[0035] Glossary:

[0036] A printed circuit board (PCB) is a flat board made of insulating material. The board surface is used to layout and connect electronic components through structures such as conductive tracks, holes and pads. The main function of a PCB is to provide electrical connections and mechanical support between electronic components. It can accommodate electronic components such as integrated circuits, resistors, capacitors and connectors, and connect them through wires or rails. The PCB also provides a stable physical support structure to ensure that electronic components can be safely installed in it, hereinafter referred to as "PCB board".

[0037] Bluetooth is a short-range wireless communication technology that allows devices to communicate data and voice over short distances.

[0038] This embodiment provides a communication box body, see Figure 1-Figure 8 As shown, the communication box body is used to install the communication module, and the communication box body includes an upper shell 1 and a base plate 2. The upper shell 1 is a streamlined structure that is narrow at the top and wide at the bottom. Two fixing frames 21 and waterproof connector holes 22 are provided on the base plate 2. The two fixing frames 21 are symmetrically arranged on both sides of the waterproof connector holes 22. The fixing frames 21 are used to fix the communication module, and the upper shell 1 is connected to the base plate 2.

[0039] In this embodiment, the communication box body is used to install the communication module, and the communication module includes a PCB board, wherein the PCB board is integrated with a Bluetooth communication module. The upper shell 1 in this embodiment is installed on the bottom plate 2, so that the upper shell 1 is connected to the bottom plate 2 to form a sealed space environment. Installing the communication module in this space can prevent the communication module and related accessories in the box body from being invaded by rain and wind and sand. In addition, the closed environment can prevent the circuit equipment and electronic components in the box body from being fully in contact with the external air, slowing down the speed of oxidation damage of electronic accessories and equipment, so as to reduce the cost of later equipment maintenance and replacement. Specifically, two fixing frames 21 are provided on the bottom plate 2, and the communication module is installed between the two fixing frames 21 to limit and fix the communication module. For example, the two fixing frames 21 can clamp the bottom sides of the PCB board of the communication module between the two fixing frames 21 to improve the stability of the installation of the PCB board. A waterproof connector hole 22 is provided between the two fixing frames 21 on the bottom plate 2. The waterproof connector hole 22 is used to connect a waterproof connector. The circuit in the waterproof connector is electrically connected to the PCB board of the communication module, and is used to provide the PCB board with operating power or information transmission. The waterproof connector has waterproof sealing properties, which can prevent moisture, dust and other external substances from entering the box body, thereby protecting the electronic components inside the box body from damage. Moreover, the upper shell 1 in this embodiment is a streamlined structure with a narrow top and a wide bottom. Dust and rain can slide down the streamlined upper shell 1, which can avoid the accumulation and invasion of rain and dust on the box body, thereby delaying the aging of the components inside the box body and preventing the internal components from being damaged by external dust and rain.

[0040] In one embodiment of the present application, see Figure 2 and Figure 5 As shown, the tops of the two fixing frames 21 are respectively provided with mounting slots 211 , and the two mounting slots 211 are used for fixing and installing the communication modules.

[0041] In this embodiment, in order to ensure the stability of the PCB board in the box body, the tops of the two fixing frames 21 are respectively provided with mounting notches 211. Figure 2 For example, during installation, both sides of the bottom end of the PCB board are inserted into the installation slots 211. The installation slots 211 play a role in fixing and limiting the PCB board, thereby improving the stability of the PCB board in the box body.

[0042] In one embodiment of the present application, a cushion block is disposed in the installation slot 211 .

[0043] In this embodiment, in order to further ensure the stability of the PCB board in the box body, the top of the PCB board needs to vertically abut against the top of the inner cavity of the upper shell 1 to prevent the PCB board from shaking in the box body. However, there are differences in the vertical dimensions of the PCB boards. The height of some PCB boards is not enough to abut against the top of the inner cavity of the upper shell 1. At this time, it is necessary to place a pad in the installation groove 211 to raise the bottom position of the PCB board, so that the PCB board can abut against the top of the inner cavity of the upper shell 1, thereby improving the adaptability of the PCB board installation in the box body and the stability of the PCB board after installation.

[0044] In one embodiment of the present application, see Figure 3 As shown, the top of the upper shell 1 is a flat top, and a card slot 11 is arranged on the inner side of the top of the upper shell 1 .

[0045] In this embodiment, the top of the upper shell 1 is flat so that the top of the PCB board can abut against the top of the inner cavity of the upper shell 1.

[0046] Furthermore, in order to improve the stability of the contact between the top of the PCB board and the top of the inner side of the upper shell 1, a card slot 11 is provided on the inner side of the top of the upper shell 1. The card slot 11 limits the top of the PCB board, thereby improving the stability of the PCB board installed in the box body.

[0047] In one embodiment of the present application, see Figure 5 and Figure 6 As shown, a circle of bosses 23 are provided on the upper end surface of the bottom plate 2 , and a sealing groove 12 is provided on the lower end surface of the upper shell 1 .

