Abstract
Description
Technical Field
[0001] This invention relates to the field of connector technology, and more specifically to a detachable cable connector with shielding function. Background Technology
[0002] Shielded separable cable connectors are widely used in power transmission and industrial control fields, such as industrial smart gateways. They are mainly used to achieve pluggable electrical connections between cables and equipment, and between cables. After the connector is plugged in, it is necessary not only to ensure that the internal conductive components have stable and reliable electrical contact performance, but also to form a continuous and closed shielding structure on the outer layer to block the leakage and intrusion of electromagnetic interference, and to ensure the integrity and stability of signal transmission. As the core functional unit of the connector, the locking mechanism directly determines the stability of the plugging state, the continuity of the shielding contact, and the safety and convenience of the separation operation. Existing detachable cable connectors typically employ either elastic snap-fit or steel ball locking mechanisms for locking and releasing. Elastic snap-fit connectors rely on the hook-and-loop engagement of an elastic arm for locking; releasing is achieved by pressing the unlock button, which deforms the elastic arm and disengages it. Steel ball locking, on the other hand, involves embedding a steel ball into a groove in the mating component during insertion. Locking and releasing are achieved through the axial movement of a sliding sleeve. The reliability of snap-fit locking depends on the structural rigidity of the elastic arm, while the locking strength of steel ball locking depends on the radial pressure exerted by the sliding sleeve on the steel ball. Both types of structures follow the same characteristic: the higher the locking tightness, the greater the resistance required to separate. However, in actual separation operations, operators often need to apply significant axial force. When the locking constraint is broken instantaneously, the elastic potential energy stored inside the connector is suddenly released, causing the connector to spring open at an uncontrollable speed, generating a momentary impact load. This impact can easily cause hidden damage to internal precision conductive components, insulating supports, and shielding layer contact surfaces, reducing connector insertion efficiency and weakening the long-term reliability of the shielding contact. Summary of the Invention
[0003] The purpose of this invention is to provide a detachable cable connector with shielding function to overcome the above-mentioned shortcomings in the technology.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a separable cable connector with shielding function, comprising a shielded end connection end and a cable connection end, wherein one end of the shielded end connection end is recessed inward to form a mating cavity, and an inner contact is connected between the mating cavity and the shielded end connection end. A disassembly and assembly assembly is provided between the shielded end connection end and the cable connection end, the disassembly and assembly assembly being used to guide the cable connection end and the inner contact inside the shielded end connection end to be inserted and removed, and at the same time forming a continuous closed shielded conductive path after insertion, ensuring that the connector has stable shielding performance; The disassembly and docking assembly includes a plug sleeve fixedly connected inside the cable connection end and a socket sleeve fixedly connected to one end of the shielded end connection end. The socket sleeve is fitted onto the outside of the inner contact. A guide sleeve is slidably connected to the outside of the socket sleeve. A fixing ring seat is fixedly fitted onto the outside of the shielded end connection end. A rotating locking ring is installed at one end of the fixing ring seat. Several locking tooth rings are provided between the rotating locking ring and the cable connection end. The outside of each locking tooth ring is provided with an annular tooth structure, and the teeth extend from the center to the edge in a gentle slope. The rotating locking ring is provided with a positioning component that is adapted to the locking tooth ring. The positioning component is used to drive the locking tooth ring to tilt towards the outside of the cable connection end and lock or separate from the cable connection end. A locking component is provided between the plug sleeve and the socket sleeve, and the locking component is used to guide the movement of the cable connection end and the shielding end during insertion and removal.
[0005] Preferably, the locking assembly includes a plurality of radial sliding holes formed on the outside of the socket sleeve and communicating with its interior, and a conical guide ring fixedly sleeved on the outside of the plug cylinder, wherein the two sides of the conical guide ring are provided with conical structures, and a locking ring groove is formed on the outside of the plug cylinder. Each of the radial sliding holes is slidably connected to a locking bead, and the locking bead is embedded into the locking ring groove through a tapered guide ring, thus constraining the plug tube inside the socket sleeve.
[0006] Preferably, a limiting pressure ring is fixedly connected inside the guide sleeve. The limiting pressure ring is slidably sleeved on the outside of the socket sleeve. A return spring is connected between the socket sleeve and the limiting pressure ring. The return spring applies a pushing force to one side of the limiting pressure ring through elastic force. At the same time, the inner wall of the limiting pressure ring abuts against the outer wall of the locking ball, thereby limiting the locking ball inside the radial sliding hole. The inside of the guide sleeve fits against the outside of the return spring.
