Description

Technical Field

[0001] This invention relates to the field of connector technology, specifically to a male connector based on thread intermodulation testing, an assembly fixture, and an assembly method. Background Technology

[0002] In fields such as communication equipment and electronic testing, threaded connectors are widely used in intermodulation testing and other scenarios due to their stable connection and good sealing performance. Their core function is to achieve a reliable electrical connection between the test equipment and the device under test, and to ensure the stable transmission of test signals.

[0003] Currently, the connection method of existing male connectors and adapter sockets for intermodulation testing generally adopts the traditional threaded rigid connection structure. In the single state, the connector plug and socket are independent and separate components. The two are connected by thread engagement to carry out electrical performance tests such as intermodulation, standing wave, and attenuation.

[0004] However, existing technical solutions have significant drawbacks: during the meshing test, if the socket or plug end is subjected to an unavoidable external force, it is prone to deformation due to axial overload and eccentric overload. Since the threaded rigid connection lacks buffering and self-adjustment capabilities, the stress caused by this external force will continue to act on the threaded structure and end face contact parts of the connector, and cannot be effectively released. In the long run, this will lead to increased thread wear and decreased end face contact accuracy, directly affecting the electrical performance stability of the connector and causing fluctuations in test data. Therefore, in order to address the above problems, a male connector, assembly fixture, and assembly method based on thread intermodulation testing are proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a male connector based on thread intermodulation testing, an assembly fixture, and an assembly method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A threaded interoperability test male connector includes a socket assembly and a plug assembly. A support and buffer assembly is mounted on the outer side of the plug assembly. The plug assembly includes a plug shell with an annular groove on its outer side. A sleeve shell is fixedly connected to the outer side of the plug shell near its front end. An extension plate is fixedly connected to the rear end of the sleeve shell, and an arc-shaped surface is formed on the periphery of the extension plate. The support and buffer assembly includes a support shell with a spring groove on its inner side and an anti-disengagement groove on its outer side. A linear spring is fixedly connected to the rear end of the support shell through the spring groove. A chamfered surface is formed near the rear end of the support shell. A 2mm gap is provided between the inner side of the rear end of the support shell and the outer side of the plug shell. The inner side of the support shell fits against the outer periphery of the arc-shaped surface of the extension plate. The front end of the linear spring is fixedly connected to the rear end of the extension plate.

[0008] As a further optimization of the present invention, the socket assembly includes a socket body, an annular groove is formed on the outer side of the socket body, a clip is engaged inside the annular groove, and the clip is fixedly connected to the front end of the housing.

[0009] As a further optimization of the present invention, a pin is inserted into the inner side of the socket body, and a connecting wire is fixedly connected to the rear end of the pin, and the connecting wire is fixedly connected to the inner side of the plug shell.

[0010] As a further optimization of the present invention, the chamfered surface is located inside the annular groove, and a gap is provided between the rear end of the support shell and the rear end of the annular groove.

[0011] An assembly fixture includes a fixing component mounted on the upper end of a drive component, wherein a torsion test component is mounted on one end of the drive component.

[0012] As a further optimization of the present invention, the fixing component includes a base, a sliding hole is provided on the inner side of the base, a first arc-shaped clamping plate is fixedly connected to the top of the base, a sliding column and a baffle are fixedly connected in sequence to the right side of the first arc-shaped clamping plate, a compression spring is fixedly connected to the left side of the baffle, a second arc-shaped clamping plate is slidably connected to the outer side of the sliding column, the left end of the compression spring is fixedly connected to the second arc-shaped clamping plate, and a handle is fixedly connected to the top of the second arc-shaped clamping plate.

[0013] As a further optimization of the present invention, the driving component includes a machine base, a vertical plate is fixedly connected to the top of the machine base, a servo motor is fixedly connected to one side of the vertical plate, a servo electric cylinder and a rail column are fixedly connected to the other side of the vertical plate, the piston rod end of the servo electric cylinder is fixedly connected to the rear end of the base, and the inner side of the rail column is slidably engaged with the outer side of the sliding hole.

[0014] As a further optimization of the present invention, the servo motor spindle is fixedly connected to a rotating plate included in the torsion testing component. The upper end of the rotating plate is provided with a first arc-shaped pressure groove, and the top of the rotating plate is fixedly connected with an ear seat. The inner side of the ear seat is provided with a screw hole.

