An inverter circuit board fixing structure

Abstract

The invention provides an inverter circuit board fixing structure which comprises a machine case shell and a PCB. Multiple limiting protrusions are arranged in the machine case shell, multiple limiting clamping slots are formed in the PCB, the positions of the limiting protrusions are in one-to-one correspondence with those of the limiting clamping slots, and the limiting protrusions are connected in the limiting clamping slots in a clamped mode. The inverter circuit board fixing structure can rapidly conduct positioning on the PCB and can effectively prevent the PCB from moving back and forth in the assembling process, therefore, the assembling speed can be effectively increased, and the production efficiency and the product quality can be effectively improved; meanwhile, by means of the inverter circuit board fixing structure, an inner cavity of the machine case shell only needs to be made to be in the same size as that of the PCB, so that not only can the appearance of an inverter be more attractive, but also the size of the machine case shell of the inverter can be effectively reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to a photovoltaic inverter, in particular to a fixing structure for an inverter circuit board. Background technique [0002] With the increasing shortage of energy and the aggravation of environmental pollution, clean energy and renewable energy have become the key areas of development in countries around the world. Among them, photovoltaic power generation technology has attracted more and more attention because of its green, environmental protection, and renewable advantages. and welcome. In photovoltaic power generation technology, the inverter used to convert DC power generated by photovoltaic modules into AC power is a key component of the entire photovoltaic power generation technology. [0003] The inverter mainly includes two parts: the inverter casing and the PCB circuit board. The inverter circuit is arranged on the PCB circuit board, and the PCB circuit board is fixed on the inverter casing. In the prior art, the PCB ...

Problems solved by technology

However, in the actual assembly process, it is difficult to make the through holes on the PCB circuit board and the screw holes on the support column correspond up and down in one step, and the position of the PCB circuit board needs to be constantly moved during assembly.

This brings two defects: 1) The assembly speed is slow, and the position of the PCB circuit board must be constantly moved for each assembly, so that the through holes on the PCB circuit board correspond to the positions of the screw holes on the support column, and the assembly time is long. Low production efficiency; 2) In order to facilitate the movement of the PCB circuit board, it is usually necessary to set a large gap between the inner wall of the inverter housing and the PCB circuit board, which will increase the size of the inverter housing, which will make the Increased production costs
