Description

Technical Field

[0001] The utility model relates to the technical field of micro-inverters, and specifically relates to a connection structure for micro-inverter components. Background Technique

[0002] A micro-inverter generally refers to an inverter with a power less than or equal to 1000 watts and component-level MPPT in a photovoltaic power generation system. Its full name is a micro photovoltaic grid-connected inverter. "Micro" is relative to the traditional centralized inverter. Generally, a micro-inverter is only connected to one component and controls the component individually.

[0003] According to the search, the Chinese patent document, publication number: CN214480317U, discloses a connection structure for micro-inverter components. In this solution, one micro-inverter is connected to sixteen component bodies, which reduces the usage cost of the inverter. At the same time, after using one inverter to connect sixteen component bodies, the ratio of the total power of the components to the AC power of the micro-inverter is maximized. However, this connection structure for micro-inverter components still has defects during use. The connection structure of this device provides poor protection for the micro-inverter and is not convenient for assembly. Content of the Utility Model

A fixed groove 4 is opened on the front surface of the fixed frame 1. First card slots 5 are opened on the left and right side walls of the fixed groove 4. A limiting groove 8 is opened on the top wall of the fixed frame 1. A limiting plate 15 is arranged inside the limiting groove 8. A protection component 3 is arranged at the upper end of the fixed frame 1;

[0032] The protection component 3 includes a top cover 18 and a second fixing plate 14. The top cover 18 is fixedly arranged on the upper end surface of the second fixing plate 14. Handles 16 are fixedly arranged on the left and right sides of the second fixing plate 14.

[0033] Specifically, a first fixing plate 9 is fixedly arranged on the rear end face of the fixing frame 1, and a plurality of first mounting holes 10 are formed in the top of the first fixing plate 9. The advantage is that the setting of the first mounting holes 10 facilitates the user to fix the second fixing plate 14, that is, to complete the installation of the top cover 18. At the same time, the setting of the first card slot 5 facilitates the user to install some protection devices, such as toughened glass, grating plates, filter plates, protection plates, etc.

[0034] Specifically, a plurality of circular grooves 7 are formed in the inner bottom wall of the fixing frame 1, and the circular grooves 7 penetrate through the bottom wall of the fixing frame 1. The advantage is that the circular grooves 7 penetrate through the bottom wall of the fixing frame 1, which facilitates the micro-inverter body 11 to communicate with the outside.

[0035] Specifically, a micro-inverter body 11 is arranged inside the fixing frame 1. Mounting plates 12 are fixedly arranged on the left and right end faces of the micro-inverter body 11. Second mounting holes 13 are formed in the front of the mounting plates 12, and an auxiliary component 2 is arranged at the front end of the first fixing plate 9. The advantage is that the setting of the mounting plates 12 plays an auxiliary fixing effect, and the setting of the second mounting holes 13 facilitates the user to install the device outside.

[0036] Embodiment 2:

[0037] As Figures 1-4 shown, as an improvement over the previous embodiment. Specifically, the auxiliary component 2 includes a limiting plate 15 and a mounting plate 12. Second card slots 6 are formed in the left and right side walls of the fixing frame 1. The second card slots 6 are located at the rear end of the limiting slots 8, and the mounting plate 12 is arranged inside the second card slots 6. The advantage is that the setting of the second card slots 6 plays a limiting effect to a certain extent. The user can snap the mounting plate 12 into the second card slots 6, which facilitates the user to install the micro-inverter body 11.

[0038] Specifically, two limiting plates 15 are fixedly arranged on the lower end face of the second fixing plate 14. The advantage is that during installation, the user can snap the limiting plates 15 into the limiting slots 8, avoiding the need for the user to align the third mounting holes 17 and the first mounting holes 10 one by one, thereby reducing the operation.

[0039] Specifically, a plurality of third mounting holes 17 are formed in the top wall of the second fixing plate 14. The third mounting holes 17 are located at the rear end of the top cover 18. The advantage is that the user can use an external mounting device to pass through the third mounting holes 17 and the first mounting holes 10 in sequence, thereby completing the fixation of the second fixing plate 14, and thus completing the installation of the top cover 18. The setting of the top cover 18 plays a certain protection effect.

[0040] In use, the device uses an external power supply and control device. The user inserts the mounting plate 12 into the second card slot 6, which facilitates the installation of the micro-inverter body 11 by the user. Subsequently, due to the setting of the first card slot 5, it is convenient for the user to install some protection devices, such as tempered glass, grid plates, filter plates, protection plates, etc. Then, the user inserts the limit plate 15 into the limit slot 8, avoiding the need for the user to align the third mounting hole 17 and the first mounting hole 10 one by one, and then passing through the external mounting device successively through the third mounting hole 17 and the first mounting hole 10, thereby completing the fixation of the second fixing plate 14 and thus completing the installation of the top cover 18.
