[0033] See attached document Figure 1-6 A photovoltaic power generation module junction box that is easy to install and disassemble includes:

[0034] Box 1, with a terminal block 2 at its front end; a sliding groove 3 is provided on the upper sides of both the front and rear walls of box 1, and a guide post 4 is provided in the sliding groove 3; a compression spring 5 is sleeved on the guide post 4; two clearance grooves 6 are provided on both sides of box 1.

[0035] Two fasteners 7 are provided on each side inside the box body 1, with their middle parts hinged to the inner side wall of the box body 1; a baffle 8 is provided below the fasteners 7, and an inclined switch plate 9 is provided at the bottom of the baffle 8; a compression spring 10 is provided between the baffle 8 and the side wall of the box body 1; mounting plates 20 and 21 are welded and fixed to the two ends of the compression spring 10 respectively; mounting plate 20 is fixed to the side wall of the box body 1 by bolts; mounting plate 21 is fixed to the baffle 8 by bolts.

[0036] The movable plate 11 is located on the outer side of both sides of the box body 1, and a slider 12 is set on the upper side of each inner wall. The slider 12 is located in the slide groove 3 and slides with the guide post 4. The bottom of the slider 12 abuts against the top of the compression spring 5, and can drive the movable plate 11 to move upward under the elastic force of the compression spring 5. Two sealing plates 13 are provided below the movable plate 11. The sealing plates 13 are located outside the corresponding clearance grooves 6, which can prevent external debris from passing through the clearance grooves 6 and entering the box body 1. A second switch plate 14 is provided inside the sealing plate 13. The second switch plate 14 passes through the clearance groove 6 and enters the box body 1, and cooperates with the first switch plate 9.

[0037] The lid 15 is located above the box body 1, and two limiting strips 16 are provided on the inner sides of its two side walls to cooperate with the top of the corresponding buckle 7.

[0038] In this embodiment, the height of the two side panels of the box body 1 is lower than the height of its front and rear wall panels; the top of the fastener 7 extends beyond the height of the two side panels of the box body 1 and is the same height as the front and rear wall panels of the box body 1. Correspondingly, the lower ends of the two side walls of the lid 15 are lower than the lower ends of its front and rear wall panels. When the lid 15 is opened, the movable plate 11 moves upward under the action of the compression spring 5 until the top of the movable plate 11 is flush with the top of the fastener 7. At this time, the fastener 7 is blocked by the movable plate 11, which can prevent it from contacting and colliding with external objects.

[0039] When it is necessary to close the lid 15, simply align the two side walls of the lid 15 with the movable plates 11 on both sides of the box body 1, and then press the lid 15 down. Additionally, the movable plates 11 have positioning grooves 22 at their top; the lower sides of the lid 15 have positioning plates 23 corresponding to the positions of the positioning grooves 22. When the positioning plates 23 on both sides of the lid 15 enter the positioning grooves 22 at the top of the movable plates 11, it can be determined that the lid 15 is aligned with the box body 1; at this time, pressing down the lid 15 will smoothly close the lid 15 onto the box body 1, causing the latch 7 to contact and mutually limit the positioning strips 16 on the inner side of the lid 15.

[0040] It should be noted that the second switch plate 14 includes two L-shaped limiting plates 17; the vertical plates of the two limiting plates 17 are connected by a second limiting plate 18, and its horizontal plate passes through the clearance groove 6 and is welded to the inner side of the sealing plate 13; the inclined second switch plate 14 is located between the two limiting plates 17 and below the second limiting plate 18. During the process of closing the cover 15, the movable plate 11 moves downward, at which time the first limiting plate 17 and the second limiting plate 18 move downward along the surface of the baffle 8.

[0041] On the other hand, a handle groove 19 is provided on the outer side of the movable plate 11, which allows the user to insert their fingers to apply force to the movable plate 11. When it is necessary to open the cover 15, the movable plate 11 can be manually pressed down, causing the limiting plate 18 on the second switch plate 14 to move downward and engage with the first switch plate 9. When the limiting plate 18 contacts the first switch plate 9 and applies downward pressure to the first switch plate 9, the baffle 8 below the latch 7 will compress the second spring 10 to retract it; at this time, the top of the latch 7 will move away from the limiting strip 16. After the top of the latch 7 disengages from the limiting strip 16, the cover 15 can be easily removed from the box body 1.

[0042] After the lid 15 is removed, the movable plate 11 moves upward along the guide post 4 under the action of the second compression spring 10; the baffle 8 abuts against the vertical plate of the first limiting plate 17 under the action of the first compression spring 5, and the first limiting plate 17 and the second limiting plate 18 move upward with the movable plate 11; at the same time, the vertical plate of the first limiting plate 17 also limits the baffle 8, so that the top of the fastener 7 remains vertical and does not change. When the slider 12 on the movable plate 11 moves in the slide groove 3 to abut against the top of the slide groove 3, the movable plate 11 stops moving upward; at this time, the top of the movable plate 11 is flush with the top of the front and rear wall panels of the box body 1 and the top of the fastener 7.

[0043] This utility model provides a photovoltaic power generation module junction box that is easy to assemble and disassemble. By pressing down on the movable plate 11 set on the outside of the box body 1, the switch one and the switch plate two 14 cooperate to change the contact position between the buckle 7 and the limiting strip 16 inside the box cover 15. The buckle 7 can be separated from the limiting strip 16 without the need for external tools. The box cover 15 can be easily and quickly removed from the box body 1, and damage to the box body 1 or the box cover 15 can be avoided. It is very practical and has good market application prospects.
