Description

Technical Field

[0001] This utility model relates to the field of photovoltaic junction box technology, specifically a photovoltaic junction box that is easy to disassemble. Background Technology

[0002] With the continuous development of renewable energy technologies, the photovoltaic industry has been widely applied globally. As an indispensable part of a photovoltaic system, the photovoltaic junction box's main function is to connect the cables of the photovoltaic modules and protect the internal electrical connections from external environmental influences. In existing photovoltaic junction box designs, the connection between the box body and the cover plate mostly relies on a snap-fit ​​structure. Specifically, the box body has snap-fit ​​clips, while the cover plate has matching snap-fit ​​blocks. Through the cooperation of the snap-fit ​​clips and snap-fit ​​blocks, the cover plate can be firmly fixed to the box body, thereby ensuring the junction box's sealing and electrical safety. When workers need to maintain or replace parts inside the box, tools are usually used to pry open the snap-fit ​​clips for easy disassembly, allowing the cover plate to be removed from the box body.

[0003] However, since the clips are often made of materials such as plastic, their strength is limited. If the operation is not proper during the prying process, the clips can easily be damaged. Since the clips on traditional junction boxes are molded as one piece with the junction box itself, once the clips are damaged, it is often necessary to disassemble the entire junction box and replace it with a new one, which increases maintenance costs. Therefore, in view of the above situation, a photovoltaic junction box that is easy to disassemble is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a photovoltaic junction box that is easy to disassemble. By designing an installation block on the junction box body and setting a plug block that cooperates with the installation block on the buckle, and designing the buckle as a detachable structure, it is possible to avoid disassembling and replacing the entire junction box body when the buckle is accidentally damaged. This solves the problem that once the buckle is damaged, it is often necessary to disassemble and replace the entire junction box, which increases maintenance costs.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a photovoltaic junction box that is easy to disassemble, including a junction box body, mounting blocks and buckles. There are two mounting blocks, which are fixed to both ends of the outer wall of the junction box body. Slots are opened at both ends of the top of the mounting blocks. A groove is opened on one side of the inner wall of the slot. A through hole communicating with the groove is opened on the outer wall of the mounting blocks. Insert blocks are fixed at both ends of the bottom of the buckles. An elastic plate is provided on the insert block. The elastic plate has a protrusion. When the insert block is inserted into the slot, the protrusion protrudes through the through hole.

[0007] Furthermore, the top of the junction box body has an assembly cavity, and the junction box body has a wire-passing hole that communicates with the assembly cavity.

[0008] Furthermore, a cover plate is provided on the top of the junction box body, and a snap-fit ​​plate is fixedly connected to both ends of the cover plate. When the cover plate is fitted with the junction box body, the snap-fit ​​plate engages with the snap-fit.

[0009] Furthermore, when the insert and slot are engaged, the elastic plate engages with the groove, and the elastic plate is made of elastic plastic material.

[0010] Furthermore, when the insert is separated from the slot, there is a gap between the elastic plate and one side of the insert.

[0011] This utility model has the following beneficial effects:

[0012] This utility model designs an installation block on the junction box body, and sets an insertion block on the buckle that cooperates with the installation block. The buckle is designed as a detachable structure, so that if the buckle is accidentally damaged, it is not necessary to disassemble and replace the entire junction box body, avoiding the scrapping of the entire junction box body due to buckle damage, reducing the maintenance cost of photovoltaic system. At the same time, since the buckle can be replaced individually, it also extends the service life of the junction box body.

[0013] This utility model, through its structural design of grooves, perforations, inserts, and elastic plates, allows for easy disassembly and installation of the buckle by personnel through a simple pressing operation. Workers can replace the buckle without the need for complicated tools, thus greatly improving work efficiency.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a photovoltaic junction box that is easy to disassemble, including a junction box body 1, a mounting block 2 and a buckle 3. The top of the junction box body 1 is provided with an assembly cavity, and the junction box body 1 has a wire hole 101, which communicates with the assembly cavity.

[0022] The wire passes through the wire hole 101 into the assembly cavity and then connects to the terminal block located in the assembly cavity.

[0023] The top of the junction box body 1 is provided with a cover plate 4, and the two ends of the cover plate 4 are respectively fixedly connected with snap-fit ​​plates 401. When the cover plate 4 is engaged with the junction box body 1, the snap-fit ​​plates 401 are engaged with the snap-fit ​​plates 3.

[0024] There are two mounting blocks 2, which are fixed to the two ends of the outer wall of the junction box 1 respectively. The top of the mounting block 2 has slots 201 at both ends, and a groove 202 is provided on one side of the inner wall of the slot 201. The outer wall of the mounting block 2 has a through hole 203 that communicates with the groove 202.

[0025] Both ends of the bottom of the buckle 3 are fixed with insert blocks 301. An elastic plate 302 is provided on the insert block 301. The elastic plate 302 has a protrusion 303. When the insert block 301 is inserted into the slot 201, the protrusion 303 passes through the through hole 203. The protrusion 303 and the elastic plate 302 are integrally formed.

[0026] When the insert 301 engages with the slot 201, the elastic plate 302 engages with the groove 202. The elastic plate 302 is made of elastic plastic material.

[0027] When the insert 301 is separated from the slot 201, there is a gap between the elastic plate 302 and one side of the insert 301.

[0028] In this embodiment, when the operator uses a tool to pry up the latch plate 401 on the latch 3 to remove the cover plate 4, if the latch 3 is damaged due to improper operation, the operator can press the protruding elastic plate 302 on both sides of the latch 3 to retract it into the groove 202 when replacing the latch 3. At the same time, the operator can move the latch 3 upward to remove the insert block 301 from the slot 201, thus removing the latch 3.
