Description
Technical field
The utility model relates to a kind of electromagnetic shielding cabinet.
Background technology
The inversion cabinet of outdoor and charging cabinet etc. need the cupboard of electromagnetic shielding, as shown in Figure 1, adopt mostly and fill screen 31 between framework 1 and door-plate 2, form an EM shielded room, play the effect that intercepts electromagnetic interference; Outdoor type electromagnetic shielding cabinet is more abominable because of environment for use, need do special water-proofing treatment, promptly fills water proof and dust proof layer 32 between framework 1 and door-plate 2, to intercept the infiltration of rainwater and dust.So, present outdoor cabinet generally all with screen 31 and water proof and dust proof layer 32 one-body molded after, affix to door-plate 2 surfaces, be filled in then in the slit between framework surface and the door-plate surface, make the electromagnetic shielding cabinet reach the purpose of waterproof and electromagnetic shielding.
Prior art is owing to one-body molded with screen 31 and water proof and dust proof layer 32, so cost is higher; Owing to both will be put together to the slit between framework surface and the door-plate surface, caused in the selection of both materials and size, have limitation; Because both are aging or the damage time is inconsistent, caused side damage the opposing party to need the wasting phenomenon of changing simultaneously.
The utility model content
The utility model provides a kind of electromagnetic shielding cabinet, has solved in the prior art electromagnetic shielding cabinet cost height, screen and water proof and dust proof layer and has had limitation, screen and water proof and dust proof layer change wasting technical problem simultaneously in the selection of material and size.
A kind of electromagnetic shielding cabinet that the utility model provides comprises: main body frame, described main body frame are provided with separated screen binding face and water proof and dust proof layer binding face; Door-plate, described door-plate is fixed on the main body frame; Screen, described shielding material is fixed on the door-plate, and the screen binding face that closely cooperates; With the water proof and dust proof layer, described water proof and dust proof layer is fixed on the door-plate, and the water proof and dust proof layer binding face that closely cooperate.
Further, described screen binding face is parallel to described door-plate.
Further, described water proof and dust proof layer binding face is parallel to described door-plate.
Further, described water proof and dust proof layer is looped around outside the screen.
Further, described screen binding face is arranged on the screen applying beam, and described screen applying beam is fixed on the main body frame.
Further, described screen applying beam is " L " type.
Further, described door-plate is provided with the door-plate buttress brace, and described screen is fixed on the door-plate buttress brace.
The utility model embodiment is provided with separated screen binding face and water proof and dust proof layer binding face, the screen and the water proof and dust proof layer that will be fixed on then on the door-plate fit tightly respectively on screen binding face and water proof and dust proof layer binding face, make screen and water proof and dust proof layer separately be arranged in the middle of main body frame and the door-plate, the contrast prior art has been lacked screen and the integrated step of water proof and dust proof layer, reduced the cost of electromagnetic shielding cabinet, because the branch of screen and water proof and dust proof layer is arranged, improved the alternative on material and size, and both do not need to change simultaneously, have saved cost.

Embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Below in conjunction with drawings and Examples the utility model is described further.
To shown in Figure 6, the utility model provides a kind of electromagnetic shielding cabinet, it is characterized in that, comprising as Fig. 2:
Door-plate 20, described door-plate 20 is fixed on the main body frame 10;
Water proof and dust proof layer 40, described water proof and dust proof layer 40 is fixed on the door-plate 20, and the water proof and dust proof layer binding face 12 that closely cooperate.
Concrete, described screen binding face 11 is parallel to described door-plate 20; Described water proof and dust proof layer binding face 12 is parallel to described door-plate 20.The advantage of doing like this is that screen 30 and water proof and dust proof layer 40 can better seal the electromagnetic shielding cabinet.
Concrete, described water proof and dust proof layer 40 is looped around outside the screen 30.Can better guarantee the effect of water proof and dust proof like this.
Concrete, described screen binding face 11 is arranged on the screen applying beam 13, described screen applying beam 13 is fixed on the main body frame 10, and described screen applying beam 13 is " L " type, and described screen applying beam 13 is fixed on the main body frame 10 by welding or Water-proof screw.Described screen applying beam 13 can strengthen the mechanical strength of main body frame 10, can also improve the effect of static release, electromagnetic shielding and water proof and dust proof.
Concrete, described door-plate 20 is provided with door-plate buttress brace 21, and described screen 30 is fixed on the door-plate buttress brace 21.Door-plate buttress brace 21 can strengthen the mechanical strength of door-plate 20, can also improve the effect of static release, electromagnetic shielding and water proof and dust proof.
The manufacture process of a kind of electromagnetic shielding cabinet of the utility model embodiment is as follows:
1, heat zinc coating plate is processed according to required sheet metal processes such as size blanking, deburring, location, bending and welding, obtained main body frame 10, screen applying beam 13, door-plate 21 and buttress brace 21;
2, by frock clamp location the screen beam 13 of fitting is welded on main body frame 10, door-plate buttress brace 21 is welded on the door-plate 20 by the frock clamp location;
3, the weld of main body frame 10 and door-plate 20 is polished, then main body frame 10 and door-plate 20 are carried out whole phosphatization processing;
