Detailed Description
The utility model is further described in the following embodiments with reference to the figures, see fig. 1-3:
the utility model provides a controller box for solar cell, includes that the top has open-ended lower box body 1, and lower box body 1 upper cover is equipped with the sealing open-ended upper cover 2 is provided with sealed packing ring 3 between upper cover 2 and the lower box body 1, and the lower terminal surface shaping of upper cover 2 has first sealed fender along 20, has seted up the sealed caulking groove 200 of undercut on the first sealed fender along 20, the up end shaping of sealed packing ring 3 has the butt portion 30 that is used for embedding sealed caulking groove 200, the outer edge shaping of lower box body 1 have with the sealed fender along 10 of second that the terminal surface supported under the sealed packing ring 3, the outer edge of second sealed fender along 10 upwards extends and the shaping has the parcel the sealed limit 100 of first sealed fender along 20 lateral walls.
Preferably, the cross section of the sealing rubber ring 3 is of an inverted T-shaped structure.
In the implementation process, the sealing rubber ring is matched with the lower end of the upper cover in advance. In the matching process, the abutting part is embedded into the sealing caulking groove 200, so that the sealing rubber ring 3 of the sealing caulking groove can be fixed at the position of the first sealing baffle edge 20 at the lower end of the upper cover in advance. Then the upper cover and the lower box body 1 are buckled, and a common buckling mode is that bolts are tightly matched. The lower end face of the sealing rubber ring abuts against the upper end face of the second sealing baffle edge during the assembly, so that the sealing of the joint of the lower end face of the sealing rubber ring and the second sealing baffle edge is achieved, and meanwhile the sealing rubber ring is not easy to twist during the sealing, and good sealing performance is guaranteed.
