Abstract
The invention discloses an earthing structure assembly of a transducer. The assembly comprises a chassis and a baseboard; a radiator is installed in the chassis; the assembly further comprises an earthing wire; a copper insert is fixed at the inner side of the baseboard; the first end part of the earthing wire is provided with a slot which matches with the copper insert so that the copper insert can be inserted into the slot; and the second end part of the earthing wire is provided with a hole-like structure through which bolts can pass so that the second end part of the earthing wire can be fixed on the radiator through bolts. Provided with the slot, the first end part of the earthing wire can be plugged and spliced with the copper insert at the inner side of the baseboard, and provided with the hole-like structure, the second end part of the earthing wire can be fixed on the radiator through bolts, so the earthing wire is convenient to mount and dismount. Furthermore, perforation on the baseboard is avoided, so the earthing structure assembly is simple in structure and attractive in appearance.
Description
Technical field
The present invention 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.
Summary of the invention
The objective of the invention is to solve the problems of the technologies described above, a kind of frequency converter ground structure assembly is provided, 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 present invention 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.
Beneficial effect of the present invention: 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 technical scheme of the present invention below in conjunction with accompanying drawing and through embodiment.Shown in Fig. 3～6, in present embodiment, frequency converter ground structure assembly of the present invention; 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 know-why of the present invention.These are described just in order to explain principle of the present invention, and can not be interpreted as the restriction to protection range of the present invention by any way.Based on the explanation here, those skilled in the art need not pay performing creative labour can associate other embodiment of the present invention, and these modes all will fall within protection scope of the present invention.
