Description

Technical Field

[0001] This invention relates to the field of connector technology, and more particularly to a magnetic connector. Background Technology

[0002] With the booming development of the automotive industry and the iterative upgrade of automotive electronics technology, magnetic connectors, as a new type of electrical connection solution, are gradually penetrating from the consumer electronics field to the automotive field. In in-vehicle intelligent cockpits, battery management systems, autonomous driving sensor modules, and in-vehicle charging equipment, magnetic connectors have received widespread attention due to their practicality and convenience. However, the continuous bumps, road impacts, high-frequency engine vibrations, and the enormous inertial forces generated by sudden acceleration, deceleration, and braking during vehicle operation can cause the male and female terminals of the magnetic connector to detach. This can lead to power failure and restart of the vehicle's central control unit, loss of sensor data, and even false alarms or loss of control in the powertrain or braking system, easily causing serious safety accidents. Therefore, to prevent the male and female terminals of the magnetic connector from detaching, the magnetic force of the in-vehicle magnetic connector needs to be set as high as possible. However, during normal vehicle assembly, maintenance, or after-sales parts replacement, repair personnel frequently need to disconnect the magnetic connector. Due to the excessive magnetic force, technicians often cannot complete the separation operation with one hand and must hold both sides of the connector with both hands or use hard tools such as screwdrivers to pry it open. This violent pulling can cause the spring pins (Pogo pins) inside the connector to be easily subjected to lateral shear forces, resulting in permanent plastic deformation, breakage of the spring, or bending of the conductive pins, directly rendering the connector unusable. Secondly, when the connector needs to be disconnected during vehicle repair, the repair personnel's hands may slip and hit surrounding metal parts due to violent pulling, posing a safety risk of injury. Summary of the Invention

[0003] The purpose of this invention is to provide a magnetic connector to solve the problem mentioned in the background art that existing high-force magnetic connectors are inconvenient to detach.

[0004] To achieve the above objectives, the basic solution of the present invention is as follows: A magnetic connector includes a male terminal assembly and a female terminal assembly. The male terminal assembly includes a male terminal housing, a male terminal disposed within the male terminal housing, and a male terminal magnetic attractor. The female terminal assembly includes a female terminal housing, a female terminal disposed within the female terminal housing, and a female terminal magnetic attractor that magnetically attracts the male terminal magnetic attractor. The connector also includes a magnetic force adjustment mechanism for adjusting the magnetic force between the male terminal magnetic attractor and the female terminal magnetic attractor. The magnetic adjustment mechanism includes an adjustment ring rotatably connected to the female end housing and a linkage unit disposed within the female end housing. Rotating the adjustment ring causes the female end magnetic attractor to move via the linkage unit, thereby adjusting the distance between the female end magnetic attractor and the male end magnetic attractor.

[0005] Furthermore, the female end housing is a rotating body, and a first annular groove is coaxially provided on the outer wall of the female end housing. The adjusting ring is disposed in the first annular groove and rotatably connected to the female end housing.

[0006] Furthermore, a second annular groove is recessed on the mating end surface of the female end housing and is coaxially arranged with the female end housing. The female end magnetic attractor is an annular magnet that is slidably arranged in the second annular groove.

[0007] Furthermore, the linkage unit includes a plurality of radially distributed connecting plates and a first sliding groove corresponding to the connecting plates. The connecting plates are all arranged radially along the female end housing. The first sliding groove is arranged parallel to the axial direction of the female end housing. The first sliding groove connects the first annular groove and the second annular groove. The first end of the connecting plate is located in the first sliding groove, and the second end of the connecting plate is located in the second annular groove and connected to the female end magnetic suction component. The inner wall of the adjusting ring is provided with an internal thread, and the end face of the first end of the connecting plate is fitted with an external thread. The adjusting ring and the connecting plate are threadedly connected.

[0008] When the adjusting ring is rotated, the connecting plate is driven by the threaded transmission to move the female magnetic chuck along the axis of the female housing away from the male magnetic chuck, thereby reducing the magnetic attraction between the female and male magnetic chucks and facilitating the separation of the female and male components.

