Description

New-type radio-frequency test double layer screen case

Technical field：

The utility model is related to shielded box technical fields, refer in particular to New-type radio-frequency test double layer screen case.

Background technology：

Radio frequency testing technique is typically the most complicated, the maximum flow of influence in the wireless telecommunications class equipment producing line such as mobile phone, Radio frequency testing station is usually made of several parts such as test instrumentation, shielded box, test software, can usually be divided into calibration test, comprehensive again Close several classes of test, antenna measurement etc..Due to the requirement of production capacity, usual radio frequency testing technique is parallel by multiple identical testing stations Operation, shielded box are to be limited in electromagnetic capability centainly using shield variously-shaped made of conductive or permeability magnetic material In spatial dimension, the metallic object for inhibiting radiation interference.And to conducting and radiation is handled, to realize to tested channel radio The equipment that news equipment provides glitch-free test environment.

The defect of shielded box is as follows at present：2 independent shielded boxes are needed, of high cost, signal need to be from babinet outside height Frequency line connects, and interface exposure, decaying is big, and big by external noise interference, lower layer's test is directly installed on computer inside shielded box, It is small by external noise interference while saving between holding.

Utility model content：

The purpose of this utility model is in view of the deficiencies of the prior art, and to provide New-type radio-frequency test double layer screen case, Scientific structure design, finished product functional test shielded box, this scheme have following advantage：Only need 1 shielded box, save at This, signal passes through from shielded box internal partition, is separated with outside, directly solves noise cross-interference issue, reduces because of wireless noise The mistake interfered and generated is surveyed, and the fluency of producing line body is improved, and RF lines are not necessarily to, from outside access, reduce 1.5 meters of length of wires, Decay smaller, improves test yield.

To achieve the above object, the utility model adopts the following technical solution, including upper shielded box, upper cover body, lower shielding Case, upper shielded box connect upper cover body by telescopic rod, and the lower part of upper shielded box is equipped with lower shielded box, and the side of lower shielded box is equipped with Electric control box, computer heat radiation ventilation shielding mouth, filter module, signal pass in and out filter module, and computer electricity is equipped in lower shielded box Believe equipped with levels shielded box high frequency the lower face of source, computer main board, computer hard disc, wireless network card, radiator fan, upper shielded box Number interface.

The signal disengaging filter module is two or more.

There are computer switch, computer reset switch on the electric control box.

The utility model has the beneficial effect that：Upper shielded box connects upper cover body by telescopic rod, and the lower part of upper shielded box is equipped with The side of lower shielded box, lower shielded box is equipped with electric control box, computer heat radiation ventilation shielding mouth, filter module, signal disengaging filter Wave module, lower shielded box is interior to be equipped with computer power, computer main board, computer hard disc, wireless network card, radiator fan, upper shielded box Lower face is equipped with levels shielded box high-frequency signal interface, and scientific structure design saves cost, and signal is from shielded box internal partition Pass through, separated with outside, directly solve noise cross-interference issue, reduces the mistake generated because wireless noise interferes and survey, improve The fluency of producing line body, RF lines are not necessarily to access from outside, reduce 1.5 meters of length of wires, and decay smaller, improve test yield.
