Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic inverters, and more specifically to a photovoltaic inverter wiring docking mechanism that prevents loosening and falling off. Background Art

[0002] A photovoltaic inverter converts the variable DC voltage generated by photovoltaic solar panels into AC power at a mains frequency, which can be fed back into the commercial power transmission system or used by off-grid power grids. After the photovoltaic inverter is connected to the conductive wires, any pull on the wires can affect the connection, causing them to loosen or become damaged.

[0003] After searching, the utility model patent with publication number CN221428125U discloses a photovoltaic inverter wiring docking mechanism that prevents loosening and falling off, which solves the problem in the prior art that personnel need to connect the photovoltaic inverter and the wires. If the wires connected to the photovoltaic inverter are not effectively protected, once the wires are pulled, the entire wires may fall off, resulting in the photovoltaic inverter being unable to be used normally; the photovoltaic inverter wiring docking mechanism that prevents loosening and falling off includes a photovoltaic inverter body, and one side of the photovoltaic inverter body is detachably connected to an outer frame; the patent ensures that even if one end of the wire is pulled, the other end of the wire will not loosen or fall off due to the clamping force, thereby ensuring the normal and stable operation of the photovoltaic inverter body and improving the practicality of the photovoltaic inverter body.

[0004] However, the aforementioned patent has the following drawbacks: The clamping force between the rubber sheet and the rubber block is not effective in preventing the wiring from being pulled; when the pulling force is high, the pulling force still acts on the wiring. Furthermore, after the outer frame is installed on the photovoltaic inverter, wiring operations are not convenient. Therefore, we propose a photovoltaic inverter wiring docking mechanism that prevents loosening and falling off. Utility Model Content

[0014] (1) In the present invention, a U-shaped anti-drop cover is installed below the photovoltaic inverter body, so that the wire extends from the wire inlet groove into the inner cavity of the winding box, and the wire is wound on two winding poles.
