The cable connecting part 1 is placed in the lower box body 3, and the fixed edges 4 of the upper box body 2 are aligned with the fixed edges 4 of the lower box body 3 and then bolts are inserted for installation, and auxiliary connectors 5 are provided on the two fixed edges 4 on one side.

[0040] The auxiliary connector 5 includes a U-shaped seat 51 fixedly connected along the lower fixed edge 4, and the inner side of the U-shaped seat 51 is rotatably connected to an inner shaft 52, a bracket 53 is fixedly connected to the inner shaft 52, and the outer end of the bracket 53 is fixedly connected to a dovetail block 54, and a dovetail groove 55 that cooperates with the dovetail block 54 is provided on the upper fixed edge 4. The upper box body 2 is passed through the dovetail groove 55 on the fixed edge 4 and the dovetail block 54 to the bottom. At this time, the upper box body 2 is pushed to make it deflected by the bracket 53. When the upper box body 2 and the lower box body 3 are in contact, the operator can install bolts along the bolt holes on the outer fixed edges 4 of the two to fix them.

[0041] An inner locking assembly 56 that matches the cable connecting portion 1 is provided on the upper box body 2 and the lower box body 3 .

[0042] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 9 As shown, the inner locking assembly 56 includes a torsion spring 561 movably sleeved on the inner shaft 52 , and a toothed disc 562 is rotatably connected to the inner shaft 52 , and two ends of the torsion spring 561 are respectively connected to the toothed disc 562 and the bracket 53 .

[0043] The inner side of the U-shaped seat 51 is slidably connected to the tooth seat 563, and a top spring 564 is provided in the U-shaped seat 51. The top spring 564 pushes the tooth seat 563 to engage and lock with the tooth disc 562. During the process of the upper box body 2 being deflected and combined by the bracket 53, the bracket 53 tightens the torsion spring 561, and the tooth seat 563 engages and locks with the tooth disc 562 so that the tooth disc 562 cannot rotate.

[0044] A ramp 565 is fixedly provided on the gear seat 563, and a bent plate 566 for squeezing the ramp 565 is provided on the bracket 53. When the upper box body 2 is attached to the lower box body 3, the two parts of the sealing sleeve 5614 and the two parts of the ring rail 5615 are combined into a closed ring structure. At the same time, the bent plate 566 on the bracket 53 squeezes the ramp 565, causing it to drive the gear seat 563 to leave the tooth disc 562 and release the lock. The tightened torsion spring 561 pushes the tooth disc 562 to rotate.

[0045] The inner side of the U-shaped seat 51 is rotatably connected to a first bevel gear 567 , and the outer ring of the first bevel gear 567 is provided with a ring gear 568 meshing with the gear plate 562 .

[0046] A notch 569 is provided on the inner wall of the lower box body 3, and a driving gear 5610 is rotatably connected in the notch 569. A second bevel gear 5611 is coaxially fixedly provided on the driving gear 5610. A connecting rod 5612 is rotatably provided inside the lower box body 3 and the U-shaped seat 51, and both ends of the connecting rod 5612 extend to the first bevel gear 567 and the second bevel gear 5611 respectively. Both ends of the connecting rod 5612 are fixedly connected to a transmission bevel gear 5613, and the transmission bevel gears 5613 at both ends are respectively engaged with the first bevel gear 567 and the second bevel gear 5611 for transmission.

[0047] A sealing sleeve 5614 is provided in the upper box body 2 and the lower box body 3, and the two parts of the sealing sleeve 5614 are configured as a semi-conical structure that can be combined with each other. The interiors of the upper box body 2 and the lower box body 3 are fixedly connected with semicircular ring rails 5615 with mutual cooperation. The two parts of the sealing sleeve 5614 are respectively slidably connected to the two ring rails 5615, and the side surfaces of the two parts of the sealing sleeve 5614 are fixedly connected with semicircular gear rings 5616 with mutual cooperation.

[0048] The driving gear 5610 is engaged with the lower gear ring 5616. The first bevel gear 567 engaged with the gear plate 562 drives the driving gear 5610 to rotate using the connecting rod 5612 and the transmission bevel gear 5613. The driving gear 5610 pushes the sealing sleeve 5614 combined into a circle along the gear ring 5616 to perform a circular motion along the annular track 5615 until the sealing sleeve 5614 is connected to the two parts of the annular track 5615 at the same time.

[0049] A cable gap filling component 5617 is provided on the sealing sleeve 5614.

[0050] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 9 As shown, the cable gap filling component 5617 includes a through groove 56171 opened along the surface of the sealing sleeve 5614, and the through groove 56171 passes through the inner and outer surfaces of the sealing sleeve 5614, and an air bag 56172 is provided in the through groove 56171.

