[0002] In the field of photovoltaic power generation, the high-efficiency photovoltaic box is an important component connecting photovoltaic modules and electrical systems. Its performance and reliability have a significant impact on the stability and efficiency of the entire power generation system. Existing high-efficiency photovoltaic boxes have a compact internal structure and usually use multiple screws to fix the cover to the main body of the photovoltaic box. Although this method of fixing the cover ensures the connection to a certain extent, it has many inconveniences in actual operation. When it is necessary to frequently perform wiring or maintenance of the internal terminals of the photovoltaic box, the disassembly and tightening of multiple screws is time-consuming, affecting the maintenance of the photovoltaic box and the terminal wiring operation. Therefore, in order to address the shortcomings of the above-mentioned cover fixing method, this utility model proposes a compact high-efficiency photovoltaic box. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-5 The diagram shows a compact, high-efficiency photovoltaic box, including a photovoltaic box body 1, and also a sealing component and a locking component;

[0024] Specifically, the sealing component is used to seal the top of the photovoltaic box body 1. The sealing component includes a box cover 2 that is inserted and connected to the top of the photovoltaic box body 1. A positioning part for initial fixing of the box cover 2 is provided on one side of the inner wall of the photovoltaic box body 1.

[0025] It should be noted that a wiring protection groove 5 is provided on one side of the photovoltaic box body 1. The wiring protection groove 5 is used for the entry of cables. The working principle of the photovoltaic box body 1 and the wiring protection groove 5 is the same as that of the PV-CY22xyz photovoltaic box.

[0026] Specifically, the positioning part includes a positioning insert 101 disposed on one side of the inner wall of the photovoltaic box body 1, and a positioning groove 201 for the positioning insert 101 to be inserted and positioned is provided on the side of the box cover 2;

[0027] It should be noted that the positioning insert 101 is fixed to the inner wall of the photovoltaic box body 1 by integral injection molding. The cross-sectional dimension of the positioning groove 201 is larger than that of the positioning insert 101, which facilitates positioning and insertion.

[0028] Specifically, the locking component is located on the other side of the inner wall of the photovoltaic box body 1. The locking component is used to fix the photovoltaic box body 1 and the box cover 2. The locking component includes an elastic insert 3 located on the side of the box cover 2. The elastic insert 3 has a snap-fit ​​part on the side near the inner wall of the photovoltaic box body 1. The inner wall of the photovoltaic box body 1 has a compression protrusion 102 for fixing the snap-fit ​​part.

[0029] It should be noted that the snap-fit ​​part includes a locking protrusion 301, which is located on the side of the elastic insert 3. The locking protrusion 301 is inclined and is used to contact and snap with the side of the extrusion protrusion 102. Both the elastic insert 3 and the locking protrusion 301 are made of brass and are fixed by integral die casting. The insertion point of the elastic insert 3 and the cover 2 is fixed by adhesive.

[0030] A pressing part 4 for squeezing and unlocking the card is inserted and connected to the outer side of the photovoltaic box body 1;

[0031] Specifically, the pressing part 4 includes a rod 401 that is inserted and connected to the top side of the photovoltaic box body 1. The end of the rod 401 is provided with an oblique pressing port 4011, which is used to lock the oblique pressing release of the protrusion 301. A spring-loaded part for release and reset is provided on the outside of the rod 401 and at the insertion point between the rod 401 and the photovoltaic box body 1.

[0032] It should be noted that the spring-loaded component 4 includes an elastic ring 402, which is sleeved on the outside of the insertion rod 401. The middle part of the elastic ring 402 is glued to the outside of the insertion rod 401, and the outside of the elastic ring 402 is glued to the inner wall of the insertion hole on the outside of the photovoltaic box body 1 for the insertion rod 401 to move through.

[0033] Specifically, the side of the lid 2 is provided with an ejector groove 202. The ejector groove 202 is used to provide space for the elastic insert 3 to move under the pressure of the pressing part, so as to prevent the locking protrusion 301 from being unable to disengage from the pressing protrusion 102.

[0034] A damping block 6 is bonded to the bottom of the photovoltaic box body 1. The damping block 6 is used to increase the friction between the photovoltaic box body 1 and the installation contact surface.

[0035] In actual use, by setting a positioning part and a locking component at the connection between the cover 2 and the photovoltaic box body 1, the staff can press the snap-fit ​​part on the side of the elastic insert 3 by pressing the pressing part 4 to unlock and disengage the snap-fit ​​part from the pressing protrusion 102, thereby unlocking and disengaging the cover 2. Compared with using multiple screws to fix the cover 2 and the photovoltaic box body 1, this method makes it easier for the installer to quickly disengage the cover 2 and perform terminal wiring operations, avoiding the time-consuming operation of disassembling and tightening the screws of the cover 2.
