By adopting technique scheme, the copper sheet of the first binding post can reach the second terminals with shortest path
Son, saves the material of copper sheet and space availability ratio is higher.
Preferably, it is covered with inner groovy after described, described air outlet is arranged on inner groovy bottom land, and air outlet is circumferentially with wind
Fan installing hole.
By adopting technique scheme, the fan as flowing wind energy source need not externally protrude out in housing setting, reduces
Laying dust, the probability of damaged in collision.
Preferably, described air outlet is transversely arranged two.
By adopting technique scheme, general frequency converter shell is square, and width is longer, arranges two fans
Both take full advantage of space, wind energy can have been increased again, improve radiating effect.
Preferably, be provided with sub-dividing plate at described upper spacer assist side installation position, sub-dividing plate be higher than upper spacer upper surface and
Its frontal projected area falls in assist side installation position.
By adopting technique scheme, sub-dividing plate provides installing space for the less circuit board of some sizes, it is to avoid
Same be arranged in upper spacer surface, take upper spacer large surface area, hierarchical design makes upper chamber's space availability ratio higher.
Preferably, described upper lid is formed around lower flange, and lower flange wraps protecgulum, bonnet, left cover and right cover respectively
Top sidewall.
By adopting technique scheme, lower flange avoids and exposes than the cover plate top of other sharp sides, fall
The low injured probability of maintainer, uses and carries safer.
In sum, compared with prior art, this utility model has the advantage that
1st, compact conformation, space availability ratio is high；
2nd, radiating effect is more preferable；
3rd, maintenance is safer.
