[0002] With the development of industrial technology and the improvement of people's living standards, electricity usage scenarios are becoming more and more extensive. In outdoor scenarios, portable power modules are often used for power supply. In order to meet outdoor power demand, the power module needs to have outdoor use function. For high-power outdoor power modules, their high-power output will inevitably generate a lot of heat energy, which is easy to cause overheating problems. Therefore, a fan module needs to be set to dissipate heat. In outdoor scenarios, it must be ensured that the fan module has better waterproof performance. Therefore, the fan line often needs to be connected through a waterproof connector.

[0025] In the utility model, all fan wires are collected to the main terminal through the PCB board, and then connected to the waterproof connector through the adapter wire, so only one adapter wire and one waterproof connector are needed to complete the waterproof connection with the power supply; and because the potting glue is used to form a sealed waterproof structure including the PCB board, the fan terminal and the main terminal, the sealed waterproof function can be well achieved. Therefore, the utility model has a clever structural design, simple manufacturing, low cost and good waterproof effect.

[0026] Figure 1 It is a structural schematic diagram of the outdoor fan module of the utility model when no potting glue is poured into it. Figure 2 The utility model is a schematic diagram of the structure of the outdoor fan module when the potting glue is poured into the module. Figure 3 This is a structural schematic diagram of the outdoor fan module of the utility model when the potting glue is poured into it from another angle. Figure 1-3 The outdoor fan module of the utility model is described as follows.

[0027] like Figure 1-3 As shown, the outdoor fan module of the utility model includes a fan bracket 100, three fan groups 200 fixed in the fan bracket 100, a glue potting box assembly 300 arranged on the side of the fan bracket 100 facing away from the fan group 200, an adapter cable 400 and a waterproof connector 500.

[0028] like Figure 1As shown, the glue potting box assembly 300 includes a glue potting box 310, a PCB board 320 accommodated in the glue potting box 310, a fan terminal 330 and a main terminal 340 arranged on the PCB board 320. The number of the fan terminals 330 is equal to the number of the fan groups 200. For example, in the preferred embodiment shown in the utility model, three fan groups 200 correspond to three fan terminals 330. Of course, those skilled in the art know that, according to actual needs, more or less fan groups 200 and corresponding fan terminals 330 can be set. No matter how many fan groups 220 and fan terminals 330 are set, they will eventually be aggregated to a main terminal 340 through the PCB board 320.

[0029] like Figure 1 As shown, each fan terminal 330 is connected to the main terminal 340 through the PCB board 320; the main terminal 340 is connected to the adapter cable 400; the adapter cable 400 is connected to the power supply through the waterproof connector 500. Each fan group 200 includes two fans 210, and the fan line of each fan is connected to its corresponding fan terminal 330. Of course, those skilled in the art know that more or less fans can be set according to actual needs, as long as the fan lines of all fans in each fan group are connected to the same corresponding fan terminal 330.

[0030] The potting box assembly 300 further includes a potting glue 350 that wraps the PCB board 320, the fan terminal 330, and the main terminal 340. The potting glue 350 and the potting box 310 together form a sealed and waterproof structure. Figure 2 As shown, after the potting glue 350 is injected into the potting box 310 , the potting glue 350 completely wraps the PCB board 320 , the fan terminal 330 and the main terminal 340 , and forms a sealed and waterproof structure together with the potting box 310 .

[0031] In the utility model, all fan wires are collected to the main terminal through the PCB board, and then connected to the waterproof connector through the adapter wire, so only one adapter wire and one waterproof connector are needed to complete the waterproof connection with the power supply; and because the potting glue is used to form a sealed waterproof structure including the PCB board, the fan terminal and the main terminal, the sealed waterproof function can be well achieved. Therefore, the utility model has a clever structural design, simple manufacturing, low cost and good waterproof effect.

