[0038] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0039] Embodiment 1

[0040] Refer to Figures 1-5, a photovoltaic module junction box, comprising a main body assembly 1, and the main body assembly 1 includes: a box body 11, with a cover body 12 movably connected to its top; a disassembly and assembly component 2 is provided on the box body 11 and the cover body 12, and the disassembly and assembly component 2 includes: cavities 21 symmetrically opened at the top of the box body 11; push rods 22 symmetrically penetrating and connected to the cavities 21; a push plate 221 fixedly connected to one end of the push rod 22 located outside the box body 11; a limiting rod 23 fixedly connected to one end of the push rod 22 located inside the cavity 21; a first spring 24 symmetrically arranged between the inner side wall of the cavity 21 and the limiting rod 23, and the first spring 24 is sleeved outside the push rod 22; limiting blocks 25 symmetrically arranged on the bottom surface of the cover body 12; a fixing mechanism 26 provided on the box body 11 and the cover body 12. The fixing mechanism 26 includes: square grooves 261 symmetrically arranged on the side surface of the box body 11; through grooves 262 symmetrically opened on the box body 11 and the square grooves 261; inserting plates 263 symmetrically arranged on the bottom surface of the cover body 12; second springs 264 symmetrically arranged in the grooves of the inserting plates 263; and pressing plates 265 fixedly connected to the bottoms of the second springs 264. Both the through grooves 262 and the pressing plates 265 have arc-shaped surfaces.

[0041] Before use, the cover body 12 together with the inserting plates 263 at the bottom is far from the box body 11. The staff places the connector inside the box body 11, the cable is placed through the through grooves 262, aligns the inserting plates 263 at the bottom of the cover body 12 with the square grooves 261 on both sides, and covers the cover body 12 downward. The pressing plates 265 fix the cable: the inserting plates 263 enter the inside of the square grooves 261, and the pressing plates 265 contact the upper surface of the cable. When the diameter of the cable is relatively large, during the process of the inserting plates 263 continuously moving downward, the pressing plates 265 are abutted against the top of the cable, and the corresponding second springs 264 are compressed, realizing the fixation of the pressing plates 265 on cables with different diameters. When the cover body 12 moves downward, when the arc-shaped surface at the bottom of the limiting block 25 contacts the limiting rod 23 inside the cavity 21, the limiting rod 23 is pushed by the downward-moving limiting block 25 to move towards the middle of the box body 11, and the first spring 24 is stretched. When the cover body 12 completely covers the box body 11, the limiting rod 23 and the grooves on the limiting block 25 are on the same horizontal line, and the first spring 24 pulls the limiting rod 23 into the grooves of the limiting block 25 to limit the limiting block 25, so that covering the cover body 12 can realize the fixation of the cover body 12, increasing the operation convenience. When it is necessary to remove the cover body 12 for overhauling the connector inside the box body 11, the staff presses the push plates 221 inward simultaneously. The push plates 221 drive the push rods 22 to push the limiting rods 23 out of the grooves on the limiting blocks 25. At this time, the cover body 12 can be removed, facilitating the staff's overhaul. The arc-shaped surfaces on the through grooves 262 and the pressing plates 265 increase the contact area with the cable, thereby increasing the stability after the cable is fixed.

[0042] Embodiment 2

[0043] On the basis of Embodiment 1, an auxiliary function is added.

[0044] Refer to Figures 1-5 , the fixing mechanism 26 further includes a rubber pad 266 fixedly connected to the bottom of the pressing plate 265. A sliding rod 267 is fixedly connected to the top of the pressing plate 265. The second spring 264 is sleeved outside the sliding rod 267. A groove for the sliding rod 267 to move is formed inside the plug board 263. Symmetrically arranged convex blocks 27 are provided on the bottom surface of the cover body 12. A third spring 271 is fixedly connected to a groove symmetrically formed on the top surface of the box body 11. The top of the third spring 271 is fixedly connected to a top plate 272.

[0045] The rubber pad 266 increases the friction when the pressing plate 265 contacts the cable, enhancing the firmness of the fixing of the pressing plate 265. When the pressing plate 265 moves upward according to the diameter of the cable, the sliding rod 267 at the top retracts into the plug board 263 along with the pressing plate 265. The sliding rod 267 is used to maintain the vertical state when the second spring 264 expands and contracts, preventing the second spring 264 from driving the pressing plate 265 to skew when expanding and contracting, which affects the normal insertion of the plug board 263 into the square groove 261. When the cover body 12 is closed, the convex blocks 27 at the bottom of the cover body 12 push the top plate 272 downward and compress the third spring 271. The convex blocks 27 enter the grooves on the box body 11. When the staff simultaneously presses the push plates 221 on both sides, the cover body 12 is jacked up by the deformed third spring 271 after being released from the restriction, facilitating the staff to remove the cover body 12 from the box body 11, increasing the convenience of the staff's operation.

[0046] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
