Abstract
This utility model provides a kind of shielded box with USB interface, including casing, back plate, stretchable drawer structure, antenna structure, control box and interface module, the interface module includes N heads, choke valve, DB9 males, supply socket, air inlet, characterized in that, the interface module also includes filtering 2.0 interfaces of USB.The utility model realizes shielded box inside and outside data transfer, while making, in detection process, to reduce electromagnetic interference, the connection of shielded box and wave filter can also be realized by USB interface, further reduces the radiation interference inside outer bound pair shielded box.
Description
Technical field
This utility model is related to shield measuring technology, more particularly to a kind of shielded box with USB interface.
Background technology
At present, the wireless direction of signal transmission trend between various kinds of equipment is developed, the signal by taking mobile phone as an example, between mobile phone
Transfer mode is wireless transmission method, including wireless signal transmission reception, infrared signal transmitting reception, Bluetooth signal transmitting
The transmission of all kinds of wireless signals such as reception.In order to ensure equipment has preferably all kinds of transmission of wireless signals functions, in new product
Exploitation and the fabrication stage need to test the transmission of wireless signals function of the product.
Shielded box is the equipment for testing transmission of wireless signals, can isolate extraneous high-frequency signal interference, carry out signal transmitting
With receive test etc..Shielded box can provide the shielding test of other electronic equipments such as mobile phone.Shielded box be using conductive or
The variously-shaped shield such as shell, plate, set made by permeability magnetic material, is that electromagnetic capability is limited in the range of certain space to be used for
Suppress radiation interference, and conduction and radiation are processed to realize glitch-free test wrapper being provided to tested wireless telecommunications system
Border.
During the use of shielded box, shielded box inside and outside usually needs to carry out data transmission.General shielded box is deposited
In multiple interfaces, to realize the transmission of different types of data.But electromagnetic interference may be produced in data transmission procedure, is affected
The shield effectiveness of shielded box, and then the accuracy to testing result impacts.
Utility model content
Technical problem to be solved in the utility model is to realize the data transfer of shielded box inside and outside, while reducing
External electromagnetic interference in data transmission procedure.
To solve above-mentioned technical problem, the technical scheme adopted by this utility model is：
A kind of shielded box with USB interface, including casing, back plate, the stretchable drawer structure for placing product to be measured, day
Line structure, control box and interface module, the interface module include N heads, choke valve, DB9 males, supply socket, air inlet, more
Further include USB interface, the USB interface is filtering USB2.0 interfaces.
Further, the interface module is located at casing rear portion.
Further, one end of the USB interface is located inside shielded box, and the other end is located at outside shielded box, so as to reality
The inside and outside data cube computation of existing shielded box.Meanwhile, by the USB interface, it is possible to achieve the connection of shielded box and wave filter,
The interference signal in the external world is further shielded, the accuracy of testing result is improved.
Further, it is fixedly connected with rectangle fixing component outside the USB interface, the rectangle fixing component is provided with
Connecting hole, the hole is for being screwed with shielded box body structure.
Compared with prior art, its excellent effect is：This utility model provides a kind of shielded box with USB interface,
Shielded box inside and outside data transfer is realized, while making, in detection process, to reduce electromagnetic interference, USB can also be passed through
Interface realizes the connection of shielded box and wave filter, further reduces the radiation interference inside outer bound pair shielded box.

Above rectangular aperture, it is fixedly connected with casing with closed box open back) and interface module.
With reference to shown in Fig. 2, interface module is arranged on shielded box back, including N 111, choke valve 112, DB9 males 113,
Supply socket 114, air inlet 115, usb 1 16.
With reference to shown in Fig. 3, it is the concrete structure of usb 1 16, by the fixing component 7 of rectangle outside the USB interface 8
Surround, by fixing component 7, USB interface 8 can be fixedly mounted on shielding box body 1.More specifically, fixing component 7
Outer surface has the connecting hole no less than, can realize the fixation with shielding box body by connecting hole using screw.
With reference to shown in Fig. 4, it is the concrete structure 9 of filtering 2.0 interface of USB.
Obviously, embodiments described above is one embodiment of the present utility model, rather than the embodiment of whole.Base
Embodiment in the present invention, those of ordinary skill in the art obtained under the premise of creative work is not made it is all its
His embodiment, belongs to the scope of protection of the invention.
