Abstract:
A capacitor holder comprises: a holding portion made of a resin to have a cylindrical inner wall surface, at least an outer peripheral portion of the inner wall surface being open, the holding portion being configured to hold a capacitor inserted through the opening into an inside of the inner wall surface while elastically deforming the resin; a fixed portion formed of the resin integrally with the holding portion and positioned opposite to the opening of the holding portion; a pair of fitting grooves formed at a pair of end surfaces of the fixed portion opposed to each other adjacent to the holding portion, the fitting grooves being configured to fittably engage with end edges of a printed circuit board to extend along a surface of the printed circuit board; and a proximity suppressor formed of the resin as a part of the fixed portion and configured to suppress portions of the fixed portion where the fitting grooves are formed from being brought into proximity each other.

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:
Die Erfindung betrifft eine Batteriebrücke (1) für eine elektronische Vorrichtung, vorzugsweise für ein elektronisches Implantat. Um einen Stromkreis einer derartigen Vorrichtung einfach und mittels eines automatischen Verfahrens aktivieren zu können, besitzt die Batteriebrücke erfindungsgemäß ein elektrisch leitendes erstes Kontaktelement (11), ein elektrisch leitendes zweites Kontaktelement (12) und einen Isolator (13), wobei das erste Kontaktelement und das zweite Kontaktelement ein schweißbares Material aufweisen, wobei in einem ersten Zustand der Batteriebrücke das erste Kontaktelement über einen vorgegebenen Luftspalt beabstandet von dem zweiten Kontaktelement angeordnet ist und das erste Kontaktelement durch den Luftspalt und den Isolator elektrisch von dem zweiten Kontaktelement isoliert ist, wobei die Batteriebrücke derart ausgebildet ist, dass sie mittels Verschweißen (40) des ersten Kontaktelements und des zweiten Kontaktelements miteinander in einen zweiten Zustand überführbar ist, bei dem der Luftspalt zwischen dem ersten Kontaktelement und dem zweiten Kontaktelement zumindest abschnittsweise elektrisch leitend geschlossen ist (42). Die Erfindung betrifft ferner ein Verfahren zum Aktivieren einer elektronischen Vorrichtung mit einem elektrischen Schaltkreis und einer derartigen Batteriebrücke.
