[0038] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] This embodiment provides a communication device installation system, including a fastener 13 and a communication device 100 for a photovoltaic inverter. When wall-mounting is required, the communication device 100 for the photovoltaic inverter is installed on a wall 200 through a fixing member 12 or a protrusion, or can be installed on a mounting plate. More specifically, the fixing member is a screw. There are two screws, which are arranged side by side on the wall 200 or the mounting plate.

[0040] Furthermore, the communication device is used for collecting inverter working information and energy dispatch management. It is usually placed indoors and connected to the photovoltaic inverter via a network cable. Specifically, it can be placed on a desktop or mounted on a wall by screws. The communication device can be an inverter supporting product such as a smart meter and a data collector.

[0041] Reference Figures 1 to 10 As shown, the communication device 100 includes a housing 1, and the housing 1 has two wall-hanging holes 11. The housing 1 is inserted into the wall-hanging holes 11 by screws to install the communication device 100 on a wall 200. The screw has a head and a shaft. Before the communication device is installed on the wall 200, the head and part of the shaft of the screw are exposed; when the communication device 100 is installed on the wall 200, the head and part of the shaft are inserted into the wall-hanging holes 11.

[0042] Furthermore, the communication device 100 further includes: a baffle 2, an internal support plate 3, an elastic member 4, a connecting member 7 and a guide sleeve 6. The elastic member 4 is located between the baffle 2 and the internal support plate 3. Figure 5 As shown, the elastic member 4 is fixedly connected to the baffle 2 and the internal support plate 3 by means of glue bonding or as shown in FIG. Fig. 9 and Fig.10 As shown, the elastic member 4 is connected to the baffle plate 2 and the internal support plate 3 respectively through the buckle 8, and the buckle 8 is integrally arranged with the baffle plate 3 and the internal support plate 3 respectively.

[0043] The communication device 100 has an initial state and a wall-mounted state. In the initial state, the baffle 2 blocks the wall-mounted hole 11; in the wall-mounted state, the elastic member 4 is compressed so that there is a space 5 between the baffle 2 and the wall-mounted hole 11 for the fixing member 12 to be inserted. The baffle 2 is used to prevent dust, insects and other debris from entering the interior of the device. In the initial state, the baffle 2 blocks the wall-mounted hole 11, that is, the wall-mounted hole 11 is not exposed to the atmosphere, which is not only aesthetically pleasing, but also can prevent insects from entering the interior of the product to avoid poor communication and malfunctions. From the wall-mounted state to the initial state, the elastic member 4 recovers, and the elastic force of the elastic member 4 causes the baffle 2 to block the wall-mounted hole 11. During this process, the baffle 2 can automatically discharge foreign matter such as dust, and no tools are required for cleaning.

[0044] Further, the connecting member 7 and the internal support plate 3 are fixedly connected by a fastener 13. Specifically, the fastener 13 is a screw. The connecting member 7 has a connecting groove, and the inner wall of the connecting groove is provided with an internal thread. The screw and the connecting member 7 are threadedly connected to fix the internal support plate 3 on the connecting member 7. There are two connecting members 7, which are arranged on both sides of the guide sleeve 6. The guide sleeve 6 and the connecting member 7 are integrally arranged or fixedly connected. Specifically in this embodiment, the guide sleeve 6 and the connecting member 7 are integrally arranged. In other embodiments, the guide sleeve 6 and the connecting member 7 can be fixedly connected by welding or the like.

[0045] The inner support plate 3 has a lug portion 31, and the lug portion 31 has a through hole 311 for inserting the fastener 13. In the wall-mounted state, the fastener 13 is inserted into the through hole 311 and is threadedly connected to the connector 7. The baffle 2 has a first pressing portion 21 and a second pressing portion 22, and the area of ​​the second pressing portion 22 is larger than the area of ​​the first pressing portion 21. The elastic member 4 is connected to the second pressing portion 22. When the communication device 100 is installed on the wall, the head of the screw first contacts the second pressing portion 22, and the second pressing portion 22 is pressed along the first direction, where the "first direction" refers to the length direction of the elastic member 4. When the head of the screw enters the interior of the wall-mounted hole 11, the mobile communication device 100 is moved so that the head of the screw contacts the first pressing portion 21.

[0046] The guide sleeve 6 has a guide groove 61, and the baffle 2 can be movably arranged in the guide groove 61 along the first direction. The depth of the guide groove 61 is 15-25mm. Specifically in this embodiment, the depth of the guide groove 61 is 20mm. The guide groove 61 can not only play a guiding role, but also play a certain protective role on the elastic member 4. More specifically, the elastic member 4 is a spring. Under the action of the spring, the communication equipment of this embodiment can have a larger space 5 compared with the prior art, and can be compatible with the heads of screws of different shapes, and has a wider adaptability.

[0047] When assembling the communication device of this embodiment, the spring is first connected to the baffle 2 and the internal support plate 3 by means of snaps or glue, and then installed into the interior of the housing 1, and the internal support plate 3 is fixedly connected by screws and connectors 7. When the communication device 100 is installed on the expansion screws on the wall 200, the spring will be elastically deformed due to the compression of the baffle 2 by the head of the screw, and the baffle 2 will slide in the first direction along the guide groove 61. In order to make the sliding of the baffle 2 smoother, grease can be applied in the guide groove 61. Then the entire device can be installed to the corresponding position along the wall hanging hole 11. When the communication device is removed from the wall, due to the elastic force of the spring, the baffle 2 returns to a position flush with the outer surface of the device along the guide groove 61, and the hole position cannot be seen in appearance. In this process, the baffle 2 will actively push out the dirt in the wall hanging hole 11 to achieve self-cleaning, and no tools are needed. At the same time, when the communication device 100 does not use the wall hanging hole 11, the hole position cannot be seen from the appearance of the communication device, which improves the aesthetics.

[0048] The photovoltaic inverter communication device of this embodiment has at least the following advantages:

[0049] (1) The baffle can cover the wall-mounting hole, which improves the overall appearance of the equipment and prevents insects and other debris from entering the interior of the communication equipment;

[0050] (2) By setting the elastic member, the space can be adjusted, and it can be compatible with the heads of different types of screws, which has a wider applicability;

[0051] (3) When the communication equipment is removed from the wall, the baffle can push out dust and other debris inside the communication equipment, and has a self-cleaning function without the need for tools.
