They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "assembly," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The following is combined with Figures 1 to 6 This invention describes a waterproof and dustproof power supply housing according to an embodiment of the present invention, comprising a main housing 1, side covers 2, a top cover 3, and wires 4. The side covers 2 are respectively installed at the left and right ends of the main housing 1, and the top cover 3 is installed at the top of the main housing 1. The wires 4 are installed on the side covers 2.

[0034] The upper cover 3 and the main housing 1 are fastened together, and a sealing structure is provided at the connection between the wire 4 and the side cover 2;

[0035] The side cover 2 and the main housing 1 are snapped together, and the connection between the side cover 2 and the main housing 1 is welded together. The interior of the main housing 1 is filled with insulating colloid for sealing the circuit board.

[0036] The waterproof and dustproof power supply casing is constructed by first sealing the wire 4 to the side cover 2, then snapping the side cover 2 to the main housing 1 and welding them together. Next, insulating grease for sealing the circuit board is injected into the interior of the main housing 1. Finally, the top cover 3 is fastened to the main housing 1 to form a waterproof and dustproof integrated structure. Thus, the side cover 2 and the main housing 1 are fixed together by both welding and snap-fitting, eliminating the need for additional waterproof gaskets, multiple screws, and other parts. This optimizes the waterproof and dustproof structure, reduces the number of components, facilitates assembly, and saves on material and processing costs.

[0037] Furthermore, such as Figures 3 to 5 As shown, the front and rear sides of the interior of the main housing 1 are provided with protrusions 11. The protrusions 11 are located close to the inner bottom surface of the main housing 1 and form a first groove 111 between them and the inner bottom surface of the main housing 1.

[0038] The side cover 2 has a first locking block 21 at its bottom on the side facing the main housing 1. The first locking block 21 engages with the corresponding first locking groove 111. Thus, during installation, the first locking block 21 of the side cover 2 is inserted into the first locking groove 111 of the main housing 1 to achieve a locking and fixing between the side cover 2 and the main housing 1, facilitating subsequent welding processes.

[0039] Specifically, the contact surfaces of the first locking block 21 and the protrusion 11, the contact surface of the first locking block 21 and the main housing 1, and the contact surface of the side cover 2 and the main housing 1 are all welded parts 10. This forms multiple welded parts 10 between the side cover 2 and the main housing 1, effectively preventing water and dust damage.

[0040] Furthermore, such as Figure 3 As shown, the first locking block 21 extends towards the center of the side cover 2, and the first locking block 21 protrudes from the first locking groove 111 towards the center of the side cover 2. This increases the contact area between the first locking block 21 and the main housing 1, making the locking more secure. During welding, the welding area between the first locking block 21 and the main housing 1 can also be increased, resulting in a more secure weld.

[0041] Specifically, the protrusion 11 extends through both ends of the main housing 1, and the protrusion 11 is parallel to the inner bottom surface of the main housing 1. Thus, the protrusion 11 also serves to support and fix the circuit board, allowing the circuit board to be placed between two protrusions 11.

[0042] In some embodiments, such as Figure 1 , Figure 2 As shown, the top of the side cover 2 extends horizontally outward to form a first mounting part 22, and both the left and right ends of the top cover 3 extend horizontally outward to form a second mounting part 31. The first mounting part 22 and the second mounting part 31 correspond one-to-one vertically.

[0043] The first mounting part 22 has a second slot 23 that extends vertically, and the bottom surface of the second mounting part 31 has a downwardly protruding second locking block 32, which engages with the corresponding second slot 23. Thus, during installation, the second locking block 32 of the upper cover 3 is inserted into the second slot 23 of the side cover 2, achieving a snap-fit ​​fixation between the side cover 2 and the upper cover 3. Assembly is simple and requires no additional parts.

[0044] In other embodiments, such as Figure 5 As shown, the main housing 1 has buckles 12 on both the front and rear sides of its outer surface, and the upper cover 3 has barbs 33 on both the front and rear sides that are adapted to the buckles 12. The barbs 33 and the buckles 12 are engaged. Thus, during installation, the barbs 33 of the upper cover 3 are inserted into the buckles 12 of the main housing 1 to achieve the engagement and fixation of the main housing 1 and the upper cover 3. The assembly is simple and requires no additional parts.

[0045] It should be noted that, as Figure 3 As shown, the top of the side cover 2 has a connection port 24, and the sheath of the wire 4 is formed with a sealing element 41. The wire 4 communicates with the interior of the main housing 1 through the connection port 24, and the sealing element 41 is installed on the connection port 24 and seals the connection port 24.

[0046] The sealing piece 41 seals the connecting port 24, realizes the sealed installation between the wire 4 and the side cover 2, and is integrally formed on the sheath of the wire 4, so that no additional waterproof ring is needed, the parts are reduced, the assembly is easy, and the material and processing costs are saved.

[0047] Further, as shown in the drawings, the middle ring of the sealing piece 41 is provided with a sealing groove 411 matched with the connecting port 24, the sealing groove 411 and the edge of the connecting port 24 are fitted, and the two sides of the sealing groove 411 are respectively formed with a first sealing part 412 and a second sealing part 413. Figure 6

[0048] The first sealing part 412 is located on the side of the side cover 2 facing the main shell 1, the second sealing part 413 is located on the side of the side cover 2 away from the main shell 1, and the first sealing part 412 and the second sealing part 413 tightly seal the connecting port 24.

[0049] Therefore, after sliding into the connecting port 24 through the sealing groove 411 and being fitted with the connecting port 24, the first sealing part 412 and the inner surface of the side cover 2 are tightly abutted, the second sealing part 413 and the outer surface of the side cover 2 are tightly abutted, the connecting port 24 is tightly wrapped, and the sealing performance of the connecting port 24 is better.

[0050] It should be noted that the sealing piece 41 is made of elastic insulation material. Based on the fact that the side cover 2 in contact with the sealing piece 41 needs to be tightly abutted to improve the sealing performance, the sealing piece 41 is preferably made of elastic insulation material, which can be used as a wire sheath and can be tightly abutted by using elasticity, such as silicone, rubber and the like.

[0051] The technical principles of the utility model are described above in combination with specific embodiments. These descriptions are only for explaining the principles of the utility model, and cannot be interpreted as limiting the protection scope of the utility model in any way. Based on the explanations herein, other specific embodiments of the utility model can be conceived by those skilled in the art without creative labor, and these embodiments will all fall within the protection scope of the utility model.​