[0009] Furthermore, the linkage unit also includes a third annular groove disposed on the mating end face of the female end housing, an annular plate slidably connected to the third annular groove, and a movable plate corresponding to the connecting plate. The third annular groove is coaxially disposed with the female end housing and is located between the second annular groove and the outer wall of the female end housing. The movable plate is disposed parallel to the axis of the female end housing. The connecting plate is provided with a first through groove that slidably engages with the movable plate. One end of the movable plate is fixedly connected to the annular plate, and the other end of the movable plate is inserted into the first through groove. A first stepped surface and a second stepped surface are formed on the side of the movable plate away from the axis of the female end housing. A transition slope is provided between the first stepped surface and the second stepped surface. A spring sheet is provided on the inner wall of the first through groove near the axis of the female end housing to force the linkage... The connecting plate moves towards the axis of the female end housing. A connecting block corresponding to the connecting plate is fixed on the inner end face of the female end magnetic chuck. The connecting block is provided with a second through groove that slides with the connecting plate. The lower end of the connecting plate is inserted into the second through groove. A first spring that forces the female end magnetic chuck to move towards the male end assembly is provided in the second annular groove. A second spring that forces the annular plate to move towards the male end assembly is provided in the third annular groove. When the moving plate moves to make the first step surface fit against the inner wall of the first through groove, the upper end face of the connecting plate is separated from the inner wall of the adjusting ring. When the moving plate moves to make the second step surface fit against the inner wall of the first through groove, the external thread on the upper end face of the connecting plate engages with the internal thread on the inner wall of the adjusting ring.

[0010] Furthermore, the annular plate has two asymmetrically distributed positioning pins on its end face near the male end housing, and the male end housing has positioning pin holes that mate with the positioning pins on its mating end face.

[0011] Furthermore, the male end magnetic chuck is an annular magnet embedded on the mating end surface of the male end housing, and the male end magnetic chuck and the female end magnetic chuck are coaxially arranged.

[0012] Furthermore, the female end housing is provided with a female end connection cavity at the end away from the male end assembly, and the male end housing is provided with a male end connection cavity at the end away from the female end assembly.

[0013] Furthermore, the male terminal is an elastic contact pin arranged along the axis of the male terminal housing, with the front end of the male terminal extending out of the mating end face of the male terminal housing. The female terminal is arranged parallel to the axis of the female terminal housing and coaxial with the male terminal. The end of the female terminal near the male terminal housing has a tubular insertion hole structure. When the male terminal assembly and the female terminal assembly are correctly mated, the front end of the male terminal is inserted into the tubular insertion hole on the female terminal and makes close contact with the female terminal.

[0014] Furthermore, the female end housing is provided with a female end clamping plate for engaging the female end housing with the peripheral component, and the male end housing is provided with a male end clamping plate for engaging the male end housing with the peripheral component.

[0015] In this application, when the male end component is not connected to the female end component, under the elastic force of the second spring, the outer end of the annular plate extends beyond the mating end face of the female end housing. At this time, the first stepped surface is located in the first slide groove near the third annular groove, while the connecting plate, under the elastic force of the first spring, is located in contact with the side wall of the first slide groove and cannot move further towards the mating end face of the female end housing. The female end magnetic attractor is also located at the position closest to the male end magnetic attractor. At this time, the first stepped surface is located at the position corresponding to the through groove of the connecting plate, and the thickness of the moving plate at the first stepped surface is less than the thickness of the moving plate at the second stepped surface. Therefore, under the elastic force of the spring plate, the upper end of the connecting plate disengages from the inner wall of the adjusting ring. Rotating the adjusting ring will not cause the connecting plate to move the female end magnetic attractor away from the male end component.

[0016] When the female end assembly is docked with the male end assembly, the two locating pins on the female end housing are aligned with the two locating pin holes on the male end housing, and force is applied along the axial direction to bring the female end housing and the male end housing closer together. This causes the female end magnetic attractor and the male end magnetic attractor to attract each other, making the female end housing press against the male end housing. At this time, the elastically expandable male terminal and the female terminal are in close contact to transmit electrical signals. During the process of the male end housing 201 moving to contact the female end housing, the annular plate is pressed and slid back into the third annular groove by the male end housing, which causes the moving plate to move away from the male end housing so that the second step surface is located at the position corresponding to the first through groove on the connecting plate. Since the thickness of the moving plate at the second step surface increases, it forces the connecting plate to slide away from the axis of the female end housing so that the external thread on the first end face of the connecting plate engages with the internal thread on the inner wall of the adjusting ring.

