Description

  The present invention relates to a shield housing and an electronic device.

  In general, an electronic device having an electronic circuit or the like is provided with countermeasures against static electricity or electromagnetic noise in order to improve the reliability of the device. For example, electronic devices and the like that require high operational reliability are subjected to ESD (Electro-Static Discharge) countermeasures and VCCI (Voluntary Control Council for Information Technology Equipment) countermeasures. Specifically, it is common to protect the controller and board from static electricity and electromagnetic noise by covering and grounding the controller and board of the device with a shield housing that blocks static electricity and electromagnetic noise.

  For example, in Patent Document 1, the periphery of an external IF (Inter Face) connector that is disposed on a substrate in the frame and exposed to the outside of the frame is covered with a panel, and the external IF connector is grounded through the panel and the frame. Technology is disclosed. In this way, by taking measures against the external IF connector that is likely to leak and leak static electricity and electromagnetic noise, the influence of static electricity and electromagnetic noise on the controller and board of the device is reduced.
