Description

Technical Field

[0001] This invention relates to the field of radio frequency coaxial connector technology, specifically to an assembly machine, assembly method, and radio frequency coaxial connector applicable to the tin phosphor bronze radio frequency coaxial connector. Background Technology

[0002] Among the components of an RF coaxial connector, the sleeve, body, center pin, solder cup, and tail tube are all made of metal. Beryllium bronze, tin-phosphor bronze, brass, and stainless steel are common precious metal materials used in RF coaxial connectors, each with its own advantages.

[0003] Among them, tin-phosphor bronze has a certain degree of flexibility, making it a substitute for various other copper alloy precious metal materials. Unless beryllium bronze is required for extremely high electrical performance, tin-phosphor bronze can be used as a substitute from other performance perspectives. In terms of the material's inherent properties, tin-phosphor bronze has good corrosion resistance, mechanical properties, and machinability; in terms of usage, tin-phosphor bronze is suitable for larger sockets, flexible contacts, or outer conductors.

[0004] In the mass production process of the industry, when assembling radio frequency coaxial connectors, the assembly equipment usually adopts the plug-in method, and the two plug-in parts are locked together by self-locking.

[0005] In the final quality inspection stage of production, after the connector is plugged in, additional equipment or complex operating procedures are usually required to test the connector plugging strength. It is not possible to test it directly during the assembly process. This may lead to problems with the connector not plugging in firmly in actual application, affecting its overall performance and quality stability. Summary of the Invention

[0020] As a further embodiment of the present invention: the driven component includes a second connecting plate rotatably mounted on the support rod, the second connecting plate having a third sliding groove arranged symmetrically, a third sliding block being slidably mounted in the third sliding groove, and a support column penetrating the second sliding block being provided on the third sliding block;

[0021] It also includes a rotating sleeve slidably mounted on the support rod, a rotating ring rotatably mounted on the rotating sleeve, a first connecting rod hinged to the third sliding block on the rotating ring, and a second connecting rod hinged to the first sliding block on the rotating sleeve.

[0022] As a further embodiment of the present invention: the follower rotation assembly includes a through groove formed on the outer circumference of the hollow rod, a limiting ring passing through the through groove is provided on the support rod, and a first spring and a second spring are sleeved on the hollow rod. The two ends of the first spring abut against the fixing ring and the limiting ring respectively, and the two ends of the second spring abut against the limiting ring and the first connecting plate respectively.

[0023] It also includes a guide groove formed on the support rod, and a limiting block that slides and engages with the guide groove is provided inside the hollow rod.

[0024] An assembly method for a tin-phosphor bronze radio frequency coaxial connector includes the following steps:

[0025] Step 1: The lower clamping assembly controls the card plate to limit the position of some connector components, while the clamping plate clamps the other part of the connector.

[0026] Step 2: Under the action of the lifting component, the upper clamping component controls the clamping plate to move towards the card plate, so as to control the two parts to be inserted into each other;

[0027] Step 3: When the clamping plate moves to the end of its stroke, the lifting component will control the follow-up rotating component to rotate the inserted component by a certain angle through the clamping plate.

[0028] Step 4: After the insertion is completed, the lifting assembly controls the clamping plate to reset, so as to apply a pulling force to the connector. When the pulling force reaches a certain level, the clamping plate is controlled to move in a direction away from each other under the action of the spacing adjustment mechanism.

[0029] A radio frequency coaxial connector, comprising:

[0030] A base, and an outer conductor and an inner conductor mounted on the base, wherein a housing is fitted onto the outer conductor;

[0031] A plug-in locking assembly is disposed on the housing and connected to the outer conductor for fixing the housing to the outer conductor.

[0032] As a further embodiment of the present invention: the plug-in locking assembly includes positioning grooves formed on the inner wall of the housing and distributed circumferentially, a movable disc that abuts against the outer conductor is slidably installed inside the housing, and a third spring that abuts against the movable disc is provided inside the housing;

[0033] It also includes an inclined rod that is slidably mounted on the outer conductor and slidably engaged with the positioning groove, a fixed rod is provided on the inner conductor, and a fourth spring is sleeved on the fixed rod to abut against the inclined rod.

