This invention secures the waterproof cap 1 to the photovoltaic modules at the ridge using bolts 2 and the winged nut 3, facilitating waterproofing at the photovoltaic module connection points. This invention improves the waterproofing effect by optimizing the structure of the waterproof cap. The plastic wing nut 3 includes a metal locking component with a threaded hole, which is threadedly connected to the bolt.
