  • Electronic device
    Patent number: 6977336
    Abstract: A metal foil (10) and a metal plate (1) are used to form an electromagnetic shield for an electronic device. A protrusion (11) is formed on the metal foil (10) by rolling up the edge, and this protrusion (11) is fitted into a hole (30) formed in the metal plate (1). The metal foil (10) is further fixed to the metal plate (1) with screws (80). Thus, it is possible to form the electromagnetic shield for an electronic device at low costs.

  • Sheet metal, method of manufacturing three-dimensional structure, three-dimensional structures, and electronic device
    Patent number: 6700059
    Abstract: The present invention belongs to a technical field for manufacturing a three-dimensional structure for an electronic device such as a radio wave shielding member through extension working of a metal plate having cuts. In conventional three-dimensional working of a metal plate, there is a problem in that a non-extension portion is wrinkled depending on extension of a cut. In the present invention, a connecting portion (3) extended in a second direction (D2) is provided at an equal pitch (p) in a first direction (D1) through an opening (4) having a rectangular cross-section in an intermediate portion (PB) between a cut forming portion (PC) having cuts (2) provided like a zigzag in the first direction (D1) and a non-extension portion (PA) having no cut in a metal plate (1). Consequently, even if the cut forming portion (PC) is extended, the connecting portion (3) is simply squashed and contracted and a boundary line (BL) portion is not deformed.