[0007] Preferably, the positioning component includes a swing frame installed outside the locking tooth ring and an arc-shaped guide groove opened outside the rotating locking ring and communicating with its interior. The locking tooth ring is guided to move inside the arc-shaped guide groove. A transmission swing rod is fixedly connected to the outside of the swing frame. A hinge support is fixedly connected to the outside of the fixed ring seat. The top of the transmission swing rod is movably sleeved on the outside of the hinge support. The transmission swing rod swings along the inside of the arc-shaped guide groove through the hinge support. A toothed block fine-tuning component is provided between the swing frame and the locking toothed ring, and the toothed block fine-tuning component is used to drive the locking toothed ring to move along the inside of the swing frame.
[0008] Preferably, the transmission rocker arm is externally slidably sleeved with a transmission slide block, and the rotary locking ring is externally movably connected with a centering shaft, with one end of the centering shaft extending into the interior of the arc-shaped guide groove and fixedly connected to one side of the transmission slide block. The rotating locking ring is externally fixedly sleeved with a driven gear ring, and a servo motor is fixedly connected to one end of the fixed ring seat, and a driving gear that meshes with the driven gear ring is fixedly connected to one end of the servo motor.
[0009] Preferably, the toothed block fine-tuning assembly includes two guide seats fixedly connected inside the swing frame and a sliding seat embedded inside the locking tooth ring, and there is a gap between the two guide seats. One end of the swing frame is provided with an adjusting rod. One end of the adjusting rod is inserted into the interior of the two guide seats from one end of the swing frame, passes through the guide seats, and then forms a sliding fit with the other end of the swing frame. The sliding seat is internally fixedly connected with a connecting pin, which is located between two guide seats and fixedly sleeved on the outside of the adjusting rod.
[0010] Preferably, one end of one of the guide seats is fixedly connected to a threaded sleeve, and the threaded sleeve is fitted outside the adjusting rod and has a gap between it and the adjusting rod; a support ring is fixedly connected inside the swing frame, and the support ring is fitted outside the adjusting rod and has a gap between it and the adjusting rod. The support ring is externally fixedly connected with several clamping washers, and the threaded sleeve is externally screwed with an adjusting nut. One end of the adjusting nut has a tapered hole for inserting an adjusting rod.
[0011] Preferably, a flexible pad is installed on the side of the clamping pad near the outer wall of the adjusting rod, the interior of the tapered hole is designed as a tapered structure, and the inner wall of the tapered hole forms an inclined fit with the outer wall of the adjusting rod.
[0012] The technical effects and advantages provided by the present invention in the above technical solution are as follows: 1. In this invention, when the cable connection end and the shielding end connection end and the inner contact are separated, the locking toothed ring first moves in the opposite direction, disengaging from the outer wall of the cable connection end beforehand, releasing the radial constraint between the shielding end connection end and the cable connection end. Then, it pushes the guide sleeve to synchronously displace the limiting pressure ring, releasing the radial constraint on the locking pressure ball, allowing the locking pressure ball to enter a free state where it can float radially. When the cable connection end is pulled outward for axial separation, the locking pressure ball gradually retracts along the inclined surface of the tapered guide ring, completely disengaging from the locking ring groove, ultimately achieving separation between the shielding end connection end and the cable connection end. The entire separation process follows a two-stage action logic: first releasing the locking constraint, then performing axial pull-out. The locking pressure ball first completes the radial... Released, and then gradually withdrawn from the locked position by the inclined guide, the separation force only needs to overcome the sliding friction between the locking pressure ball and the inclined surface of the tapered guide ring. There is no hard scraping or impact load. Through the step-by-step action of unlocking first and then separating, the radial locking force between the shielded end connection end and the cable connection end disappears first. The two enter an axially sliding but fully controlled state. At this time, there is no stored energy to release, and no bouncing or impact will occur. This achieves low-resistance and damage-free separation of the connector, avoiding arcing of the conductive contact surface, tearing of the shielding layer or damage to the insulation caused by forced separation. It significantly improves the insertion and removal efficiency of the shielded end connection end and the cable connection end, while ensuring the stability of the locking state and the continuous reliability of the shielding contact. 