[0034] As shown in Figures 1-6, this utility model provides a power supply housing, comprising:
[0035] The first housing 1 and the second housing 2 are connected by a snap-fit structure. The complementary snap-fit parts enable rapid assembly and positioning, reducing the difficulty of manual alignment.
[0036] The first housing 1 includes:
[0037] A first enclosure 19 perpendicular to the bottom surface of the first housing and a first baffle 17 connected to the first enclosure 19, wherein the length of the first baffle 17 is greater than that of the first enclosure 19.
[0038] First support columns 13 are distributed at the four corners of the rectangular area formed by the first enclosure 19 and the first baffle 17;
[0039] A first snap-fit element 15 is located inside the first enclosure panel 19;
[0040] The light-transmitting panel 6 and the button 7 are located on the front of the housing;
[0041] The second housing 2 includes:
[0042] A second enclosure 20 perpendicular to the bottom surface of the second housing and a second baffle 18 connected to the second enclosure 20. The length of the second baffle 18 is less than that of the second enclosure 20. The second enclosure 20 is provided with a second reserved groove. The second reserved groove 24 and the first reserved groove 23, after being assembled, form a first reserved hole 25 that allows the connecting line 3 to pass through.
[0043] Second support columns 14 are distributed at the four corners of the rectangular area formed by the second enclosure 20 and the second baffle 18;
[0044] A second snap-fit member 16 is located inside the second enclosure 20 and is complementary to and fitted with the first snap-fit member 15;
[0045] The upper and lower ends of the housing have lugs 9 and grooves 4 on both sides. The grooves 4 are provided with slots 5 and the lugs are provided with mounting holes.
[0046] The first support column 13 and the second support column 14 are axially aligned when the shells are connected, forming a continuous support structure.
[0047] The first housing 1 and the second housing 2 are connected by a snap-fit structure. The complementary snap-fit parts enable quick assembly and positioning, reducing the difficulty of manual alignment. The concave-convex fit of the first snap-fit part 15 and the second snap-fit part 16 ensures that the contact surface is not offset, improves the sealing performance, reduces the reliance on assembly tools, and is suitable for scenarios with frequent disassembly and assembly.
[0048] The first support column 13 and the second support column 14 are axially aligned to form a continuous support structure. The support columns are distributed at the four corners of the rectangular area to resist the bending deformation of the shell when subjected to external forces. After axial alignment, the threaded holes 10 inside the support columns form a continuous force channel, which can meet the requirements of bolt connection, improve the overall compressive strength of the shell, and is suitable for high-load scenarios such as energy storage equipment.
[0049] The first baffle 17 is longer than the first enclosure 19, and the second baffle 18 is shorter than the second enclosure 20, forming an asymmetrical covering structure. This facilitates staggered sealing when the shell is closed. The long baffle covers the edge of the short baffle, preventing external dust or liquid from entering and enhancing waterproof and dustproof performance. It is suitable for outdoor or industrial environments.
[0050] After the first housing 1 and the second housing 2 are assembled, the first enclosure 19 of the first housing 1 surrounds part of the second enclosure 20 to form a stepped nested structure, which increases the sealing performance.
[0051] The light-transmitting plate 6 and the button 7 are integrated on the front of the housing. The light-transmitting plate 6 provides an optical signal transmission path and is coupled to the internal LED light source. The button 7 is aligned with the PCB board 12 contacts.
[0052] The second housing 2 has a groove 4 with a slot 5 inside and lugs 9 at the top and bottom. The groove 4 is adapted to the guide rail of the external equipment. The lugs 9 and the mounting holes on the lugs 9 provide support points for suspension or bolt fixing. The slot 5 can be quickly locked with the buckle of the external module. The lugs 9 are adapted to various installation methods and support multiple installation scenarios such as wall mounting and embedded installation, thus expanding the compatibility of the equipment.
[0053] The second reserved hole 11 is opened on the first baffle 17 to accommodate external cables. The second reserved hole 11 provides a fixed channel for power input / output lines to avoid cable bending and wear. The diameter of the hole matches the sealing ring to prevent foreign objects from entering the housing, thus balancing the convenience of cable management with the integrity of the housing seal.
[0054] A removable waterproof plug 22 is provided at the top of the threaded hole 10. The waterproof plug 22 fills the gap after the bolt connection, blocking the liquid penetration path. The material of the waterproof plug 22 is interference-fitted with the threaded hole 10 to form a secondary seal, extending the life of internal components 47.
[0055] Radial reinforcing ribs 21 are provided at the connection between the second baffle 18 and the second enclosure 20. The reinforcing ribs 21 offset the stress concentration at the shell joint, prevent cracking, and optimize the force transmission path by radial distribution, reduce the risk of local deformation, improve the shell's impact resistance, and adapt to frequent vibration environments.
[0056] The prompt area 8 is located at the lower front of the first housing 1, distinguishing the input / output terminals. It uses symbols or text to identify interface functions, reducing the probability of misoperation, improving the accuracy of user operation, and meeting safety certification standards.
[0057] Referring to Figure 2, the first baffle 17 has a second reserved hole 11 for external cables to pass through, realizing the physical connection of signals inside and outside the device. For example, power lines, data lines, sensor cables, etc. are connected to the internal circuit board and external devices through this hole to ensure the integrity of system functions.
[0058] The first support column 13 and the second support column 14 are both provided with threaded holes 10. The first housing 1 and the second housing 2 are connected by bolts that pass through the threaded holes 10. The bolt connection provides rigid constraints, transforming the housing and the support column into an integral load-bearing structure.
[0059] Referring to Figure 2, the top of the threaded hole 10 is provided with a removable waterproof plug 22, which fills the gap between the threaded hole 10 and the bolt with elastic sealing material to prevent rainwater, dust, oil and other substances from entering, making it suitable for outdoor equipment.
[0060] Referring to Figure 3, a reinforcing rib 21 is provided at the connection between the second baffle 18 and the second enclosure 20 of the second housing 2.
[0061] By increasing the moment of inertia of the cross section in the connection area, the stiffener 21 can significantly improve the structural stiffness and resist bending or torsional deformation. When subjected to external impact or pressure, the stiffener 21 forms a supporting branch, distributing the load to a larger area and avoiding structural failure caused by single-point overload.
[0062] Referring to Figure 1, the lower front end of the first housing 1 is provided with a prompting area 8 for distinguishing between the output end and the input end.