[0017] When it is necessary to separate the female and male components, manually rotate the adjusting ring. Through threaded transmission, the connecting plates synchronously move the female magnetic chuck away from the male housing from different positions, increasing the distance between them. Since the magnetic force of a magnet is inversely proportional to the square of the distance, as the distance between the female and male magnetic chucks increases, the magnetic force between them decreases rapidly and non-linearly, allowing for easy separation. After separation, the outer end of the annular plate extends out of the female housing again under the cooperation of the first spring, the second spring, and the spring plate. The female magnetic chuck returns to its initial position closest to the male component, and the connecting plate returns to its initial position away from the adjusting ring. This allows for the repetition of the aforementioned actions and functions during subsequent docking and separation.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects: 1. When the male and female components are close together, they automatically and quickly adsorb and connect. The strong magnetic attraction of the female and male components can be used to prevent the male and female components from separating during use. It is suitable for use in environments with bumps and vibrations. When it is necessary to separate the male and female components, the magnetic attraction can be reduced by rotating the adjustment ring, which facilitates the quick separation of the male and female components. 2. In this design, the connecting plate and adjusting ring can only be connected via threaded transmission after the male and female components are mated. Only then can rotating the adjusting ring adjust the position of the female magnetic component and thus the magnetic force. When the male and female components are not mated, the female magnetic component is not controlled by the adjusting ring. Therefore, under the force of the first spring, the female magnetic component is positioned close to the mating end face of the female housing, maximizing the magnetic force after mating. Threaded transmission has a large transmission ratio and slow axial movement. Therefore, this design allows for easy rotation of the adjusting ring to force the female magnetic component away from the male magnetic component, significantly reducing the magnetic force between them and avoiding the adverse effects of direct, forceful pulling.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0039] The magnetic connector in this embodiment, such as Figures 1-16 As shown, it includes a male terminal assembly 20 and a female terminal assembly 10. The male terminal assembly 20 includes a male terminal housing 201, a male terminal 202 disposed within the male terminal housing 201, and a male terminal magnetic attractor 203. The female terminal assembly 10 includes a female terminal housing 101, a female terminal 102 disposed within the female terminal housing 101, a female terminal magnetic attractor 103 that magnetically attracts the male terminal magnetic attractor 203, and a magnetic force adjustment mechanism for adjusting the magnitude of the magnetic attraction between the male terminal magnetic attractor 203 and the female terminal magnetic attractor 103. When the male terminal component 20 and the female terminal component 10 are assembled to form a magnetic connector, the magnetic attraction between the male terminal magnetic member 203 and the female terminal magnetic member 103 attracts the male terminal component 20 and the female terminal component 10 together. At this time, the male terminal 202 and the female terminal 102 are aligned and in close contact to transmit electrical signals. When it is necessary to separate the male terminal component 20 and the female terminal component 10, the magnetic force adjustment mechanism is used to adjust and drive the female terminal magnetic member 103 to move away from the male terminal component 20, thereby increasing the distance between the male terminal magnetic member 203 and the female terminal magnetic member 103, and thus reducing the magnetic attraction between the female terminal magnetic member 103 and the male terminal magnetic member 203, so as to facilitate and easily separate the male terminal component 20 and the female terminal component 10.