2. In this invention, after the guide sleeve moves and resets, the inside of the limiting pressure ring immediately comes into contact with the top of the six locking pressure balls, keeping the locking pressure balls locked inside the radial sliding hole and the locking ring groove. At this time, the locking pressure balls simultaneously bear the reaction force of the locking ring groove and the constraint force of the inner wall of the limiting pressure ring, forming a double radial lock. This lock is evenly distributed at multiple points in the circumferential direction, tightly fitting the shield end connection end and the cable connection end, while ensuring that the shield end face is evenly stressed. 3. In this invention, the transmission slide and the transmission rocker move in a preset direction to avoid interference between them. Then, the rotation of the transmission rocker around the axis drives the swing frame to tilt towards the outside of the insertion cavity. The locking tooth ring moves synchronously with the swing frame, so that the movement trajectory of the locking tooth ring is a spatial arc. Then, the front end of the locking tooth ring first contacts the high point of the cable connection end shell. Before the cable connection end is inserted into the rotating locking ring, the three locking tooth rings surround the outside of the insertion cavity and push the cable connection end towards the center with the radial component force generated by the tilting action, and provide reverse support force. This effectively improves the disassembly and assembly efficiency of the cable connection end and the shielding end connection end, ensures the stable and reliable locking state, and further enhances the stability of the shielding connection. 4. The present invention uses a locking toothed ring, clamping gasket, support ring and guide seat to adjust the contact surface between the locking toothed ring and the cable connection end, so that the inclination angle of the tooth slope on the outside of the locking toothed ring is adapted to the outside of the cable connection end. At the beginning of the locking stroke, the synchronous ring frame has a small driving force, which corresponds to the low angle area of the tooth slope and provides small resistance. At the end of the locking stroke, the required locking force increases sharply, which corresponds to the high angle area of the tooth slope and provides the maximum structural rigidity and reaction force support, ensuring the reliability of the contact between the shielded end connection end and the shielding layer of the cable connection end after assembly. 5. This invention, through the arrangement of the hinged support, transmission rocker arm, and transmission slide, allows the locking tooth ring to approach the outside of the cable connection end in an inclined manner. This causes the outer teeth of the locking tooth ring to expand from the center to the edge in a gentle slope. Consequently, the flexible tooth tips of the locking tooth ring undergo elastic deformation under high pressure. When the locking tooth ring locks with the cable connection end, the driving force is gradient transmitted from the high rigidity area at the center of the teeth to the flexible area at the edge. As the locking depth increases, the contact area gradually expands along the gentle slope. The force flow is not established instantaneously on a narrow contact line, but rather gradually spreads and engages with the cable connection end. This provides anti-loosening protection between the cable connection end and the shielded end connection end. Under the pulling of the cable connection end, the locking state does not fail, ensuring the reliability of the shielded connection and ensuring that the separable shielded end connection end and the cable connection end have good shielding effectiveness in the locked state. 6. This invention, through the arrangement of clamping gaskets, support rings, and guide seats, enables the locking toothed ring to move horizontally within the swing frame. This causes the contact position between the locking toothed ring and the cable connection end to shift axially, avoiding old contact areas that have undergone slight plastic deformation or surface polishing during long-term locking. The locking force is tightly applied to the outer shell surface, providing a safe window for connector assembly and disassembly. Simultaneously, it also drives the locking toothed ring to rotate circumferentially within the swing frame. The increased tilting force of the locking toothed ring fully utilizes the advantages of the sawtooth engagement, thereby simultaneously improving the contact reliability between the locking toothed ring and the cable connection end. Ultimately, this ensures the stability and conductivity reliability of the shielding layer contact between the shielded end connection end and the cable connection end. Attached Figure Description