[0051] An annular groove 56173 communicating with the through groove 56171 is defined on the outer surface of the sealing sleeve 5614 , and the airbag 56172 extends into the annular groove 56173 .

[0052] The upper box body 2 and the lower box body 3 are both fixedly provided with extrusion ribs 56174, and the number of extrusion ribs 56174 is symmetrically arranged in groups of two inside the upper box body 2 and the lower box body 3 respectively. The extrusion ribs 56174 are located in the annular groove 56173. When the upper box body 2 and the lower box body 3 are combined to deflect and lock the sealing sleeve 5614, the airbag 56172 on the sealing sleeve 5614 follows and performs a 90° circular motion, so that the extrusion rib 56174 squeezes the airbag 56172 along the annular groove 56173, so that the airbag 56172 expands into the sealing sleeve 5614 along the through groove 56171 and fills the gap between the cable connecting part 1 and the sealing sleeve 5614.

[0053] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 9 As shown, the dovetail groove 55 and the dovetail block 54 are fixedly provided with mutually cooperating magnetic blocks. When the upper box body 2 is inserted along the dovetail block 54 through the dovetail groove 55, the magnetic blocks between the two are magnetically positioned with each other, which on the one hand ensures that the insertion is in place, and on the other hand can provide a certain restraining force to avoid easy displacement.

[0054] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 9 As shown, the outer surfaces of the upper box body 2 and the lower box body 3 are provided with anti-slip grooves. When the user operates the upper box body 2 and the lower box body 3, the anti-slip grooves can increase the contact friction and ensure the stability of holding and installation.

[0055] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 9 As shown, the ring rail 5615 is set to a T-shaped structure, and the outer surface of the sealing sleeve 5614 is provided with a T-shaped track groove adapted to the ring rail 5615. The two parts of the sealing sleeve 5614 can perform circular motion along the ring rail 5615 combined into a closed ring structure through the track groove.

[0056] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 9 As shown, a sliding groove is provided on the inner side of the U-shaped seat 51 to match the tooth seat 563, and the tooth seat 563 is slidably connected along the sliding groove. The tooth seat 563 can only be displaced within a preset range along the sliding groove to ensure a stable fit between the tooth seat 563 and the bending plate 566 and the toothed disc 562.

[0057] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 9 As shown, a support ring is fixedly provided on the outer ring of the airbag 56172, and the support ring is fixed in the through groove 56171 by screws. The support ring does not affect the extrusion of the outer part of the airbag 56172 by the extrusion ridge 56174, nor does it affect the expansion of the inner part of the airbag 56172 into the sealing sleeve 5614. At the same time, it can provide a limit for the airbag 56172 to prevent it from improperly shifting in the through groove 56171.

[0058] The use method and advantages of the present invention: When the high-voltage cable terminal connection structure is in operation and use, the working process is as follows:

[0059] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 9 As shown:

[0060] S1. Place the cable connector 1 into the lower box body 3, and insert the upper box body 2 through the dovetail groove 55 on the fixed edge 4 and along the dovetail block 54 to the bottom. At this time, push the upper box body 2 to deflect it using the bracket 53. When the upper box body 2 and the lower box body 3 are in contact, the operator can install bolts along the bolt holes on the outer fixed edges 4 of the two to fix them.

[0061] S2. During the deflection and assembly of the upper box body 2 through the bracket 53, the bracket 53 tightens the torsion spring 561. When the upper box body 2 is attached to the lower box body 3, the two-part sealing sleeve 5614 and the two-part ring rail 5615 are combined into a closed ring structure. At the same time, the bent plate 566 on the bracket 53 squeezes the ramp 565, causing it to drive the gear seat 563 to leave the gear plate 562 and release the lock. The tightened torsion spring 561 pushes the gear plate 562 to rotate. The first bevel gear 567 engaged with the gear plate 562 drives the driving gear 5610 to rotate using the connecting rod 5612 and the transmission bevel gear 5613. The driving gear 5610 pushes the sealing sleeve 5614 combined into a circle to perform a circular motion along the ring rail 5615 along the gear ring 5616 until the sealing sleeve 5614 is simultaneously connected to the two-part ring rail 5615.

[0062] S3. The cable connection part 1 is located between the two sealing sleeves 5614. During the process of the upper box body 2 and the lower box body 3 being combined to deflect and lock the sealing sleeve 5614, the airbag 56172 on the sealing sleeve 5614 follows and performs a 90° circular motion, so that the extrusion edge 56174 squeezes the airbag 56172 along the annular groove 56173, so that the airbag 56172 expands along the through groove 56171 into the sealing sleeve 5614 and fills the gap between the cable connection part 1 and the sealing sleeve 5614.