[0040] Combination Figures 1-5 , Figure 10As shown, both the female end housing 101 and the male end housing 201 are approximately rotating bodies. Both the female end housing 101 and the male end housing 201 are made of insulating material, preferably glass fiber reinforced high-temperature nylon, which is injection molded. In order to facilitate the installation of other components inside the female end housing 101 and to reduce the molding difficulty of the injection mold, as a preferred embodiment of the present invention, the female end housing 101 is not integrally molded, but adopts a split assembly structure. After the corresponding components are installed, they can be sealed and fixed by means of snap-fit, screw connection, ultrasonic welding, bonding, etc. to form a complete female end housing 101. The split structure of the female end housing 101 is only a preferred solution for easy processing and assembly and does not constitute a limitation on the scope of protection of this application. When the male terminal assembly 20 and the female terminal assembly 10 are mated to form a connector, the end face of the male terminal housing 201 that abuts against the female terminal housing 101 is defined as the mating end face of the male terminal housing 201, and the end face of the female terminal housing 101 that abuts against the male terminal housing 201 is defined as the mating end face of the female terminal housing 101. A circular female terminal connection cavity 1013 is provided at the end of the female terminal housing 101 away from the male terminal assembly 20, and a circular male terminal connection cavity 2013 is provided at the end of the male terminal housing 201 away from the female terminal assembly 10. The female terminal connection cavity 1013 and the male terminal connection cavity 2013 are used as the tail interface space for the female terminal housing 101 and the male terminal housing 201 to make physical and electrical connections with external cables, wires or other equipment. The metal core of the external wire will be connected to the tail of the female terminal 102 and the male terminal 202 in this cavity by spot welding, laser welding or crimping. The female end housing 101 is provided with a female end clamping plate 1014 for engaging the female end housing 101 with peripheral components such as cable holders, and the male end housing 201 is provided with a male end clamping plate 2014 for engaging the male end housing 201 with peripheral components or other mounting bases.

[0041] The mating end surface of the female end housing 101 is recessed with a second annular groove 1012 coaxially arranged with the female end housing 101. The female end magnetic absorbing member 103 is an annular magnet slidably disposed in the second annular groove 1012. The mating end surface of the male end housing 201 is recessed with a fourth annular groove 2011 coaxial with the male end housing 201. The male end magnetic absorbing member 203 is an annular magnet embedded in the fourth annular groove 2011. The male end magnetic absorbing member 203 is tightly embedded in the fourth annular groove 2011 or is glued to the fourth annular groove 2011 with adhesive. The male end magnetic absorbing member 203 and the female end magnetic absorbing member 103 are coaxially aligned. When the female end magnetic absorbing member 103 approaches the male end magnetic absorbing member 203, the two attract each other. After the male end assembly 20 and the female end assembly 10 are mated and tightly attracted to form a connector, there is a small gap between the female end magnetic absorbing member 103 and the male end magnetic absorbing member 203, and they are not in contact.

[0042] The male terminal 202 is an elastic contact pin arranged along the axis of the male terminal housing 201. The male terminal 202 is fixedly connected to the male terminal housing 201. In this embodiment, there are two male terminals 202. In other feasible embodiments, there may be one, three, four or other numbers of male terminals 202. The male terminal 202 is fixed inside the male terminal housing 201 in a direction parallel to the axis of the male terminal housing 201. The front end of the male terminal 202 extends out of the mating end face of the male terminal housing 201. The elastic contact pin is a conventional spring pin (Pogo Pin) structure in the art, which includes a fixed end, a movable pin, and an elastic element (such as a helical spring or a spring sheet) located between the fixed end and the movable pin. Under the drive of the elastic element, the movable pin has a floating displacement capability of axial extension and retraction relative to the fixed end. This application does not particularly limit the specific internal structure of the elastic contact pin. Its specific shape, size, elastic coefficient, etc. can be obtained by those skilled in the art by purchasing commercially available standard parts according to the required contact pressure and conduction current. It will not be described in detail here.

[0043] The female terminal 102 and male terminal 202 are correspondingly arranged. The female terminal 102 is fixedly connected to the female terminal housing 101. The female terminal 102 is arranged parallel to the axis of the female terminal housing 101 and coaxial with the corresponding male terminal 202, so that when the male terminal assembly 20 and the female terminal assembly 10 are mated, the male terminal 202 and the female terminal 102 are aligned and in contact. The end of the female terminal 102 near the male terminal housing 201 has a tubular insertion hole structure. When the male terminal assembly 20 and the female terminal assembly 10 are correctly mated, the front end of the male terminal 202 is inserted into the tubular insertion hole on the female terminal 102 and in close contact with the female terminal 102. When the male terminal 202 is selected to be a conventional elastic contact pin, the female terminal 102 is usually sold in combination with the elastic contact pin. Its specific structure is a mature existing conventional technology and will not be described in detail here.

