Technical Field

[0001] The utility model relates to the technical field of photovoltaic connectors, in particular to an anti-dropping photovoltaic connector. Background Art

[0002] Photovoltaic connectors are electrical connectors used to connect solar panels and battery panels in solar photovoltaic power generation systems, as well as to connect battery panels with inverters or other electrical equipment. These connectors need to have characteristics such as high temperature resistance, UV resistance, waterproofness and dustproofness to adapt to long-term use in outdoor environments. When selecting photovoltaic connectors, their safety, reliability and compatibility with other components of the system must be considered.

[0003] Photovoltaic connectors can effectively convert solar energy into electrical energy, achieve high-efficiency conversion, and improve the overall performance of the photovoltaic system. High-quality photovoltaic connector design can ensure the stable operation of the system under various environmental conditions, with high reliability and the ability to maintain good working conditions for a long time. However, photovoltaic connectors age over time, and components such as sealing rings and contact pieces may wear out due to long-term use, resulting in reduced connector performance and easy loosening and detachment, reducing operational stability. Utility Model Content

[0004] In view of this, the purpose of the utility model is to propose an anti-detachment photovoltaic connector to solve the problem that the photovoltaic connector ages with the passage of time, and the sealing ring, contact piece and other components may be worn due to long-term use, resulting in reduced connector performance, easy loosening and detachment, and reduced operational stability.

[0005] Based on the above purpose, the utility model provides an anti-loosening photovoltaic connector, including a photovoltaic component and a protective component arranged on the periphery of the photovoltaic component, characterized in that the photovoltaic component includes a connector and a fixer plugged with the connector, and the two ends of the connector are symmetrically provided with an internal fixing component to prevent loosening and a fixing component symmetrically arranged on the outside of the connector;

[0006] The fixing assembly includes a fixing plate symmetrically slidably connected to both ends of the connector and a fixing slot symmetrically opened at both ends of the fixer, and the fixing slot is also symmetrically opened at both ends of the connector. A fixing slot for fixing is symmetrically opened at one end of the fixing slot at one end of the fixer, and the fixing slot is also symmetrically opened at one end of the fixing plate, and a fastening rod for fixing is inserted at one end of the fixing slot.

[0007] Optionally, sliding grooves slidably connected to the fixed plate are symmetrically provided inside the fixed hollow groove, and sliding rods slidably connected to the sliding grooves are symmetrically fixed at both ends of the fixed plate.

[0008] Optionally, the internal fixing component includes an elastic fixing rod symmetrically fixedly installed at both ends of the connector and a clamping groove symmetrically opened on the fixer and the elastic fixing rod for clamping. One end of the elastic fixing rod is fixed with a clamping block clamped with the clamping groove, and one end of the clamping groove is symmetrically opened with a clamping groove clamped with the clamping groove.

[0009] Optionally, an electrical connection hole is opened at one end of the connector, and an electrical connection rod electrically connected to the electrical connection hole is fixedly connected to one end of the fixture, a power cord is fixedly connected to one end of the fixture, and the power cord is also arranged at one end of the connector.

[0010] Optionally, the protective assembly includes a protective shell one and a protective shell two which is plugged and fixed to the protective shell one, the outer periphery of the protective shell two is evenly provided with receiving grooves for reducing external collision force and accommodating buffer plates, and the inside of the receiving grooves are symmetrically and evenly fixed with return springs for increasing buffer force, and the buffer plates are also evenly arranged on the outer periphery of the protective shell one.

[0011] Optionally, a plug-in fixing block which is plugged and fixed with the protective shell one is fixed at one end of the protective shell two, and the plug-in fixing block is symmetrically fixed at one end of the protective shell two.

Then, the fixing plate is slid from the inner side of the fixed empty slot of the connector to the inner side of the fixed empty slot on both sides of the fixer through the sliding slot and the sliding rod. When the fixing slot at one end of the fixing plate overlaps with the fixing slot at one end of the fixed empty slot of the fixer, the fastening rod is plugged into the inner side of the fixing slot to complete the fixation of the connector and the fixer. The internal and external double fixation is performed by the internal fixing component and the fixing component to increase the plug-in stability and firmness of the connector and the fixer.
