Description
Technical Field
The utility model relates to an electromagnetic shield technical field, concretely relates to consolidate notebook display screen electromagnetic shield device.
Background
With the rapid development of computer technology, notebook computers are widely used in various environments such as daily life, study, entertainment, business and work of people; in some special application occasions, such as military fields and the like, besides the requirement that the notebook has excellent performance, the notebook is also required to be vibration and impact resistant and can keep normal operation in a complex electromagnetic interference environment, so that the notebook needs to be reinforced; in the notebook computer reinforcement technology, electromagnetic shielding treatment is a very important work, and is also a reinforcement content which is difficult to treat. Especially, for the electromagnetic shielding treatment of the notebook display screen part, due to the particularity of the structure composition of the display screen, the display window occupies most of the space of the display screen, so that the space in the display screen for performing the electromagnetic shielding treatment is very small, and the treatment difficulty of the part is further increased.
At present, the electromagnetic shielding treatment of the reinforced notebook display screen is mainly realized by installing shielding glass, and the shielding glass is usually in a structural form of two layers of glass and a shielding wire mesh; the common installation mode of the shielding glass is that the shielding glass is pressed tightly by a metal pressing piece, and an exposed shielding screen mesh of the shielding glass is pressed on a front cover of the display screen by the metal pressing piece; because the shielding glass exposes the shielding silk screen and all wraps up the copper foil, the copper foil is yielding to corrugate in the metal casting die compresses tightly the in-process, leads to unable and inseparable contact with the display screen protecgulum in succession, just forms the electromagnetic leakage point, influences product electromagnetic compatibility adaptability.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the prior art, the utility model aims to provide a consolidate notebook display screen electromagnetic shield device.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a consolidate notebook display screen electromagnetic shield device, includes display screen protecgulum, electrically conductive rubber pad, shielding glass and glass casting die, be equipped with the mounting groove on the display screen protecgulum for the electrically conductive rubber pad of installation is equipped with shielding screen on the shielding glass, and shielding screen area is greater than shielding glass, exposes shielding screen and lays on electrically conductive rubber pad, and the glass casting die is fixed in shielding glass on the display screen protecgulum through the screw.
Specifically, a double-sided adhesive tape is arranged between the front cover of the display screen and the shielding glass.

FIG. 1 is a schematic view of a structure of an electromagnetic shielding device for a reinforced notebook display screen;
fig. 2 is a cross-sectional view of an electromagnetic shielding device for a ruggedized notebook display screen.
In the figure: 1-front cover of display screen; 2-conductive rubber pad; 3-shielding glass; 4-glass pressing piece; 5-shielding silk screen.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, a reinforced electromagnetic shielding device for a notebook computer display screen comprises a display screen front cover 1, a conductive rubber pad 2, shielding glass 3 and a glass pressing piece 4, wherein a mounting groove is formed in the display screen front cover 1 and used for mounting the conductive rubber pad 2, a shielding screen 5 is arranged on the shielding glass 3, the area of the shielding screen 5 is larger than that of the shielding glass 3, the exposed shielding screen 5 is laid on the conductive rubber pad 2, and the shielding glass 3 is fixed on the display screen front cover 1 through a screw by the glass pressing piece 4.
A double-sided adhesive tape is arranged between the display screen front cover 1 and the shielding glass 3; the mounting groove is tightly attached to the edge of the shielding glass 3, and the depth of the mounting groove is smaller than the thickness of the conductive rubber pad 2; the exposed shielding silk screen 5 is wrapped with copper foil.
As shown in fig. 2, it can be seen from the cross-sectional view that the mounting groove of the conductive rubber pad 2 is specially designed on the front cover 1 of the display screen near the edge of the shielding glass 3, the mounting groove has a width of 3mm and a depth of 0.5 mm; the conductive rubber pad 2 is placed in the mounting groove, and is 3mm wide and 0.8mm thick. The exposed shielding screen 5 of the shielding glass 3 is flatly laid above the conductive rubber pad 2, after the fixing screw of the glass pressing piece 4 is screwed, the shielding screen 5 is tightly pressed to be in close contact with the conductive rubber pad 2 by utilizing the compressibility of the conductive rubber pad 2, and even if the shielding screen 5 is locally deformed and wrinkled, the shielding screen 5 can be ensured to be in good contact with the conductive rubber pad 2; and conductive rubber pad 2 direct mount is in the mounting groove of display screen protecgulum 1, after being installed the compression, also can guarantee conductive rubber pad 2 and the good electrically conductive contact of display screen protecgulum 1, has just so guaranteed shielding screen 5 and the conductive continuity of display screen protecgulum 1, plays good electromagnetic shield effect.