[0034] Compared with the prior art, the beneficial effects of the present invention are: This application can control the fitting component to smoothly insert into the connector after being inserted into the plug-in component via the upper clamping component, and then rotate it by a certain angle to achieve connector assembly. During the clamping plate reset process, a pulling force is simultaneously provided to the fitting component to test the connector insertion strength. Specifically, the lower clamping component controls the clamping plate to limit the plug-in component, and the upper clamping component controls the clamping plate to clamp the fitting component. At this time, under the action of the lifting component, the upper clamping component controls the clamping plate to move towards the clamping plate direction to control the fitting component to be fitted onto the plug-in component. After the clamping plate descends to its maximum depth, under the action of the follow-up rotating component, the clamping plate controls the rotation of the fitting part by a certain angle to complete the insertion. At this time, the lifting component provides a certain pulling force to the fitting part through the upper clamping component and the clamping plate. If the fitting part and the insert are inserted in place, the connector will not separate after insertion. If the fitting part and the insert are not inserted in place, the fitting part will separate from the insert when the clamping plate provides a pulling force to the fitting part. The above operation realizes the assembly of the connector. After the assembly is completed, the insertion and removal quality test of the connector is performed to ensure that the connector is assembled in place.

[0035] After the socket and the connector are plugged in, the clamping plate can provide a pulling force to the socket during the reset phase. This allows the connection strength between the socket and the connector to be tested directly after assembly without the need for additional equipment or complicated procedures. This provides an intuitive way to determine whether the connection is secure and reliable, effectively ensuring the overall performance and quality stability of the connector.

[0036] Through the above series of operational designs and structural coordination, not only is the assembly process guaranteed to proceed smoothly, but the subsequent testing procedures are also greatly simplified, reducing the time and labor costs of the testing process, thereby significantly increasing the overall efficiency of connector assembly.

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0054] Please see Figures 1-14 In this embodiment of the invention, an assembly machine for a tin-phosphor bronze radio frequency coaxial connector includes:

[0055] A processing table 1, and a fixed plate 2 and a support plate 9 fixed on the processing table 1. A conveying assembly is provided on the fixed plate 2. The conveying assembly includes pulleys rotatably mounted on the fixed plate 2 and arranged symmetrically. A conveyor belt 3 is sleeved on the pulleys.

[0056] Also includes:

[0057] A lower clamping assembly is disposed on the processing table 1, and the lower clamping assembly includes symmetrically arranged clamping plates 8;

[0058] A lifting assembly is provided on the support plate 9. An upper clamping assembly is provided on the lifting assembly. The upper clamping assembly includes clamping plates 20 arranged symmetrically. The lifting assembly drives the clamping plates 20 to move in the vertical direction through the upper clamping assembly.

[0059] A spacing adjustment mechanism is disposed on the support plate 9 and connected to the upper clamping assembly. The spacing adjustment mechanism can adjust the spacing between the clamping plates 20 when the upper clamping assembly moves.

[0060] A follow-up rotating component is disposed on the lifting component and connected to the spacing adjustment mechanism. The follow-up rotating component can drive the clamping plate 20 to rotate when the lifting component moves.

[0061] Specifically, the connector assembly can be divided into two parts: the plug and the fitting. The lower clamping assembly controls the clamping plate 8 to limit the plug, while the upper clamping assembly controls the clamping plate 20 to clamp the fitting. At this time, under the action of the lifting assembly, the upper clamping assembly controls the clamping plate 20 to move towards the clamping plate 8, controlling the fitting to fit onto the plug. When the clamping plate 20 descends to its maximum depth, under the action of the follow-up rotation assembly, the clamping plate 20 controls the fitting to rotate at a certain angle to complete the insertion. At this time, the lifting assembly provides a certain pulling force to the fitting through the upper clamping assembly and the clamping plate 20. Because the plug limited by the clamping plate 8 is still in the limited state, the fitting has the potential to move away from the plug. If the connector and the socket are properly inserted, the connector will not separate. After the lifting assembly moves to a certain position, the upper clamping assembly is controlled by the spacing adjustment mechanism to move, so that the two clamping plates 20 move in a direction away from each other to release the socket. If the socket and the connector are not properly inserted, the socket will separate from the connector when the clamping plate 20 provides a pulling force to the socket. At this time, the socket can be clamped by a robot, and the socket can be released after the lifting assembly rises to a certain height. The robot can then transfer the socket. By clamping and limiting the connector and the socket, the connector can be assembled. After assembly, the connector is subjected to insertion and removal quality testing to ensure that the connector is assembled in place.

