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 solar cell controller box, includes has lower open-ended last box body 1, goes up the lateral wall of box body 1 and has seted up the mouth 10 that charges and be used for being connected with the lamp wire connector 11, goes up the lower extreme cover of box body 1 and is equipped with the sealing lower cover 2 of lower open-ended, the lower terminal surface shaping of going up box body 1 has downwardly extending's sealing portion 12, and the middle part shaping of sealing portion 12 has the installation cavity 120 that is used for fixed PCB board, the up end shaping of lower cover 2 has the sealing caulking groove 20 that is used for sealing portion 12 male, and is provided with the sealing rubber gasket with sealing portion 12 bottom offset in the sealing caulking groove 20.

In the specific implementation process, the upper box body needs to be aligned to insert the sealing part 12 into the sealing caulking groove 20, and in the insertion process, the sealing caulking ring needs to be forced and extruded to a certain extent, so that the sealing performance is enhanced;

it is worth mentioning that the wires connected with the PCB are often LED wires extending out of the connection ports and are used for being connected with the LED lamps; a lead connected to the charging port 10 for charging the battery; the solar panel is arranged on the upper surface of the upper box body, penetrates into the upper surface of the upper box body at the bottom of the solar panel and is connected with the PCB.

Preferably, the inner side wall of the upper case 1 and the outer side wall of the sealing portion 12 are formed with a plurality of bolt installation cavities 13 with downward openings, the bottom of each bolt installation cavity 13 is formed with a downwardly extending stud 14, threaded holes are formed in the studs 14, and the lower surface of the lower cover 2 is provided with a bolt installation groove 21 corresponding to the stud 14.

In the implementation process, the formed bolt installation cavities 13 are all arranged on the outer side of the sealing part, so that the influence on the sealing part is not easy to cause when the bolts are fastened and matched up and down, and the sealing performance is ensured.
