Abstract
The utility model discloses a three-large-piece type machine case of an electronic apparatus, which is used as a box body of a back insertion type man-machine interface device of a printed circuit board. The machine case is mainly composed of a press casting aluminum member, an extrusion aluminum section member and a rear cover plate. The machine case overcomes the defect that the existing congener machine case has complicated structure, multiple components, complicated technology and high cost, and improves the overhauling maintainability of the apparatus.
Description
Technical field
The utility model relates to a kind of cabinet, and it is used for inserting as the printed circuit backboard case shell of formula human-computer interface device.
Background technology
At present, some technical field---especially communications industry and power industry need be used the human-computer interface device that a kind of printed circuit board (PCB) inserts from the rear, and the front panel of this device is provided with display unit, is plugged with printed circuit board (PCB) in the case shell.In the prior art, the cabinet of this type of device is the loose mail modular construction, it is formed member and comprises: protective cover, front panel, installation frame, forward flange, liquid crystal installation component, radome, middle cross beam, bus board mounting rail, spliced casing, rear cross beam, rear flange, nut strip, subpanel etc., and by each above-mentioned member is assembled together the cabinet that forms human-computer interface device successively.But, because this cabinet is a modular construction, its number of forming member is a lot, so be difficult to the accumulation of each member foozle of control, cause cost height, the rate of finished products of product low, in addition, complex structure, the technological process of production of this cabinet are loaded down with trivial details, and the repair and maintenance in application process is also very poor.
The utility model content
The purpose of this utility model is to overcome problems of the prior art, a kind of three-major-items formula electronic installation cabinet is provided, it is used as the case shell that the printed circuit backboard is inserted the formula human-computer interface device, this cabinet mainly is made up of a die casting aluminium matter member, an extruded aluminium section member and a back shroud, it has overcome existing uniform machines box structure complexity, component number is many, technology is loaded down with trivial details, cost is high deficiency, and can improve the repair and maintenance of device.
According to an aspect of the present utility model, a kind of cabinet that the printed circuit backboard is inserted the formula human-computer interface device that is used for is provided, this cabinet is a three-major-items formula structure, it comprises:
One die casting aluminium matter member, it is positioned at the front portion of described cabinet;
One extruded aluminium profile part, it has surrounded the casing of described cabinet, and the two ends of this profile piece are openings, and described die casting aluminium matter member is connected with this profile piece by screw, has sealed the opening of one end thus;
One split type back shroud, it can be connected on the described profile piece, to seal the opening of its other end.
According on the other hand of the present utility model, described cabinet also comprises a protective cover, has a transparent part on this protective cover.
According to another aspect of the present utility model, installation frame, forward flange, liquid crystal installation component, radome, middle cross beam, bus board mounting rail, preceding nut strip have been formed on the described die casting aluminium matter member; Box plate, rear cross beam, rear flange, back nut bar have been formed on the described extruded aluminium profile part.
Because electronic installation cabinet of the present utility model has adopted overall construction design, so have simple in structure, advantages such as economic effect is obvious, production technology is simple, reliable product quality.
From the detailed description of hereinafter doing, can more clearly understand above-mentioned content of the utility model and other feature and advantage with reference to accompanying drawing.
Description of drawings
Below with reference to accompanying drawings preferred implementation of the present utility model is described in detail, in the accompanying drawings:
Fig. 1 is the overall axonometric drawing according to the human-computer interface device cabinet of the utility model one execution mode;
Fig. 2 is the axonometric drawing of die casting aluminium matter member in the cabinet shown in Figure 1; And
Fig. 3 is the axonometric drawing of extruded aluminium profile part in the cabinet shown in Figure 1.
Embodiment
Below with reference to accompanying drawings basic principle of the present utility model and illustrative embodiments are explained in detail.
As shown in the figure, comprise protective cover 1, transparent part, aluminum die-casting spare 2, extruded aluminium section spare 3, back shroud 4 and assembling pin 5 according to cabinet of the present utility model, wherein, protective cover 1 couples together with aluminum die-casting spare 2 usefulness pins 5, aluminum die-casting spare 2 then couples together with four M4 screws with extruded aluminium section spare 3, and extruded aluminium section spare 3 also is connected with screw with back shroud 4.
Wherein, compare with loose mail assembly type cabinet of the prior art, die casting aluminium matter member 2 Jian frame up frame, forward flange, liquid crystal installation component, radome, middle cross beam, bus board mounting rail, preceding nut strip in one, and extruded aluminium profile part 3 integrates spliced box plate, rear cross beam, rear flange, back nut bar, and die casting aluminium matter member 2 and aluminium section spare 3 are only assembled the problem that has promptly solved sealing, shielding with four M4 screws, and split type back shroud 4 has solved the defective that packaging technology is loaded down with trivial details, service work is complicated.
The utility model has solved demands such as shielding, Liquid crystal module installation, bus board installation, application apparatus installation by adopting easy die casting and profile piece, also guaranteed the necessary precision of cabinet simultaneously, and simplified packaging technology, both satisfied and overhauled problem easily in the practical application, had good sealing, function of shielding again.
For present embodiment, compare with cabinet of the prior art, processing technology has reduced 85%, and packaging technology has reduced 90%, the standard degree of product has improved 80%, and dustproof, airtight, anti-interference, the anti-electromagnetism numerical value of device all meets the demand of electronic installation.This cabinet is an overall structure, and its technology is more suitable for large-scale production.In addition, as adopting Dacroment technology, then can make device have the surface of hommization.
Although above embodiment of the present utility model is described, but this only is exemplary, those skilled in the art can figure out: in claims institute restricted portion, multiple other execution mode can also be arranged, and all based on the execution mode of the utility model design philosophy all in scope of the present utility model.