[0044] The magnetic force adjustment mechanism includes an adjustment ring 31 rotatably connected to the female end housing 101 and a linkage unit disposed within the female end housing 101. Rotating the adjustment ring 31 forces the female end magnetic attractor 103 to move through the linkage unit, thereby adjusting the distance between the female end magnetic attractor 103 and the male end magnetic attractor 203, so as to adjust the magnitude of the magnetic attraction force between the female end magnetic attractor 103 and the male end magnetic attractor 203.

[0045] The outer wall of the female end housing 101 is recessed along the radial direction of the female end housing 101, and is coaxial with the female end housing 101. The adjusting ring 31 is an annular body. The adjusting ring 31 is disposed in the first annular groove 1011 and is rotatably connected to the female end housing 101. The adjusting ring 31 can be twisted to rotate around the axis of the female end housing 101. The outer wall of the adjusting ring 31 is flush with the outer wall of the female end housing 101. The inner wall of the adjusting ring 31 is provided with internal threads.

[0046] The linkage unit includes a plurality of radially distributed connecting plates 321 and a first sliding groove 322 corresponding to each connecting plate 321. The radially distributed connecting plates 321 are centered on the axis of the mother end housing 101, and are arranged radially along the mother end housing 101. In this embodiment, six connecting plates 321 are radially distributed. In other feasible embodiments, the number of connecting plates 321 can be four, five, seven, eight, or other numbers depending on the actual situation. The first sliding groove 322 corresponds one-to-one with each connecting plate 321. The first sliding groove 322 is parallel to the axis of the mother end housing 101 and connects the first annular groove 1011 and the second annular groove 1012 radially along the mother end housing 101. The first end of the connecting plate 321 is located in the first annular groove 1011, and the second end of the connecting plate 321 is located in the second annular groove 1012 and connected to the female magnetic chuck 103. The end face of the first end of the connecting plate 321 is an arc-shaped surface adapted to the inner wall of the adjusting ring 31. The end face of the first end of the connecting plate 321 is provided with an external thread that mates with the internal thread on the inner wall of the adjusting ring 31. The adjusting ring 31 is threadedly connected to the connecting plate 321. When the adjusting ring 31 is rotated, the connecting plate 321 drives the female magnetic chuck 103 to move away from the male magnetic chuck 203 along the axis of the female housing 101 through the threaded transmission, thereby reducing the magnetic attraction between the female magnetic chuck 103 and the male magnetic chuck 203, making it easier to separate the female assembly 10 and the male assembly 20.

[0047] Furthermore, combined Figures 5-14As shown, the linkage unit further includes a third annular groove 323 disposed on the mating end face of the female end housing 101, an annular plate 324 slidably connected to the third annular groove 323, and a movable plate 325 corresponding to the connecting plate 321. The third annular groove 323 is coaxially disposed with the female end housing 101, and is located between the second annular groove 1012 and the outer wall of the female end housing 101, and is spaced apart from the first sliding groove 322. The movable plate 325 is disposed in a one-to-one correspondence with the connecting plate 321, and is disposed parallel to the axis of the female end housing 101. The connecting plate 321 is provided with a first through groove 3211 that slidably engages with the movable plate 325. One end of the movable plate 325 is fixedly connected to the annular plate 324, and the other end of the movable plate 325 extends into the first sliding groove 322 and is inserted into the first through groove 3211. The radial dimension of the movable plate 325 along the female end housing 101 is the thickness dimension of the movable plate 325. The radial dimension of the first through groove 3211 along the female end housing 101 is the height dimension of the first through groove 3211. The height dimension of the first through groove 3211 is greater than the maximum thickness dimension of the movable plate 325. The surface of the movable plate 325 near the axis of the female end housing 101 is a flat surface. The movable plate 325 has a first thick section 3251 and a second thick section 3252 with increasing thickness in sequence along the direction near the annular plate 324. Furthermore, on the surface of the movable plate 325 away from the axis of the female end housing 101, a... The first thick section 3251 has a first step surface 3253 corresponding to the first thick section 3251 and a second step surface 3254 corresponding to the second thick section 3252. A transition slope 3255 is provided between the first step surface 3253 and the second step surface 3254. The inclination angle of the transition slope 3255 is less than 45 degrees so that when the moving plate 325 moves, the connecting plate 321 is forced to move radially along the female end housing 101 through the transition slope 3255. For example, the inclination angle of the transition slope 3255 can be set to 30 degrees or 25 degrees. The corresponding inner wall of the first through groove 3211 is provided with a slope that cooperates with the transition slope 3255. A spring plate 326 is provided on the inner wall of the first through groove 3211 near the axis of the female end housing 101. The spring plate 326 is arranged along the length direction of the moving plate 325. One end of the spring plate 326 is fixedly connected to the inner wall of the first through groove 3211, and the other end is a free end. The spring plate 326 contacts the surface of the moving plate 325 near the axis of the female end housing 101 to force the connecting plate 321 to move in the direction of the axis of the female end housing 101.When the movable plate 325 moves to make the first stepped surface 3253 fit against the inner wall of the first through groove 3211, the upper end face of the connecting plate 321 is spaced apart from the inner wall of the adjusting ring 31. When the movable plate 325 moves to make the second stepped surface 3254 fit against the inner wall of the first through groove 3211, the external thread on the upper end face of the connecting plate 321 engages with the internal thread on the inner wall of the adjusting ring 31. The connecting plate 321 can only slide within the first sliding groove 322 in the radial direction of the female end housing 101 and in a direction parallel to the axis of the female end housing 101.