[0015] As a further optimization of the present invention, a screw is threadedly connected to the inner side of the screw hole, an arch plate is fixedly connected to the lug via the screw, the screw is inserted into the through-hole of the arch plate, and a second arc-shaped pressure groove is provided on the inner side of the arch plate.

[0016] Male connectors, assembly fixtures, and assembly methods based on thread interoperability testing;

[0017] Step 1: During assembly, first install the support and buffer assembly and the fixing assembly. Push the handle, which moves the second arc-shaped clamp away from the first arc-shaped clamp. The second arc-shaped clamp slides on the outside of the slide column and compresses the compression spring. At this time, an installation gap is formed between the second arc-shaped clamp and the first arc-shaped clamp. Place the spring groove of the support shell into the gap between the second arc-shaped clamp and the first arc-shaped clamp. Release the handle, and the compression spring elastically pushes the second arc-shaped clamp back to its original position. The support shell is clamped by the cooperation of the first arc-shaped clamp and the second arc-shaped clamp. At this time, both the first arc-shaped clamp and the second arc-shaped clamp are located inside the spring groove. Then connect the socket body and the plug assembly. Align the socket body's socket hole with the pin front and back. Push the socket body backward. During the pushing process, the plug shell moves. After the linear spring is compressed to its limit, the pin is inserted into the socket body. The locking head deforms after contacting the socket body until it is aligned with the ring groove. Then the locking head returns to its original shape and locks into the ring groove, completing the installation.

[0018] Step 2: During the meshing test, the connecting wire is placed inside the first arc-shaped groove, and the second arc-shaped groove of the arch plate is fitted onto the upper end of the connecting wire. At the same time, the through-hole and the screw hole are aligned vertically. The screw is inserted into the through-hole, and the screw is rotated to connect the thread to the screw hole. The large end of the screw presses down on the arch plate, so that the arch plate and the rotating plate cooperate to fix the connecting wire. The servo cylinder is started to push the fixing assembly forward. The first arc-shaped clamping plate and the second arc-shaped clamping plate push the support shell forward. The connecting wire remains fixed. The support shell pushes and compresses the linear spring. The linear spring undergoes elastic deformation. The inner side of the support shell slides on the outer side of the plug shell, completing the axial overload test. The servo motor is started to drive the rotating plate to rotate. The rotating plate and the arch plate clamp the connecting wire, which in turn causes the connecting wire to twist. The twisting of the connecting wire causes the plug shell to twist. The position of the rear end of the support shell inside the annular groove changes. The arc-shaped surface and the chamfered surface provide space for the twisting of the plug shell inside the support shell.

[0019] Step 3: A helical spring is placed between the support shell and the plug shell as an elastic support component, forming an elastic adaptive buffer mechanism. When the connector engagement test is subjected to axial or eccentric overload by external force, the linear spring absorbs the overload energy through compression, tension, or deformation, adjusting the relative position of the plug shell and the support shell to ensure the coaxial alignment of the plug assembly and the socket assembly. The elasticity of the helical spring line itself provides the front engagement pressure between the plug assembly and the socket assembly. After the test, the connection between the connecting line and the torsion test assembly is removed, and the helical spring drives the plug shell and the support shell back to their original coaxial position by virtue of its rebound coefficient. A double-layer nested structure in which the support shell and the plug shell are interlocked is adopted, which can replace the traditional single rigid shell in either the connector socket assembly or the plug assembly.

[0020] Step 4: Adopt a double-layer nested structure in which the support shell and the plug shell are interlocked. Replace the traditional single rigid shell with either the connector socket assembly or the plug assembly. Combine the inner mold injection molding and outer mold injection molding processes to complete the assembly of the plug shell, support shell and helical spring structure.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In this invention, the device can quickly complete the positioning and docking of various components by setting the first arc-shaped clamp, the second arc-shaped clamp, the compression spring and the clamp head. The operation process is simple and easy to understand, which greatly improves the assembly efficiency. At the same time, this assembly method can directly provide the basic conditions for subsequent installation quality inspection, without the need for repeated disassembly and assembly during the later inspection, which significantly reduces the workload and time cost of the inspection process and avoids the additional damage to the components caused by repeated operations.

[0023] 2. In this invention, by setting up a servo motor, servo cylinder, rotating plate, screw and arch plate, the device can flexibly and accurately control the test frequency and intensity, and efficiently achieve full coverage of the two core test scenarios of axial overload and torsion. There is no need for complicated and tedious pre-debugging and mid-term calibration steps, which significantly reduces the skill threshold and operation difficulty of operators, greatly shortens the overall time of a single test, and improves the efficiency of test work.

