[0026] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 7 As shown, the generator junction box includes: a box body 1, a fixing clamping plate 6 and a sliding seat 11,

[0028] Guide columns 3 are fixedly connected to both sides of the box body 1, and wiring holes 7 are respectively opened on both sides of the box body 1. The guide columns 3 are threadedly connected to sealing caps 4 at the side ends away from the box body 1. When the box body 1 is installed with cables, the sealing caps 4 are threadedly connected to the guide columns 3. The sealing caps 4 seal the wiring holes 7 opened on both sides of the box body 1 to prevent dust and moisture from entering the interior of the box body 1 from the wiring holes 7 and causing harm to the interior of the box body 1. The guide columns 3 have a bearing connection function for the sealing caps 4, and at the same time, the guide columns 3 have a guiding function for the cables; it also includes:

[0029] The fixed clamping plate 6 is fixedly connected to the inner wall of the box body 1, and the upper and lower ends of the fixed clamping plate 6 are provided with slide grooves 8. When the cable enters the box body 1, the fixed clamping plate 6 has a sealing effect on the cable. At the same time, the slide grooves 8 provided on the fixed clamping plate 6 have a supporting and limiting function; and

[0030] Two groups of slides 11 are arranged, and the slides 11 are slidably connected with the slide grooves 8. The two groups of slides 11 are fixedly connected with movable splints 16 on opposite sides. The slides 11 have the function of a connecting structure. The slides 11 transfer the supporting and limiting effect of the slide grooves 8 to the movable splints 16, ensuring that the movable splints 16 will not deviate, thereby ensuring the stability of the structure of the movable splints 16. The movable splints 16 support and seal the cables.

[0031] In some specific implementation schemes, a sealing groove 14 is provided at the side end of the guide column 3 away from the box body 1, a rounded corner 15 is provided on the inner wall of the side end of the guide column 3 away from the box body 1, the center line of the guide column 3 coincides with the center line of the wiring hole 7, and a sealing ring 13 is fixedly connected to the inner wall of the sealing cap 4. When the cable is installed in the box body 1, the center line of the guide column 3 coincides with the center line of the wiring hole 7 to ensure that the cable passes through the guide column 3, and the cable enters the box body 1 from the wiring hole 7. The guide column 3 provides limited support for the cable, and the rounded corner 15 makes it easy for the cable to enter the guide column 3. At the same time, it avoids damage to the cable by the side end of the guide column 3.

[0032] In some specific embodiments, the sealing ring 13 is rotatably connected to the sealing groove 14 , and the sealing ring 13 further seals the guide column 3 , thereby strengthening the sealing effect of the sealing cap 4 .

[0033] In some specific embodiments, the slide groove 8 is fixedly connected with a positioning rod 9 and a spring 10 at the side end away from the slide seat 11. The spring 10 is sleeved and connected to the positioning rod 9. The side end of the spring 10 away from the fixed splint 6 is fixedly connected to the slide seat 11. The spring 10 provides a pulling force to the slide seat 11. The spring 10 pulls the slide seat 11 to slide in the slide groove 8, and the slide seat 11 drives the movable splint 16 to move. The pulling force provided by the slide seat 11 is transmitted to the movable splint 16. When the movable splint 16 resists the cable, the cable is subjected to force and is in close contact with the movable splint 16 and the fixed splint 6, thereby ensuring that the gap between the cable and the wiring hole 7 is blocked, preventing dust and moisture from entering the interior of the box body 1, thereby ensuring the stable operation of the cable and the box body 1.

[0034] In some specific embodiments, the slide seat 11 is provided with a positioning hole 12 which passes through the slide seat 11 in a direction parallel to the center line of the positioning rod 9. The positioning hole 12 is slidably connected to the positioning rod 9. The positioning rod 9 transmits the supporting and guiding function of the positioning rod 9 to the movable splint 16 through the sliding connection with the positioning hole 12.

