[0026] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0027] The present invention provides a precision cabinet connector, as Figures 1 to 3As shown, it includes a plug 1 and a socket 2. The plug 1 and the socket 2 are arranged opposite to each other. A plurality of sleeve frames 3 are provided on the inner side of the plug 1, and a plurality of cores 4 are provided on the inner side of the socket 2. The plurality of sleeve frames 3 correspond to the plurality of cores 4 one by one. Positioning components and fixing components are respectively provided on both sides of the corresponding surfaces of the plug 1 and the socket 2. The fixing component includes a fixing head 5. The fixing head 5 is installed on the inner side of the plug 1. A screw rod 6 is rotatably inserted into the end face of the socket 2, and the inner end of the screw rod 6 is spirally inserted into the inner side of the fixing head 5. A side edge is fixed on the surface of the screw rod 6, and the inner side of the side edge is attached to the inner side of the fixing head 5. Align the inner side of the plug 1 with the inner side of the socket 2. At this time, the plurality of sleeve frames 3 on the inner side of the plug 1 cooperate with the plurality of cores 4 on the inner side of the socket 2 respectively until the sleeve frames 3 are correspondingly sleeved on the surface of the cores 4. At this time, the inner core inside the sleeve frame 3 is inserted into the inside of the core 4, completing the electrical connection between the plug 1 and the socket 2. After the sleeve frames 3 and the cores 4 are cooperatively inserted, turn the screw rod 6. The rotating inner end of the screw rod 6 is spirally inserted into the inner side of the fixing head 5. At this time, the rotating screw rod 6 drives the socket 2 to approach the plug 1 until the inner side of the side edge on the surface of the screw rod 6 is attached to the inner side of the fixing head 5, completing the connection between the plug 1 and the socket 2.

[0028] In Figure 1 , Figure 3 and Figure 4 , the positioning component includes two opposite arc-shaped frames 7. The arc-shaped frames 7 are installed on the inner side of the plug 1. A plugging rod 8 inserted between the two arc-shaped frames 7 is fixed on the inner side of the socket 2. The concave surface of the arc-shaped frame 7 is attached to the circumferential outer side surface of the plugging rod 8. A square plate 9 is fixed on the inner side of the plugging rod 8. A screw 10 penetrates through the surface of the plug 1, and the inner end of the screw 10 is spirally inserted into the center of the inner side of the square plate 9. When the socket 2 is driven by the screw 6 and the fixing head 5 to approach the plug 1 by means of the spiral cooperation, the socket 2 drives the plugging rod 8 to enter between the two arc-shaped frames 7. At this time, the concave surface of the arc-shaped frame 7 is attached to the surface of the plugging rod 8. At this time, the plugging rod 8 drives the square plate 9 to approach the inner side of the plug 1. The spiral cooperation between the screw 6 and the fixing head 5 limits the plug 1 and the socket 2. Pass the screw 10 through the plug 1 and turn the screw 10. The inner end of the screw 10 is spirally inserted into the center of the square plate 9. The spiral cooperation between the screw 10 and the square plate 9 further limits the plug 1 and the socket 2, ensuring the connection stability between the plug 1 and the socket 2 and preventing the plug 1 and the socket 2 from separating due to simple pulling.

[0029] In Figures 4 to 7In it, an inner rod 11 is fixed at the center of the arc-shaped frame 7. A sliding ring 12 is sleeved on the surface of the inner rod 11. Two cross bars 13 are fixed on the circumferential outer side surface of the sliding ring 12. Inner grooves 14 are arranged on both inner side surfaces of the arc-shaped frame 7. When the sliding ring 12 slides on the surface of the inner rod 11, the moving sliding ring 12 drives the ends of the cross bars 13 to move inside the inner grooves 14. The outer side surface of the sliding ring 12 is connected to the inner side surface of the plug 1 by a first spring 15, and the first spring 15 is sleeved on the surface of the inner rod 11. A limiting block 16 is fixed on the inner side part of the sliding ring 12. The inner side surface of the insertion rod 8 corresponds to and fits with the inner side surface of the limiting block 16. The insertion rod 8 pushes the sliding ring 12 to slide on the surface of the inner rod 11 through the limiting block 16. When the inner end face of the moving insertion rod 8 contacts the inner side surface of the limiting block 16, the insertion rod 8 drives the sliding ring 12 to slide on the surface of the inner rod 11 by means of the limiting block 16, and the sliding ring 12 approaches the plug 1 during the movement. The moving sliding ring 12 and the plug 1 cooperate to squeeze the first spring 15 on the surface of the inner rod 11. The elastic force of the first spring 15 absorbs the impact force of the insertion rod 8 on the limiting block 16, avoiding the limiting block 16 driving the sliding ring 12 to directly impact the inner side surface of the plug 1 under the action of the impact force, which is convenient for protecting the sliding ring 12.

