[0026] Specific embodiments, such as Figure 1-3 The diagram shows a semi-potting power supply box that is easy to assemble, comprising: a lower shell 1, which has a shell mounting groove 2 penetrating the lower shell 1, and nut posts 3 at both ends of the lower shell 1 and located in the shell mounting groove 2; end caps 4, which are located at both ends of the shell mounting groove 2, and the end caps 4 have end cap mounting grooves 5 and first positioning holes 6 corresponding to the nut posts 3, and first positioning protrusions 7 on both sides of the end caps 4 and located in the end cap mounting grooves 5; a circuit board 8, which can be respectively embedded in the end cap mounting grooves 5 at both ends, and the circuit board 8 has first positioning grooves 9 on both sides that correspond to and match the first positioning protrusions 7, and the circuit board 8 has second positioning holes 10, when the first positioning protrusions 7 are engaged in the first positioning grooves 9, the second positioning holes 10 correspond to the first positioning holes 6 and the nut posts 3. During assembly, first install the two end caps on both ends of the circuit board, so that the first positioning card protrusion is engaged in the corresponding first positioning card slot. At this time, the second positioning hole corresponds to the first positioning hole. Then, install the end caps and the circuit board together in the housing mounting slot, and let the nut post extend into the first positioning hole to ensure that the second positioning hole and the connection hole of the nut post are aligned. Finally, fix it with screws. The assembly is convenient and has high assembly accuracy.
[0027] Specifically, the semi-potting power supply box also includes a glue baffle 13. There are two first positioning protrusions 7, which are arranged opposite each other to form a glue baffle mounting groove 14. The two glue baffles 13 are respectively disposed on the glue baffle mounting grooves 14 of the two end caps 4, and the two glue baffles 13, the circuit board 8 and the lower shell 1 form a potting cavity.

This facilitates easy assembly and disassembly.
[0032] Furthermore, the side plate portion 12 is provided with a plurality of heat dissipation grooves 21 on the side away from the housing mounting groove 2, which are arranged along the through direction of the housing mounting groove 2. This improves heat dissipation performance.
[0033] Specifically, the potting cavity is provided with a thermally conductive adhesive for conducting the heat dissipated by the circuit board 8. Preferably, thermally conductive silicone grease is used, which has the advantage of excellent thermal conductivity, thus facilitating the transfer of heat dissipated from the circuit board to the side plate portion 12, and then dissipating the heat to the outside through the heat dissipation grooves 21 on the side plate portion 12.
