Abstract
Description
[Technical Field]
[0001] This utility model belongs to the field of power supply box technology, and in particular relates to a sealed, easy-to-install power supply box. [Background Technology]
[0002] A power supply box is a casing used to house the various components of a power supply. The installation of a typical power supply box usually involves the following steps: first, installing the various power supply components inside the main frame of the power supply box; then, fixing the top cover with screws; next, fixing the two end covers of the power supply box with screws; and finally, performing performance testing on the semi-finished product. The aforementioned typical power supply box uses multiple screws to fix the top and end covers. When installing the end covers, the screw holes on the end covers need to be aligned with the screw holes on the main frame before screwing them in, which is inconvenient. Furthermore, if a problem is found during testing, the screws on the end covers and top cover need to be unscrewed to open the end covers and top cover sequentially to inspect the various power supply components inside the power supply box, making disassembly and repair inconvenient.

[0030] Specific embodiments, such as Figure 1-5 A sealed, convenient-installation power supply box is shown, comprising: a main frame 1, which has a U-shaped hollow structure; a top cover 2, which is detachably installed on the top of the main frame 1; end covers 3, which are located at both ends of the main frame 1, the end covers 3 including end cover panels 31 and end cover frame edges 32 extending away from the main frame 1 along the edge of the end cover panels 31; and a positioning and installation mechanism 4, which includes a positioning and installation post 41 located in the main frame 1, a positioning and installation protrusion 42 extending from the lower end of the end cover panels 31 toward the positioning and installation post 41, and a positioning and installation hole 43 passing through the positioning and installation protrusion 42 and matching the positioning and installation post 41. When the positioning and installation hole 43 is fitted onto the positioning and installation post 41, the end cover 3 is embedded in the main frame 1 and the outer wall of the end cover frame edge 32 abuts against the inner wall of the main frame 1. During assembly, first, the positioning mounting protrusion on the end cap extends into the main frame body, and the positioning mounting hole is fitted onto the positioning mounting post. At this point, the end cap is embedded in the main frame body, and the outer wall of the end cap frame abuts against the inner wall of the main frame body to restrict the rotation of the end cap. Finally, the top cover is detachably installed on top of the main frame body without the need for screw fixation, making disassembly, assembly, and maintenance convenient. In addition, the end cap 3 is embedded in the main frame body 1, and the outer wall of the end cap frame 32 abuts against the inner wall of the main frame body 1, which can improve the support strength and prevent the deformation of the U-shaped hollow structure of the main frame body 1.
[0031] Specifically, the end cap frame 32 includes an upper frame 321, a lower frame 322, and two oppositely arranged side frames 323. One end of the side frame 323 away from the end cap panel 31 is provided with a baffle portion 5. When the positioning mounting hole 43 is fitted onto the positioning mounting post 41, the ends of the main frame 1 and the top cover 2 abut against the baffle portion 5, thus improving sealing.
[0032] In addition, the main frame 1 includes a base plate 11 and two oppositely arranged side plates 12. The end of the base plate 11 is provided with a plurality of U-shaped connecting grooves 61 arranged along the width direction, and the lower frame 322 is provided with a plurality of first clearance grooves 62 corresponding to the U-shaped connecting grooves 61. The power box of this application is installed and fixed on the product by the U-shaped connecting grooves 61 and screws, and the first clearance grooves 62 are provided to facilitate installation.
[0033] Furthermore, the upper frame 321 is provided with a second relief groove 63 corresponding to the first relief groove 62, and the end of the top cover 2 is provided with a third relief groove 64 corresponding to the second relief groove 63. The second relief groove 63 and the third relief groove 64 provide relief, making disassembly and assembly more convenient.
[0034] More specifically, the upper frame 321 has a plurality of cable routing grooves 7 recessed at its upper end, arranged along the width direction. During installation, the various power supply components are first installed in the main frame of the power supply box, then the end caps are installed at both ends of the main frame 1, and the wires connecting the components are embedded in the cable routing grooves 7. Finally, the top cover is installed. This facilitates the installation and removal of the wires.
[0035] Furthermore, the end cap panel 31 is provided with a potentiometer hole 8, and a waterproof rubber plug 9 is provided in the potentiometer hole 8 to improve waterproof performance.
[0036] Furthermore, the waterproof rubber stopper 9 includes a stopper body 91, a potentiometer mounting groove 92 at one end of the stopper body 91, a stopper through hole 93 at the other end of the stopper body 91 and communicating with the potentiometer mounting groove 92, and a stopper groove 94 on the periphery of the stopper body 91. The edge of the potentiometer hole 8 falls into the stopper groove 94. The stopper groove 94 includes two opposing groove walls 941, which respectively abut against the inner and outer sides of the end cap panel 31. This provides better waterproofing performance.
[0037] Specifically, the waterproof rubber stopper 9 has a stopper clearance groove 10 at one end near the stopper through hole 93. A connecting rubber strip 13 extends along the edge of the groove wall 941 along the stopper clearance groove 10. The end of the connecting rubber strip 13 away from the stopper clearance groove 10 has a stopper sealing part 14 for sealing the stopper through hole 93. The stopper sealing part 14 has an opening protrusion 15. It is easy to use and has good waterproof performance.
[0038] More specifically, the top cover 2 has first hooks 161 on both sides of its edge that engage with the main frame 1, and the side plate 12 has second hooks 162 at its engagement position with the top cover 2 that are compatible with the first hooks 161. The engagement of the top cover 2 and the main frame 1 is achieved through the interlocking action of the first hooks 161 and the second hooks 162, making assembly and disassembly convenient. In addition, the side plate 12 has heat dissipation fins 17 on its outer side to improve heat dissipation performance.
[0039] Furthermore, the two positioning mounting posts 41 are provided with circuit board connection holes 18 for mounting circuit boards, which is a reasonable structure.
