Abstract
A portable device comprising a housing (105, 110); a circuit board (125) located within the housing; and a tubular shield member (130) mounted at a first end (132) on the circuit board (125) so as to surround electronic components (14) on the circuit board to be shielded, wherein the device is arranged such that a metal portion of an exterior wall (120) of the housing electromagnetically seals off the shield member at its other second end (134).
Claims11
A portable device comprising a housing;
- a circuit board comprising a substrate and electronic components mounted on the substrate, the substrate and electronic components being located within the housing;
- a shield member having a first end mounted on the circuit board so as to surround electronic components on the circuit board to be shielded;
- and a gasket located at a second end of the shield member to facilitate electromagnetic sealing, wherein the device is arranged such that a conductive portion of an exterior wall of the housing electromagnetically seals off the shield member at the second end, and wherein the housing surrounds the substrate of the circuit board.
A portable device comprising a housing;
- a circuit board located within the housing;
- and a shield member having a first end mounted on the circuit board so as to surround electronic components on the circuit board to be shielded, wherein the device is arranged such that a conductive portion of an exterior wall of the housing contacts an end edge of the shield member at a second end of the shield member and electromagnetically seals off an opening into the shield member at the second end of the shield member, and wherein the exterior wall is made from plastics material and the conductive portion comprises a metal coated region applied to the wall.
A portable device comprising a circuit board having a substrate and a plurality of electronic components mounted upon at least one surface of the substrate, some of which electronic components require electromagnetic shielding and some of which do not require electromagnetic shielding, a housing surrounding the substrate of the circuit board, the housing having a conductive portion, and a shield member having a first end mounted on the circuit board so as to surround those electronic components on the circuit board to be shielded and a second end defining an opening into the shield member, wherein the device is arranged such that the conductive portion of the housing electromagnetically seals off the opening into the shield member at the second end of the shield member.
A portable device comprising a housing having a conductive portion;
- a circuit board located within the housing;
- and a shield member, the circuit board comprising first and second electronic components located within the housing and mounted to at least one surface of the circuit board, wherein the shield member has a first end mounted on the circuit board to be shielded and the shield member does not surround the second electronic component, wherein the device is arranged such that a second end of the shield member is mounted edge on to the conductive portion of the housing to electromagnetically seal off an opening into the shield member at the second end of the shield member.
A portable device comprising a housing having a conductive portion;
- a circuit board located within the housing;
- and a shield member, the circuit board comprising first and second electronic components located within the housing and mounted to at least one surface of the circuit board, wherein the shield member is positioned to separate the first and second electronic components and has a first end mounted on the circuit board and a second end mounted edge on to the conductive portion of the housing to provide electromagnetic sealing of the electronic components from one another.
A portable device comprising a housing;
- a circuit board located within the housing;
- and a shield member mounted at a first end on the circuit board so as to surround electronic components on the circuit board to be shielded, wherein the device is arranged such that a conductive portion of an exterior wall of the housing electromagnetically seals off the shield member at a second end, further comprising a gasket located at the second end of the shield member to facilitate electromagnetic sealing, the gasket comprising a planar framework of limbs;
- means for securing the gasket to the shield member and a plurality of spring tabs which bear against the metal portion of the exterior wall.
