In order to ensure the safety and stability of photovoltaics during use, a photovoltaic module auxiliary fixing device is needed, which is mainly used in conjunction with photovoltaic brackets to ensure that photovoltaic modules can operate stably under various environmental conditions. Existing photovoltaic module auxiliary fixing devices mainly use fixing clamps to fix photovoltaic wires, reduce damage and movement of wires during installation and use, and use bolts to fix the junction box.

[0003] Existing application number CN201920251041.6 This utility model discloses an auxiliary fixing device for a flexible photovoltaic module junction box, including a main metal plate, a screw, a fixing block and a spring guide assembly. The main metal plate is bent to form a U-shaped mounting groove, one end of the screw is movably connected to the fixing block, the fixing block is located on the inner side of the U-shaped mounting groove, the screw passes through the main metal plate, and one end of the spring guide assembly is fixedly connected to the fixing block. The flexible photovoltaic module junction box is clamped and fixed by rotating the screw to push the fixing block, so that the installation of the auxiliary device can be achieved. When disassembling the device, it is only necessary to rotate the screw in the opposite direction and then remove the junction box. The operation is simple, no tools are required, and it can be operated by hand. The spring guide assembly can ensure the stability of the force at both ends of the fixing block, ensure the stability during fixing, and provide a certain resilience during disassembly, making disassembly easier and more convenient.

[0004] Based on the above, the existing photovoltaic module auxiliary fixing device usually uses a fixing clip to install the line at the connection between the bracket or the components to prevent the line from loosening or sagging, but the fixing clip fixes the wiring harness tightly to the inside of the bracket. When encountering natural weather such as wind and rain, the wiring harness or the bracket is prone to shaking and causing wear on the wiring harness. Severe wear of the wiring harness is prone to safety accidents. Moreover, the fixing clip is mainly made of plastic material, which is prone to aging under long-term wind and sun. It is easy to break when the staff performs maintenance on the photovoltaic, and replacement is cumbersome. In addition, when maintaining the wiring harness junction box, disassembly is cumbersome, affecting the overall maintenance efficiency. Utility Model Content
