Description
Technical field
The utility model belongs to the cabinet design field, is specifically related to a kind of electromagnetic shielding cabinet.
Background technology
The utilance of current electromagnetic spectrum is intensive day by day, and the electromagnetic energy in space sharply increases.In order to make system not be subjected to the interference of external electromagnetic ripple, system need take certain measure, reduces the influence of extraneous radiation to system.Electromagnetic shielding is to use metal shield materials that electromagnetic interference source is closed, or with metal shield materials the electromagnetic susceptibility circuit is closed, and makes its internal electromagnetic field intensity be lower than permissible value, to improve the reliability and stability of system.
Summary of the invention
The purpose of this utility model is to propose a kind of novel, and is simple in structure, electromagnetic shielding cabinet with low cost.
The electromagnetic shielding cabinet that the utility model proposes, form by user's cabinet 1, user's collecting device or integrated circuit board 2 and electromagnetic shielding material 3, its structure as shown in Figure 1, wherein: user's collecting device or integrated circuit board 2 are positioned at user's cabinet 1, electromagnetic shielding material 3 is coated on outside user's collecting device or the integrated circuit board 2 or electromagnetic shielding material 3 is coated on outside user's cabinet 1, described electromagnetic shielding material 3 adopts metal material, as copper mesh.
In the utility model, described user's cabinet 1 and user's collecting device or integrated circuit board 2 can be incorporate, also can separate.
In the utility model, user's cabinet 1 and user's collecting device or integrated circuit board 2 are equipped with signaling interface, power and the signal transmission.
In the utility model, use electromagnetic shielding material 3 that user's cabinet 1 or user's collecting device or integrated circuit board 2 are wrapped up, and, provide good path over the ground, interference signal that coupling comes in is reduced the influence of instrument electromagnetic shielding material 3 ground connection.Electromagnetic shielding material 3 can be wrapped in user's cabinet 1 outside, also can be wrapped in the user's collecting device or integrated circuit board 2 outsides, decides on real needs.
Manufacture method of the present utility model is as follows:
The first step: the size of determining user's cabinet 1 or user's collecting device or integrated circuit board 2.
Second step: the size of doing user's collecting device of electromagnetic shielding measure or integrated circuit board 2 or user's cabinet 1 is as required selected the size of the electromagnetic shielding material 3 of suitable dimension.
The 3rd step: according to demand, electromagnetic shielding material 3 is wrapped in user's cabinet 1 outside, or is wrapped in the user's collecting device or integrated circuit board 2 outsides,
The utility model is simple in structure, and is with low cost, easy to use.
Description of drawings
Fig. 1 is wrapped in the structural diagrams of cabinet 1 outside for the utility model electromagnetic shielding material 3.
Fig. 2 is wrapped in the structural diagrams of collecting device or integrated circuit board 2 outsides for the utility model electromagnetic shielding material 3.
Number in the figure: 1 is user's cabinet, and 2 is user's collecting device or integrated circuit board, and 3 is electromagnetic shielding material.
