The inner side of the plug 1 is matched with the inner side of the socket 2, and the plurality of sleeves 3 on the inner side of the plug 1 are respectively matched with the plurality of plug cores 4 on the inner side of the socket 2, until the sleeve 3 is correspondingly sleeved on the surface of the plug core 4, and the inner core inside the sleeve 3 is plugged into the inner side of the plug core 4, and the electrical connection between the plug 1 and the socket 2 is completed. After the sleeve frame 3 and the insert core 4 are plugged in, the screw 6 is turned, and the inner end of the rotating screw 6 is spirally plugged into the inner side of the fixed head 5. At this time, the rotating screw 6 drives the socket 2 close to the plug 1 until the inner side of the side surface of the screw 6 fits with the inner side of the fixed head 5, completing the connection between the plug 1 and the socket 2.

[0018] exist Figure 1 , Figure 3 and Figure 4 In the figure, the positioning component includes two opposite arc frames 7, which are installed on the inner side of the plug 1. The inner side of the socket 2 is fixed with a plug rod 8 inserted between the two arc frames 7. The inner concave surface of the arc frame 7 fits with the outer circumferential surface of the plug rod 8. A square plate 9 is fixed to the inner side of the plug rod 8. A screw 10 passes through the surface of the plug 1, and the inner end of the screw 10 is spirally inserted in the center of the inner side of the square plate 9. By utilizing the spiral cooperation of the screw rod 6 and the fixed head 5, when the socket 2 is close to the plug 1, the socket 2 drives the plug rod 8 to enter between the two arc frames 7. At this time, the inner concave surface of the arc frame 7 fits on the surface of the plug rod 8. At this time, the plug rod 8 drives the square plate 9 close to the inner side of the plug 1. The spiral cooperation of the screw rod 6 and the fixed head 5 defines the plug 1 and the socket 2. The screw 10 is passed through the plug 1, and the screw 10 is rotated. The inner end of the screw 10 is spirally inserted in the center of the square plate 9. The spiral cooperation of the screw 10 and the square plate 9 is utilized to further define the plug 1 and the socket 2, thereby ensuring the connection stability of the plug 1 and the socket 2 and avoiding the separation of the plug 1 and the socket 2 due to simple pulling.

[0019] exist Figures 4 to 7In the embodiment, an inner rod 11 is fixed at the center of the arc frame 7, a slip ring 12 is sleeved on the surface of the inner rod 11, two cross bars 13 are fixed on the outer side of the circumference of the slip ring 12, and inner grooves 14 are provided on both inner sides of the arc frame 7. When the slip ring 12 slides on the surface of the inner rod 11, the moving slip ring 12 drives the end of the cross bar 13 to move inside the inner groove 14. The outer side of the slip ring 12 is connected to the inner side 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 of the slip ring 12, and the inner side of the plug rod 8 is correspondingly fitted with the inner side of the limiting block 16. The plug rod 8 pushes the slip 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 plug rod 8 contacts the inner side face of the limiting block 16, the plug rod 8 uses the limiting block 16 to drive the slip ring 12 to slide on the surface of the inner rod 11, and the slip ring 12 approaches the plug 1 during the movement, and the moving slip ring 12 cooperates with the plug 1 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 plug rod 8 on the limiting block 16, thereby preventing the limiting block 16 from driving the slip ring 12 to directly impact the inner side face of the plug 1 under the action of the impact force, thereby facilitating the protection of the slip ring 12.

[0020] exist Figures 5 to 7 In the figure, the surfaces of the two cross bars 13 are sleeved with swivels 17, the two swivels 17 are arranged opposite to each other, and the outer side of the circumferential outer side surface of the swivel 17 is annularly arranged with teeth 18, and the two inner side walls of the arc frame 7 are fixed with racks 19, and the swivels 17 are meshed with the racks 19 by the teeth 18, and the surface of the cross bar 13 is provided with an annular groove, and the inner side wall of the swivel 17 is connected to the circumferential outer side surface of the annular groove by multiple pull tabs 20, and the pull tabs 20 are made of elastic material. When the slip ring 12 is close to the inner side of the plug 1, the slip ring 12 drives the cross bar 13 to move inside the inner groove 14, and the moving cross bar 13 drives the swivel 17 to move synchronously. Since the rack 19 is meshed with the teeth 18, the moving swivel 17 rotates on the top of the rack 19 using the teeth 18. The inner side of the rotating swivel 17 pulls the pull tab 20, and the deformed pull tab 20 is wrapped around the outer side of the circumference of the annular groove. The twisting force of multiple pull tabs 20 further absorbs the impact force of the plug rod 8 on the limiting block 16.

[0021] exist Figure 4 , Figure 6 and Figure 7In the embodiment, a rotating plate 21 is fixed to the outer side of the circumference of the rotating ring 17. When the moving crossbar 13 drives the rotating ring 17 to move, due to the meshing cooperation between the teeth 18 and the rack 19, the moving rotating ring 17 rotates on the top of the rack 19, and the rotating rotating ring 17 drives the rotating plate 21 to rotate, and the outer end of the rotating plate 21 cooperates and squeezes on the side of the square plate 9. 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 process, and the outer end of the rotating plate 21 at the top gradually fits on the top surface of the square plate 9, and the outer end of the rotating plate 21 at the bottom 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, and preventing the inner side of the square plate 9 from impacting the inner side of the plug 1. The clamping of the square plate 9 by the upper and lower rotating plates 21 further improves the connection stability between the plug 1 and the socket 2.

