Abstract
The utility model discloses a kind of frequency converter device chassis ground, comprise frequency converter and radiator; Described frequency converter comprises body, frequency converter plastic cement and frequency converter base plate; Described frequency converter plastic cement is provided with mounting hole site; Earthing position on described frequency converter base plate is punctured in mounting hole site from frequency converter plastic cement; Described frequency converter base plate and radiator are connected by screw; Described frequency converter is fixing on a metal plate by mounting screw.Frequency converter of the present utility model device chassis ground, adopts and changes the version of base plate, and by the mounting screw of band bullet pad directly by base plate with install iron plate and couple together and make, it is high to install frequency converter efficiency, saves brokenly the operation of painting bare metal face; Screw is directly pressed on base plate, and pressure is larger; The bullet pad of screw and thread contact, ensured that ground connection not easily loosens; Reduce failure incidence, do not need bare metal face, by the conduction that is threaded, slowed down the speed of getting rusty.
Description
Technical field
The utility model belongs to frequency converter field, is specifically related to a kind of frequency converter device chassis ground.
Background technology
In frequency converter industry, Small-power Inverter is arranged on iron plate wall and uses, and the mode of ground connection is that frequency converter base plate contacts with iron plate and realizes.Owing to preventing getting rusty, surface spraying is generally all wanted in the iron plate surface of installing frequency converter wall, in order to be grounded, the iron plate surface of spray insulation must be carried out brokenly paint process, expose the metal covering of a small size, this will bring following problem to frequency converter ground connection: earthing mode resistance is large, because exposed metal covering is lower than the face of spraying paint of surrounding, loose contact, impact conduction; Earthing mode likely lost efficacy, and the exposed metal covering time has been grown and likely can get rusty, particularly at moist sour environment; Therefore, for solving the problem, urgently research and develop a new frequency converter device chassis ground.
Summary of the invention
(1) technical problem that will solve
For solving the problem, the utility model proposes a kind of reliability high, reduce failure incidence and simple frequency converter device be chassis ground installed.
(2) technical scheme
Frequency converter of the present utility model device chassis ground, comprises frequency converter and radiator; Described frequency converter comprises body, frequency converter plastic cement and frequency converter base plate; Described frequency converter plastic cement is provided with mounting hole site; Earthing position on described frequency converter base plate is punctured in mounting hole site from frequency converter plastic cement; Described frequency converter base plate and radiator are connected by screw; Described frequency converter is fixing on a metal plate by mounting screw.
Further, described mounting screw is pressed on frequency converter base plate through mounting hole site, and screw is directly pressed on frequency converter base plate, and earth resistance is reduced, and pressure is larger.
Further, described frequency converter base plate is connected by the screwed hole of screw and metallic plate or drive screw with realizing, and such connection has ensured that ground connection not easily loosens, do not need bare metal face, and by the conduction that is threaded, reduce failure incidence, slowed down the speed of getting rusty.
Again further, it is fixing that described mounting screw coordinates bullet pad to use, fixing more firm.
Preferably, described metallic plate is for installing iron plate.
(3) beneficial effect
The utility model compared with prior art, it has following beneficial effect: frequency converter of the present utility model device chassis ground, adopt the version changing base plate, directly base plate and installation iron plate are coupled together by the mounting screw of band bullet pad and make, frequency converter efficiency must be installed high, save brokenly the operation in paint bare metal face; Earth resistance is little, and screw is directly pressed on base plate, and pressure is larger; Ground connection is more reliable, and the bullet pad of screw and thread contact, ensured that ground connection not easily loosens; Reduce failure incidence, do not need bare metal face, by the conduction that is threaded, slowed down the speed of getting rusty.

Fig. 2 is frequency converter base plate of the present utility model and plastic cement main body front schematic view;
Fig. 3 is that frequency converter base plate of the present utility model and plastic cement body floor intert connection diagram.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, frequency converter of the present utility model device chassis ground, comprises frequency converter 1 and radiator 2; Described frequency converter 1 comprises body 3, frequency converter plastic cement 4 and frequency converter base plate 5; Described frequency converter plastic cement 4 is provided with mounting hole site 6; Earthing position on described frequency converter base plate 5 is punctured in mounting hole site 6 from frequency converter plastic cement 4; Described frequency converter base plate 5 is connected by screw (not shown) with radiator 2; Described frequency converter 1 is fixed on metallic plate 8 by mounting screw 7.
Described mounting screw 7 is pressed on frequency converter base plate 5 through mounting hole site 6, and screw (not shown) is directly pressed on frequency converter base plate 5, and earth resistance is reduced, and pressure is larger; Described frequency converter base plate 5 is connected by the screwed hole of screw (not shown) and metallic plate 8 or drive screw with realizing, such connection has ensured that ground connection not easily loosens, do not need bare metal face, and by the conduction that is threaded, reduce failure incidence, slowed down the speed of getting rusty; It is fixing that described mounting screw 7 coordinates bullet pad (not shown) to use, fixing more firm; Described metallic plate 8 is for installing iron plate.
Frequency converter of the present utility model principle of device chassis ground: adopt and change the version of base plate, by the mounting screw of band bullet pad directly by base plate with install iron plate and couple together and make, it is high to install frequency converter efficiency, saves brokenly the operation of painting bare metal face; Earth resistance is little, and screw is directly pressed on base plate, and pressure is larger; Ground connection is more reliable, and the bullet pad of screw and thread contact, ensured that ground connection not easily loosens; Reduce failure incidence, do not need bare metal face, by the conduction that is threaded, slowed down the speed of getting rusty.
Embodiment recited above is only be described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection range of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