[0016] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0017] This invention provides, for example Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The detachable cable connector with shielding function shown includes a shielded end connection end 1 and a cable connection end 11. One end of the shielded end connection end 1 is recessed inward to form a mating cavity 13. An inner contact 12 is connected between the mating cavity 13 and the shielded end connection end 1. A disassembly and assembly assembly 2 is provided between the shielded end connection end 1 and the cable connection end 11. The disassembly and assembly assembly 2 is used to guide the cable connection end 11 and the inner contact 12 inside the shielded end connection end 1 to perform insertion and removal. At the same time, after insertion, a continuous closed shielded conductive path is formed to ensure that the connector has stable shielding performance. The disassembly and assembly assembly 2 includes a plug sleeve 22 fixedly connected inside the cable connection end 11 and a socket sleeve 21 fixedly connected to one end of the shielded end connection end 1. The socket sleeve 21 is fitted onto the outside of the inner contact 12. A guide sleeve 23 is slidably connected to the outside of the socket sleeve 21. A fixing ring seat 24 is fixedly fitted onto the outside of the shielded end connection end 1. A rotating locking ring 25 is installed at one end of the fixing ring seat 24. Several locking toothed rings 26 are provided between the rotating locking ring 25 and the cable connection end 11. The outside of each locking toothed ring 26 is provided with an annular tooth structure, and the teeth extend from the center to the edge in a gentle slope. An assembly gap is left between the plug sleeve 22 and the cable connection end 11. The plug-in component inside the cable connection end 11 is housed in the inner cavity of the plug sleeve 22. The guide sleeve 23 is arranged between the plug sleeve 22 and the cable connection end 11, which can provide support for the cable connection end. The relative displacement between the cable connection end 11 and the shielded end 1 forms a guiding constraint, ensuring coaxiality and smoothness during insertion and removal. Three sets of locking tooth rings 26 are arranged circumferentially around the outside of the cable connection end 11. The protruding teeth of the locking tooth rings 26 are made of flexible material, possessing moderate deformation capability, ensuring a stable fit and contact between the locking tooth rings 26 and the outer wall of the cable connection end 11. The specific structure and working principle of the shielded end 1 and the cable connection end 11 are existing technologies and will not be elaborated upon in this application. In existing connector applications, the shielded end 1 is composed of a shielded shell and a shielding layer. After grounding, it can completely enclose the internal high-voltage electric field within the insulating structure, maintaining the outer surface of the connector at zero potential. After normal assembly, the outer surface can be safely touched; simultaneously, it can effectively suppress electromagnetic interference and prevent corona discharge. A locking component 3 is provided between the plug sleeve 22 and the socket sleeve 21. The locking component 3 is used to guide the movement of the cable connection end 11 and the shielding end connection end 1 during insertion and removal. The locking component 3 includes several radial sliding holes 34 that are opened on the outside of the socket sleeve 21 and communicate with its interior, and a conical guide ring 31 that is fixedly sleeved on the outside of the plug sleeve 22. The two sides of the conical guide ring 31 are set with conical structures. A locking ring groove 32 is opened on the outside of the plug sleeve 22. Each radial sliding hole 34 is slidably connected with a locking ball 35, and the locking ball 35 is embedded into the locking ring groove 32 through the tapered guide ring 31, thus constraining the plug tube 22 inside the socket sleeve 21; A limiting ring 33 is fixedly connected inside the guide sleeve 23. The limiting ring 33 is slidably sleeved on the outside of the socket sleeve 21. A return spring 36 is connected between the socket sleeve 21 and the limiting ring 33. The return spring 36 applies a pushing force to one side of the limiting ring 33 through elastic force. At the same time, the inner wall of the limiting ring 33 abuts against the outer wall of the locking ball 35, thus limiting the locking ball 35 inside the radial sliding hole 34. The inside of the guide sleeve 23 fits against the outside of the return spring 36. There are six radial sliding holes 34 in total, and the number of locking balls 35 corresponds to and is matched with the radial sliding holes 34. The internal groove size of the locking ring groove 32 is matched with the locking ring groove 35. The outer diameter of the locking ball 35 is matched to ensure that during the axial retraction of the plug sleeve 22, the locking ball 35 can generate a small radial float in the locking ring groove 32, so that its outer wall can climb upward along the corresponding side slope of the tapered guide ring 31 and finally smoothly get out of the constraint of the locking ring groove 32. The socket sleeve 21 adopts a T-shaped structure design. One end of the return spring 36 is positioned against the radial boss part of the socket sleeve 21. The return spring 36 is slidably sleeved on the outside of the column section of the socket sleeve 21. The limiting pressure ring 33 is sleeved on the outside of the socket sleeve 21. The two together form an approximately I-shaped installation space, so that the return spring 36 is limited between the socket sleeve 21 and the limiting pressure ring 33.