[0062] Please see Figure 1 , Figure 2 , Figure 5 The lower clamping assembly includes a guide post 4 mounted on the processing table 1, a guide sleeve 5 slidably mounted on the guide post 4, a movable plate 6 mounted on the guide sleeve 5, the movable plate 6 being connected to the clamping plate 8, and a cylinder 7 connected to the movable plate 6 being mounted on the processing table 1.

[0063] In detail, in the initial state, under the action of cylinder 7, the guide sleeve 5 is controlled by movable plate 6 to be located at the end of its stroke away from fixed plate 2, so that the distance between the two clamping plates 8 is maximized. When the plug-in component to be assembled is conveyed by conveyor belt 3 to the position to cooperate with clamping plate 8, cylinder 7 works and controls guide sleeve 5 to move along the length direction of guide post 4 through movable plate 6. Guide sleeve 5 will also drive the two clamping plates 8 to move towards each other until clamping plates 8 limit the bottom of plug-in component and provide a certain clamping force on the side of plug-in component. At this time, plug-in component cannot move in the resin direction, but can rotate freely to facilitate subsequent assembly.

[0064] Please see Figures 1-3 , Figure 7 , Figure 8The lifting assembly includes a guide rail 11 mounted on the support plate 9, a motor 12 mounted on the processing table 1, a lead screw 13 rotatably mounted on the support plate 9 and connected to the output shaft of the motor 12, a threaded sleeve 14 threadedly connected to the lead screw 13 and slidably connected to the guide rail 11, and a fixing ring 15 provided on the side wall of the threaded sleeve 14.

[0065] It should be noted that after the clamping plate 20 clamps the fitting, it is necessary to control the fitting to move toward the insertion part. 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 of the guide rail 11. The guide rail 11 has a guiding function, which can ensure that the threaded sleeve 14 will not rotate with the lead screw 13 when it moves. The threaded sleeve 14 will also drive the fixed ring 15 to move, so as to control the fitting to move toward the insertion part through the upper clamping assembly and the clamping plate 20.

[0066] Please see Figure 1-4 , Figures 6-9 The upper clamping assembly includes a hollow rod 16 mounted on the fixed ring 15, a support rod 17 slidably mounted inside the hollow rod 16, a rotating plate 18 at the end of the support rod 17, a first sliding groove 1801 symmetrically arranged on the rotating plate 18, a first sliding block 19 slidably mounted inside the first sliding groove 1801, and the first sliding block 19 connected to the clamping plate 20. The spacing adjustment mechanism includes guide grooves symmetrically arranged on the support plate 9, a guide rod 10 rotatably mounted inside the guide grooves; it also includes a first connecting plate 21 mounted on the hollow rod 16, a second sliding groove 2101 symmetrically arranged on the first connecting plate 21, a second sliding block 22 slidably mounted inside the second sliding groove 2101, and a second sliding block 22 provided with... The limiting post 23 is slidably fitted with the guide groove. The support rod 17 is provided with a driven component connected to the second sliding block 22. The driven component includes a second connecting plate 24 rotatably mounted on the support rod 17. The second connecting plate 24 has a third sliding groove 2401 symmetrically arranged. A third sliding block 25 is slidably mounted in the third sliding groove 2401. A support post 26 penetrating the second sliding block 22 is provided on the third sliding block 25. The component also includes a rotating sleeve 27 slidably mounted on the support rod 17. A rotating ring 2701 is rotatably mounted on the rotating sleeve 27. A first connecting rod 28 hinged to the third sliding block 25 is hinged to the rotating ring 2701. A second connecting rod 29 hinged to the first sliding block 19 is hinged to the rotating sleeve 27.

[0067] Furthermore, the guide groove can be divided into five sections: 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. The two ends of the second inclined groove 904 are connected to the ends of the first vertical groove 901 and the second vertical groove 903, respectively. The limiting groove 905 is located at the connection position between the first inclined groove 902 and the first vertical groove 901. The guide rod 10 is located in the limiting groove 905, and 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.