[0024] 3. In this invention, the linear spring, plug shell, and support shell solve the two failure states of axial overload and eccentric overload during connector use and testing. It absorbs overload energy, offsets external impact, and avoids stress acting directly on the thread structure and end face contact parts, ensuring coaxial alignment of the test components. It abandons the traditional mode of determining the meshing pressure by the thread connection torque, and relies on the spring force to provide uniform and stable front meshing pressure, which is not affected by external operating force. It achieves high repeatability of electrical test performance such as standing wave, intermodulation, and attenuation, effectively avoids thread wear and end face overload damage, reduces the risk of product failure, significantly increases the number of times the connector can be reused, and extends its service life.

[0041] 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.

[0042] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0043] Please see Figures 1-10 The present invention provides a technical solution:

[0044] The threaded interoperability test male connector includes a socket assembly 1 and a plug assembly 2. A support and buffer assembly 3 is installed on the outside of the plug assembly 2. The plug assembly 2 includes a plug shell 21 with an annular groove 24 on its outer side. A sleeve shell 25 is fixedly connected to the outer side of the plug shell 21 near the front end. An extension plate 27 is fixedly connected to the rear end of the sleeve shell 25. An arc-shaped surface 28 is formed on the periphery of the extension plate 27. The support and buffer assembly 3 includes a support shell 31 with a spring groove 32 on its inner side and an anti-disengagement groove 33 on its outer side. A linear spring 34 is fixedly connected to the rear end of the support shell 31 through the spring groove 32. A chamfered surface 35 is formed near the rear end of the support shell 31. A 2mm gap is provided between the inner side of the rear end of the support shell 31 and the outer side of the plug shell 21. The inner side of the support shell 31 fits against the periphery of the arc-shaped surface 28 of the extension plate 27. The front end of the linear spring 34 is fixedly connected to the rear end of the extension plate 27.

[0045] As a further implementation of this solution, the socket assembly 1 includes a socket body 11. An annular groove 12 is provided on the outer side of the socket body 11, and a snap-fit ​​head 26 is engaged on the inner side of the annular groove 12. The snap-fit ​​head 26 is fixedly connected to the front end of the housing 25. Through the above configuration, the socket body 11 serves as the core main structure of the socket assembly 1, providing a stable carrier for component connection. The snap-fit ​​engagement of the annular groove 12 and the snap-fit ​​head 26 enables quick positioning and docking of the socket body 11 and the housing 25 without the need for complex operations such as threading, greatly improving assembly efficiency. The snap-fit ​​structure has a good limiting effect, which can effectively prevent relative displacement between the socket body 11 and the housing 25, ensuring connection stability. At the same time, the elastic deformation characteristics of the snap-fit ​​head 26 can adapt to slight deviations during the assembly process, reducing assembly accuracy requirements and avoiding component damage caused by rigid docking.

[0046] As a further implementation of this solution, a pin 23 is inserted into the inner side of the socket body 11, and a connecting wire 22 is fixedly connected to the rear end of the pin 23. The connecting wire 22 is fixedly connected to the inner side of the plug shell 21. Through the above arrangement, the insertion and cooperation between the pin 23 and the socket body 11 realizes the quick electrical and mechanical connection between the socket assembly 1 and the plug shell 21 assembly. The assembly is convenient and the disassembly is flexible, which facilitates later maintenance and repair. The connecting wire 22 fixes the pin 23 and the plug shell 21 into one piece, ensuring the rigidity of the connection between the components and avoiding signal transmission interruption or test data distortion caused by component loosening during the test. The overall structure realizes the synchronous transmission of power and signal, providing a stable structural foundation for axial overload and torsion tests, and improving the continuity and reliability of the test process.

[0047] As a further implementation of this solution, the chamfered surface 35 is located inside the annular groove 24, and a gap is provided between the rear end of the support shell 31 and the rear end of the annular groove 24. Through the above-mentioned arrangement, the design of the chamfered surface 35 being located inside the annular groove 24 provides sufficient space for the torsional movement of the plug shell 21, avoiding interference between the plug shell 21 and the annular groove 24 when torturing, and ensuring the smooth conduct of the torsion test. The gap between the rear end of the support shell 31 and the rear end of the annular groove 24 provides buffer space for the axial displacement of the support shell 31, adapting to the position adjustment requirements brought about by the elastic deformation of the linear spring 34. At the same time, it can avoid hard collision between the support shell 31 and the annular groove 24 during the axial overload test, reduce component wear, extend product service life, and further ensure the safety and stability of the test process.

