[0042] In the description of the present application, if the first, second, etc. are described for the purpose of distinguishing technical features, they cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the sequence of technical features indicated.

[0043] It should be noted that the terms such as setting, installing and connecting should be understood in a broad sense, and the skilled in the art can determine the specific meaning of the above terms in the utility model in combination with the specific content of the technical solutions.

[0044] The technical solutions of the utility model will be described clearly and completely in combination with the drawings. Obviously, the following described embodiments are part of the embodiments of the utility model, not all the embodiments.

[0045] The data communication between the photovoltaic inverter and external devices (such as computers, monitoring systems, cloud platforms, etc.) can be realized through the communication module. The circuit board of the communication module is provided with an interface part and a network port part. The interface part is used for connecting photovoltaic devices, and the network port part is used for connecting network cables. In the related art, because the interface part and the network port part have different sizes, the interface part and the network port part are directly connected to the circuit board, and there is a height difference between the two, which causes the opening position of the shell to be asymmetric, affecting the portability.

[0046] In order to reduce the height difference between the interface part and the network port part, the interface part is generally first sealed in the shell of the communication module, then the circuit board and the interface part are connected through wires, and then the network port part is aligned with the interface part; the assembly process is complicated, and the connection through the wire harness is not reliable, which is prone to poor contact problems. The connection through the wire is not reliable and is prone to accidental breakage.

[0047] Referring to Figure 1 and Figure 2 The utility model discloses a circuit board of communication module, including first circuit board 110, second circuit board 120 and pad support piece 130, one side of first circuit board 110 is provided with network port part 111;Pad support piece 130 is connected to first circuit board 110;Second circuit board 120 is provided with interface part 121;Second circuit board 120 and network port part 111 are located on the same side of first circuit board 110, and second circuit board 120 is connected to pad support piece 130, to reduce the height difference of the axis of interface part 121 and the axis of network port part 111 in the thickness direction of first circuit board 110.

[0048] Second circuit board 120 and network port part 111 are located on the same side of first circuit board 110, and second circuit board 120 is connected to pad support piece 130, pad support piece 130 plays the role of pad height interface part 121 located in second circuit board 120, to reduce the height difference of the axis of interface part 121 and the axis of network port part 111 in the thickness direction of first circuit board 110, which is beneficial to the symmetry of the opening position of the shell of the communication module;First circuit board 110 supports network port part 111, and second circuit board 120 supports interface part 121. When assembling, first circuit board 110 and second circuit board 120 are directly connected through pad support piece 130, and the assembly process is simple.

[0049] In some embodiments, in the thickness direction of the first circuit board 110, the height difference between the axis of the interface portion 121 and the axis of the network port portion 111 is less than or equal to half the height of the network port portion 111. That is, the height difference between the axis of the interface portion 121 and the axis of the network port portion 111 is within a certain range, so as to limit the distance between the axis of the interface portion 121 and the axis of the network port portion 111, so that the openings of the housing of the communication module are symmetrically arranged, and the user can intuitively distinguish the differences between different ports. When facing multiple ports such as the interface portion 121 and the network port portion 111, the user can more easily identify the ports.

[0050] In some embodiments, the padding member 130 and the mesh port portion 111 are located on the same side of the first circuit board 110 so as to increase the height of the interface portion 121 by means of the padding member 130, thereby reducing the height difference between the axis of the interface portion 121 and the axis of the mesh port portion 111 in the thickness direction of the first circuit board 110.

[0051] Reference Figure 1 and Figure 2 As shown, in some embodiments, along the thickness direction of the first circuit board 110, the orthographic projection surface of the first circuit board 110 and the orthographic projection surface of the second circuit board 120 at least partially overlap; the padding member 130 includes a support portion 131, which is located at the overlapping position between the first circuit board 110 and the second circuit board 120, and connects the first circuit board 110 and the second circuit board 120 through the support portion 131. The support portion 131 can limit the distance between the first circuit board 110 and the second circuit board 120 to raise the height of the mesh port portion 111, thereby reducing the height difference between the mesh port portion 111 and the interface portion 121.

