Problems solved by technology
This design can ensure the use of the connector when the electrical performance requirements of the connector are not particularly high. However, with the wide use of high-power photovoltaic arrays and photovoltaic systems, the electrical performance requirements of the connector are getting higher and higher. , product standards are becoming more and more stringent, the design of this metal collar does not improve the electrical performance of the connector, especially the creepage distance is too far to meet the standard requirements; and the ability to prevent the connector from loosening is not very good excellent

The invention proposes a photovoltaic system connector with high reliability and excellent electrical performance, which includes a male plug and a female plug. Both the male plug and the female plug include a shell, a nut connected to the shell, and a Cable locks and washers, insulating sleeves and metal terminals located in the housing; female sockets and male pins include cable riveting parts, female sockets and male pins adjacent to the circumference of the cable riveting part There is a protruding structure in one direction, and the other end is a tapered structure including at least two flaps, and a plurality of protrusions with a certain length and width extend from the socket body to the opening end of the tapered structure. The photovoltaic system connector of the present invention can not only ensure the structural strength of the connector, but also significantly increase the creepage distance of the connector, improve its electrical performance, ensure the accuracy of component assembly and the reliability of connection, and avoid the possibility of cables and There is a loose connector problem.
Description
technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a photovoltaic system connector with high reliability and excellent electrical performance. Background technique [0002] With the global climate change and the increasingly severe environmental pollution caused by traditional fossil energy, the green and renewable energy industry has developed rapidly in the past ten years. Solar energy is a renewable resource, and the solar cell technology that uses the photovoltaic effect to generate electricity has attracted worldwide attention. Solar cells are made of materials that can produce photovoltaic effects, such as silicon, gallium arsenide, indium selenide copper and other materials, which can convert light energy into electrical energy. At present, photovoltaic modules composed of multiple solar cells are widely used to build various photovoltaic power generation systems, or used as building curtain walls to build e...