[0035] In some specific implementation schemes, a sliding hole 19 is opened at the side end of the box body 1 away from the fixed clamping plate 6, and the top of the box body 1 is detachably connected to the box cover 2. A control rod 5 is slidably connected in the sliding hole 19. The control rod 5 is fixedly connected to the movable clamping plate 16 at the side end close to the fixed clamping plate 6. The control rod 5 is threadedly connected to an adjusting nut 18 at the side end away from the fixed clamping plate 6. The adjusting nut 18 is fixedly connected to a sealing gasket 17 at the side end close to the box body 1. The sealing gasket 17 is in a circular ring shape and is abutted against the box body 1. The control rod 5 realizes the convenience of controlling and adjusting the movable clamping plate 16 inside the box body 1. When the cable is installed After that, the control rod 5 is controlled to move toward the inside of the box body 1, and the control rod 5 drives the movable clamping plate 16 to further support the cable to ensure that the movable clamping plate 16 and the cable are more tightly supported, and the adjusting nut 18 is rotated, and the adjusting nut 18 drives the sealing gasket 17 to rotate. When the sealing gasket 17 is against the side end of the box body 1, the rotation of the adjusting nut 18 is stopped, and the adjusting nut 18 fixes the control rod 5, thereby preventing the vibration generated by the operation of the generator from causing the movable clamping plate 16 to loosen, and the sealing gasket 17 seals the gap between the sliding hole 19 and the control rod 5, thereby ensuring the overall sealing of the box body 1.

[0036] In order for those skilled in the art to better understand the working principle of the embodiments of the present invention, the following is an explanation in conjunction with specific application scenarios:

[0037] When the box body 1 is not installed with cables, the sealing cap 4 is threadedly connected to the guide column 3, and the sealing cap 4 seals the wiring holes 7 opened on both sides of the box body 1 to prevent dust and moisture from entering the interior of the box body 1 through the wiring holes 7 and causing damage to the interior of the box body 1. The sealing ring 13 further seals the guide column 3, thereby strengthening the sealing effect of the sealing cap 4. When the box body 1 is installed with cables, the sealing cap 4 is rotated and removed, and the cable passes through the wiring hole 7 along the inner wall of the guide column 3. When the cable is connected to the wiring terminal inside the box body 1, the adjusting nut 18 is rotated, and the adjusting nut 18 drives the sealing gasket 17 to rotate, and the adjusting nut 18 drives the sealing gasket 17 to move away from the box body 1. The spring 10 pulls the slide 11 to move in the slide groove 8, and the slide 11 drives the moving clamp 16 to move. The plate 16 holds the cable, and the pulling force provided by the spring 10 is transmitted to the movable clamping plate 16, and the movable clamping plate 16 tightly holds the cable, and the control rod 5 is controlled to move toward the inner direction of the box body 1, and the control rod 5 drives the movable clamping plate 16 to further apply a holding force to the cable, and the adjusting nut 18 is rotated, and the adjusting nut 18 drives the sealing gasket 17 to move toward the direction close to the box body 1. When the sealing gasket 17 and the box body 1 are in contact, the rotation of the adjusting nut 18 is stopped. After the cable is subjected to the holding force, the cable is in close contact with the fixed clamping plate 6 and the movable clamping plate 16 respectively, and the fixed clamping plate 6 and the movable clamping plate 16 avoid gaps with the cable, and at the same time, the gaps between the wiring hole 7 and the cable are blocked, thereby preventing dust and moisture from entering the interior of the box body 1 through the gaps, thereby ensuring the normal operation of the box body 1 and the cable;

[0038] Among them, the guide column 3 has a guiding function for the cable, and the rounded corner 15 makes it easy for the cable to enter the guide column 3. At the same time, it avoids the side end of the guide column 3 from causing damage to the cable. The slide 11 has the function of a connecting structure. The slide 11 transfers the supporting and limiting function of the slide groove 8 to the movable splint 16, ensuring that the movable splint 16 will not be offset, thereby ensuring the stability of the structure of the movable splint 16. The positioning rod 9 transfers the supporting and guiding function of the positioning rod 9 to the movable splint 16 through a sliding connection with the positioning hole 12.

[0039] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