[0052] Along the thickness direction of the first circuit board 110, the orthographic projection surface of the first circuit board 110 and the orthographic projection surface of the second circuit board 120 at least partially overlap, which facilitates the placement of the first circuit board 110 and the second circuit board 120 on opposite sides of the support member 130, so as to maximize the contact area between the support member 130 and the first circuit board 110 and the second circuit board 120 while keeping the volume of the support member 130 unchanged, thereby improving the strength of the connection.

[0053] Reference Figure 1 and Figure 2As shown, in some embodiments, the height H1 of the support portion 131 in the thickness direction of the first circuit board 110 is greater than or equal to the distance between the center position of the net port portion 111 and the first circuit board 110, so that the interface portion 121 is under the pad support of the support portion 131, and the height difference between the axis of the interface portion 121 and the axis of the net port portion 111 is less than or equal to half the height of the net port portion 111. Since the thickness of the interface portion 121 itself is small, if the height of the support portion 131 in the thickness direction of the first circuit board 110 is less than the distance between the center position of the net port portion 111 and the first circuit board 110, the height of the interface portion 121 may not be sufficient, resulting in a height difference between the interface portion 121 and the net port portion 111 on the first circuit board 110.

[0054] Referring to Figure 1 and Figure 2 As shown, in some embodiments, the pad support 130 further comprises a connecting pin 132, one end of the connecting pin 132 is electrically connected with the first circuit board 110, and the other end is electrically connected with the second circuit board 120 through the support portion 131; through the connecting pin 132, the electrical connection between the first circuit board 110 and the second circuit board 120 is realized, and when connecting, only the connecting pin 132 needs to be inserted into the corresponding hole position of the first circuit board 110 or the second circuit board 120, which is convenient for disassembly and assembly; by connecting the first circuit board 110 or the second circuit board 120 through the connecting pin 132, the electrical connection and physical connection of the first circuit board 110 or the second circuit board 120 can be realized, which can ensure the stability of the connection between the first circuit board 110 or the second circuit board 120, and at the same time, the electrical connection between the first circuit board 110 and the second circuit board 120 can be realized without welding and wiring, reducing the assembly process and improving the overall assembly efficiency. The pad support 130 can be a board-to-board connector.

[0055] Referring to Figure 1 and Figure 2As shown in the drawings, in some embodiments, the plug-in direction of the interface part 121 is the same as the plug-in direction of the network port part 111, so that the user can more intuitively and conveniently operate when inserting or pulling out the communication module, reducing the risk of misplug and improving the portability of operation. The above arrangement makes the alignment between the network port part 111 and the interface part 121 higher, which is more conducive to arranging the network port part 111 and the interface part 121 on the center line of the communication module, thereby ensuring the structural stability of the communication module; if the interface part 121 is located on the center line of the communication module, the overall stress of the communication module will be more uniform when the interface part 121 is plugged, and at the same time, the overall shock resistance and stability of the communication module can be ensured; if the network port part 111 is located on the center line of the communication module, the network cable 400 connected with the network port part 111 is arranged along the center line of the communication module, which is more conducive to the layout of the line; the interface part 121 and the network port part 111 are located on the center line of the communication module, so that the user can more easily determine the plug-in direction, reducing the damage or poor contact caused by the wrong direction when plugging; further, the center line of the network port part 111 and the center line of the interface part 121 are located on the same straight line.

[0056] Referring to Figure 1 and Figure 2 As shown in the drawings, in some embodiments, along the thickness direction of the first circuit board 110, the interface part 121 is arranged staggered with the first circuit board 110, which is more conducive to the interface part 121 extending out of the shell 200 of the communication module for plugging in the case of reducing the material of the second circuit board 120 as much as possible, and can increase the distance between the network port part 111 and the interface part 121 in the length direction of the first circuit board 110, so that the network port part 111 and the interface part 121 are arranged corresponding to the opposite ends of the circuit board 100; the length of the first circuit board 110 is greater than the length of the second circuit board 120 in the length direction of the first circuit board 110, and the first circuit board 110 can carry the second circuit board 120 and other components (such as chips, etc.). Generally, the first circuit board 110 is located inside the shell 200, and since the second circuit board 120 is stacked on one side of the first circuit board 110, the interface part 121 is staggered with the first circuit board 110 at least partially, which can increase the size of the part of the interface part 121 extending out of the shell 200 as much as possible, which is more conducive to the plugging of the interface part 121; the interface part 121 can be completely staggered with the first circuit board 110, or partially staggered with the first circuit board 110, and the embodiments of the present application do not make special limitations thereon.