[0048] A connecting block 327 corresponding to the connecting plate 321 is fixedly provided on the inner end face of the female magnetic accumulator 103. The connecting block 327 is provided with a second through groove 3271 that slides with the connecting plate 321. The lower end of the connecting plate 321 is inserted into the second through groove 3271. A first spring 331 is provided in the second annular groove 1012 to force the female magnetic accumulator 103 to move closer to the male end assembly 20. Specifically, the first spring 331 is arranged parallel to the axis of the female end housing 101. One end of the first spring 331 contacts the bottom wall of the second annular groove 1012, and the other end of the first spring 331 is fixedly connected to the inner end face of the female magnetic accumulator 103. A second spring 332 is provided within the third annular groove 323 to force the annular plate 324 to move closer to the male end assembly 20. The second spring 332 is arranged parallel to the axis of the female end housing 101. One end of the second spring 332 is fixedly connected to the bottom wall of the third annular groove 323, and the other end of the second spring 332 is fixedly connected to the annular plate 324. Both the first spring 331 and the second spring 332 are compression springs.

[0049] Two positioning pins 333 are provided on the end face of the annular plate 324 near the male end housing. The two positioning pins 333 are asymmetrically distributed with respect to the axis of the annular plate 324. The mating end face of the male end housing 201 is provided with positioning pin holes 2012 that cooperate with the positioning pins 333. The positioning pins 333 are fixedly connected to the annular plate 324. The positioning pins 333 are beveled pins to facilitate insertion into the positioning pin holes 2012. The axis of the positioning pins 333 is parallel to the axis of the female end housing 101. The asymmetrical arrangement serves to prevent mistaken insertion. When the two positioning pins 333 are aligned with the two positioning pin holes 2012, the elastic contact pin is aligned with the female end pin. After the two positioning pins 333 are inserted into the positioning pin holes 2012, it can prevent the female end housing 101 from rotating relative to the male end housing 201 around its own axis, thus avoiding the female end pin from disengaging from the elastic contact pin on the male end housing 201 during use.

[0050] Understandably, in specific implementations, the elastic force of the first spring 331 needs to be such that, during the process of the moving plate 325 moving and causing the connecting plate 321 to slide into contact with the inner wall of the adjusting ring 31, the connecting plate 321 does not move away from the male end. That is, the elastic force of the first spring 331 is only used to reset the female end magnetic chuck 103 and prevent the moving plate 325 from pushing the connecting plate 321 away from the male end housing 101 when it moves, without affecting the rotation of the adjusting ring 31 to make the connecting plate 321 drive the female end magnetic chuck 103 to slide. The elastic force of the spring plate 326 is also only sufficient to force the connecting plate 321 to move towards the axis of the female end housing so that the inner wall of the first through groove 3211 is in contact with the first step surface 3253 or the second step surface 3254 of the moving plate 325, and has little effect on the movement of the moving plate 325 driving the connecting plate 321 to slide. In this design, the inner wall of the adjusting ring 31 has an internal thread section and a non-threaded section. The internal thread section is located near the male end assembly 20. On the inner wall of the adjusting ring 31, the inner diameter of the non-threaded section is smaller than the inner diameter of the internal thread section. When the adjusting ring 31 is turned to move the connecting plate 321 to the non-threaded section under the threaded drive, the adjusting ring 31 can no longer be turned to drive the connecting plate 321 to move. The maximum distance that the connecting plate 321 can move along the axis of the female end housing 101 when the adjusting ring 31 is turned can be limited by setting the length of the internal thread section on the inner wall of the adjusting ring 31.