[0048] In this embodiment, the boss 23 provided on the upper end surface of the bottom plate 2 is plugged into the sealing groove 12 on the lower end surface of the upper shell 1, thereby realizing a stable connection between the upper shell 1 and the bottom plate 2. The plugging and matching of the sealing groove 12 and the boss 23 can increase the connection contact area between the upper shell 1 and the upper end surface of the bottom plate 2, thereby improving the sealing of the connection between the upper shell 1 and the bottom plate 2. Further, in order to improve the sealing effect, a sealant can be injected between the boss 23 and the sealing groove 12, thereby further improving the waterproof sealing of the connection between the upper shell 1 and the bottom plate 2, so as to be suitable for the field of photovoltaic power generation and communication, especially in the scene where the waterproof sealing is required for a long time in the outdoor environment.

[0049] In one embodiment of the present application, see Figure 7 and Figure 8 As shown, the outer wall of the upper shell 1 is provided with a mounting wing 3, the mounting wing 3 is provided on a wide surface of the upper shell 1 and extends to surround both sides of the upper shell 1, and the connection between the mounting wing 3 and the streamlined upper shell 1 is a tangent curved surface.

[0050] In this embodiment, optionally, the mounting wing 3 is integrally formed with the upper shell 1, and a threaded hole is opened on the mounting wing 3, and the threaded hole cooperates with bolts to install the box body on a photovoltaic bracket or photovoltaic equipment, which is convenient for flexible disassembly and assembly and firm installation, and the connection between the mounting wing 3 and the streamlined structure of the upper shell 1 is a tangent surface, which can prevent rainwater and dust from accumulating and invading the outside of the box body.

[0051] In one embodiment of the present application, see Figure 1 , Figure 2 , Figure 5 and Figure 8 As shown, buckles 4 are respectively provided on both sides of the bottom plate 2 , and the bottom plate 2 is connected with the corresponding vertical plates 41 on the side walls of the upper shell 1 by means of the buckles 4 .

[0052] In this embodiment, the upper shell 1 and the bottom plate 2 connected together are further fixedly connected by means of a hook-and-match connection between the buckle 4 and the corresponding vertical plate 41 on the side wall of the upper shell 1. On the one hand, the buckle 4 can play an auxiliary fixing role between the upper shell 1 and the bottom plate 2, thereby improving the stability of the connection between the upper shell 1 and the bottom plate 2. On the other hand, when the upper shell 1 and the bottom plate 2 are sealed by injection, the volatile components in the sealant material will release gas during the curing process, causing the sealant to expand in volume when drying. The buckle 4 can play a fixing role after injection to prevent the sealant from expanding in volume and bouncing up the upper shell 1 and separating it from the bottom plate 2, thereby improving the tightness of the connection between the upper shell 1 and the bottom plate 2.

[0053] In one embodiment of the present application, see Figure 5 As shown, the buckles 4 on both sides of the bottom plate 2 are asymmetrically distributed.

[0054] In this embodiment, the buckles 4 on both sides of the base plate 2 are asymmetrically distributed, which can be used to remind the installer of the different positions on both sides of the base plate 2 and prevent the installer from reversing the connection position between the upper shell 1 and the base plate 2, which is beneficial to improving installation efficiency.

[0055] In one embodiment of the present application, see Figure 2 and Figure 4 As shown, a light guide column hole 5 is provided on the base plate 2 and directly below the fixing frame 21 , a light guide column 51 is inserted into the fixing frame 21 , one end of the light guide column 51 is arranged at the top of the fixing frame 21 , and the other end of the light guide column 51 is arranged at the light guide column hole 5 .

[0056] In this embodiment, an indicator light is provided on the PCB board, and the light guide column 51 is used to transmit the indicator light in the box body to the outside of the box body through the light guide column hole 5 on the bottom plate 2, so that the staff can timely understand the working status of the PCB board in the box body.

[0057] An embodiment of the present application further provides a communication box, comprising a communication box body provided in any of the above embodiments of the present application and a communication module fixedly mounted on the fixing frame 21 .

[0058] The following is an example of a use process of a communication box provided by an embodiment of the present application: the upper shell 1 is a streamlined structure that is narrow at the top and wide at the bottom. Two fixing frames 21 are arranged on the bottom plate 2. The fixing frames 21 are used to limit and fix the communication module. The two fixing frames 21 can clamp the PCB board of the communication module between the two fixing frames 21. A waterproof connector hole 22 is opened between the two fixing frames 21. The waterproof connector hole 22 is used to connect the waterproof connector. The circuit in the waterproof connector is electrically connected to the PCB board to provide the PCB board with operating power or information transmission, thereby realizing the communication process. The upper shell 1 is connected to the bottom plate 2, so that the upper shell 1 and the bottom plate 2 are combined to form a sealed space environment in the box body, which can prevent the communication module and related accessories in the box body from being invaded by rain and wind and sand. In addition, the closed environment can prevent the circuit equipment and electronic components in the box body from being fully in contact with the external air.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it.
