[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] Currently, the original grounding modes of waterproof power supplies on the market are all point-to-point wiring or point-to-point welding. There is always only one point of contact. In an environment with time, space and harsh temperature changes, there is a risk of poor grounding. The point-to-point wiring mode also destroys the sealing effect of the waterproof power supply.

[0037] In this regard, the present invention proposes a waterproof power supply, which can effectively improve the above-mentioned problem.

[0038] Refer to the following Figures 1 to 3 A waterproof power supply according to an embodiment of the present invention is described.

[0039] The waterproof power supply of the embodiment of the present invention includes: a housing 100 , a mounting portion 200 , and a clamping member 400 .

[0040] The housing 100 is open at both ends along its length. End caps 110 are connected to each of the two open ends along its length, sealing the housing 100 to form a sealed cavity. In this embodiment, the housing 100 has a rectangular structure. Furthermore, one end cap 110 is provided with an input interface, and the other end cap 110 is provided with an output interface. Both input and output interfaces are sealed and waterproof. This is a conventional arrangement in the prior art, and the present invention does not provide any technical improvements thereto, so further explanation is omitted here.

[0041] The mounting portion 200 is disposed within the housing 100 and has a first mating surface 201 and a second mating surface 202. The first mating surface 201 is configured to mate with one inner wall of the housing 100 in the width direction, and the second mating surface 202 is configured to mate with one inner wall of the housing 100 in the thickness direction. A power module assembly 300 is mounted on the mounting portion 200. The power module assembly 300 includes a PCB and electronic components mounted on the PCB. Both the housing 100 and the mounting portion 200 are constructed of conductive materials. Grounding is achieved by the first mating surface 201 and the second mating surface 202 mate with the inner wall of the housing 100, resulting in a large contact area. In this embodiment, both the housing 100 and the mounting portion 200 are constructed of aluminum.

[0042] The clamping member 400 is arranged in the shell 100. The clamping member 400 is used to apply force to the mounting portion 200 to keep the first mating surface 201 close to the inner wall of the shell 100, so that the first mating surface 201 and the inner wall of the shell 100 are firmly and stably attached together to ensure firm and stable grounding.

[0043] When assembling the waterproof power supply, place the mounting part 200 (with the power module assembly 300 installed) into the shell 100, so that the first mating surface 201 is in contact with the inner wall of one side of the shell 100 in the width direction, and the second mating surface 202 is in contact with the inner wall of one side of the shell 100 in the thickness direction. Use the clamping piece 400 to make the first mating surface 201 close to the inner wall of the shell 100. When the first mating surface 201 is in contact with the inner wall of the shell 100, due to the action of friction, the mounting part 200 will not move at will, and it can also ensure that the second mating surface 202 has good contact with the inner wall of the shell 100. Then, cover one of the end covers 110, fill the shell 100 with glue, and finally cover the other end cover 110 to complete the packaging. Through the above-mentioned structural setting, the original point-to-point wiring or point-to-point welding grounding mode is changed, and a surface-to-surface grounding mode is adopted, and the clamping piece 400 is used for clamping, which can avoid the risk of poor contact, and the grounding is firm and stable without destroying the sealing of the waterproof power supply. The overall sealing of the structure is good.

[0044] Reference Figure 1 and Figure 2As shown, in some embodiments of the present invention, the mounting portion 200 is provided with a third mating surface 203, the first mating surface 201 and the third mating surface 203 are respectively located on opposite sides of the mounting portion 200 along the width direction of the housing 100, and the clamping member 400 is at least partially inserted on the side of the third mating surface 203 away from the first mating surface 201, and the clamping member 400 abuts against the third mating surface 203 and the inner wall of the housing 100 on opposite sides along the width direction of the housing 100, thereby applying a force to the mounting portion 200 to keep the first mating surface 201 close to the inner wall of the housing 100, by making the clamping member 400 at least partially inserted on the side of the third mating surface 203 away from the first mating surface 201. 01, which facilitates assembly. Specifically, when assembling the waterproof power supply, the mounting portion 200 (with the power module assembly 300 installed) is placed into the housing 100, so that the first mating surface 201 is in contact with the inner wall of one side of the housing 100 in the width direction, and the second mating surface 202 is in contact with the inner wall of one side of the housing 100 in the thickness direction. Then, the clamping member 400 is inserted into the side of the third mating surface 203 facing away from the first mating surface 201, so that the clamping member 400 abuts the third mating surface 203 and the inner wall of the housing 100 on opposite sides along the width direction of the housing 100, thereby clamping the mounting portion 200 and ensuring that the first mating surface 201 is tightly fitted with the inner wall of the housing 100. Specifically, in this embodiment, the mounting portion 200 is configured as a U-shaped plate structure, and the third mating surface 203 is arranged parallel to the first mating surface 201.

[0045] Reference Figure 1 and Figure 2 As shown, in some embodiments of the present invention, two clamping members 400 are provided, which are respectively located on opposite sides of the mounting portion 200 along the length direction of the shell 100, so as to ensure the clamping effect of the clamping member 400 on the mounting portion 200. When assembling the waterproof power supply, the mounting portion 200 (with the power module assembly 300 installed) is placed into the shell 100, so that the first mating surface 201 is in contact with the inner wall of one side in the width direction of the shell 100, and the second mating surface 202 is in contact with the inner wall of one side in the thickness direction of the shell 100. Then, one of the clamping members 400 is inserted into the side of the third mating surface 203 away from the first mating surface 201. At this time, the mounting portion 200 will have a slight displacement along the length direction of the shell 100. Then, the other clamping member 400 is inserted from the other end into the side of the third mating surface 203 away from the first mating surface 201. At this time, the mounting portion 200 can be completely clamped by the two clamping members 400, firmly and reliably.

[0046] Reference Figure 1 and Figure 3As shown, in one embodiment of the present invention, the clamping member 400 includes a first plate 410 and a second plate 420. The second plate 420 is connected to one end of the first plate 410 and is arranged at an obtuse angle to the first plate 410. The second plate 420 and the first plate 410 are integrally bent. When the clamping member 400 is inserted between the third mating surface 203 and the inner wall of the housing 100, the clamping member 400 can be deformed, thereby applying a force to the mounting portion 200. In this embodiment, the clamping member 400 is made of aluminum.

[0047] It is understandable that the clamping member 400 may also adopt other structural forms, for example, referring to Figure 4 and Figure 5 As shown, in another embodiment of the present invention, the clamping member 400 includes a first plate 410 and a second plate 420, the second plate 420 is connected to one end of the first plate 410 and is distributed at an acute angle to the first plate 410, that is, a V-shaped structure is formed between the first plate 410 and the second plate 420, and the second plate 420 and the first plate 410 are bent integrally. When the clamping member 400 is inserted between the third mating surface 203 and the inner wall of the shell 100, the two side edges of the first plate 410 and the second plate 420 that are facing away from each other are respectively abutted against the third mating surface 203 and the inner wall of the shell 100.
