releasing the fitting. At this time, the insertion strength test of the combined connector is completed. If the insert and the fitting are loosely inserted, under the action of the follow-up rotation assembly, the support rod 17 will move with the hollow rod 16 to drive the fitting to disengage from the insert through the clamping plate 20. The manipulator can move to the grasping position. When the limit post 23 disengages from the first vertical groove 901 and enters the first inclined groove 902, the fitting is released, and the manipulator can grasp the released fitting.

[0046] Preferably, with the excellent cooperation between the limit post 23 and the guiding groove, it can be ensured that during the entire descending stroke of the clamping plate 20, the distance between the clamping plates 20 always remains constant without any change. This characteristic is crucial for the smooth assembly of the connector, effectively avoiding assembly errors or failures caused by the change in the distance between the clamping plates 20, and significantly improving the assembly accuracy and reliability.

[0047] Meanwhile, when the fitting and the insert are inserted, during the reset stage of the clamping plate 20, this structural design can provide a stable pulling force for the fitting. The application of this pulling force enables the direct testing of the insertion strength between the fitting and the insert after the assembly is completed. Without additional equipment or complex operation procedures, it is possible to intuitively judge whether the two are firmly inserted, effectively ensuring the overall performance and quality stability of the connector.

[0048] Through the above series of operation designs and structural combinations, not only is the smooth progress of the assembly process guaranteed, but also the subsequent detection process is greatly simplified, reducing the time and labor costs of the detection link, thereby significantly increasing the overall efficiency of the connector assembly.

[0049] Please refer to Figures 1 - 3 、 Figures 7 - 10, the follower rotation assembly includes a through groove 1601 formed on the circumferential outer wall of the hollow rod 16, a limiting ring 1705 penetrating through the through groove 1601 is arranged on the support rod 17, a first spring 30 and a second spring 31 are sleeved on the hollow rod 16, two ends of the first spring 30 are respectively abutted against the fixed ring 15 and the limiting ring 1705, two ends of the second spring 31 are respectively abutted against the limiting ring 1705 and the first connecting plate 21; it further includes a guiding groove formed on the support rod 17, and a limiting block 1602 slidably engaged with the guiding groove is arranged in the hollow rod 16.

[0050] Furthermore, the guiding groove can be divided into four sections, namely a first straight groove 1701, a first spiral groove 1702, a second straight groove 1703, and a second spiral groove 1704. Two ends of the first spiral groove 1702 are respectively connected to the ends of the first straight groove 1701 and the second straight groove 1703. One end of the second spiral groove 1704 is connected to the end of the second straight groove 1703, and the other end is connected to the first straight groove 1701. In the initial state, the first spring 30 and the second spring 31 are in a compressed state, and the forces provided by the first spring 30 and the second spring 31 to the limiting ring 1705 cancel each other out, so that the dimension of the mutual nesting of the support rod 17 and the hollow rod 16 remains unchanged. The limiting block 1602 is located in the first straight groove 1701 and above the second spiral groove 1704. Under the action of the first spring 30 and the second spring 31, when the hollow rod 16 moves towards the fixing plate 2, the support rod 17 moves synchronously with the hollow rod 16. When the fitting is completely inserted into the socket, the positions of the support rod 17 and the clamping plate 20 no longer change. At this time, the hollow rod 16 continues to move, so that the first spring 30 is compressed and the second spring 31 is elastically released. At the same time, the limiting block 1602 is controlled to slide along the first straight groove 1701. When the limiting block 1602 disengages from the first straight groove 1701 and enters the first spiral groove 1702, the support rod 17 will rotate, thereby driving the clamping plate 20 to move through the rotating plate 18, so that the fitting rotates a certain angle to ensure the smooth assembly of the fitting and the socket.

[0051] After assembly, under the action of the lifting assembly, the hollow rod 16 is controlled to move towards the initial position. At this time, the first spring 30 is elastically released, the second spring 31 is compressed, and the position of the support rod 17 remains unchanged. At the same time, the limiting block 1602 moves along the second straight groove 1703. If the fitting and the plug-in part are firmly inserted, when the limiting block 1602 disengages from the second straight groove 1703 and enters the second spiral groove 1704, the support rod 17 rotates towards the initial angle, and the fitting and the plug-in part are synchronously rotated through the clamping plate 20 until the limiting block 1602 returns to the first straight groove 1701 and the force received by the limiting ring 1705 is balanced again. The lifting assembly continues to move to provide a pulling force to the fitting through the clamping plate 20, thereby testing the insertion strength of the connector. If the fitting and the plug-in part are loosely inserted, when the limiting block 1602 returns to the first straight groove 1701, the clamping plate 20 will drive the fitting to move synchronously.

[0052] Preferably, through the cooperation of the limiting block 1602 and the guiding groove, when the fitting is completely sleeved on the plug-in part, the fitting can be controlled to rotate a certain angle to ensure that the fitting is smoothly assembled with the plug-in part.

[0053] An assembly method of a tin-phosphor bronze radio frequency coaxial connector includes the following steps: Step 1: The clamping plate 8 is controlled by the lower clamping assembly to limit some components of the connector. At the same time, some other components of the connector are clamped by the clamping plate 20. Step 2: Under the action of the lifting assembly, the clamping plate 20 is controlled by the upper clamping assembly to move towards the clamping plate 8 to control the mutual insertion of the two components. Step 3: When the clamping plate 20 moves to the end of the stroke, the lifting assembly will control the movement of the follower rotation assembly to rotate the inserted components by a certain angle through the clamping plate 20. Step 4: After the insertion is completed, the lifting assembly controls the clamping plate 20 to reset to apply a pulling force to the connector. When the pulling force reaches a certain value, under the action of the spacing adjustment mechanism, the clamping plate 20 is controlled to move in the direction away from each other.

