Description

Technical Field

[0001] This utility model relates to the field of photovoltaic junction box technology, specifically a photovoltaic junction box with optimized heat dissipation. Background Technology

[0002] As a key component of solar photovoltaic power generation systems, photovoltaic junction boxes are mainly used to connect and protect the electrical energy generated by photovoltaic modules. Their technological development has continued to evolve along with the needs of the photovoltaic industry. Early junction boxes adopted a simple diode bypass protection structure to reduce the damage caused by hot spot effects. The third-generation technology further introduced wide bandgap semiconductor devices such as gallium nitride to reduce conduction losses and integrated wireless transmission technology to achieve remote fault diagnosis, so as to meet the industry's needs for high reliability, long life and intelligent operation and maintenance.

[0003] However, current photovoltaic junction boxes often use screws for installation and positioning, but after prolonged use, the screws may strip, making it impossible to open the photovoltaic junction box for maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a photovoltaic junction box with optimized heat dissipation to address the shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: including a box assembly, wherein a snap-fit ​​component is provided on the box assembly, the snap-fit ​​component can limit the position of the box assembly, and a heat dissipation structure is provided on the box assembly, wherein the heat dissipation structure can dissipate heat from the interior of the box assembly.

[0006] Furthermore, the box assembly includes a first box, on which a limiting groove is formed, and a limiting member is slidably connected within the limiting groove, the limiting member being fixedly disposed on a second box.

[0007] Furthermore, the first box body has several wiring ports on each side, and the second box body has two locking rods on each side, with a locking groove on each of the four locking rods.

[0008] Furthermore, the heat dissipation structure includes a plurality of heat dissipation slots formed on the first box and the second box, and a dustproof net is provided in each of the first box and the second box, with the two dustproof nets corresponding to the positions of the plurality of heat dissipation slots respectively.

[0009] Furthermore, the snap-fit ​​assembly includes two fixing members fixedly mounted on the first housing. Each of the two fixing members is provided with two spring telescopic members. The output end of each pair of spring telescopic members is fixedly connected to a connecting rod. The two connecting rods are respectively connected to two sliding rods one-to-one. Each end of the two sliding rods is provided with a snap-fit ​​member. The four snap-fit ​​members are respectively corresponding to the positions of the four snap-fit ​​rods. The four snap-fit ​​members can respectively enter the four snap-fit ​​slots one-to-one.

[0010] Furthermore, the snap-fit ​​assembly also includes protective covers, each of the two protective covers having two sliding members, the first housing having four sliding grooves, the four sliding members being slidably connected to the four sliding grooves respectively, each of the two protective covers having two mounting grooves, the first housing having four fixing blocks, the four fixing blocks being located in the four mounting grooves respectively, the four fixing blocks being connected to one end of four spring members respectively, the other end of the four spring members being connected to the two protective covers respectively, and the four spring members being located in the four mounting grooves respectively.

[0011] Compared with the prior art, the photovoltaic junction box with optimized heat dissipation provided by this utility model allows for maintenance when problems occur inside the junction box. By sliding the two protective covers, the connecting rods can be moved, and then the two connecting rods can be pushed to release the four locking components, allowing the second box body to be removed for maintenance. When the first and second boxes need to be locked again, the protective covers and connecting rods can be slid again to move the locking components. The locking components are then inserted into the locking slots, causing the four locking rods to reach their predetermined positions. Releasing the locking rods releases the four spring extension components, causing the four locking components to reset and locking the locking rods. This also locks the first and second boxes. Finally, releasing the two protective covers resets them, providing protection for the locking components again. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1-6This utility model provides a heat dissipation optimized photovoltaic junction box, including a box assembly 1, a snap-fit ​​assembly 2 on the box assembly 1, the snap-fit ​​assembly 2 can limit the position of the box assembly 1, and a heat dissipation structure 11 on the box assembly 1 can dissipate heat inside the box assembly 1. During use, when a problem occurs inside the junction box requiring repair, the two protective covers 26 can be slid, causing the four sliding parts 27 to slide, causing the four spring parts 29 to be compressed and contracted, so that the connecting rod 23 is no longer protected by the protective covers 26, allowing the connecting rod 23 to move. Then, by pushing the two connecting rods 23, several spring telescopic parts 22 can be contracted, causing the two sliding rods 24 to slide, driving the four snap-fit ​​parts 25 to slide, so that the four snap-fit ​​parts 25 can respectively disengage from the four snap-fit ​​slots 18. This allows the four locking components 25 to no longer be restricted, enabling the second box 13 to be removed and the limiting component 15 to leave the limiting groove 14, allowing for maintenance of the junction box interior. When it is necessary to restrict the first box 12 and the second box 13 again, the protective cover 26 and connecting rod 23 can be slid again to move the locking components 25. Then, the limiting component 15 is inserted into the limiting groove 14, causing the four locking rods 17 to reach the predetermined position. At this time, the locking rods 17 are released, causing the four spring telescopic components 22 to release and drive the four locking components 25 to reset, so that the four locking components 25 enter the four locking grooves 18 one by one, thus restricting the locking rods 17. At this time, the first box 12 and the second box 13 are restricted. Then, the two protective covers 26 are released, allowing the two protective covers 26 to reset and protect the locking components 25 again.