[0051] When using this embodiment, in conjunction with Figures 10-13 As shown, when the male end assembly 20 is not mated with the female end assembly 10, under the elastic force of the second spring 332, the outer end of the annular plate 324 extends beyond the mating end face of the female end housing. At this time, the first stepped surface 3253 is located in the first groove 322 near the third annular groove 323, while the connecting plate 321, under the elastic force of the first spring 331, is located in contact with the side wall of the first groove 322 and cannot move further towards the mating end face of the female end housing 101. The female end magnetic chuck 103 is also located at the position closest to the male end magnetic chuck 203. At this time, the first stepped surface 3253... 53 is located at the position corresponding to the first through groove 3211 of the connecting plate 321. The thickness of the moving plate 325 at the first step surface 3253 is less than the thickness of the moving plate 325 at the second step surface 3254. Therefore, under the elastic force of the spring plate 326, the connecting plate 321 slides towards the axis of the female end housing 101. As a result, the external thread on the upper end surface of the connecting plate 321 and the internal thread on the inner wall of the adjusting ring 31 disengage from each other. At this time, rotating the adjusting ring 31 will not cause the connecting plate 321 to drive the female end magnetic accumulator 103 to move away from the male end assembly 20.

[0052] When the female end assembly 10 is mated with the male end assembly 20, the two positioning pins 333 on the female end housing 101 are aligned with the two positioning pin holes 2012 on the male end housing, and force is applied along the axial direction to bring the female end housing 101 and the male end housing 201 closer together. This causes the female end magnetic accumulator 103 and the male end magnetic accumulator 203 to come closer together and generate magnetic attraction, attracting each other and causing the female end housing 101 to press against the male end housing 201. At this time, the elastically expandable male end 202 and the female end 102 are in close contact to transmit electrical signals. During the process of the male end housing 201 moving to contact the female end housing 101, the annular plate 324 is pressed and slid back into the third annular groove 323 by the male end housing 201, thereby causing the moving plate 325 to move away from the male end housing 201 so that the second step surface 3254 is located at the position corresponding to the first through groove 3211 on the connecting plate 321. Figures 5-7 As shown, due to the increased thickness of the moving plate 325 at the second step surface 3254, the connecting plate 321 is forced to slide away from the axis of the female end housing 101 so that the external thread on the first end face of the connecting plate 321 engages with the internal thread on the inner wall of the adjusting ring 31.

[0053] When it is necessary to separate the female component 10 from the male component 20, combine Figure 15 , Figure 16 As shown, manually rotating the adjusting ring 31 causes each connecting plate 321 to move synchronously from different positions to the female magnetic chuck 103 away from the male housing 201 via threaded transmission. This increases the distance between the female magnetic chuck 103 and the male magnetic chuck 203. Since the magnetic attraction between magnets is inversely proportional to the square of the distance, as the distance between the female magnetic chuck 103 and the male magnetic chuck 203 increases, the magnetic attraction between them decreases rapidly and non-linearly, making it easy to separate the female assembly 10 and the male assembly 20. After the female end assembly 10 separates from the male end assembly 20, with the cooperation of the first spring 331, the second spring 332 and the spring plate 326, the outer end of the annular plate 324 extends out of the female end housing 101 again, the female end magnetic suction member 103 is once again in the initial position closest to the male end assembly 20, and the connecting plate 321 is once again in the initial position of disengaging from the adjusting ring 31, so that the aforementioned actions and functions can be repeated when docking and separating for the next time.
