Abstract: 本实用新型属于新能源工程的柔性方案技术领域，具体涉及一种柔性自平衡光伏支架连接件。本实用新型包括柔性拉索、至少两副平衡件、两副光伏板夹持件、两块上钢板、下钢板和拉索嵌入板。本实用新型将上钢板与下钢板通过平衡件连接为一体，保证了上、下钢板分别进行变形，有效地将上钢板连接的光伏组件与下钢板连接的拉索分割开，有效避免了拉索与光伏组件联合变形，确保了光伏组件在平衡件的作用下达到自平衡状态，减少了光伏组件受弯和受扭的隐患。上、下钢板分别与光伏组合件和拉索嵌入装置采用可拆卸连接方式，方便组合件进行安装更换。将拉索与光伏组件连接的一起，避免了风振作用下光伏组件之间的碰撞挤压，大大提高了光伏组件的使用寿命。
