Description
Technical field
The utility model relates to a kind of low power frequency conversion device ground structure assembly.
Background technology
(Variable-frequency Drive VFD) is application of frequency conversion technology and microelectric technique to frequency converter, controls the electric control appliance of alternating current motor through changing machine operation supply frequency mode.Frequency converter mainly is made up of rectification (AC-DC), filtering, inversion (direct current becomes interchange), brake unit, driver element, detecting unit microprocessing unit etc.Reach the purpose that changes supply voltage through the frequency that changes power supply; Actual needs according to motor provides its needed supply voltage, and then reaches purpose energy-conservation, speed governing, in addition; Frequency converter also has a lot of defencive functions; Like overcurrent, overvoltage, overload protection or the like, along with improving constantly of industrial automatization, frequency converter has also obtained using very widely.Tradition low power frequency conversion device is accomplished frequency converter through hexagonal copper post and is connected with the ground connection of base plate, like Fig. 1, shown in 2, radiator 5a is installed in cabinet 1a; On radiator 5a, have screwed hole, hexagonal copper post 4a bottom has external screw thread, and is screwed in the screwed hole of radiator; Base plate 2a has installing hole, and the hexagonal copper post 4a installing hole of packing into is because the top of hexagonal copper post has screwed hole; Screw 3a is screwed in the screwed hole of hexagonal copper post by plate outer side, realize itself and base plate are fixed.The shortcoming of above-mentioned frequency converter earthing mode is: need be on base plate perforate in order to fixing hexagonal copper post, not only complex operation step, and profile is also attractive in appearance inadequately.
The utility model content
The purpose of the utility model is to solve the problems of the technologies described above, and a kind of frequency converter ground structure assembly is provided, and it can guarantee frequency converter ground connection effect, and good looking appearance, has easy accessibility, the high advantage of efficient.
For reaching this purpose, the utility model adopts following technical scheme:
A kind of frequency converter ground structure assembly comprises cabinet, base plate, and radiator is installed in the cabinet; Also comprise earth connection; Said base plate medial surface is fixed with copper plug, and the first end of said earth connection has the slot that is complementary with said copper plug, so that said copper plug can insert in the said slot; The second end of said earth connection has the pass structure that can supply screw to pass through, so that the second end of said earth connection can be through screw on said radiator.
Further, said radiator passes through screw in said cabinet.
Further, on said radiator, the first end of said earth connection and said copper plug plug the second end of said earth connection through screw, and said base plate passes through screw on said cabinet.
Preferably, said copper plug is welded on the medial surface of said base plate.
The beneficial effect of the utility model: the first end through at earth connection is provided with slot; It can be connected with the copper plug of base plate medial surface; The second end through at earth connection is provided with pass structure, and it can be through screw on radiator, easy accessibility; And avoided perforate on base plate, simple in structure, good looking appearance.

Embodiment
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and through embodiment.Shown in Fig. 3～6, in present embodiment, the described frequency converter ground structure of the utility model assembly; Comprise cabinet 1, base plate 2, the cabinet 1 inner radiator 3 of installing, the medial surface of base plate 2 is welded with copper plug 5; The first end of earth connection 4 has the slot that is complementary with copper plug 5, and promptly the earth connection first end has slotting spring terminal, and the second end of earth connection 4 has the pass structure that can supply screw to pass through; Be that the earth connection the second end has OT terminal, through the first end at earth connection slot be set, it can plug with the copper plug of base plate medial surface; The second end through at earth connection is provided with pass structure, and it can be through screw on radiator, easy accessibility; And avoided perforate on base plate, simple in structure, good looking appearance.
During assembling, at first radiator 3 is passed through screw in cabinet 1, be fixed on the radiator 3 through the second end of screw 6 again, the first end and the copper plug 5 of earth connection 4 are pegged graft each other, through screw base plate 2 is fixed on the cabinet 1 at last earth connection 4.Earth connection 4 one ends are through screw, and the other end and copper plug 5 are fixing, can accomplish dismounting quickly and easily, and production efficiency is improved; Because the binding post that meets GB is all adopted at the two ends of earth connection 4, electric property is able to assurance, and affected by environment less, can guarantee the ground connection reliability.
More than combine specific embodiment to describe the know-why of the utility model.These are described just in order to explain the principle of the utility model, and can not be interpreted as the restriction to the utility model protection range by any way.Based on the explanation here, those skilled in the art need not pay other embodiment that performing creative labour can be associated the utility model, and these modes all will fall within the protection range of the utility model.
