Abstract
The invention discloses an anti-interference camera comprising a photographing module and an isolating cover. The photographing module comprises a circuit board and a camera which is arranged on the circuit board. The peripheral position, which is corresponding to the camera, on the circuit board is provided with a grounding solder pad which is used for being connected with the isolating cover. The anti-interference camera is ingenious in structural design and reasonable in structure. The isolating cover is arranged so that damage to a light-sensitive chip in the photographing module caused by static electricity in a rear end working environment can be prevented, working quality can be enhanced and the service life can be prolonged. Besides, interference generated by the photographing module on other peripheral components and parts and circuits can be effectively reduced so that photographing quality of the photographing module can be further enhanced. An electromagnetic protective film is arranged, and the isolating cover and a reinforcing plate are grounded so that anti-interference capability can be greatly enhanced.

Photographing module/module (CMOS Camera Module) is called for short CCM, is the core devices for various New Generation of Portable picture pick-up devices, has miniaturization, low-power consumption, low cost, the advantage of high image quality compared with traditional camera system.Can be widely used in the fields such as shooting mobile phone, video telephone, automobile assistant driving, security monitoring.
In recent years along with the range of application of camera module constantly expands, is also more and more higher to its requirement accordingly, comprise outside the quality requirements of high pixel, high definition etc. self, most important or will with rear end operational environment in each former device be used in conjunction with.
Electro Magnetic Compatibility EMC(Electro Magnetic Compatibility), refer to that the operation that meets the requirements of equipment or system does not produce the ability of intolerable electromagnetic interference to any equipment in its environment in its electromagnetic environment.Therefore, EMC comprises the requirement of two aspects: refer to that on the one hand the electromagnetic interference that equipment produces place environment in normal course of operation can not exceed certain limit value; Refer to that on the other hand utensil has immunity to interference to a certain degree, i.e. electromagnetic susceptibility to the electromagnetic interference existing in the environment of place.And existing module can there will be following phenomenon in application process:
1, existing module is worked in the electromagnetic environment of rear end complexity, and sensitive chip (Sensor) has the risk of being damaged by electrostatic breakdown;
2, existing module is worked in the electromagnetic environment of rear end complexity, has other periphery components and parts and circuit are produced to situation about disturbing.
Summary of the invention
The object of the invention is to, for above-mentioned deficiency, provide the anti-interference camera that a kind of structural design is ingenious, reasonable, can protect EMC.
For achieving the above object, technical scheme provided by the present invention is:
A kind of anti-interference camera, it comprises a camera module and a cage, this cage covers on described camera module, and is provided with an opening that allows the camera of this camera module expose.
