Abstract
The invention discloses an anti-radiation shielding cover of a monitoring camera which uses a shielding material to obstruct or attenuate spread of electromagnetic energy between a shielded area and the outside. The shielding cover includes a shield cover body arranged between two circuit boards. The shield cover is slabby and is provided with anchor posts for fixing the shield cover in a central-symmetry manner at one side. The lower end of the shield cover body retracts inwards so that a rectangular gap is formed. The upper end and left and right ends of the shield cover body are bent to one side so that bending parts are formed. The anti-radiation shielding cover of the monitoring camera is made of an aluminum metal material and capable of shielding electromagnetic radiation well; and the specific shape of the shield cover is not only capable of ensuring an excellent electromagnetic-radiation shielding effect, but also does not interfere an original circuit structure. The shielding cover is capable of shielding effectively interferences from the electromagnetic radiation on a circuit of an image sensor of the monitoring camera so that problems of a large number of noisy points, cross grain and sloping grain of images, which are resulted from electromagnetic radiation between the circuit boards of the monitoring camera are solved to a great extent.
Description
Technical field
The invention belongs to camcorder technology field, relate to a kind of CCTV camera radiation-resistance mask.
Background technology
CCTV camera, as the main power of protection and monitor field front end product, has a wide range of applications in protection and monitor field.Especially information industry great development and society today to security protection pay attention to day by day, market promotes day by day to the requirement of CCTV camera image effect, high definition, low noise point, becomes industry development trend gradually.
Along with the development of video camera, electromagnetic interference is also more and more serious.First, in order to meet the requirement of high definition, high-resolution image sensors chip becomes to take as the leading factor.Although high-resolution image sensors chip has met the requirement of high definition, be more easily subject to the interference of electromagnetic radiation, especially ccd image sensor.Secondly, in order to meet brightness requirement at night, reduce night vision noise, the measure of taking strengthens infrared lamp supply current often, and electric current has strengthened, and electromagnetic radiation also increases thereupon.Again, camera review resolution increases, and processor working frequency increases, and high frequency radiation also comes more obvious.Finally, CCTV camera often polylith wiring board is used in combination, and has a large amount of electromagnetic radiation between wiring board, if design unreasonable or be subject to structural slab area constraints, picture signal is just easy to be subject to electromagnetic interference.As can be seen here, video camera internal electromagnetic environment is very complicated, and radiation source is various, and picture signal is vulnerable to disturb.
Summary of the invention
The present invention is exactly the problem of electromagnetic interference that is vulnerable in order to solve CCTV camera image in prior art, and a kind of CCTV camera radiation-resistance mask is provided, and to promoting camera review quality, reduces noise, has great significance.
In order to achieve the above object, the present invention adopts following technical scheme:
CCTV camera radiation-resistance mask of the present invention, utilize shielding material to intercept or decay conductively-closed region and extraneous electromagnetic energy travels, this radome comprises the radome body being arranged between two wiring boards, radome body is tabular, be provided with the anchor post of fixed mask cover one side Central Symmetry, the inside retraction in lower end of radome body forms rectangular indentation, and the upper end of radome body and left and right edges at two ends form kink to curving.
Angle in 90 ° between described kink and radome body.
The left and right sides of described radome body upper end is all provided with right-angle notch.
Described radome body adopts aluminum metal material to make.
Advantage and good effect that the present invention has are:
CCTV camera radiation-resistance mask of the present invention, aluminium metal material is made, can well electromagnetic radiation shielding, and material to obtain channel extensive, easy to process, cheap, cost performance is high; By machining, radome is made as to given shape, both can guarantee that ELECTROMAGNETIC RADIATION SHIELDING is respond well, do not interfere again original circuit structure, be convenient to install, be suitable for mass production.The effectively interference of electromagnetic radiation shielding to CCTV camera image sensor circuit of this radome, solves that the image noise that between CCTV camera wiring board, electromagnetic radiation causes is many, band problem and twill problem to a great extent.

Embodiment
Below in conjunction with the drawings and specific embodiments, CCTV camera radiation-resistance mask of the present invention is described further.Following each embodiment is not only limitation of the present invention for the present invention is described.
Fig. 1 is the structural representation of CCTV camera radiation-resistance mask of the present invention; Fig. 2 is the end view of CCTV camera radiation-resistance mask of the present invention; Fig. 3 is the stereogram of CCTV camera radiation-resistance mask of the present invention.As shown in Figure 1 to Figure 3, CCTV camera radiation-resistance mask of the present invention, utilizes shielding material to intercept or decay conductively-closed region and extraneous electromagnetic energy travels, and employing aluminum metal material is made.Aluminum metal can well electromagnetic radiation shielding, and material to obtain channel extensive, easy to process, cheap, cost performance is high.
This radome comprises the radome body 1 being arranged between two wiring boards, radome body 1 is tabular, external form is close to square, be provided with the anchor post 3 of two fixed mask covers one side Central Symmetry, anchor post position, spacing and hole size are made according to actual needs, more short better, but radome will and keep enough safe distances higher than the highest device on wiring board.Copper post and connecting line are avoided to inside locking in the lower end of radome body 1, and middle inwardly retraction forms rectangular indentation 4, avoids connecting line.The upper end of radome body and left and right edges at two ends form kink 2 to curving, for blocking more fully electromagnetic radiation.Angle in 90 ° between kink 2 and radome body 1.The development length of kink is depending on actual service condition, and the longer the better in principle, but can not touch wiring board, and will keep enough safe distance with wiring board.
The left and right sides of radome body upper end is all provided with right-angle notch 5, dodges fixed leg between plate, and right-angle notch is cut out the smaller the better, but wants can avoid fixed leg and keep enough safe distances.
Fig. 4 is the assembling design sketch of CCTV camera radiation-resistance mask of the present invention.As shown in Figure 4, radome is arranged between the first wiring board 6 and 7 two wiring boards of the second wiring board, by anchor post 3 and screw, is fixed therein on a wiring board.Fix the fixed leg 8 of two wiring boards through the position of right-angle notch 5, connecting line passes through from rectangular indentation 4.Kink 2 positions are positioned at the outside at wiring board edge, can block more fully electromagnetic radiation.