[0068] 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, so that the distance between the two second sliding blocks 22 is minimized, so that the distance between the two third sliding blocks 25 is minimized by the support post 26. The third sliding block 25 will control the rotating sleeve 27 to be located at the end of the stroke in the direction of the rotating plate 18 by the first connecting rod 28 and the rotating ring 2701, so that the distance between the two first sliding blocks 19 and the clamping plate 20 is maximized by the second connecting rod 29.

[0069] Subsequently, the assembly components can be transported to the highest point that the clamping plate 20 can rise to using a robotic arm. Simultaneously, 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 rotating assembly, the support rod 17 moves synchronously, thereby driving the rotating plate 18 to move, controlling the clamping plate 20 to rise. The hollow rod 16 also drives the first connecting plate 21 to move, thereby driving the limiting post 23 to move along the length direction of the second vertical groove 903 via the second sliding block 22. When the limiting post 23 disengages from the second vertical groove 903 and enters the second inclined groove 904, the two second sliding blocks... Block 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 position where the second inclined groove 904 and the first vertical groove 901 are connected, the clamping plate 20 rises to the position to cooperate with the robot arm, the motor 12 stops working, the distance between the clamping plates 20 reaches the minimum, and the fitting is clamped, and the robot arm can be withdrawn.

[0070] At this time, the motor 12 controls the lead screw 13 to reverse, so as to control the hollow rod 16 to move towards the fixed plate 2. Under the action of the follower rotating assembly, the support rod 17 is controlled to move synchronously with the hollow rod 16, and drives the first sliding block 19 to move through the rotating plate 18, thereby driving the sleeve to move through the clamping plate 20. At the same time, the limiting post 23 will slide along the first vertical groove 901 to ensure that the distance between the clamping plates 20 remains unchanged. When the limiting post 23 abuts against the guide rod 10, the guide rod 10 will give way and block the first inclined groove 902. The limiting post 23 will continue to slide along the first vertical groove 901. Under the action of the torsion spring, the guide rod 10 will be reset. When the depth of the fitting into the plug-in reaches the maximum, the position of the clamping plate 20 and the support rod 17 will no longer change. The lead screw 13 will continue to rotate, which will increase the size of the fitting between the hollow rod 16 and the support rod 17. Under the action of the follow-up rotating assembly, the support rod 17 will rotate, thereby driving the rotating plate 18 to rotate. Under the action of the rotating plate 18, the fitting will be rotated by the clamping plate 20, so that the fitting and the plug-in can be inserted into each other.

[0071] After insertion, the lifting assembly controls the hollow rod 16 to move away from the fixed plate 2. If the insertion part and the fitting part are firmly inserted, under the action of the follow-up rotation assembly, the support rod 17 will not follow the hollow rod 16 and will provide a force to the fitting part to move away from the insertion part through the clamping plate 20 to test the insertion strength. The limiting 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 limiting post 23 moves to the position of abutting against the guide rod 10, the first vertical groove 901 is blocked. The limiting post 23 will enter the first inclined groove 902, causing the clamping plate 20 to move in a direction away from each other and release the fitting. At this time, the insertion strength test of the connector assembly is completed. If the insertion of the fitting is loose, the support rod 17 will follow the hollow rod 16 under the action of the follow-up rotating component, so as to drive the fitting to detach from the fitting through the clamping plate 20. The robot can move to the gripping position. When the limiting post 23 detaches from the first vertical groove 901 and enters the first inclined groove 902, the fitting is released and the robot can grip the released fitting.

[0072] Preferably, the precise cooperation between the limiting post 23 and the guide groove ensures that the spacing between the clamping plates 20 remains constant throughout the entire descent stroke of the clamping plates 20, without any change. This feature is crucial for the smooth assembly of the connector, effectively avoiding assembly errors or failures caused by variations in the spacing of the clamping plates 20, and significantly improving the accuracy and reliability of the assembly.

[0073] Meanwhile, after the ferrule and connector are fully inserted, this structural design provides a stable tensile force to the ferrule during the reset phase of the clamping plate 20. This tensile force allows for direct testing of the insertion strength between the ferrule and connector after assembly, without the need for additional equipment or complex procedures. This provides a clear and intuitive assessment of the secure and reliable connection, effectively ensuring the overall performance and quality stability of the connector.

