The photovoltaic junction box body 1 includes a box body 11, the bottom of which is provided with an annular groove 12, and the two sides of which are symmetrically provided with insertion holes 13. The base plate 2 is provided with a wire through hole 21 in the middle, and the upper end of the base plate 2 is provided with a limiting strip 22 that matches the annular groove 12. The limiting components 3 include a push plate 31, a spring 32, and a fixing rod 33. The fixing rod 33 is fixed to the base plate 2, the push plate 31 is slidably disposed on the fixing rod 33, the spring 32 is sleeved on the guide rod 311 of the push plate 31, and the front end of the push plate 31 is provided with a plug block 312 that is inserted into the insertion hole 13.

The lead wire of the photovoltaic panel passes through the wire hole 21. Then, the push plate 31 is pulled outward to compress the spring 32 and make room. The annular groove 12 at the bottom of the box body 11 of the photovoltaic junction box 1 is aligned with the limiting strip 22 for docking. After the push plate 31 is released, the insertion block 312 at the front end of the push plate 31 is inserted into the insertion hole 13 under the pushing force of the spring 32, thereby fixing the photovoltaic junction box 1. This facilitates the replacement of the photovoltaic junction box 1 in the future. The photovoltaic junction box 1 can be removed by simply operating the limiting component 3. The operation efficiency is high, and the lead wire will not be cut.
