Abstract
The utility model belongs to the scope of power-supply device parts, in particular to a mounting plate of a distribution box. The chamfers of four corners of a panel of the mounting plate are cut and bended into right-angle turnups, mounting plate fixed screw holes are installed on the four corners of the panel, an earthing screw hole is arranged on the right-angle turnup close to one side or four sides of the panel, a nut is welded on the back of the panel opposite to the earthing screw hole. A contact area between an earthing wire and the mounting plate 3 is increased, compaction strength is increased, contact resistance is small, simultaneously the mounting plate is convenient to mount and maintain, and equipment module earth connection is guaranteed to be good, and work is safe and reliable.
Description
Technical field
The utility model belongs to the power-supply device components range, particularly a kind of distribution box mounting panel.
Background technology
Existing mesolow power cabinet inner controller more complicated, parts are many, and parts need carry out subregion according to functional module and install; But the ground wire of each module all must be received on the mounting panel, and traditional earthing mode is one section cylindrical nut of welding on installation panel, because the cylindrical nut contact area is smaller; It is bigger earth resistance often to occur, and is the virtual connection state, influences the power supply operate as normal; Causing equipment fault, also is one of reason that causes quality problems.
The utility model content
The purpose of the utility model is to be one section cylindrical nut of welding to traditional ground connection in the prior art, because the cylindrical nut contact area is smaller, it is bigger earth resistance often to occur; And be the virtual connection state, and influence the power supply operate as normal, cause equipment fault; Also be cause quality problems deficiency, and a kind of distribution box mounting panel is provided, it is characterized in that; Four jiaos of the panels of mounting panel cut the corner cut palintrope flange that meets at right angles, and panel has the mounting panel fixing threaded hole for four jiaos; Right angle flange near one side or four limits on panel has an earthing screw hole, connects a nut at the back side of panel facing to the earthing screw eyelet welding.
The beneficial effect of the utility model is to have increased the contact area of earth connection and mounting panel and compressed intensity, makes contact resistance very little, is easy for installation and maintenance simultaneously, guarantees that EM equipment module ground connection is good, safe and reliable.
Description of drawings
Fig. 1 is the mounting plates structure sketch map.
Embodiment
The utility model provides a kind of distribution box mounting panel, explains below in conjunction with accompanying drawing.
Shown in Figure 1 is the mounting plates structure sketch map.Among the figure, four jiaos of the panel 3 of mounting panel are cut the corner cut 5 palintropes flange 4 that meets at right angles, panel has mounting panel fixing threaded hole 1 for 3 four jiaos; Right angle flange 4 near one side or four limits on panel 3 has an earthing screw hole 2, welds a nut 6 at the back side of panel 3 facing to earthing screw hole 2.Therefore increased the contact area of earth connection and mounting panel 3 and compressed intensity, made contact resistance very little, be easy for installation and maintenance simultaneously, guaranteed that apparatus module ground connection is good, safe and reliable.
Claims (1)