[0074] Through the above series of operational designs and structural coordination, not only is the assembly process guaranteed to proceed smoothly, but the subsequent testing procedures are also greatly simplified, reducing the time and labor costs of the testing process, thereby significantly increasing the overall efficiency of connector assembly.

[0075] Please see Figures 1-3 , Figures 7-10 The follower rotation assembly includes a through groove 1601 formed on the outer circumference of the hollow rod 16, a limiting ring 1705 passing through the through groove 1601 on the support rod 17, a first spring 30 and a second spring 31 sleeved on the hollow rod 16, the two ends of the first spring 30 abutting against the fixed ring 15 and the limiting ring 1705 respectively, and the two ends of the second spring 31 abutting against the limiting ring 1705 and the first connecting plate 21 respectively; it also includes a guide groove formed on the support rod 17, and a limiting block 1602 slidably fitted into the guide groove in the hollow rod 16.

[0076] Furthermore, the guide groove can be divided into four sections: a first straight groove 1701, a first spiral groove 1702, a second straight groove 1703, and a second spiral groove 1704. The two ends of the first spiral groove 1702 are connected to the ends of the first straight groove 1701 and the second straight groove 1703, respectively. 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. Initially, 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, ensuring that the dimensions of the support rod 17 and the hollow rod 16 remain unchanged when they are fitted together. The limiting block 1602 is located within the first straight groove 1701 and within the second spiral groove 1704. Above 04, under the action of the first spring 30 and the second spring 31, the hollow rod 16 moves toward the fixed plate 2, and the support rod 17 moves synchronously with the hollow rod 16. When the fitting is completely inserted into the plug, 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, causing the first spring 30 to be compressed and the second spring 31 to be released elastically. At the same time, the control limit block 1602 slides along the first straight groove 1701. When the limit 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 at a certain angle to ensure that the fitting and the plug are assembled smoothly.

[0077] After assembly, under the action of the lifting assembly, the hollow rod 16 moves toward the initial position. At this time, the first spring 30 is released elastically, the second spring 31 is compressed, the position of the support rod 17 remains unchanged, and the limiting block 1602 moves along the second straight groove 1703. If the fitting and the plug 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 toward the initial angle and controls the fitting and the plug to rotate synchronously through the clamping plate 20 until the limiting block 1602 returns to the first straight groove 1701. The force on the limiting ring 1705 is balanced again, and the lifting assembly continues to move to provide the fitting with a pulling force through the clamping plate 20, thereby testing the insertion strength of the connector. If the fitting and the plug 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.

[0078] Preferably, by cooperating with the limiting block 1602 and the guide groove, the fitting can be rotated at a certain angle when it is fully inserted into the connector, so as to ensure that the fitting can be smoothly assembled with the connector.

[0079] An assembly method for a tin-phosphor bronze radio frequency coaxial connector includes the following steps:

[0080] Step 1: The lower clamping assembly controls the card plate 8 to limit the position of some connector components, while the clamping plate 20 clamps the other part of the connector components.

[0081] Step 2: Under the action of the lifting component, the clamping plate 20 is controlled to move towards the card plate 8 by the upper clamping component, so as to control the two parts to be inserted into each other.

[0082] Step 3: When the clamping plate 20 moves to the end of its stroke, the lifting component will control the follow-up rotating component to move, so as to control the inserted component to rotate a certain angle through the clamping plate 20.

[0083] Step 4: After the insertion is completed, the lifting assembly controls the clamping plate 20 to reset, so as to apply a pulling force to the connector. When the pulling force reaches a certain level, the clamping plate 20 is controlled to move in a direction away from each other under the action of the spacing adjustment mechanism.

[0084] A radio frequency coaxial connector, comprising:

[0085] A base 3201, and an outer conductor 32 and an inner conductor 33 mounted on the base 3201, wherein a housing 34 is fitted onto the outer conductor 32;

[0086] Please see Figures 11-14 A plug-in locking assembly is disposed on the outer shell 34 and connected to the outer conductor 32 for fixing the outer shell 34 to the outer conductor 32. The plug-in locking assembly includes positioning grooves formed on the inner wall of the outer shell 34 and distributed circumferentially. A movable disk 35 that abuts against the outer conductor 32 is slidably installed inside the outer shell 34. A third spring 36 that abuts against the movable disk 35 is disposed inside the outer shell 34.

