Abstract
The invention provides a high-strength unit drawer with a light structure. The unit drawer is structurally characterized in that a movable plug-in connector connected with a vertical bus and a movable plug-in connector plugged with a turn-out static plug-in connector are arranged on a rear plate of the drawer; a double-thread screw linear transmission mechanism is arranged on a bottom plate of the drawer; the periphery of a panel of the drawer is pressed and folded to form double folded edges of the panel; the folded periphery serves as circular edges of the double folded edges; two sides of left and right side plates of the drawer form left and right side plate single folded edge of the drawer; and the edges of the single folded sides also serve as the circular edges of the double folded edges. The high-strength unit drawer with the light structure, provided by the invention, has three advantages that the structural form of the drawer is unified, so that the drawer is suitable to be used as the unit drawer of the existing cupboards with different models, and the industrial production can be realized; by using the double folding process, a material is thinned and strengthened, the economization of the material and the reduction of the production cost are realized, the appearance quality of parts is improved, and a bezel edge of a notch is eliminated when the drawer is operated, thereby preventing the phenomenon that the hands of an operator are frequently scratched; and the generalization degree of the drawer is improved, and the plug-in and the plug-out of the high-current movable and static plug-in connectors are facilitated.
Description
Technical field
The present invention is that the unit drawer (hereinafter to be referred as drawer) of high strength light structure is as MCC(motor control center in the low-voltage drawer type power distributing cabinet) circuit units of cabinet is used.The bearing structure parts of each independent loop cellular installation electric components in the MCC cabinet, these parts are connected with vertical bus in the MCC cabinet, obtain incoming power, be connected to finish again the distribution purpose of feed or control unit by outgoing line plug and external outlet cable.The Design and manufacture field that belongs to the low-voltage distribution cabinet main structural components.
Background technology
The drawer parts that use in the MCC cabinet of low-voltage distribution cabinet at present, its constitutional detail all are to adopt the thick cold-rolled steel sheet of 2.0 ~ 2.5mm to be assembled through punching press, bending; The operating mechanism that extract out three positions of drawer (connect, test, isolate) is taken their own roads according to product type, and the cam Linear transmission is arranged, and the lever plug is arranged, and the transmission of worm and gear multi-turn is arranged, identical or each defectiveness of its function.The structure disunity has brought inconvenience to generalization production; The inlet wire of drawer and vertical bus patch also have multiple, commonly used a kind of with to introduce cabinet type (MNS) identical, with patching of inserted sheet tape cable wire.This mode is applicable to little current capacity and uses, as being used for feeder line than high current capacity, because the excessive (Two bors d's oeuveres 50 ~ 70mm of connection cable diameter
2), and drawer can be regional limited for what peg graft, the bending radius of cable is too little, thereby makes the inserted sheet deflection.Inserted sheet and vertical bus patch the part discontinuity, and resistance increases, and temperature rise improves, even clinkering.Use the cable link cost also high.And another kind of commonly used be to use the fixed connection of sound plug-in unit, its reed that patches part is according to the size of current closed assembly.Because area of dissipation can not effectively utilize the impact with kelvin effect, reduced the current capacity of plug portion under the equal sectional area.In view of the defective that above-mentioned prior art exists, developing one can generalization production, can overcome above-mentioned technological deficiency again, and the drawer that can reduce production costs needs.
Summary of the invention
The object of the invention is to the defective for above-mentioned existence, propose one and can save material, can guarantee again the structural strength of drawer, and can be used in the novel laborsaving operating mechanism of the sound plug-in unit that is fixedly connected with and three positions of present use the unit drawer of the high strength light structure on the drawer.
Technical solution of the present invention; Its structure comprises drawer panel, drawer left side plate, drawer-bottom board, drawer backboard, the moving plug-in unit that wherein is connected with vertical bus and with produce moving plugin card installation that quiet plug-in unit plugs on drawer backboard, the double threaded screw linear drive is installed on the drawer-bottom board, the flanging folding is panel two pass flanging around the drawer panel, become the arc-shaped edges behind the double-fold around behind the flanging, the both sides of drawer left side plate are drawer left side plate single track flanging, and the edge of drawer left side plate single track flanging also becomes the arc-shaped edges behind the double-fold.
Advantage of the present invention: 1) unified the version of drawer, the unit drawer that makes drawer be applicable to present various model (MNS GCS GCK etc.) cabinet adopts.Thereby reach the purpose of standardised generic production.2) because the drawer major part; Drawer panel and left side plate have adopted double-fold technique, and material thickness attenuate and strength increase have been saved raw-material practicality, have reduced production cost.3) adopt the double threaded screw linear drive, unified mode of operation, thereby the generalization degree of drawer is improved, and the use of double threaded screw linear drive, made things convenient for the plug of large electric current sound plug-in unit.4) because after having adopted double-fold technique, the presentation quality of part is improved, and has eliminated drawer otch basil limit in use.The phenomenon of in drawer assembling and use procedure, having avoided operating personnel's hand often to be scratched.
