Description
Technical field
The utility model belongs to shielded box technical field, and in particular to a kind of shielded box.
Background technology
For radio communication product production firm, product can not appear on the market in time or what upper amount brought rapidly is big volume production
The loss of value and profit, and directly affect the expansion of follow-up business and the market share.Radio frequency testing technique is typically the nothings such as mobile phone
Bottleneck that is the most complicated, influenceing maximum flow, generally also producing line in line communication kind equipment producing line.Radio frequency testing station generally by
Several parts such as test instrumentation, shielded box, test software are formed, and generally can be divided into calibration test, integration test, antenna measurement etc. again
Etc. several classes.Due to the requirement of production capacity, usual radio frequency testing technique is run parallel by multiple identical testing stations.Some or some surveys
The percent of pass of trial work position is relatively low；Output reduces and may result in producing line bottleneck, production cost increases severely, and to find out its cause, can substantially divide
For：Environmental factor, the uncertain of test such as the problem of product design or material reason, test (survey problem by mistake), Radio frequency interference are asked
Topic.
Electromagnetic interference/EMI is the problem that whole electronic applications must face and overcome, typically in radio communication product
Such as：Mobile phone, wireless network card, wireless router, wireless headset, bluetooth earphone, wi-fi, wimax, data card, intercom,
RFID etc. wireless telecommunications kind equipment and wireless telecommunications generic module etc. are all by using penetrating during entering andante and surveying, survey eventually
Frequency tests shielded box to improve test environment.
It need to be explained further, shielded box is using shield variously-shaped made of conductive or permeability magnetic material, by electricity
Magnetic energy power restriction is in the range of certain space, for suppressing the metallic object of radiation interference, and to conducting and radiation is handled, with
Realize the equipment that glitch-free test environment is provided to tested wireless telecommunications system；Wherein, shielded box is widely used in down
Field is stated, is specially：1st, employing wireless communication test；2nd, EMI is tested；3rd, coupling measurement；4th, RF functional tests；5th, receive clever
Sensitivity is tested；6th, emitter radiant power is tested；7th, Bluetooth, DAB/DMB；8th, small-sized UHF equipment EMI and EMS test；
9th, the equipment such as mobile phone, bluetooth, wireless router, complete machine or chip test.
The shielded box product of existence form various kinds in the prior art；However, for existing shielded box product, in reality
During the use on border, the design of its generally existing is unreasonable, testing efficiency is low and the defects of operating with inconvenience.
Utility model content
The purpose of this utility model is to provide a kind of shielded box, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides following technical scheme：A kind of shielded box, including upper lid and lower cover,
The back edge of the upper lid and lower cover is hinged by hinge, and the upper lid is connected with the left and right side of lower cover by gas spring, institute
The inside edge for stating lower cover is provided with conducting foam, and the bottom surface of lower cover is provided with mounting base, and the medial surface of lower cover, which is provided with, inhales ripple sponge,
The bottom surface of the upper lid is provided with honeybee plate, and the honeybee plate is provided with adjusting plate, camera is provided with the adjusting plate.
Preferably, the upper front of the upper lid is provided with handle.
Preferably, the front place of suiting of the upper lid and lower cover is provided with lock uint.
Preferably, the bottom surface of the lower cover is provided with foot pad.
Technique effect of the present utility model and advantage：The shielded box, pass through the signal shielding of outer case, the sound of external shielding layer
Sound weakens, the interference barrier of outer separation layer, and the further blocking conduction of vacuum chamber, the interference signal quilt being externally entering
Weaken step by step, and the interference signal be weakened simultaneously after is also needed in experience internal shield, interior separation layer, and it is last interior
The deadening of casing, the interference signal that can be entered inside internal box is very little, improves the accuracy of test.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