[0057] In the related art, in order to reduce the height difference between the interface part and the network port part, the interface part is directly fixed to the shell by means of pouring, the interface part is connected to the circuit board by wire harness, and the network port part is welded to one side of the circuit board and aligned with the interface part. One end of the wire harness is welded to the interface part, and the other end is welded to the circuit board. However, the connection by wire harness is not reliable, and the problem of poor contact is prone to occur. In the process of wiring the network port part or repairing the circuit board, the wire harness is prone to be pulled off.

[0058] Generally, the interface part 121 is a USB interface, and the network port part 111 is an Ethernet port. The interface part 121 is connected to the edge of the second circuit board 120, and the interface part 121 protrudes out of the circuit board 100, so that the interface part 121 is more easily aligned with the socket of the photovoltaic inverter, facilitating direct connection of the interface part 121 with the photovoltaic inverter and avoiding inconvenience caused by the interface part 121 being arranged in the middle of the second circuit board 120. In addition, arranging the interface part 121 at the edge of the second circuit board 120 reduces the overlapping area of the interface part 121 and the circuit board 100 in the thickness direction of the communication module, which is more conducive to heat dissipation.

[0059] Referring to Figure 1 and Figure 2 In some embodiments, the interface part 121 is connected to the edge of the second circuit board 120, and the second circuit board 120 is located in the extension direction of the axis of the interface part 121, so that the interface part 121 at least partially protrudes out of the first circuit board 110, facilitating the interface part 121 to be plugged with the photovoltaic inverter. The interface part 121 is connected to the circuit board 100 by welding, which directly fixes the interface part 121 to the circuit board 100, avoiding the problems of poor contact or looseness that may occur in the connection by wire harness, and the welding connection is more secure, which can provide more stable signal and power transmission and reduce faults caused by poor wiring. The wiring connection may be affected by factors such as frequent plugging and pulling, resulting in wear or poor contact at the connection, while the welding method is less prone to such problems and has high reliability. The welding method can reduce the complexity of wiring and simplify the production process.

[0060] Referring to Figure 1 and Figure 2As shown in the drawings, in some embodiments, the circuit board 100 further comprises a light blocking piece 140 and a plurality of display lights 150 arranged on the side of the first circuit board 110 away from the net port part 111; the light blocking piece 140 surrounds the display lights 150 to prevent the plurality of display lights 150 from light interference. The display lights 150 are used to display the state of the circuit board 100, for example, the display lights 150 can indicate that the circuit board 100 is in an open state, a working state or a networking state; the plurality of display lights 150 can indicate different states of the circuit board 100, and the light blocking piece 140 prevents light interference between the plurality of display lights 150, preventing the user from identifying different display lights 150 due to light interference; the shell 200 can be provided with a light transmission hole through which the display lights 150 can pass; glue can be applied to the light transmission hole to improve the waterproof effect.

[0061] Referring to Figure 1 and Figure 2 As shown in the drawings, in some embodiments, the light blocking piece 140 has a plurality of grooves 141, and parts of the display lights 150 are arranged in the grooves 141; the side walls of the grooves 141 can block part of the light of the display lights 150, effectively preventing light interference; in addition, the grooves 141 have positioning and fixing effects on the display lights 150, which is beneficial to assembly work; generally, the light blocking piece 140 is foam. In other embodiments, the light blocking piece 140 can also be a baffle arranged between different display lights 150.

[0062] Referring to Figure 1 and Figure 2 As shown in the drawings, in some embodiments, the circuit board 100 further comprises a button 160 arranged on the side of the first circuit board 110 away from the net port part 111; generally, the net port part 111 is arranged along the center line of the communication module, so that the first circuit board 110 is arranged close to the side wall of the shell 200; arranging the button 160 on the side of the first circuit board 110 away from the net port part 111 makes it easier to trigger the button 160, so as to control the communication module through the button 160; pressing the button 160 can turn on or off the communication module; the shell 200 is provided with a fixing hole corresponding to the button 160, and the fixing hole is provided with a soft rubber sleeve 224 sleeved on the button 160; the button 160 can be triggered by pressing the soft rubber sleeve 224, facilitating the operation of the button 160.