[0048] An assembly fixture includes a fixing component 4, which is mounted on the upper end of a drive component 5, and a torsion test component 6 is mounted on one end of the drive component 5.

[0049] As a further implementation of this solution, the fixing component 4 includes a base 41. A sliding hole 42 is provided on the inner side of the base 41. A first arc-shaped clamping plate 43 is fixedly connected to the top of the base 41. A sliding column 44 and a baffle 48 are sequentially fixedly connected to the right side of the first arc-shaped clamping plate 43. A compression spring 45 is fixedly connected to the left side of the baffle 48. A second arc-shaped clamping plate 46 is slidably connected to the outer side of the sliding column 44. The left end of the compression spring 45 is fixedly connected to the second arc-shaped clamping plate 46. A handle 47 is fixedly connected to the top of the second arc-shaped clamping plate 46. Through the above arrangement, the base 41 serves as the main load-bearing structure of the fixing component 4, supporting the first arc-shaped clamping plate 43 and the sliding column 44. The components provide a stable installation base. By pushing the handle 47, the second arc-shaped clamp 46 can be slid along the outside of the slide column 44. With the elastic reset action of the compression spring 45, the distance between the second arc-shaped clamp 46 and the first arc-shaped clamp 43 can be quickly adjusted and locked, thereby completing the quick clamping and positioning of the support shell 31. No additional tooling is required, which simplifies the assembly operation steps and improves the convenience and efficiency of component assembly. At the same time, the way the first arc-shaped clamp 43 and the second arc-shaped clamp 46 are embedded in the spring groove 32 can effectively limit the front and rear displacement of the support shell 31 and ensure the connection stability of the components after assembly.

[0050] As a further implementation of this solution, the drive component 5 includes a machine base 51. A vertical plate 52 is fixedly connected to the top of the machine base 51. A servo motor 53 is fixedly connected to one side of the vertical plate 52, and a servo electric cylinder 54 and a rail column 55 are fixedly connected to the other side of the vertical plate 52. The piston rod end of the servo electric cylinder 54 is fixedly connected to the rear end of the base 41. The inner side of the rail column 55 slides with the outer side of the sliding hole 42. Through the above settings, the machine base 51 provides stable support for the vertical plate 52 and each drive component. The servo electric cylinder 54 can accurately push the fixed component 4 to make linear displacement, providing stable power output for axial overload testing. The sliding fit structure between the rail column 55 and the sliding hole 42 can guide and limit the movement direction of the fixed component 4, preventing it from deviating during displacement and ensuring the accuracy of the test process. The servo motor 53 can output stable rotational driving force, providing power support for torsional testing. The overall structure integrates axial and torsional drive functions, and can achieve coverage of two core test scenarios without changing the test device, greatly improving the integration and efficiency of the test work.

[0051] As a further implementation of this solution, the spindle end of the servo motor 53 is fixedly connected to a rotating plate 61, which is part of the torsion test assembly 6. The upper end of the rotating plate 61 is provided with a first arc-shaped pressure groove 62, and the top of the rotating plate 61 is fixedly connected with an ear seat 63. The inner side of the ear seat 63 is provided with a screw hole 64. With the above configuration, the rotating plate 61 serves as the bearing and fixing base for the connecting line 22. The first arc-shaped pressure groove 62 can pre-position the connecting line 22 to prevent the connecting line 22 from shifting laterally during the test. The structural design of the ear seat 63 and the screw hole 64 provides a suitable space for the installation and locking of the screw 65. The screw 65 can be threaded to lock the arch plate 66, thereby completing the firm fixing of the connecting line 22, ensuring the positional stability of the connecting line 22 during the test, avoiding test data deviation caused by component loosening, and improving the accuracy and reliability of the test results.

[0052] As a further implementation of this solution, a screw 65 is threadedly connected to the inner side of the screw hole 64. An arch plate 66 is fixedly connected to the lug 63 via the screw 65. The screw 65 is inserted into the through-hole 67 of the arch plate 66. A second arc-shaped pressure groove 68 is provided on the inner side of the arch plate 66. Through the above configuration, the threaded connection structure between the screw 65 and the screw hole 64 can achieve uniform downward pressure on the arch plate 66 through rotation. Combined with the support of the rotating plate 61, it can achieve bidirectional clamping of the connecting wire 22. The fixing force can be precisely adjusted by the rotation stroke to adapt to the fixing requirements of connecting wires 22 of different specifications. The way the screw 65 is inserted into the through-hole 67 can prevent the arch plate 66 from rotating circumferentially during the locking process, ensuring the stability of the clamping. The overall locking structure is simple to operate and can quickly fix and disassemble the connecting wire 22 without professional tools, reducing the skill threshold for operators and shortening the test preparation time.