[0018] refer to Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, the rotating locking ring 25 has a positioning component 4 adapted to the locking tooth ring 26 inside. The positioning component 4 is used to drive the locking tooth ring 26 to tilt towards the outside of the cable connection end 11 and lock or separate from the cable connection end 11. The positioning component 4 includes a swing frame 42 installed outside the locking tooth ring 26 and an arc-shaped guide groove 46 opened outside the rotating locking ring 25 and communicating with its interior. The locking tooth ring 26 is guided to move inside the arc-shaped guide groove 46. A transmission swing rod 44 is fixedly connected to the outside of the swing frame 42. A hinge support 41 is fixedly connected to the outside of the fixed ring seat 24. The top of the transmission swing rod 44 is movably sleeved on the outside of the hinge support 41. The transmission swing rod 44 swings along the inside of the arc-shaped guide groove 46 through the hinge support 41. A toothed block fine-tuning component 5 is provided between the swing frame 42 and the locking toothed ring 26, and the toothed block fine-tuning component 5 is used to drive the locking toothed ring 26 to move along the inside of the swing frame 42; the transmission slide 43 is slidably sleeved on the outside of the transmission swing rod 44, and the centering shaft 45 is movably connected to the outside of the rotating lock ring 25, and one end of the centering shaft 45 extends into the inside of the arc-shaped guide groove 46 and is fixedly connected to one side of the transmission slide 43. A driven gear ring 49 is fixedly sleeved on the outside of the rotary locking ring 25. A servo motor 47 is fixedly connected to one end of the fixed ring seat 24, and a drive gear 48 that meshes with the driven gear ring 49 is fixedly connected to one end of the servo motor 47. The tooth block fine adjustment assembly 5 includes two guide seats 51 fixedly connected inside the swing frame 42 and a sliding seat 52 embedded inside the locking tooth ring 26. There is a gap between the two guide seats 51. One end of the swing frame 42 is provided with an adjustment rod 54. One end of the adjustment rod 54 is inserted into the interior of the two guide seats 51 from one end of the swing frame 42. After passing through the guide seats 51, it forms a sliding fit with the other end of the swing frame 42. A connecting pin 55 is fixedly connected inside the sliding seat 52. The connecting pin 55 is located between the two guide seats 51 and is fixedly sleeved on the outside of the adjusting rod 54. One end of one of the guide seats 51 is fixedly connected to a threaded sleeve 53, and the threaded sleeve 53 is sleeved on the outside of the adjusting rod 54 and there is a gap between the adjusting rod 54 and the inside of the swing frame 42 is fixedly connected to a support ring 56, and the support ring 56 is sleeved on the outside of the adjusting rod 54 and there is a gap between the adjusting rod 54 and the adjusting rod 54. Several clamping washers 57 are fixedly connected to the outside of the support ring 56. An adjusting nut 58 is screwed onto the outside of the threaded sleeve 53. One end of the adjusting nut 58 has a tapered hole 59 for the adjusting rod 54 to be inserted. A flexible pad is installed on the side of the clamping washer 57 near the outer wall of the adjusting rod 54. The inside of the tapered hole 59 is a tapered structure, and the inner wall of the tapered hole 59 forms an oblique fit with the outer wall of the adjusting rod 54. The outer wall section of the rod 54 that mates with the clamping washers 57 is designed with a concave-convex particle annular groove structure, which can increase the friction between the contact surfaces and ensure the stability of the clamping washers 57 and the adjusting rod 54. Three clamping washers 57 are provided in total and are arranged circumferentially around the outside of the adjusting rod 54.