[0030] In Figures 5 to 7 it, swivel rings 17 are sleeved on the surfaces of both cross bars 13. The two swivel rings 17 are arranged oppositely. Tooth teeth 18 are annularly arranged on the outer side part of the circumferential outer side surface of the swivel ring 17. Rack bars 19 are fixed on both inner side walls of the arc-shaped frame 7, and the swivel ring 17 is meshed with the rack bar 19 by means of the tooth teeth 18. A ring groove is arranged on the surface of the cross bar 13. The inner side wall of the swivel ring 17 is connected to the circumferential outer side surface of the ring groove by a plurality of pulling pieces 20, and the pulling pieces 20 are made of elastic materials. When the sliding ring 12 approaches the inner side surface of the plug 1 and the sliding ring 12 drives the cross bar 13 to move inside the inner groove 14, the moving cross bar 13 drives the swivel ring 17 to move synchronously. Due to the meshing of the rack bar 19 and the tooth teeth 18, the moving swivel ring 17 rotates on the top of the rack bar 19 by means of the tooth teeth 18. The inner side surface of the rotating swivel ring 17 pulls the pulling piece 20, and the deformed pulling piece 20 winds around the circumferential outer side surface of the ring groove. The impact force of the insertion rod 8 on the limiting block 16 is further absorbed by the twisting force of the plurality of pulling pieces 20.

[0031] In Figure 4 、 Figure 6 and Figure 7In it, a rotating plate 21 is fixed on the outer circumferential side surface of the swivel ring 17. When the moving cross bar 13 drives the swivel ring 17 to move, due to the meshing cooperation between the teeth 18 and the rack 19, the moving swivel ring 17 rotates on the top of the rack 19. The rotating swivel ring 17 drives the rotating plate 21 to rotate, and the outer side end of the rotating plate 21 is cooperatively pressed against the side surface of the square plate 9. The rotating swivel ring 17 drives the rotating plate 21 to rotate synchronously. At this time, the outer side end of the rotating plate 21 gradually approaches the square plate 9 during the rotation process. The outer side end of the top rotating plate 21 gradually adheres to the top surface of the square plate 9, and the outer side end of the bottom rotating plate 21 gradually adheres to the bottom surface of the square plate 9, preventing the square plate 9 from continuing to approach the inner side surface of the plug 1 and preventing the inner side surface of the square plate 9 from impacting the inner side surface of the plug 1. Moreover, the clamping of the upper and lower rotating plates 21 on the square plate 9 further improves the connection stability between the plug 1 and the socket 2.

[0032] In Figure 4 , Figure 5 and Figure 8 In it, two sliding rods 22 are inserted into the inner side end of the arc-shaped frame 7. The inner side ends of the sliding rods 22 are located outside the arc-shaped frame 7. A sleeve plate 23 is fixed to the inner side ends of the two sliding rods 22. The sleeve plate 23 is sleeved on the surface of the inner rod 11. A convex head 24 corresponding to the sliding ring 12 is fixed to the outer side surface of the sleeve plate 23. The outer side surface of the sleeve plate 23 is connected to the end surface of the arc-shaped frame 7 by a second spring 25. The second spring 25 is sleeved on the surface of the inner rod 11. A card 26 corresponding to the inner side end of the sliding rod 22 is fixed to the inner side end surface of the arc-shaped frame 7. A rotating sleeve 27 is rotatably sleeved on the outer side of the card 26. The rotating sleeve 27 is spirally sleeved on the surface of the inner side end of the sliding rod 22. When the rotating sleeve 27 is rotated, since the arc-shaped frame 7 limits the rotating sleeve 27 by the card 26, the rotating rotating sleeve 27 rotates on the surface of the inner side end of the sliding rod 22. With the cooperation of the sleeve plate 23 and the inner rod 11, the two sliding rods 22 are limited. The rotating rotating sleeve 27 causes the sliding rods 22 to drive the sleeve plate 23 to move on the surface of the inner rod 11.

[0033] When the sleeve plate 23 approaches the sliding ring 12 until the end surface of the convex head 24 contacts the inner side surface of the sliding ring 12, the moving sleeve plate 23 drives the sliding ring 12 to move by the convex head 24. Through the spiral cooperation between the rotating sleeve 27 and the sliding rod 22, it is convenient to adjust the relative distance between the sliding ring 12 and the plug 1 under the elastic limit of the first spring 15, and it is convenient for the two arc-shaped frames 7 of the plug 1 to adapt to plug-in rods 8 of different lengths.

