Preferably, described spacing preiection, support column are structure as a whole with described casing.
Preferably, the periphery described PCB connecting through hole is provided with annular grounding copper dish, described annular grounding copper dish
Contact with described support column.
As it has been described above, inverter circuit board fixing structure of the present utility model has the advantages that this inverter electricity
Road board fixing structure arranges spacing preiection in casing, and arranges and spacing preiection position pair in PCB simultaneously
The spacing draw-in groove answered, so when being fixed PCB, only need to be stuck in spacing draw-in groove one to one by spacing preiection
In just spacing draw-in groove can be fixed, the most not only quickly PCB can be positioned, and can effectively prevent
It moves back and forth in an assembling process, therefore can be effectively improved the speed of assembling, is effectively improved production efficiency and product quality；With
This structure of Shi Caiyong, that the inner chamber of casing only need to do and PCB inner chamber is onesize, the most not only may be used
The outward appearance making inverter is more beautiful, and can effectively reduce the volume of inverter casing, saves production cost.

Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model being described below, those skilled in the art can be by this
Content disclosed by description understands other advantages of the present utility model and effect easily.
Refer to Fig. 1 to Fig. 4.It should be clear that structure depicted in this specification institute accompanying drawings, ratio, size etc., the most only in order to
Coordinate the content disclosed in description, understand for those skilled in the art and read, being not limited to this utility model
Enforceable qualifications, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or size
Adjust, under not affecting effect that this utility model can be generated by and the purpose that can reach, all should still fall at this utility model
In the range of disclosed technology contents obtains and can contain.Meanwhile, in this specification cited as " on ", D score, " left ",
