Abstract
The utility model provides a display screen's equipment with electromagnetic compatibility, this equipment include that casing, display screen, EMC glass screen cover board and metal crimping board, the concave surface has been seted up on the surface of casing, EMC glass screen covers board, display screen, metal crimping board and stacks in proper order, and fixes in this concave surface, EMC glass screen covers the board and establishes the display surface at the display screen, and the non - display surface at the display screen is established to metal crimping board. The utility model discloses an electromagnetic shield of equipment, the parts that just increase all lie in the demonstration faceplate of universal apparatus equipment, can not lead to the fact the influence to the prototype structure of equipment.
Description
Technical field
The utility model relates to electronic measurements, the compatible field of measurement and control instrument installation electromagnetical, especially relates to a kind of equipment with the band display screen of Electro Magnetic Compatibility.
Background technology
Along with the development of science and technology, the quantity of electronic system and equipment grows with each passing day, performance is also improving constantly, and forward high-frequency, ultra broadband, miniaturized, high sensitivity future development, make space electromagnetic environment complicated all the more, every have the field of electronic technology all can there is electromagnetic interference, now become the outstanding obstacle that electronic system and equipment normally work; Therefore, how in complex electromagnetic environment, guarantee electronic system and equipment interference-free, and normally to work consistently, be EMC Design Technology technical barrier in the urgent need to address, especially become more difficult in the electromagnetic Compatibility Design of the bench device having display screen.
Utility model content
The purpose of this utility model is: for prior art Problems existing, provides a kind of equipment with the band display screen of Electro Magnetic Compatibility, solves electronic system and equipment, especially with the equipment of display screen by the problem of electromagnetic interference.
The purpose of this utility model is achieved through the following technical solutions:
A kind of equipment with the band display screen of Electro Magnetic Compatibility, comprise casing and display screen, it is characterized in that, this equipment also comprises EMC glass barricade (the Chinese implication of EMC (ElectroMagneticCompatibility): Electro Magnetic Compatibility) and metal crimp fishplate bar, the surface of described casing offers concave surface, described EMC glass barricade, display screen, metal crimp fishplate bar stack successively, and be fixed in this concave surface, described EMC glass barricade is located at the display surface of display screen, and metal crimp fishplate bar is located at non-display of display screen.
As further technical scheme, described EMC glass barricade is made up of layer glass plate pressing woven wire.
As further technical scheme, the woven wire that the surrounding of described EMC glass barricade is exposed and metal crimp fishplate bar and casing close contact.
As further technical scheme, described woven wire is worked out by copper cash, and its grid is square.
As further technical scheme, the diameter of described copper cash is 0.1mm ~ 0.2mm.
As further technical scheme, the length of side of described grid is 0.8mm ~ 1.5mm.
As further technical scheme, described casing is metal shell.
Compared with prior art, the utility model has the following advantages:
1, achieve the electromagnetic shielding of equipment, and the parts increased all are positioned at the display panel of all purpose instrument equipment, can not impact the prototype structure of equipment;
2, different woven wire density can be adjusted according to the shielding demand of different frequency, realize good Electro Magnetic Compatibility;
3, structure is simple, and cost is low, effective, can extensive use.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of structural blast of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
This enforcement provides a kind of equipment with the band display screen of Electro Magnetic Compatibility, and it mainly improves at display screen place, and the Nomenclature Composition and Structure of Complexes of all the other equipment is constant.As shown in Figure 1, this equipment comprises casing, display screen 3, EMC glass barricade 2 and metal crimp fishplate bar 4.The surface of casing offers concave surface 1, and concave surface 1 is opened in casing user oriented face.EMC glass barricade 2, display screen 3, metal crimp fishplate bar 4 stack successively, and are fixed in this concave surface 1.EMC glass barricade 2 is located at the display surface of display screen 3, and metal crimp fishplate bar 4 is located at non-display of display screen 3.Due to the structural limitations effect of concave surface 1, ensure that EMC glass barricade 2 there will not be larger displacement.EMC glass barricade Main Function is conducive to sealed electrical magnetic wave.
The present embodiment EMC glass barricade 2 used is made up of layer glass plate pressing woven wire.
In order to make shield effectiveness better, the woven wire of EMC glass barricade 2 needs out exposed, and exposed woven wire out and metal crimp fishplate bar 4 and casing close contact, guarantee that formation one is for the complete confined space of electromagnetic wave, realizes the effective suppression to electromagnetic signal.
The woven wire of the present embodiment is worked out by copper cash, and its grid is square.The diameter of copper cash ensures at 0.1mm ~ 0.2mm, and the length of side of grid ensures 0.8mm ~ 1.5mm, like this can while guarantee printing opacity, different frequency electromagnetic wave of effectively decaying.The concrete diameter of copper cash and the concrete length of side of grid can adjust according to the shielding demand of different frequency.
The casing of the present embodiment is metal shell.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; it should be pointed out that all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
