Abstract:
PROBLEM TO BE SOLVED: To miniaturize a mounted circuit board and an electrical junction box housing it. SOLUTION: Output terminals 12 are arranged outwards in one row by mounting transistors 10 with control terminals 13 protruded downwards output terminals 12 protruded sideways and input terminals 11 protruded to the side opposite to the control and output terminals on the circuit board 21 in one row, and these terminals are inserted into a connector housing 41 as connector terminals, thus configuring an external connecting connector 40. Then, the input terminals 11 are joined with power supply bus bars 30 erected at the rear of the row of transistors 10, thus configuring the electrical junction box. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
A plug contact for electrically contacting a circuit board by inserting the plug contact into a via hole in the circuit board, the plug contact having two flat contact arms that are resilient relative to each other, and a connecting region, from which the two contact arms extend in the plug-in direction of the plug contact, the plug contact being punched as a single piece from a flat metallic material. In the connection region, adjacent to the two contact arms, a recess is formed in the plug contact, the distance between the two contact arms increases from the recess towards the free ends of the contact arms, the two contact arms being spread apart relative to each other and the two contact arms together having a width which is the same as or only slightly smaller than the diameter of the corresponding via hole in the circuit board.
Abstract:
An electronic device for a motor vehicle includes a metal tubular casing extending longitudinally and opening at its two ends, and a wall having a curved profile with cooling fins on its outer surface. The electronic device includes an assembly of printed circuit boards comprising a first plurality of printed circuit boards that include heat-generating electronic components. The printed circuit boards of the assembly are connected together by flexible conductive elements. The device further comprises a first heat sink arranged inside the tubular casing comprising a curved wall generally extending parallel to the curved wall of the tubular casing. The first plurality of printed circuit boards is interposed between the curved inner surface of the wall of the casing and the curved wall of the first heat sink so heat is dissipated through the first heat sink and through the curved wall equipped with cooling fins of the tubular casing.

Abstract:
An index signal output device where a magnetic flux detector is moved in the direction of a relevant tangent to the circumference of a rotor yoke so that the phase difference between an index signal detected by the magnetic flux detector and an index reference signal previously recorded on a floppy disk is within a prescribed range. The lead terminals of the magnetic flux detector are connected to detection signal output terminals on a printed circuit board, and the magnetic flux detector is moved for adjustment in the direction of the tangent by flexing the lead terminals using a tool.

Abstract:
A decoupling capacitor is mounted on a thin auxiliary board and connected by metallization traces on the board to a single pair of plug-in contacts press-fitted into a pair of apertures in a pair of integral tabs extending from the board. The auxiliary board and capacitor height is not more than about 0.070 inches. The plug-in contacts are pluggable into a pair of sockets in a printed circuit board. The auxiliary insulative board with its attached capacitor is sandwiched between a surface of a printed circuit board having a plurality of sockets, and the underside of a dual-in-line (DIP) integrated circuit package. At least two leads of the DIP package are inserted into the pair of insertable contacts in the auxliary isulative board while the remainder of the DIP package leads are inserted directly into other sockets in the printed circuit board. In one embodiment, other DIP leads pass through clearance holes in a second pair of integral tabs. Another embodiment provides for redundant capacitors each connected to separate pairs of contacts on the auxiliary board for interconnection of two ground leads and two power leads of the DIP to respective PC board sockets.