[0022] Preferably, the box assembly 1 includes a first box 12, a limiting groove 14 is formed on the first box 12, a limiting member 15 is slidably connected in the limiting groove 14, and the limiting member 15 is fixedly disposed on a second box 13.

[0023] Preferably, the first box 12 has several wiring ports 16 on each side, and the second box 13 has two locking rods 17 on each side, with a locking groove 18 on each of the four locking rods 17.

[0024] Preferably, the heat dissipation structure 11 includes a plurality of heat dissipation slots 1011 formed on the first box 12 and the second box 13. Each of the first box 12 and the second box 13 is provided with a dustproof net 1012. The two dustproof nets 1012 correspond to the positions of the plurality of heat dissipation slots 1011 respectively. The heat dissipation slots 1011 increase the heat dissipation effect on the inside of the junction box, and the dustproof nets 1012 effectively prevent dust from entering the junction box.

[0025] Preferably, the snap-fit ​​assembly 2 includes two fixing members 21 fixedly mounted on the first housing 12. Each of the two fixing members 21 is provided with two spring telescopic members 22. The output end of each pair of spring telescopic members 22 is fixedly connected to a connecting rod 23. The two connecting rods 23 are respectively connected to two sliding rods 24. Each end of the two sliding rods 24 is provided with a snap-fit ​​member 25. The four snap-fit ​​members 25 are respectively corresponding to the positions of the four snap-fit ​​rods 17. The four snap-fit ​​members 25 can respectively enter the four snap-fit ​​slots 18.

[0026] Preferably, the snap-fit ​​assembly 2 further includes a protective cover 26, each of the two protective covers 26 is provided with two sliding members 27, the first housing 12 is provided with four sliding grooves 19, the four sliding members 27 are slidably connected to the four sliding grooves 19 respectively, each of the two protective covers 26 is provided with two mounting grooves 28, the first housing 12 is provided with four fixing blocks 110, the four fixing blocks 110 are respectively located in the four mounting grooves 28, the four fixing blocks 110 are respectively connected to one end of four spring members 29, the other end of the four spring members 29 are respectively connected to the two protective covers 26, and the four spring members 29 are respectively located in the four mounting grooves 28.

[0027] The working principle of this utility model is as follows: When a problem occurs inside the junction box and repair is needed, the two protective covers 26 can be slid to allow the four sliding parts 27 to slide, causing the four spring parts 29 to be compressed and contracted. This removes the protective cover 26 from the connecting rod 23, allowing it to move. Then, by pushing the two connecting rods 23, several spring telescopic parts 22 can be contracted, causing the two sliding rods 24 to slide. This, in turn, causes the four locking parts 25 to slide, allowing them to disengage from their respective locking slots 18. This removes the locking parts 25 from their positions, allowing the second box body 13 to be removed and the limiting parts 15 to disengage from their limiting slots 14. At this point, the inside of the junction box can be repaired. When it is necessary to limit the first box 12 and the second box 13 again, the protective cover 26 and the connecting rod 23 can be slid again to move the snap-fit ​​25. Then, the limiting member 15 is inserted into the limiting groove 14, so that the four snap-fit ​​rods 17 reach the predetermined position. At this time, the snap-fit ​​rods 17 are released to release the four spring telescopic members 22, which drives the four snap-fit ​​members 25 to reset, so that the four snap-fit ​​members 25 enter the four snap-fit ​​grooves 18 one by one, so that the snap-fit ​​rods 17 are limited. At this time, the first box 12 and the second box 13 are limited. Then, the two protective covers 26 are released to reset the two protective covers 26, so that the two protective covers 26 protect the snap-fit ​​members 25 again.
