  • Publication number: 20150055304
    Abstract: An electronic device including a main chassis, an electronic module and an electromagnetic interference shielding structure is provided. The electronic module is disposed in the main chassis. The electromagnetic interference shielding structure includes a conductive plate and a plurality of conductive elastic pieces. The conductive plate is assembled to the main chassis. The conductive elastic pieces are connected to the conductive plate and arranged along a first direction. Each of the conductive elastic pieces extends along a second direction perpendicular to the first direction. Each of the conductive elastic pieces has an arc contacting surface, and the arc contacting surface of at least one of the conductive elastic pieces contacts the electronic module. An electromagnetic wave emitted from the electronic module passes through the corresponding conductive elastic piece and the conductive plate in sequence to be transmitted to the main chassis.

  • Patent number: 8279337
    Abstract: A casing of a webcam improves the hand feel of turning a lens ring. A base of the casing includes a sheath hole having a first connection portion, a first ring-shaped flange formed around an upper side of the lens ring, a second connection portion formed between upper and lower sides of the lens ring, and a second ring-shaped flange formed around the lens ring and abutted against an upper side of the sheath hole and a lower side of the first connection portion, and the first and second ring-shaped flanges of the lens ring are separated from the sheath hole by an interval. A flexible ring is clamped between the first and second connection portions and disposed between the first and second ring-shaped flanges, such that the casing can have a greater manufacturing tolerance to reduce manufacturing costs, and provide a better hand feel of turning the lens ring.

  • Publication number: 20110284258
    Abstract: A casing of an electronic device includes an opening securely covered and remained unused to prevent the opening from being exposed. The casing includes a casing body and a cover plate, and the casing body has an opening and a thermoplastic pillar installed vertically inside the casing body. The thermoplastic pillar is proximate to the opening and includes a fixed portion formed at an end of the thermoplastic pillar. The cover plate is covered onto the casing body to cover the opening and has a positioning hole for passing the thermoplastic pillar, and the positioning hole is smaller than the fixed portion, such that the opening of the casing can be sealed and remained unused for a long time to achieve the effects of preventing internal electronic components from being exposed, maintaining the aesthetic appearance, preventing external pollutants from entering, and extending the lifespan of the electronic device.
