Abstract:
The invention relates to a housing system for an electric device (1), which has at least two housing parts (2, 3) and an electronic circuit arranged on a circuit board (4) therein, provided with a conductive layer which is connected to the ground of at least one metallic housing part (2). The housing part (3) is made of a plastic part. At least the connecting device (9) for the voltage source of the device and/or the signal transmission to the electronic circuit is integrated therein. The circuit board (4) is covered on both sides. Perturbing-radiation-sensitive components (5) are arranged on the side thereof, and are continuously surrounded by the metallic housing part (2) and the conductive layer, and other components (6) and contacts of the connecting device (9) are arranged on the other side of the circuit board (4).
Abstract:
A stand-off mounting apparatus (10/50/80) includes an insulative carrier (12/52/82) for off-board mounting of leaded or surface-mount components (18, 20/58-62/92-96), particularly large temperature-sensitive discrete components such as capacitors. The carrier (12/52/82) has a component-mounting surface that is elevated relative to the circuit board (14), and is positioned with respect to the circuit board (14) such that the circuit board area under the mounting surface of the carrier (12/52/82) is available for the placement of smaller non-temperature-sensitive components. The off-board components (18, 20/58-62/92-96) are mounted on the component-mounting surface of the carrier (12/52/82), and the carrier (82) may include support features (102) for providing additional mechanical support for the components (92-96). Electrical leads (16/56/88) for electrically coupling the elevated components (18, 20/58-62/92-96) to the circuit board (14) may be insert-molded in the carrier (12/52), or may be inserted into plated through-holes (110) in the carrier (82).
Abstract:
La présente invention se rapporte à une plaquette à circuits imprimés comportant des composants électriques, où les composants avec leurs corps isolés (3) sont placés dans des trous de passage (10) de la plaquette à circuits imprimés (9), et où ils sont légèrement en saillie sur le dessous et sur le dessus de la plaquette, en portant dans ces zones des surfaces de contact, lesquelles sont brasées à des pistes conductrices de la plaquette. Les extrémités inférieures des composants se terminent en forme de calotte hémisphérique ou en pointes arrondies et présentent des surfaces de contact inférieures correspondantes, lesquelles font saillie dans des pistes conductrices de la plaquette à circuits imprimés (9) se présentant sous forme de pastilles (7) et lesquelles sont brasées à ces dernières. Les extrémités supérieures des composants portent plusieurs surfaces de contact supérieures (1.1, 1.2) isolées les unes des autres, lesquelles sont reliées à des éléments de contact (2.1, 2.2) en saillie du corps (3) et reliées en pont autour des trous (10) de la plaquette à circuits imprimés, au moyen d'une pâte à braser (5), à des pistes conductrices (6) du dessus de la plaquette à circuits imprimés.
Abstract:
An electronic apparatus (100) includes a housing (10) a circuit board (20) held in the housing (10), and large electronic components (30,31) held in the housing (10) and electrically coupled to the circuit board (20). The housing (10) has a mounting surface (10a) and the electronic apparatus is mounted to an object at the mounting surface (10a). The large electronic components (30,31) are arranged in a three-dimensional manner with respect to the mounting surface (10a) in such a manner that at least one of the large electronic components (30) overlaps at least one of the large electronic components (30) in a direction toward the mounting surface.