[0019] Working principle: When using: refer to Figures 2-7 As shown, when electrical equipment needs to be connected and disconnected via connectors, the disassembly process is as follows; First, the servo motor 47 drives the drive gear 48 to rotate synchronously. The drive gear 48 meshes with the driven gear ring 49, causing the rotating locking ring 25 to rotate circumferentially along the end of the fixed ring seat 24. The centering shaft 45 moves synchronously with the rotating locking ring 25, causing the transmission slide 43 to move in a semi-circular arc along the arc-shaped guide groove 46. During the movement of the transmission slide 43, its inner wall and the outer wall of the transmission rocker arm 44 come into contact and push against each other, driving the transmission rocker arm 44 to swing around the hinged support 41 around a fixed axis. A friction is generated between the transmission rocker arm 44 and the transmission slide 43. Relative sliding allows for orderly movement along a preset trajectory, avoiding motion interference. Subsequently, the oscillation of the transmission rocker arm 44 around its axis causes the swing frame 42 to tilt outwards from the insertion cavity 13, and the locking toothed ring 26 moves outwards synchronously with the swing frame 42, releasing the axial locking constraint on the cable connection end 11. Then, the guide sleeve 23 is driven to move axially between the socket sleeve 21 and the insertion cavity 13. At the same time, the guide sleeve 23 slides synchronously along the inner wall of the cable connection end 11 and the outer wall of the plug cylinder 22, and gradually slides out from inside the cable connection end 11. During the movement of the guide sleeve 23, the limiting pressure ring 33 is pushed to move axially synchronously. The return spring 36 located between the socket sleeve 21 and the limiting pressure ring 33 is compressed. As the limiting pressure ring 33 moves, its inner ring disengages from the outer wall of the six locking pressure balls 35, releasing the radial limitation of the six locking pressure balls 35 in the corresponding radial sliding holes 34. The cable connection end 11 is pulled outward, causing the plug cylinder 22 to move axially outward along the inside of the socket sleeve 21. At this time, the part of the six locking pressure balls 35 embedded in the locking ring groove 32 and the tapered guide ring 31 are connected. The conical surfaces form an inclined fit. As the conical guide ring 31 moves outward along the plug cylinder 22, the bottom of the six locking pressure beads 35 climbs upward along the conical surface of the conical guide ring 31 and passes the top of the cone. During this process, each locking pressure bead 35 moves outward radially along the corresponding radial sliding hole 34. After passing the top of the cone, the locking pressure bead 35 slowly falls back along the other side of the conical surface of the conical guide ring 31 and finally surrounds the outer periphery of the plug cylinder 22, completely breaking free from the constraint of the locking ring groove 32, so that the cable connection end 11 is separated from the shielded end connection end 1 and the inner contact 12. refer to Figures 2-5As shown, secondly, the connector can maintain the stability of the locked state between the cable connection end 11 and the shielded end connection end 1 and the continuous reliability of the shielded contact even after multiple disassembly and assembly cycles. When the shielding structure is grounded, the internal high-voltage electric field can be sealed inside the insulation structure, keeping the outer surface of the connector at zero potential. The end of the cable connection end 11 is passed through the inner cavity of the rotating locking ring 25 and axially pushed towards the guide sleeve 23. The guide sleeve 23 first embeds into the annular gap between the cable connection end 11 and the plug sleeve 22, forming a coaxial guide for the insertion stage of the cable connection end 11, ensuring proper alignment during insertion. As the cable connector 11 continues to advance, the plug cylinder 22 gradually inserts into the socket sleeve 21, simultaneously pushing the guide sleeve 23 to drive the limiting pressure ring 33 to slide axially along the outer wall of the socket sleeve 21. During this forward movement, the limiting pressure ring 33 gradually disengages from the radial contact with the six locking pressure balls 35, allowing the locking pressure balls 35 to float freely radially within their corresponding radial sliding holes 34. The return spring 36 is compressed as the limiting pressure ring 33 moves. As the plug cylinder 22 continues to penetrate deeper, its end first contacts the bottom of the six locking pressure balls 35, causing the locking pressure balls 35 to slide along their corresponding radial paths. As the hole 34 pushes outward, the tapered guide ring 31 moves axially synchronously with the plug sleeve 22, and its tapered surface gradually comes into contact with the bottom of the locking beads 35. The six locking beads 35 climb up along the tapered surface of the tapered guide ring 31, pass the top of the cone, and fall back along the other side of the tapered surface. Throughout the process, the locking beads 35 always make directional radial movements along the radial sliding hole 34, and finally slide into the locking ring groove 32 to form a fitting. Then, the axial thrust of the guide sleeve 23 is slowly released, and the compressive force on the return spring 36 between the limiting pressure ring 33 and the