[0034] The present invention also provides a precision cabinet connector assembly, which is composed of the above-mentioned plug 1 and a socket 2 that can be fitted with the plug 1.

[0035] The working principle of the present invention:

[0036] Referring to Figures 1 to 8As shown, the inner side of the plug 1 is aligned with the inner side of the socket 2. At this time, the multiple sleeve frames 3 on the inner side of the plug 1 are respectively engaged with the multiple cores 4 on the inner side of the socket 2 until the sleeve frames 3 are correspondingly sleeved on the surface of the cores 4. At this time, the inner cores inside the sleeve frames 3 are inserted into the inside of the cores 4, completing the electrical connection between the plug 1 and the socket 2. After the sleeve frames 3 and the cores 4 are engaged and inserted, turn the screw rod 6. The inner end of the rotating screw rod 6 is spirally inserted into the inner side of the fixed head 5. At this time, the rotating screw rod 6 drives the socket 2 to approach the plug 1 until the side inner side of the surface of the screw rod 6 fits with the inner side of the fixed head 5, completing the connection between the plug 1 and the socket 2.

[0037] When the socket 2 approaches the plug 1 by using the spiral fit between the screw rod 6 and the fixed head 5, the socket 2 drives the insertion rod 8 into the space between the two arc-shaped frames 7. At this time, the concave surface of the arc-shaped frame 7 fits on the surface of the insertion rod 8. At this time, the insertion rod 8 drives the square plate 9 to approach the inner side of the plug 1. The spiral fit between the screw rod 6 and the fixed head 5 limits the plug 1 and the socket 2. Pass the screw 10 through the plug 1 and turn the screw 10. The inner end of the screw 10 is spirally inserted into the center of the square plate 9. By using the spiral fit between the screw 10 and the square plate 9, the plug 1 and the socket 2 are further limited, ensuring the connection stability between the plug 1 and the socket 2 and preventing the plug 1 and the socket 2 from separating due to simple pulling.

[0038] When the inner end face of the moving insertion rod 8 contacts the inner side of the limiting block 16, the insertion rod 8 drives the sliding ring 12 to slide on the surface of the inner rod 11 by using the limiting block 16, and the sliding ring 12 approaches the plug 1 during the movement. The moving sliding ring 12 cooperates with the plug 1 to compress the first spring 15 on the surface of the inner rod 11, and the impact force of the insertion rod 8 on the limiting block 16 is absorbed by the elastic force of the first spring 15. When the sliding ring 12 approaches the inner side of the plug 1, when the sliding ring 12 drives the cross bar 13 to move inside the inner groove 14, the moving cross bar 13 drives the rotating ring 17 to move synchronously. Since the rack 19 meshes with the teeth 18, the moving rotating ring 17 rotates on the top of the rack 19 by using the teeth 18, and the inner side of the rotating rotating ring 17 pulls the pull tab 20, and the deformed pull tab 20 winds around the outer side of the circumferential surface of the ring groove. The rotating rotating ring 17 drives the rotating plate 21 to rotate synchronously. At this time, the outer end of the rotating plate 21 gradually approaches the square plate 9 during the rotation. The outer end of the top rotating plate 21 gradually fits on the top surface of the square plate 9, and the outer end of the bottom rotating plate 21 gradually fits on the bottom surface of the square plate 9, preventing the square plate 9 from continuing to approach the inner side of the plug 1, preventing the inner side of the square plate 9 from impacting the inner side of the plug 1, and the clamping of the upper and lower rotating plates 21 on the square plate 9 further improves the connection stability between the plug 1 and the socket 2.

[0039] Turn the rotating sleeve 27. Since the arc-shaped frame 7 limits the rotating sleeve 27 by using the card 26, the rotating rotating sleeve 27 rotates on the surface of the inner end of the sliding rod 22. With the cooperation of the sleeve plate 23 and the inner rod 11, the two sliding rods 22 are limited. The rotating rotating sleeve 27 causes the sliding rod 22 to drive the sleeve plate 23 to move on the surface of the inner rod 11.

[0040] When the template 23 approaches the slip ring 12 until the end face of the convex head 24 contacts the inner side face of the slip ring 12, the moving template 23 drives the slip ring 12 to move by means of the convex head 24. Through the screw fit between the rotating sleeve 27 and the slide bar 22, it is convenient to adjust the relative distance between the slip ring 12 and the plug 1 under the elastic limit of the first spring 15, so that the two arc-shaped frames 7 of the plug 1 can adapt to the plug rods 8 of different lengths.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
