[0040] The principles and structures of the utility model will be described in detail below in combination with the drawings and examples.

[0041] At present, the technical requirements in the photovoltaic converter are higher and higher, resulting in that the volume of the photovoltaic converter is set larger and larger, which results in that it is more difficult to separate each module and then maintain it when the photovoltaic converter needs to be maintained after sale.

[0042] Based on the above problems, the utility model provides a photovoltaic converter, please see Figure 1 The photovoltaic converter provided in the utility model has the following settings:

[0043] It comprises a rectifying module 1 and an inverter module 2 arranged separately, and the rectifying module 1 and the inverter module 2 are both provided with a wiring structure 3 for connecting internal wiring and external wiring;

[0044] Meanwhile, the rectifying module 1 and the inverter module 2 both have a mainboard mounting plate 4, and the wiring structure 3 is detachably mounted on the mainboard mounting plate 4.

In this design, when the rectifying module 1 and the inverter module 2 need to be maintained, the rectifying module 1 and the inverter module 2 can be maintained respectively, and the maintenance difficulty is reduced;

[0047] Second, provided with a wiring structure 3, the wiring structure 3 is detachably mounted on the mainboard mounting plate 4, in this design, only need to remove the wiring structure 3 can separate the external wiring and internal wiring, for subsequent maintenance action, compared with the traditional design scheme, the utility model can separately produce and assemble the external wiring and internal wiring, then through the wiring structure 3 assembly can, greatly improve the production efficiency.

[0048] That is, the utility model has the following effects based on the above settings:

[0049] The utility model separates the rectifier module 1 and the inverter module 2 of photovoltaic converter and manages separately, and simultaneously divides the wiring of rectifier module 1 and inverter module 2 into internal wiring and external wiring, so that the utility model is more logical in structure layout.

[0050] Further, please refer to Figure 3 And Figure 4 The wiring structure 3 in the utility model includes a wiring male head 31 and a wiring female head 32.

[0052] The wiring female head 32 is used for connecting the external wiring of rectifier module 1 or inverter module 2.

[0053] The wiring male head 31 and the wiring female head 32 are detachably connected.

[0054] Based on the above design, the utility model can produce and assemble the internal wiring and external wiring separately.

[0055] From the above settings, compared with the scheme that the external wiring and internal wiring are directly connected in the prior art, the utility model is more convenient to realize the connection of internal wiring and external wiring, and when producing external wiring, the connection relationship with internal wiring does not need to be considered, and the external wiring can be produced separately, then connected with the wiring female head 32, which greatly improves the production efficiency.

[0056] Please refer to Figure 3 And Figure 4The utility model discloses a plurality of plug-in columns 311 are provided to the wire male head 31, and the wire female head 32 has a plurality of plug-in interfaces 321 matched with the plug-in column 311.

[0057] When the wire male head 31 and the wire female head 32 are plugged, the plug-in column 311 is inserted into the plug-in interface 321.

[0058] The plug-in column 311 and the plug-in interface 321 are used for connecting the wire male head 31 and the wire female head 32, and when the internal wiring is assembled with the wire male head 31, the internal wiring can be connected to the plug-in column 311, and when the external wiring is assembled with the wire female head 32, the external wiring can be connected to the plug-in interface 321, so that the electrical connection between the internal wiring and the external wiring can be realized by the butt joint of the plug-in column 311 and the plug-in interface 321.
