Description
Technical field
The present invention relates to a kind of shielding camera bellows.
Background technology
With the fast development of electronic technology, electromagnetic environment is increasingly sophisticated, and military and civilian field all uses equipment
Electromagnetic environment proposes tightened up requirement.When Semi-Physical Simulation Test System is tested, the leakage of installation electromagnetical signal makes
It is more complicated to test electromagnetic environment, test process and test result confidence level can not only be impacted in this way, is also participated in the experiment
The health of personnel brings certain harm.Therefore, experiment carries out usually in shielded anechoic chamber, and antenna, radar are done in darkroom
Equal radio communication products and electronic product test can improve the measuring accuracy and efficiency of equipment under test against noise jamming.When
When external cable is connect with dark indoor electronic equipment, it is necessary to open up on the shielding layer through-hole for cable across the through-hole into
Enter inside darkroom, to prevent electromagnetic wave from being propagated by the through-hole, it is necessary to shield camera bellows and a large amount of cables are concentrated and run through shielded layer
Place is effectively shielded, and shielding camera bellows is the device that the relatively good cable of current shielding properties runs through shielded layer.
Shielding camera bellows common at present has orthogonal box-type and red copper particle pressure to fill out formula etc., after completing cable connection, in case
Absorbing material is filled in body, to reach shielding purpose.But such shielding often has gap or the cable that comes in and goes out is non-orthogonal
Electromagnetic-wave leakage is caused, the performance requirement of high performance shielded anechoic chamber is unfavorable for.
Invention content
The technical problem to be solved in the present invention is to provide a kind of raising cables to pass through the shield effectiveness at the shielded layer of darkroom
Shield camera bellows.
In order to solve the above technical problems, the present invention uses following technical proposals:
The bottom of a kind of shielding camera bellows, including the babinet that is made of an electrically conducting material, the babinet tilts downwards extension simultaneously
In bottom, lowest position is provided with leakage hole, and the leakage hole is equipped with the leakage lid for closing the leakage hole, described
The side wall for being located at the outlet notch into notches for wire and outlet notch is offered in the two lateral walls of babinet respectively close to center
Pan Xiankou is additionally provided at position, the Pan Xiankou is equipped with the disk line lid for closing the Pan Xiankou.Cable is by into notches for wire
It into babinet, at least spirals in babinet and is drawn after a week by outlet notch, it can be ensured that the cable that comes in and goes out is orthogonal.After cable cloth is complete,
Red copper particle is poured into babinet, until filling up, can ensure that red copper particle by babinet because the bottom of box tilts down extension
Tight is filled up, to achieve the purpose that electromagnetic wave No leakage.
Preferably, the bottom of the babinet is the semicircular in shape extended downwardly, and is equipped in semicircular bottom centre
Leakage hole.
Preferably, the bottom of the babinet is the conical by its shape extended downwardly, and leakage hole is equipped at the vertex of a cone of bottom.
Preferably, described into being both provided with the conduit that oblique upper extends outward on notches for wire and outlet notch.
Preferably, the outside of the babinet is equipped with the connecting plate for being connect with shielded layer.
Beneficial effects of the present invention are as follows:
A large amount of cables by entering shielded cable babinet into notches for wire, at least to spiral in shielded cable babinet after a week by
Outlet notch is drawn, it can be ensured that the cable that comes in and goes out is orthogonal.
After cable cloth is complete, red copper particle is poured into shielded cable babinet, until filling up, it can be ensured that shielded cable case
Tight in body achievees the purpose that electromagnetic wave No leakage.
The shielding dark box device of the present invention is a kind of good device of shielding properties, can be wide in shielded anechoic chamber or shield
General application.