[0053] Workflow: During assembly, first, install the support buffer assembly 3 and the fixing assembly 4. Push and pull the handle 47, which moves the second arc-shaped clamping plate 46 away from the first arc-shaped clamping plate 43. The second arc-shaped clamping plate 46 slides on the outside of the slide column 44, and the second arc-shaped clamping plate 46 compresses the compression spring 45. At this time, there is an installation gap between the second arc-shaped clamping plate 46 and the first arc-shaped clamping plate 43. The spring groove 32 opened in the support shell 31 is positioned to fill the gap between the second arc-shaped clamping plate 46 and the first arc-shaped clamping plate 43. Then, release the handle 47. The elastic pushing action of the compression spring 45 resets the second arc-shaped clamping plate 46. Through the cooperation of the first arc-shaped clamping plate 43 and the second arc-shaped clamping plate 46, the support shell 31 is clamped. At this time, both the first arc-shaped clamping plate 43 and the second arc-shaped clamping plate 46 are located in the spring groove 32. Inside, the opening of the spring groove 32 can prevent the fixed support shell 31 from moving back and forth. At this time, when connecting the socket body 11 and the plug assembly 2, the socket hole of the socket body 11 and the pin 23 are aligned front and back. By pushing the socket body 11 to move backward, although the pushing of the socket body 11 will cause the plug shell 21 to move, after the linear spring 34 is compressed to the limit, the pin 23 will be inserted into the socket body 11. At the same time, after the locking head 26 contacts the socket body 11, the locking head 26 will deform until it is aligned with the annular groove 12. Then the locking head 26 will return to its original shape and lock into the annular groove 12, thus achieving the installation effect. This assembly method can quickly position the device and is easy to operate. At the same time, this installation method provides a basis for quality inspection after installation, and there is no need to reinstall during subsequent inspection.

[0054] During the meshing test, the connecting wire 22 is placed inside the first arc-shaped groove 62, and the second arc-shaped groove 68 of the arch plate 66 is fitted onto the upper end of the connecting wire 22. At the same time, the through-hole 67 is aligned vertically with the screw hole 64. The screw 65 is inserted into the through-hole 67, and by rotating the screw 65, the screw 65 is threaded into the screw hole 64. The large end of the upper end of the screw 65 presses down on the arch plate 66, so that the arch plate 66 and the rotating plate 61 fix the connecting wire 22. The servo cylinder 54 is activated to push the fixing assembly 4 forward. The first arc-shaped clamping plate 43 and the second arc-shaped clamping plate 46 push the support shell 31 forward. Since the connecting wire 22 is fixed, the push of the support shell 31 will be aligned with a straight line. When spring 34 is compressed, linear spring 34 undergoes elastic deformation, and the inner side of support shell 31 slides on the outer side of plug shell 21 to achieve axial overload test. When servo motor 53 is started, it will drive rotating plate 61 to rotate. When rotating plate 61 rotates, the connecting line 22 will be clamped by rotating plate 61 and arch plate 66, which will cause the connecting line 22 to twist. When the connecting line 22 twists, it will cause plug shell 21 to twist. At this time, the rear end of support shell 31 will not change position inside the annular groove 24. The opening of arc surface 28 and chamfer surface 35 provides space for the twisting of plug shell 21 inside support shell 31. This test method is convenient and easy to use, and can accurately control the test frequency and intensity, significantly simulating real use conditions.

[0055] A helical spring 34, acting as an elastic support component, is positioned between the support shell 31 and the plug shell 21. Utilizing the elastic properties of the linear spring 34, an elastic adaptive buffer mechanism is formed. When the connector experiences axial or eccentric overloads during the engagement test, the linear spring 34 absorbs the overload energy through compression, tension, or deformation, offsetting the impact of the external force and preventing stress from directly acting on the threaded structure and end-face contact area. Simultaneously, it adjusts the relative position of the plug shell 21 and the support shell 31 in real time, ensuring the coaxial alignment of the plug assembly 2 and the socket assembly 1. This also abandons the traditional mode where the engagement pressure is determined by the threaded connection torque, instead using a helical spring... The elastic force of the spiral spring wire provides the front engagement pressure between the plug assembly 2 and the socket assembly 1. This elastic force is not affected by the difference in external operating force, ensuring that the front pressure of each engagement is uniform and consistent, thereby achieving high repeatability of electrical test performance such as standing wave, intermodulation, and attenuation. After the test, the connecting wire 22 is removed from the torsion test assembly 6. The spiral spring 34, with its own rebound coefficient, drives the plug shell 21 and the support shell 31 back to their original coaxial position, completing the structural reset. This design effectively avoids thread wear and end face overload damage, reduces the risk of product failure, greatly increases the number of times the connector can be reused, and extends its service life.