[0063] Referring to Figure 1The utility model discloses second aspect embodiment provides a kind of communication module, including shell 200 and the circuit board 100 of communication module of any embodiment of above-mentioned first aspect, circuit board 100 is set to the inside of shell 200;Shell 200 is provided with the line hole 221 and the aperture 235 of relative arrangement, interface portion 121 is at least partially crossed by aperture 235, so that interface portion 121 can be connected with photovoltaic inverter;Line hole 221 corresponds with network interface portion 111, so that network cable 400 is crossed by line hole 221 and is connected with network interface portion 111.

[0064] The circuit board 100 of the communication module has the beneficial effects of the above-mentioned embodiments, and the communication module accordingly has the beneficial effects of the above-mentioned embodiments, the specific implementation manner of which can be referred to the above-mentioned embodiments, and the present application will not be repeated here.

[0065] Refer to Figure 2 As shown in some embodiments, the communication module includes a circuit board 100 and a shell 200, the shell 200 has a receiving cavity 210 for accommodating the circuit board 100; the shell 200 includes a first shell 220 and a second shell 230, the first shell 220 is connected with the second shell 230 to form the receiving cavity 210; one of the first shell 220 and the second shell 230 is provided with a connecting portion 231, the connecting portion 231 is located in the receiving cavity 210 and is used for connecting the circuit board 100.

[0066] In the case of wiring or maintenance of the communication module, the first shell 220 and the second shell 230 are disassembled, the circuit board 100 is connected to the connecting portion 231, that is, the circuit board 100 is connected to one of the first shell 220 and the second shell 230; after wiring or maintenance of the communication module, the first shell 220 and the second shell 230 are assembled to restore the communication module; after opening the shell 200, the connecting portion 231 still fixes the circuit board 100, so that the circuit board 100 is still fixed to the first shell 220 or the second shell 230 in the exposed state, facilitating the restoration of the communication module after disassembly.

[0067] The connecting portion 231 can be provided on the first shell 220 or the second shell 230, that is, the connecting portion 231 is connected to one of the first shell 220 and the second shell 230, and in this embodiment, the connecting portion 231 is connected to the second shell 230.

[0068] Since the connecting part 231 has no connection relationship with the first subshell 220, the connection relationship between the first subshell 220 and the second subshell 230 is released, so that the first subshell 220 and the second subshell 230 can be separated, thereby opening the shell 200 to operate the exposed circuit board 100, assembling the first subshell 220 and the second subshell 230, thereby completing the assembly of the communication module, and simplifying the disassembly and assembly work of the communication module. If the circuit board 100 is connected to the first subshell 220 and the second subshell 230 respectively, it is inconvenient to disassemble or assemble the shell 200.

[0069] The connecting part 231 fixes the circuit board 100, so that the circuit board 100 is fixed to the second subshell 230, and the first subshell 220 and the second subshell 230 are disassembled, so that the circuit board 100 is exposed. At this time, the circuit board 100 connected to the second subshell 230 can be directly operated, or the circuit board 100 can be disassembled from the second subshell 230 and operated. The utility model does not make special limitation on this. The connecting part 231 fixes the circuit board 100, which can reduce the probability of the circuit board 100 falling due to the loss of support when the first subshell 220 and the second subshell 230 are separated, and reduce unnecessary loss.

[0070] In addition, the connecting part 231 has the effect of positioning, which is conducive to quickly determining the installation position of the circuit board 100, so as to reduce the probability of assembly error; the connecting part 231 fixes the circuit board 100 to the second subshell 230, which is conducive to keeping the relative position between the second subshell 230 and the circuit board 100 unchanged, so that the position of the circuit board 100 in the accommodating cavity 210 after assembly is unchanged, so as to reduce the probability of assembly error as much as possible.

[0071] Referring to Figure 3 to Figure 6 As shown in the figure, the communication module can include a first locking nut 310 and a second locking nut 320. The first locking nut 310 is sleeved outside the opening 235 to improve the reliability of the connection between the interface part 121 and the opening 235. A gasket 330 can be added inside the first locking nut 310 to increase the friction force.