[0054] A radio frequency coaxial connector includes: A base 3201, an outer conductor 32 and an inner conductor 33 installed on the base 3201, and a housing 34 sleeved on the outer conductor 32; Please refer to Figures 11 - 14, a plug-in locking component, is arranged on the outer shell 34 and connected to the outer conductor 32 for fixing the outer shell 34 on the outer conductor 32. The plug-in locking component includes positioning grooves formed on the inner wall of the outer shell 34 and distributed at equal circumferential intervals. A movable disk 35 in contact with the outer conductor 32 is slidably installed in the outer shell 34, and a third spring 36 in contact with the movable disk 35 is arranged in the outer shell 34; It further includes an inclined rod 37 slidably installed on the outer conductor 32 and slidably matched with the positioning groove. A fixing rod 38 is arranged on the inner conductor 33, and a fourth spring 39 in contact with the inclined rod 37 is sleeved on the fixing rod 38.

[0055] Among them, the positioning groove can be divided into multiple segments, namely an arc-shaped groove 3401, a vertical groove 3402, an annular groove 3403, and a limiting hole 3404. The arc-shaped groove 3401 is formed at the end of the outer shell 34. The most concave position of the arc-shaped groove 3401 is connected to one end of the vertical groove 3402. The other end of the vertical groove 3402 is connected to one end of the annular groove 3403. The limiting hole 3404 is located at the other end of the annular groove 3403 and penetrates the outer shell 34. The connection position between the arc-shaped groove 3401 and the vertical groove 3402 is arranged in an inclined stepped shape. The third spring 36 is in a compressed state, so that the movable disk 35 is located at the end of the stroke on the side facing the arc-shaped groove 3401. A follower ring 3701 in contact with the inner wall of the outer conductor 32 is arranged on the inclined rod 37. The fourth spring 39 is also in a compressed state, so that the inclined rod 37 is located at the end of the stroke in the direction away from the inner conductor 33, and the end of the inclined rod 37 is arranged in an inclined shape.

[0056] In this application, the outer shell 34 is the above-mentioned fitting. The inner conductor 33, the outer conductor 32 and the base 3201 are combined to form a plug-in connector. Therefore, when assembling the connector, the base 3201 can be placed on the conveyor belt 3 and moved to the position matching with the clamping plate 20. Under the action of the clamping plate 8, the base 3201 is limited, and a certain clamping force is provided to the outer conductor 32. At the same time, the clamping plate 20 can clamp the outer shell 34 and make one side of the arc-shaped groove 3401 face the direction of the conveyor belt 3. When the outer shell 34 is sleeved on the outer conductor 32, the arc-shaped groove 3401 will first abut against the inclined rod 37. Since the clamping force on the outer shell 34 is large, the outer shell 34 is in a fixed state. However, the clamping plate 8 does not rigidly clamp the outer conductor 32. Therefore, under the action of the arc-shaped groove 3401 and the inclined rod 37, the outer conductor 32 rotates by a certain angle, and the inclined rod 37 smoothly moves to the position where the arc-shaped groove 3401 is connected to the vertical groove 3402. When the inclined surface of the inclined rod 37 abuts against the inclined step at the connection position, the inclined rod 37 will move towards the inner conductor 33 direction, compress the fourth spring 39, and then smoothly enter the vertical groove 3402. At this time, under the action of the vertical groove 3402 and the inclined rod 37, the outer conductor 32 is in a fixed state. When the outer conductor 32 abuts against the movable disk 35, the movable disk 35 will give way and compress the third spring 36. When the inclined rod 37 moves to the position where the vertical groove 3402 is connected to the annular groove 3403, the clamping plate 20 descends to the maximum depth, the height of the outer shell 34 no longer changes, and under the action of the follow-up rotation assembly, the outer shell 34 is controlled to rotate by a certain angle through the clamping plate 20, so that the inclined rod 37 enters the annular groove 3403. When the outer shell 34 rotates to the maximum angle, the inclined rod 37 moves to the limit hole 3404. At this time, the fourth spring 39 elastically releases and drives the inclined rod 37 to insert into the limit hole 3404. Under the action of the inclined rod 37 and the limit hole 3404, the outer shell 34 and the outer conductor 32 are tightly connected to each other.

[0057] Preferably, after the plugging is completed, during the reset process of the clamping plate 20, since the outer conductor 32 is limited by the clamping plate 8, the outer shell 34 will not move either. Therefore, the clamping plate 20 will provide a pulling force to the outer shell 34 to test whether the outer shell 34 is plugged in place with the outer conductor 32. If the plugging is not in place, the outer shell 34 will move with the clamping plate 20 and separate from the outer conductor 32. Through the connection of plugging and plugging strength testing, the automatic assembly of the connector can be realized, and the effect of quickly verifying the assembly result can be achieved. Among them, if the inclined rod 37 is separated from the limit hole 3404 due to external force, since the third spring 36 still provides a locking force to the outer conductor 32 along the length direction of the outer shell 34, the outer shell 34 will not rotate easily. Therefore, under the double locking of the inclined rod 37 and the third spring 36, the stability of the connector assembly is ensured.
