Description

200412695 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a flexible circuit board connector (FPC connector), especially a flexible circuit board connector capable of preventing electromagnetic wave interference (EMI) [prior art]

Due to the continuous increase of the "working frequency" of current electronic products, the electromagnetic wave radiation caused by electric power during the operation of electronic products is becoming more and more serious. As a result, electronic products are often affected by electromagnetic waves of other electronic products = disturbance (jlectro-magnetic lnterference) , EMI), and there are situations where st * 正 # is used or there is instability in use. Therefore, this kind of interference caused by the leakage of electromagnetic waves from electric products has become a problem of environmental pollution in the new century. In addition, in order to solve this problem caused by electromagnetic wave interference, countries around the world have also begun to target various problems. Electronic products formulate strict electromagnetic wave interference control standards, especially the electromagnetic compatibility between electronic products < ^ lectr0-MagneticcompatismHty (EMC), more strict requirements and attention.

First, to achieve the most direct way to prevent electromagnetic interference, electronic products use a metal shell with electromagnetic shielding effect. In addition to completely blocking the circuit components of the electronic product from the outside, the ground of the metal shell is used. Guide and evacuate the electromagnetic wave wheel to the ground to prevent electronic products from being interfered by magnetic waves and maintain the stability of their normal use. However, the existing connector products, especially the flexible circuit board connection (FPC CONNECTOR), are almost not provided with electromagnetic shielding effects.