socket sleeve 21 gradually decreases, and the elastic reaction of the return spring 36... When the limiting pressure ring 33 is pushed to slide back and reset, its inner ring immediately forms radial contact with the top of the six locking pressure beads 35, constraining and locking the locking pressure beads 35 in the radial sliding hole 34 and the locking ring groove 32. At this time, the locking pressure beads 35 simultaneously bear the axial limiting reaction force of the locking ring groove 32 and the radial constraint force of the inner wall of the limiting pressure ring 33, forming a double radial locking. This locking structure is evenly distributed at multiple points along the circumference, which can make the mating end face of the shielded end connection 1 and the cable connection end 11 fit tightly, while ensuring that the shielded layer end face is evenly stressed and fully pressed. refer to Figure 3 , Figure 6 and Figure 7As shown, after the locking ball completes radial locking, the internal components of the cable connection end 11 and the inner contact 12 form a tight insertion fit. At this time, the servo motor 47 drives the drive gear 48 to rotate synchronously. The drive gear 48 meshes with the driven gear ring 49, driving the rotating locking ring 25 to rotate circumferentially along the end of the fixed ring seat 24. The centering shaft 45 moves synchronously with the rotating locking ring 25, driving the transmission slide 43 to move in a semi-circular arc along the arc guide groove 46. During the movement of the transmission slide 43, its inner wall and the outer wall of the transmission swing rod 44 form abutment and pull, driving the transmission swing rod 44 to swing around the hinge support 41 around a fixed axis. The transmission swing rod 44 and the transmission slide 43 produce relative sliding. The two move in an orderly manner along a preset trajectory to avoid motion interference. Then, the swing of the transmission swing rod 44 around the axis drives the swing frame 42 to tilt and retract towards the inner side of the insertion cavity 13. The locking gear ring 26 moves synchronously with the swing frame 42, and its movement trajectory is empty. The locking tooth ring 26 first contacts the highest point of the cable connection end 11 shell with the inter-arc line. The radial component force generated by the tilting action pushes the cable connection end 11 towards the center for alignment. The outer peripheral teeth of the locking tooth ring 26 extend from the center to the edge in a gentle slope. The flexible tooth tip at the top of the tooth undergoes elastic deformation under the action of the clamping force. When the locking tooth ring 26 engages with the cable connection end 11, the driving force is gradient transmitted from the high rigid area at the center of the tooth to the flexible area at the edge. As the locking depth increases, the contact area gradually expands along the gentle slope. The force is not established instantaneously on the narrow contact line, but is gradually spread to achieve fit with the cable connection end 11. This structure provides a reliable anti-loosening guarantee for the cable connection end 11 and the shielding end connection end 1. Even if the cable connection end 11 is pulled by external force, the locking state will not fail. This ensures the long-term reliability of the shielding connection and also ensures that both have excellent shielding performance in the locking state. refer to Figure 1 , Figure 3 and Figure 8As shown, when it is necessary to fine-tune the installation angle and horizontal position of the locking toothed ring 26 within the swing frame 42, this can be achieved through a matching adjustment mechanism: Rotate the adjusting nut 58 to form a helical drive with the threaded sleeve 53. The adjusting nut 58 moves axially along the outer wall of the threaded sleeve 53. During the rotation of the adjusting nut 58, the tapered hole 59 inside it slides along the outer wall of the clamping shim 57, gradually increasing the distance between them. The radial pressure of the tapered hole 59 on the clamping shim 57 continuously weakens, and the part of the clamping shim 57 near the adjusting rod 54 elastically rebounds, gradually reducing the clamping force against the outer wall of the adjusting rod 54. This allows the adjusting rod 54 to be in a movable state between the threaded sleeve 53 and the two guide seats 51. At this time, pushing the adjusting rod 54 along the threaded sleeve 53 and the two guide seats 51... The guide seat 51 slides axially, and the connecting pin 55 moves synchronously with the adjusting rod 54, causing the sliding seat 52 to slide synchronously along the outer wall of the two guide seats 51. This allows for fine adjustment of the horizontal position of the locking tooth ring 26 within the swing frame 42, and synchronously changes the axial contact position between the locking tooth ring 26 and the cable connection end 11. Rotating the adjusting rod 54 causes it to rotate circumferentially along the threaded sleeve 53 and the two guide seats 51. The adjusting rod 54, through the connecting pin 55, drives the sliding seat 52 to rotate along the outer wall of the guide seat 51, thus achieving fine adjustment of the relative angle between the locking tooth ring 26 and the insertion cavity 13. This further improves the reliability of the contact between the locking tooth ring 26 and the cable connection end 11, and ultimately ensures the stability of the shielding layer contact between the shielded end connection end 1 and the cable connection end 11.
