Abstract
The invention discloses a test cabinet shielding structure. The test cabinet shielding structure comprises a top cover of a test cabinet and a base. The top cover is internally provided with a shielding box, the upper end of the side surface of the shielding box extends outwards to form a connecting portion, and the connecting portion is connected with the top cover; and conductive silicon rubber is arranged at the connecting portion between the top cover and the base. According to the invention, the sealing effect of the cabinet can be ensured, electromagnetic interference is also effectively avoided, the test precision is guaranteed, and later maintenance is facilitated.
Description
Technical field
The present invention relates to a kind of test cabinet shielding construction.
Background technology
In electronics manufacturing enterprise, can relate to the production of the electronic products such as terminal, connector, connecting line, the said goods needs to test it after producing.The cabinet of tester comprises upper cover and base, and circuit module and some components and parts are all placed in chassis cover, and during real work, above-mentioned electrical part can produce electromagnetic field of high frequency in upper cover, can produce interference like this, affect measuring accuracy to test result.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide the test cabinet shielding construction of a kind of good airproof performance, anti-electromagnetic interference (EMI).
For achieving the above object, technical scheme of the present invention is:
A kind of test cabinet shielding construction, comprise upper cover and the base of test cabinet, be provided with a shielding box in described upper cover, the upper end, side of this shielding box extends outward a junction, and described connecting portion is connected with upper cover; Described upper cover and base junction are provided with a conductive silicon rubber.
The invention provides a kind of test cabinet shielding construction newly, not only can ensure the sealing effectiveness of cabinet, and effectively avoid electromagnetic interference (EMI), ensure that measuring accuracy, be beneficial to later maintenance.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below.
Fig. 1 is a kind of structural representation testing cabinet shielding construction disclosed in the embodiment of the present invention.
1, upper cover 2, base 3, shielding box 4, connecting portion 5, conductive silicon rubber
Embodiment
Below in conjunction with accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described.
As shown in Figure 1, a kind of test cabinet shielding construction, comprise upper cover 1 and the base 2 of test cabinet, be provided with a shielding box 3 in described upper cover 1, the upper end, side of this shielding box 3 extends outward a junction 4, and described connecting portion 4 is connected with upper cover 1; Described upper cover 1 is provided with a conductive silicon rubber 5 with base 2 junction.
Tester cabinet is made up of upper cover 1 and base 2 two parts, if only top lid 1 directly contacts with base 2, the contact of seam crossing is difficult to continuously, and shield effectiveness is greatly affected, and for ensureing the continuous sealing of seam, can install the conductive silicon rubber 5 of band electrically conductive particles additional.The structure of upper cover 1, base 2 seam crossing adopts form shown in Fig. 1, so not only can improve shield effectiveness, can also provide reliable environmental sealing.Simultaneously in order to avoid upper cover 1, the two-part mutual interference of base 2, cover with the circuit module, components and parts, parts etc. of a shielding box 3 by whole upper cover 1 li during design, make maintenance more convenient like this.Shielding box 3 utilizes conduction or permeability magnetic material to make, electromagnetic capability is limited within the scope of certain space, for suppressing the metallic object of radiation interference, and conduction and radiation are processed, to realize the equipment providing glitch-free test environment to tested wireless telecommunications system.
The invention provides a kind of test cabinet shielding construction newly, not only can ensure the sealing effectiveness of cabinet, and effectively avoid electromagnetic interference (EMI), ensure that measuring accuracy, be beneficial to later maintenance.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all amendments of making within spirit of the present invention and converting on an equal basis, all should drop within protection scope of the present invention.