[0087] It also includes an inclined rod 37 that is slidably mounted on the outer conductor 32 and slidably engaged with the positioning groove, and a fixed rod 38 is provided on the inner conductor 33. A fourth spring 39 is sleeved on the fixed rod 38 and abuts against the inclined rod 37.

[0088] The positioning groove can be divided into multiple sections, namely an arc groove 3401, a first vertical groove 3402, an annular groove 3403, and a limiting hole 3405. The arc groove 3401 is formed at the end of the outer shell 34. The most concave position of the arc groove 3401 is connected to one end of the first vertical groove 3402. The other end of the first vertical groove 3402 is connected to one end of the annular groove 3403. The limiting hole 3405 is located at the other end of the annular groove 3403 and penetrates the outer shell 34. The connection position between the arc groove 3401 and the first vertical groove 3402 is set 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 its stroke facing the arc groove 3401. The inclined rod 37 is provided with a follower ring 3701 that abuts against the inner wall of the outer conductor 32. The fourth spring 39 is also in a compressed state, so that the inclined rod 37 is located at the end of its stroke away from the inner conductor 33, and the end of the inclined rod 37 is set in an inclined shape.

[0089] In this application, the outer shell 34 is the aforementioned fitting, and the inner conductor 33, outer conductor 32, and base 3201 are combined to form a connector. Therefore, when assembling the connector, the base 3201 can be placed on the conveyor belt 3 and moved to a position that mates 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 groove 3401 face the direction of the conveyor belt 3. When the outer casing 34 is fitted onto the outer conductor 32, the arc-shaped groove 3401 will first abut against the tilting rod 37. Due to the large clamping force on the outer casing 34, the outer casing 34 is in a fixed state, while the clamping plate 8 does not rigidly clamp the outer conductor 32. Therefore, under the action of the arc-shaped groove 3401 and the tilting rod 37, the outer conductor 32 rotates at a certain angle, and the tilting rod 37 moves smoothly to the position where the arc-shaped groove 3401 connects with the first vertical groove 3402. The inclined surface of the tilting rod 37 and the inclined step at the connection position... Upon contact, the tilting rod 37 will move towards the inner conductor 33 and compress the fourth spring 39, smoothly entering the first vertical groove 3402. At this time, under the action of the first vertical groove 3402 and the tilting rod 37, the outer conductor 32 is fixed. When the outer conductor 32 contacts the movable plate 35, the movable plate 35 will move aside and compress the third spring 36. When the tilting rod 37 moves to the position where the first vertical groove 3402 connects with the annular groove 3403, the clamping plate 20 descends to its lowest position. With a large depth, the height of the outer shell 34 no longer changes. Under the action of the follow-up rotating component, the clamping plate 20 controls the outer shell 34 to rotate at a certain angle, so that the tilting rod 37 enters the annular groove 3403. When the outer shell 34 rotates to the maximum angle, the tilting rod 37 moves to the limiting hole 3405. At this time, the fourth spring 39 is released elastically and drives the tilting rod 37 to insert into the limiting hole 3405. Under the action of the tilting rod 37 and the limiting hole 3405, the outer shell 34 and the outer conductor 32 are tightly connected to each other.

[0090] Preferably, after insertion, during the reset process of the clamping plate 20, the outer conductor 32 is limited by the clamping plate 8, so the outer shell 34 will not move. Therefore, the clamping plate 20 will provide a pulling force to the outer shell 34 to test whether the outer shell 34 is inserted into the outer conductor 32. If the insertion is not in place, the outer shell 34 will move with the clamping plate 20 and disengage from the outer conductor 32. Through the connection of insertion and insertion strength test, the automatic assembly of the connector can be achieved and the assembly result can be quickly verified. If the tilting rod 37 disengages from the limiting hole 3405 due to external force, the third spring 36 also provides a locking force to the outer conductor 32 along the length of the outer shell 34, so the outer shell 34 will not easily rotate. Thus, the stability of the connector assembly is ensured by the double locking of the tilting rod 37 and the third spring 36.