[0032] Further Figure 1As shown, the fan bracket 100 is an L-shaped bracket, and three fan groups 200 are arranged side by side in the L-shaped bracket, each fan group 200 includes two fans 210, and each fan 210 is fixed in the fan bracket 100 by screws 610. The glue potting box 310 is a rectangular box with an opening on one side. The glue potting box 310 is arranged on one side of the long side of the L-shaped bracket. The PCB board 320, the fan terminal 330 and the main terminal 340 are arranged on the inner wall of the glue potting box 310 facing the opening, and the main terminal 340 is arranged adjacent to one side end wall of the glue potting box 310; the potting glue 350 seals the opening.

[0033] like Figure 1 As shown, the fan terminal 330 includes a signal line terminal 331 and a power line terminal 332. The fan line of each fan 210 includes a signal line 211 and a power line 212. The power line 212 of the fan 210 of each fan group 200 is connected to the power line terminal 332 in the corresponding fan terminal 330; the signal line 211 of the fan of each fan group 200 is connected to the signal line terminal 331 in the corresponding fan terminal 330. The number of sockets included in each power line terminal 332 and signal line terminal 331 can be consistent with the number of fans in each fan group. That is, Figure 1 In the preferred embodiment shown, each fan group 200 includes two fans 210, so each power line terminal 332 and signal line terminal 331 respectively include two plug ports. In other preferred embodiments of the utility model, for example, each fan group 200 includes one fan 210, so each power line terminal 332 and signal line terminal 331 respectively include one plug port. For another example, each fan group 200 includes three fans 210, so each power line terminal 332 and signal line terminal 331 respectively include three plug ports.

[0034] Further Figure 2 As shown, a plurality of threading holes 110 are provided on one side of the fan bracket 100 where the glue potting box assembly 300 is installed, and the glue potting box assembly 300 is arranged to avoid the threading holes 110. Each threading hole 110 corresponds to one of the fan terminals 330 so that the power line 212 and the signal line 211 of the fan 210 corresponding to the fan terminal 330 pass through the threading hole 110 to connect the power line terminal 332 and the signal line terminal 331 in the corresponding fan terminal 330. Here, the glue potting box assembly 300 avoiding the threading hole 110 means that the glue potting box assembly 300 will not cover the threading hole 110 or will not completely cover the threading hole 110 so that the power line 212 and the signal line 211 pass through the threading hole 110. Further, as Figure 1-3As shown, a cable tie 410 is provided on the adapter cable 400 , a cable tie bridge 420 is provided on the fan bracket 100 , and the adapter cable 400 is fixed on the cable tie bridge 420 through the cable tie 410 .

After the three fan groups 200 are installed, the fan line of each fan group is connected to the same corresponding fan terminal 330, and then all the fan lines are aggregated to the main terminal 340 through the PCB board 320. Here, any known aggregation method in the art can be used to achieve the above aggregation, and those skilled in the art are aware of any suitable schemes and required devices. In order not to blur the invention point of the utility model, it is not described in detail here.

The adapter line 400 is fixed with a cable tie 410 through a cable bridge 420, which can prevent the adapter line 400 from shaking and affecting the glue quality. Finally, the potting glue 450 is poured into the potting box 310. After the potting glue 350 is injected into the potting box 310, the potting glue 350 completely wraps the PCB board 320, the fan terminal 330 and the main terminal 340, and forms a sealed waterproof structure together with the potting box 310. Through this structure, the signal lines and power lines of multiple fans can be aggregated into one adapter cable. The adapter cable has a waterproof connector. When in use, multiple fans can be connected by docking with the matching waterproof connector. There is only one line after the adapter, and waterproofing is simple.

[0036] In the utility model, all fan wires are collected to the main terminal through the PCB board, and then connected to the waterproof connector through the adapter wire, so only one adapter wire and one waterproof connector are needed to complete the waterproof connection with the power supply; and because the potting glue is used to form a sealed waterproof structure including the PCB board, the fan terminal and the main terminal, the sealed waterproof function can be well achieved.