[0022] exist Figure 4 , Figure 5 and Figure 8 In the embodiment, two slide bars 22 are inserted into the inner end of the arc frame 7, and the inner end of the slide bar 22 is located outside the arc frame 7. A sleeve 23 is fixed to the inner end of the two slide bars 22, and the sleeve 23 is sleeved on the surface of the inner rod 11. A convex head 24 corresponding to the slip ring 12 is fixed to the outer side of the sleeve 23. The outer side of the sleeve 23 is connected to the end face of the arc frame 7 by a second spring 25, and the second spring 25 is sleeved on the surface of the inner rod 11. A card 26 corresponding to the inner end of the slide bar 22 is fixed to the inner end face of the arc frame 7, and a rotating sleeve 27 is rotatably sleeved on the outer side of the card 26, and the rotating sleeve 27 is spirally sleeved on the inner end surface of the slide bar 22. Twist the rotating sleeve 27. Since the arc frame 7 uses the card 26 to limit the rotating sleeve 27, the rotating sleeve 27 rotates on the inner end surface of the slide rod 22. The sleeve plate 23 and the inner rod 11 cooperate to limit the two slide rods 22. The rotating rotating sleeve 27 enables the slide rod 22 to drive the sleeve plate 23 to move on the surface of the inner rod 11.

[0023] When the sleeve 23 approaches the slip ring 12, until the end face of the protrusion 24 contacts the inner side of the slip ring 12, the moving sleeve 23 uses the protrusion 24 to drive the slip ring 12 to move, and through the spiral cooperation between the rotating sleeve 27 and the sliding rod 22, it is convenient to adjust the relative distance between the slip ring 12 and the plug 1 under the elastic force of the first spring 15, so that the two arc frames 7 of the plug 1 can adapt to the plug rods 8 of different lengths.

[0024] The present invention further provides a precision cabinet connector assembly, which is composed of the above-mentioned plug 1 and a socket 2 that can be engaged with the plug 1.

[0025] Working principle of the present invention: Reference 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 sleeves 3 on the inner side of the plug 1 are respectively matched with the multiple plug cores 4 on the inner side of the socket 2 until the sleeve 3 is correspondingly sleeved on the surface of the plug core 4. At this time, the inner core of the sleeve 3 is inserted into the inner side of the plug core 4, completing the electrical connection between the plug 1 and the socket 2. After the sleeve 3 and the plug core 4 are matched and inserted, the screw 6 is turned, and the inner side end of the rotating screw 6 is spirally inserted into the inner side of the fixed head 5. At this time, the rotating screw 6 drives the socket 2 to approach the plug 1 until the inner side of the side edge of the screw 6 surface is in contact with the inner side of the fixed head 5, completing the connection between the plug 1 and the socket 2.

[0026] By utilizing the spiral cooperation of the screw rod 6 and the fixed head 5, when the socket 2 is close to the plug 1, the socket 2 drives the plug rod 8 to enter between the two arc frames 7. At this time, the inner concave surface of the arc frame 7 fits on the surface of the plug rod 8. At this time, the plug rod 8 drives the square plate 9 close to the inner side of the plug 1. The spiral cooperation of the screw rod 6 and the fixed head 5 defines the plug 1 and the socket 2. The screw 10 is passed through the plug 1, and the screw 10 is rotated. The inner end of the screw 10 is spirally inserted in the center of the square plate 9. The spiral cooperation of the screw 10 and the square plate 9 is utilized to further define the plug 1 and the socket 2, thereby ensuring the connection stability of the plug 1 and the socket 2 and avoiding the separation of the plug 1 and the socket 2 due to simple pulling.

[0027] When the inner end face of the moving plug rod 8 contacts the inner side face of the limiting block 16, the plug rod 8 drives the slip ring 12 to slide on the surface of the inner rod 11 by means of the limiting block 16, and the slip ring 12 approaches the plug 1 during the movement, and the moving slip ring 12 cooperates with the plug 1 to squeeze the first spring 15 on the surface of the inner rod 11, and the impact force of the plug rod 8 on the limiting block 16 is absorbed by the elastic force of the first spring 15. When the slip ring 12 approaches the inner side face of the plug 1, the slip ring 12 drives the cross bar 13 to move inside the inner groove 14, and the moving cross bar 13 drives the rotating ring 17 to move synchronously. Since the rack 19 is meshed with the teeth 18, the moving rotating ring 17 rotates on the top of the rack 19 by means of the teeth 18, and the inner side face of the rotating rotating ring 17 pulls the pull tab 20, and the deformed pull tab 20 is wound around the outer side face of the circumference of the annular groove. The 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 process. The outer end of the top rotating plate 21 gradually fits against the top surface of the square plate 9, and the outer end of the bottom rotating plate 21 gradually fits against 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. The clamping of the square plate 9 by the upper and lower rotating plates 21 further improves the connection stability between the plug 1 and the socket 2.

[0028] Twist the rotating sleeve 27. Since the arc frame 7 uses the card 26 to limit the rotating sleeve 27, the rotating sleeve 27 rotates on the inner end surface of the slide rod 22. The sleeve plate 23 and the inner rod 11 cooperate to limit the two slide rods 22. The rotating rotating sleeve 27 enables the slide rod 22 to drive the sleeve plate 23 to move on the surface of the inner rod 11.

[0029] When the sleeve 23 approaches the slip ring 12, until the end face of the protrusion 24 contacts the inner side of the slip ring 12, the moving sleeve 23 uses the protrusion 24 to drive the slip ring 12 to move, and through the spiral cooperation between the rotating sleeve 27 and the sliding rod 22, it is convenient to adjust the relative distance between the slip ring 12 and the plug 1 under the elastic force of the first spring 15, so that the two arc frames 7 of the plug 1 can adapt to the plug rods 8 of different lengths.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