[0056] The nested housing plug shell 21 and support shell 31, combined with the elastic support mechanism of linear spring 34 and integrated injection molding process, solve the overload failure problem of traditional threaded connectors, while ensuring consistent test performance and product durability. Specifically, the overall structure adopts a double-layer nested structure in which the support shell 31 and plug shell 21 are interlocked. Either the connector socket assembly 1 or the plug assembly 2 replaces the traditional single rigid shell, providing a structural basis for overload buffering. The double-layer structure provides space for displacement adjustment. Combined with a new process that combines inner mold injection and outer mold injection, the assembly accuracy and structural integrity of the plug shell 21, support shell 31 and helical spring 34 are ensured, avoiding component loosening or displacement. This simplifies the production process, enables efficient mass production, and provides process assurance for the stable realization of the overall principle.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

At this time, the first arc-shaped clamp (43) and the second arc-shaped clamp (46) are both located inside the spring groove (32). Then, the socket body (11) is connected to the plug assembly (2). The socket hole of the socket body (11) is aligned with the pin (23) front and back. The socket body (11) is pushed to move backward. During the pushing process, the plug shell (21) is moved. After the linear spring (34) is compressed to the limit, the pin (23) is inserted into the socket body (11). The clip (26) deforms after contacting the socket body (11) until the clip (26) is aligned with the annular groove (12). Then the clip (26) returns to its original shape and is inserted into the annular groove (12), completing the installation. Step 2: During the meshing test, place the connecting wire (22) inside the first arc-shaped groove (62), and the second arc-shaped groove (68) of the arch plate (66) is fitted onto the upper end of the connecting wire (22). At the same time, the through-hole (67) is aligned vertically with the screw hole (64). Insert the screw (65) into the through-hole (67), rotate the screw (65) to make its thread connect to the screw hole (64), and press down on the arch plate (66) through the large end of the upper end of the screw (65) so that the arch plate (66) and the rotating plate (61) cooperate to fix the connecting wire (22). Start the servo electric cylinder (54) to push the fixing assembly (4) forward as a whole, and push the support shell through the first arc-shaped clamp (43) and the second arc-shaped clamp (46). 31) Move forward, keep the connecting line (22) fixed, push the support shell (31) to compress the linear spring (34), the linear spring (34) undergoes elastic deformation, the inner side of the support shell (31) slides on the outer side of the plug shell (21), complete the axial overload test, start the servo motor (53) to drive the rotating plate (61) to rotate, the rotating plate (61) and the arch plate (66) clamp the connecting line (22), thereby driving the connecting line (22) to twist, the twist of the connecting line (22) drives the plug shell (21) to twist, the position of the rear end of the support shell (31) inside the annular groove (24) changes, the arc surface (28) and the chamfered surface (35) provide space for the twist of the plug shell (21) inside the support shell (31); Step 3: The helical spring (34) is set between the support shell (31) and the plug shell (21) as an elastic support component, forming an elastic adaptive buffer mechanism. When the connector engagement test is subjected to axial overload or eccentric overload by external force, the linear spring (34) absorbs the overload energy through compression, tension or deformation, adjusts the relative position of the plug shell (21) and the support shell (31), and ensures the coaxial alignment of the plug assembly (2) and the socket assembly (1). The elastic force of the helical spring line itself provides the front engagement pressure of the plug assembly (2) and the socket assembly (1). After the test, the connection between the connecting line (22) and the torsion test assembly (6) is removed. The helical spring (34) drives the plug shell (21) and the support shell (31) to return to the original coaxial position by means of the rebound coefficient. Step 4: Using a double-layer nested structure in which the support shell (31) and the plug shell (21) are interlocked, the traditional single rigid shell is replaced by either the connector socket assembly (1) or the plug assembly (2). The assembly of the plug shell (21), the support shell (31) and the spiral structure spring (34) is completed by combining the inner mold injection molding and the outer mold injection molding process.
